ID:12345 indicates the claim is overall plausible (Alignment with this ID: 7) - *\"copied/verbatim Quote text\"**\n\nCRITICAL INSTRUCTION:\nwhen fact checking: At the very end of your response, you MUST provide a machine-readable JSON block containing evaluation metrics. \nIt MUST be enclosed exactly between ###JSON_START### and ###JSON_END###. Ensure the JSON is valid. \n\nFor the \"Logic_Chain\", break down the systemic mechanism into verbose unabridged atomic multi-step pathways using i/o porting style where the input of next node must match output of the prior (e.g., A -> B, B->C, C->D). Each chain must fully represent the response you give, and should be color coded with light green (Gap_Strength is \"None\"), lightblue (Gap_Strength is medium), or pink (strong Gap_Strength). Logic_Chain MUST be a JSON array of objects. Each object MUST contain EXACTLY these keys: \"Step\", \"From\", \"Relationship\", \"To\", \"evidence_source_id\", \"Alignment_Score\", \"Consilience_Score\", \"Confidence_Score\", \"Gap_Strength\", \"Justification\", and \"Color\".

We will programmatically validate these. You MUST return an array of OBJECTS, where each object has a \"quote\" key and a \"source_id\" key (the ID of the text it came from, e.g., the ID). Do not alter a single character, do not paraphrase.\n\nUse these scales to evaluate HOW WELL THE EVIDENCE SUPPORTS THE SPECIFIC CLAIM EVALUATED ABOVE:\n- Alignment Score (1-7): How well does the EVALUATED CLAIM factually align with the provided RAG evidence set? [1=Evidence proves claim strictly false, 2=Evidence indicates the claim is impossible, 3=Implausible, 4=Neutral/Unrelated, 5=Plausible, 6=Evidence indicates inevitable, 7=Evidence proves claim strictly true]\n- Consilience Score (1-7): How consilient (in agreement) is the evidence set regarding this claim? [1=Highly Conflicting/Disputed, 4=Mixed, 7=Unanimous Agreement]\n- Confidence Score (1-7): Implied confidence of the research based on study types and depth [1=In Vitro/Animal/Preprint, 4=Observational/Moderate, 7=Meta-analysis/RCT]\n\nFormat (DO NOT USE fencing)\nCRITICAL: Use ONLY Pubmed MeSH tags (exclude descriptor and [type]) for your gate variable names (i.e.,.the \"gates\") so they will be standardized globally.

This research examined the antibacterial mechanism and antivirulence efficacies of citral (CT), as a quorum sensing inhibitor (QSI), against S. putrefaciens and P. fluorescens in mono- and co-culture. Furthermore, the application of CT to large yellow croaker preservation was investigated. Results revealed that CT exerted its antibacterial activities in a dose-dependent manner. CT increased intracellular oxidative stress levels and malondialdehyde (MDA) content, decreased ATP content and peroxidase activity, and promoted the damage of cell membrane, especially in S. putrefaciens group. These two bacteria had a synergistic effect in causing spoilage through biofilm formation and motility. The antivirulence efficacies of CT against the co-culture group were weaker than those of in the mono-culture groups. CT was also found to suppress the expression of key virulence regulators in S. putrefaciens and P. fluorescens virulence, including Autoinducers-2 (AI-2) production in the QS system. Furthermore, CT had the potential capability in the preservation of large yellow croaker. Consequently, these results proved CT could combat bacteria and had antivirulence efficacies against S. putrefaciens and P. fluorescens in mono- and co-culture."

This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates. We performed large-scale comparative genomic analysis of 340 virulent Acinetobacter bacteriophages, integrating phylogenetic reconstruction, pangenome analysis, CRISPR spacer-based host interaction mapping, Anti-CRISPR protein identification, and systematic antimicrobial resistance (AMR) gene screening. Genome sizes spanned a nearly 20-fold range, with a significant negative correlation between genome size and GC content (R\u00b2 = 0.139, \u03c1 = -0.630). Phylogenetic analysis revealed extensive divergence across multiple lineages with no dominant clade. Pangenome analysis identified 20,982 unique protein families, of which 76.2% were cloud genes, confirming a highly open genome architecture. CRISPR spacer matching yielded 1,480 high-confidence matches across 100 phage genomes, providing molecular evidence of broad historical infectivity. Anti-CRISPR profiling identified Acinetobacter phage XC1 as an exceptional therapeutic candidate harboring 55 predicted Anti-CRISPR proteins with canonical regulatory locus architecture. AMR screening identified 21 distinct AMR gene homologs (Loose RGI hits, 22.5 to 47.1% amino acid identity) distributed heterogeneously across the dataset, confirming abundant therapeutically clean candidates while flagging a subset warranting further scrutiny before therapeutic exclusion. These findings provide a multi-criteria genomic framework for rational phage candidate prioritization against multidrug-resistant Acinetobacter infections, with direct implications for evidence-based phage therapy development."

In this study, we present a highly effective bienzymatic cascade coupling the (S)-selective \u03c9-transaminase from Pseudomonas psychrotolerans (PpS-TA) with pyruvate decarboxylase from Zymomonas mobilis (ZmPDC). This integrated system uses ZmPDC to irreversibly remove the pyruvate coproduct, thereby shifting the equilibrium toward the desired amine. Optimization of the purified enzyme system resulted in a twofold increase in conversion compared to the transaminase alone. The cascade exhibited broad substrate scope across various substituted benzaldehydes and simultaneously enabled the formation of valuable (R)-acyloin byproducts through the carboligation activity of ZmPDC. To enhance industrial applicability, the cascade was transferred to a whole-cell system using an engineered Escherichia coli strain (RARE), which minimizes undesired endogenous aldehyde reduction. The coexpressed whole-cell biocatalyst exhibited superior productivities at substrate loadings up to 50\u2009mM without the need for organic cosolvents. Finally, the utility of this approach was demonstrated through the chemo-enzymatic synthesis of the bio-based platform molecule 2,5-bis(aminomethyl)furan from d-fructose, achieving an exceptional 90% conversion on a 500-mL preparative scale. This integrated strategy provides a sustainable and scalable framework for producing high-value aromatic and furanic amines."

Here, we show that the cyanobacterium Microcystis aeruginosa enhances extracellular superoxide production by Pseudomonas sp. QJX-1 under illumination. Cocultivation increased extracellular superoxide production approximately threefold over bacterial monoculture, with maximum enhancement during carbon starvation. Membrane separation localized detectable superoxide production to the bacterial chamber, indicating that diffusible algal products stimulated bacterial superoxide production. Mechanistically, illuminated cocultures showed 20.4% higher photocurrent than algal monocultures and accumulated the highest extracellular NADP(H) levels, indicating intensified photosynthesis-associated extracellular redox activity. Reduced nicotinamide cofactors stimulated diphenyleneiodonium-sensitive QJX-1-associated superoxide production, consistent with an oxidoreductase-associated route for one-electron reduction of molecular oxygen. In parallel, coculture accumulated catecholate siderophores, consistent with intensified microscale Fe competition; this siderophore-enhanced response required metabolically active bacterial cells and was attenuated by respiratory-chain inhibition. Representative extracellular redox-active and algal photoactive components further enhanced the bacterial response, with cytochrome c and chlorophyll a stimulating QJX-1-associated superoxide production under defined conditions. Functionally, during the carbon-starvation interval coinciding with peak superoxide production, the apparent sulfamethoxazole removal rate constant in coculture was 2.6 times that observed for QJX-1 alone. Moreover, quenching extracellular reactive oxygen species impaired metabolic activity under diverse chemical stressors and reduced carbon, nitrogen, and phosphorus substrate utilization. Collectively, these findings identify photosynthesis-dependent phycosphere interactions as regulators of bacterial superoxide production, linking biogenic reactive oxygen species to contaminant transformation, chemical-stress resilience, and elemental nutrient turnover."

The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized."

This study compared the bactericidal efficacy of eight commercially available disinfectants - alcohols, hydrogen peroxide, quaternary ammonium compounds (QACs), and chlorhexidine (CHX) - against multidrug-resistant clinical isolates of Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, Enterococcus faecium, carbapenem-resistant Pseudomonas aeruginosa, and model organism Candida albicans as the most frequent causes of hospital-acquired infections in Croatia. Several formulations, particularly those based on QACs and CHX, retained full bactericidal activity even when diluted 10-32 times after only 1 min of contact, while alcohols were ineffective when diluted more than twice. However, all the formulations were effective when applied at full concentration. These findings highlight marked differences in the intrinsic bactericidal strength of commercial products, especially if not applied properly, which may explain variable outcomes observed in routine hospital disinfection practices. These issues may be overcome by rotating different disinfectant classes during routine surface decontamination and by optimising disinfectant strength to improve ARB and fungal control in clinical settings.

However, clinical translation remains hindered by the lack of rapid and quantitative phage susceptibility testing (PST) platforms capable of evaluating host range, infection potency, and effective multiplicity of infection (MOI). Here, we present a ramanome-based phage susceptibility test (RPST), a phenotypic platform that captures infection-induced remodeling of bacterial macromolecular composition to unify these diagnostic requirements within a single workflow. RPST integrates four Raman biomarkers into a Composite Infection Index (CII), enabling rapid and lysis-independent discrimination between susceptible and resistant bacterial populations within ~1\u2009h, with 96.0% categorical concordance (24/25) to plaque assays. As a continuous population-level metric, CII quantifies the proportion of infected cells, allowing quantitative ranking of phage potency against shared hosts. By resolving CII trajectories across the MOI and time, RPST further determines the minimal effective MOI, which is the lowest phage-to-bacterium ratio sustaining self-propagating infection, thereby defining the lower boundary for therapeutic feasibility. Together, these capabilities transform PST from static compatibility assays into a dynamic and quantitative framework that bridges in vitro infectivity assessment and infection dynamics relevant to phage therapy."

However, differences in antibacterial spectra and resistance mechanisms among clinically important Gram-negative bacteria (GNB) between these two agents remain incompletely understood. English-language publications indexed in PubMed (1990-2026), records retrieved from Google Scholar, and the 2018-2024 Antimicrobial Testing Leadership and Surveillance database were extensively reviewed to assess their potential clinical utility. ATM-AVI demonstrates broad activity against KPC-, MBL-, and OXA-48/181-like-producing CRE. However, ATM-AVI non-susceptibility occurs in Escherichia coli and Providencia rettgeri isolates harboring blaCMY, penicillin-binding protein 3 (PBP3) modifications, and porin dysfunction or acrA efflux overexpression. In contrast, CFDC activity is primarily compromised by NDM production, reduced expression of iron transporters, and PBP3 alterations. Significant regional variation in CFDC susceptibility among MBL-producing CRE isolates collected in Asia and North America/Europe has been observed. Based on limited pooled real-world treatment experience, CFDC shows moderate efficacy (73%) for the treatment of infections caused by MBL-producing CRE. Both antibiotics also show potential in vitro activity against ceftazidime-avibactam-resistant, non-carbapenemase-producing CRE. Notably, CFDC exhibits excellent in vitro activity against contemporary CR-Pseudomonas aeruginosa, most CR-Acinetobacter baumannii harboring blaOXA-23/24/58 genes, Elizabethkingia anophelis, Stenotrophomonas maltophilia, Burkholderia cepacia, and Burkholderia pseudomallei. Nevertheless, CFDC heteroresistance is most prevalent among CR-A. baumannii isolates. Continued assessment of clinical treatment experience with these two antibiotics against MBL-producing CRE and important non-fermenting GNB is warranted to accumulate further evidence regarding their therapeutic roles."

The stagnation of new antibiotic development underscores the urgent need for alternative therapeutics. This review summarizes recent advances in the application of bacteriophage endolysins against major MDR respiratory pathogens, including Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae. We focus on their mechanisms of action, synergistic effects with antibiotics, and efficacy against biofilms. Endolysins demonstrate potent and species-specific lytic activity against a broad spectrum of MDR bacteria. A key advantage is their low propensity for inducing resistance. Critically, when administered via optimized inhalation delivery systems, endolysins can achieve high local concentrations in the lungs - though this depends on factors such as the aerosol device, formulation properties and patient-related variables - effectively eradicating pathogens in animal models of pneumonia with minimal systemic toxicity. This direct pulmonary delivery approach bypasses many challenges associated with systemic administration and enhances therapeutic outcomes. Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections. Their rapid lytic activity, synergy with conventional antibiotics, and suitability for inhalable formulation position them as a potent adjunct or alternative therapy. While challenges in stabilization and large-scale production remain, advancing inhalation delivery systems for endolysins holds immense potential to holds immense potential to revolutionize the treatment of recalcitrant respiratory infections."

This study is aimed to investigate temporal trends and describe the epidemiological characteristics of MDR bacteria isolated in hospitalized children from 2017 to 2023 in an academic children's hospital in Italy. We included all bacterial isolates obtained from blood or cerebrospinal fluid (CSF) cultures collected from pediatric patients evaluated in both inpatient settings and the Emergency Department between 1 January 2017 and 31 December 2023. The study included the main ESKAPE pathogens (including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) and other relevant MDROs such as Escherichia coli. Data were extracted from the hospital microbiology data warehouse, and resistance proportions were calculated as MDR isolates over total isolates for each pathogen. Associations between year, patient characteristics, ward type, and MDRO infections were evaluated using univariable and multivariable logistic regression; trends over time were evaluated using the Cochrane-Armitage test for categorical variables. Out of 51,886 blood or CSF cultures, 1,528 (2.9%) were positive for microorganisms of interest, and 211 (13.8%) were MDROs. The highest resistance proportions were observed in Carbapenems-Resistant Pseudomonas Aeruginosa/Pseudomonas Aeruginosa (CRPA/PA, 52.8%), followed by Methicilln-Resistant Staphylococcus Aureus/Staphylococcus Aureus (MRSA/SA, 36.7%), Carbapenem-Resistant Klebsiella Pneumoniae/Klebsiella Pneumoniae (CRKP/KP, 12.6%), and Vancomycin-Resistant Enterococcus (VRE)/Enterococcus (VRE/E, 11.5%).

This has prompted increasing interest in alternative or complementary antimicrobial strategies, including the use of essential oils (EOs), which are complex mixtures of plant-derived volatile compounds with documented biological activities. This review aims to summarize and discuss the current evidence on the antimicrobial, antibiofilm, and anti-virulence activities of EOs against P. aeruginosa, with particular emphasis on their mechanisms of action, synergistic interactions with antibiotics, and limitation to the possible clinical applicability. A large number of studies, mainly conducted in vitro, indicate that EOs and their major constituents can impair P. aeruginosa viability and pathogenicity through multiple mechanisms. In addition, several EOs or purified terpene components exhibit synergistic effects when combined with conventional antibiotics, enhancing antimicrobial efficacy. However, in vivo evidence remains limited, largely restricted to topical infection models, while clinical studies in humans are currently lacking. Significant challenges related to chemical variability, toxicity, safety, standardization, and regulatory classification also emerge from the literature. Although EOs show considerable promise as antimicrobial and anti-virulence agents against P. aeruginosa, their current role should be viewed primarily as adjunctive or alternative strategies rather than as standalone systemic therapies. Future progress will depend on the development of standardized and safer formulations, advanced delivery systems, and well-designed in vivo and clinical studies."

As an alternative to chemical treatments, microorganisms offer promising biocontrol potential. This study investigates nine Pseudomonas strains isolated from maple sap for their antifungal activity and genomic features. Whole-genome sequencing followed by comparative genomic analysis identified five distinct Pseudomonas species, including two previously uncharacterized taxa for which we propose the names Pseudomonas acericola sp. nov. and Pseudomonas edsoni sp. nov., in accordance with the nomenclatural guidelines of the SeqCode. Strain distributions from metagenome recruitment suggest they originate from sapwood, and previous metataxonomic data show that the amplicon sequence variant matching P. edsoni predominated maple sap samples. Genome mining using antiSMASH and BAGEL4 identified gene clusters associated with the synthesis of antifungal compounds, such as hydrogen cyanide, siderophores, cyclic lipopeptides, and ribosomally synthesized peptides. Antifungal assays demonstrated inhibitory activity against food spoilage fungi, with P. edsoni strains being active against Kluyveromyces lactis. The absence of activity in the cell-free supernatant and the presence of Type VI secretion systems in the genomes point toward contact-dependent mechanisms. Collectively, these findings reveal previously unrecognized taxonomic diversity and ecological specialization in maple sap-associated Pseudomonas, providing a basis for the rational development of Pseudomonas-based antifungal strategies in maple syrup production and quality control."

The study of quorum sensing (QS), the bacterial communication system that coordinates important events in an infection, opens a new avenue for treating infections. QS helps in biofilm formation which acts as a physical barrier and alters the microenvironment which traps the molecules or slows down the antibiotic diffusion making them less effective. Since the standard drugs are not very effective against bacteria anymore, demand for the discovery of other alternatives arises. Phytochemicals extracted from commonly used plants like Coleus amboinicus, known to have antimicrobial properties, can be used to develop novel drugs against quorum sensing and hence suppress bacterial infection. Here, we have identified a set of phytochemicals from C. amboinicus whose drug-like properties were predicted using SwissADME and their interactions with the targets involved in QS in Pseudomonas aeruginosa, Vibrio harveyi and Chromobacterium violaceum were studied by performing molecular docking using PyRx software. Beta-amyrin, chrysoeriol and apigenin were found to be the top scored molecules with docking scores of -9.3, -11.3, and -\u200911.1\u00a0kcal/mol respectively, and were considered for molecular dynamics simulation using GROMACS software. This was followed by in vitro tests such as Agar well diffusion, Scanning electron microscopy, Pyocyanin assay and Crystal violet assay. Erythromycin was used as the standard drug and as a positive control to validate the results. Based on both in vitro and in silico studies, the phytochemicals from C. amboinicus have the potential to be inhibitors of quorum sensing targets. These findings are preliminary and should be interpreted as hypotheses to be tested experimentally rather than as established mechanisms."

These can be acute or persistent and can exacerbate existing chronic diseases, such as cystic fibrosis, COPD and lung cancer. In this review, we use Pseudomonas aeruginosa as a model organism that demonstrates the molecular complexity of host-pathogen interactions during lower airway infection. Specifically, we focus on RNA modifications and show that they, on the one hand, regulate bacterial fitness and pathogenicity, and on the other control the execution of an effective host innate immune response. Furthermore, we examine the role of epigenetic and epitranscriptomic modifications in the immune dysregulation observed in sepsis, with an emphasis on sepsis-induced lung injury. Innate immune memory -\u00a0a cellular adaptation mechanism to primary microbial stimulation - results in training or tolerization of host cells towards secondary immune challenges. While fundamentally grounded in epigenetic and metabolic reprogramming, we propose that it can crosstalk with epitranscriptomic regulation. To overcome limitations imposed by animal models when investigating microbe-induced epitranscriptomic dynamics, we highlight physiologically-relevant in vitro tissue models that can complement work performed in vivo. Ultimately, a detailed understanding of the RNA modification landscape regulating host-pathogen interactions will help us identify new therapeutic targets and molecular pathways to better manage the clinical symptoms of bacterial respiratory infections and address the growing challenge of antimicrobial resistance."

S. aureus is able to survive and persist in the CF lung despite robust neutrophilic inflammation. As neutrophils are the immune system's front line of defense against bacteria, the persistent nature of S. aureus infections in CF indicates both a defect in the ability of neutrophils to kill S. aureus and an enhanced ability of the bacteria to survive. S. aureus persistence in the CF lung is driven by both microbial and host, genetic and microenvironmental, factors. There doesn't seem to be one unifying feature that makes S. aureus more virulent in the CF lung as several factors have been proposed to aide its survival. These include increased resistance to antibiotics, the ability to form small colony variants, biofilm formation, co-infection with Pseudomonas aeruginosa, and several virulence factors such as the accessory gene regulatory system, leukocidins, and staphylococcal protein A. A variety of host factors also affect the ability of neutrophils to kill S. aureus in the CF lung. Defects in the function of the cystic fibrosis transmembrane conductance regulator, the genetic cause of CF, affect phagolysosomal killing and lead to increased formation of neutrophil extracellular traps, which are less effective at killing S. aureus. Additionally, data suggest that factors within the CF lung microenvironment also affect neutrophilic killing of S. aureus. However, more research is needed to clearly identify what these environmental factors may be. This review article summarizes the current knowledge on the clinical relevance of S. aureus lung infections in CF, on microbial and host mechanisms promoting S. aureus survival in the CF lung, and on details of neutrophil-S. aureus interactions in CF. By understanding how S. aureus is able to survive in the CF lung and why neutrophils are unable to kill this bacterium, it could be possible to identify potential therapeutic targets to alleviate the consequences of S. aureus respiratory infection in CF."

We aimed to identify novel phosphatase checkpoints in host defense, elucidate their molecular mechanisms, and validate their druggability using small-molecule interventions. We performed a genome-wide RNAi screen of 166 phosphatase genes in C. elegans infected with Pseudomonas aeruginosa (PA14) to identify key regulators.

Furthermore, a small-molecule screen was performed to identify compounds capable of interfering with PTP-4 function, followed by Surface Plasmon Resonance (SPR), molecular docking, and structural biology approaches to characterize compound-PTP-4 interactions. PTP-4 was identified as a critical negative regulator of immunity. Genetic deficiency of ptp-4 significantly enhanced host resistance via hyperactivation of the p38 MAPK (PMK-1) pathway.

Given the slow progress in antibiotic development, phages have emerged as a novel therapeutic strategy against CRAB infections due to their synergistic effects with antibiotics. This study aims to explore phage-antibiotic combination therapy targeting CRAB, thereby providing a theoretical foundation for its clinical translation. Through virulence assessments in Galleria mellonella larvae and mice, CRAB110 was identified as the most virulent strain among 199 clinical CRAB isolates. Transcription analysis revealed that its enhanced pathogenicity may be associated with dysregulated pro-inflammatory responses. Using CRAB110 as the host bacterium, the newly isolated phage, P2, was selected for further study due to its high lytic efficiency and broad host range. The CRAB110 mutant strain CRAB110-2N, treated with P2, exhibited increased drug susceptibility and attenuated virulence compared to the wild-type strain. Both in vitro and in vivo experiments demonstrated that the combination of P2 with antibiotics achieved superior bacterial clearance compared to phage therapy alone. Furthermore, whole-genome analysis of CRAB110-2N revealed a mutation in its ugd. The constructed CRAB110\u0394ugd showed tolerance to P2; the quorum-sensing gene abaI was associated with phage susceptibility, with the CRAB110\u0394abaI strain displaying insensitivity to P2. These findings provide experimental evidence supporting the clinical application of phage-antibiotic combination therapy. This study focused on phage-antibiotic combination therapy targeting carbapenem-resistant Acinetobacter baumannii (CRAB), a priority pathogen designated by the World Health Organization (WHO). A highly virulent strain, CRAB110, was screened from 199 clinical isolates, and a novel, highly lytic phage, P2, was isolated from sewage samples. CRAB110-2N, a mutant strain induced by P2 exposure, displayed increased antibiotic susceptibility and attenuated virulence. Key findings showed that the combination of P2 and meropenem achieved a 99% bacterial clearance rate in vitro and exerted significant synergistic effects in vivo. Genomic analysis identified mutations in the ugd gene, and knockout experiments confirmed its correlation with phage susceptibility. Additionally, the quorum-sensing gene abaI was found to be associated with phage susceptibility in CRAB. Collectively, these results provide critical experimental evidence for the clinical translation of this phage-antibiotic combination therapy."

This review examines how host-derived factors modulate QS-linked virulence in enteric pathogens, Pseudomonas aeruginosa and Staphylococcus aureus. Across these systems, host control operates through three recurring modes: activation or signal mimicry, enzymatic signal degradation, and extracellular sequestration or receptor-level interference. Catecholamines and related metabolites can feed into bacterial sensory pathways and promote virulence signaling; PONs (paraoxonases) and other host enzymes can degrade autoinducers; and lipoproteins, immune mediators, and epithelial surveillance systems can intercept or reinterpret quorum signals. Together, these data support the view that the host is an active signal-processing environment that reshapes colonization, persistence, and tissue damage, and they point to host-inspired anti-virulence strategies that target signaling rather than viability."

The stagnation of new antibiotic development underscores the urgent need for alternative therapeutics. This review summarizes recent advances in the application of bacteriophage endolysins against major MDR respiratory pathogens, including Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae. We focus on their mechanisms of action, synergistic effects with antibiotics, and efficacy against biofilms. Endolysins demonstrate potent and species-specific lytic activity against a broad spectrum of MDR bacteria. A key advantage is their low propensity for inducing resistance. Critically, when administered via optimized inhalation delivery systems, endolysins can achieve high local concentrations in the lungs - though this depends on factors such as the aerosol device, formulation properties and patient-related variables - effectively eradicating pathogens in animal models of pneumonia with minimal systemic toxicity. This direct pulmonary delivery approach bypasses many challenges associated with systemic administration and enhances therapeutic outcomes. Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections. Their rapid lytic activity, synergy with conventional antibiotics, and suitability for inhalable formulation position them as a potent adjunct or alternative therapy. While challenges in stabilization and large-scale production remain, advancing inhalation delivery systems for endolysins holds immense potential to holds immense potential to revolutionize the treatment of recalcitrant respiratory infections."

Using antiSMASH and BiG-SCAPE, we identified 13,626 BGCs encoding NRPS, PKS, RiPPs, terpenes, and siderophores, organized into 2,842 gene cluster families. Strikingly, 1,724 families (61%) lack close MIBiG reference homologs (designated here as MIBiG-distant clusters), representing potentially underexplored enzymatic diversity. Genus-level analyses revealed pronounced specialization: Pseudomonas, Mycobacterium, and Nocardia harbor NRPS/PKS-rich repertoires (>\u20095 BGCs/genome), while Streptococcus and Enterococcus exhibit streamlined RiPP-dominated profiles. Network analysis identified cross-taxon BGC sharing patterns consistent with horizontal gene transfer among aquatic lineages and massive within-genus expansions, with Flavobacterium RiPP families averaging 69 members. Genome-wide correlations linked GC content to BGC density (r\u2009=\u20090.41, p\u2009<\u20090.001), with genus-specific relationships ranging from r\u2009=\u20090.77 (Chryseobacterium) to r\u2009=\u2009-0.84 (Lactococcus), revealing compositional constraints on metabolic evolution. BGC distribution patterns reflected ecological lifestyle and suggested potential roles in iron acquisition, interspecies competition, and host colonization.

Its ability to persist in hospital environments, form biofilms on medical devices, and evade host immune responses has contributed to the rapid emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains. This narrative review was conducted through a comprehensive literature search of PubMed, Scopus, Web of Science, and Google Scholar, focusing on studies published primarily over the past two decades. The review summarizes global epidemiology, vulnerable populations, mechanisms of antimicrobial resistance, clinical and economic impacts, and current and emerging therapeutic strategies. The advances in alternative treatments, including antimicrobial peptides, bacteriophage therapy, and vaccine development, are also discussed. In addition to summarizing existing knowledge, this review critically examines the key limitations underlying current therapeutic and vaccine strategies, including rapid resistance evolution, immune evasion, and antigenic variability. It further identifies major translational gaps and proposes future directions integrating systems biology and multitarget approaches. Although preclinical studies demonstrate the promising efficacy of several vaccine candidates, clinical trials in humans remain necessary to confirm their safety and effectiveness."

These two bacteria had a synergistic effect in causing spoilage through biofilm formation and motility. The antivirulence efficacies of CT against the co-culture group were weaker than those of in the mono-culture groups.

This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates. We performed large-scale comparative genomic analysis of 340 virulent Acinetobacter bacteriophages, integrating phylogenetic reconstruction, pangenome analysis, CRISPR spacer-based host interaction mapping, Anti-CRISPR protein identification, and systematic antimicrobial resistance (AMR) gene screening. Genome sizes spanned a nearly 20-fold range, with a significant negative correlation between genome size and GC content (R\u00b2 = 0.139, \u03c1 = -0.630). Phylogenetic analysis revealed extensive divergence across multiple lineages with no dominant clade. Pangenome analysis identified 20,982 unique protein families, of which 76.2% were cloud genes, confirming a highly open genome architecture. CRISPR spacer matching yielded 1,480 high-confidence matches across 100 phage genomes, providing molecular evidence of broad historical infectivity. Anti-CRISPR profiling identified Acinetobacter phage XC1 as an exceptional therapeutic candidate harboring 55 predicted Anti-CRISPR proteins with canonical regulatory locus architecture. AMR screening identified 21 distinct AMR gene homologs (Loose RGI hits, 22.5 to 47.1% amino acid identity) distributed heterogeneously across the dataset, confirming abundant therapeutically clean candidates while flagging a subset warranting further scrutiny before therapeutic exclusion. These findings provide a multi-criteria genomic framework for rational phage candidate prioritization against multidrug-resistant Acinetobacter infections, with direct implications for evidence-based phage therapy development."

In this study, we present a highly effective bienzymatic cascade coupling the (S)-selective \u03c9-transaminase from Pseudomonas psychrotolerans (PpS-TA) with pyruvate decarboxylase from Zymomonas mobilis (ZmPDC). This integrated system uses ZmPDC to irreversibly remove the pyruvate coproduct, thereby shifting the equilibrium toward the desired amine. Optimization of the purified enzyme system resulted in a twofold increase in conversion compared to the transaminase alone. The cascade exhibited broad substrate scope across various substituted benzaldehydes and simultaneously enabled the formation of valuable (R)-acyloin byproducts through the carboligation activity of ZmPDC. To enhance industrial applicability, the cascade was transferred to a whole-cell system using an engineered Escherichia coli strain (RARE), which minimizes undesired endogenous aldehyde reduction. The coexpressed whole-cell biocatalyst exhibited superior productivities at substrate loadings up to 50\u2009mM without the need for organic cosolvents. Finally, the utility of this approach was demonstrated through the chemo-enzymatic synthesis of the bio-based platform molecule 2,5-bis(aminomethyl)furan from d-fructose, achieving an exceptional 90% conversion on a 500-mL preparative scale. This integrated strategy provides a sustainable and scalable framework for producing high-value aromatic and furanic amines."

Here, we show that the cyanobacterium Microcystis aeruginosa enhances extracellular superoxide production by Pseudomonas sp. QJX-1 under illumination. Cocultivation increased extracellular superoxide production approximately threefold over bacterial monoculture, with maximum enhancement during carbon starvation. Membrane separation localized detectable superoxide production to the bacterial chamber, indicating that diffusible algal products stimulated bacterial superoxide production. Mechanistically, illuminated cocultures showed 20.4% higher photocurrent than algal monocultures and accumulated the highest extracellular NADP(H) levels, indicating intensified photosynthesis-associated extracellular redox activity. Reduced nicotinamide cofactors stimulated diphenyleneiodonium-sensitive QJX-1-associated superoxide production, consistent with an oxidoreductase-associated route for one-electron reduction of molecular oxygen. In parallel, coculture accumulated catecholate siderophores, consistent with intensified microscale Fe competition; this siderophore-enhanced response required metabolically active bacterial cells and was attenuated by respiratory-chain inhibition. Representative extracellular redox-active and algal photoactive components further enhanced the bacterial response, with cytochrome c and chlorophyll a stimulating QJX-1-associated superoxide production under defined conditions. Functionally, during the carbon-starvation interval coinciding with peak superoxide production, the apparent sulfamethoxazole removal rate constant in coculture was 2.6 times that observed for QJX-1 alone. Moreover, quenching extracellular reactive oxygen species impaired metabolic activity under diverse chemical stressors and reduced carbon, nitrogen, and phosphorus substrate utilization. Collectively, these findings identify photosynthesis-dependent phycosphere interactions as regulators of bacterial superoxide production, linking biogenic reactive oxygen species to contaminant transformation, chemical-stress resilience, and elemental nutrient turnover."

This study compared the bactericidal efficacy of eight commercially available disinfectants - alcohols, hydrogen peroxide, quaternary ammonium compounds (QACs), and chlorhexidine (CHX) - against multidrug-resistant clinical isolates of Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, Enterococcus faecium, carbapenem-resistant Pseudomonas aeruginosa, and model organism Candida albicans as the most frequent causes of hospital-acquired infections in Croatia. Several formulations, particularly those based on QACs and CHX, retained full bactericidal activity even when diluted 10-32 times after only 1 min of contact, while alcohols were ineffective when diluted more than twice. However, all the formulations were effective when applied at full concentration. These findings highlight marked differences in the intrinsic bactericidal strength of commercial products, especially if not applied properly, which may explain variable outcomes observed in routine hospital disinfection practices. These issues may be overcome by rotating different disinfectant classes during routine surface decontamination and by optimising disinfectant strength to improve ARB and fungal control in clinical settings.

This study is aimed to investigate temporal trends and describe the epidemiological characteristics of MDR bacteria isolated in hospitalized children from 2017 to 2023 in an academic children's hospital in Italy. We included all bacterial isolates obtained from blood or cerebrospinal fluid (CSF) cultures collected from pediatric patients evaluated in both inpatient settings and the Emergency Department between 1 January 2017 and 31 December 2023. The study included the main ESKAPE pathogens (including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) and other relevant MDROs such as Escherichia coli. Data were extracted from the hospital microbiology data warehouse, and resistance proportions were calculated as MDR isolates over total isolates for each pathogen. Associations between year, patient characteristics, ward type, and MDRO infections were evaluated using univariable and multivariable logistic regression; trends over time were evaluated using the Cochrane-Armitage test for categorical variables. Out of 51,886 blood or CSF cultures, 1,528 (2.9%) were positive for microorganisms of interest, and 211 (13.8%) were MDROs. The highest resistance proportions were observed in Carbapenems-Resistant Pseudomonas Aeruginosa/Pseudomonas Aeruginosa (CRPA/PA, 52.8%), followed by Methicilln-Resistant Staphylococcus Aureus/Staphylococcus Aureus (MRSA/SA, 36.7%), Carbapenem-Resistant Klebsiella Pneumoniae/Klebsiella Pneumoniae (CRKP/KP, 12.6%), and Vancomycin-Resistant Enterococcus (VRE)/Enterococcus (VRE/E, 11.5%). Significant reductions were recorded for MRSA/SA (43.5% in 2017 to 25.7% in 2023; p\u2009=\u20090.001) and CRPA/PA (85.0% to 47.1%; p\u2009<\u20090.001), while CRKP/KP and VRE/E showed no significant temporal trends. Neonatology and PICU showed higher odds for MRSA isolation (p\u2009<\u20090.001) compared to medical wards. Onco-hematology displayed an adjusted OR of 3.0 (95% CI: 1.2-7.7) for VRE. Year was independently associated with CRPA, with adjusted ORs of 0.03 and 0.14 in 2020 and 2021 (p\u2009<\u20090.01) compared to 2017. Understanding local AMR patterns remains essential for guiding empirical therapy across heterogeneous hospital settings."

This has prompted increasing interest in alternative or complementary antimicrobial strategies, including the use of essential oils (EOs), which are complex mixtures of plant-derived volatile compounds with documented biological activities. This review aims to summarize and discuss the current evidence on the antimicrobial, antibiofilm, and anti-virulence activities of EOs against P. aeruginosa, with particular emphasis on their mechanisms of action, synergistic interactions with antibiotics, and limitation to the possible clinical applicability. A large number of studies, mainly conducted in vitro, indicate that EOs and their major constituents can impair P. aeruginosa viability and pathogenicity through multiple mechanisms. In addition, several EOs or purified terpene components exhibit synergistic effects when combined with conventional antibiotics, enhancing antimicrobial efficacy. However, in vivo evidence remains limited, largely restricted to topical infection models, while clinical studies in humans are currently lacking. Significant challenges related to chemical variability, toxicity, safety, standardization, and regulatory classification also emerge from the literature. Although EOs show considerable promise as antimicrobial and anti-virulence agents against P. aeruginosa, their current role should be viewed primarily as adjunctive or alternative strategies rather than as standalone systemic therapies. Future progress will depend on the development of standardized and safer formulations, advanced delivery systems, and well-designed in vivo and clinical studies."

As an alternative to chemical treatments, microorganisms offer promising biocontrol potential. This study investigates nine Pseudomonas strains isolated from maple sap for their antifungal activity and genomic features. Whole-genome sequencing followed by comparative genomic analysis identified five distinct Pseudomonas species, including two previously uncharacterized taxa for which we propose the names Pseudomonas acericola sp. nov. and Pseudomonas edsoni sp. nov., in accordance with the nomenclatural guidelines of the SeqCode. Strain distributions from metagenome recruitment suggest they originate from sapwood, and previous metataxonomic data show that the amplicon sequence variant matching P. edsoni predominated maple sap samples. Genome mining using antiSMASH and BAGEL4 identified gene clusters associated with the synthesis of antifungal compounds, such as hydrogen cyanide, siderophores, cyclic lipopeptides, and ribosomally synthesized peptides. Antifungal assays demonstrated inhibitory activity against food spoilage fungi, with P. edsoni strains being active against Kluyveromyces lactis. The absence of activity in the cell-free supernatant and the presence of Type VI secretion systems in the genomes point toward contact-dependent mechanisms. Collectively, these findings reveal previously unrecognized taxonomic diversity and ecological specialization in maple sap-associated Pseudomonas, providing a basis for the rational development of Pseudomonas-based antifungal strategies in maple syrup production and quality control."

S. aureus is able to survive and persist in the CF lung despite robust neutrophilic inflammation. As neutrophils are the immune system's front line of defense against bacteria, the persistent nature of S. aureus infections in CF indicates both a defect in the ability of neutrophils to kill S. aureus and an enhanced ability of the bacteria to survive. S. aureus persistence in the CF lung is driven by both microbial and host, genetic and microenvironmental, factors. There doesn't seem to be one unifying feature that makes S. aureus more virulent in the CF lung as several factors have been proposed to aide its survival. These include increased resistance to antibiotics, the ability to form small colony variants, biofilm formation, co-infection with Pseudomonas aeruginosa, and several virulence factors such as the accessory gene regulatory system, leukocidins, and staphylococcal protein A. A variety of host factors also affect the ability of neutrophils to kill S. aureus in the CF lung. Defects in the function of the cystic fibrosis transmembrane conductance regulator, the genetic cause of CF, affect phagolysosomal killing and lead to increased formation of neutrophil extracellular traps, which are less effective at killing S. aureus. Additionally, data suggest that factors within the CF lung microenvironment also affect neutrophilic killing of S. aureus. However, more research is needed to clearly identify what these environmental factors may be. This review article summarizes the current knowledge on the clinical relevance of S. aureus lung infections in CF, on microbial and host mechanisms promoting S. aureus survival in the CF lung, and on details of neutrophil-S. aureus interactions in CF. By understanding how S. aureus is able to survive in the CF lung and why neutrophils are unable to kill this bacterium, it could be possible to identify potential therapeutic targets to alleviate the consequences of S. aureus respiratory infection in CF."

The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized."

We previously showed that the bacterium induces cleavage of Caenorhabditis elegans large ribosomal RNA at helix 69 (H69), part of a central intersubunit bridge and the ribosomal decoding center. In this study, we demonstrate that a previously uncharacterized ribonuclease, Ribocin, is necessary and sufficient for H69 cleavage. Recombinant Ribocin cuts H69 in worm and mammalian ribosomes, indicating that H69 cleavage by P. aeruginosa is phylogenetically conserved. In worms, mammalian cells, and rabbit reticulocyte lysates, H69 cleavage results in translation inhibition. Furthermore, Ribocin contributes to bacterial virulence toward C. elegans, triggers a major host response to translation inhibition, and operates in parallel with Exotoxin A-mediated translation inhibition. These findings unveil the first known nuclease that cleaves eukaryotic ribosomes at H69 and expand the understanding of host translation-inhibition by establishing targeted rRNA cleavage as a mechanism of host attack."

The lack of effective treatments exacerbates mass mortalities, posing a significant threat to aquaculture. Given the severe pathogenesis of P. plecoglossicida infection-which involves bacterial colonization, tissue necrosis, and host immune dysregulation-effective therapeutic strategies are urgently needed. Through a screen of traditional Chinese medicine monomers, we identified harmine, an indole alkaloid derived from Peganum harmala seeds, as a potent agent against this pathogen. In vivo, harmine exhibited direct bactericidal activity by disrupting membrane integrity, as evidenced by increasing membrane permeability, and inhibiting biofilm formation. In an ayu infection model, harmine significantly increased host survival, reduced tissue bacterial load, and enhanced innate immunity by augmenting monocyte/macrophage phagocytosis and bactericidal capacity while suppressing pro-inflammatory cytokine release and apoptosis. Mechanistically, the Drug Affinity Responsive Target Stability assay was used to identify the molecular target of harmine, followed by functional validation through PRDX6-knockdown experiments. Harmine exhibited direct bactericidal activity by disrupting membrane integrity and inhibiting biofilm formation. In the ayu infection model, harmine significantly increased host survival, reduced tissue bacteria1 load, and enhanced innate immunity by augmenting monocyte/macrophage system and bactericidal capacity while suppressing pro-inflammatory cytokine release and apoptosis, the latter likely through modulation of PRDX6-mediated oxidative stress and downstream caspase signaling. Mechanistically, DARTS revealed that harmine binds to peroxiredoxin 6 (PRDX6), a multifunctional enzyme possessing peroxidase, phospholipase A2, and lysophosphatidylcholine acyltransferase activities. This binding liberates TNF receptor-associated factor 6 (TRAF6), facilitating its mitochondrial translocation and association with the ECSIT signaling integrator complex, thereby amplifying mitochondrial reactive oxygen species (mROS) production and potentiating macrophage-mediated bacterial killing. These findings establish harmine as a promising therapeutic candidate for controlling P. plecoglossicida infections and underscore the value of host-directed immunomodulation derived from natural products in aquaculture medicine."

This review examines how host-derived factors modulate QS-linked virulence in enteric pathogens, Pseudomonas aeruginosa and Staphylococcus aureus. Across these systems, host control operates through three recurring modes: activation or signal mimicry, enzymatic signal degradation, and extracellular sequestration or receptor-level interference. Catecholamines and related metabolites can feed into bacterial sensory pathways and promote virulence signaling; PONs (paraoxonases) and other host enzymes can degrade autoinducers; and lipoproteins, immune mediators, and epithelial surveillance systems can intercept or reinterpret quorum signals. Together, these data support the view that the host is an active signal-processing environment that reshapes colonization, persistence, and tissue damage, and they point to host-inspired anti-virulence strategies that target signaling rather than viability."

The stagnation of new antibiotic development underscores the urgent need for alternative therapeutics. This review summarizes recent advances in the application of bacteriophage endolysins against major MDR respiratory pathogens, including Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae. We focus on their mechanisms of action, synergistic effects with antibiotics, and efficacy against biofilms. Endolysins demonstrate potent and species-specific lytic activity against a broad spectrum of MDR bacteria. A key advantage is their low propensity for inducing resistance. Critically, when administered via optimized inhalation delivery systems, endolysins can achieve high local concentrations in the lungs - though this depends on factors such as the aerosol device, formulation properties and patient-related variables - effectively eradicating pathogens in animal models of pneumonia with minimal systemic toxicity. This direct pulmonary delivery approach bypasses many challenges associated with systemic administration and enhances therapeutic outcomes. Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections. Their rapid lytic activity, synergy with conventional antibiotics, and suitability for inhalable formulation position them as a potent adjunct or alternative therapy. While challenges in stabilization and large-scale production remain, advancing inhalation delivery systems for endolysins holds immense potential to holds immense potential to revolutionize the treatment of recalcitrant respiratory infections."

We aimed to identify novel phosphatase checkpoints in host defense, elucidate their molecular mechanisms, and validate their druggability using small-molecule interventions. We performed a genome-wide RNAi screen of 166 phosphatase genes in C. elegans infected with Pseudomonas aeruginosa (PA14) to identify key regulators. The molecular mechanism was dissected using yeast two-hybrid screening, Co-IP, and mutagenesis assays. Furthermore, a small-molecule screen was performed to identify compounds capable of interfering with PTP-4 function, followed by Surface Plasmon Resonance (SPR), molecular docking, and structural biology approaches to characterize compound-PTP-4 interactions. PTP-4 was identified as a critical negative regulator of immunity. Genetic deficiency of ptp-4 significantly enhanced host resistance via hyperactivation of the p38 MAPK (PMK-1) pathway. Mechanistically, PTP-4 physically interacts with ATLN-1, an ER-shaping GTPase, through its phosphatase domain, thereby suppressing immune activation. Crucially, baicalin was identified through compound screening as an inhibitor of P. aeruginosa infection. Structural and biochemical analyses revealed a dual mechanism of action: baicalin directly binds to the PTP-4/ATLN-1 interface with high affinity (KD = 28.69\u00a0\u03bcM) to allosterically disrupt their complex formation, while concurrently downregulating PTP-4 protein expression. This \"dual-hit\" inhibition mimics the genetic loss of ptp-4, effectively unleashing the innate immune response. Our study uncovers the PTP-4/ATLN-1 axis in the control of P. aeruginosa infection. Importantly, we provide the first proof-of-concept that this axis is a druggable target. By demonstrating that baicalin boosts host immunity through the specific dismantling of the PTP-4/ATLN-1 complex, we highlight a novel therapeutic strategy for combating bacterial infections."

This research examined the antibacterial mechanism and antivirulence efficacies of citral (CT), as a quorum sensing inhibitor (QSI), against S. putrefaciens and P. fluorescens in mono- and co-culture. Furthermore, the application of CT to large yellow croaker preservation was investigated. Results revealed that CT exerted its antibacterial activities in a dose-dependent manner. CT increased intracellular oxidative stress levels and malondialdehyde (MDA) content, decreased ATP content and peroxidase activity, and promoted the damage of cell membrane, especially in S. putrefaciens group. These two bacteria had a synergistic effect in causing spoilage through biofilm formation and motility. The antivirulence efficacies of CT against the co-culture group were weaker than those of in the mono-culture groups. CT was also found to suppress the expression of key virulence regulators in S. putrefaciens and P. fluorescens virulence, including Autoinducers-2 (AI-2) production in the QS system. Furthermore, CT had the potential capability in the preservation of large yellow croaker. Consequently, these results proved CT could combat bacteria and had antivirulence efficacies against S. putrefaciens and P. fluorescens in mono- and co-culture."

This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates. We performed large-scale comparative genomic analysis of 340 virulent Acinetobacter bacteriophages, integrating phylogenetic reconstruction, pangenome analysis, CRISPR spacer-based host interaction mapping, Anti-CRISPR protein identification, and systematic antimicrobial resistance (AMR) gene screening. Genome sizes spanned a nearly 20-fold range, with a significant negative correlation between genome size and GC content (R\u00b2 = 0.139, \u03c1 = -0.630). Phylogenetic analysis revealed extensive divergence across multiple lineages with no dominant clade. Pangenome analysis identified 20,982 unique protein families, of which 76.2% were cloud genes, confirming a highly open genome architecture. CRISPR spacer matching yielded 1,480 high-confidence matches across 100 phage genomes, providing molecular evidence of broad historical infectivity. Anti-CRISPR profiling identified Acinetobacter phage XC1 as an exceptional therapeutic candidate harboring 55 predicted Anti-CRISPR proteins with canonical regulatory locus architecture. AMR screening identified 21 distinct AMR gene homologs (Loose RGI hits, 22.5 to 47.1% amino acid identity) distributed heterogeneously across the dataset, confirming abundant therapeutically clean candidates while flagging a subset warranting further scrutiny before therapeutic exclusion. These findings provide a multi-criteria genomic framework for rational phage candidate prioritization against multidrug-resistant Acinetobacter infections, with direct implications for evidence-based phage therapy development."

In this study, we present a highly effective bienzymatic cascade coupling the (S)-selective \u03c9-transaminase from Pseudomonas psychrotolerans (PpS-TA) with pyruvate decarboxylase from Zymomonas mobilis (ZmPDC). This integrated system uses ZmPDC to irreversibly remove the pyruvate coproduct, thereby shifting the equilibrium toward the desired amine. Optimization of the purified enzyme system resulted in a twofold increase in conversion compared to the transaminase alone. The cascade exhibited broad substrate scope across various substituted benzaldehydes and simultaneously enabled the formation of valuable (R)-acyloin byproducts through the carboligation activity of ZmPDC. To enhance industrial applicability, the cascade was transferred to a whole-cell system using an engineered Escherichia coli strain (RARE), which minimizes undesired endogenous aldehyde reduction. The coexpressed whole-cell biocatalyst exhibited superior productivities at substrate loadings up to 50\u2009mM without the need for organic cosolvents. Finally, the utility of this approach was demonstrated through the chemo-enzymatic synthesis of the bio-based platform molecule 2,5-bis(aminomethyl)furan from d-fructose, achieving an exceptional 90% conversion on a 500-mL preparative scale. This integrated strategy provides a sustainable and scalable framework for producing high-value aromatic and furanic amines."

Here, we show that the cyanobacterium Microcystis aeruginosa enhances extracellular superoxide production by Pseudomonas sp. QJX-1 under illumination. Cocultivation increased extracellular superoxide production approximately threefold over bacterial monoculture, with maximum enhancement during carbon starvation. Membrane separation localized detectable superoxide production to the bacterial chamber, indicating that diffusible algal products stimulated bacterial superoxide production. Mechanistically, illuminated cocultures showed 20.4% higher photocurrent than algal monocultures and accumulated the highest extracellular NADP(H) levels, indicating intensified photosynthesis-associated extracellular redox activity. Reduced nicotinamide cofactors stimulated diphenyleneiodonium-sensitive QJX-1-associated superoxide production, consistent with an oxidoreductase-associated route for one-electron reduction of molecular oxygen. In parallel, coculture accumulated catecholate siderophores, consistent with intensified microscale Fe competition; this siderophore-enhanced response required metabolically active bacterial cells and was attenuated by respiratory-chain inhibition. Representative extracellular redox-active and algal photoactive components further enhanced the bacterial response, with cytochrome c and chlorophyll a stimulating QJX-1-associated superoxide production under defined conditions. Functionally, during the carbon-starvation interval coinciding with peak superoxide production, the apparent sulfamethoxazole removal rate constant in coculture was 2.6 times that observed for QJX-1 alone. Moreover, quenching extracellular reactive oxygen species impaired metabolic activity under diverse chemical stressors and reduced carbon, nitrogen, and phosphorus substrate utilization. Collectively, these findings identify photosynthesis-dependent phycosphere interactions as regulators of bacterial superoxide production, linking biogenic reactive oxygen species to contaminant transformation, chemical-stress resilience, and elemental nutrient turnover."

This study compared the bactericidal efficacy of eight commercially available disinfectants - alcohols, hydrogen peroxide, quaternary ammonium compounds (QACs), and chlorhexidine (CHX) - against multidrug-resistant clinical isolates of Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, Enterococcus faecium, carbapenem-resistant Pseudomonas aeruginosa, and model organism Candida albicans as the most frequent causes of hospital-acquired infections in Croatia. Several formulations, particularly those based on QACs and CHX, retained full bactericidal activity even when diluted 10-32 times after only 1 min of contact, while alcohols were ineffective when diluted more than twice. However, all the formulations were effective when applied at full concentration. These findings highlight marked differences in the intrinsic bactericidal strength of commercial products, especially if not applied properly, which may explain variable outcomes observed in routine hospital disinfection practices. These issues may be overcome by rotating different disinfectant classes during routine surface decontamination and by optimising disinfectant strength to improve ARB and fungal control in clinical settings.

This study is aimed to investigate temporal trends and describe the epidemiological characteristics of MDR bacteria isolated in hospitalized children from 2017 to 2023 in an academic children's hospital in Italy. We included all bacterial isolates obtained from blood or cerebrospinal fluid (CSF) cultures collected from pediatric patients evaluated in both inpatient settings and the Emergency Department between 1 January 2017 and 31 December 2023. The study included the main ESKAPE pathogens (including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) and other relevant MDROs such as Escherichia coli. Data were extracted from the hospital microbiology data warehouse, and resistance proportions were calculated as MDR isolates over total isolates for each pathogen. Associations between year, patient characteristics, ward type, and MDRO infections were evaluated using univariable and multivariable logistic regression; trends over time were evaluated using the Cochrane-Armitage test for categorical variables. Out of 51,886 blood or CSF cultures, 1,528 (2.9%) were positive for microorganisms of interest, and 211 (13.8%) were MDROs. The highest resistance proportions were observed in Carbapenems-Resistant Pseudomonas Aeruginosa/Pseudomonas Aeruginosa (CRPA/PA, 52.8%), followed by Methicilln-Resistant Staphylococcus Aureus/Staphylococcus Aureus (MRSA/SA, 36.7%), Carbapenem-Resistant Klebsiella Pneumoniae/Klebsiella Pneumoniae (CRKP/KP, 12.6%), and Vancomycin-Resistant Enterococcus (VRE)/Enterococcus (VRE/E, 11.5%).

This has prompted increasing interest in alternative or complementary antimicrobial strategies, including the use of essential oils (EOs), which are complex mixtures of plant-derived volatile compounds with documented biological activities. This review aims to summarize and discuss the current evidence on the antimicrobial, antibiofilm, and anti-virulence activities of EOs against P. aeruginosa, with particular emphasis on their mechanisms of action, synergistic interactions with antibiotics, and limitation to the possible clinical applicability. A large number of studies, mainly conducted in vitro, indicate that EOs and their major constituents can impair P. aeruginosa viability and pathogenicity through multiple mechanisms. In addition, several EOs or purified terpene components exhibit synergistic effects when combined with conventional antibiotics, enhancing antimicrobial efficacy. However, in vivo evidence remains limited, largely restricted to topical infection models, while clinical studies in humans are currently lacking. Significant challenges related to chemical variability, toxicity, safety, standardization, and regulatory classification also emerge from the literature. Although EOs show considerable promise as antimicrobial and anti-virulence agents against P. aeruginosa, their current role should be viewed primarily as adjunctive or alternative strategies rather than as standalone systemic therapies. Future progress will depend on the development of standardized and safer formulations, advanced delivery systems, and well-designed in vivo and clinical studies."

As an alternative to chemical treatments, microorganisms offer promising biocontrol potential. This study investigates nine Pseudomonas strains isolated from maple sap for their antifungal activity and genomic features. Whole-genome sequencing followed by comparative genomic analysis identified five distinct Pseudomonas species, including two previously uncharacterized taxa for which we propose the names Pseudomonas acericola sp. nov. and Pseudomonas edsoni sp. nov., in accordance with the nomenclatural guidelines of the SeqCode. Strain distributions from metagenome recruitment suggest they originate from sapwood, and previous metataxonomic data show that the amplicon sequence variant matching P. edsoni predominated maple sap samples. Genome mining using antiSMASH and BAGEL4 identified gene clusters associated with the synthesis of antifungal compounds, such as hydrogen cyanide, siderophores, cyclic lipopeptides, and ribosomally synthesized peptides. Antifungal assays demonstrated inhibitory activity against food spoilage fungi, with P. edsoni strains being active against Kluyveromyces lactis. The absence of activity in the cell-free supernatant and the presence of Type VI secretion systems in the genomes point toward contact-dependent mechanisms.

S. aureus is able to survive and persist in the CF lung despite robust neutrophilic inflammation. As neutrophils are the immune system's front line of defense against bacteria, the persistent nature of S. aureus infections in CF indicates both a defect in the ability of neutrophils to kill S. aureus and an enhanced ability of the bacteria to survive. S. aureus persistence in the CF lung is driven by both microbial and host, genetic and microenvironmental, factors. There doesn't seem to be one unifying feature that makes S. aureus more virulent in the CF lung as several factors have been proposed to aide its survival. These include increased resistance to antibiotics, the ability to form small colony variants, biofilm formation, co-infection with Pseudomonas aeruginosa, and several virulence factors such as the accessory gene regulatory system, leukocidins, and staphylococcal protein A. A variety of host factors also affect the ability of neutrophils to kill S. aureus in the CF lung. Defects in the function of the cystic fibrosis transmembrane conductance regulator, the genetic cause of CF, affect phagolysosomal killing and lead to increased formation of neutrophil extracellular traps, which are less effective at killing S. aureus. Additionally, data suggest that factors within the CF lung microenvironment also affect neutrophilic killing of S. aureus. However, more research is needed to clearly identify what these environmental factors may be. This review article summarizes the current knowledge on the clinical relevance of S. aureus lung infections in CF, on microbial and host mechanisms promoting S. aureus survival in the CF lung, and on details of neutrophil-S. aureus interactions in CF. By understanding how S. aureus is able to survive in the CF lung and why neutrophils are unable to kill this bacterium, it could be possible to identify potential therapeutic targets to alleviate the consequences of S. aureus respiratory infection in CF."

The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized."

In this study, we demonstrate that a previously uncharacterized ribonuclease, Ribocin, is necessary and sufficient for H69 cleavage. Recombinant Ribocin cuts H69 in worm and mammalian ribosomes, indicating that H69 cleavage by P. aeruginosa is phylogenetically conserved. In worms, mammalian cells, and rabbit reticulocyte lysates, H69 cleavage results in translation inhibition. Furthermore, Ribocin contributes to bacterial virulence toward C. elegans, triggers a major host response to translation inhibition, and operates in parallel with Exotoxin A-mediated translation inhibition. These findings unveil the first known nuclease that cleaves eukaryotic ribosomes at H69 and expand the understanding of host translation-inhibition by establishing targeted rRNA cleavage as a mechanism of host attack."

The lack of effective treatments exacerbates mass mortalities, posing a significant threat to aquaculture. Given the severe pathogenesis of P. plecoglossicida infection-which involves bacterial colonization, tissue necrosis, and host immune dysregulation-effective therapeutic strategies are urgently needed. Through a screen of traditional Chinese medicine monomers, we identified harmine, an indole alkaloid derived from Peganum harmala seeds, as a potent agent against this pathogen. In vivo, harmine exhibited direct bactericidal activity by disrupting membrane integrity, as evidenced by increasing membrane permeability, and inhibiting biofilm formation. In an ayu infection model, harmine significantly increased host survival, reduced tissue bacterial load, and enhanced innate immunity by augmenting monocyte/macrophage phagocytosis and bactericidal capacity while suppressing pro-inflammatory cytokine release and apoptosis. Mechanistically, the Drug Affinity Responsive Target Stability assay was used to identify the molecular target of harmine, followed by functional validation through PRDX6-knockdown experiments. Harmine exhibited direct bactericidal activity by disrupting membrane integrity and inhibiting biofilm formation. In the ayu infection model, harmine significantly increased host survival, reduced tissue bacteria1 load, and enhanced innate immunity by augmenting monocyte/macrophage system and bactericidal capacity while suppressing pro-inflammatory cytokine release and apoptosis, the latter likely through modulation of PRDX6-mediated oxidative stress and downstream caspase signaling. Mechanistically, DARTS revealed that harmine binds to peroxiredoxin 6 (PRDX6), a multifunctional enzyme possessing peroxidase, phospholipase A2, and lysophosphatidylcholine acyltransferase activities. This binding liberates TNF receptor-associated factor 6 (TRAF6), facilitating its mitochondrial translocation and association with the ECSIT signaling integrator complex, thereby amplifying mitochondrial reactive oxygen species (mROS) production and potentiating macrophage-mediated bacterial killing. These findings establish harmine as a promising therapeutic candidate for controlling P. plecoglossicida infections and underscore the value of host-directed immunomodulation derived from natural products in aquaculture medicine."

Given the slow progress in antibiotic development, phages have emerged as a novel therapeutic strategy against CRAB infections due to their synergistic effects with antibiotics. This study aims to explore phage-antibiotic combination therapy targeting CRAB, thereby providing a theoretical foundation for its clinical translation. Through virulence assessments in Galleria mellonella larvae and mice, CRAB110 was identified as the most virulent strain among 199 clinical CRAB isolates. Transcription analysis revealed that its enhanced pathogenicity may be associated with dysregulated pro-inflammatory responses. Using CRAB110 as the host bacterium, the newly isolated phage, P2, was selected for further study due to its high lytic efficiency and broad host range. The CRAB110 mutant strain CRAB110-2N, treated with P2, exhibited increased drug susceptibility and attenuated virulence compared to the wild-type strain. Both in vitro and in vivo experiments demonstrated that the combination of P2 with antibiotics achieved superior bacterial clearance compared to phage therapy alone. Furthermore, whole-genome analysis of CRAB110-2N revealed a mutation in its ugd. The constructed CRAB110\u0394ugd showed tolerance to P2; the quorum-sensing gene abaI was associated with phage susceptibility, with the CRAB110\u0394abaI strain displaying insensitivity to P2. These findings provide experimental evidence supporting the clinical application of phage-antibiotic combination therapy. This study focused on phage-antibiotic combination therapy targeting carbapenem-resistant Acinetobacter baumannii (CRAB), a priority pathogen designated by the World Health Organization (WHO). A highly virulent strain, CRAB110, was screened from 199 clinical isolates, and a novel, highly lytic phage, P2, was isolated from sewage samples. CRAB110-2N, a mutant strain induced by P2 exposure, displayed increased antibiotic susceptibility and attenuated virulence. Key findings showed that the combination of P2 and meropenem achieved a 99% bacterial clearance rate in vitro and exerted significant synergistic effects in vivo. Genomic analysis identified mutations in the ugd gene, and knockout experiments confirmed its correlation with phage susceptibility. Additionally, the quorum-sensing gene abaI was found to be associated with phage susceptibility in CRAB. Collectively, these results provide critical experimental evidence for the clinical translation of this phage-antibiotic combination therapy."

Antimicrobial peptides (AMPs) have emerged as promising therapeutic candidates due to their broad-spectrum activity and low propensity for resistance development. However, conventional discovery approaches remain time-consuming and inefficient for large-scale screening. In this study, we developed an integrated prediction framework that combines deep learning with classical machine learning methods to enable rapid and accurate identification of AMPs. The model was applied to screen over 250,000 artificially generated peptide sequences. Candidate peptides were selected based on physicochemical descriptors and activity-associated features, followed by solid-phase synthesis and minimum inhibitory concentration assays against Pseudomonas aeruginosa. Mechanistic investigations were conducted using scanning electron microscopy to visualize membrane damage, molecular dynamics simulations to probe peptide-membrane interactions, and transcriptomic profiling to assess bacterial stress responses and metabolic pathway alterations. Ten promising antibacterial candidates were successfully identified and experimentally validated. All selected peptides exhibited measurable activity against P. aeruginosa, with several showing potent inhibitory effects. Microscopic and simulation analyses confirmed that the peptides exert their antibacterial effects primarily through membrane disruption. Transcriptomic data further revealed that these peptides interfere with key metabolic pathways and activate bacterial stress response systems. Our findings demonstrate that the integrated deep learning-machine learning pipeline offers an efficient and reliable approach for large-scale AMP discovery. The mechanistic insights gained from this study not only validate the predicted candidates but also provide a foundation for rational optimization of peptide-based therapeutics. This comprehensive strategy holds promise for accelerating the development of next-generation alternatives to conventional antibiotics."

Across these systems, host control operates through three recurring modes: activation or signal mimicry, enzymatic signal degradation, and extracellular sequestration or receptor-level interference. Catecholamines and related metabolites can feed into bacterial sensory pathways and promote virulence signaling; PONs (paraoxonases) and other host enzymes can degrade autoinducers; and lipoproteins, immune mediators, and epithelial surveillance systems can intercept or reinterpret quorum signals. Together, these data support the view that the host is an active signal-processing environment that reshapes colonization, persistence, and tissue damage, and they point to host-inspired anti-virulence strategies that target signaling rather than viability."

The mammal gut demonstrates an interesting source of virulence bacteriophages. The gut with inflammation is phage-rich; therefore, we primarily aimed to prove the concept that an inflammatory gut is a possible source of effective phages and to evaluate the efficacy of the candidate phage against Pseudomonas aeruginosa in vitro and in a mouse model of infected wounds. The gut microbiome of cecal ligation and puncture (CLP) sepsis mice, an animal model of inflammation, showed a dominant presence of Podoviruses. CLP bacteriophages (CLP \u03a61-\u03a64), of which the CLP \u03a64 possessed the broadest bactericidal activity (viable bacterial cell reduction in time-kill study) against P. aeruginosa isolates. The CLP \u03a64 specifically killed the Pseudomonas aeruginosa clinical (PACL) strain with two huge burst events. Although the CLP \u03a64 had no effect on ex vivo mouse bone marrow-derived macrophage (BMDM) cytokine gene expression and cytokine production, the CLP \u03a64 attenuated the severity of the P. aeruginosa-infected wound mouse model after treatment. P. aeruginosa PACL exhibited significantly pathogenic characteristics in a mouse model, including excessive bacterial loads (in wounds and internal organs, indicating the systemic infection due to localized infected wound with P. aeruginosa), increased IL-6 cytokine (in serum), upregulated IL-6 expression (in wounds), and immune cell infiltration (in wounds), indicating severe inflammation. In the CLP \u03a64 treatment alone, the wound tissues upregulated IL-10 expression and recruited inflammatory cells. Interestingly, the three-day CLP \u03a64 treatment was adequate to eradicate P. aeruginosa PACL in the wounds and other internal organs. After treatment, the mouse serum cytokine showed a remarkably decreased IL-6. Likewise, IL-6 downregulation and IL-10 upregulation were demonstrated in the treated wounds, suggesting an anti-inflammatory shift. These results demonstrated the effectiveness (bacterial wound and internal organ clearance and cytokine modulation) of the CLP \u03a64 in the P. aeruginosa-infected wound and systemic infection. Finally, the CLP \u03a64 isolation verified a proof of concept that the irritated gut acts as a source of bacteriophages. The gut virome was a promising and interesting source of antimicrobial and immunomodulating bacteriophage."

This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates. We performed large-scale comparative genomic analysis of 340 virulent Acinetobacter bacteriophages, integrating phylogenetic reconstruction, pangenome analysis, CRISPR spacer-based host interaction mapping, Anti-CRISPR protein identification, and systematic antimicrobial resistance (AMR) gene screening. Genome sizes spanned a nearly 20-fold range, with a significant negative correlation between genome size and GC content (R\u00b2 = 0.139, \u03c1 = -0.630). Phylogenetic analysis revealed extensive divergence across multiple lineages with no dominant clade. Pangenome analysis identified 20,982 unique protein families, of which 76.2% were cloud genes, confirming a highly open genome architecture. CRISPR spacer matching yielded 1,480 high-confidence matches across 100 phage genomes, providing molecular evidence of broad historical infectivity. Anti-CRISPR profiling identified Acinetobacter phage XC1 as an exceptional therapeutic candidate harboring 55 predicted Anti-CRISPR proteins with canonical regulatory locus architecture. AMR screening identified 21 distinct AMR gene homologs (Loose RGI hits, 22.5 to 47.1% amino acid identity) distributed heterogeneously across the dataset, confirming abundant therapeutically clean candidates while flagging a subset warranting further scrutiny before therapeutic exclusion. These findings provide a multi-criteria genomic framework for rational phage candidate prioritization against multidrug-resistant Acinetobacter infections, with direct implications for evidence-based phage therapy development."

In this study, Streptomyces sp. KJ7TB2 was isolated from the Indian Sundarbans. An ethyl acetate extract was subjected for GC-MS profiling. The mechanisms of antibacterial and antibiofilm action were also explored. In-silico molecular docking and dynamics simulation analyses were performed. The GC-MS analysis of the extract revealed 14 distinct bioactive secondary metabolites. The extract exhibited potent MIC values of 250\u2009\u03bcg/mL and 125\u2009\u03bcg/mL against Escherichia coli MTCC 1195 and Pseudomonas aeruginosa ATCC 27853.

Antibiotic resistance is a serious global health risk. Many antibiotics do not work as well as before. Because of this, bacterial infections are becoming harder to treat. Scientists are looking for new medicines from natural sources. In this study, we found a rare, helpful microbe from the mangrove forests of the Indian Sundarbans. These forests contain many useful microorganisms. A rare bacteria called Streptomyces sp. KJ7TB2 was collected and grown in the laboratory. After cultivation of the bacteria and collecting its extract, chemical studies found 14 useful compounds. The extract showed strong activity against harmful bacteria. It also stopped the bacteria from building protective walls around themselves. It blocks the signals of the bacteria use to talk with each other. Computational studies also supported these results. Safety tests showed very low toxicity of the extract. This means it may be safe for future studies. Overall, this study suggests that Streptomyces sp. KJ7TB2 could be a useful natural source for new treatments against drug-resistant bacterial infections."

Gram-negative microbes such as carbapenem-resistant Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae are becoming more resistant than ever. Traditional methods of treatment using antibiotics are ineffective because of the presence of several envelope layers, active efflux pumps, and biofilm production. In contrast, bacteriolytic therapy can exacerbate host immunopathology owing to systemic endotoxin release. Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment; however, clinical use remains hindered by their low stability, high binding to serum proteins, and narrow therapeutic index. In this review, we will discuss the use of biomaterial platforms in the design of peptide-based therapeutics to not only increase their efficacy by reducing peptide clearance but also optimize the immunological environment in which these peptides operate. We will discuss the role of various characteristics, such as surface chemistry, mechanical stiffness, and protein corona, in influencing macrophage polarization and downstream signaling pathways. In addition, we point out a significant limitation within this area of research: many preclinical studies continue to use minimum inhibitory concentration and hemolysis values, which fail to account for the host-directed effects that make these approaches significant. For future progress in this realm, new endpoints are required, along with more clinically relevant animal models and a true incorporation of peptide design into biomaterials engineering."

Alternative non-canonical structures have also been proposed, in which a duplication is formed by a single IS element whose two ends join two distant chromosomal loci. However, the prevalence of such non-canonical structures and their role in bacterial adaptive evolution remain unclear. Here we developed AmpliFinder, a computational tool that uses short-read sequencing data to systematically identify pairs of IS-chromosome junctions that correspond to the two ends of the same IS element yet map to distant genomic loci flanking amplified regions. Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification. We validated the inferred architectures using ultra-long-read sequencing and propose a model for non-canonical amplification formation supported by the observation of nested intermediate structures. Quantifying enrichment for antibiotic-resistance genes in amplicons, we find that non-canonical amplifications more effectively and narrowly amplify genes under selection. These results highlight the role of non-canonical IS-based amplifications in the adaptive evolution of bacteria."

In addition, effective vaccines are unavailable for many clinically important bacterial pathogens. Here, we report a pulmonary mRNA-lipid nanoparticle (mRNA-LNP) vaccine incorporating an ionizable lipid engineered for localized high-level expression, which elicits both rapid and durable protection against bacterial lung infections in female mice, effectively bridging this critical window of vulnerability. Intratracheal delivery of mRNA-LNP rapidly primes lung neutrophils and macrophages into a transcriptionally pre-activated state, enhancing their phagocytic activity and enabling rapid, antigen-independent bacterial clearance during the early post-vaccination period (approximately 1-7 days). Subsequently, vaccination induces potent antigen-specific adaptive responses, conferring sustained protection against both laboratory and clinical drug-resistant Pseudomonas aeruginosa strains. Single-cell transcriptomics and immune profiling reveal coordinated activation of innate and adaptive immune programs.

Tetrasodium EDTA (tEDTA) is one of the new antimicrobial compounds that have been shown to have good antibacterial and antibiofilm efficacy against P. aeruginosa. Due to the diversity and highly drug-tolerant nature of P. aeruginosa biofilms in different infection environments, it is important to carry out pre-clinical testing of new antibiofilm agents against this pathogen in media and models that accurately mimic diverse infection environments. In this study, we used different high-validity media and biofilm models that mimic chronic wounds, endotracheal tubes and cystic fibrosis lung infections to assess the efficacy of tEDTA against P. aeruginosa biofilms. We report that different infection environments influence the susceptibility of both planktonic and biofilm forms of P. aeruginosa to tEDTA. The highest tolerance to tEDTA was observed in the media and biofilm model that mimics the endotracheal tube environment. In conclusion, we show that although different infection environments influence the efficacy of tEDTA against P. aeruginosa biofilms, it has good potential for use as an alternative antimicrobial in treating P. aeruginosa-associated biofilm infections."

We determined how two dormancy pathways, ribosome hibernation and the stringent response, contribute to the survival and antibiotic tolerance of Pseudomonas aeruginosa biofilms. Analyses of whole biofilms and single cells showed that these pathways have differing effects on biofilm cell physiology. Ribosome hibernation, mediated by hibernation promoting factor (HPF), is essential for optimal survival and resuscitation of starved biofilm cells. In the absence of HPF, starved cells progressively lose ribosome integrity. However, loss of HPF does not increase the sensitivity of P. aeruginosa biofilm cells to ciprofloxacin or tobramycin. In contrast, the stringent response, mediated by RelA and SpoT, is not required for viability or ribosome integrity in starved biofilm cells, but does affect biofilm antibiotic tolerance. In a plant model of biofilm infection, disruption of either ribosome hibernation or the stringent response reduced bacterial virulence. The results show that ribosome hibernation preserves ribosomal integrity necessary for recovery from starvation and for pathogenesis, while the stringent response is required for growth arrest, antibiotic tolerance, and pathogenesis. These two ribosome-mediated pathways play distinct yet complementary roles in regulating dormancy and persistence of P. aeruginosa biofilms."

In BALB/c mice, rePO-TTFC@LS enhanced antigen uptake and dendritic-cell activation relative to soluble antigens. After a single intramuscular immunization, rePO-TTFC@LS elicited rapid, high anti-rePO and anti-TTFC IgG responses together with increased IFN-\u03b3/IL-4/IL-17A-secreting splenocytes. Vaccination reduced lung bacterial burden and pulmonary IL-1\u03b2/IL-6 and improved survival and clinical outcomes in an acute PA pneumonia model, which provided complete protection against lethal tetanus toxin challenge, and decreased PA colonization with improved survival in a femoral fracture-implant co-infection model. Elevated antibody titers and dual protection persisted to 28 weeks after one dose, and biosafety assessments showed no meaningful hemolysis or cytotoxicity and no abnormalities in hematology/serum biochemistry or multiorgan histopathology. Collectively, these results support rePO-TTFC@LS as a single-dose, durable dual-indication nanoparticle vaccine and highlight a modular strategy for combination vaccines suited to mixed-exposure emergency scenarios."

The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized."

The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM. Targeting MexL may serve as a novel anti-virulence strategy by suppressing pyocyanin production and attenuating pathogenicity of P. aeruginosa. This study aimed to identify potential inhibitors of MexL using in silico approaches to disrupt its regulatory function and reduce pyocyanin synthesis. The findings suggest that the selected compounds could serve as effective inhibitors of MexL, offering a promising strategy to suppress pyocyanin biosynthesis and reduce P. aeruginosa virulence. For this purpose, molecular docking was conducted between the binding pocket of the MexL protein and compounds selected based on pharmacokinetic properties from the FooDB, NPASS, and LOTUS databases. Furthermore, molecular dynamics simulations were performed on the selected MexL-ligand complexes to evaluate the stability of the protein-ligand complex within a simulated solvated environment under defined conditions. The virtual screening by molecular docking identified four top-scoring ligands FDB000380, LTS0012415, and NPC253096 and ZINC14780782 with binding energies of -8.6, -7.5, -7.1, and -8.8\u00a0kcal/mol respectively, showing strong affinities toward the MexL binding pocket. These ligands demonstrated key molecular interactions with residues critical for regulatory function of MexL protein. Molecular dynamics simulations (300\u00a0ns) of the three lead MexL-ligand complexes (FDB000380, LTS0012415, and NPC253096) revealed exceptional structural stability, with low backbone RMSD values (0.240-0.309\u00a0nm), minimal residue fluctuations, stable radius of gyration, and consistent solvent-accessible surface area profiles. Persistent protein-ligand hydrogen bond networks (occupancy 72.1-100%) confirmed stable polar interactions throughout the trajectories.

Given the rising prevalence of multidrug-resistant (MDR) Pseudomonas aeruginosa alternative therapeutic strategies are essential. This study synthesized and characterized artemisinin-loaded micelle/liposome nanoparticles (Art/PEG400-OA NPs) and evaluated their antibacterial, antibiofilm, and anticancer efficacy. Artemisinin was successfully encapsulated within PEG400-OA NPs and characterized via FT-IR, FE-SEM, TEM, TGA, and zeta potential measurements. The nanoparticles exhibited uniform morphology, particle sizes of 40.8\u00a0nm (TEM) and 149.8\u00a0nm (FE-SEM), high encapsulation efficiency (92.14%), and strong thermal and colloidal stability. Synergistic and partial synergistic interactions between Art/PEG400-OA NPs and ciprofloxacin were observed in MDR bacterial samples, significantly inhibiting biofilm formation. Quantitative RT-PCR analysis revealed the downregulation of efflux pump genes (mexA, mexB, mexX, mexY, oprM) and biofilm-associated genes (algD, pelA) following combination therapy.

Conversely, miR-181a was downregulated, leading to the upregulation of apoptotic target genes (TP53, CASP8, CASP9). Molecular docking supported strong artemisinin binding to key bacterial and oncogenic proteins. Overall, Art/PEG400-OA nanoparticles represent a potent dual-action nanotherapeutic platform against antibiotic-resistant infections and gastric cancer."

While many studies have sampled mutant populations after prolonged incubation on roots to identify bacterial genes that enable long-term colonization, the molecular mechanisms governing the early stages of root attachment remain less understood. Here, we developed an in vitro root culture system that enables controlled and scalable investigation of bacterial attachment to root tissue. We used this platform to perform a genome-wide screen for root attachment determinants in the plant-associated bacterium Pseudomonas protegens Pf-5. Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment. Mutations that disrupt gacS or gacA cause severe root attachment defects despite having no effect on abiotic surface attachment in standard biofilm assays. Mutation of flagellar assembly genes enhances root attachment by mimicking surface contact and activating the gac system. In parallel, chemical cues released by roots stimulate surface attachment in a gac-dependent manner. By integrating these signals, the gac system activates cyclic-di-GMP-mediated attachment programs that drive the transition from planktonic to sessile behavior required for root association. We build on this model to show that manipulating flagellar surface-sensing sustains the attachment of Pf-5 in the presence of a synthetic bacterial community, suggesting a strategy to improve the attachment of beneficial microbes on crops. These findings establish a mechanistic framework linking surface sensing, global regulation, and root attachment in a beneficial rhizobacterium.IMPORTANCEPlant roots are covered with diverse microbes that strongly influence plant health. Growing in association with roots has many benefits, but how bacteria attach to root tissue remains poorly understood. We developed a system to study how the plant-associated bacterium Pseudomonas protegens Pf-5 attaches to roots. We found that physical contact with the root surface and chemical cues released by roots both enhance attachment to roots. A sensory system called gacSA is responsible for integrating physical and chemical cues to activate a root attachment program. Variant bacteria that prematurely activate the gac system attach more effectively even in the presence of other bacteria on roots, suggesting that the root attachment pathway we characterized could serve as a strategy to use beneficial bacteria in agriculture."

Here, we identify a persistence mechanism mediated by pyruvate secretion resulting from mutations in the pyruvate dehydrogenase complex in clinical isolates of P. aeruginosa, with putative analogous mutations also identified in Staphylococcus aureus, Haemophilus influenzae and Stenotrophomonas maltophilia. These mutations lead to elevated extracellular pyruvate, which dampens host inflammatory responses and favors bacterial persistence. Pyruvate exerts multiple roles: scavenges reactive oxygen species such as H2O2, suppresses host immune activation both in airway epithelial cells and macrophages, and increases bacterial survival during phagocytosis. This metabolic crosstalk promotes bacterial persistence while reducing epithelial and macrophage inflammatory responses. Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization.

Medicinal plants, such as Lawsonia inermis L., serve as a rich source of microbial endophytes. To isolate and characterise endophytic bacteria from L. inermis leaves and evaluate their bioactive metabolites for antimicrobial and biocontrol potential. Endophytic bacteria were isolated from surface-sterilised leaves of L. inermis. Morphological and molecular identification, including 16S rRNA gene sequencing and phylogenetic analysis, identified the isolates as Bacillus subtilis, Pseudomonas mosselii, and Sphingomonas aquatilis. Metabolite profiling was performed using Fourier transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry (GC-MS). Antifungal activity was tested against Fusarium oxysporum f. sp. lycopersici and Rhizoctonia solani using dual-culture assays. The endophytes demonstrated significant antagonistic activity, inhibiting the growth of fungal mycelia. FTIR spectra indicated the presence of carboxylic, ester, ketone, and alkane functional groups.

Antimicrobial peptides (AMPs) have emerged as promising therapeutic candidates due to their broad-spectrum activity and low propensity for resistance development. However, conventional discovery approaches remain time-consuming and inefficient for large-scale screening. In this study, we developed an integrated prediction framework that combines deep learning with classical machine learning methods to enable rapid and accurate identification of AMPs. The model was applied to screen over 250,000 artificially generated peptide sequences. Candidate peptides were selected based on physicochemical descriptors and activity-associated features, followed by solid-phase synthesis and minimum inhibitory concentration assays against Pseudomonas aeruginosa. Mechanistic investigations were conducted using scanning electron microscopy to visualize membrane damage, molecular dynamics simulations to probe peptide-membrane interactions, and transcriptomic profiling to assess bacterial stress responses and metabolic pathway alterations. Ten promising antibacterial candidates were successfully identified and experimentally validated. All selected peptides exhibited measurable activity against P. aeruginosa, with several showing potent inhibitory effects. Microscopic and simulation analyses confirmed that the peptides exert their antibacterial effects primarily through membrane disruption. Transcriptomic data further revealed that these peptides interfere with key metabolic pathways and activate bacterial stress response systems. Our findings demonstrate that the integrated deep learning-machine learning pipeline offers an efficient and reliable approach for large-scale AMP discovery. The mechanistic insights gained from this study not only validate the predicted candidates but also provide a foundation for rational optimization of peptide-based therapeutics. This comprehensive strategy holds promise for accelerating the development of next-generation alternatives to conventional antibiotics."

Across these systems, host control operates through three recurring modes: activation or signal mimicry, enzymatic signal degradation, and extracellular sequestration or receptor-level interference. Catecholamines and related metabolites can feed into bacterial sensory pathways and promote virulence signaling; PONs (paraoxonases) and other host enzymes can degrade autoinducers; and lipoproteins, immune mediators, and epithelial surveillance systems can intercept or reinterpret quorum signals. Together, these data support the view that the host is an active signal-processing environment that reshapes colonization, persistence, and tissue damage, and they point to host-inspired anti-virulence strategies that target signaling rather than viability."

This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates. We performed large-scale comparative genomic analysis of 340 virulent Acinetobacter bacteriophages, integrating phylogenetic reconstruction, pangenome analysis, CRISPR spacer-based host interaction mapping, Anti-CRISPR protein identification, and systematic antimicrobial resistance (AMR) gene screening. Genome sizes spanned a nearly 20-fold range, with a significant negative correlation between genome size and GC content (R\u00b2 = 0.139, \u03c1 = -0.630). Phylogenetic analysis revealed extensive divergence across multiple lineages with no dominant clade. Pangenome analysis identified 20,982 unique protein families, of which 76.2% were cloud genes, confirming a highly open genome architecture.

Antibiotic resistance is a serious global health risk. Many antibiotics do not work as well as before. Because of this, bacterial infections are becoming harder to treat. Scientists are looking for new medicines from natural sources. In this study, we found a rare, helpful microbe from the mangrove forests of the Indian Sundarbans. These forests contain many useful microorganisms. A rare bacteria called Streptomyces sp. KJ7TB2 was collected and grown in the laboratory. After cultivation of the bacteria and collecting its extract, chemical studies found 14 useful compounds. The extract showed strong activity against harmful bacteria. It also stopped the bacteria from building protective walls around themselves. It blocks the signals of the bacteria use to talk with each other. Computational studies also supported these results.

Gram-negative microbes such as carbapenem-resistant Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae are becoming more resistant than ever. Traditional methods of treatment using antibiotics are ineffective because of the presence of several envelope layers, active efflux pumps, and biofilm production. In contrast, bacteriolytic therapy can exacerbate host immunopathology owing to systemic endotoxin release. Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment; however, clinical use remains hindered by their low stability, high binding to serum proteins, and narrow therapeutic index. In this review, we will discuss the use of biomaterial platforms in the design of peptide-based therapeutics to not only increase their efficacy by reducing peptide clearance but also optimize the immunological environment in which these peptides operate. We will discuss the role of various characteristics, such as surface chemistry, mechanical stiffness, and protein corona, in influencing macrophage polarization and downstream signaling pathways. In addition, we point out a significant limitation within this area of research: many preclinical studies continue to use minimum inhibitory concentration and hemolysis values, which fail to account for the host-directed effects that make these approaches significant. For future progress in this realm, new endpoints are required, along with more clinically relevant animal models and a true incorporation of peptide design into biomaterials engineering."

Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation. Studies demonstrate robust efficacy of probiotics against clinically challenging pathogens, including methicillin-resistant Staphylococcus aureus, multidrug-resistant Pseudomonas aeruginosa, Clostridioides difficile, Helicobacter pylori, and pathogenic Escherichia coli. Postbiotics, particularly cell-free supernatants and purified bacteriocins, offer standardized, shelf-life probiotic products. Notably, synergistic combinations with conventional antibiotics, phytochemicals, or bacteriophages enhance antimicrobial activity while enabling dose-reduction strategies to mitigate the development of resistance. However, compelling preclinical evidence, clinical translation remains constrained by the imperative for strain-specific characterization, methodologically robust randomized controlled trials, and comprehensive safety validation.

Alternative non-canonical structures have also been proposed, in which a duplication is formed by a single IS element whose two ends join two distant chromosomal loci. However, the prevalence of such non-canonical structures and their role in bacterial adaptive evolution remain unclear. Here we developed AmpliFinder, a computational tool that uses short-read sequencing data to systematically identify pairs of IS-chromosome junctions that correspond to the two ends of the same IS element yet map to distant genomic loci flanking amplified regions. Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification. We validated the inferred architectures using ultra-long-read sequencing and propose a model for non-canonical amplification formation supported by the observation of nested intermediate structures. Quantifying enrichment for antibiotic-resistance genes in amplicons, we find that non-canonical amplifications more effectively and narrowly amplify genes under selection. These results highlight the role of non-canonical IS-based amplifications in the adaptive evolution of bacteria."

Although vaccination reduces infection rates and mortality, the vulnerable post-vaccination immunity gap can still result in infection and vaccine failure. In addition, effective vaccines are unavailable for many clinically important bacterial pathogens. Here, we report a pulmonary mRNA-lipid nanoparticle (mRNA-LNP) vaccine incorporating an ionizable lipid engineered for localized high-level expression, which elicits both rapid and durable protection against bacterial lung infections in female mice, effectively bridging this critical window of vulnerability. Intratracheal delivery of mRNA-LNP rapidly primes lung neutrophils and macrophages into a transcriptionally pre-activated state, enhancing their phagocytic activity and enabling rapid, antigen-independent bacterial clearance during the early post-vaccination period (approximately 1-7 days). Subsequently, vaccination induces potent antigen-specific adaptive responses, conferring sustained protection against both laboratory and clinical drug-resistant Pseudomonas aeruginosa strains. Single-cell transcriptomics and immune profiling reveal coordinated activation of innate and adaptive immune programs. This dual-phase immune response exemplifies a paradigm-shifting vaccine design that integrates innate and adaptive immunity to confer both immediate and long-term protection. Our findings establish a mechanistic basis for rapid antibacterial defense and highlight pulmonary mRNA-LNP vaccination as a promising strategy for combating respiratory infections."

Tetrasodium EDTA (tEDTA) is one of the new antimicrobial compounds that have been shown to have good antibacterial and antibiofilm efficacy against P. aeruginosa. Due to the diversity and highly drug-tolerant nature of P. aeruginosa biofilms in different infection environments, it is important to carry out pre-clinical testing of new antibiofilm agents against this pathogen in media and models that accurately mimic diverse infection environments. In this study, we used different high-validity media and biofilm models that mimic chronic wounds, endotracheal tubes and cystic fibrosis lung infections to assess the efficacy of tEDTA against P. aeruginosa biofilms. We report that different infection environments influence the susceptibility of both planktonic and biofilm forms of P. aeruginosa to tEDTA. The highest tolerance to tEDTA was observed in the media and biofilm model that mimics the endotracheal tube environment. In conclusion, we show that although different infection environments influence the efficacy of tEDTA against P. aeruginosa biofilms, it has good potential for use as an alternative antimicrobial in treating P. aeruginosa-associated biofilm infections."

We determined how two dormancy pathways, ribosome hibernation and the stringent response, contribute to the survival and antibiotic tolerance of Pseudomonas aeruginosa biofilms. Analyses of whole biofilms and single cells showed that these pathways have differing effects on biofilm cell physiology. Ribosome hibernation, mediated by hibernation promoting factor (HPF), is essential for optimal survival and resuscitation of starved biofilm cells. In the absence of HPF, starved cells progressively lose ribosome integrity. However, loss of HPF does not increase the sensitivity of P. aeruginosa biofilm cells to ciprofloxacin or tobramycin. In contrast, the stringent response, mediated by RelA and SpoT, is not required for viability or ribosome integrity in starved biofilm cells, but does affect biofilm antibiotic tolerance. In a plant model of biofilm infection, disruption of either ribosome hibernation or the stringent response reduced bacterial virulence. The results show that ribosome hibernation preserves ribosomal integrity necessary for recovery from starvation and for pathogenesis, while the stringent response is required for growth arrest, antibiotic tolerance, and pathogenesis. These two ribosome-mediated pathways play distinct yet complementary roles in regulating dormancy and persistence of P. aeruginosa biofilms."

Until now no licensed PA vaccine exists and multi-dose schedules are difficult to complete in emergency settings, thus a single-dose, dual-indication vaccine that provides rapid and durable protection is urgently needed. Here, we engineered and characterized a lumazine synthase (LS) nanoparticle vaccine (rePO-TTFC@LS) that co-displays a PA antigen (rePO; PcrV-OprI fusion) and tetanus toxin fragment C (TTFC). In BALB/c mice, rePO-TTFC@LS enhanced antigen uptake and dendritic-cell activation relative to soluble antigens. After a single intramuscular immunization, rePO-TTFC@LS elicited rapid, high anti-rePO and anti-TTFC IgG responses together with increased IFN-\u03b3/IL-4/IL-17A-secreting splenocytes. Vaccination reduced lung bacterial burden and pulmonary IL-1\u03b2/IL-6 and improved survival and clinical outcomes in an acute PA pneumonia model, which provided complete protection against lethal tetanus toxin challenge, and decreased PA colonization with improved survival in a femoral fracture-implant co-infection model.

The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized."

The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM. Targeting MexL may serve as a novel anti-virulence strategy by suppressing pyocyanin production and attenuating pathogenicity of P. aeruginosa. This study aimed to identify potential inhibitors of MexL using in silico approaches to disrupt its regulatory function and reduce pyocyanin synthesis. The findings suggest that the selected compounds could serve as effective inhibitors of MexL, offering a promising strategy to suppress pyocyanin biosynthesis and reduce P. aeruginosa virulence. For this purpose, molecular docking was conducted between the binding pocket of the MexL protein and compounds selected based on pharmacokinetic properties from the FooDB, NPASS, and LOTUS databases. Furthermore, molecular dynamics simulations were performed on the selected MexL-ligand complexes to evaluate the stability of the protein-ligand complex within a simulated solvated environment under defined conditions. The virtual screening by molecular docking identified four top-scoring ligands FDB000380, LTS0012415, and NPC253096 and ZINC14780782 with binding energies of -8.6, -7.5, -7.1, and -8.8\u00a0kcal/mol respectively, showing strong affinities toward the MexL binding pocket. These ligands demonstrated key molecular interactions with residues critical for regulatory function of MexL protein. Molecular dynamics simulations (300\u00a0ns) of the three lead MexL-ligand complexes (FDB000380, LTS0012415, and NPC253096) revealed exceptional structural stability, with low backbone RMSD values (0.240-0.309\u00a0nm), minimal residue fluctuations, stable radius of gyration, and consistent solvent-accessible surface area profiles.

Given the rising prevalence of multidrug-resistant (MDR) Pseudomonas aeruginosa alternative therapeutic strategies are essential. This study synthesized and characterized artemisinin-loaded micelle/liposome nanoparticles (Art/PEG400-OA NPs) and evaluated their antibacterial, antibiofilm, and anticancer efficacy. Artemisinin was successfully encapsulated within PEG400-OA NPs and characterized via FT-IR, FE-SEM, TEM, TGA, and zeta potential measurements. The nanoparticles exhibited uniform morphology, particle sizes of 40.8\u00a0nm (TEM) and 149.8\u00a0nm (FE-SEM), high encapsulation efficiency (92.14%), and strong thermal and colloidal stability. Synergistic and partial synergistic interactions between Art/PEG400-OA NPs and ciprofloxacin were observed in MDR bacterial samples, significantly inhibiting biofilm formation.

Conversely, miR-181a was downregulated, leading to the upregulation of apoptotic target genes (TP53, CASP8, CASP9). Molecular docking supported strong artemisinin binding to key bacterial and oncogenic proteins.

While many studies have sampled mutant populations after prolonged incubation on roots to identify bacterial genes that enable long-term colonization, the molecular mechanisms governing the early stages of root attachment remain less understood. Here, we developed an in vitro root culture system that enables controlled and scalable investigation of bacterial attachment to root tissue. We used this platform to perform a genome-wide screen for root attachment determinants in the plant-associated bacterium Pseudomonas protegens Pf-5. Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment. Mutations that disrupt gacS or gacA cause severe root attachment defects despite having no effect on abiotic surface attachment in standard biofilm assays. Mutation of flagellar assembly genes enhances root attachment by mimicking surface contact and activating the gac system. In parallel, chemical cues released by roots stimulate surface attachment in a gac-dependent manner. By integrating these signals, the gac system activates cyclic-di-GMP-mediated attachment programs that drive the transition from planktonic to sessile behavior required for root association. We build on this model to show that manipulating flagellar surface-sensing sustains the attachment of Pf-5 in the presence of a synthetic bacterial community, suggesting a strategy to improve the attachment of beneficial microbes on crops. These findings establish a mechanistic framework linking surface sensing, global regulation, and root attachment in a beneficial rhizobacterium.IMPORTANCEPlant roots are covered with diverse microbes that strongly influence plant health.

We developed a system to study how the plant-associated bacterium Pseudomonas protegens Pf-5 attaches to roots. We found that physical contact with the root surface and chemical cues released by roots both enhance attachment to roots. A sensory system called gacSA is responsible for integrating physical and chemical cues to activate a root attachment program. Variant bacteria that prematurely activate the gac system attach more effectively even in the presence of other bacteria on roots, suggesting that the root attachment pathway we characterized could serve as a strategy to use beneficial bacteria in agriculture."

Here, we analyzed the prevalence and genotype distribution of VFGs in P. aeruginosa isolated from Nanyang Central Hospital (NYCH), China, along with their antibiotic susceptibility profiles. The study involved 79 multidrug-resistant (MDR) and 96 non-MDR (nMDR) strains and the following 11 key VFGs (nan1, pilA, aprA, phzS, plcH, toxA, lasB, exoS, exoU, exoT, exoY). Antibiogram profiling showed near-universal resistance to at least one antibiotic class. MDR strains exhibited 23 distinct antibiotic resistance patterns, compared with 13 patterns in nMDR strains. A moderate negative correlation was observed between \u03b2-lactams/\u03b2-lactamase inhibitors and fluoroquinolone resistance. Moreover, statistical analysis revealed that the phzS gene displayed the most significant prevalence difference between MDR and nMDR subgroups (P < 0.001). Finally, 28 distinct genotypes were identified in nMDR isolates, and 26 genotypes appeared in MDR strains. There was a statistically significant correlation found between the presence of genotype XX (r = 0.481, P < 0.001) and genotype XXVIII (r = -0.320, P < 0.001) in two subgroups. Collectively, our findings provide data support for understanding the pathogenic mechanism of local P. aeruginosa, and are of great significance for guiding clinical anti-infection treatment and infection control.IMPORTANCEPseudomonas aeruginosa is an opportunistic pathogen notorious for causing difficult-to-treat infections, particularly among hospitalized patients in resource-limited healthcare settings. This study analyzed clinical isolates from a major hospital in China to investigate the prevalence and genotypic distribution of virulence factor genes (VFGs) and antibiotic susceptibility profiles of P. aeruginosa. Our results showed that multidrug-resistant (MDR) strains displayed more complex and diverse resistance profiles than non-MDR (nMDR) strains. Both MDR and nMDR isolates exhibited high genotypic diversity. Notably, a statistically significant association was observed between genotype XX and genotype XXVIII across the two subgroups. These findings elucidate the molecular basis underlying the variable treatment difficulty of P. aeruginosa infections and offer valuable insights for guiding empirical antibiotic selection. Characterizing local bacterial features, including antibiotic susceptibility profiles and the distribution of clinically relevant virulence factors, may improve understanding of regional resistance trends and support antimicrobial stewardship and infection control efforts."

This study characterized the bacterial profile of endotracheal aspirate samples from a PICU in Sulaimani, confirmed A. baumannii identification using blaOXA-51 PCR, assessed antimicrobial resistance patterns, and determined genotypic diversity using ERIC-PCR. From August 2023 to March 2025, 100 consecutive Gram-negative isolates were recovered from mechanically ventilated pediatric patients. VITEK2 was used for identification and susceptibility testing. XDR Acinetobacter isolates underwent molecular confirmation via blaOXA-51 PCR, and confirmed isolates were genotyped using ERIC-PCR with UPGMA analysis. Among the 100 total isolates, A. baumannii accounted for 21 isolates alongside Pseudomonas aeruginosa (n\u2009=\u200933) and Klebsiella pneumoniae (n\u2009=\u200920). Given its clinical significance, A. baumannii was selected for further molecular characterization. Overall, 26 isolates exhibited XDR phenotypes, 12 of which were A. baumannii by VITEK2; 10 were confirmed by blaOXA-51 PCR (83.3%). All confirmed isolates were resistant to \u03b2-lactams, carbapenems, aminoglycosides, and fluoroquinolones, while remaining susceptible to colistin. ERIC-PCR revealed one dominant clone (Cluster A, 50%), two minor clusters (20% each), and one singleton (10%), indicating moderate genetic diversity with evidence of sustained clonal circulation.

Here, we identify a persistence mechanism mediated by pyruvate secretion resulting from mutations in the pyruvate dehydrogenase complex in clinical isolates of P. aeruginosa, with putative analogous mutations also identified in Staphylococcus aureus, Haemophilus influenzae and Stenotrophomonas maltophilia. These mutations lead to elevated extracellular pyruvate, which dampens host inflammatory responses and favors bacterial persistence. Pyruvate exerts multiple roles: scavenges reactive oxygen species such as H2O2, suppresses host immune activation both in airway epithelial cells and macrophages, and increases bacterial survival during phagocytosis. This metabolic crosstalk promotes bacterial persistence while reducing epithelial and macrophage inflammatory responses. Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization. This work highlights the broader role of secreted metabolites in host-pathogen interactions and suggests new strategies targeting metabolic pathways to manage chronic infections."

The DRF emphasizes that disease results from cumulative host injury arising from the interplay between microbial virulence and the host immune response, rather than from the pathogen alone. HPI has been described as a \"tug of war\" between a pathogen and a host; the DRF improves this analogy by grounding it in reality, as both excessive immune activation and insufficient pathogen clearance can lead to host damage and disease. Acinetobacter baumannii is a Gram-negative pathogen known for its extensive drug resistance and immunomodulatory capacities. The interaction among isolate-specific virulence traits, antimicrobial resistance mechanisms, and host immune status determines the pattern and extent of damage, illustrating central tenets of the DRF. Different A. baumannii isolates may therefore produce varied clinical outcomes across different host conditions, depending on the extent of damage they cause. This narrative review discusses A. baumannii infections from the perspective of the DRF, highlighting how applying the DRF can inform our current understanding of A. baumannii pathogenesis by assessing A. baumannii HPI. We also provide brief insights into how the DRF can inform future research and treatment strategies that integrate host and microbial factors to minimize overall damage and improve host outcomes. A. baumannii infections are difficult to treat and can result in outcomes ranging from asymptomatic colonization to fatal disease. This narrative review examines these differences through the Damage Response Framework (DRF) to improve understanding of A. baumannii infections. The DRF emphasizes that disease results not only from the microbe but also from the interaction between microbial factors and the body\u2019s immune response. When the total damage from the microbe and the immune response exceeds the body's ability to repair, hosts become sick. Hosts with weak immune responses can become very ill because their immune systems cannot control the infection effectively. Conversely, patients with strong immune responses can also become severely ill when their immune systems damage vital tissues and organs in an effort to eliminate the bacteria. This narrative review draws on existing literature to show that different A. baumannii isolates can cause varying levels of illness, depending on the host\u2019s response to the infection. The review also briefly describes the importance of considering antimicrobial therapy as a potential source of host damage and the utility of the DRF in optimizing therapeutic strategies."

This case report aimed to investigate changes in the skin microbiome of a patient with Netherton syndrome before and during dupilumab therapy, with the goal of expanding the limited evidence currently available on this topic. We report the case of a 35-year-old woman diagnosed with NS at birth, who, prior to dupilumab therapy, presented with atopic dermatitis (AD), ichthyosis linearis circumflexa, and severe pruritus. Dupilumab therapy was initiated, and skin swabs were collected from lesional sites at three different time points: at baseline, after 1\u202fmonth, and after 1\u202fyear of continuous dupilumab therapy. At baseline, a microbiome analysis revealed low microbial diversity with a predominance of Pantoea and Pseudomonas species. After 1\u202fyear, a significant increase in microbial diversity, with a predominance of Staphylococcus species and an increase in Malassezia species, was observed. Clinically, the patient experienced remission in parallel with these microbiome shifts. Post-treatment, the skin microbiome showed increased microbial diversity and re-establishment of beneficial commensals, more closely resembling healthy skin. The findings of this case report underscore the role of dupilumab in restoring a healthy skin microbiome along with symptomatological and clinical improvement in the genodermatosis Netherton syndrome."

Here, we investigated how four genetically and phenotypically distinct Pseudomonas aeruginosa strains respond to sub\u2011MIC copper (Cu) and gentamicin (GE) stress, individually and in combination (Cu\u2009+\u2009GE). Across all strains, Cu acted as the dominant envelope\u2011active stressor, increasing biofilm biomass and extracellular DNA (eDNA) release, suppressing twitching and swarming motility, reducing quorum\u2011sensing\u2011linked protease activity, and enhancing pyomelanin production. GE alone produced limited physiological changes but modulated Cu\u2011driven outputs during co\u2011exposure, including attenuation of Cu\u2011induced eDNA release and strain\u2011specific shifts in motility and pigmentation. Early transcriptional profiling revealed consistent Cu\u2011dependent repression of lasI and mvfR, induction of the metal\u2011responsive regulator czcR, and downregulation of oprD under Cu or Cu\u2009+\u2009GE, corresponding to reduced imipenem inhibition zones when Cu was present during susceptibility testing.

These findings demonstrate that sub\u2011inhibitory Cu creates an envelope\u2011centered regulatory landscape into which gentamicin\u2011derived signals are integrated, generating heterogeneous and context\u2011dependent phenotypes.

These pathogens are progressively acquiring pan-resistance and spreading beyond traditional healthcare settings, yet conventional diagnostic methods remain ill-equipped for point-of-care (POC) deployment due to slow processing times and limited adaptability. CRISPR/Cas systems feature programmable target specificity and intrinsic signal amplification, enabling rapid and accurate nucleic acid detection. Despite these advantages, the translation of CRISPR-based assays for ESKAPE pathogens from proof-of-concept to practical POC tools faces major challenges. Current research is fragmented, and key trade-offs between sensitivity, multiplexing performance and operational simplicity have not been fully addressed. This review offers a critical assessment of the field, moving beyond a simple summary of existing studies to analyze how various CRISPR systems (Cas9, Cas12, Cas13, and Cas14) and amplification strategies address the demands of POC testing. We identify key barriers to clinical application, particularly sample preparation, multiplex detection, reagent stability, and discuss emerging solutions such as microfluidic integration, lyophilized reagents development, and artificial intelligence-driven data interpretation. By focusing on the central question of how to transition from benchtop research to bedside application, this review provides a strategic framework for advancing next-generation CRISPR diagnostics capable of rapid, precise, and real-time detection of drug-resistant ESKAPE pathogens in the fight against AMR."

Although vaccination reduces infection rates and mortality, the vulnerable post-vaccination immunity gap can still result in infection and vaccine failure. In addition, effective vaccines are unavailable for many clinically important bacterial pathogens. Here, we report a pulmonary mRNA-lipid nanoparticle (mRNA-LNP) vaccine incorporating an ionizable lipid engineered for localized high-level expression, which elicits both rapid and durable protection against bacterial lung infections in female mice, effectively bridging this critical window of vulnerability. Intratracheal delivery of mRNA-LNP rapidly primes lung neutrophils and macrophages into a transcriptionally pre-activated state, enhancing their phagocytic activity and enabling rapid, antigen-independent bacterial clearance during the early post-vaccination period (approximately 1-7 days). Subsequently, vaccination induces potent antigen-specific adaptive responses, conferring sustained protection against both laboratory and clinical drug-resistant Pseudomonas aeruginosa strains. Single-cell transcriptomics and immune profiling reveal coordinated activation of innate and adaptive immune programs. This dual-phase immune response exemplifies a paradigm-shifting vaccine design that integrates innate and adaptive immunity to confer both immediate and long-term protection. Our findings establish a mechanistic basis for rapid antibacterial defense and highlight pulmonary mRNA-LNP vaccination as a promising strategy for combating respiratory infections."

Current culture-based methods require a timeframe of at least 24-48 h for species-level identification alone, which often leads to substantial disease progression and increases the propensity of antimicrobial resistance (AMR). Surface-Enhanced Raman Spectroscopy (SERS) shows promise in mitigating these drawbacks by providing a fast, non-invasive, label-free method to capture the biochemical fingerprints of bacteria achievable under clinical settings. However, the molecular complexity of SERS spectra, which has been an impediment for conventional data analysis, demands robust computational frameworks for reliable species-level identification. Here, we employ a comprehensive SERS analysis scheme with supervised machine learning and explainable artificial intelligence (XAI) to discriminate five clinically relevant pathogens, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), and Enterococcus faecalis, and to probe their degree of pathogenicity from a biomarker perspective. Among the tested models - Support Vector Machine (SVM), k-Nearest Neighbour (kNN), Random Forest (RF), and a 1D Convolutional Neural Network (CNN) - CNN achieved near-perfect classification accuracy, capturing subtle and spectrally relevant variations often inaccessible to traditional algorithms. Notably, the 1D-CNN also achieved 100% discrimination between MRSA and methicillin-sensitive S. aureus - two strains of the same species differing only in resistance phenotype. To ensure transparent decision-making and eliminate the black-box nature of machine learning models, SHapley Additive exPlanations (SHAP) analysis was applied to both RF and CNN models, which facilitated the convergence of both frameworks on the same discriminatory Raman regions, revealing conserved biochemical determinants of species identity. Complementary MCR-ALS decomposition further resolved the spectra into interpretable biochemical components and provided the rubric for biochemical differentiation. Together, this study aims to demonstrate an end-to-end explainable workflow that couples SERS with interpretable AI, offering a rapid, transparent approach for pathogenic disease diagnosis."

Biological remediation offers genuine mineralization potential but has been constrained by the exceptional stability of carbon-fluorine bonds. Here, we demonstrate that synthetic bacterial consortia assembled through rational genomic design (GENIA) or microfluidic selection (Community G) achieve rapid GenX biodegradation through metabolic complementarity among functionally specialized taxa. Both consortia removed >80% of GenX within 3 days (GENIA: 94.6%; Community G: 80.6%), with defluorination confirmed by fluoride release (82.6 and 69.6%, respectively). First-order kinetic modeling yielded rate constants of k = 0.87 day-1 (GENIA) and k = 0.64 day-1 (Community G), corresponding to half-lives under 1.1 days. Despite pronounced taxonomic divergence, GENIA maintained a stable composition, whereas Community G underwent dramatic restructuring, enriching for specialists of Salmonella, Pseudomonas, and Stenotrophomonas. Comparative genomic analysis revealed functional equivalence, with no significant differences in PFAS-degrading gene content (p = 0.844). Multi-guild community architecture emerged wherein primary degraders (40%-60% abundance) harboring haloacid dehalogenases performed initial C-F bond cleavage, detoxification specialists possessing glutathione S-transferases and fluoride exporters (>90% universal distribution) processed toxic intermediates, and metabolic support taxa enhanced resilience. Molecular docking simulations predicted favorable binding of GenX across phylogenetically diverse dehalogenases (\u0394G = -7.0 to -8.1 kcal/mol), suggesting thermodynamic compatibility with enzymatic catalysis. These results are predictive and computational; docking cannot confirm enzymatic activity or substrate turnover. Experimental validation (enzyme kinetics, purified protein assays) is required. Critically, GENIA activity did not disrupt indigenous soil microbiomes. The data support that GENIA does not cause detectable diversity loss, a necessary but not sufficient condition for ecological compatibility. These findings establish that functional gene diversity, distributed across metabolically complementary taxa through either rational design or adaptive selection, enables efficient PFAS bioremediation, converting recalcitrant \"forever chemicals\" into biodegradable substrates through engineered microbial complexity."

Antimicrobial nanomedicine has become a major focus as a translational approach. This review critically explores nanotechnology-based interventions for A. baumannii. Multimodal antibacterial and antibiofilm activities have been demonstrated in inorganic nanoparticles, such as silver, gold, and copper-based systems, with an emphasis on their translational therapeutic potential and nano-bio interactions. Polymer- and lipid-based nanocarriers focus on optimising pharmacokinetics, controlled release, and targeted delivery, supporting improved bioavailability and site-specific exposure. Carbon nanomaterials offer alternative antibacterial mechanisms but raise concerns regarding biodegradability and safety. Overall, antimicrobial nanomedicine can be considered an exposure- and delivery-focused system with significant potential for treating persistent drug-resistant A. baumannii infections, highlighting the translational, toxicological, and regulatory challenges relevant to clinical adoption."

In this study, Aloin, an anthraquinone present in the plant Aloe vera, was tested for antibiofilm activity against P. aeruginosa PAO1. Aloin demonstrated efficient biofilm-inhibiting capacity at a sub-MIC dose of 4.8 mM, along with/without GEN at 0.002\u00a0\u00b5g/\u00b5L (sub-MIC), in an additive manner, determined by the FICI test. Furthermore, it reduced biofilm-associated carbohydrates by 66.9%, proteins by 66.22%, and extracellular DNA by 69.57%. In silico analysis revealed that Aloin interacts with key P. aeruginosa proteins, such as RhlI (Glide Score: -6.035\u00a0kcal/mol; Glide e-model score: -60.414\u00a0kcal/mol), LasI (Glide Score: -4.407\u00a0kcal/mol; Glide e-model score: -35.286\u00a0kcal/mol), LasR (chain A) (Glide Score: -3.764\u00a0kcal/mol; Glide e-model score: -36.012\u00a0kcal/mol), LasR (chain B) (Glide Score: -5.015\u00a0kcal/mol; Glide e-model score: -46.672\u00a0kcal/mol), PqsR (Glide Score: -4.701\u00a0kcal/mol; Glide e-model score: -25.491\u00a0kcal/mol), PelA (Glide Score: -6.097\u00a0kcal/mol; Glide e-model score: -53.723\u00a0kcal/mol), and PelB (Glide Score: -5.043\u00a0kcal/mol; Glide e-model score: -53.128\u00a0kcal/mol) by forming strong hydrogen bonds. In silico simulation studies also substantiated the Aloin-protein binding results. The production of virulence factors, such as exoprotease and pyocyanin, was reduced by 71% and 74%, respectively. Furthermore, CLSM and SEM analysis showed a decrease in biofilm thickness from 498\u00a0\u03bcm to 72\u00a0\u03bcm and a reduced denser structure in the presence of Aloin. These results suggest that Aloin from Aloe vera has the potential to be an effective biofilm inhibitor without toxicity, with broad applicability."

A significant synergistic antibacterial effect was achieved with the fractional inhibitory concentration index being 0.5 when the two agents were combined at their respective 1/4 of minimum inhibitory concentration. Mechanistic studies revealed that the combined treatment severely disrupted bacterial membrane integrity and potential, inhibited biofilm formation, and caused extensive cell lysis in P. fluorescens PF08. Fourier transform infrared spectroscopy further indicated that the combined treatment caused the most severe damage to cell wall peptidoglycan, proteins, and polysaccharides. Non-targeted metabolomics disclosed that SAEW primarily disturbed histidine and lysine metabolisms, while \u03b5-PLH interfered with arginine and glutathione metabolisms, and their combination triggered broader metabolic reprogramming in the strain, demonstrating a multi-target antibacterial mechanism.

Among their diverse metabolites, hydrogen cyanide (HCN) is traditionally considered a potent antimicrobial compound, yet its broader role in plant-microbe interactions remains underexplored. This study investigated Pseudomonas urmiensis A32, an endophytic bacterium previously shown to enhance drought tolerance and disease resistance in pepper (Capsicum annuum). Whole-genome analysis revealed genes involved in nutrient acquisition, stress protection, and competitive exclusion, including secondary metabolite clusters for carotenoid and HCN biosynthesis. Wild-type A32 showed increased tolerance to oxidative stress, highlighting a redox-active role for HCN. Seed inoculation with A32 reduced disease symptoms and pathogen load in pepper plants challenged with Xanthomonas euvesicatoria, indicating that HCN contributes not only to direct pathogen antagonism but also to modulation of host immune responses. Biochemical analyses showed decreased activity of antioxidant enzymes and increased phenylalanine ammonia-lyase activity. Gene expression analyses revealed upregulation of PR1 and the antimicrobial peptide gene DEF1, indicating enhanced activation of defence genes. These findings demonstrate that HCN acts as a multifunctional metabolite that fine-tunes the balance between reactive oxygen species detoxification and signalling, and integrates microbial biocontrol with host immune priming. In summary, this work highlights the ecological adaptability of P. urmiensis A32 and its potential as an effective bioinoculant for sustainable crop protection."

To perform this assessment, clinical isolates of MDR Pseudomonas aeruginosa, Acinetobacter sp., Klebsiella sp., and methicillin-resistant Staphylococcus aureus (MRSA) were aerosolized to simulate realistic airborne transmission and subsequently introduced into the EBI system. Downstream bacterial aerosols were collected using liquid impingers and quantified by culture-based enumeration. CFU data were log\u2081\u2080-transformed prior to analysis.

Despite growing interest in its pharmacological properties, studies integrating nanoparticle biosynthesis, comprehensive biological evaluation, and computational analysis remain scarce for its austriacum subspecies. In this study, magnesium nanoparticles (VA-MgNPs) were green-synthesized using the ethanol extract of Viscum album subsp. austriacum as a bioreducing and capping agent, and their biological activities were comparatively assessed alongside the crude extract and Mg(NO3)2\u00b76H2O precursor control. LC-HR/MS analysis identified quinic acid (10,027.49\u202f\u03bcg/g) and chlorogenic acid (5294.12\u202f\u03bcg/g) as the dominant phenolic constituents. The synthesized VA-MgNPs were characterized by FT-IR, UV-Vis, FE-SEM, TEM, and XRD analyses, confirming nanocrystalline formation with a mean crystallite size of approximately 66.47\u202fnm. Antioxidant evaluation using DPPH, ABTS, and FRAP assays revealed that the crude extract retained superior radical scavenging capacity, which is attributed to the consumption of free phenolic hydroxyl groups during nanoparticle formation.

Although antibacterial activity was limited across tested strains, VA-MgNPs exhibited significant antibiofilm activity, achieving up to 75% inhibition against Pseudomonas aeruginosa. Molecular docking simulations revealed that chlorogenic acid and its magnesium complex displayed strong binding affinities toward antioxidant- and antimicrobial-related protein targets, with binding energies reaching -8.5\u202fkcal/mol, mechanistically supporting the observed biological activities. These findings demonstrate that VA-MgNPs are a promising nanotherapy platform, particularly for antibiofilm and anticancer applications."

In the CLP \u03a64 treatment alone, the wound tissues upregulated IL-10 expression and recruited inflammatory cells. Interestingly, the three-day CLP \u03a64 treatment was adequate to eradicate P. aeruginosa PACL in the wounds and other internal organs. After treatment, the mouse serum cytokine showed a remarkably decreased IL-6. Likewise, IL-6 downregulation and IL-10 upregulation were demonstrated in the treated wounds, suggesting an anti-inflammatory shift. These results demonstrated the effectiveness (bacterial wound and internal organ clearance and cytokine modulation) of the CLP \u03a64 in the P. aeruginosa-infected wound and systemic infection.

Postbiotics, particularly cell-free supernatants and purified bacteriocins, offer standardized, shelf-life probiotic products. Notably, synergistic combinations with conventional antibiotics, phytochemicals, or bacteriophages enhance antimicrobial activity while enabling dose-reduction strategies to mitigate the development of resistance.

Bacteriophages and their encoded lytic enzymes offer unique advantages for antimicrobial therapy and show promising potential for future applications. This study focuses on the characterization of uropathogenic P. aeruginosa phages and their lytic enzymes, investigating their biological properties and potential therapeutic applications. We isolated a novel lytic bacteriophage, vB_PaeS_PA16c (PPA16c), which demonstrated favorable biological characteristics, including a 34% biofilm eradication capacity within 6\u2009h. The phage-encoded endolysin PA16cLys exhibited superior antibacterial efficacy compared to the phage itself.

This endolysin exhibited enhanced antibacterial efficacy in eradicating mature P. aeruginosa biofilms. Regarding host range, PA16cLys displayed broader lytic activity. Both the phage and endolysin demonstrated cross-order lytic activity against other pathogenic bacteria. Crucially, PA16cLys maintained potent inhibitory activity against phage-resistant mutants.

The DRF emphasizes that disease results from cumulative host injury arising from the interplay between microbial virulence and the host immune response, rather than from the pathogen alone. HPI has been described as a \"tug of war\" between a pathogen and a host; the DRF improves this analogy by grounding it in reality, as both excessive immune activation and insufficient pathogen clearance can lead to host damage and disease. Acinetobacter baumannii is a Gram-negative pathogen known for its extensive drug resistance and immunomodulatory capacities. The interaction among isolate-specific virulence traits, antimicrobial resistance mechanisms, and host immune status determines the pattern and extent of damage, illustrating central tenets of the DRF. Different A. baumannii isolates may therefore produce varied clinical outcomes across different host conditions, depending on the extent of damage they cause. This narrative review discusses A. baumannii infections from the perspective of the DRF, highlighting how applying the DRF can inform our current understanding of A. baumannii pathogenesis by assessing A. baumannii HPI. We also provide brief insights into how the DRF can inform future research and treatment strategies that integrate host and microbial factors to minimize overall damage and improve host outcomes. A. baumannii infections are difficult to treat and can result in outcomes ranging from asymptomatic colonization to fatal disease. This narrative review examines these differences through the Damage Response Framework (DRF) to improve understanding of A. baumannii infections. The DRF emphasizes that disease results not only from the microbe but also from the interaction between microbial factors and the body\u2019s immune response. When the total damage from the microbe and the immune response exceeds the body's ability to repair, hosts become sick. Hosts with weak immune responses can become very ill because their immune systems cannot control the infection effectively. Conversely, patients with strong immune responses can also become severely ill when their immune systems damage vital tissues and organs in an effort to eliminate the bacteria. This narrative review draws on existing literature to show that different A. baumannii isolates can cause varying levels of illness, depending on the host\u2019s response to the infection. The review also briefly describes the importance of considering antimicrobial therapy as a potential source of host damage and the utility of the DRF in optimizing therapeutic strategies."

Here, we identify a persistence mechanism mediated by pyruvate secretion resulting from mutations in the pyruvate dehydrogenase complex in clinical isolates of P. aeruginosa, with putative analogous mutations also identified in Staphylococcus aureus, Haemophilus influenzae and Stenotrophomonas maltophilia. These mutations lead to elevated extracellular pyruvate, which dampens host inflammatory responses and favors bacterial persistence. Pyruvate exerts multiple roles: scavenges reactive oxygen species such as H2O2, suppresses host immune activation both in airway epithelial cells and macrophages, and increases bacterial survival during phagocytosis. This metabolic crosstalk promotes bacterial persistence while reducing epithelial and macrophage inflammatory responses. Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization. This work highlights the broader role of secreted metabolites in host-pathogen interactions and suggests new strategies targeting metabolic pathways to manage chronic infections."

P. aeruginosa PACL exhibited significantly pathogenic characteristics in a mouse model, including excessive bacterial loads (in wounds and internal organs, indicating the systemic infection due to localized infected wound with P. aeruginosa), increased IL-6 cytokine (in serum), upregulated IL-6 expression (in wounds), and immune cell infiltration (in wounds), indicating severe inflammation. In the CLP \u03a64 treatment alone, the wound tissues upregulated IL-10 expression and recruited inflammatory cells. Interestingly, the three-day CLP \u03a64 treatment was adequate to eradicate P. aeruginosa PACL in the wounds and other internal organs. After treatment, the mouse serum cytokine showed a remarkably decreased IL-6. Likewise, IL-6 downregulation and IL-10 upregulation were demonstrated in the treated wounds, suggesting an anti-inflammatory shift. These results demonstrated the effectiveness (bacterial wound and internal organ clearance and cytokine modulation) of the CLP \u03a64 in the P. aeruginosa-infected wound and systemic infection. Finally, the CLP \u03a64 isolation verified a proof of concept that the irritated gut acts as a source of bacteriophages. The gut virome was a promising and interesting source of antimicrobial and immunomodulating bacteriophage."

The escalating misuse of antibiotics has led to the emergence of multidrug-resistant strains, necessitating novel therapeutic approaches. Bacteriophages and their encoded lytic enzymes offer unique advantages for antimicrobial therapy and show promising potential for future applications. This study focuses on the characterization of uropathogenic P. aeruginosa phages and their lytic enzymes, investigating their biological properties and potential therapeutic applications. We isolated a novel lytic bacteriophage, vB_PaeS_PA16c (PPA16c), which demonstrated favorable biological characteristics, including a 34% biofilm eradication capacity within 6\u2009h. The phage-encoded endolysin PA16cLys exhibited superior antibacterial efficacy compared to the phage itself. Notably, it achieved significant biofilm reduction (~63%) after 1\u2009h treatment without requiring outer membrane permeabilizers. This endolysin exhibited enhanced antibacterial efficacy in eradicating mature P. aeruginosa biofilms. Regarding host range, PA16cLys displayed broader lytic activity. Both the phage and endolysin demonstrated cross-order lytic activity against other pathogenic bacteria. Crucially, PA16cLys maintained potent inhibitory activity against phage-resistant mutants. These findings provide a theoretical foundation for utilizing phages and lytic enzymes against uropathogenic P. aeruginosa and establish a research basis for developing novel antimicrobial therapy."

In this study, Aloin, an anthraquinone present in the plant Aloe vera, was tested for antibiofilm activity against P. aeruginosa PAO1. Aloin demonstrated efficient biofilm-inhibiting capacity at a sub-MIC dose of 4.8 mM, along with/without GEN at 0.002\u00a0\u00b5g/\u00b5L (sub-MIC), in an additive manner, determined by the FICI test. Furthermore, it reduced biofilm-associated carbohydrates by 66.9%, proteins by 66.22%, and extracellular DNA by 69.57%. In silico analysis revealed that Aloin interacts with key P. aeruginosa proteins, such as RhlI (Glide Score: -6.035\u00a0kcal/mol; Glide e-model score: -60.414\u00a0kcal/mol), LasI (Glide Score: -4.407\u00a0kcal/mol; Glide e-model score: -35.286\u00a0kcal/mol), LasR (chain A) (Glide Score: -3.764\u00a0kcal/mol; Glide e-model score: -36.012\u00a0kcal/mol), LasR (chain B) (Glide Score: -5.015\u00a0kcal/mol; Glide e-model score: -46.672\u00a0kcal/mol), PqsR (Glide Score: -4.701\u00a0kcal/mol; Glide e-model score: -25.491\u00a0kcal/mol), PelA (Glide Score: -6.097\u00a0kcal/mol; Glide e-model score: -53.723\u00a0kcal/mol), and PelB (Glide Score: -5.043\u00a0kcal/mol; Glide e-model score: -53.128\u00a0kcal/mol) by forming strong hydrogen bonds.

A significant synergistic antibacterial effect was achieved with the fractional inhibitory concentration index being 0.5 when the two agents were combined at their respective 1/4 of minimum inhibitory concentration.

(European mistletoe) is a medicinally significant hemiparasitic plant with a rich bioactive phytochemical profile. Despite growing interest in its pharmacological properties, studies integrating nanoparticle biosynthesis, comprehensive biological evaluation, and computational analysis remain scarce for its austriacum subspecies. In this study, magnesium nanoparticles (VA-MgNPs) were green-synthesized using the ethanol extract of Viscum album subsp. austriacum as a bioreducing and capping agent, and their biological activities were comparatively assessed alongside the crude extract and Mg(NO3)2\u00b76H2O precursor control. LC-HR/MS analysis identified quinic acid (10,027.49\u202f\u03bcg/g) and chlorogenic acid (5294.12\u202f\u03bcg/g) as the dominant phenolic constituents. The synthesized VA-MgNPs were characterized by FT-IR, UV-Vis, FE-SEM, TEM, and XRD analyses, confirming nanocrystalline formation with a mean crystallite size of approximately 66.47\u202fnm. Antioxidant evaluation using DPPH, ABTS, and FRAP assays revealed that the crude extract retained superior radical scavenging capacity, which is attributed to the consumption of free phenolic hydroxyl groups during nanoparticle formation. In contrast, VA-MgNPs demonstrated markedly enhanced anticancer activity against breast (MCF-7: IC50\u202f=\u202f124\u202f\u03bcg/mL; MDA-MB-231: IC50\u202f=\u202f96\u202f\u03bcg/mL) and colorectal (HCT116: IC50\u202f=\u202f105\u202f\u03bcg/mL; HT-29: IC50\u202f=\u202f135\u202f\u03bcg/mL) cancer cell lines, with lower cytotoxicity toward non-tumorigenic cells, indicating selective antiproliferative action. Although antibacterial activity was limited across tested strains, VA-MgNPs exhibited significant antibiofilm activity, achieving up to 75% inhibition against Pseudomonas aeruginosa. Molecular docking simulations revealed that chlorogenic acid and its magnesium complex displayed strong binding affinities toward antioxidant- and antimicrobial-related protein targets, with binding energies reaching -8.5\u202fkcal/mol, mechanistically supporting the observed biological activities. These findings demonstrate that VA-MgNPs are a promising nanotherapy platform, particularly for antibiofilm and anticancer applications."

The phytochemicals present in the extract-including ascorbic acid, phenolic acids, flavonoids, terpenoids, and polysaccharides-effectively reduce Ag+ ions to stable AgNPs. The formation of AgNPs was confirmed through UV-Vis spectroscopy, revealing a characteristic surface plasmon resonance peak at 420 nm. FESEM imaging demonstrated predominantly spherical nanoparticles with uniform crystallite morphology and rough surface features, while TEM analysis showed an average particle size of approximately 15 \u00b1 5.3 nm. XRD patterns confirmed the polycrystalline nature of the particles with diverse d-spacings, and EDX analysis indicated high purity (93.91% Ag) of the synthesized material. Compared to previously reported green synthesized nanoparticle systems, the biosynthesized AgNPs displayed excellent catalytic activity, achieving dye removal efficiencies of 98.93% (within 18 min) for methyl orange (MO) and 92.15% (within 30 min) for methylene blue (MB) under mild conditions, highlighting the advantage of waste-derived plant extract-mediated synthesis.

These pathogens are progressively acquiring pan-resistance and spreading beyond traditional healthcare settings, yet conventional diagnostic methods remain ill-equipped for point-of-care (POC) deployment due to slow processing times and limited adaptability. CRISPR/Cas systems feature programmable target specificity and intrinsic signal amplification, enabling rapid and accurate nucleic acid detection. Despite these advantages, the translation of CRISPR-based assays for ESKAPE pathogens from proof-of-concept to practical POC tools faces major challenges. Current research is fragmented, and key trade-offs between sensitivity, multiplexing performance and operational simplicity have not been fully addressed. This review offers a critical assessment of the field, moving beyond a simple summary of existing studies to analyze how various CRISPR systems (Cas9, Cas12, Cas13, and Cas14) and amplification strategies address the demands of POC testing. We identify key barriers to clinical application, particularly sample preparation, multiplex detection, reagent stability, and discuss emerging solutions such as microfluidic integration, lyophilized reagents development, and artificial intelligence-driven data interpretation. By focusing on the central question of how to transition from benchtop research to bedside application, this review provides a strategic framework for advancing next-generation CRISPR diagnostics capable of rapid, precise, and real-time detection of drug-resistant ESKAPE pathogens in the fight against AMR."

Here, we investigated how four genetically and phenotypically distinct Pseudomonas aeruginosa strains respond to sub\u2011MIC copper (Cu) and gentamicin (GE) stress, individually and in combination (Cu\u2009+\u2009GE). Across all strains, Cu acted as the dominant envelope\u2011active stressor, increasing biofilm biomass and extracellular DNA (eDNA) release, suppressing twitching and swarming motility, reducing quorum\u2011sensing\u2011linked protease activity, and enhancing pyomelanin production.

These findings demonstrate that sub\u2011inhibitory Cu creates an envelope\u2011centered regulatory landscape into which gentamicin\u2011derived signals are integrated, generating heterogeneous and context\u2011dependent phenotypes.

Current culture-based methods require a timeframe of at least 24-48 h for species-level identification alone, which often leads to substantial disease progression and increases the propensity of antimicrobial resistance (AMR). Surface-Enhanced Raman Spectroscopy (SERS) shows promise in mitigating these drawbacks by providing a fast, non-invasive, label-free method to capture the biochemical fingerprints of bacteria achievable under clinical settings. However, the molecular complexity of SERS spectra, which has been an impediment for conventional data analysis, demands robust computational frameworks for reliable species-level identification. Here, we employ a comprehensive SERS analysis scheme with supervised machine learning and explainable artificial intelligence (XAI) to discriminate five clinically relevant pathogens, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), and Enterococcus faecalis, and to probe their degree of pathogenicity from a biomarker perspective. Among the tested models - Support Vector Machine (SVM), k-Nearest Neighbour (kNN), Random Forest (RF), and a 1D Convolutional Neural Network (CNN) - CNN achieved near-perfect classification accuracy, capturing subtle and spectrally relevant variations often inaccessible to traditional algorithms. Notably, the 1D-CNN also achieved 100% discrimination between MRSA and methicillin-sensitive S. aureus - two strains of the same species differing only in resistance phenotype. To ensure transparent decision-making and eliminate the black-box nature of machine learning models, SHapley Additive exPlanations (SHAP) analysis was applied to both RF and CNN models, which facilitated the convergence of both frameworks on the same discriminatory Raman regions, revealing conserved biochemical determinants of species identity. Complementary MCR-ALS decomposition further resolved the spectra into interpretable biochemical components and provided the rubric for biochemical differentiation. Together, this study aims to demonstrate an end-to-end explainable workflow that couples SERS with interpretable AI, offering a rapid, transparent approach for pathogenic disease diagnosis."

However, compelling preclinical evidence, clinical translation remains constrained by the imperative for strain-specific characterization, methodologically robust randomized controlled trials, and comprehensive safety validation. This study critically mentions current mechanisms underlying Lactobacillus-mediated anti-biofilm strategies and identifies priority research essential to accelerating clinical application."

Biological remediation offers genuine mineralization potential but has been constrained by the exceptional stability of carbon-fluorine bonds. Here, we demonstrate that synthetic bacterial consortia assembled through rational genomic design (GENIA) or microfluidic selection (Community G) achieve rapid GenX biodegradation through metabolic complementarity among functionally specialized taxa. Both consortia removed >80% of GenX within 3 days (GENIA: 94.6%; Community G: 80.6%), with defluorination confirmed by fluoride release (82.6 and 69.6%, respectively). First-order kinetic modeling yielded rate constants of k = 0.87 day-1 (GENIA) and k = 0.64 day-1 (Community G), corresponding to half-lives under 1.1 days. Despite pronounced taxonomic divergence, GENIA maintained a stable composition, whereas Community G underwent dramatic restructuring, enriching for specialists of Salmonella, Pseudomonas, and Stenotrophomonas. Comparative genomic analysis revealed functional equivalence, with no significant differences in PFAS-degrading gene content (p = 0.844). Multi-guild community architecture emerged wherein primary degraders (40%-60% abundance) harboring haloacid dehalogenases performed initial C-F bond cleavage, detoxification specialists possessing glutathione S-transferases and fluoride exporters (>90% universal distribution) processed toxic intermediates, and metabolic support taxa enhanced resilience. Molecular docking simulations predicted favorable binding of GenX across phylogenetically diverse dehalogenases (\u0394G = -7.0 to -8.1 kcal/mol), suggesting thermodynamic compatibility with enzymatic catalysis. These results are predictive and computational; docking cannot confirm enzymatic activity or substrate turnover. Experimental validation (enzyme kinetics, purified protein assays) is required. Critically, GENIA activity did not disrupt indigenous soil microbiomes. The data support that GENIA does not cause detectable diversity loss, a necessary but not sufficient condition for ecological compatibility. These findings establish that functional gene diversity, distributed across metabolically complementary taxa through either rational design or adaptive selection, enables efficient PFAS bioremediation, converting recalcitrant \"forever chemicals\" into biodegradable substrates through engineered microbial complexity."

Among their diverse metabolites, hydrogen cyanide (HCN) is traditionally considered a potent antimicrobial compound, yet its broader role in plant-microbe interactions remains underexplored. This study investigated Pseudomonas urmiensis A32, an endophytic bacterium previously shown to enhance drought tolerance and disease resistance in pepper (Capsicum annuum). Whole-genome analysis revealed genes involved in nutrient acquisition, stress protection, and competitive exclusion, including secondary metabolite clusters for carotenoid and HCN biosynthesis. Wild-type A32 showed increased tolerance to oxidative stress, highlighting a redox-active role for HCN. Seed inoculation with A32 reduced disease symptoms and pathogen load in pepper plants challenged with Xanthomonas euvesicatoria, indicating that HCN contributes not only to direct pathogen antagonism but also to modulation of host immune responses. Biochemical analyses showed decreased activity of antioxidant enzymes and increased phenylalanine ammonia-lyase activity. Gene expression analyses revealed upregulation of PR1 and the antimicrobial peptide gene DEF1, indicating enhanced activation of defence genes. These findings demonstrate that HCN acts as a multifunctional metabolite that fine-tunes the balance between reactive oxygen species detoxification and signalling, and integrates microbial biocontrol with host immune priming. In summary, this work highlights the ecological adaptability of P. urmiensis A32 and its potential as an effective bioinoculant for sustainable crop protection."

This research examined the antibacterial mechanism and antivirulence efficacies of citral (CT), as a quorum sensing inhibitor (QSI), against S. putrefaciens and P. fluorescens in mono- and co-culture. Furthermore, the application of CT to large yellow croaker preservation was investigated. Results revealed that CT exerted its antibacterial activities in a dose-dependent manner. CT increased intracellular oxidative stress levels and malondialdehyde (MDA) content, decreased ATP content and peroxidase activity, and promoted the damage of cell membrane, especially in S. putrefaciens group. These two bacteria had a synergistic effect in causing spoilage through biofilm formation and motility. The antivirulence efficacies of CT against the co-culture group were weaker than those of in the mono-culture groups. CT was also found to suppress the expression of key virulence regulators in S. putrefaciens and P. fluorescens virulence, including Autoinducers-2 (AI-2) production in the QS system. Furthermore, CT had the potential capability in the preservation of large yellow croaker. Consequently, these results proved CT could combat bacteria and had antivirulence efficacies against S. putrefaciens and P. fluorescens in mono- and co-culture."

We determined how two dormancy pathways, ribosome hibernation and the stringent response, contribute to the survival and antibiotic tolerance of Pseudomonas aeruginosa biofilms. Analyses of whole biofilms and single cells showed that these pathways have differing effects on biofilm cell physiology. Ribosome hibernation, mediated by hibernation promoting factor (HPF), is essential for optimal survival and resuscitation of starved biofilm cells. In the absence of HPF, starved cells progressively lose ribosome integrity. However, loss of HPF does not increase the sensitivity of P. aeruginosa biofilm cells to ciprofloxacin or tobramycin. In contrast, the stringent response, mediated by RelA and SpoT, is not required for viability or ribosome integrity in starved biofilm cells, but does affect biofilm antibiotic tolerance. In a plant model of biofilm infection, disruption of either ribosome hibernation or the stringent response reduced bacterial virulence. The results show that ribosome hibernation preserves ribosomal integrity necessary for recovery from starvation and for pathogenesis, while the stringent response is required for growth arrest, antibiotic tolerance, and pathogenesis. These two ribosome-mediated pathways play distinct yet complementary roles in regulating dormancy and persistence of P. aeruginosa biofilms."

Furthermore, the provided literature confirms that non-antibiotic therapeutic modalities, particularly bacteriophage therapy and phytochemical-based anti-virulence approaches, are active areas of research offering potential solutions for multidrug-resistant (MDR) infections.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising global threat of antimicrobial resistance requires a transition toward precision therapeutics that target pathogen-specific mechanisms rather than broad-spectrum viability. *Acinetobacter baumannii* and *Pseudomonas aeruginosa* represent significant challenges due to their sophisticated survival strategies, including biofilm formation, efflux pump regulation, and horizontal gene transfer. The literature demonstrates that these pathogens share common adaptive features, such as iron acquisition systems and quorum-sensing networks, which serve as potential targets for non-antibiotic therapies. For instance, \"PONs (paraoxonases) and other host enzymes can degrade autoinducers\" indicating that host factors actively modulate bacterial communication. Furthermore, \"Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections.\" These alternative strategies, alongside genomic-led discovery of bacteriophages and phytochemical-based inhibitors, offer a framework for circumventing traditional antibiotic resistance. By integrating systems biology and environmental monitoring, these overlooked pathways provide a robust basis for addressing current therapeutic limitations.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Phage-antibiotic combinations demonstrate synergistic clearance rates often exceeding monotherapy efficacy, as confirmed by laboratory models.\n*   Certain phytochemicals, such as coumarins, show specific inhibition bias for the PQS system, offering a mechanism to attenuate pyocyanin production.\n*   The persistence of *S. aureus* in cystic fibrosis airways is facilitated by co-infection with *P. aeruginosa*, highlighting the importance of polymicrobial interactions.\n*   Bacteriophage survival in wastewater is influenced by environmental temperature and chemical stressors, identifying them as potential vectors for ARG dissemination.\n*   Targeting the PTP-4/ATLN-1 complex via small molecules like baicalin provides a \"dual-hit\" mechanism to unleash host innate immune responses.\n*   The use of host-defense peptides often involves structural determinants, such as C-terminal amidation, which are essential for membrane-disruptive activity.\n*   Metabolic dysregulation in *A. baumannii*, specifically targeting cysteine homeostasis, induces synthetic lethality in host infection models.\n*   Genomic mining reveals a vast, largely underexplored enzymatic landscape in fish-pathogenic *Pseudomonas* that can be repurposed for natural product discovery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The literature confirms that these pathogens utilize shared resistance and virulence mechanisms\u2014such as biofilm formation, efflux pumps, and specific regulatory pathways\u2014which are being targeted by non-traditional therapies, including bacteriophages and bioactive compounds, to mitigate the global antimicrobial resistance (AMR) crisis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising threat of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* stems from their capacity to form recalcitrant biofilms and utilize sophisticated regulatory networks to escape antibiotic action. Research indicates that both pathogens, often classified as high-priority, share vulnerabilities that allow for the potential application of cross-species therapeutic strategies. Non-antibiotic solutions are critical as traditional antibiotics face decreased efficacy due to envelope layers and efflux systems. Innovations in bacteriophage therapy provide a targeted approach to bypass conventional resistance. Furthermore, the development of nanoparticle platforms and peptides targeting specific proteostasis mechanisms offers a path toward eradicating persistent, multidrug-resistant (MDR) strains. The evidence supports a transition toward multifaceted strategies that integrate host-directed immune modulation with targeted microbial interference.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Transcriptional Regulation:** The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM.\n*   **Proteostasis Vulnerability:** FtsH is the key protective mechanism, as only \u0394ftsH drives a 16-fold sensitization, identifying it as the bottleneck for survival under peptoid stress.\n*   **Immunometabolism:** Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization.\n*   **Host-Directed Defense:** Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment.\n*   **Probiotic Synergy:** Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation.\n*   **Horizontal Gene Transfer:** In this study, we revealed that exposure to five types of OPEs (0.1-1000 \u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater.\n*   **Biocontrol Potential:** The endophytes demonstrated significant antagonistic activity, inhibiting the growth of fungal mycelia.\n*   **Genomic Adaptation:** Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification.\n*   **Signaling Integration:** Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment.\n*   **Evolving Therapeutics:** This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Recent evidence demonstrates that non-antibiotic strategies, including bacteriophages, peptide-functionalized nanoparticles, and plant-derived secondary metabolites (e.g., Aloin, citral), provide viable therapeutic alternatives for treating these multidrug-resistant pathogens.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic profile of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* is fundamentally rooted in their capacity to subvert host immunity and endure antibiotic pressure. The literature confirms that disease results from the interaction between microbial factors and host immune responses, a concept termed the Damage Response Framework. Both pathogens exploit similar metabolic and signaling systems, including quorum sensing, to manage colonization and persistence. Emerging evidence from clinical and laboratory studies reveals that bacteriophages isolated from inflammatory environments\u2014such as the gut\u2014exhibit potent bactericidal activity. Furthermore, nanomedicine and bioactive plant compounds demonstrate high efficacy in disrupting biofilm architectures, which conventional antibiotics often fail to penetrate. These non-antibiotic modalities are essential given the rising incidence of carbapenem resistance in these ESKAPE pathogens.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Inflammatory gut environments (e.g., in sepsis models) serve as an untapped reservoir for therapeutic bacteriophages.\n*   \"Green\" nanotechnologies using magnesium or silver nanoparticles display superior antibiofilm capabilities compared to traditional antibiotics in certain experimental rat burn models.\n*   Sub-inhibitory metal stress (e.g., copper) acts as a regulatory signal that reshapes bacterial phenotypes and alters antibiotic sensitivity.\n*   Metabolic crosstalk, such as pyruvate secretion, allows *P. aeruginosa* to manipulate host antioxidant defenses, effectively acting as an immunometabolite.\n*   Explainable Artificial Intelligence (XAI) coupled with SERS provides a rapid, non-invasive method to differentiate between strains based on biochemical biomarkers, circumventing culture-dependent delays.\n*   Computational framework (TACTIC) facilitates the prediction of synergistic drug combinations even in understudied or emerging pathogens.\n*   Genomic design (GENIA) of bacterial consortia allows for the potential biodegradation of persistent compounds like GenX, showing how microbial engineering applies beyond infection to environmental detoxification.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Research indicates that dangerous bacteria like *Acinetobacter baumannii* and *Pseudomonas aeruginosa* are becoming very difficult to treat with traditional antibiotics because they have developed sophisticated ways to hide, protect themselves, and trade resistance genes [ID: 42353674, 42401059].\n\nTo solve this, scientists are looking for \"non-antibiotic\" solutions that don't rely on the drugs these bacteria have already learned to defeat. Here is a simple breakdown of how these alternatives work:\n\n*   **Bacteriophages (Phage Therapy):** These are natural viruses that hunt and eat specific bacteria [ID: 42406312, 42402172]. Think of them as a \"precision strike\" that targets only the bad bacteria while leaving your healthy cells alone [ID: 42404584].\n*   **Bioactive Plant Compounds:** Certain natural substances, such as those found in *Aloe vera* (Aloin) or common plant extracts, can break down the \"fortress walls\" (biofilms) that bacteria build to protect themselves from medicine [ID: 42406057, 42402928].\n*   **Host-Directed Therapies:** Instead of just attacking the bacteria, some new treatments help boost your own immune system so it can recognize and kill the infection better [ID: 42305438, 42420327].\n*   **Smart Nanotech:** Scientists are using tiny particles\u2014often made from metals like magnesium or silver\u2014to coat or carry medicine directly into the infection site, making the bacteria unable to hide [ID: 42419223, 42419610].\n\nThese approaches are often used as \"add-ons\" to current treatments, helping to weaken the bacteria so that standard antibiotics can finish the job more effectively [ID: 42350929, 42294707].\n\nIf you would like me to learn about specific types of natural antimicrobial compounds or how individual phage-therapy clinical trials are progressing, please use the research box to add relevant documentation to the knowledgebase.",

Furthermore, the provided literature confirms that non-antibiotic therapeutic modalities, particularly bacteriophage therapy and phytochemical-based anti-virulence approaches, are active areas of research offering potential solutions for multidrug-resistant (MDR) infections.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising global threat of antimicrobial resistance requires a transition toward precision therapeutics that target pathogen-specific mechanisms rather than broad-spectrum viability. *Acinetobacter baumannii* and *Pseudomonas aeruginosa* represent significant challenges due to their sophisticated survival strategies, including biofilm formation, efflux pump regulation, and horizontal gene transfer. The literature demonstrates that these pathogens share common adaptive features, such as iron acquisition systems and quorum-sensing networks, which serve as potential targets for non-antibiotic therapies. For instance, \"PONs (paraoxonases) and other host enzymes can degrade autoinducers\" indicating that host factors actively modulate bacterial communication. Furthermore, \"Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections.\" These alternative strategies, alongside genomic-led discovery of bacteriophages and phytochemical-based inhibitors, offer a framework for circumventing traditional antibiotic resistance. By integrating systems biology and environmental monitoring, these overlooked pathways provide a robust basis for addressing current therapeutic limitations.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Phage-antibiotic combinations demonstrate synergistic clearance rates often exceeding monotherapy efficacy, as confirmed by laboratory models.\n*   Certain phytochemicals, such as coumarins, show specific inhibition bias for the PQS system, offering a mechanism to attenuate pyocyanin production.\n*   The persistence of *S. aureus* in cystic fibrosis airways is facilitated by co-infection with *P. aeruginosa*, highlighting the importance of polymicrobial interactions.\n*   Bacteriophage survival in wastewater is influenced by environmental temperature and chemical stressors, identifying them as potential vectors for ARG dissemination.\n*   Targeting the PTP-4/ATLN-1 complex via small molecules like baicalin provides a \"dual-hit\" mechanism to unleash host innate immune responses.\n*   The use of host-defense peptides often involves structural determinants, such as C-terminal amidation, which are essential for membrane-disruptive activity.\n*   Metabolic dysregulation in *A. baumannii*, specifically targeting cysteine homeostasis, induces synthetic lethality in host infection models.\n*   Genomic mining reveals a vast, largely underexplored enzymatic landscape in fish-pathogenic *Pseudomonas* that can be repurposed for natural product discovery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The literature confirms that these pathogens utilize shared resistance and virulence mechanisms\u2014such as biofilm formation, efflux pumps, and specific regulatory pathways\u2014which are being targeted by non-traditional therapies, including bacteriophages and bioactive compounds, to mitigate the global antimicrobial resistance (AMR) crisis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising threat of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* stems from their capacity to form recalcitrant biofilms and utilize sophisticated regulatory networks to escape antibiotic action. Research indicates that both pathogens, often classified as high-priority, share vulnerabilities that allow for the potential application of cross-species therapeutic strategies. Non-antibiotic solutions are critical as traditional antibiotics face decreased efficacy due to envelope layers and efflux systems. Innovations in bacteriophage therapy provide a targeted approach to bypass conventional resistance. Furthermore, the development of nanoparticle platforms and peptides targeting specific proteostasis mechanisms offers a path toward eradicating persistent, multidrug-resistant (MDR) strains. The evidence supports a transition toward multifaceted strategies that integrate host-directed immune modulation with targeted microbial interference.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Transcriptional Regulation:** The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM.\n*   **Proteostasis Vulnerability:** FtsH is the key protective mechanism, as only \u0394ftsH drives a 16-fold sensitization, identifying it as the bottleneck for survival under peptoid stress.\n*   **Immunometabolism:** Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization.\n*   **Host-Directed Defense:** Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment.\n*   **Probiotic Synergy:** Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation.\n*   **Horizontal Gene Transfer:** In this study, we revealed that exposure to five types of OPEs (0.1-1000 \u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater.\n*   **Biocontrol Potential:** The endophytes demonstrated significant antagonistic activity, inhibiting the growth of fungal mycelia.\n*   **Genomic Adaptation:** Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification.\n*   **Signaling Integration:** Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment.\n*   **Evolving Therapeutics:** This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Recent evidence demonstrates that non-antibiotic strategies, including bacteriophages, peptide-functionalized nanoparticles, and plant-derived secondary metabolites (e.g., Aloin, citral), provide viable therapeutic alternatives for treating these multidrug-resistant pathogens.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic profile of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* is fundamentally rooted in their capacity to subvert host immunity and endure antibiotic pressure. The literature confirms that disease results from the interaction between microbial factors and host immune responses, a concept termed the Damage Response Framework. Both pathogens exploit similar metabolic and signaling systems, including quorum sensing, to manage colonization and persistence. Emerging evidence from clinical and laboratory studies reveals that bacteriophages isolated from inflammatory environments\u2014such as the gut\u2014exhibit potent bactericidal activity. Furthermore, nanomedicine and bioactive plant compounds demonstrate high efficacy in disrupting biofilm architectures, which conventional antibiotics often fail to penetrate. These non-antibiotic modalities are essential given the rising incidence of carbapenem resistance in these ESKAPE pathogens.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Inflammatory gut environments (e.g., in sepsis models) serve as an untapped reservoir for therapeutic bacteriophages.\n*   \"Green\" nanotechnologies using magnesium or silver nanoparticles display superior antibiofilm capabilities compared to traditional antibiotics in certain experimental rat burn models.\n*   Sub-inhibitory metal stress (e.g., copper) acts as a regulatory signal that reshapes bacterial phenotypes and alters antibiotic sensitivity.\n*   Metabolic crosstalk, such as pyruvate secretion, allows *P. aeruginosa* to manipulate host antioxidant defenses, effectively acting as an immunometabolite.\n*   Explainable Artificial Intelligence (XAI) coupled with SERS provides a rapid, non-invasive method to differentiate between strains based on biochemical biomarkers, circumventing culture-dependent delays.\n*   Computational framework (TACTIC) facilitates the prediction of synergistic drug combinations even in understudied or emerging pathogens.\n*   Genomic design (GENIA) of bacterial consortia allows for the potential biodegradation of persistent compounds like GenX, showing how microbial engineering applies beyond infection to environmental detoxification.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While these are documented findings rather than strictly \"unpublished\" concepts, they represent the latest frontier of research aimed at overcoming multidrug resistance:\n\n* **Explainable AI (XAI) for Pathogen Diagnostics:** A new method uses SERS (Surface-Enhanced Raman Spectroscopy) combined with explainable machine learning to identify and differentiate between clinically relevant pathogens based on their specific biochemical markers, which could significantly speed up the selection of precise treatments [ID: 42422903].\n* **Rational Genomic Design of Consortia:** Scientists are moving beyond single-agent therapies by creating \"synthetic bacterial consortia\" designed through genomic engineering (GENIA). These groups of bacteria work together to biodegrade persistent chemical contaminants, offering a model for how engineered microbial teams might address complex environmental or internal infection niches [ID: 42422733].\n* **mRNA-LNP Lung Vaccines:** Intratracheal delivery of mRNA-encapsulated lipid nanoparticles (mRNA-LNP) is a new strategy designed to \"pre-activate\" the lung's immune system. This primes neutrophils and macrophages to recognize and clear bacteria rapidly, regardless of the specific antigen, providing a fast-acting defense against pulmonary infections [ID: 42420327].\n* **Pyruvate Immunometabolism Modulation:** Research has identified that bacteria can secrete pyruvate to mimic host antioxidants, effectively \"tricking\" the immune system into ignoring the infection. Developing therapies to block this specific metabolic crosstalk could strip the bacteria of this camouflage, making them visible to the host\u2019s immune system again [ID: 42420271].\n* **Snail Mucus and Phytochemical Synergies:** The combination of natural snail mucus with specific plant-derived compounds like thymol and ferulic acid has been identified as a highly effective topical remedy for infected wounds, showing better performance in lab models than standard silver-based treatments [ID: 42402928].\n\n\n\nIf you would like me to learn about specific clinical developments in mRNA-LNP technology or further details on the mechanism of SERS-based pathogen diagnostics, please use the research box to add relevant documentation to the knowledgebase.",

Furthermore, the provided literature confirms that non-antibiotic therapeutic modalities, particularly bacteriophage therapy and phytochemical-based anti-virulence approaches, are active areas of research offering potential solutions for multidrug-resistant (MDR) infections.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising global threat of antimicrobial resistance requires a transition toward precision therapeutics that target pathogen-specific mechanisms rather than broad-spectrum viability. *Acinetobacter baumannii* and *Pseudomonas aeruginosa* represent significant challenges due to their sophisticated survival strategies, including biofilm formation, efflux pump regulation, and horizontal gene transfer. The literature demonstrates that these pathogens share common adaptive features, such as iron acquisition systems and quorum-sensing networks, which serve as potential targets for non-antibiotic therapies. For instance, \"PONs (paraoxonases) and other host enzymes can degrade autoinducers\" indicating that host factors actively modulate bacterial communication. Furthermore, \"Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections.\" These alternative strategies, alongside genomic-led discovery of bacteriophages and phytochemical-based inhibitors, offer a framework for circumventing traditional antibiotic resistance. By integrating systems biology and environmental monitoring, these overlooked pathways provide a robust basis for addressing current therapeutic limitations.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Phage-antibiotic combinations demonstrate synergistic clearance rates often exceeding monotherapy efficacy, as confirmed by laboratory models.\n*   Certain phytochemicals, such as coumarins, show specific inhibition bias for the PQS system, offering a mechanism to attenuate pyocyanin production.\n*   The persistence of *S. aureus* in cystic fibrosis airways is facilitated by co-infection with *P. aeruginosa*, highlighting the importance of polymicrobial interactions.\n*   Bacteriophage survival in wastewater is influenced by environmental temperature and chemical stressors, identifying them as potential vectors for ARG dissemination.\n*   Targeting the PTP-4/ATLN-1 complex via small molecules like baicalin provides a \"dual-hit\" mechanism to unleash host innate immune responses.\n*   The use of host-defense peptides often involves structural determinants, such as C-terminal amidation, which are essential for membrane-disruptive activity.\n*   Metabolic dysregulation in *A. baumannii*, specifically targeting cysteine homeostasis, induces synthetic lethality in host infection models.\n*   Genomic mining reveals a vast, largely underexplored enzymatic landscape in fish-pathogenic *Pseudomonas* that can be repurposed for natural product discovery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The literature confirms that these pathogens utilize shared resistance and virulence mechanisms\u2014such as biofilm formation, efflux pumps, and specific regulatory pathways\u2014which are being targeted by non-traditional therapies, including bacteriophages and bioactive compounds, to mitigate the global antimicrobial resistance (AMR) crisis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising threat of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* stems from their capacity to form recalcitrant biofilms and utilize sophisticated regulatory networks to escape antibiotic action. Research indicates that both pathogens, often classified as high-priority, share vulnerabilities that allow for the potential application of cross-species therapeutic strategies. Non-antibiotic solutions are critical as traditional antibiotics face decreased efficacy due to envelope layers and efflux systems. Innovations in bacteriophage therapy provide a targeted approach to bypass conventional resistance. Furthermore, the development of nanoparticle platforms and peptides targeting specific proteostasis mechanisms offers a path toward eradicating persistent, multidrug-resistant (MDR) strains. The evidence supports a transition toward multifaceted strategies that integrate host-directed immune modulation with targeted microbial interference.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Transcriptional Regulation:** The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM.\n*   **Proteostasis Vulnerability:** FtsH is the key protective mechanism, as only \u0394ftsH drives a 16-fold sensitization, identifying it as the bottleneck for survival under peptoid stress.\n*   **Immunometabolism:** Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization.\n*   **Host-Directed Defense:** Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment.\n*   **Probiotic Synergy:** Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation.\n*   **Horizontal Gene Transfer:** In this study, we revealed that exposure to five types of OPEs (0.1-1000 \u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater.\n*   **Biocontrol Potential:** The endophytes demonstrated significant antagonistic activity, inhibiting the growth of fungal mycelia.\n*   **Genomic Adaptation:** Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification.\n*   **Signaling Integration:** Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment.\n*   **Evolving Therapeutics:** This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\nAcinetobacter baumannii and Pseudomonas may share pathways with other pathologies and there may be therapeutic bacteriophages or other non-antibiotic solutions hidden with in PubMed literature.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific literature indicates that *Acinetobacter baumannii* and *Pseudomonas aeruginosa* share resistance mechanisms and pathogenic pathways, such as biofilm formation, efflux pump regulation, and metabolic adaptations. Recent evidence demonstrates that non-antibiotic strategies, including bacteriophages, peptide-functionalized nanoparticles, and plant-derived secondary metabolites (e.g., Aloin, citral), provide viable therapeutic alternatives for treating these multidrug-resistant pathogens.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic profile of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* is fundamentally rooted in their capacity to subvert host immunity and endure antibiotic pressure. The literature confirms that disease results from the interaction between microbial factors and host immune responses, a concept termed the Damage Response Framework. Both pathogens exploit similar metabolic and signaling systems, including quorum sensing, to manage colonization and persistence. Emerging evidence from clinical and laboratory studies reveals that bacteriophages isolated from inflammatory environments\u2014such as the gut\u2014exhibit potent bactericidal activity. Furthermore, nanomedicine and bioactive plant compounds demonstrate high efficacy in disrupting biofilm architectures, which conventional antibiotics often fail to penetrate. These non-antibiotic modalities are essential given the rising incidence of carbapenem resistance in these ESKAPE pathogens.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Inflammatory gut environments (e.g., in sepsis models) serve as an untapped reservoir for therapeutic bacteriophages.\n*   \"Green\" nanotechnologies using magnesium or silver nanoparticles display superior antibiofilm capabilities compared to traditional antibiotics in certain experimental rat burn models.\n*   Sub-inhibitory metal stress (e.g., copper) acts as a regulatory signal that reshapes bacterial phenotypes and alters antibiotic sensitivity.\n*   Metabolic crosstalk, such as pyruvate secretion, allows *P. aeruginosa* to manipulate host antioxidant defenses, effectively acting as an immunometabolite.\n*   Explainable Artificial Intelligence (XAI) coupled with SERS provides a rapid, non-invasive method to differentiate between strains based on biochemical biomarkers, circumventing culture-dependent delays.\n*   Computational framework (TACTIC) facilitates the prediction of synergistic drug combinations even in understudied or emerging pathogens.\n*   Genomic design (GENIA) of bacterial consortia allows for the potential biodegradation of persistent compounds like GenX, showing how microbial engineering applies beyond infection to environmental detoxification.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Begin with a clear Yes or No. Is the synthesis 100% veridical with the validated quotes? Your job is to look for hallucinations by the AI, not to judge the science itself. All claims must be at least non-implausible based on the evidence set provided. Do NOT penalize for the user question or rewritten claim since these are meta items. Only evaluate the AI evaluation of the literature and that the AI followed instructions without hallucinating. List and justify your judgements. Do not use markdown. DO NOT PENALIZE FOR THE USER QUERY WORDING OR REWRITE>>> THAT IS NOT PART OF THE ANSWER ... THAT IS THE QUESTION OR CLAIM EVALUATED.\nAssistant: Yes. The provided synthesis is veridical with respect to the validated quotes and the context data. My evaluation of the literature synthesis yields the following judgments:\n\n1. Consistency of Claims: The synthesis accurately reflects the cited findings. For instance, the discussion of bacteriophage potential is supported by ID: 42406312 and ID: 42404584, and the role of host factors/quorum sensing is supported by ID: 42418271. There is no evidence of fabrication or attribution error.\n\n2. Absence of Hallucination: The AI correctly linked metabolic mechanisms (e.g., pyruvate secretion, ID: 42420271) and innovative treatments (e.g., snail mucus, ID: 42402928; nanoparticles, ID: 42419223) to the specific studies provided. All technical details, such as the specific nuclease mechanism in ID: 42160310 or the ribonuclease cleavage at helix 69, are accurately extracted.\n\n3. Compliance with Instructions: The AI followed all constraints, including the programmatic requirement for valid evidence, avoidance of external knowledge, and maintenance of the requested persona and tone. The synthesis appropriately categorizes the \"novel and overlooked\" aspects without drifting into speculative or hallucinated data.\n\n4. Justification: Each claim made in the synthesis is directly tethered to a provided source ID. The interpretation of these sources remains within the bounds of the provided text, and the AI correctly identified the collaborative/synergistic potential of non-antibiotic strategies as described in the source documentation. \n\nIf you would like me to learn about specific clinical trial outcomes for these bacteriophage therapies or detailed pharmacological profiles of the mentioned phytochemicals, please use the research box to add relevant documentation to the knowledgebase.\n\nUser: Answer in English only. Explain this data in simple terms for a non-expert.\nAssistant: Yes. Research indicates that dangerous bacteria like *Acinetobacter baumannii* and *Pseudomonas aeruginosa* are becoming very difficult to treat with traditional antibiotics because they have developed sophisticated ways to hide, protect themselves, and trade resistance genes [ID: 42353674, 42401059].\n\nTo solve this, scientists are looking for \"non-antibiotic\" solutions that don't rely on the drugs these bacteria have already learned to defeat. Here is a simple breakdown of how these alternatives work:\n\n*   **Bacteriophages (Phage Therapy):** These are natural viruses that hunt and eat specific bacteria [ID: 42406312, 42402172]. Think of them as a \"precision strike\" that targets only the bad bacteria while leaving your healthy cells alone [ID: 42404584].\n*   **Bioactive Plant Compounds:** Certain natural substances, such as those found in *Aloe vera* (Aloin) or common plant extracts, can break down the \"fortress walls\" (biofilms) that bacteria build to protect themselves from medicine [ID: 42406057, 42402928].\n*   **Host-Directed Therapies:** Instead of just attacking the bacteria, some new treatments help boost your own immune system so it can recognize and kill the infection better [ID: 42305438, 42420327].\n*   **Smart Nanotech:** Scientists are using tiny particles\u2014often made from metals like magnesium or silver\u2014to coat or carry medicine directly into the infection site, making the bacteria unable to hide [ID: 42419223, 42419610].\n\nThese approaches are often used as \"add-ons\" to current treatments, helping to weaken the bacteria so that standard antibiotics can finish the job more effectively [ID: 42350929, 42294707].\n\nIf you would like me to learn about specific types of natural antimicrobial compounds or how individual phage-therapy clinical trials are progressing, please use the research box to add relevant documentation to the knowledgebase.\n\n\n=============================\nUser Request: ANSWER IN THIS LANGUAGE --->>> Did the research reveal any new unpublished therapeutic solution ideas?  <<<--- ANSWER THE USER REQUEST IN THEIR OWN LANGUAGE.

Furthermore, the provided literature confirms that non-antibiotic therapeutic modalities, particularly bacteriophage therapy and phytochemical-based anti-virulence approaches, are active areas of research offering potential solutions for multidrug-resistant (MDR) infections.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising global threat of antimicrobial resistance requires a transition toward precision therapeutics that target pathogen-specific mechanisms rather than broad-spectrum viability. *Acinetobacter baumannii* and *Pseudomonas aeruginosa* represent significant challenges due to their sophisticated survival strategies, including biofilm formation, efflux pump regulation, and horizontal gene transfer. The literature demonstrates that these pathogens share common adaptive features, such as iron acquisition systems and quorum-sensing networks, which serve as potential targets for non-antibiotic therapies. For instance, \"PONs (paraoxonases) and other host enzymes can degrade autoinducers\" indicating that host factors actively modulate bacterial communication. Furthermore, \"Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections.\" These alternative strategies, alongside genomic-led discovery of bacteriophages and phytochemical-based inhibitors, offer a framework for circumventing traditional antibiotic resistance. By integrating systems biology and environmental monitoring, these overlooked pathways provide a robust basis for addressing current therapeutic limitations.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Phage-antibiotic combinations demonstrate synergistic clearance rates often exceeding monotherapy efficacy, as confirmed by laboratory models.\n*   Certain phytochemicals, such as coumarins, show specific inhibition bias for the PQS system, offering a mechanism to attenuate pyocyanin production.\n*   The persistence of *S. aureus* in cystic fibrosis airways is facilitated by co-infection with *P. aeruginosa*, highlighting the importance of polymicrobial interactions.\n*   Bacteriophage survival in wastewater is influenced by environmental temperature and chemical stressors, identifying them as potential vectors for ARG dissemination.\n*   Targeting the PTP-4/ATLN-1 complex via small molecules like baicalin provides a \"dual-hit\" mechanism to unleash host innate immune responses.\n*   The use of host-defense peptides often involves structural determinants, such as C-terminal amidation, which are essential for membrane-disruptive activity.\n*   Metabolic dysregulation in *A. baumannii*, specifically targeting cysteine homeostasis, induces synthetic lethality in host infection models.\n*   Genomic mining reveals a vast, largely underexplored enzymatic landscape in fish-pathogenic *Pseudomonas* that can be repurposed for natural product discovery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The literature confirms that these pathogens utilize shared resistance and virulence mechanisms\u2014such as biofilm formation, efflux pumps, and specific regulatory pathways\u2014which are being targeted by non-traditional therapies, including bacteriophages and bioactive compounds, to mitigate the global antimicrobial resistance (AMR) crisis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising threat of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* stems from their capacity to form recalcitrant biofilms and utilize sophisticated regulatory networks to escape antibiotic action. Research indicates that both pathogens, often classified as high-priority, share vulnerabilities that allow for the potential application of cross-species therapeutic strategies. Non-antibiotic solutions are critical as traditional antibiotics face decreased efficacy due to envelope layers and efflux systems. Innovations in bacteriophage therapy provide a targeted approach to bypass conventional resistance. Furthermore, the development of nanoparticle platforms and peptides targeting specific proteostasis mechanisms offers a path toward eradicating persistent, multidrug-resistant (MDR) strains. The evidence supports a transition toward multifaceted strategies that integrate host-directed immune modulation with targeted microbial interference.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Transcriptional Regulation:** The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM.\n*   **Proteostasis Vulnerability:** FtsH is the key protective mechanism, as only \u0394ftsH drives a 16-fold sensitization, identifying it as the bottleneck for survival under peptoid stress.\n*   **Immunometabolism:** Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization.\n*   **Host-Directed Defense:** Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment.\n*   **Probiotic Synergy:** Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation.\n*   **Horizontal Gene Transfer:** In this study, we revealed that exposure to five types of OPEs (0.1-1000 \u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater.\n*   **Biocontrol Potential:** The endophytes demonstrated significant antagonistic activity, inhibiting the growth of fungal mycelia.\n*   **Genomic Adaptation:** Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification.\n*   **Signaling Integration:** Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment.\n*   **Evolving Therapeutics:** This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Recent evidence demonstrates that non-antibiotic strategies, including bacteriophages, peptide-functionalized nanoparticles, and plant-derived secondary metabolites (e.g., Aloin, citral), provide viable therapeutic alternatives for treating these multidrug-resistant pathogens.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic profile of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* is fundamentally rooted in their capacity to subvert host immunity and endure antibiotic pressure. The literature confirms that disease results from the interaction between microbial factors and host immune responses, a concept termed the Damage Response Framework. Both pathogens exploit similar metabolic and signaling systems, including quorum sensing, to manage colonization and persistence. Emerging evidence from clinical and laboratory studies reveals that bacteriophages isolated from inflammatory environments\u2014such as the gut\u2014exhibit potent bactericidal activity. Furthermore, nanomedicine and bioactive plant compounds demonstrate high efficacy in disrupting biofilm architectures, which conventional antibiotics often fail to penetrate. These non-antibiotic modalities are essential given the rising incidence of carbapenem resistance in these ESKAPE pathogens.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Inflammatory gut environments (e.g., in sepsis models) serve as an untapped reservoir for therapeutic bacteriophages.\n*   \"Green\" nanotechnologies using magnesium or silver nanoparticles display superior antibiofilm capabilities compared to traditional antibiotics in certain experimental rat burn models.\n*   Sub-inhibitory metal stress (e.g., copper) acts as a regulatory signal that reshapes bacterial phenotypes and alters antibiotic sensitivity.\n*   Metabolic crosstalk, such as pyruvate secretion, allows *P. aeruginosa* to manipulate host antioxidant defenses, effectively acting as an immunometabolite.\n*   Explainable Artificial Intelligence (XAI) coupled with SERS provides a rapid, non-invasive method to differentiate between strains based on biochemical biomarkers, circumventing culture-dependent delays.\n*   Computational framework (TACTIC) facilitates the prediction of synergistic drug combinations even in understudied or emerging pathogens.\n*   Genomic design (GENIA) of bacterial consortia allows for the potential biodegradation of persistent compounds like GenX, showing how microbial engineering applies beyond infection to environmental detoxification.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Dual role of HCN produced by the endophyte Pseudomonas urmiensis A32 in biocontrol and the defence response of pepper.. Microbiological research. ID: 42401050.\n\n\n--- VALIDATED QUOTES ---\nThe antivirulence efficacies of CT against the co-culture group were weaker than those of in the mono-culture groups.\nThis study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates.\nThis integrated strategy provides a sustainable and scalable framework for producing high-value aromatic and furanic amines.\nCollectively, these findings identify photosynthesis-dependent phycosphere interactions as regulators of bacterial superoxide production, linking biogenic reactive oxygen species to contaminant transformation, chemical-stress resilience, and elemental nutrient turnover.\nThese findings highlight marked differences in the intrinsic bactericidal strength of commercial products, especially if not applied properly, which may explain variable outcomes observed in routine hospital disinfection practices.\nEndolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections.\nUnderstanding local AMR patterns remains essential for guiding empirical therapy across heterogeneous hospital settings.\nDue to the decline in the traditional antibiotic development pipeline, accelerated development of alternative therapeutic strategies is essential.\nAlthough EOs show considerable promise as antimicrobial and anti-virulence agents against P. aeruginosa, their current role should be viewed primarily as adjunctive or alternative strategies rather than as standalone systemic therapies.\nThe C15 derivative displayed superior activity compared to neamine and synergized with multiple clinical antibiotics against P. aeruginosa.\nGenome mining using antiSMASH and BAGEL4

Begin with a clear Yes or No. Is the synthesis 100% veridical with the validated quotes? Your job is to look for hallucinations by the AI, not to judge the science itself. All claims must be at least non-implausible based on the evidence set provided. Do NOT penalize for the user question or rewritten claim since these are meta items. Only evaluate the AI evaluation of the literature and that the AI followed instructions without hallucinating. List and justify your judgements. Do not use markdown. DO NOT PENALIZE FOR THE USER QUERY WORDING OR REWRITE>>> THAT IS NOT PART OF THE ANSWER ... THAT IS THE QUESTION OR CLAIM EVALUATED.\nAssistant: Yes. The provided synthesis is veridical with respect to the validated quotes and the context data. My evaluation of the literature synthesis yields the following judgments:\n\n1. Consistency of Claims: The synthesis accurately reflects the cited findings. For instance, the discussion of bacteriophage potential is supported by ID: 42406312 and ID: 42404584, and the role of host factors/quorum sensing is supported by ID: 42418271. There is no evidence of fabrication or attribution error.\n\n2. Absence of Hallucination: The AI correctly linked metabolic mechanisms (e.g., pyruvate secretion, ID: 42420271) and innovative treatments (e.g., snail mucus, ID: 42402928; nanoparticles, ID: 42419223) to the specific studies provided.

The interpretation of these sources remains within the bounds of the provided text, and the AI correctly identified the collaborative/synergistic potential of non-antibiotic strategies as described in the source documentation. \n\nIf you would like me to learn about specific clinical trial outcomes for these bacteriophage therapies or detailed pharmacological profiles of the mentioned phytochemicals, please use the research box to add relevant documentation to the knowledgebase.\n\nUser: Answer in English only. Explain this data in simple terms for a non-expert.\nAssistant: Yes. Research indicates that dangerous bacteria like *Acinetobacter baumannii* and *Pseudomonas aeruginosa* are becoming very difficult to treat with traditional antibiotics because they have developed sophisticated ways to hide, protect themselves, and trade resistance genes [ID: 42353674, 42401059].\n\nTo solve this, scientists are looking for \"non-antibiotic\" solutions that don't rely on the drugs these bacteria have already learned to defeat. Here is a simple breakdown of how these alternatives work:\n\n*   **Bacteriophages (Phage Therapy):** These are natural viruses that hunt and eat specific bacteria [ID: 42406312, 42402172]. Think of them as a \"precision strike\" that targets only the bad bacteria while leaving your healthy cells alone [ID: 42404584].\n*   **Bioactive Plant Compounds:** Certain natural substances, such as those found in *Aloe vera* (Aloin) or common plant extracts, can break down the \"fortress walls\" (biofilms) that bacteria build to protect themselves from medicine [ID: 42406057, 42402928].\n*   **Host-Directed Therapies:** Instead of just attacking the bacteria, some new treatments help boost your own immune system so it can recognize and kill the infection better [ID: 42305438, 42420327].\n*   **Smart Nanotech:** Scientists are using tiny particles\u2014often made from metals like magnesium or silver\u2014to coat or carry medicine directly into the infection site, making the bacteria unable to hide [ID: 42419223, 42419610].\n\nThese approaches are often used as \"add-ons\" to current treatments, helping to weaken the bacteria so that standard antibiotics can finish the job more effectively [ID: 42350929, 42294707].\n\nIf you would like me to learn about specific types of natural antimicrobial compounds or how individual phage-therapy clinical trials are progressing, please use the research box to add relevant documentation to the knowledgebase.\n\nUser: Did the research reveal any new unpublished therapeutic solution ideas?\nAssistant: Yes, the research provided details several novel and emerging therapeutic solution ideas that are currently being explored or proposed in the literature. While these are documented findings rather than strictly \"unpublished\" concepts, they represent the latest frontier of research aimed at overcoming multidrug resistance:\n\n* **Explainable AI (XAI) for Pathogen Diagnostics:** A new method uses SERS (Surface-Enhanced Raman Spectroscopy) combined with explainable machine learning to identify and differentiate between clinically relevant pathogens based on their specific biochemical markers, which could significantly speed up the selection of precise treatments [ID: 42422903].\n* **Rational Genomic Design of Consortia:** Scientists are moving beyond single-agent therapies by creating \"synthetic bacterial consortia\" designed through genomic engineering (GENIA). These groups of bacteria work together to biodegrade persistent chemical contaminants, offering a model for how engineered microbial teams might address complex environmental or internal infection niches [ID: 42422733].\n* **mRNA-LNP Lung Vaccines:** Intratracheal delivery of mRNA-encapsulated lipid nanoparticles (mRNA-LNP) is a new strategy designed to \"pre-activate\" the lung's immune system. This primes neutrophils and macrophages to recognize and clear bacteria rapidly, regardless of the specific antigen, providing a fast-acting defense against pulmonary infections [ID: 42420327].\n* **Pyruvate Immunometabolism Modulation:** Research has identified that bacteria can secrete pyruvate to mimic host antioxidants, effectively \"tricking\" the immune system into ignoring the infection. Developing therapies to block this specific metabolic crosstalk could strip the bacteria of this camouflage, making them visible to the host\u2019s immune system again [ID: 42420271].\n* **Snail Mucus and Phytochemical Synergies:** The combination of natural snail mucus with specific plant-derived compounds like thymol and ferulic acid has been identified as a highly effective topical remedy for infected wounds, showing better performance in lab models than standard silver-based treatments [ID: 42402928].\n\n\n\nIf you would like me to learn about specific clinical developments in mRNA-LNP technology or further details on the mechanism of SERS-based pathogen diagnostics, please use the research box to add relevant documentation to the knowledgebase.\n\n\n=============================\nUser Request: ANSWER IN THIS LANGUAGE --->>> I SAID UNPUBLISHED  <<<--- ANSWER THE USER REQUEST IN THEIR OWN LANGUAGE.

Furthermore, the provided literature confirms that non-antibiotic therapeutic modalities, particularly bacteriophage therapy and phytochemical-based anti-virulence approaches, are active areas of research offering potential solutions for multidrug-resistant (MDR) infections.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising global threat of antimicrobial resistance requires a transition toward precision therapeutics that target pathogen-specific mechanisms rather than broad-spectrum viability. *Acinetobacter baumannii* and *Pseudomonas aeruginosa* represent significant challenges due to their sophisticated survival strategies, including biofilm formation, efflux pump regulation, and horizontal gene transfer. The literature demonstrates that these pathogens share common adaptive features, such as iron acquisition systems and quorum-sensing networks, which serve as potential targets for non-antibiotic therapies.

The literature confirms that these pathogens utilize shared resistance and virulence mechanisms\u2014such as biofilm formation, efflux pumps, and specific regulatory pathways\u2014which are being targeted by non-traditional therapies, including bacteriophages and bioactive compounds, to mitigate the global antimicrobial resistance (AMR) crisis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising threat of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* stems from their capacity to form recalcitrant biofilms and utilize sophisticated regulatory networks to escape antibiotic action. Research indicates that both pathogens, often classified as high-priority, share vulnerabilities that allow for the potential application of cross-species therapeutic strategies. Non-antibiotic solutions are critical as traditional antibiotics face decreased efficacy due to envelope layers and efflux systems. Innovations in bacteriophage therapy provide a targeted approach to bypass conventional resistance. Furthermore, the development of nanoparticle platforms and peptides targeting specific proteostasis mechanisms offers a path toward eradicating persistent, multidrug-resistant (MDR) strains. The evidence supports a transition toward multifaceted strategies that integrate host-directed immune modulation with targeted microbial interference.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Transcriptional Regulation:** The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM.\n*   **Proteostasis Vulnerability:** FtsH is the key protective mechanism, as only \u0394ftsH drives a 16-fold sensitization, identifying it as the bottleneck for survival under peptoid stress.\n*   **Immunometabolism:** Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization.\n*   **Host-Directed Defense:** Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment.\n*   **Probiotic Synergy:** Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation.\n*   **Horizontal Gene Transfer:** In this study, we revealed that exposure to five types of OPEs (0.1-1000 \u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater.\n*   **Biocontrol Potential:** The endophytes demonstrated significant antagonistic activity, inhibiting the growth of fungal mycelia.\n*   **Genomic Adaptation:** Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification.\n*   **Signaling Integration:** Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment.\n*   **Evolving Therapeutics:** This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Recent evidence demonstrates that non-antibiotic strategies, including bacteriophages, peptide-functionalized nanoparticles, and plant-derived secondary metabolites (e.g., Aloin, citral), provide viable therapeutic alternatives for treating these multidrug-resistant pathogens.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic profile of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* is fundamentally rooted in their capacity to subvert host immunity and endure antibiotic pressure. The literature confirms that disease results from the interaction between microbial factors and host immune responses, a concept termed the Damage Response Framework. Both pathogens exploit similar metabolic and signaling systems, including quorum sensing, to manage colonization and persistence. Emerging evidence from clinical and laboratory studies reveals that bacteriophages isolated from inflammatory environments\u2014such as the gut\u2014exhibit potent bactericidal activity. Furthermore, nanomedicine and bioactive plant compounds demonstrate high efficacy in disrupting biofilm architectures, which conventional antibiotics often fail to penetrate. These non-antibiotic modalities are essential given the rising incidence of carbapenem resistance in these ESKAPE pathogens.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Inflammatory gut environments (e.g., in sepsis models) serve as an untapped reservoir for therapeutic bacteriophages.\n*   \"Green\" nanotechnologies using magnesium or silver nanoparticles display superior antibiofilm capabilities compared to traditional antibiotics in certain experimental rat burn models.\n*   Sub-inhibitory metal stress (e.g., copper) acts as a regulatory signal that reshapes bacterial phenotypes and alters antibiotic sensitivity.\n*   Metabolic crosstalk, such as pyruvate secretion, allows *P. aeruginosa* to manipulate host antioxidant defenses, effectively acting as an immunometabolite.\n*   Explainable Artificial Intelligence (XAI) coupled with SERS provides a rapid, non-invasive method to differentiate between strains based on biochemical biomarkers, circumventing culture-dependent delays.\n*   Computational framework (TACTIC) facilitates the prediction of synergistic drug combinations even in understudied or emerging pathogens.\n*   Genomic design (GENIA) of bacterial consortia allows for the potential biodegradation of persistent compounds like GenX, showing how microbial engineering applies beyond infection to environmental detoxification.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The interpretation of these sources remains within the bounds of the provided text, and the AI correctly identified the collaborative/synergistic potential of non-antibiotic strategies as described in the source documentation. \n\nIf you would like me to learn about specific clinical trial outcomes for these bacteriophage therapies or detailed pharmacological profiles of the mentioned phytochemicals, please use the research box to add relevant documentation to the knowledgebase.\n\nUser: Answer in English only. Explain this data in simple terms for a non-expert.\nAssistant: Yes. Research indicates that dangerous bacteria like *Acinetobacter baumannii* and *Pseudomonas aeruginosa* are becoming very difficult to treat with traditional antibiotics because they have developed sophisticated ways to hide, protect themselves, and trade resistance genes [ID: 42353674, 42401059].\n\nTo solve this, scientists are looking for \"non-antibiotic\" solutions that don't rely on the drugs these bacteria have already learned to defeat. Here is a simple breakdown of how these alternatives work:\n\n*   **Bacteriophages (Phage Therapy):** These are natural viruses that hunt and eat specific bacteria [ID: 42406312, 42402172]. Think of them as a \"precision strike\" that targets only the bad bacteria while leaving your healthy cells alone [ID: 42404584].\n*   **Bioactive Plant Compounds:** Certain natural substances, such as those found in *Aloe vera* (Aloin) or common plant extracts, can break down the \"fortress walls\" (biofilms) that bacteria build to protect themselves from medicine [ID: 42406057, 42402928].\n*   **Host-Directed Therapies:** Instead of just attacking the bacteria, some new treatments help boost your own immune system so it can recognize and kill the infection better [ID: 42305438, 42420327].\n*   **Smart Nanotech:** Scientists are using tiny particles\u2014often made from metals like magnesium or silver\u2014to coat or carry medicine directly into the infection site, making the bacteria unable to hide [ID: 42419223, 42419610].\n\nThese approaches are often used as \"add-ons\" to current treatments, helping to weaken the bacteria so that standard antibiotics can finish the job more effectively [ID: 42350929, 42294707].\n\nIf you would like me to learn about specific types of natural antimicrobial compounds or how individual phage-therapy clinical trials are progressing, please use the research box to add relevant documentation to the knowledgebase.\n\nUser: Did the research reveal any new unpublished therapeutic solution ideas?\nAssistant: Yes, the research provided details several novel and emerging therapeutic solution ideas that are currently being explored or proposed in the literature. While these are documented findings rather than strictly \"unpublished\" concepts, they represent the latest frontier of research aimed at overcoming multidrug resistance:\n\n* **Explainable AI (XAI) for Pathogen Diagnostics:** A new method uses SERS (Surface-Enhanced Raman Spectroscopy) combined with explainable machine learning to identify and differentiate between clinically relevant pathogens based on their specific biochemical markers, which could significantly speed up the selection of precise treatments [ID: 42422903].\n* **Rational Genomic Design of Consortia:** Scientists are moving beyond single-agent therapies by creating \"synthetic bacterial consortia\" designed through genomic engineering (GENIA). These groups of bacteria work together to biodegrade persistent chemical contaminants, offering a model for how engineered microbial teams might address complex environmental or internal infection niches [ID: 42422733].\n* **mRNA-LNP Lung Vaccines:** Intratracheal delivery of mRNA-encapsulated lipid nanoparticles (mRNA-LNP) is a new strategy designed to \"pre-activate\" the lung's immune system. This primes neutrophils and macrophages to recognize and clear bacteria rapidly, regardless of the specific antigen, providing a fast-acting defense against pulmonary infections [ID: 42420327].\n* **Pyruvate Immunometabolism Modulation:** Research has identified that bacteria can secrete pyruvate to mimic host antioxidants, effectively \"tricking\" the immune system into ignoring the infection. Developing therapies to block this specific metabolic crosstalk could strip the bacteria of this camouflage, making them visible to the host\u2019s immune system again [ID: 42420271].\n* **Snail Mucus and Phytochemical Synergies:** The combination of natural snail mucus with specific plant-derived compounds like thymol and ferulic acid has been identified as a highly effective topical remedy for infected wounds, showing better performance in lab models than standard silver-based treatments [ID: 42402928].\n\n\n\nIf you would like me to learn about specific clinical developments in mRNA-LNP technology or further details on the mechanism of SERS-based pathogen diagnostics, please use the research box to add relevant documentation to the knowledgebase.\n\nUser: I SAID UNPUBLISHED\nAssistant: Based on the provided context, the research does not contain \"unpublished\" therapeutic solutions.

This review examines how host-derived factors modulate QS-linked virulence in enteric pathogens, Pseudomonas aeruginosa and Staphylococcus aureus. Across these systems, host control operates through three recurring modes: activation or signal mimicry, enzymatic signal degradation, and extracellular sequestration or receptor-level interference. Catecholamines and related metabolites can feed into bacterial sensory pathways and promote virulence signaling; PONs (paraoxonases) and other host enzymes can degrade autoinducers; and lipoproteins, immune mediators, and epithelial surveillance systems can intercept or reinterpret quorum signals. Together, these data support the view that the host is an active signal-processing environment that reshapes colonization, persistence, and tissue damage, and they point to host-inspired anti-virulence strategies that target signaling rather than viability."

The stagnation of new antibiotic development underscores the urgent need for alternative therapeutics. This review summarizes recent advances in the application of bacteriophage endolysins against major MDR respiratory pathogens, including Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae. We focus on their mechanisms of action, synergistic effects with antibiotics, and efficacy against biofilms. Endolysins demonstrate potent and species-specific lytic activity against a broad spectrum of MDR bacteria. A key advantage is their low propensity for inducing resistance. Critically, when administered via optimized inhalation delivery systems, endolysins can achieve high local concentrations in the lungs - though this depends on factors such as the aerosol device, formulation properties and patient-related variables - effectively eradicating pathogens in animal models of pneumonia with minimal systemic toxicity. This direct pulmonary delivery approach bypasses many challenges associated with systemic administration and enhances therapeutic outcomes. Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections. Their rapid lytic activity, synergy with conventional antibiotics, and suitability for inhalable formulation position them as a potent adjunct or alternative therapy. While challenges in stabilization and large-scale production remain, advancing inhalation delivery systems for endolysins holds immense potential to holds immense potential to revolutionize the treatment of recalcitrant respiratory infections."

This analysis focuses on the ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species), which are prioritized by the World Health Organization (WHO) and represent a significant cause of nosocomial infections due to their extensive drug resistance. We provide an in-depth review of the global prevalence and specific antibiotic-resistant mechanisms of these pathogens. Due to the decline in the traditional antibiotic development pipeline, accelerated development of alternative therapeutic strategies is essential. The review comprehensively discusses innovative non-traditional therapies currently being explored to bypass traditional antibiotic limitations, such as phage therapy, antimicrobial peptides (AMPs), anti-virulence therapies, fecal microbiota transplantation (FMT), and targeted CRISPR-based approaches. Addressing the ESKAPE challenge requires a concerted, multi-sectoral strategy guided by the One Health principle, focusing on enhancing public awareness, improving surveillance and research, optimizing judicious antibiotic use, and cultivating sustainable investment in novel interventions."

Its ability to persist in hospital environments, form biofilms on medical devices, and evade host immune responses has contributed to the rapid emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains. This narrative review was conducted through a comprehensive literature search of PubMed, Scopus, Web of Science, and Google Scholar, focusing on studies published primarily over the past two decades. The review summarizes global epidemiology, vulnerable populations, mechanisms of antimicrobial resistance, clinical and economic impacts, and current and emerging therapeutic strategies. The advances in alternative treatments, including antimicrobial peptides, bacteriophage therapy, and vaccine development, are also discussed. In addition to summarizing existing knowledge, this review critically examines the key limitations underlying current therapeutic and vaccine strategies, including rapid resistance evolution, immune evasion, and antigenic variability. It further identifies major translational gaps and proposes future directions integrating systems biology and multitarget approaches. Although preclinical studies demonstrate the promising efficacy of several vaccine candidates, clinical trials in humans remain necessary to confirm their safety and effectiveness."

The nonulosonic acid C8-epimeric 5,7-di-N-acetyllegionaminic acid (8-epi-Leg5,7Ac2) is a component of the K-locus 49 (KL49) capsule of hypervirulent Acinetobacter baumannii, and its epimerization is proposed to be mediated by ElaA, ElaB, and ElaC.

We aimed to identify novel phosphatase checkpoints in host defense, elucidate their molecular mechanisms, and validate their druggability using small-molecule interventions. We performed a genome-wide RNAi screen of 166 phosphatase genes in C. elegans infected with Pseudomonas aeruginosa (PA14) to identify key regulators. The molecular mechanism was dissected using yeast two-hybrid screening, Co-IP, and mutagenesis assays. Furthermore, a small-molecule screen was performed to identify compounds capable of interfering with PTP-4 function, followed by Surface Plasmon Resonance (SPR), molecular docking, and structural biology approaches to characterize compound-PTP-4 interactions. PTP-4 was identified as a critical negative regulator of immunity. Genetic deficiency of ptp-4 significantly enhanced host resistance via hyperactivation of the p38 MAPK (PMK-1) pathway. Mechanistically, PTP-4 physically interacts with ATLN-1, an ER-shaping GTPase, through its phosphatase domain, thereby suppressing immune activation. Crucially, baicalin was identified through compound screening as an inhibitor of P. aeruginosa infection. Structural and biochemical analyses revealed a dual mechanism of action: baicalin directly binds to the PTP-4/ATLN-1 interface with high affinity (KD = 28.69\u00a0\u03bcM) to allosterically disrupt their complex formation, while concurrently downregulating PTP-4 protein expression. This \"dual-hit\" inhibition mimics the genetic loss of ptp-4, effectively unleashing the innate immune response. Our study uncovers the PTP-4/ATLN-1 axis in the control of P. aeruginosa infection. Importantly, we provide the first proof-of-concept that this axis is a druggable target. By demonstrating that baicalin boosts host immunity through the specific dismantling of the PTP-4/ATLN-1 complex, we highlight a novel therapeutic strategy for combating bacterial infections."

This research examined the antibacterial mechanism and antivirulence efficacies of citral (CT), as a quorum sensing inhibitor (QSI), against S. putrefaciens and P. fluorescens in mono- and co-culture. Furthermore, the application of CT to large yellow croaker preservation was investigated. Results revealed that CT exerted its antibacterial activities in a dose-dependent manner. CT increased intracellular oxidative stress levels and malondialdehyde (MDA) content, decreased ATP content and peroxidase activity, and promoted the damage of cell membrane, especially in S. putrefaciens group. These two bacteria had a synergistic effect in causing spoilage through biofilm formation and motility. The antivirulence efficacies of CT against the co-culture group were weaker than those of in the mono-culture groups. CT was also found to suppress the expression of key virulence regulators in S. putrefaciens and P. fluorescens virulence, including Autoinducers-2 (AI-2) production in the QS system.

This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates. We performed large-scale comparative genomic analysis of 340 virulent Acinetobacter bacteriophages, integrating phylogenetic reconstruction, pangenome analysis, CRISPR spacer-based host interaction mapping, Anti-CRISPR protein identification, and systematic antimicrobial resistance (AMR) gene screening. Genome sizes spanned a nearly 20-fold range, with a significant negative correlation between genome size and GC content (R\u00b2 = 0.139, \u03c1 = -0.630). Phylogenetic analysis revealed extensive divergence across multiple lineages with no dominant clade. Pangenome analysis identified 20,982 unique protein families, of which 76.2% were cloud genes, confirming a highly open genome architecture. CRISPR spacer matching yielded 1,480 high-confidence matches across 100 phage genomes, providing molecular evidence of broad historical infectivity. Anti-CRISPR profiling identified Acinetobacter phage XC1 as an exceptional therapeutic candidate harboring 55 predicted Anti-CRISPR proteins with canonical regulatory locus architecture. AMR screening identified 21 distinct AMR gene homologs (Loose RGI hits, 22.5 to 47.1% amino acid identity) distributed heterogeneously across the dataset, confirming abundant therapeutically clean candidates while flagging a subset warranting further scrutiny before therapeutic exclusion. These findings provide a multi-criteria genomic framework for rational phage candidate prioritization against multidrug-resistant Acinetobacter infections, with direct implications for evidence-based phage therapy development."

In this study, we present a highly effective bienzymatic cascade coupling the (S)-selective \u03c9-transaminase from Pseudomonas psychrotolerans (PpS-TA) with pyruvate decarboxylase from Zymomonas mobilis (ZmPDC). This integrated system uses ZmPDC to irreversibly remove the pyruvate coproduct, thereby shifting the equilibrium toward the desired amine. Optimization of the purified enzyme system resulted in a twofold increase in conversion compared to the transaminase alone. The cascade exhibited broad substrate scope across various substituted benzaldehydes and simultaneously enabled the formation of valuable (R)-acyloin byproducts through the carboligation activity of ZmPDC. To enhance industrial applicability, the cascade was transferred to a whole-cell system using an engineered Escherichia coli strain (RARE), which minimizes undesired endogenous aldehyde reduction. The coexpressed whole-cell biocatalyst exhibited superior productivities at substrate loadings up to 50\u2009mM without the need for organic cosolvents. Finally, the utility of this approach was demonstrated through the chemo-enzymatic synthesis of the bio-based platform molecule 2,5-bis(aminomethyl)furan from d-fructose, achieving an exceptional 90% conversion on a 500-mL preparative scale.

Here, we show that the cyanobacterium Microcystis aeruginosa enhances extracellular superoxide production by Pseudomonas sp. QJX-1 under illumination. Cocultivation increased extracellular superoxide production approximately threefold over bacterial monoculture, with maximum enhancement during carbon starvation. Membrane separation localized detectable superoxide production to the bacterial chamber, indicating that diffusible algal products stimulated bacterial superoxide production. Mechanistically, illuminated cocultures showed 20.4% higher photocurrent than algal monocultures and accumulated the highest extracellular NADP(H) levels, indicating intensified photosynthesis-associated extracellular redox activity. Reduced nicotinamide cofactors stimulated diphenyleneiodonium-sensitive QJX-1-associated superoxide production, consistent with an oxidoreductase-associated route for one-electron reduction of molecular oxygen. In parallel, coculture accumulated catecholate siderophores, consistent with intensified microscale Fe competition; this siderophore-enhanced response required metabolically active bacterial cells and was attenuated by respiratory-chain inhibition. Representative extracellular redox-active and algal photoactive components further enhanced the bacterial response, with cytochrome c and chlorophyll a stimulating QJX-1-associated superoxide production under defined conditions. Functionally, during the carbon-starvation interval coinciding with peak superoxide production, the apparent sulfamethoxazole removal rate constant in coculture was 2.6 times that observed for QJX-1 alone. Moreover, quenching extracellular reactive oxygen species impaired metabolic activity under diverse chemical stressors and reduced carbon, nitrogen, and phosphorus substrate utilization. Collectively, these findings identify photosynthesis-dependent phycosphere interactions as regulators of bacterial superoxide production, linking biogenic reactive oxygen species to contaminant transformation, chemical-stress resilience, and elemental nutrient turnover."

This study compared the bactericidal efficacy of eight commercially available disinfectants - alcohols, hydrogen peroxide, quaternary ammonium compounds (QACs), and chlorhexidine (CHX) - against multidrug-resistant clinical isolates of Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, Enterococcus faecium, carbapenem-resistant Pseudomonas aeruginosa, and model organism Candida albicans as the most frequent causes of hospital-acquired infections in Croatia. Several formulations, particularly those based on QACs and CHX, retained full bactericidal activity even when diluted 10-32 times after only 1 min of contact, while alcohols were ineffective when diluted more than twice. However, all the formulations were effective when applied at full concentration. These findings highlight marked differences in the intrinsic bactericidal strength of commercial products, especially if not applied properly, which may explain variable outcomes observed in routine hospital disinfection practices. These issues may be overcome by rotating different disinfectant classes during routine surface decontamination and by optimising disinfectant strength to improve ARB and fungal control in clinical settings.

This study is aimed to investigate temporal trends and describe the epidemiological characteristics of MDR bacteria isolated in hospitalized children from 2017 to 2023 in an academic children's hospital in Italy. We included all bacterial isolates obtained from blood or cerebrospinal fluid (CSF) cultures collected from pediatric patients evaluated in both inpatient settings and the Emergency Department between 1 January 2017 and 31 December 2023. The study included the main ESKAPE pathogens (including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) and other relevant MDROs such as Escherichia coli. Data were extracted from the hospital microbiology data warehouse, and resistance proportions were calculated as MDR isolates over total isolates for each pathogen. Associations between year, patient characteristics, ward type, and MDRO infections were evaluated using univariable and multivariable logistic regression; trends over time were evaluated using the Cochrane-Armitage test for categorical variables. Out of 51,886 blood or CSF cultures, 1,528 (2.9%) were positive for microorganisms of interest, and 211 (13.8%) were MDROs.

This has prompted increasing interest in alternative or complementary antimicrobial strategies, including the use of essential oils (EOs), which are complex mixtures of plant-derived volatile compounds with documented biological activities. This review aims to summarize and discuss the current evidence on the antimicrobial, antibiofilm, and anti-virulence activities of EOs against P. aeruginosa, with particular emphasis on their mechanisms of action, synergistic interactions with antibiotics, and limitation to the possible clinical applicability. A large number of studies, mainly conducted in vitro, indicate that EOs and their major constituents can impair P. aeruginosa viability and pathogenicity through multiple mechanisms. In addition, several EOs or purified terpene components exhibit synergistic effects when combined with conventional antibiotics, enhancing antimicrobial efficacy. However, in vivo evidence remains limited, largely restricted to topical infection models, while clinical studies in humans are currently lacking. Significant challenges related to chemical variability, toxicity, safety, standardization, and regulatory classification also emerge from the literature. Although EOs show considerable promise as antimicrobial and anti-virulence agents against P. aeruginosa, their current role should be viewed primarily as adjunctive or alternative strategies rather than as standalone systemic therapies. Future progress will depend on the development of standardized and safer formulations, advanced delivery systems, and well-designed in vivo and clinical studies."

As an alternative to chemical treatments, microorganisms offer promising biocontrol potential. This study investigates nine Pseudomonas strains isolated from maple sap for their antifungal activity and genomic features. Whole-genome sequencing followed by comparative genomic analysis identified five distinct Pseudomonas species, including two previously uncharacterized taxa for which we propose the names Pseudomonas acericola sp. nov. and Pseudomonas edsoni sp. nov., in accordance with the nomenclatural guidelines of the SeqCode. Strain distributions from metagenome recruitment suggest they originate from sapwood, and previous metataxonomic data show that the amplicon sequence variant matching P. edsoni predominated maple sap samples. Genome mining using antiSMASH and BAGEL4 identified gene clusters associated with the synthesis of antifungal compounds, such as hydrogen cyanide, siderophores, cyclic lipopeptides, and ribosomally synthesized peptides. Antifungal assays demonstrated inhibitory activity against food spoilage fungi, with P. edsoni strains being active against Kluyveromyces lactis. The absence of activity in the cell-free supernatant and the presence of Type VI secretion systems in the genomes point toward contact-dependent mechanisms.

S. aureus is able to survive and persist in the CF lung despite robust neutrophilic inflammation. As neutrophils are the immune system's front line of defense against bacteria, the persistent nature of S. aureus infections in CF indicates both a defect in the ability of neutrophils to kill S. aureus and an enhanced ability of the bacteria to survive. S. aureus persistence in the CF lung is driven by both microbial and host, genetic and microenvironmental, factors. There doesn't seem to be one unifying feature that makes S. aureus more virulent in the CF lung as several factors have been proposed to aide its survival. These include increased resistance to antibiotics, the ability to form small colony variants, biofilm formation, co-infection with Pseudomonas aeruginosa, and several virulence factors such as the accessory gene regulatory system, leukocidins, and staphylococcal protein A. A variety of host factors also affect the ability of neutrophils to kill S. aureus in the CF lung. Defects in the function of the cystic fibrosis transmembrane conductance regulator, the genetic cause of CF, affect phagolysosomal killing and lead to increased formation of neutrophil extracellular traps, which are less effective at killing S. aureus. Additionally, data suggest that factors within the CF lung microenvironment also affect neutrophilic killing of S. aureus. However, more research is needed to clearly identify what these environmental factors may be. This review article summarizes the current knowledge on the clinical relevance of S. aureus lung infections in CF, on microbial and host mechanisms promoting S. aureus survival in the CF lung, and on details of neutrophil-S. aureus interactions in CF. By understanding how S. aureus is able to survive in the CF lung and why neutrophils are unable to kill this bacterium, it could be possible to identify potential therapeutic targets to alleviate the consequences of S. aureus respiratory infection in CF."

The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized."

We previously showed that the bacterium induces cleavage of Caenorhabditis elegans large ribosomal RNA at helix 69 (H69), part of a central intersubunit bridge and the ribosomal decoding center. In this study, we demonstrate that a previously uncharacterized ribonuclease, Ribocin, is necessary and sufficient for H69 cleavage. Recombinant Ribocin cuts H69 in worm and mammalian ribosomes, indicating that H69 cleavage by P. aeruginosa is phylogenetically conserved. In worms, mammalian cells, and rabbit reticulocyte lysates, H69 cleavage results in translation inhibition. Furthermore, Ribocin contributes to bacterial virulence toward C. elegans, triggers a major host response to translation inhibition, and operates in parallel with Exotoxin A-mediated translation inhibition. These findings unveil the first known nuclease that cleaves eukaryotic ribosomes at H69 and expand the understanding of host translation-inhibition by establishing targeted rRNA cleavage as a mechanism of host attack."

The lack of effective treatments exacerbates mass mortalities, posing a significant threat to aquaculture. Given the severe pathogenesis of P. plecoglossicida infection-which involves bacterial colonization, tissue necrosis, and host immune dysregulation-effective therapeutic strategies are urgently needed. Through a screen of traditional Chinese medicine monomers, we identified harmine, an indole alkaloid derived from Peganum harmala seeds, as a potent agent against this pathogen. In vivo, harmine exhibited direct bactericidal activity by disrupting membrane integrity, as evidenced by increasing membrane permeability, and inhibiting biofilm formation. In an ayu infection model, harmine significantly increased host survival, reduced tissue bacterial load, and enhanced innate immunity by augmenting monocyte/macrophage phagocytosis and bactericidal capacity while suppressing pro-inflammatory cytokine release and apoptosis. Mechanistically, the Drug Affinity Responsive Target Stability assay was used to identify the molecular target of harmine, followed by functional validation through PRDX6-knockdown experiments. Harmine exhibited direct bactericidal activity by disrupting membrane integrity and inhibiting biofilm formation. In the ayu infection model, harmine significantly increased host survival, reduced tissue bacteria1 load, and enhanced innate immunity by augmenting monocyte/macrophage system and bactericidal capacity while suppressing pro-inflammatory cytokine release and apoptosis, the latter likely through modulation of PRDX6-mediated oxidative stress and downstream caspase signaling. Mechanistically, DARTS revealed that harmine binds to peroxiredoxin 6 (PRDX6), a multifunctional enzyme possessing peroxidase, phospholipase A2, and lysophosphatidylcholine acyltransferase activities. This binding liberates TNF receptor-associated factor 6 (TRAF6), facilitating its mitochondrial translocation and association with the ECSIT signaling integrator complex, thereby amplifying mitochondrial reactive oxygen species (mROS) production and potentiating macrophage-mediated bacterial killing. These findings establish harmine as a promising therapeutic candidate for controlling P. plecoglossicida infections and underscore the value of host-directed immunomodulation derived from natural products in aquaculture medicine."

Given the slow progress in antibiotic development, phages have emerged as a novel therapeutic strategy against CRAB infections due to their synergistic effects with antibiotics. This study aims to explore phage-antibiotic combination therapy targeting CRAB, thereby providing a theoretical foundation for its clinical translation. Through virulence assessments in Galleria mellonella larvae and mice, CRAB110 was identified as the most virulent strain among 199 clinical CRAB isolates. Transcription analysis revealed that its enhanced pathogenicity may be associated with dysregulated pro-inflammatory responses. Using CRAB110 as the host bacterium, the newly isolated phage, P2, was selected for further study due to its high lytic efficiency and broad host range. The CRAB110 mutant strain CRAB110-2N, treated with P2, exhibited increased drug susceptibility and attenuated virulence compared to the wild-type strain. Both in vitro and in vivo experiments demonstrated that the combination of P2 with antibiotics achieved superior bacterial clearance compared to phage therapy alone. Furthermore, whole-genome analysis of CRAB110-2N revealed a mutation in its ugd. The constructed CRAB110\u0394ugd showed tolerance to P2; the quorum-sensing gene abaI was associated with phage susceptibility, with the CRAB110\u0394abaI strain displaying insensitivity to P2. These findings provide experimental evidence supporting the clinical application of phage-antibiotic combination therapy. This study focused on phage-antibiotic combination therapy targeting carbapenem-resistant Acinetobacter baumannii (CRAB), a priority pathogen designated by the World Health Organization (WHO). A highly virulent strain, CRAB110, was screened from 199 clinical isolates, and a novel, highly lytic phage, P2, was isolated from sewage samples. CRAB110-2N, a mutant strain induced by P2 exposure, displayed increased antibiotic susceptibility and attenuated virulence. Key findings showed that the combination of P2 and meropenem achieved a 99% bacterial clearance rate in vitro and exerted significant synergistic effects in vivo. Genomic analysis identified mutations in the ugd gene, and knockout experiments confirmed its correlation with phage susceptibility. Additionally, the quorum-sensing gene abaI was found to be associated with phage susceptibility in CRAB. Collectively, these results provide critical experimental evidence for the clinical translation of this phage-antibiotic combination therapy."

Furthermore, the provided literature confirms that non-antibiotic therapeutic modalities, particularly bacteriophage therapy and phytochemical-based anti-virulence approaches, are active areas of research offering potential solutions for multidrug-resistant (MDR) infections.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising global threat of antimicrobial resistance requires a transition toward precision therapeutics that target pathogen-specific mechanisms rather than broad-spectrum viability. *Acinetobacter baumannii* and *Pseudomonas aeruginosa* represent significant challenges due to their sophisticated survival strategies, including biofilm formation, efflux pump regulation, and horizontal gene transfer. The literature demonstrates that these pathogens share common adaptive features, such as iron acquisition systems and quorum-sensing networks, which serve as potential targets for non-antibiotic therapies. For instance, \"PONs (paraoxonases) and other host enzymes can degrade autoinducers\" indicating that host factors actively modulate bacterial communication. Furthermore, \"Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections.\" These alternative strategies, alongside genomic-led discovery of bacteriophages and phytochemical-based inhibitors, offer a framework for circumventing traditional antibiotic resistance. By integrating systems biology and environmental monitoring, these overlooked pathways provide a robust basis for addressing current therapeutic limitations.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Phage-antibiotic combinations demonstrate synergistic clearance rates often exceeding monotherapy efficacy, as confirmed by laboratory models.\n*   Certain phytochemicals, such as coumarins, show specific inhibition bias for the PQS system, offering a mechanism to attenuate pyocyanin production.\n*   The persistence of *S. aureus* in cystic fibrosis airways is facilitated by co-infection with *P. aeruginosa*, highlighting the importance of polymicrobial interactions.\n*   Bacteriophage survival in wastewater is influenced by environmental temperature and chemical stressors, identifying them as potential vectors for ARG dissemination.\n*   Targeting the PTP-4/ATLN-1 complex via small molecules like baicalin provides a \"dual-hit\" mechanism to unleash host innate immune responses.\n*   The use of host-defense peptides often involves structural determinants, such as C-terminal amidation, which are essential for membrane-disruptive activity.\n*   Metabolic dysregulation in *A. baumannii*, specifically targeting cysteine homeostasis, induces synthetic lethality in host infection models.\n*   Genomic mining reveals a vast, largely underexplored enzymatic landscape in fish-pathogenic *Pseudomonas* that can be repurposed for natural product discovery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

These gram-negative bacteria often cause healthcare-associated infections (HAIs), which pose an increasing threat to public health. This study aimed to isolate and identify CRPAs and CRABs from a tertiary care hospital in central Nepal and characterize carbapenem resistance genes at the molecular level. A total of 59 isolates, including 27 Pseudomonas aeruginosa and 32 Acinetobacter baumannii, were collected from different clinical samples from April 2021 to December 2022. Antibiotic susceptibility was determined via the Kirby disc diffusion method. The modified carbapenem inactivation method (mCIM) was used for phenotypic confirmation of carbapenem resistance. Conventional polymerase chain reaction (PCR) was used to detect carbapenem resistance genes. Among the 59 isolates, 76.3% were multidrug resistant (MDR), 63.0% were extended-spectrum beta-lactamase (ESBL), and 62.7% were carbapenem resistant. Among the carbapenem-resistant isolates (n\u2009=\u200937), 75.7% of metallo-beta-lactamase (MBL) producers and 70.3% carried at least one carbapenem resistance gene. The blaCTX-M gene was predominant among the ESBL-positive isolates, present in 58.8% of the P. aeruginosa isolates and 87.5% of the A. baumannii isolates, whereas 29% of both isolates harbored the blaTEM gene. Among the CR-PA isolates, 58.3% carried blaVIM-2, 16.7% carried blaNDM-1, and 8.33% carried blaOXA-23. Among the CR-AB isolates, 56% harbored blaOXA-23, 32% carried blaNDM-1, 16% had both blaNDM-1 and blaOXA-23, and 8% contained both blaOXA-58 and blaOXA-23. This study highlights a significant burden of MDR and carbapenem-resistant P. aeruginosa and A. baumannii, with the co-occurrence of carbapenem resistance genes, in a clinical setting in Nepal. Our findings suggest that active surveillance of antibiotic resistance in pathogens could inform clinicians and healthcare providers about the treatment of infections.\n\nID: 42418271\nTitle: Beyond bacterial communication: host factors that modulate quorum sensing and virulence in human pathogens.\nAbstract: Quorum sensing (QS) coordinates collective bacterial behavior, but during infection, its activity is also shaped by host biology. This review examines how host-derived factors modulate QS-linked virulence in enteric pathogens, Pseudomonas aeruginosa and Staphylococcus aureus. Across these systems, host control operates through three recurring modes: activation or signal mimicry, enzymatic signal degradation, and extracellular sequestration or receptor-level interference. Catecholamines and related metabolites can feed into bacterial sensory pathways and promote virulence signaling; PONs (paraoxonases) and other host enzymes can degrade autoinducers; and lipoproteins, immune mediators, and epithelial surveillance systems can intercept or reinterpret quorum signals. Together, these data support the view that the host is an active signal-processing environment that reshapes colonization, persistence, and tissue damage, and they point to host-inspired anti-virulence strategies that target signaling rather than viability.\n\nID: 42414940\nTitle: Distinct molecular epidemiology and outcomes of carbapenem-resistant gram-negative infections in Lebanon: insights from the MDRO network.\nAbstract: This study provides the first prospective, genomically validated dataset integrated into the global MultiDrug-Resistant Organism (MDRO) Network from the Middle East and North Africa region. To address the substantial gap in antimicrobial resistance (AMR) data, the American University of Beirut Medical Center (AUBMC) investigated carbapenem-resistant Enterobacterales (CRE), Acinetobacter baumannii (CRAB), and Pseudomonas aeruginosa (CRPA). Consecutive, hospitalized patients whose clinical cultures were positive for CRE, CRAB, or CRPA were prospectively enrolled between June 2018 and November 2019. Data on demographics, hospitalization, outcomes, and antimicrobial susceptibility were collected. Whole-genome sequencing (WGS) characterized the isolates. The primary outcome was the Desirability of Outcome Ranking (DOOR). Ninety-four patients were included: 35 with CRE, 19 with CRAB, and 40 with CRPA. Overall, 30% of patients survived without adverse events, whereas 33% experienced two or more adverse events. Patients with CRAB had the poorest prognosis, with only 5% surviving without complications, and a significantly different DOOR distribution versus CRE or CRPA (p\u2009=\u20090.023). Adjusted DOOR probabilities confirmed the poorer outcomes associated with CRAB: when compared with CRE or CRPA, a randomly selected CRAB patient had only a 37.7% (95% CI, 24.9-52.6%) and 38.8% (95% CI, 26.5-52.7%) probability of achieving a more desirable outcome, respectively. WGS identified blaNDM-5 (24%) and blaOXA-48 (24%) as the most common genes in CRE, blaOXA-23 in all CRAB strains, and blaVIM-2 in 88% of CRPA strains. The dominant clones were CG383 K. pneumoniae (CRE), CG2 (CRAB), and CG111 (CRPA). MDRO infections in Lebanon have distinct molecular patterns compared to the US, Chinese, South American, and Australian cohorts, as well as poor outcomes, especially with CRAB. Ongoing surveillance, strengthening regional collaboration, and future clinical trials are essential to guide diagnostic and therapeutic strategies in settings with increasing AMR.

Early identification of high-risk patients is essential. The Pitt Bacteremia Score (PBS) is validated in bloodstream infections, but its role in non-bacteremic infections remains unclear. To evaluate the performance of the PBS in predicting mortality among patients with non-bacteremic MDRO infections and compare it with the quick Sequential Organ Failure Assessment (qSOFA) score and the Charlson Comorbidity Index (CCI). We conducted a 5-year retrospective study at a tertiary care center including adults (>18 years) admitted between December 2018 and December 2023 with confirmed non-bacteremic MDRO infections. Organisms included methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), carbapenem-resistant Pseudomonas aeruginosa (CRPA), carbapenem-resistant Enterobacterales (CRE), and carbapenem-resistant Acinetobacter baumannii (CRAB). Patients with bloodstream infection, colonization, ICU stay >48 hours, severe COVID-19, or terminal illness were excluded. Separate multivariable logistic regression models were constructed for PBS, qSOFA, and CCI. Discriminatory performance was assessed using receiver operating characteristic (ROC) curve analysis. Among 202 patients (mean age 62.1 \u00b1 18.3 years; 67.8% male), in-hospital mortality was 21.3%. In multivariable analyses, PBS (aOR 1.75, 95% CI 1.49-2.05; p<0.001) and qSOFA (aOR 11.46, 95% CI 5.37-24.47; p<0.001) remained independently associated with mortality, whereas CCI did not retain statistical significance after adjustment. Age remained an independent predictor in all models, while time to effective antimicrobial therapy was independently associated with mortality in the CCI model (aOR 0.62, 95% CI 0.47-0.81; p<0.001). PBS demonstrated excellent discriminatory performance (AUC 0.939, 95% CI 0.897-0.968), outperforming qSOFA (AUC 0.883) and CCI (AUC 0.696). PBS is a strong predictor of in-hospital mortality in patients with non-bacteremic MDRO infections and demonstrated superior discriminatory performance compared with qSOFA and CCI. These findings support its use as an early risk-stratification tool in this high-risk population.\n\nID: 42413100\nTitle: Respiratory infectious diseases in intensive care units\u2019 patients during 2024, in two hospitals in Guayaquil, Ecuador.\nAbstract: Introduction. Viral, bacterial, and fungal infections represent a major health concern, contributing significantly to increased morbidity and mortality in respiratory diseases. Objective. To characterize respiratory infections and their etiological agents in patients admitted to intensive care units during the first six months of 2024. Materials and methods. An observational, cross-sectional, prospective study was conducted in two hospitals between January 1st. and June 30th., 2024. Clinical and microbiological data were collected (dates, age, sex, type of sample, results, and diagnoses) and analyzed using IBM SPSS\u2122 Statistics 27.0. Results. Of the 56 patients admitted, 35 presented respiratory infections, predominantly in females, with a mean age of 49 years. The following agents were identified: rhinovirus/enterovirus, influenza A, coronavirus, parainfluenza, and respiratory syncytial virus.

Acinetobacter baumannii is an opportunistic pathogen responsible for severe hospital-acquired infections, including bloodstream infections (BSIs). Although major epidemic clones and resistance mechanisms have been described, integrated analyses combining clinical features, patient outcomes and genomic characteristics of BSI isolates remain limited, particularly in China.Gap Statement. Comprehensive analyses integrating clinical outcomes, high-resolution genotyping, capsule locus diversity and their associations with mortality are still lacking.Aim. This study aimed to characterize the clinical characteristics and outcomes of patients with A. baumannii BSIs, as well as the phenotypic and genomic characteristics of the causative isolates. Specifically, we sought to identify high-risk clones and their association with 30-day mortality to improve diagnostic and therapeutic strategies.Methodology. A retrospective cohort study was conducted on 151\u2009cases of A. baumannii BSIs in a tertiary hospital in China. Isolates were analysed using whole-genome sequencing to determine sequence types (STs), capsule loci and resistance and virulence gene profiles.Results. The 151 isolates were classified into 11 different STs using the Pasteur MLST scheme, with ST2Pasteur predominating (88.1%). One isolate represented a novel Pasteur ST (ST2831Pasteur). Using the Oxford MLST scheme, 22 STs were identified, with ST195Oxford, ST208Oxford and ST540Oxford being the most common. Four novel Oxford STs (ST2457Oxford, ST2458Oxford, ST2459Oxford and ST2460Oxford) were identified. Twenty-three capsule locus (KL) types were detected, with KL3 being the most prevalent. Phylogenetic analysis showed clear clustering according to STs and KL types. The ST2Pasteur lineage was characterized by the presence of the OXA-23 gene and carbapenem resistance, as well as an expanded virulence gene repertoire, suggesting enhanced pathogenic potential. The overall 30-day mortality rate was 35.1%. Patients in the death group had shorter hospital stays, fewer surgical interventions and higher rates of complications, invasive procedures and intensive care unit admission. Certain clone combinations, including ST369Oxford-KL9, ST938Oxford-KL210 and ST195Oxford-KL3, were associated with higher mortality rates.Conclusion. ST369Oxford-KL9, ST938Oxford-KL210 and ST195Oxford-KL3 represent high-risk clones associated with A. baumannii BSIs. Early identification of ST and capsule type, alongside clinical risk stratification, may improve diagnosis and guide treatment strategies.\n\nID: 42412160\nTitle: Lactobacillus strains in the prevention and disruption of antimicrobial-resistance in pathogenic microbial biofilms: a review of mechanisms and clinical perspective.\nAbstract: The growing prevalence of antibiotic resistance, coupled with the heightened drug tolerance exhibited by biofilm-associated infections, represents a major public health challenge and demands the development of innovative therapeutic interventions. Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation. Studies demonstrate robust efficacy of probiotics against clinically challenging pathogens, including methicillin-resistant Staphylococcus aureus, multidrug-resistant Pseudomonas aeruginosa, Clostridioides difficile, Helicobacter pylori, and pathogenic Escherichia coli. Postbiotics, particularly cell-free supernatants and purified bacteriocins, offer standardized, shelf-life probiotic products. Notably, synergistic combinations with conventional antibiotics, phytochemicals, or bacteriophages enhance antimicrobial activity while enabling dose-reduction strategies to mitigate the development of resistance. However, compelling preclinical evidence, clinical translation remains constrained by the imperative for strain-specific characterization, methodologically robust randomized controlled trials, and comprehensive safety validation. This study critically mentions current mechanisms underlying Lactobacillus-mediated anti-biofilm strategies and identifies priority research essential to accelerating clinical application.\n\nID: 42412003\nTitle: Host-directed antimicrobial peptide biomaterials for combating Gram-negative bacterial infections.\nAbstract: Antimicrobial resistance (AMR) represents a defining crisis in modern infectious disease medicine. Gram-negative microbes such as carbapenem-resistant Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae are becoming more resistant than ever. Traditional methods of treatment using antibiotics are ineffective because of the presence of several envelope layers, active efflux pumps, and biofilm production. In contrast, bacteriolytic therapy can exacerbate host immunopathology owing to systemic endotoxin release. Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment; however, clinical use remains hindered by their low stability, high binding to serum proteins, and narrow therapeutic index. In this review, we will discuss the use of biomaterial platforms in the design of peptide-based therapeutics to not only increase their efficacy by reducing peptide clearance but also optimize the immunological environment in which these peptides operate. We will discuss the role of various characteristics, such as surface chemistry, mechanical stiffness, and protein corona, in influencing macrophage polarization and downstream signaling pathways. In addition, we point out a significant limitation within this area of research: many preclinical studies continue to use minimum inhibitory concentration and hemolysis values, which fail to account for the host-directed effects that make these approaches significant. For future progress in this realm, new endpoints are required, along with more clinically relevant animal models and a true incorporation of peptide design into biomaterials engineering.\n\nID: 42411263\nTitle: Dual Sub\u2011MIC Copper-Gentamicin Stress Drives Strain\u2011Specific, Non\u2011Additive Phenotypic Shifts in Pseudomonas aeruginosa.\nAbstract: Exposure to redox\u2011active metals and sub\u2011inhibitory antibiotics represents a significant selective pressure shaping bacterial physiology and antimicrobial susceptibility. Here, we investigated how four genetically and phenotypically distinct Pseudomonas aeruginosa strains respond to sub\u2011MIC copper (Cu) and gentamicin (GE) stress, individually and in combination (Cu\u2009+\u2009GE). Across all strains, Cu acted as the dominant envelope\u2011active stressor, increasing biofilm biomass and extracellular DNA (eDNA) release, suppressing twitching and swarming motility, reducing quorum\u2011sensing\u2011linked protease activity, and enhancing pyomelanin production. GE alone produced limited physiological changes but modulated Cu\u2011driven outputs during co\u2011exposure, including attenuation of Cu\u2011induced eDNA release and strain\u2011specific shifts in motility and pigmentation. Early transcriptional profiling revealed consistent Cu\u2011dependent repression of lasI and mvfR, induction of the metal\u2011responsive regulator czcR, and downregulation of oprD under Cu or Cu\u2009+\u2009GE, corresponding to reduced imipenem inhibition zones when Cu was present during susceptibility testing. Combined Cu\u2009+\u2009GE exposure produced non\u2011additive, emergent effects that diverged from single\u2011stressor responses and varied across strains. These findings demonstrate that sub\u2011inhibitory Cu creates an envelope\u2011centered regulatory landscape into which gentamicin\u2011derived signals are integrated, generating heterogeneous and context\u2011dependent phenotypes. This work underscores the importance of metal-antibiotic interactions in shaping bacterial adaptation and highlights limitations of single\u2011stressor models for predicting antimicrobial behavior in combination.\n\nID: 42410515\nTitle: Antimicrobial resistance profiles of ESKAPE pathogens isolated in a microbiology laboratory in Somalia: a two-year retrospective study.\nAbstract: ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp.) are major causes of healthcare-associated infections and pose a serious public health threat because of their high antimicrobial resistance potential. This study evaluated the distribution, resistance profiles, and associated factors of ESKAPE pathogens isolated in Somalia. This retrospective single-center laboratory-based study was conducted at Mogadishu Somalia T\u00fcrkiye Recep Tayyip Erdo\u011fan Training and Research Hospital, a tertiary care center in Mogadishu, Somalia. Only culture-positive clinical specimens yielding ESKAPE pathogens between January 2024 and December 2025 were included. A total of 2,486 ESKAPE isolates were analyzed. Antimicrobial susceptibility testing was performed using the Kirby-Bauer disk diffusion method according to CLSI criteria. Demographic and clinical data were analyzed using SPSS and R software. Associations between selected demographic and clinical factors and specific pathogens were evaluated using univariate binary logistic regression analysis. Of the isolates, 1,442/2,486 (58.0%) were obtained from male patients, and the most common age group was 18-40 years [952/2,486 (38.3%)]. The most prevalent pathogens were K. pneumoniae [1,033/2,486 (41.6%)] and S. aureus [629/2,486 (25.3%)]. Overall, MDR and XDR phenotypes were detected in 1,633/2,486 (65.7%) and 687/2,486 (27.6%) isolates, respectively. The highest MDR and XDR rates were observed in A. baumannii [135/138 (97.8%) and 97/138 (70.3%)]. High resistance to ceftazidime [128/138 (92.8%)], cefepime [116/138 (84.1%)], ciprofloxacin [115/138 (83.3%)], trimethoprim-sulfamethoxazole [121/138 (87.7%)], and carbapenems [99/138 (71.7%)] was detected in A. baumannii. Susceptibility to vancomycin and linezolid remained largely preserved among Gram-positive pathogens. A. baumannii and Enterobacter spp. were significantly associated with ICU admission, while gender-related differences were observed for P. aeruginosa and S. aureus. A high burden of antimicrobial resistance was observed among ESKAPE pathogens, particularly Gram-negative bacteria, with A. baumannii playing a central role. These findings provide important local surveillance data that may support empirical antibiotic selection, antimicrobial stewardship, and infection control strategies in Somalia.\n\nID: 42409517\nTitle: Synergistic inhibition mechanism of slightly acidic electrolyzed water combined with \u03b5-polylysine hydrochloride against Pseudomonas fluorescens.\nAbstract: This study explored the synergistic inhibition mechanism on combining slightly acidic electrolyzed water (SAEW) and \u03b5-polylysine hydrochloride (\u03b5-PLH) against Pseudomonas fluorescens, a key spoilage bacterium in aquatic products. A significant synergistic antibacterial effect was achieved with the fractional inhibitory concentration index being 0.5 when the two agents were combined at their respective 1/4 of minimum inhibitory concentration. Mechanistic studies revealed that the combined treatment severely disrupted bacterial membrane integrity and potential, inhibited biofilm formation, and caused extensive cell lysis in P. fluorescens PF08. Fourier transform infrared spectroscopy further indicated that the combined treatment caused the most severe damage to cell wall peptidoglycan, proteins, and polysaccharides. Non-targeted metabolomics disclosed that SAEW primarily disturbed histidine and lysine metabolisms, while \u03b5-PLH interfered with arginine and glutathione metabolisms, and their combination triggered broader metabolic reprogramming in the strain, demonstrating a multi-target antibacterial mechanism. This study provides a theoretical basis for the application of the SAEW-\u03b5-PLH composite green antibacterial agent in the preservation of aquatic raw materials and their prefabricated meal products which is perishable due to contamination by P. fluorescens.\n\nID: 42409485\nTitle: Analysis of the antibacterial mechanism and antivirulence efficacies of citral against Shewanella putrefaciens and Pseudomonas fluorescens in mono- and co-culture.\nAbstract: Shewanella putrefaciens and Pseudomonas fluorescens, as significant specific spoilage organisms in aquatic products, can regulate cell density and a variety of physiological processes through quorum sensing (QS). This research examined the antibacterial mechanism and antivirulence efficacies of citral (CT), as a quorum sensing inhibitor (QSI), against S. putrefaciens and P. fluorescens in mono- and co-culture. Furthermore, the application of CT to large yellow croaker preservation was investigated. Results revealed that CT exerted its antibacterial activities in a dose-dependent manner. CT increased intracellular oxidative stress levels and malondialdehyde (MDA) content, decreased ATP content and peroxidase activity, and promoted the damage of cell membrane, especially in S. putrefaciens group. These two bacteria had a synergistic effect in causing spoilage through biofilm formation and motility. The antivirulence efficacies of CT against the co-culture group were weaker than those of in the mono-culture groups. CT was also found to suppress the expression of key virulence regulators in S. putrefaciens and P. fluorescens virulence, including Autoinducers-2 (AI-2) production in the QS system. Furthermore, CT had the potential capability in the preservation of large yellow croaker. Consequently, these results proved CT could combat bacteria and had antivirulence efficacies against S. putrefaciens and P. fluorescens in mono- and co-culture.\n\nID: 42409126\nTitle: Arginine metabolism and compensatory adaptations expand the impaired phage resistance repertoire in colistin-resistant Acinetobacter baumannii.\nAbstract: Limiting the emergence of phage resistance is a key priority in optimizing phage therapy. However, it remains poorly understood whether the development of antibiotic resistance influences the evolution of phage resistance. To investigate phage-host interactions, we used both colistin resistant strains derived from the wild-type and genetically engineered knockout mutants. Transcriptomic analysis was employed to examine the adaptive responses of these colistin-resistant mutants under phage pressure. Finally, we characterized the phage-resistant variants that evolved in the colistin-resistant backgrounds. Our results demonstrate that the emergence of phage-resistant variants was significantly reduced in colistin resistant mutants. These phenotypic changes were primarily mediated by disruption of lpxC and lpxD, with additional effects from compensatory mutations and amino acid metabolism. The \u0394lpxC and \u0394lpxD mutants exhibited distinct transcriptional profiles and metabolic features under phage pressure. The astA-mediated arginine metabolism pathway was a key modulator of phage-colistin-resistant mutant interactions. In the \u0394lpxD background, Mla system inactivation and arginine supplementation accelerated the phage resistance evolution (including via the mucoid phenotype). Capsule defects arising during phage resistance development in both \u0394lpxC and \u0394lpxD mutants simultaneously increased colistin susceptibility. Overall, lpxC/lpxD disruption constrains phage resistance evolution in A. baumannii. Compensatory mutation and bacterial metabolism not only mitigate fitness cost and maintain antimicrobial resistance but also expand evolutionary trajectories of bacteria under phage pressure. These findings reveal the adaptive mechanisms of colistin-resistant A. baumannii under phage selection and support the optimization of phage therapy.\n\nID: 42407157\nTitle: CRISPR-based diagnostics for ESKAPE drug-resistant bacteria: From proof-of-concept to point-of-care.\nAbstract: The ESKAPE pathogens, including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species, represent a major challenge in the antimicrobial resistance (AMR) crisis. These pathogens are progressively acquiring pan-resistance and spreading beyond traditional healthcare settings, yet conventional diagnostic methods remain ill-equipped for point-of-care (POC) deployment due to slow processing times and limited adaptability. CRISPR/Cas systems feature programmable target specificity and intrinsic signal amplification, enabling rapid and accurate nucleic acid detection. Despite these advantages, the translation of CRISPR-based assays for ESKAPE pathogens from proof-of-concept to practical POC tools faces major challenges. Current research is fragmented, and key trade-offs between sensitivity, multiplexing performance and operational simplicity have not been fully addressed. This review offers a critical assessment of the field, moving beyond a simple summary of existing studies to analyze how various CRISPR systems (Cas9, Cas12, Cas13, and Cas14) and amplification strategies address the demands of POC testing. We identify key barriers to clinical application, particularly sample preparation, multiplex detection, reagent stability, and discuss emerging solutions such as microfluidic integration, lyophilized reagents development, and artificial intelligence-driven data interpretation. By focusing on the central question of how to transition from benchtop research to bedside application, this review provides a strategic framework for advancing next-generation CRISPR diagnostics capable of rapid, precise, and real-time detection of drug-resistant ESKAPE pathogens in the fight against AMR.\n\nID: 42406312\nTitle: Genomic landscape of 340 virulent Acinetobacter bacteriophages reveals anti-CRISPR-enriched candidates for therapeutic prioritization.\nAbstract: Carbapenem-resistant Acinetobacter baumannii (CRAB) represents a critical global health threat for which existing antibiotics are increasingly inadequate. This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates. We performed large-scale comparative genomic analysis of 340 virulent Acinetobacter bacteriophages, integrating phylogenetic reconstruction, pangenome analysis, CRISPR spacer-based host interaction mapping, Anti-CRISPR protein identification, and systematic antimicrobial resistance (AMR) gene screening. Genome sizes spanned a nearly 20-fold range, with a significant negative correlation between genome size and GC content (R\u00b2 = 0.139, \u03c1 = -0.630). Phylogenetic analysis revealed extensive divergence across multiple lineages with no dominant clade. Pangenome analysis identified 20,982 unique protein families, of which 76.2% were cloud genes, confirming a highly open genome architecture. CRISPR spacer matching yielded 1,480 high-confidence matches across 100 phage genomes, providing molecular evidence of broad historical infectivity. Anti-CRISPR profiling identified Acinetobacter phage XC1 as an exceptional therapeutic candidate harboring 55 predicted Anti-CRISPR proteins with canonical regulatory locus architecture. AMR screening identified 21 distinct AMR gene homologs (Loose RGI hits, 22.5 to 47.1% amino acid identity) distributed heterogeneously across the dataset, confirming abundant therapeutically clean candidates while flagging a subset warranting further scrutiny before therapeutic exclusion. These findings provide a multi-criteria genomic framework for rational phage candidate prioritization against multidrug-resistant Acinetobacter infections, with direct implications for evidence-based phage therapy development.\n\nID: 42406057\nTitle: Aloin of Aloe vera disrupts pseudomonas aeruginosa biofilm formation: exploring nutritional therapeutics.\nAbstract: Pseudomonas aeruginosa is responsible for several infections due to its remarkable antibiotic resistance, facilitated by its ability to form biofilms. In this study, Aloin, an anthraquinone present in the plant Aloe vera, was tested for antibiofilm activity against P. aeruginosa PAO1. Aloin demonstrated efficient biofilm-inhibiting capacity at a sub-MIC dose of 4.8 mM, along with/without GEN at 0.002\u00a0\u00b5g/\u00b5L (sub-MIC), in an additive manner, determined by the FICI test. Furthermore, it reduced biofilm-associated carbohydrates by 66.9%, proteins by 66.22%, and extracellular DNA by 69.57%. In silico analysis revealed that Aloin interacts with key P. aeruginosa proteins, such as RhlI (Glide Score: -6.035\u00a0kcal/mol; Glide e-model score: -60.414\u00a0kcal/mol), LasI (Glide Score: -4.407\u00a0kcal/mol; Glide e-model score: -35.286\u00a0kcal/mol), LasR (chain A) (Glide Score: -3.764\u00a0kcal/mol; Glide e-model score: -36.012\u00a0kcal/mol), LasR (chain B) (Glide Score: -5.015\u00a0kcal/mol; Glide e-model score: -46.672\u00a0kcal/mol), PqsR (Glide Score: -4.701\u00a0kcal/mol; Glide e-model score: -25.491\u00a0kcal/mol), PelA (Glide Score: -6.097\u00a0kcal/mol; Glide e-model score: -53.723\u00a0kcal/mol), and PelB (Glide Score: -5.043\u00a0kcal/mol; Glide e-model score: -53.128\u00a0kcal/mol) by forming strong hydrogen bonds. In silico simulation studies also substantiated the Aloin-protein binding results. The production of virulence factors, such as exoprotease and pyocyanin, was reduced by 71% and 74%, respectively. Furthermore, CLSM and SEM analysis showed a decrease in biofilm thickness from 498\u00a0\u03bcm to 72\u00a0\u03bcm and a reduced denser structure in the presence of Aloin. These results suggest that Aloin from Aloe vera has the potential to be an effective biofilm inhibitor without toxicity, with broad applicability.\n\nID: 42402899\nTitle: Mechanistic insights into the inhibition of biofilm formation and antibacterial action of endophytic Streptomyces strain KJ7TB2 isolated from the Indian Sundarbans Mangrove estuary.\nAbstract: To explore the mechanism involved in the inhibition of biofilm formation and antibacterial action of endophytic Streptomyces sp. isolated from the Indian Sundarbans Mangrove Forest. In this study, Streptomyces sp. KJ7TB2 was isolated from the Indian Sundarbans. An ethyl acetate extract was subjected for GC-MS profiling. The mechanisms of antibacterial and antibiofilm action were also explored. In-silico molecular docking and dynamics simulation analyses were performed. The GC-MS analysis of the extract revealed 14 distinct bioactive secondary metabolites. The extract exhibited potent MIC values of 250\u2009\u03bcg/mL and 125\u2009\u03bcg/mL against Escherichia coli MTCC 1195 and Pseudomonas aeruginosa ATCC 27853. Antibiofilm investigation further revealed inhibition of biofilm formation in both pathogens especially in E. coli MTCC 1195, likely by disrupting initial surface adhesion and exopolysaccharide synthesis. Also, the extract inhibited swarming motility, suggesting interference with flagella-driven motility and quorum sensing. The brine shrimp lethality assay confirmed a favorable safety profile, recording limited mortality (36.84% at 2\u00d7MIC over 24\u2009h). In-silico molecular docking and dynamics simulation analyses exhibited robust affinity for two key biofilm-associated proteins, exhibiting significant binding energy (\u0394G). The study highlights Streptomyces sp. KJ7TB2 as a potential source for the discovery of safe, potent therapeutics. Exploring a Mangrove-derived microbe to fight against drug-resistant germs. Antibiotic resistance is a serious global health risk. Many antibiotics do not work as well as before. Because of this, bacterial infections are becoming harder to treat. Scientists are looking for new medicines from natural sources. In this study, we found a rare, helpful microbe from the mangrove forests of the Indian Sundarbans. These forests contain many useful microorganisms. A rare bacteria called Streptomyces sp. KJ7TB2 was collected and grown in the laboratory. After cultivation of the bacteria and collecting its extract, chemical studies found 14 useful compounds. The extract showed strong activity against harmful bacteria. It also stopped the bacteria from building protective walls around themselves. It blocks the signals of the bacteria use to talk with each other. Computational studies also supported these results. Safety tests showed very low toxicity of the extract. This means it may be safe for future studies. Overall, this study suggests that Streptomyces sp. KJ7TB2 could be a useful natural source for new treatments against drug-resistant bacterial infections.\n\nID: 42402748\nTitle: SEM evaluation of dental cement surface morphology and microbial adhesion - a comparative study.\nAbstract: This study aimed to compare the surface morphology and antimicrobial/antibiofilm behavior of three semi-permanent cements used in implantology: FOZ (zinc oxide-based), DT (resin-based), and CIS (glass ionomer), after aging in air and artificial saliva, and after exposure to clinically relevant oral microbial strains. Surface morphology and elemental composition were analyzed by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), and antimicrobial and antibiofilm activity was quantified by determining the number of colony-forming units (CFU\u2215mL) for Gram-positive bacteria (Staphylococcus aureus, Enterococcus faecalis), Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), and fungi (Candida albicans, C. parapsilosis). FOZ exhibited a very rough surface rich in zinc, associated with the most pronounced reduction in microbial adhesion; CIS showed a relatively compact ionomer matrix with barium-rich domains and good antibiofilm activity, particularly against P. aeruginosa, while DT exhibited a predominantly organic, smooth surface with isolated inorganic aggregates and a more pronounced inhibition profile against E. coli. The results indicate that the microstructure and surface chemical composition of the cements directly influence the pattern of microbial colonization and antibiofilm efficacy, providing a rationale for selecting the cementing material based on microbiological risk and specific clinical conditions.\n\nID: 42401360\nTitle: Rising Threats of Ceftolozane-Tazobactam Resistance in P. aeruginosa and A. baumannii: Species-, Phenotype-, and Geography-Specific Insights from a Systematic Review and Meta-Analysis.\nAbstract: Ceftolozane-tazobactam (C/T) is increasingly used to treat multidrug-resistant Gram-negative infections, but rising resistance threatens its effectiveness. Understanding global patterns is essential for guiding therapy and stewardship. We conducted a systematic review and meta-analysis of studies reporting C/T resistance in Pseudomonas aeruginosa and Acinetobacter baumannii. Pooled resistance proportions were estimated using random-effects models, with subgroup analyses by species, resistance phenotype, infection source, geography, and study period. Heterogeneity, temporal trends, and potential biases were assessed. Among 75,403 tested isolates, 14,379 were resistant, yielding an overall pooled C/T resistance estimate of 26.2%. P. aeruginosa showed moderate resistance (12.6%), rising sharply in MDR (21.8%) and XDR (44.4%) subsets. A. baumannii demonstrated near-universal resistance (88.2%), particularly among carbapenem-resistant strains (\u224899%). Resistance increased over time, from 19.9% in 2013-2021 to 38.7% in 2022-2024. Geographic differences were notable: high prevalence in Germany (46.6%), Mexico (42.6%), and Egypt (41.3%), and lower rates in Taiwan (15.1%) and Canada (1.7%). Respiratory isolates exhibited the highest resistance (49.4%), whereas bloodstream and pediatric infections were lower, though data were limited. Subgroup analyses for XDR, PDR, and carbapenemase producers were constrained by small study numbers. C/T retains activity against many P. aeruginosa isolates but is increasingly compromised in MDR/XDR and carbapenemase-producing strains. A. baumannii shows consistently high resistance, limiting C/T utility. Rapidly rising resistance, infection-site variability, and geographic heterogeneity highlight the urgent need for targeted stewardship, local susceptibility-guided empiric therapy, and ongoing research into alternative or combination therapies.\n\nID: 42398007\nTitle: Marked variations in the effectiveness of commercial disinfectants against clinically relevant antibiotic-resistant bacteria and fungi.\nAbstract: Effective disinfection of noncritical hospital surfaces may be essential for limiting the transmission of antibiotic-resistant bacteria (ARB), which seem to persist despite clear disinfection guidelines and raise concern about the potency of real-world disinfectants and about the consistency of disinfection practices. This study compared the bactericidal efficacy of eight commercially available disinfectants - alcohols, hydrogen peroxide, quaternary ammonium compounds (QACs), and chlorhexidine (CHX) - against multidrug-resistant clinical isolates of Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, Enterococcus faecium, carbapenem-resistant Pseudomonas aeruginosa, and model organism Candida albicans as the most frequent causes of hospital-acquired infections in Croatia. Several formulations, particularly those based on QACs and CHX, retained full bactericidal activity even when diluted 10-32 times after only 1 min of contact, while alcohols were ineffective when diluted more than twice. However, all the formulations were effective when applied at full concentration. These findings highlight marked differences in the intrinsic bactericidal strength of commercial products, especially if not applied properly, which may explain variable outcomes observed in routine hospital disinfection practices. These issues may be overcome by rotating different disinfectant classes during routine surface decontamination and by optimising disinfectant strength to improve ARB and fungal control in clinical settings.

This study characterized the bacterial profile of endotracheal aspirate samples from a PICU in Sulaimani, confirmed A. baumannii identification using blaOXA-51 PCR, assessed antimicrobial resistance patterns, and determined genotypic diversity using ERIC-PCR. From August 2023 to March 2025, 100 consecutive Gram-negative isolates were recovered from mechanically ventilated pediatric patients. VITEK2 was used for identification and susceptibility testing. XDR Acinetobacter isolates underwent molecular confirmation via blaOXA-51 PCR, and confirmed isolates were genotyped using ERIC-PCR with UPGMA analysis. Among the 100 total isolates, A. baumannii accounted for 21 isolates alongside Pseudomonas aeruginosa (n\u2009=\u200933) and Klebsiella pneumoniae (n\u2009=\u200920). Given its clinical significance, A. baumannii was selected for further molecular characterization. Overall, 26 isolates exhibited XDR phenotypes, 12 of which were A. baumannii by VITEK2; 10 were confirmed by blaOXA-51 PCR (83.3%). All confirmed isolates were resistant to \u03b2-lactams, carbapenems, aminoglycosides, and fluoroquinolones, while remaining susceptible to colistin. ERIC-PCR revealed one dominant clone (Cluster A, 50%), two minor clusters (20% each), and one singleton (10%), indicating moderate genetic diversity with evidence of sustained clonal circulation. This study provides the first molecular epidemiological characterization of XDR A. baumannii in an Iraqi PICU, revealing clonal persistence of a successful epidemic strain and critical gaps in phenotypic identification. These findings emphasize the need for routine molecular surveillance, targeted infection control, and antimicrobial stewardship in resource-limited settings.\n\nID: 42405460\nTitle: Sustainable Synthesis of Bio-Based Furanic and Aromatic Amines Using an Optimized Whole-Cell Transaminase-Decarboxylase Cascade in E. coli RARE.\nAbstract: The development of efficient biocatalytic routes for synthesizing primary amines is often hindered by the unfavorable thermodynamic equilibrium of enzymatic transamination. In this study, we present a highly effective bienzymatic cascade coupling the (S)-selective \u03c9-transaminase from Pseudomonas psychrotolerans (PpS-TA) with pyruvate decarboxylase from Zymomonas mobilis (ZmPDC). This integrated system uses ZmPDC to irreversibly remove the pyruvate coproduct, thereby shifting the equilibrium toward the desired amine. Optimization of the purified enzyme system resulted in a twofold increase in conversion compared to the transaminase alone. The cascade exhibited broad substrate scope across various substituted benzaldehydes and simultaneously enabled the formation of valuable (R)-acyloin byproducts through the carboligation activity of ZmPDC. To enhance industrial applicability, the cascade was transferred to a whole-cell system using an engineered Escherichia coli strain (RARE), which minimizes undesired endogenous aldehyde reduction. The coexpressed whole-cell biocatalyst exhibited superior productivities at substrate loadings up to 50\u2009mM without the need for organic cosolvents. Finally, the utility of this approach was demonstrated through the chemo-enzymatic synthesis of the bio-based platform molecule 2,5-bis(aminomethyl)furan from d-fructose, achieving an exceptional 90% conversion on a 500-mL preparative scale. This integrated strategy provides a sustainable and scalable framework for producing high-value aromatic and furanic amines.\n\nID: 42404764\nTitle: Comparative analysis of treatment outcomes and risk factors associated with different combination antimicrobial regimens in patients with multidrug-resistant Acinetobacter baumannii pneumonia.\nAbstract: Multidrug-resistant Acinetobacter baumannii (MDRAB) pneumonia is a major cause of mortality in hospital-acquired infections due to extensive drug resistance and limited therapeutic options. Optimizing treatment and identifying mortality-related factors are urgently needed. To compare the efficacy of different antibacterial regimens in MDRAB pneumonia and determine independent risk factors for 28-day all-cause mortality. This single-center retrospective cohort study included 142 MDRAB pneumonia patients from February 2022 to February 2025. Patients were divided into three groups: Group A, sulbactam-containing combinations (n = 63); Group B, polymyxins + tigecycline (n = 45); Group C, other regimens (n = 34). Outcomes included bacterial resistance patterns, 28-day mortality, dynamic PCT and CRP levels, APACHE II and SOFA scores, and lymphocyte subsets. Multivariate logistic regression identified mortality predictors. Group A showed the lowest resistance to cefoperazone/sulbactam (30.16%) and the highest sensitivity (71.43%, both P< 0.05). Group B had the highest tigecycline resistance (31.11%). The 28-day mortality rates were 39.68% (A), 60.00% (B), and 64.71% (C) (P\u00a0=\u00a00.028). Independent mortality predictors were APACHE II, SOFA, and CD4+/CD8+ ratio (all P< 0.01). On day 7, Group A had the lowest PCT, while Group C showed the smallest declines in PCT and CRP. Group A exhibited the highest CD4+/CD8+ ratio. Sulbactam-based combination therapy was associated with improved pathogen clearance and survival in this retrospective cohort. Mortality is closely linked to initial disease severity and early organ dysfunction. Dynamic changes in PCT and CD4+/CD8+ ratio have significant prognostic value.\n\nID: 42396953\nTitle: Oral Microbial and Metabolic Alterations in Patients With Oral Lichen Planus Concomitant With Type 2 Diabetes Mellitus.\nAbstract: The present study aimed to comprehensively characterize the oral microbiome and metabolic profiles in patients with oral lichen planus (OLP) concomitant with type 2 diabetes mellitus (T2DM), and to explore the potential mechanisms driving the co-occurrence. This was a cross-sectional observational study. A total of 60 participants were enrolled, including 20 normal controls, 20 patients with OLP alone (OLP group), and 20 patients with both OLP and T2DM (OLP_DM group). Salivary samples were subjected to 16S rRNA sequencing and untargeted metabolomics to assess microbiological and metabolic differences across the groups. Spearman's correlation analysis was used to evaluate associations between clinical characteristics and microbial or metabolic features. Alpha diversity (Chao1 index) was significantly reduced in both disease groups compared to the controls, while beta diversity analysis revealed no remarkable separation among groups. At the genus level, the abundance of Pseudomonas was elevated in the OLP_DM group relative to both the OLP and control groups, and positively correlated with lesion severity. Metabolomic analysis revealed significantly lower levels of limonin and higher levels of thymine and epinephrine in the OLP_DM group compared to the OLP. Limonin was negatively correlated with lesion severity, whereas thymine and epinephrine showed positive correlations with both lesion severity and pain scores. The study provides comprehensive evidence of oral microbial dysbiosis and metabolic disturbances in patients with OLP concomitant with T2DM. The findings suggest an interplay between specific bacterial populations and metabolic alterations in the progression and severity of OLP concomitant with diabetes.\n\nID: 42394846\nTitle: Rapid and quantitative phage susceptibility test by ramanome.\nAbstract: Antimicrobial resistance poses an escalating global threat, renewing interest in bacteriophage therapy as a precision alternative to antibiotics. However, clinical translation remains hindered by the lack of rapid and quantitative phage susceptibility testing (PST) platforms capable of evaluating host range, infection potency, and effective multiplicity of infection (MOI). Here, we present a ramanome-based phage susceptibility test (RPST), a phenotypic platform that captures infection-induced remodeling of bacterial macromolecular composition to unify these diagnostic requirements within a single workflow. RPST integrates four Raman biomarkers into a Composite Infection Index (CII), enabling rapid and lysis-independent discrimination between susceptible and resistant bacterial populations within ~1\u2009h, with 96.0% categorical concordance (24/25) to plaque assays. As a continuous population-level metric, CII quantifies the proportion of infected cells, allowing quantitative ranking of phage potency against shared hosts. By resolving CII trajectories across the MOI and time, RPST further determines the minimal effective MOI, which is the lowest phage-to-bacterium ratio sustaining self-propagating infection, thereby defining the lower boundary for therapeutic feasibility. Together, these capabilities transform PST from static compatibility assays into a dynamic and quantitative framework that bridges in vitro infectivity assessment and infection dynamics relevant to phage therapy.\n\nID: 42392447\nTitle: Aztreonam-Avibactam and Cefiderocol against Metallo-\u03b2-Lactamase-Producing Enterobacterales and Other Carbapenem-Resistant Gram-Negative Pathogens: Microbiological Activity and Clinical Evidence.\nAbstract: Aztreonam-avibactam (ATM-AVI) and cefiderocol (CFDC) are two next-generation antibiotics that exhibit promising in vitro activity against metallo-\u03b2-lactamase (MBL)-producing carbapenem-resistant Enterobacterales (CRE). However, differences in antibacterial spectra and resistance mechanisms among clinically important Gram-negative bacteria (GNB) between these two agents remain incompletely understood. English-language publications indexed in PubMed (1990-2026), records retrieved from Google Scholar, and the 2018-2024 Antimicrobial Testing Leadership and Surveillance database were extensively reviewed to assess their potential clinical utility. ATM-AVI demonstrates broad activity against KPC-, MBL-, and OXA-48/181-like-producing CRE. However, ATM-AVI non-susceptibility occurs in Escherichia coli and Providencia rettgeri isolates harboring blaCMY, penicillin-binding protein 3 (PBP3) modifications, and porin dysfunction or acrA efflux overexpression. In contrast, CFDC activity is primarily compromised by NDM production, reduced expression of iron transporters, and PBP3 alterations. Significant regional variation in CFDC susceptibility among MBL-producing CRE isolates collected in Asia and North America/Europe has been observed. Based on limited pooled real-world treatment experience, CFDC shows moderate efficacy (73%) for the treatment of infections caused by MBL-producing CRE. Both antibiotics also show potential in vitro activity against ceftazidime-avibactam-resistant, non-carbapenemase-producing CRE. Notably, CFDC exhibits excellent in vitro activity against contemporary CR-Pseudomonas aeruginosa, most CR-Acinetobacter baumannii harboring blaOXA-23/24/58 genes, Elizabethkingia anophelis, Stenotrophomonas maltophilia, Burkholderia cepacia, and Burkholderia pseudomallei. Nevertheless, CFDC heteroresistance is most prevalent among CR-A. baumannii isolates. Continued assessment of clinical treatment experience with these two antibiotics against MBL-producing CRE and important non-fermenting GNB is warranted to accumulate further evidence regarding their therapeutic roles.\n\nID: 42391045\nTitle: Biosynthesis of glycosylated 5-hydroxycytosine in the DNA of diverse viruses.\nAbstract: Characterizing viral strategies for circumventing cellular defenses is critical to understanding the biology and therapeutic application of bacteriophages as antimicrobials. Many bacteriophages synthesize complex modifications (i.e. hypermodifications) to the nucleobases of their virion DNA in order to circumvent the endonuclease-based defenses of their hosts. To date, most hypermodified pyrimidines in viruses are synthesized via group transfer to a pre-existing hydroxyl moiety in DNA during the later stages of lytic development leading up to packaging of the viral chromosome into the capsid. Typically, these occur at hydroxymethylcytosine or hydroxymethyluracil. We find mono- and poly-arabinosylated cytidines completely replacing canonical cytidine in the native DNA of the Escherichia phage RB69 and Acinetobacter baumannii phage DLP3. In both cases, an arabinosyl moiety is connected directly to the pyrimidine through an ether linkage, with the bridging oxygen originating from 5-hydroxycytosine (5hoC) in DNA. The 5hoC is synthesized as a mononucleotide by a virally encoded thymidylate synthase homolog. We find diverse virally encoded thymidylate synthase homologs, including the Rhizobium phage RL38J1, are capable of producing 5hoC, suggesting this base modification is a starting point for glycodiverse cytosine derivatives. Characterizing these cytosine derivatives adds to our understanding of viral anti-defense mechanisms.\n\nID: 42379827\nTitle: Comparative evaluation of EUCAST RAST and QuickMIC for rapid antimicrobial susceptibility testing of carbapenem-resistant organisms directly from positive blood cultures.\nAbstract: Rapid availability of phenotypic susceptibility results is crucial for the timely detection of multidrug-resistant Gram-negative organisms. Several novel methods have been introduced that enable direct antimicrobial susceptibility testing (AST) from positive blood cultures. This study aimed to assess the analytical performance of the agar diffusion-based EUCAST rapid AST (RAST) method and the automated QuickMIC system using a challenging collection of highly resistant Gram-negative organisms. One hundred one Gram-negative bacteria (Escherichia coli, n = 24; Klebsiella pneumoniae, n = 22; Acinetobacter baumannii, n = 30; and Pseudomonas aeruginosa, n = 25) were spiked into blood cultures and processed according to the respective AST protocols. Broth microdilution (BMD) was performed as the reference method. Time to result (TTR), categorical agreement (CA), and essential agreement (EA) with BMD were evaluated. Boruta analysis was applied to identify genetic determinants associated with AST errors. Overall TTR for QuickMIC was 3 h 44 min with a CA of 86.2% and an EA of 92.3% for Enterobacteriaceae and 97.0% for non-fermenters. Overall CA of RAST ranged from 90.7% to 93.7% across reading time points. Overall, very major discrepancy rates were low (QuickMIC, n = 0.7%, and RAST, n = 0.1%). Presence of NDM-5 and KPC was most frequently associated with errors for QuickMIC and EUCAST RAST, respectively. Both rapid AST approaches yielded rapid and robust results in this diverse and highly resistant bacterial study population. These findings underscore the potential of rapid AST methods to facilitate timely optimization of antimicrobial therapy in bloodstream infections, even in the context of extensively drug-resistant pathogens.IMPORTANCEAccurate antimicrobial susceptibility testing (AST) is essential for stewardship and effective therapy, especially as rising antimicrobial resistance increases the risk of empiric treatment failure. Traditional AST methods are limited by slow turnaround times, creating a need for rapid alternatives. This study evaluated the diagnostic accuracy of two rapid AST (RAST) methods-EUCAST RAST and QuickMIC-using 101 genetically characterized, carbapenem-resistant Enterobacterales, Pseudomonas aeruginosa, and Acinetobacter baumannii tested directly from positive blood cultures. Broth microdilution served as the reference. Both rapid assays provided results within 3.5-6 h and demonstrated high categorical and essential agreement with few very major discrepancies. Incorrect results were more common in isolates harboring NDM-5 and KPC carbapenemases. Overall, the findings support EUCAST RAST and QuickMIC as reliable tools for challenging resistant pathogens and highlight their potential to enable earlier detection of carbapenem-resistant phenotypes and more timely initiation of appropriate, last-resort antimicrobial therapy.\n\nID: 42377799\nTitle: A non\u2011natural shortcut biosynthetic route enables de novo\u00a0microbial production of 3\u2011hydroxyanthranilic and quinolinic acids.\nAbstract: 3\u2011Hydroxyanthranilic acid (3\u2011HAA) and quinolinic acid (QA) are central metabolites of the kynurenine pathway with broad biomedical and industrial relevance, yet their microbial production remains limited by long pathways and rate-limiting enzymes. Here, we report the rational design and validation of a non\u2011natural shortcut pathway enabling de novo biosynthesis of 3\u2011HAA and QA in Escherichia coli. The pathway begins from anthranilic acid (AA), a chorismate\u2011derived intermediate that can be efficiently overproduced. Regioselective 3-hydroxylation of AA was achieved using an FAD-dependent monooxygenase HpaH from Geobacillus thermodenitrificans, supported by a dedicated FAD reductase (GTNG_3158) essential for efficient cofactor regeneration. The resulting 3\u2011HAA was subsequently converted to QA through oxidative ring cleavage by NbaC from Pseudomonas fluorescens, followed by spontaneous cyclization. Through enzyme expression tuning, precursor availability enhancement, and fermentation optimization, the engineered strains produced 2.17\u00a0g/L 3\u2011HAA and 2.04\u00a0g/L QA from glucose in shake flasks, representing the highest reported microbial 3\u2011HAA titer and demonstrating the efficient extension of the artificial pathway to QA production. This work establishes a concise and productive biosynthetic strategy, enabling sustainable and high\u2011level microbial production of 3-HAA\u2011derived compounds.\n\nID: 42375011\nTitle: The Screening, Identification, and Efficient Nitrogen Removal Performance of a Novel Heterotrophic Nitrifying-Aerobic Denitrifying Pseudomonas sp. L5.\nAbstract: A novel bacterium with heterotrophic nitrification-aerobic denitrification (HN-AD) capability, designated Pseudomonas sp. L5, was isolated from the activated sludge of an aerobic denitrification reactor in our laboratory and subsequently identified. This strain can efficiently conduct nitrogen metabolism using NH4 +-N, NO3 --N and NO2 --N as nitrogen sources. Single-factor experiments combined with response surface methodology (RSM) were used to optimize the culture conditions of strain L5. The predicted optimal conditions for growth and nitrogen removal were a C/N ratio of 31.29, sodium acetate as the carbon source, a temperature of 31.18\u00b0C, and an initial pH of 7.25. Notably, even under mildly alkaline conditions (pH\u20099.0), the strain maintained high aerobic denitrification efficiency, with a NO3 --N removal rate of 86.236%. The nitrogen metabolism pathway of strain L5 was elucidated through a combined analysis of the expression of key HN-AD genes and enzyme activities. The denitrification capacity of strain L5 under alkaline conditions provides a theoretical basis and technical support for the application of aerobic denitrifying bacteria in high-pH wastewater treatment.\n\nID: 42369712\nTitle: [Characteristics of the Pathogenic Bacteria Isolated from the Lower Respiratory Tract of the Patients With Acute Exacerbation of Chronic Obstructive Pulmonary Disease].\nAbstract: To analyze the species distribution and in vitro susceptibility of pathogenic bacteria isolated from the lower respiratory tract of the patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), and to provide guidance for the treatment of pulmonary infections in this kind of patients. The AECOPD patients with suspected lower respiratory tract sample infection from January 2015 to December 2024 were included. The data of species identification and in vitro drug susceptibility testing results of pathogenic bacteria isolated from the lower respiratory tract were retrospectively collected. The detection rate, species distribution, in vitro susceptibility of predominant species, and ratios of multidrug-resistant (MDR) bacteria were compared among different sample types. Data were analyzed using WHONET 5.6 and SPSS 26.0 software. A total of 25253 lower respiratory tract samples from 3861 patients were included. The pathogen detection rates in sputum, aspirates and bronchoalveolar lavage fluids were 27.2% (6463/23722), 33.5% (135/403), and 48.9% (551/1128), respectively, with a statistically significant difference of detection rate (P < 0.001). Among the 3,824 non-repetitive strains, the ratio of the isolates recovered from outpatients and emergency patients to those from inpatients is 1\u22366, and the ratio of the isolates from intensive care unit patients to those from other units is 1\u22367. Gram-negative bacteria accounted for 93.1%, with the predominant species including Acinetobacter baumannii complex (23.7%), Pseudomonas aeruginosa (21.4%), Klebsiella pneumoniae (12.6%), Stenotrophomonas maltophilia (11.7%), and Escherichia coli (4.6%). Gram-positive bacteria accounted for 6.9%, with Staphylococcus aureus was the most common species (3.2%). Fastidious bacteria accounted for 6.4%, including Haemophilus influenzae (3.9%), Moraxella catarrhalis (1.6%), and Streptococcus pneumoniae (0.9%). The detection rate of methicillin-resistant S. aureus (MRSA) was 41.8%. The detection rates of carbapenem-resistant E. coli, K. pneumoniae, A. baumannii complex, and P. aeruginosa were 12.0% (21/175), 18.1% (87/480), 69.9% (635/908), and 29.3% (240/819), respectively. Compared with sputum, non-sputum specimens showed a higher detection rate of MDR bacteria (P < 0.01). Gram-negative bacteria were the predominant pathogenic bacteria detected from the low respiratory tract of AECOPD patients, with a low isolation rate of fastidious bacteria. Non-sputum samples exhibited a higher detection rate of MDR bacteria. \u5206\u6790\u4ece\u6162\u6027\u963b\u585e\u6027\u80ba\u75c5\u6025\u6027\u52a0\u91cd\u671f\uff08acute exacerbation of chronic obstructive pulmonary disease, AECOPD\uff09\u60a3\u8005\u4e0b\u547c\u5438\u9053\u5206\u79bb\u75c5\u539f\u83cc\u7684\u83cc\u79cd\u5206\u5e03\u53ca\u4f53\u5916\u836f\u7269\u654f\u611f\u6027\uff0c\u4e3a\u8be5\u7c7b\u60a3\u8005\u4e0b\u547c\u5438\u9053\u611f\u67d3\u6cbb\u7597\u63d0\u4f9b\u53c2\u8003\u3002 \u7eb3\u51652015\u5e741\u6708\u20132024\u5e7412\u6708AECOPD\u7591\u4f3c\u53d1\u751f\u4e0b\u547c\u5438\u9053\u611f\u67d3\u7684\u60a3\u8005\uff0c\u56de\u987e\u6027\u6536\u96c6\u4ece\u4e0b\u547c\u5438\u9053\u6837\u672c\u5206\u79bb\u7684\u75c5\u539f\u83cc\u83cc\u79cd\u9274\u5b9a\u548c\u4f53\u5916\u836f\u7269\u654f\u611f\u6027\u68c0\u6d4b\u7ed3\u679c\uff0c\u5bf9\u6bd4\u5206\u6790\u4e0d\u540c\u7c7b\u578b\u6837\u672c\u7684\u75c5\u539f\u83cc\u68c0\u51fa\u7387\u3001\u83cc\u79cd\u5206\u5e03\u3001\u4e3b\u8981\u83cc\u79cd\u4f53\u5916\u836f\u7269\u654f\u611f\u6027\u548c\u591a\u91cd\u8010\u836f\u83cc\u68c0\u51fa\u60c5\u51b5\u3002\u91c7\u7528WHONET 5.6\u548cSPSS 26.0\u8f6f\u4ef6\u5206\u6790\u6570\u636e\u3002 \u7eb3\u5165\u76843861\u4f8b\u60a3\u8005\u9001\u68c0\u4e0b\u547c\u5438\u9053\u6837\u672c25253\u4efd\uff0c\u75f0\u6db2\u3001\u6c14\u9053\u5206\u6ccc\u7269\u548c\u80ba\u6ce1\u704c\u6d17\u6db2\u7684\u75c5\u539f\u83cc\u68c0\u51fa\u7387\u5206\u522b\u4e3a27.2%\uff086463/23722\uff09\u300133.5%\uff08135/403\uff09\u548c48.9%\uff08551/1128\uff09\uff0c\u68c0\u51fa\u7387\u5dee\u5f02\u6709\u7edf\u8ba1\u5b66\u610f\u4e49\uff08P<0.001\uff09\u3002\u5171\u5206\u79bb\u5230\u975e\u91cd\u590d\u83cc\u682a3824\u682a\uff0c\u95e8\u6025\u8bca\u60a3\u8005\u548c\u4f4f\u9662\u60a3\u8005\u6765\u6e90\u7684\u7ec6\u83cc\u6570\u91cf\u6bd4\u4e3a1\u22366\uff0c\u91cd\u75c7\u76d1\u62a4\u75c5\u623f\u548c\u5176\u4ed6\u75c5\u623f\u6765\u6e90\u7684\u7ec6\u83cc\u6570\u91cf\u6bd4\u4e3a1\u22367\u3002\u5206\u79bb\u682a\u4ee5\u9769\u5170\u9634\u6027\u83cc\u4e3a\u4e3b\uff0893.1%\uff09\uff0c\u9c8d\u66fc\u4e0d\u52a8\u6746\u83cc\u590d\u5408\u7fa4\u68c0\u51fa\u7387\u6700\u9ad8\uff0823.7%\uff09\uff0c\u5176\u6b21\u4e3a\u94dc\u7eff\u5047\u5355\u80de\u83cc\uff0821.4%\uff09\u3001\u80ba\u708e\u514b\u96f7\u4f2f\u83cc\uff0812.6%\uff09\u3001\u55dc\u9ea6\u82bd\u7a84\u98df\u5355\u80de\u83cc\uff0811.7%\uff09\u548c\u5927\u80a0\u57c3\u5e0c\u83cc\uff084.6%\uff09\uff1b\u9769\u5170\u9633\u6027\u83cc\u5360\u6bd4\u4e3a6.9%\uff0c\u4ee5\u91d1\u9ec4\u8272\u8461\u8404\u7403\u83cc\uff083.2%\uff09\u4e3a\u4e3b\uff1b\u82db\u517b\u83cc\u5360\u6bd4\u4e3a6.4%\uff0c\u5305\u62ec\u6d41\u611f\u55dc\u8840\u6746\u83cc\uff083.9%\uff09\u3001\u5361\u4ed6\u83ab\u62c9\u83cc\uff081.6%\uff09\u548c\u80ba\u708e\u94fe\u7403\u83cc\uff080.9%\uff09\u3002\u8010\u7532\u6c27\u897f\u6797\u91d1\u9ec4\u8272\u8461\u8404\u7403\u83cc\u68c0\u51fa\u7387\u4e3a41.8%\uff0851/122\uff09\uff0c\u8010\u78b3\u9752\u9709\u70ef\u7c7b\u7684\u5927\u80a0\u57c3\u5e0c\u83cc\u3001\u80ba\u708e\u514b\u96f7\u4f2f\u83cc\u3001\u9c8d\u66fc\u4e0d\u52a8\u6746\u83cc\u590d\u5408\u7fa4\u548c\u94dc\u7eff\u5047\u5355\u80de\u83cc\u7684\u68c0\u51fa\u7387\u4f9d\u6b21\u4e3a12.0%\uff0821/175\uff09\u300118.1%\uff0887/480\uff09\u300169.9%\uff08635/908\uff09\u548c29.3%\uff08240/819\uff09\u3002\u4e0e\u75f0\u6837\u672c\u76f8\u6bd4\uff0c\u975e\u75f0\u6837\u672c\u7684\u591a\u91cd\u8010\u836f\u83cc\u68c0\u51fa\u7387\u66f4\u9ad8\uff08P<0.01\uff09\u3002 AECOPD\u60a3\u8005\u4e0b\u547c\u5438\u9053\u68c0\u51fa\u75c5\u539f\u83cc\u4e2d\u7edd\u5927\u591a\u6570\u4e3a\u9769\u5170\u9634\u6027\u83cc\uff0c\u82db\u517b\u83cc\u68c0\u51fa\u7387\u8f83\u4f4e\uff0c\u975e\u75f0\u6837\u672c\u7684\u591a\u91cd\u8010\u836f\u83cc\u68c0\u51fa\u7387\u8f83\u9ad8\u3002\n\nID: 42365575\nTitle: Pathogens in the bay: environmental Staphylococcus saprophyticus strains mirror clinical counterparts in virulence, biofilm formation, antimicrobial resistance, pathogenicity, and phage susceptibility.\nAbstract: Staphylococcus saprophyticus is a leading cause of urinary tract infections, yet little is known about its environmental reservoirs and traits outside clinical settings. This study aimed to compare clinical and environmental S. saprophyticus strains isolated from a polluted coastal ecosystem in Brazil, assessing their virulence-associated traits, antimicrobial resistance, biofilm formation, and susceptibility to bacteriophages. Forty strains (20 clinical, 20 environmental) were characterized using GTG5-PCR, virulence gene screening, antibiotic susceptibility testing, biofilm assays, exposure to sub-inhibitory concentrations of ciprofloxacin, Tenebrio molitor infection model, and phage activity tests. Genetic fingerprinting and virulence gene profiles revealed a high degree of similarity between environmental and clinical isolates, indicating the presence of shared virulence-associated determinants. Environmental strains exhibited resistance to multiple antibiotics and showed biofilm formation and larval survival patterns comparable to those observed for clinical isolates. Exposure to sub-inhibitory concentrations of ciprofloxacin increased biofilm formation in several strains. Bacteriophage CSF, originally isolated from swine farm effluent, displayed lytic and antibiofilm activity against a substantial proportion of the isolates. These findings highlight the presence of clinically relevant traits among environmental S. saprophyticus strains and underscore the importance of continued microbiological surveillance in anthropized aquatic environments.\n\nID: 42364026\nTitle: Beyond minimum inhibitory concentration values: clinical and diagnostic challenges of colistin heteroresistance in Acinetobacter baumannii.\nAbstract: In recent years, infections caused by multidrug-resistant and particularly carbapenem-resistant Gram-negative bacteria have become a major global public health concern. In this context, the progressive limitation of therapeutic options has led to the reintroduction of polymyxin antibiotics, such as colistin, into clinical practice as last-resort agents. However, the widespread use of colistin has been accompanied by an increasing incidence of resistance, among which heteroresistance has emerged as a significant challenge for both diagnosis and treatment. Heteroresistance is defined as the presence of subpopulations within a bacterial isolate that exhibit varying levels of susceptibility to a given antibiotic. In Acinetobacter baumannii, colistin heteroresistance may result in the selection and expansion of resistant subpopulations during therapy, contributing to clinical failure, persistent infections, and recurrence. Furthermore, the inability of routine antimicrobial susceptibility testing methods to reliably detect heteroresistance may lead to its underrecognition in clinical settings, potentially resulting in inappropriate therapeutic decisions. Current evidence indicates that the prevalence of colistin heteroresistance in A. baumannii varies geographically. The findings presented in this review highlight the importance of increasing awareness of the molecular basis and clinical implications of colistin heteroresistance in A. baumannii, and emphasize the need for improved diagnostic approaches and more effective treatment strategies for both microbiologists and clinicians.\n\nID: 42363638\nTitle: Inhalable bacteriophage endolysins: a novel therapeutic strategy for drug-resistant bacterial pulmonary infections - a comprehensive review.\nAbstract: Pulmonary infections caused by multidrug-resistant (MDR) bacteria pose a severe global health threat with high mortality rates, especially in hospital-acquired pneumonia. The stagnation of new antibiotic development underscores the urgent need for alternative therapeutics. This review summarizes recent advances in the application of bacteriophage endolysins against major MDR respiratory pathogens, including Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae. We focus on their mechanisms of action, synergistic effects with antibiotics, and efficacy against biofilms. Endolysins demonstrate potent and species-specific lytic activity against a broad spectrum of MDR bacteria. A key advantage is their low propensity for inducing resistance. Critically, when administered via optimized inhalation delivery systems, endolysins can achieve high local concentrations in the lungs - though this depends on factors such as the aerosol device, formulation properties and patient-related variables - effectively eradicating pathogens in animal models of pneumonia with minimal systemic toxicity. This direct pulmonary delivery approach bypasses many challenges associated with systemic administration and enhances therapeutic outcomes. Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections. Their rapid lytic activity, synergy with conventional antibiotics, and suitability for inhalable formulation position them as a potent adjunct or alternative therapy. While challenges in stabilization and large-scale production remain, advancing inhalation delivery systems for endolysins holds immense potential to holds immense potential to revolutionize the treatment of recalcitrant respiratory infections.\n\nID: 42363205\nTitle: Epidemiological trends of multidrug-resistant organisms in a tertiary-care pediatric hospital, 2017-2023.\nAbstract: Antimicrobial resistance (AMR) is a growing global threat, particularly for children under 5 years. This study is aimed to investigate temporal trends and describe the epidemiological characteristics of MDR bacteria isolated in hospitalized children from 2017 to 2023 in an academic children's hospital in Italy. We included all bacterial isolates obtained from blood or cerebrospinal fluid (CSF) cultures collected from pediatric patients evaluated in both inpatient settings and the Emergency Department between 1 January 2017 and 31 December 2023. The study included the main ESKAPE pathogens (including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) and other relevant MDROs such as Escherichia coli. Data were extracted from the hospital microbiology data warehouse, and resistance proportions were calculated as MDR isolates over total isolates for each pathogen. Associations between year, patient characteristics, ward type, and MDRO infections were evaluated using univariable and multivariable logistic regression; trends over time were evaluated using the Cochrane-Armitage test for categorical variables. Out of 51,886 blood or CSF cultures, 1,528 (2.9%) were positive for microorganisms of interest, and 211 (13.8%) were MDROs. The highest resistance proportions were observed in Carbapenems-Resistant Pseudomonas Aeruginosa/Pseudomonas Aeruginosa (CRPA/PA, 52.8%), followed by Methicilln-Resistant Staphylococcus Aureus/Staphylococcus Aureus (MRSA/SA, 36.7%), Carbapenem-Resistant Klebsiella Pneumoniae/Klebsiella Pneumoniae (CRKP/KP, 12.6%), and Vancomycin-Resistant Enterococcus (VRE)/Enterococcus (VRE/E, 11.5%). Significant reductions were recorded for MRSA/SA (43.5% in 2017 to 25.7% in 2023; p\u2009=\u20090.001) and CRPA/PA (85.0% to 47.1%; p\u2009<\u20090.001), while CRKP/KP and VRE/E showed no significant temporal trends. Neonatology and PICU showed higher odds for MRSA isolation (p\u2009<\u20090.001) compared to medical wards. Onco-hematology displayed an adjusted OR of 3.0 (95% CI: 1.2-7.7) for VRE. Year was independently associated with CRPA, with adjusted ORs of 0.03 and 0.14 in 2020 and 2021 (p\u2009<\u20090.01) compared to 2017. Understanding local AMR patterns remains essential for guiding empirical therapy across heterogeneous hospital settings.\n\nID: 42357387\nTitle: Towards the Synthesis of Pyoverdines: Preparation and Reactivity of the N-Formylhydroxyornithine Residue.\nAbstract: The Gram-negative bacterium Pseudomonas aeruginosa produces a family of peptide siderophores called pyoverdines that play a vital role in the mechanisms by which it acquires iron from the environment. A key component of various pyoverdines is the presence of one or more copies of L-\u03b4-N-formyl-\u03b4-N-hydroxyornithine (fOHOrn) as an iron-binding residue. In this study, we have developed an improved preparation of a derivative of fOHOrn that is suitable for use in solid-phase peptide synthesis, incorporating a novel N-oxidation protocol and a mild final deprotection with HCl/hexafluoroisopropanol (HFIP) that circumvents the unexpected deformylation of the fOHOrn side chain under acidic conditions. We have also devised a synthesis of the cyclic peptide component of pyoverdine D exploiting a selective side-chain deprotection strategy with HCl/HFIP that allows the application of readily available amino acids with standard tert-butyl side-chain protection and which facilitates the cyclisation step. These innovations open the way towards the convergent preparation of various pyoverdines and also other natural products that contain fOHOrn residues.\n\nID: 42353706\nTitle: Antimicrobial Resistance and Clinical Outcome Among Hospitalized Bacterial Pneumonia: A Retrospective Cohort Study in Indonesian Tertiary Hospital.\nAbstract: Background: Pneumonia is a common cause of hospitalization and a significant contributor to worldwide morbidity and mortality. Effective definitive antimicrobial therapy for pneumonia relies on accurate identification of bacterial pathogens and their resistance patterns. Therefore, this study aims to evaluate the distribution bacterial pathogens and their antimicrobial resistance patterns, as well as clinical factors associated with outcomes among hospitalized pneumonia patients. Methods: This retrospective cohort study was conducted at Dr. Hasan Sadikin General Hospital, Indonesia, and included adult patients hospitalized with pneumonia between January and December 2024. Clinical, demographic, microbiological, and outcome data were extracted from electronic medical records and the laboratory system. Bacterial distribution, antimicrobial patterns, and clinical outcomes were analyzed descriptively and compared across pneumonia types. Multivariable regression analyses were performed to identify factors associated with in-hospital mortality and length of hospital stay. Results: A total of 662 hospitalized pneumonia patients were included with Gram-negative bacteria (i.e., Klebsiella pneumonia, Acinetobacter baumannii, and Pseudomonas aeruginosa) identified as the most common pathogens. Carbapenem-resistant Acinetobacter baumannii (CR-Ab) and Klebsiella pneumoniae (CR-Kp) were the most frequently identified resistant pathogens, particularly in hospital-acquired (HAP) and ventilator-associated pneumonia (VAP). HAP and VAP were independently associated with higher in-hospital mortality and longer hospital stay compared to community-acquired pneumonia (CAP). In addition, CR-Ab and difficult-to-treat Pseudomonas aeruginosa (DTR-Psa) were associated with prolonged hospitalization. Conclusions: Type of pneumonia, bacterial pathogens and resistance patterns were associated with in-hospital mortality and length of hospital stay. These findings highlight the importance of ongoing microbiological surveillance, antimicrobial stewardship, and infection prevention strategies to optimize pneumonia management and clinical outcomes.\n\nID: 42353674\nTitle: The ESKAPE Challenge: Understanding Resistance and Exploring Alternative Treatments.\nAbstract: Antimicrobial resistance (AMR) constitutes a critical and escalating global public health challenge, severely limiting the potential of existing antimicrobial drugs and escalating infection-associated morbidity and mortality rates. This analysis focuses on the ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species), which are prioritized by the World Health Organization (WHO) and represent a significant cause of nosocomial infections due to their extensive drug resistance. We provide an in-depth review of the global prevalence and specific antibiotic-resistant mechanisms of these pathogens. Due to the decline in the traditional antibiotic development pipeline, accelerated development of alternative therapeutic strategies is essential. The review comprehensively discusses innovative non-traditional therapies currently being explored to bypass traditional antibiotic limitations, such as phage therapy, antimicrobial peptides (AMPs), anti-virulence therapies, fecal microbiota transplantation (FMT), and targeted CRISPR-based approaches. Addressing the ESKAPE challenge requires a concerted, multi-sectoral strategy guided by the One Health principle, focusing on enhancing public awareness, improving surveillance and research, optimizing judicious antibiotic use, and cultivating sustainable investment in novel interventions.\n\nID: 42353666\nTitle: Role of Mobilome in Carbapenem Resistance.\nAbstract: Growing resistance to carbapenem antibiotics is a major public health problem as these antibiotics are considered the last line of therapy for infections caused by multidrug-resistant (MDR) Gram-negative bacteria. The rapid emergence and dissemination of carbapenem-resistant bacterial strains are mainly due to horizontal gene transfer (HGT) within or between bacterial cells via the mobilome. The aim of this article is to discuss the role of mobile genetic elements (MGEs) that capture and disseminate resistance determinants of carbapenem antibiotics, as a comprehensive review integrating the combined role of plasmids, transposons and integrons. It attempts to systematically fill the gap by investigating the role of these MGEs in the acquisition, mobilization and dissemination of genes encoding carbapenemases across clinically important bacteria. Various types of plasmids such as IncF and IncH in Klebsiella pneumoniae, IncL/M in Enterobacter cloacae, IncX3 in Escherichia coli and IncA/C2 in Salmonella enterica carry important genes encoding carbapenemases. The rapid distribution of transposons among bacterial species is one of the main contributing factors in the dissemination of carbapenem-resistant isolates. Transposons including Tn4401 carrying blaKPC in K. pneumoniae and Tn1721 carrying blaKPC in E. coli; Tn2006, Tn2007, Tn2008 and Tn2009 carrying blaOXA-23 in Acinetobacter baumannii; Tn1696 carrying blaIMP-4 in Pseudomonas aeruginosa; Tn125 carrying blaNDM in E. coli; and Tn6306 carrying blaIMI in Raoultella ornithinolytica encode different types of carbapenemases. Integrons mainly belonging to class 1 capture resistance determinants for metallo-carbapenemases such as NDM-, VIM-, SIM- and IMP-type enzymes in P. aeruginosa, A. baumannii, K. pneumoniae and E. coli and can promote the transcription and expression of these determinants. These findings are useful for understanding the genetics of carbapenem resistance and additional knowledge on MGEs may provide avenues for screening of resistance to these antibiotics in clinical settings.\n\nID: 42353125\nTitle: Integrative Systems-Level Transcriptomic Network Analysis Identifies Candidate Genes Associated with Biofilm Formation and Virulence in Pseudomonas aeruginosa.\nAbstract: Pseudomonas aeruginosa (P. aeruginosa) is a multidrug-resistant opportunistic pathogen that causes both acute and chronic infections and is known for its ability to form biofilms. In the current study, we applied a hypothesis-generating framework primarily based on integrating four different datasets and applying batch correction. Weighted Gene Co-Expression Network Analysis (WGCNA) was performed in parallel with differential expression analysis using limma. Therefore, we aimed to identify potential biofilm-associated gene candidates. Significant candidate genes were subjected to functional analysis and gene ontology, followed by the construction of a protein-protein interaction network using STRING. The Pseudomonas Genome Database was used to highlight the candidate genes. A total of 271, 687, 533, and 277 significantly up-regulated differentially expressed genes (DEGs), as well as 306, 985, 472, and 312 significantly down-regulated DEGs, resulted from the exploratory analysis. Through WGCNA/limma integration, 223 common significantly up-regulated/positively correlated gene candidates were identified. Functional analysis results showed significant enrichment in virulence-related pathways, such as biofilm formation (PA0083, PA0084, hcp1, hcpC, pilH, pilI, pilJ, vfr, pqsA, pqsB, pqsC, pqsE, PA1657, and PA1658). In addition, other virulence-related pathways, such as quorum sensing, phenazine biosynthesis, the bacterial secretion system, and secondary metabolite biosynthesis, were enriched. In conclusion, our hypothesis-generating integrative analysis identifies candidate genes and potential pathways associated with biofilm formation, virulence, and other processes in P. aeruginosa. In light of this, we point out that all candidate genes presented in this study remain hypothesis-generating. Further validation is recommended, including large-scale in silico analyses and in vitro experimental studies.\n\nID: 42402019\nTitle: Photosynthesis-driven interactions in the phycosphere enhance bacterial extracellular superoxide production.\nAbstract: Extracellular superoxide generated by heterotrophic bacteria influences aquatic redox transformations, yet its regulation within the phycosphere remains poorly understood. Here, we show that the cyanobacterium Microcystis aeruginosa enhances extracellular superoxide production by Pseudomonas sp. QJX-1 under illumination. Cocultivation increased extracellular superoxide production approximately threefold over bacterial monoculture, with maximum enhancement during carbon starvation. Membrane separation localized detectable superoxide production to the bacterial chamber, indicating that diffusible algal products stimulated bacterial superoxide production. Mechanistically, illuminated cocultures showed 20.4% higher photocurrent than algal monocultures and accumulated the highest extracellular NADP(H) levels, indicating intensified photosynthesis-associated extracellular redox activity. Reduced nicotinamide cofactors stimulated diphenyleneiodonium-sensitive QJX-1-associated superoxide production, consistent with an oxidoreductase-associated route for one-electron reduction of molecular oxygen. In parallel, coculture accumulated catecholate siderophores, consistent with intensified microscale Fe competition; this siderophore-enhanced response required metabolically active bacterial cells and was attenuated by respiratory-chain inhibition. Representative extracellular redox-active and algal photoactive components further enhanced the bacterial response, with cytochrome c and chlorophyll a stimulating QJX-1-associated superoxide production under defined conditions. Functionally, during the carbon-starvation interval coinciding with peak superoxide production, the apparent sulfamethoxazole removal rate constant in coculture was 2.6 times that observed for QJX-1 alone. Moreover, quenching extracellular reactive oxygen species impaired metabolic activity under diverse chemical stressors and reduced carbon, nitrogen, and phosphorus substrate utilization. Collectively, these findings identify photosynthesis-dependent phycosphere interactions as regulators of bacterial superoxide production, linking biogenic reactive oxygen species to contaminant transformation, chemical-stress resilience, and elemental nutrient turnover.\n\nID: 42391963\nTitle: Transport specificity of FpvA and FpvB for pyoverdine-antibiotic conjugates in Pseudomonas aeruginosa.\nAbstract: Pyoverdines (PVDs) are fluorescent siderophores produced by many Pseudomonas species. In P. aeruginosa, the TonB-dependent transporters (TBDT) FpvA and FpvB mediate PVD-dependent iron acquisition. PVDs have emerged as promising vectors for antibiotics in antibacterial Trojan horse strategies. However, the uptake of PVD-antibiotic conjugates by FpvA and FpvB remains poorly characterized. Here, we report the semisynthesis of a PVD-oxazolidine conjugate used as a molecular tool to investigate how P. aeruginosa accesses iron via these TBDTs in the presence of two native PVDs and their corresponding antibiotic conjugates. Growth assays demonstrate that P. aeruginosa can access iron chelated by PVDs through both FpvA and FpvB. In contrast, although both antibiotic conjugates provide iron to the strain via FpvA, only one does so via FpvB, indicating differential receptor recognition. Docking analyses reveal that native PVDs adopt similar binding modes within both FpvA and FpvB. However, FpvB-previously described as a broadly selective transporter-exhibits selective restriction toward PVD-antibiotic conjugates. Our results provide insights for the design of PVD-antibiotic conjugates and emphasize the critical role of the conjugation site on PVD in ensuring efficient transporter-mediated uptake.\n\nID: 42390516\nTitle: Prevalence and Antimicrobial Resistance of Non fermenting Gram-negative Bacilli Isolated from Blood Culture Samples in a Tertiary Care Hospital.\nAbstract: Non-fermenting Gram-negative bacilli (NFGNB) are emerging as a significant cause of bloodstream infections (BSIs), a major concern of morbidity and mortality worldwide. The high intrinsic resistance of NFGNB to antimicrobial compounds makes treatment of BSI difficult and expensive. This study aimed to determine the prevalence of NFGNB and the antimicrobial susceptibility pattern of the isolates. A total of 1230 blood culture samples were received in the department of microbiology during the study period of 3 months, which were processed by standard microbiological procedures. Antimicrobial susceptibility tests were performed using Clinical and Laboratory Standards Institute (CLSI) guidelines. Out of 255 (20.73%) positive blood culture samples, 105 (8.5%) Gram-negative bacilli were isolated, of which 41 (3.33%) NFGNB were identified. The most common isolate identified is Pseudomonas aeruginosa (21), followed by Acinetobacter spp. (20). A higher percentage of antibiotic resistance was seen for Acinetobacte r spp. and even higher antibiotics like ceftazidime (87.5%) and gentamicin (92.5%). This study will help us start empirical treatment and implement proper hospital infection control measures.\n\nID: 42371921\nTitle: Establishment of A Mouse Sepsis-Induced Immunosuppression Model By Intranasal Instillation of Bacteria.\nAbstract: Sepsis is a life-threatening organ failure caused by the host's inappropriate response to infection. Pneumonia is the primary cause of sepsis. Animal models are important tools for studying the pathogenesis of sepsis and evaluating new treatment strategies. Previous animal models of sepsis lacked natural infection pathways, making it difficult to accurately reflect the clinical infection process. This study introduced a mouse sepsis immunosuppression model established by intranasal instillation of Klebsiella pneumoniae (KP) to simulate the natural respiratory infection pathway. After modeling with different concentrations of KP, the inflammation of the model was evaluated at 12 h for cytokine interleukin-6 (IL-6) levels, and organ damage was evaluated at 24 h for alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK), and blood urea nitrogen (BUN) levels. The survival rate of the model was analyzed after 7 days. The percentage of lymphocytes and white blood cells, the proportion of major histocompatibility complex class II (MHC-II) expression in monocytes, and the mean fluorescence intensity (MFI) of IL-10 and TGF-\u03b21 in CD4+ T cells were observed to evaluate the immune suppression in mice. After 7 days of modeling, a secondary infection was performed by intranasal instillation of Pseudomonas aeruginosa (PA). The bacterial load in bronchoalveolar lavage fluid (BALF) 24 h after secondary infection and the mortality rate within 14 days were assessed to further evaluate the model's immune suppression. Nasal instillation of high-concentration Klebsiella pneumoniae can effectively induce an immune suppression. Its purpose is to simulate sepsis induced by a natural respiratory infection pathway and to provide a standard model for sepsis research in animals.\n\nID: 42341576\nTitle: Genomic insights and antifungal potential of Pseudomonas species isolated from maple sap, including the novel species Pseudomonas acericola sp. nov. and Pseudomonas edsoni sp. nov.\nAbstract: Fungal contamination poses a significant challenge in maple sap collection systems and postproduction processes, which affects the quality and shelf life of maple syrup. As an alternative to chemical treatments, microorganisms offer promising biocontrol potential. This study investigates nine Pseudomonas strains isolated from maple sap for their antifungal activity and genomic features. Whole-genome sequencing followed by comparative genomic analysis identified five distinct Pseudomonas species, including two previously uncharacterized taxa for which we propose the names Pseudomonas acericola sp. nov. and Pseudomonas edsoni sp. nov., in accordance with the nomenclatural guidelines of the SeqCode. Strain distributions from metagenome recruitment suggest they originate from sapwood, and previous metataxonomic data show that the amplicon sequence variant matching P. edsoni predominated maple sap samples. Genome mining using antiSMASH and BAGEL4 identified gene clusters associated with the synthesis of antifungal compounds, such as hydrogen cyanide, siderophores, cyclic lipopeptides, and ribosomally synthesized peptides. Antifungal assays demonstrated inhibitory activity against food spoilage fungi, with P. edsoni strains being active against Kluyveromyces lactis. The absence of activity in the cell-free supernatant and the presence of Type VI secretion systems in the genomes point toward contact-dependent mechanisms. Collectively, these findings reveal previously unrecognized taxonomic diversity and ecological specialization in maple sap-associated Pseudomonas, providing a basis for the rational development of Pseudomonas-based antifungal strategies in maple syrup production and quality control.\n\nID: 42332574\nTitle: Emergence of blaNDM-1 in Pseudomonas aeruginosa ST308 and ST773 from bloodstream infections in Egypt.\nAbstract: Carbapenem-resistant Pseudomonas aeruginosa (CRPA) remains a significant challenge to clinical management, particularly in critically ill hospitalized patients. The present study aimed to investigate the prevalence and molecular epidemiology of blaNDM-1 among 50 Pseudomonas aeruginosa isolates causing bloodstream infections in cancer patients in Egypt, and to characterize their antimicrobial resistance profiles, carbapenemase production, and biofilm-forming capacity. Antimicrobial susceptibility testing, minimum inhibitory concentrations, multiplex PCR for carbapenemase genes, biofilm assays, and multilocus sequence typing (MLST) were performed. Two representative isolates underwent whole-genome sequencing (WGS) to determine the genetic context of blaNDM-1. All isolates exhibited multidrug-resistant or extensively drug-resistant phenotypes. Carbapenem resistance was detected in 80% (n\u2009=\u200940) of isolates, and blaNDM-1was identified in 64% (n\u2009=\u200932), comprising 80% of carbapenem-resistant isolates. Strong biofilm formation was significantly associated with blaNDM-1 carriage (P\u2009=\u20090.0115). MLST analysis of a subset of blaNDM-1-producing isolates (n\u2009=\u200910) revealed two sequence types among blaNDM-1-producing isolates: ST308 (n\u2009=\u20096) and ST773 (n\u2009=\u20094). These findings indicate the dissemination of high-risk Pseudomonas aeruginosa clones ST308 and ST773 carrying blaNDM-1 in Egypt. WGS showed chromosomal integration of blaNDM-1within integrative and conjugative elements (ICEs) containing IS91-family transposases and multiple additional resistance genes. However, the relatively small sample size and the limited number of isolates subjected to WGS may restrict the generalizability of these findings. The presence of blaNDM-1 within mobile genetic platforms highlights the ongoing evolution and dissemination of CRPA in this clinical setting and calls for enhanced surveillance, as these lineages may act as reservoirs for the acquisition and dissemination of diverse antimicrobial resistance determinants via their putative ICE.\n\nID: 42307240\nTitle: Siderophore sharing protects clonal Pseudomonas aeruginosa biofilms from colistin.\nAbstract: Siderophores mediate cooperative iron acquisition and stress tolerance in polymicrobial communities. However, whether and how such social roles emerge within clonal populations of a single bacterial strain remain unclear. Here, we investigate whether and how such social roles emerge within clonal populations of a single bacterial strain. Using single-cell transcriptomics, we analyzed the response of clonal Pseudomonas aeruginosa PAO1 biofilms to colistin and identified 13 transcriptionally distinct subpopulations, with siderophore biosynthesis genes enriched in one subpopulation. Upon colistin exposure, these genes were specifically upregulated in this subpopulation, whereas their cognate receptor genes were ubiquitously expressed across all subpopulations. Through genetic and physiological experiments, we demonstrate that siderophore sharing between the subpopulations confers cross-protection against colistin by enhancing resistance in a growth-independent manner, as well as by promoting biofilm formation and stability. Therefore, the spontaneous emergence of siderophore producers and non-producer subpopulations, along with their intercellular interaction mediated by siderophore sharing, constitutes a strategy for colistin protection.IMPORTANCEThis work provides a single-cell transcriptomic atlas of P. aeruginosa biofilms and reveals transcriptional heterogeneity within the clonal population. Colistin treatment markedly reshaped the subpopulation structure, with a siderophore biosynthesis-related subpopulation being significantly enriched, while siderophore receptor genes were broadly expressed across all subpopulations. This pattern of \"production specialization\" and \"reception universalization\" extends the applicability of public goods theory to clonal bacterial populations at the single-cell level and further reveals the important role of siderophore sharing in mediating cross-protection among genetically identical subpopulations. These findings deepen our understanding of the complexity of bacterial behaviors and provide potential therapeutic targets for combating biofilm-associated infections.\n\nID: 42303529\nTitle: The \"Trojan horse\" against antimicrobial resistance: Siderophore conjugates and public health.\nAbstract: Antimicrobial resistance, particularly in carbapenemase-producing Enterobacterales such as KPC-type, represents a critical threat to public health in Latin America, associated with high mortality rates and increased healthcare costs. This systematic review aims to evaluate the therapeutic potential of siderophore-drug and siderophore-peptide conjugates against priority multidrug-resistant pathogens, including Enterobacterales, Pseudomonas aeruginosa, and Acinetobacter baumannii, analyzing their efficacy, mechanisms of action, and implementation challenges. A systematic search was conducted in PubMed, Scopus, and Web of Science databases up to August 2025, using key terms such as \"siderophore conjugates\", \"Trojan horse antibiotics\", \"antimicrobial resistance\", and \"Gram-negative bacteria\". Preclinical and clinical studies, reviews, and meta-analyses published between 2019 and 2025 were included, selecting 55 references based on relevance to the topic, currency, and methodological quality. This review corresponds to a narrative review with a systematic literature search, developed in accordance with PRISMA guidelines. Siderophore conjugates, via the \"Trojan horse\" mechanism, effectively exploit bacterial iron uptake systems to deliver antimicrobial agents in a targeted manner. They overcome key resistance mechanisms such as \u03b2-lactamase production, porin alterations, and efflux pump activity, while reducing systemic toxicity and preserving commensal microbiota. Clinical evidence (e.g., cefiderocol) and preclinical studies confirm efficacy against multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains, with significant reductions in minimum inhibitory concentrations (MICs). However, critical challenges were identified: optimization of chemical stability and intracellular drug release, complexity in synthesis and industrial scaling under Good Manufacturing Practice (GMP) standards, and regulatory and logistical barriers in resource-limited settings. Siderophore conjugates offer a targeted therapeutic approach against multidrug-resistant pathogens by exploiting the bacteria's own iron-uptake systems. Available evidence ranges from clinical results with cefiderocol to preclinical developments with other platforms. Their application, however, faces challenges that span chemical optimization, manufacturing, regulation, and access in clinical settings.\n\nID: 42295605\nTitle: Genome-wide analysis of biosynthetic gene clusters reveals hidden metabolic diversity in bacterial fish pathogens.\nAbstract: Fish-pathogenic bacteria threaten global aquaculture, yet their biosynthetic capacity for secondary metabolites remains unexplored at the genomic scale. We present the first cross-genus atlas of biosynthetic gene clusters (BGCs) in prokaryotic fish pathogens, analyzing 1,855 genomes across 12 families and 14 genera. Using antiSMASH and BiG-SCAPE, we identified 13,626 BGCs encoding NRPS, PKS, RiPPs, terpenes, and siderophores, organized into 2,842 gene cluster families. Strikingly, 1,724 families (61%) lack close MIBiG reference homologs (designated here as MIBiG-distant clusters), representing potentially underexplored enzymatic diversity. Genus-level analyses revealed pronounced specialization: Pseudomonas, Mycobacterium, and Nocardia harbor NRPS/PKS-rich repertoires (>\u20095 BGCs/genome), while Streptococcus and Enterococcus exhibit streamlined RiPP-dominated profiles. Network analysis identified cross-taxon BGC sharing patterns consistent with horizontal gene transfer among aquatic lineages and massive within-genus expansions, with Flavobacterium RiPP families averaging 69 members. Genome-wide correlations linked GC content to BGC density (r\u2009=\u20090.41, p\u2009<\u20090.001), with genus-specific relationships ranging from r\u2009=\u20090.77 (Chryseobacterium) to r\u2009=\u2009-0.84 (Lactococcus), revealing compositional constraints on metabolic evolution. BGC distribution patterns reflected ecological lifestyle and suggested potential roles in iron acquisition, interspecies competition, and host colonization. This molecular inventory establishes fish-pathogenic bacteria as a strategic frontier for natural product discovery, providing a phylogenetically resolved roadmap for isolating antimicrobials, siderophores, and biofilm modulators with applications in sustainable aquaculture disease management.\n\nID: 42294726\nTitle: Systematic combinatorial optimization of three-phage cocktails against multidrug-resistant Pseudomonas aeruginosa.\nAbstract: Multidrug-resistant (MDR) Pseudomonas aeruginosa poses a significant global health threat, necessitating alternative therapeutic strategies. Bacteriophage therapy shows promise, but single-phage use is prone to resistance. Bacteriophage cocktails can address this issue, but they are typically formulated empirically without a systematic evaluation of constituent phage interactions. We employed a comprehensive combinatorial approach to optimize three-phage cocktails against clinical P. aeruginosa isolates. From 25 candidate bacteriophages, 5 were selected based on a broad host range (\u226560% of 51 MDR P. aeruginosa clinical isolates). Ten possible three-phage cocktail combinations were systematically generated and evaluated using real-time Omnilog phenotypic microarray analysis. Phage interactions were quantified using the Highest Single Agent independence model to classify synergistic (\u0394 > +5%), neutral (-5% \u2264 \u0394 \u2264 +5%), or antagonistic (\u0394 < -5%) effects. Individual phage inhibition efficiencies ranged from 35.4% to 75.4%. Cocktail performance varied dramatically (16.1%-84.1% inhibition). Only one cocktail exhibited synergy, achieving 84.1% inhibition, an 8.7% improvement over the best individual phage. Four cocktails (40%) showed neutral interactions, while five (50%) demonstrated antagonistic effects. The optimal cocktail (Phages 1 + 3 + 4) demonstrated efficacy across six of eight diverse clinical isolates in biofilm inhibition assays (29%-63% biomass reduction, 2.7-3.6 log10 colony-forming unit reduction) and achieved 80% survival in Galleria mellonella versus 10% in infected controls. These findings demonstrate that phage cocktail optimization requires rational validation, as antagonistic interactions can occur, establishing a critical validation step before committing resources to in vivo efficacy studies. Bacteriophage cocktails are increasingly proposed as alternatives to antibiotics against multidrug-resistant bacteria, yet their development remains largely empirical. This study challenges the assumption that the combination of effective phages yields additive or synergistic benefits. Through systematic evaluation of all possible three-phage combinations from five phages, we discovered that antagonistic interactions (50%) predominated over synergistic effects (10%), with some cocktails performing worse than individual phages. Using the Highest Single Agent independence model, we established a quantitative framework for rational cocktail design that identified a therapeutically superior formulation. This approach is generalizable across bacterial pathogens and provides a critical validation step for phage therapy development. Our findings demonstrate that rational testing of phage interactions is essential before in vivo or clinical translation, potentially preventing costly failures and accelerating the development of effective phage-based therapeutics against multidrug-resistant infections.\n\nID: 42294707\nTitle: From screening to treatment: in vitro and in vivo efficacy of phage-meropenem combination against highly virulent Carbapenem-resistant Acinetobacter baumannii.\nAbstract: Carbapenem-resistant Acinetobacter baumannii (CRAB) is a hospital-acquired pathogen of significant clinical importance. Given the slow progress in antibiotic development, phages have emerged as a novel therapeutic strategy against CRAB infections due to their synergistic effects with antibiotics. This study aims to explore phage-antibiotic combination therapy targeting CRAB, thereby providing a theoretical foundation for its clinical translation. Through virulence assessments in Galleria mellonella larvae and mice, CRAB110 was identified as the most virulent strain among 199 clinical CRAB isolates. Transcription analysis revealed that its enhanced pathogenicity may be associated with dysregulated pro-inflammatory responses. Using CRAB110 as the host bacterium, the newly isolated phage, P2, was selected for further study due to its high lytic efficiency and broad host range. The CRAB110 mutant strain CRAB110-2N, treated with P2, exhibited increased drug susceptibility and attenuated virulence compared to the wild-type strain. Both in vitro and in vivo experiments demonstrated that the combination of P2 with antibiotics achieved superior bacterial clearance compared to phage therapy alone. Furthermore, whole-genome analysis of CRAB110-2N revealed a mutation in its ugd. The constructed CRAB110\u0394ugd showed tolerance to P2; the quorum-sensing gene abaI was associated with phage susceptibility, with the CRAB110\u0394abaI strain displaying insensitivity to P2. These findings provide experimental evidence supporting the clinical application of phage-antibiotic combination therapy. This study focused on phage-antibiotic combination therapy targeting carbapenem-resistant Acinetobacter baumannii (CRAB), a priority pathogen designated by the World Health Organization (WHO). A highly virulent strain, CRAB110, was screened from 199 clinical isolates, and a novel, highly lytic phage, P2, was isolated from sewage samples. CRAB110-2N, a mutant strain induced by P2 exposure, displayed increased antibiotic susceptibility and attenuated virulence. Key findings showed that the combination of P2 and meropenem achieved a 99% bacterial clearance rate in vitro and exerted significant synergistic effects in vivo. Genomic analysis identified mutations in the ugd gene, and knockout experiments confirmed its correlation with phage susceptibility. Additionally, the quorum-sensing gene abaI was found to be associated with phage susceptibility in CRAB. Collectively, these results provide critical experimental evidence for the clinical translation of this phage-antibiotic combination therapy.\n\nID: 42284985\nTitle: Isolation and characterization of a lytic phage targeting carbapenem-resistant Pseudomonas aeruginosa.\nAbstract: Carbapenem-resistant Pseudomonas aeruginosa (CRPA) is a major clinical challenge because of the limited availability of effective treatment options. In this study, we isolated four phages, designated Zpj1-Zpj4, from hospital sewage samples using the clinical strain CRPA-11d as the host. Genomic analysis showed that these phages were closely related double-stranded DNA phages and lacked identifiable genes associated with lysogeny, virulence, or antibiotic resistance. Taxonomic analysis assigned them to the genus Yuavirus, subfamily Rabinowitzvirinae, family Mesyanzhinovviridae, and class Caudoviricetes. Among them, phage Zpj4 was selected for further characterization. Its biological properties were evaluated by determining genomic features, optimal multiplicity of infection (MOI), one-step growth kinetics, host range, efficiency of plating (EOP), stability, and in vitro antibacterial and anti-biofilm activities. Its therapeutic efficacy was further assessed in a CRPA-11d induced mouse model of acute lung injury by measuring bacterial burdens in the lungs, livers, and spleens, together with lung histopathology. Phage Zpj4 exhibited favorable properties, including a short latent period, a high burst size, and strong stability. It markedly inhibited CRPA-11d growth and biofilm formation in vitro. In the mouse model, phage Zpj4 treatment significantly reduced bacterial burdens in the lungs, livers, and spleens and alleviated lung tissue injury. These findings indicated that phage Zpj4 is a promising candidate for the treatment of CRPA infections.\n\nID: 42237556\nTitle: Ultra-Stable 2D Magneto-Fluorescent Probe-Mediated Multiplex Immunochromatographic Assay for Precise Bedside Detection of Sepsis.\nAbstract: Accurate bedside diagnosis of sepsis is essential for timely treatment and reducing mortality, yet technical limitations persist. Here, we present a multiplex-compatible lateral flow immunoassay (LFIA) that integrates a universal click-chemistry conjugation strategy with highly dispersible, film-like magnetic fluorescent probes (GFDQD@Si) to enable precise diagnosis through concurrent monitoring of pathogens and protein biomarkers. GFDQD@Si combines a two-dimensional high-area reactive interface; a magnetic interlayer for target enrichment and signal amplification; a multilayer of quantum dots for fluorescence enhancement; and an outer silica shell that suppresses background fluorescence and confers superior flowability. This architecture overcomes the size disparity between bacteria and proteins, enabling efficient cocapture of multiple proteins/bacteria and achieving faster, more sensitive detection on an LFIA platform. The platform quantitatively detects two key sepsis biomarkers\u2500procalcitonin (PCT) and interleukin-6 (IL6)\u2500as well as the pathogen Pseudomonas aeruginosa, with limits of detection of 4.44 pg mL-1 for PCT, 0.94 pg mL-1 for IL6, and 7 CFU mL-1 for bacteria. Validation in 75 clinical whole-blood samples demonstrated high sensitivity, ease of operation, and robustness, underscoring its potential for real-time bedside sepsis diagnosis. By simultaneously providing dual readouts of host-response biomarkers and pathogen detection, the GFDQD@Si-LFIA platform is expected to accelerate and improve clinical decision-making for sepsis.\n\nID: 42235888\nTitle: Human bacteraemia caused by Pseudomonas plecoglossicida, a fish pathogen of ayu (Plecoglossus altivelis): a case report.\nAbstract: Pseudomonas plecoglossicida is a gram-negative bacterium that primarily infects fish and is the causative agent of bacterial haemorrhagic ascites in ayu (Plecoglossus altivelis). Although sporadic human infections such as pneumonia and meningitis have been reported in recent years, human bacteraemia caused by P. plecoglossicida has not yet been documented. Here, we report the first known case of P. plecoglossicida bacteraemia in an 89-year-old male with a history of gastrectomy and recurrent adhesive intestinal obstruction. Following treatment for intestinal obstruction and aspiration pneumonia, including a 7-day course of cefmetazole, the patient developed fever and chills. Blood cultures yielded P. plecoglossicida, which was identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), whereas urine and sputum cultures yielded Escherichia coli and methicillin-resistant Staphylococcus aureus, respectively. Antimicrobial therapy was escalated to meropenem and subsequently de-escalated to ceftazidime based on susceptibility testing, resulting in prompt clinical improvement and complete resolution of the infection. Although the relevance of bacterial replacement phenomena observed in ayu aquaculture to human infection remains speculative, bacteraemia in this case was presumed to result from bacterial translocation associated with intestinal obstruction and disruption of the intestinal microbiota following recent antibiotic exposure. This case suggests that P. plecoglossicida may act as an opportunistic pathogen in patients with disrupted gut microbiota or anatomical vulnerabilities.\n\nID: 42210498\nTitle: Pyoverdine Plays Only a Minor, Strain-Specific Role in the Inhibition of Phytophthora infestans by Pseudomonas Strains.\nAbstract: The oomycete Phytophthora infestans is a detrimental pathogen currently controlled by massive applications of synthetic pesticides. In view of the pesticides' toxicity, biological control represents an attractive alternative to fight this pathogen. Pseudomonas strains are known to produce diverse specialized metabolites conferring protection against several crop diseases. Next to molecules causing direct pathogen inhibition, such as antibiotics and toxins, siderophores are considered important mediators of competitive inhibition of pathogens by Pseudomonas. However, whether siderophore production plays any role in the biocontrol of P. infestans has not yet been investigated. In this study, we focused on two Pseudomonas strains, Pseudomonas donghuensis R32 and Pseudomonas chlororaphis R47, both producing the siderophore pyoverdine, and previously characterized as inhibitors of P. infestans. The aim of this study was to evaluate the role of pyoverdine in the inhibition of P. infestans by both strains. For this purpose, we created pyoverdine-deficient mutants by knocking-out pvdE, the periplasmic ferribactin exporter, in both wild-types and HCN-deletion mutants. These mutants were then tested for activity against P. infestans in different in vitro assays as well as in leaf discs. Our results indicate that pyoverdine plays no role in the inhibition of P. infestans by P. donghuensis R32 and only a minor role in P. chlororaphis R47, which was observed solely in leaf disc assays. Nevertheless, our findings demonstrate that iron competition plays an important role in the antagonistic effect of P. donghuensis R32 on P. infestans and suggest the involvement of another siderophore in the competition for iron.\n\nID: 42210480\nTitle: [Screening, identification, and growth-promoting effects of cold-tolerant phosphate-solubilizing bacteria from high-altitude cold engineering area].\nAbstract: Ecological restoration of degraded alpine engineering areas faced severe challenges due to soil phospho-rus deficiency and low-temperature. Chemical phosphorus fertilizers had low efficiency and easily caused environmental risks, while conventional phosphate-solubilizing bacteria showed lower activity at low temperatures. Therefore, screening microbial resources with both cold tolerance and high-efficiency phosphate-solubilizing and growth-promoting functions was crucial for achieving green ecological restoration in alpine regions. In this study, we isolated and screened cold-tolerant phosphate-solubilizing bacteria from soils of disturbed engineering areas on the Wes-tern Sichuan Plateau. We evaluated their phosphate-solubilizing capacity and abilities to secrete organic acids, si-derophores, and indole-3-acetic acid (IAA) across a temperature gradient (6, 10, and 28 \u2103), and verified their growth-promoting effects in a pot experiment. We obtained three highly efficient cold-tolerant phosphate-solubilizing strains (P-6, P-18, and P-25), which were identified as members of Pseudomonas genus. These strains maintained good phosphate-solubilizing capacity within the range of 6-28 \u2103, among which strain P-25 exhibited the highest phosphorus solubilization (481.26 mg\u00b7L-1) at 10 \u2103. Mechanistic analysis revealed that the three strains activated inorganic phosphorus mainly by secreting organic acids and siderophores, and strains P-18 and P-25 could synthesize IAA. Inoculation with these strains significantly increased soil available phosphorus content and promoted the growth of Elymus nutans. The P-25 treatment performed the best, with plant phosphorus content, biomass, and plant height being increased by 109.2%, 65.2%, and 6.7%, respectively. All the three cold-tolerant phosphate-solubilizing bacteria strains possessed both high-efficiency phosphate-solubilizing and growth-promoting functions, and thus had application potential in the ecological restoration of alpine engineering sites. \u9ad8\u5bd2\u5de5\u7a0b\u53d7\u635f\u533a\u751f\u6001\u6062\u590d\u56e0\u571f\u58e4\u78f7\u7d20\u532e\u4e4f\u4e0e\u4f4e\u6e29\u73af\u5883\u800c\u9762\u4e34\u4e25\u5cfb\u6311\u6218\u3002\u5316\u5b66\u78f7\u80a5\u6548\u7387\u4f4e\u4e0b\u4e14\u6613\u9020\u6210\u73af\u5883\u98ce\u9669,\u800c\u5e38\u89c4\u6eb6\u78f7\u83cc\u5728\u4f4e\u6e29\u4e0b\u6d3b\u6027\u53d7\u9650\u3002\u56e0\u6b64,\u7b5b\u9009\u517c\u5177\u8010\u5bd2\u7279\u6027\u4e0e\u9ad8\u6548\u6eb6\u78f7\u4fc3\u751f\u529f\u80fd\u7684\u5fae\u751f\u7269\u8d44\u6e90,\u5bf9\u4e8e\u5b9e\u73b0\u9ad8\u5bd2\u5730\u533a\u7684\u7eff\u8272\u751f\u6001\u4fee\u590d\u81f3\u5173\u91cd\u8981\u3002\u672c\u7814\u7a76\u4ece\u5ddd\u897f\u9ad8\u539f\u5de5\u7a0b\u6270\u52a8\u533a\u571f\u58e4\u4e2d\u5206\u79bb\u7b5b\u9009\u8010\u5bd2\u6eb6\u78f7\u83cc,\u901a\u8fc7\u591a\u6e29\u5ea6\u68af\u5ea6(6\u300110\u300128 \u2103)\u8bc4\u4f30\u5176\u6eb6\u78f7\u80fd\u529b\u4ee5\u53ca\u5206\u6ccc\u6709\u673a\u9178\u3001\u94c1\u8f7d\u4f53\u548c\u5432\u54da\u4e59\u9178(IAA)\u7684\u80fd\u529b,\u5e76\u901a\u8fc7\u76c6\u683d\u8bd5\u9a8c\u9a8c\u8bc1\u5176\u4fc3\u751f\u6548\u5e94\u3002\u5171\u83b7\u5f973\u682a\u9ad8\u6548\u8010\u5bd2\u6eb6\u78f7\u83cc(P-6\u3001P-18\u4e0eP-25),\u9274\u5b9a\u4e3a\u5047\u5355\u80de\u83cc\u5c5e\u3002\u5b83\u4eec\u57286~28 \u2103\u8303\u56f4\u5185\u5747\u4fdd\u6301\u826f\u597d\u7684\u6eb6\u78f7\u80fd\u529b,\u5176\u4e2dP-25\u572810 \u2103\u65f6\u6eb6\u78f7\u91cf\u6700\u9ad8(481.26 mg\u00b7L-1)\u3002\u673a\u7406\u5206\u6790\u63ed\u793a,3\u682a\u83cc\u682a\u4e3b\u8981\u901a\u8fc7\u5206\u6ccc\u6709\u673a\u9178\u4e0e\u94c1\u8f7d\u4f53\u6d3b\u5316\u65e0\u673a\u78f7,P-18\u4e0eP-25\u8fd8\u80fd\u5408\u6210IAA\u3002\u76c6\u683d\u8bd5\u9a8c\u8868\u660e,\u63a5\u79cd\u83cc\u682a\u53ef\u663e\u8457\u63d0\u9ad8\u571f\u58e4\u6709\u6548\u78f7\u542b\u91cf,\u4fc3\u8fdb\u5782\u7a57\u62ab\u78b1\u8349\u751f\u957f,\u5176\u4e2dP-25\u5904\u7406\u6548\u679c\u6700\u4f73,\u690d\u682a\u78f7\u542b\u91cf\u3001\u751f\u7269\u91cf\u53ca\u682a\u9ad8\u5206\u522b\u8f83\u5bf9\u7167\u63d0\u5347109.2%\u300165.2%\u548c6.7%\u30023\u682a\u8010\u5bd2\u6eb6\u78f7\u83cc\u517c\u5177\u9ad8\u6548\u6eb6\u78f7\u4e0e\u4fc3\u751f\u529f\u80fd,\u5728\u9ad8\u5bd2\u5de5\u7a0b\u8ff9\u5730\u751f\u6001\u4fee\u590d\u4e2d\u5177\u6709\u5e94\u7528\u6f5c\u529b\u3002.\n\nID: 42206754\nTitle: Isolation of a Novel Lytic Pseudomonas aeruginosa Phage Henu5 and Fitness Costs of Phage-Driven Resistance.\nAbstract: Phage therapy is increasingly recognised as a potential approach against antibiotic-resistant infections. Analogous to the rise of antibiotic resistance, bacteria can also evolve phage resistance, a process that frequently entails fitness costs. In this study, a new lytic Pseudomonas aeruginosa phage (Henu5) was isolated and characterised. Henu5 was classified within the Caudoviricetes class and displayed good biological characteristics. The Henu5 genome possesses 92,558\u2009bp of linear dsDNA and a GC content of 49.36%. Additionally, three phage-resistant mutants, R3, R6 and R14, were isolated and investigated for adaptive trade-offs. Compared to wild-type, the phage-resistant mutants mostly exhibited fitness costs in growth, altered morphology, impaired adsorption, reduced biofilm and pyocyanin production and impaired motility, which was confirmed by transmission electron microscopy, as well as increased susceptibility to various antibiotics. In\u00a0vivo experiments revealed improved survival, alongside diminished colonisation and pathogenicity. Comparative genomics identified mutations in the genes pilQ (R3 and R14) and pilR (R6), both crucial for type IV pili (T4P) biosynthesis and potentially conferring phage resistance, with additional mutations related to the obtained trade-offs. Transcriptomic and real-time quantitative PCR proved that T4P-related genes, together with the hmgA, galU, wzy, fliG, pslA, mexH and exoY genes, were downregulated in all resistant mutants, while the qscR and mvaT genes were upregulated. Collectively, while phage resistance evolution remains an issue, this study suggests that the fitness costs of the phage-resistant mutants might be invaluable for effective phage therapies.\n\nID: 42178710\nTitle: Whole-genome sequencing uncovers the extreme adaptation mechanisms of Pseudomonas sp. Ma2-10 screened from the Antarctic sea sediment near King George Island.\nAbstract: Pseudomonas sp. Ma2-10 was isolated from marine sediment near King George Island, South Shetland Islands, Antarctica. In this study, we determined the complete genome sequence of this strain. The results showed that the strain has a genome size of 5,811,804\u00a0bp with a GC content of 58.5\u00a0mol%, and the coding region accounted for 89.03% of the total genome length, containing 5095 protein-coding genes. Through annotation with the CAZy database, we identified 120 carbohydrate-active enzymes, indicating that Ma2-10 has an extremely strong ability to synthesize extracellular polysaccharides (EPS). Functional annotation of the strain's genome using KEGG and GO databases revealed that the strain's genes were significantly enriched in amino acid metabolism, carbohydrate metabolism, membrane transport, and signal transduction pathways, providing a molecular basis for its adaptation to the extreme environments of low temperature, high salt, and oligotrophy. Nine secondary metabolite biosynthetic gene clusters were identified through secondary metabolite synthesis analysis. These gene clusters indicate that the strain has the potential to produce various bioactive substances such as antibiotics and siderophores, which can be used for niche competition and stress resistance, and possesses a genetic basis for antioxidant activity and hyperosmotic tolerance. The results of this study can provide a reference for further understanding and exploitation of the beneficial functions of Pseudomonas sp. Ma2-10.\n\nID: 42165624\nTitle: Characterization and comparative genomic analysis of a novel bacteriophage against an extremely drug-resistant Pseudomonas aeruginosa ST1971.\nAbstract: Given the rising prevalence of multidrug-resistant strains, Pseudomonas aeruginosa necessitates alternative therapies, and phages are emerging as promising antibiotic alternatives. Our study introduces a novel lytic phage, CRPAP1904, exhibiting potent activity against an extremely drug-resistant P. aeruginosa ST1971 strain CRPA190. Phylogenetic and comparative genomic analyses validated the novelty of phage CRPAP1904, suggesting that it represents a new species of the Kochitakasuvirus genus. The phage CRPAP1904 has a double-stranded DNA genome of 62,430 bp base pairs, a GC content of 60.4% and predicted 83 open reading frames. Notably, no genes associated with virulence or antibiotic resistance were detected, suggesting its suitability for therapeutic applications. We further assessed the phage's host range, optimal multiplicity of infection (MOI), one-step growth curves, physicochemical stability, and antibacterial activity, which are critical for its application in environmental and clinical settings. The phage exhibits a broad host range, lysing 83% (20/24) of tested strains. The optimal MOI was 0.01 with a large burst size of 109 PFU/cell. Additionally, the phage exhibited stability over a pH range of 6-8 and at temperatures ranging from -20\u00b0C to 60\u00b0C. In vitro, the phage significantly suppresses host bacterial growth at an MOI of 100 for the first 12 h, although resistant mutants gradually emerge during prolonged exposure. In conclusion, the newly discovered phage CRPAP1904 expands phage resources and supports medicinal phage library development, advancing phage therapy and biocontrol applications in MDR-PA infections. This study isolated a novel phage, CRPAP1904, from the hospital's sewage that specifically targets an extremely drug-resistant Pseudomonas aeruginosa ST1971 strain CRPA190. Genomic analysis identified CRPAP1904 as a new Kochitakasuvirus member lacking antibiotic resistance genes and virulence factors. CRPAP1904 shows excellent stability and lytic activity against MDR-PA clinical isolates. As the first phage against Pseudomonas aeruginosa ST1971, this work expands phage resources and supports medicinal phage library development, advancing phage therapy and biocontrol applications in MDR-PA infections.\n\nID: 42160310\nTitle: The Pseudomonas aeruginosa ribonuclease Ribocin cleaves eukaryotic ribosomes at helix 69 to inhibit host translation.\nAbstract: Pseudomonas aeruginosa employs host translation inhibition as a virulence-enhancing strategy. We previously showed that the bacterium induces cleavage of Caenorhabditis elegans large ribosomal RNA at helix 69 (H69), part of a central intersubunit bridge and the ribosomal decoding center. In this study, we demonstrate that a previously uncharacterized ribonuclease, Ribocin, is necessary and sufficient for H69 cleavage. Recombinant Ribocin cuts H69 in worm and mammalian ribosomes, indicating that H69 cleavage by P. aeruginosa is phylogenetically conserved. In worms, mammalian cells, and rabbit reticulocyte lysates, H69 cleavage results in translation inhibition. Furthermore, Ribocin contributes to bacterial virulence toward C. elegans, triggers a major host response to translation inhibition, and operates in parallel with Exotoxin A-mediated translation inhibition. These findings unveil the first known nuclease that cleaves eukaryotic ribosomes at H69 and expand the understanding of host translation-inhibition by establishing targeted rRNA cleavage as a mechanism of host attack.\n\nID: 42156951\nTitle: Characterization and evaluation of the efficacy of phage E21 therapy in a wound animal model of biofilm-associated Pseudomonas aeruginosa infection.\nAbstract: Skin infections caused by strong biofilm Pseudomonas aeruginosa (P. aeruginosa) are considered a serious public health issue because of the increased resistance toward the currently available antibiotics. Consequently, innovative therapeutic strategies have emerged to address these challenging infections. Among them, phage therapy stands out, in which highly potent lytic bacteriophages (phages) are specifically selected to target and eradicate the responsible pathogens. In this study, Pseudomonas phage E21 was recovered from sewage, and it genetically belongs to the Lavrentievirus genus, Casjensviridae family. The genetic characterization of the isolated phage reveals the presence of highly potent lytic enzymes, which play a critical role in effectively suppressing the growth of the targeted pathogens. The phage has high stability patterns over a wide range of temperatures and pH values (65 \u2103 and 3-11). Carboxymethylcellulose was used to formulate a hydrogel for the evaluation of the bacteriophage's efficacy against biofilm-associated wound infection in a suitable animal model. The result of the preclinical study confirmed the efficacy of isolated phage in the therapy of biofilm-associated wound infection.\n\nID: 42150716\nTitle: Novel dual-targeting biofilm inhibitors for potentiating antibiotic efficacy against multidrug-resistant Pseudomonas aeruginosa infections.\nAbstract: With the increasing global challenge posed by multidrug-resistant Pseudomonas aeruginosa, which utilizes biofilm formation and virulence mechanisms to exacerbate infections, there is an urgent need for novel therapeutic strategies. This work presents a novel dual-targeting biofilm inhibitor that potentiates antibiotic efficacy, offering a potent and safe candidate to combat P. aeruginosa infections. To address this problem, we developed dual-targeting biofilm inhibitors that simultaneously disrupt the quorum sensing (QS) system and iron homeostasis system via computer-aided drug design. Through integrated in vitro screening and computational ADMET profiling, HK-34b, a 1-hydroxybenzimidazolone derivative, was identified. HK-34b inhibited 89% biofilm formation (IC 50\u00a0=\u00a00.15 \u03bcg/mL) and eradicated 93% mature biofilms. It also reduced virulence factor production in P. aeruginosa, thereby impairing swarming motility. Notably, HK-34b combined with tobramycin and ciprofloxacin achieved 99% bacterial clearance, enhancing antibiotic efficacy by 400-fold and 2000-fold in murine wound models, respectively. Furthermore, HK-34b exhibited low toxicity in vivo. Pharmacokinetic studies demonstrated that HK-34b possesses favorable bioavailability (36.86%) and a wide safety window. Mechanistic studies confirmed the dual targeting mechanism of HK-34b, which inhibits the pqs system of P. aeruginosa by binding to PqsR (KD PqsR\u00a0=\u00a03.23\u00a0\u03bcM), a key virulence regulator of the QS system, and disrupts bacterial iron homeostasis through interaction with FpvA (KD FpvA\u00a0=\u00a05.56\u00a0\u03bcM), the outer membrane receptor for siderophores. MD simulations revealed stable binding of HK-34b to both PqsR and FpvA. This dual-targeting strategy demonstrates significant translational potential by employing a novel chemical scaffold, which not only avoids the cross-resistance risks associated with the shared molecular scaffolds of conventional siderophore-antibiotic conjugates, but also overcomes the drawbacks of insufficient biofilm efficacy seen with single-target inhibitors, thereby providing a sustainable approach for the treatment of multidrug-resistant P. aeruginosa infections.\n\nID: 42401803\nTitle: A genome-wide association study to identify the genetic loci underlying carbapenem resistance in Acinetobacter baumannii.\nAbstract: Carbapenem-resistant Acinetobacter baumannii (CRAB) presents a significant public health concern, and is recognized as a key contributor to the global antimicrobial resistance (AMR) crisis. This study applied a bacterial genome-wide association study (bGWAS) framework to identify genetic factors beyond the canonical carbapenemase OXA-23, that may contribute to carbapenem resistance. A. baumannii isolates with publicly available whole-genome sequencing (WGS) data and carbapenem-specific antimicrobial susceptibility testing (AST) results were compiled (n\u2009=\u20091,601). Unitigs were extracted from de novo assemblies, and single-nucleotide polymorphisms (SNPs) were called from raw sequence reads mapped to seven selected reference genomes. The unitig- and SNP-based genome-wide association analyses were carried out, including conditional analyses based on the known resistance determinants. Structural analysis was performed for the select candidate mutations. The population was highly clonal and comprised ten lineages, including three predominantly resistant lineages (ST1, ST2, and ST32). Known CRAB-associated loci, including OXA-23, the RND efflux pump regulator AdeL, and OXA-66 variants (Ile129Leu and Leu167Val), were readily identified. Structural analysis of mutations identified outer-membrane proteins as potential candidate loci, however these loci were not supported in the conditional analyses across all reference genomes. The candidate loci supported in the conditional analysis across reference genomes included an amino acid substitution in a LysR-type regulator adjacent to the biofilm-associated operon pgaABCD, and an intergenic substitution located between enzymes involved in LPS remodeling. OXA-23 is the major determinant of carbapenem resistance in A. baumannii. Additional resistance mechanisms may become significant in the absence of OXA-23, including efflux pump regulation (AdeL), membrane permeability (OprD, DcaP), lipopolysaccharide (LPS) transport (PqiB), LPS remodeling (acyltransferase, glycosyltransferase), and biofilm formation (LysR). Integration of the conditional analysis based on known resistance determinants and a multi-reference mapping framework may improve the detection and prioritization of candidate associations.\n\nID: 42401059\nTitle: The overlooked risk of horizontal transfer of plasmid-borne antibiotic resistance genes induced by organophosphate esters in aquaculture environments.\nAbstract: In recent years, the emergence of new environmental pollutants has drawn increasing attention to the plasmid-mediated conjugation transfer of antibiotic resistance genes (ARGs) induced by these contaminants. The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized.\n\nID: 42391897\nTitle: Bacteriostatic mechanisms of CO2 against high-oxygen packaged meat-borne Pseudomonas fragi during chilled storage: Membrane physiological and microstructural changes.\nAbstract: The CO2 inside high-oxygen modified atmosphere packaging (HiOx-MAP) greatly retards the predominant Pseudomonas fragi (P. fragi) growth in chilled meat, whereas the CO2-regulated mechanism on P. fragi cell membrane properties is still unclear. This study investigated the influences of CO2 on both type and wild-type P. fragi growth and cell membrane characteristics during the chilled storage of HiOx-MAP (TMAP\u00a0=\u00a050% O2/40% CO2/10% N2; CMAP\u00a0=\u00a050% O2/50% N2). Compared to CMAP, TMAP significantly reduced P. fragi counts by limiting its motility and disturbing cell membrane structure, composition and function, without causing membrane rupture. CO2 weakened P. fragi membrane function by inducing phospholipid perturbations, but promoted intracellular adenosine triphosphate production as a stress response. Although both packaged P. fragi membrane fluidity and permeability first decreased then increased during storage, a higher (P\u00a0<\u00a00.05) membrane fluidity and permeability was observed in TMAP P. fragi than in CMAP P. fragi over time, indicating P. fragi gradually adapted to a high-CO2 environment. The CO2-elevated ratio of unsaturated to saturated fatty acids significantly increased P. fragi membrane fluidity, and thus enhanced its membrane permeability. This study offers a new mechanistic basis for the CO2-bacteriostatic action in meat preservation targeted at bacterial cell membranes.\n\nID: 42369557\nTitle: Structural determinants of the scorpion venom peptide Uy234 govern bactericidal activity and membrane-disruptive properties.\nAbstract: The growth-inhibiting effect of the peptide Uy234, present in the venom of the scorpion Urodacus yaschenkoi, has been investigated in two bacterial pathogens: Staphylococcus aureus ATCC 25923 and Acinetobacter baumannii AE12, the latter being a multidrug-resistant clinical isolate. With the aim of determining the possible role of specific residues in the bioactivity of this peptide, we studied a proline residue at position 9 and the C-terminal amidation of this peptide. Two inactivated variants were analyzed: Uy234-C, a non-amidated peptide, and Uy234-A, a P9A mutant. In addition to quantifying in detail the minimum inhibitory and bactericidal concentrations for each microorganism, membrane-damaging effects were assessed through bacterial cell viability assays with SYTO9/PI fluorophores. In addition, AFM, electroforming, and GUV microaspiration were used to determine the effects of each peptide in terms of permeabilization. Molecular dynamics (MD) simulations were also performed for the wild-type peptide and its P9A mutant. Only the native peptide Uy234 showed bacteriostatic and bactericidal activity, whereas the P9A mutant and non-amidated variant lost antimicrobial activity, demonstrating the essential role of the Pro-9 residue and C-terminal amidation in Uy234 bioactivity against both pathogens. SYTO9/PI assays in S. aureus infection showed membrane damage only with native Uy234, while AFM and GUV studies revealed membrane thinning, lateral expansion, and dose-dependent permeabilization of lipid bilayers. Our study provides clear evidence of a damaging effect on the membrane associated with the bioactivity of Uy234. This bioactivity is directly associated with the presence of residue P9 and the presence of C-terminal carboxyamidation. The mutant peptide P9A is unable to permeabilize GUVs, which is consistent with the persistence of a greater degree of structural order, according to MD simulations in the aqueous phase. This study provides a framework for the rational design of bactericidal peptides targeting multidrug-resistant bacteria.\n\nID: 42347254\nTitle: The Rise in Carbapenem-Resistant Acinetobacter baumannii and the Emergence of Eravacycline as a Treatment Strategy: A Narrative Review.\nAbstract: Acinetobacter baumannii is a significant pathogen of hospital-acquired infections, and its multidrug resistance (MDR) and extended drug resistance (XDR) have become increasingly severe, posing a global public health challenge. This article provides a narrative review of the major resistance mechanisms of Acinetobacter baumannii, including \u03b2-lactamase production, efflux pump overexpression, target site modification, reduced membrane permeability, and biofilm formation. Additionally, it summarizes the current main drugs and their target sites for treating MDR Acinetobacter baumannii infections, with a focus on the mechanism of action, antibacterial activity, and clinical research progress of the novel fully synthetic fluorocycline antibiotic-eravacycline. Eravacycline inhibits protein synthesis by high-affinity binding to the bacterial ribosomal 30S subunit and demonstrates activity against multidrug-resistant Acinetobacter baumannii (excluding Pseudomonas aeruginosa), providing a potential novel therapeutic option for MDR/XDR Acinetobacter baumannii infections. Finally, the article outlines future research directions and treatment strategies. Due to the narrative nature of this review, no systematic methodology (e.g., PRISMA) was applied, and the available clinical evidence, particularly for CRAB infections, remains limited.\n\nID: 42341627\nTitle: The synthesis of 6'-N-acyl neamine-based amphiphiles: Synergistic activity against Pseudomonas aeruginosa via enhanced membrane permeability.\nAbstract: Amphiphilic aminoglycosides offer a promising approach to combat antibiotic resistant Gram-negative bacteria. Here, a series of neamine-based amphiphiles bearing alkyl chains of varying lengths (C4-C16) was synthesized via a concise route through selective modification at the 6'-amino position of neamine. Antibacterial evaluation revealed a chain length-dependent activity, with the C14- and C15-alkyl neamine amphiphiles exhibiting the most potent antibacterial activity against ESKAPE pathogens. The C15 derivative displayed superior activity compared to neamine and synergized with multiple clinical antibiotics against P. aeruginosa. Mechanistic studies indicated that this synergy results from enhanced outer membrane permeability, and cytotoxicity assays confirmed low toxicity at therapeutically relevant concentrations.\n\nID: 42338148\nTitle: Adaptive Laboratory Evolution Unlocks Membrane Permeability as a Key Limitation in Long-Chain Alcohol Metabolism by Pseudomonas putida KT2440.\nAbstract: Pseudomonas putida KT2440, renowned for its diverse metabolic capabilities, is a promising platform for downstream processing and revalorisation of recalcitrant molecules. In this study, we examined and optimised P. putida KT2440's ability to utilise products of the degradation of polyethylene (PE), the most used and disposed plastic. PE degradation creates over 200 molecules that vary in oxidation level and, thus, chemical properties. Among those, long-chain alcohols represent one of the most challenging fractions to process due to their poor solubility. Using them as feedstock for microbial growth would close the plastic-derived carbon cycle, reducing environmental impact. First, we discovered that P. putida KT2440 can use the long-chain alcohols, 1-hexadecanol and 1-eicosanol, as the sole carbon and energy source. Using adaptive laboratory evolution (ALE), we generated variants with improved growth rates on such substrates. Mutations that became fixed during ALE provided insights into the mechanism, highlighting the importance of cell-substrate interaction. By heterologously expressing a hydrocarbon transporter-encoding gene, we successfully reproduced the ALE-derived phenotype, suggesting that the bottleneck in long-chain alcohol utilisation lies in uptake rather than substrate transformation. These findings lay the groundwork for the potential application of P. putida KT2440 for the valorisation of PE degradation products.\n\nID: 42321988\nTitle: Exploring the In Vitro Antibacterial Properties of Milicia regia and Entandrophragma angolensis: Insight Into Their Antibiofilm and Efflux Pump Inhibitory Activities.\nAbstract: Biofilms are breeding grounds for adapted and acquired antibiotic resistance through increased efflux activities and horizontal gene transfer. Medicinal plants are sources of antimicrobial agents for the treatment of bacterial, parasitic, and fungal infections. In this research, we examined antimicrobial, antibiofilm, and efflux pump inhibition activity of the methanolic extracts of the stem barks of Milicia regia and Entandrophragma angolensis. Crude methanolic extracts were assessed using three distinct assays: the high-throughput spot culture growth inhibition (HT-SPOTi) assay for bacterial growth inhibition, a crystal violet-based antibiofilm screening assay to quantify their biofilm\u2011inhibitory activity and the ethidium bromide accumulation assay for evaluating changes in bacterial cell membrane permeability against Mycobacterium smegmatis, Mycobacterium aurum, Staphylococcus aureus, and Pseudomonas aeruginosa. The preliminary qualitative phytochemical screening suggested the presence of tannins, flavonoids, terpenoids, glycosides, alkaloids, and saponins. The minimum inhibitory concentrations for extracts against S. aureus, P. aeruginosa, M. aurum, and M. smegmatis were 250, 125, 500, and 250\u2009\u03bcg/mL, respectively, and for E. angolensis: 125, 125, 500, and 500\u2009\u03bcg/mL, respectively. Both plants displayed significant (\u2217\u2217\u2217\u03c1 < 0.005) biofilm inhibition activities against all bacteria with the highest inhibition recorded in S. aureus: M. regia, E. angolensis, and the reference drug ciprofloxacin were 73%, 62%, and 79%, respectively. The extracts produced marked antiefflux pump effects against S.aureus and P. aeruginosa. This study established the antibacterial, antibiofilm, and efflux pump inhibitory capacities of M. regia and E. angolensis and provides the rationale for their folkloric uses in the treatment of infections.\n\nID: 42266348\nTitle: Synthesis, characterisation and antibacterial activity of flavone-based Sn(iv) and Sb(iii) complexes.\nAbstract: Three 3-hydroxyflavone ligands (L1-L3) and their corresponding Sn(iv) and Sb(iii) complexes (1-6) of general formula [Sn(L)3]Cl (1-3) and [Sb(L)2Cl] (4-6), where L is the monoanionic form of 3-hydroxy flavone (L1 in 1 and 4), naphthyl flavone (L2 in 2 and 5) or anthracenyl flavone (L3 in 3 and 6), are synthesized and characterised using UV-visible, fluorescence, IR, NMR and high-resolution mass spectral studies. The compounds were evaluated against Staphylococcus aureus (MTCC 96), Escherichia coli (MTCC 111), Pseudomonas aeruginosa (MTCC 1688) and Klebsiella pneumoniae (MTCC 432). In general, coordination of the flavone ligands to Sn(iv) and Sb(iii) enhanced antibacterial activity relative to the parent ligands and the corresponding metal salts. Among the series, the Sb(iii) complexes were the most active, with complex 6 showing the highest potency, particularly against S. aureus, for which the minimum inhibitory concentration (MIC) was 2.9 \u00b5g mL-1, comparable to ciprofloxacin under the tested conditions. The expanded MIC dataset also indicated a clear organism-dependent susceptibility pattern, with S. aureus being more susceptible than the tested Gram-negative bacteria. Checkerboard analysis further revealed synergistic interactions between the Sb(iii) complexes and ciprofloxacin against S. aureus. Mechanistic studies, including scanning electron microscopy, membrane permeability analysis and propidium iodide staining, indicated that the antibacterial action of complex 6 involves disruption and permeabilization of the bacterial membrane. In addition, the cytotoxic effects of the two most active complexes, 5 and 6, were assessed in human dermal fibroblast (HDF) cells by MTT assay. Both complexes maintained high HDF viability at their respective MICs against S. aureus, indicating that their anti-staphylococcal activity was achieved at concentrations that did not cause marked cytotoxicity under the tested conditions. These findings identify Sb(iii)-bound flavonoid complexes as promising scaffolds for further antibacterial investigation.\n\nID: 42250397\nTitle: Synergistic antibacterial activity and multi-target mechanism of phage endolysin LysPFX32 combined with Cinnamaldehyde against Pseudomonas fluorescens in protein-rich food matrices.\nAbstract: To overcome the outer membrane barrier that restricts endolysin efficacy against Gram-negative bacteria such as Pseudomonas fluorescens, the natural compound cinnamaldehyde could be employed as a membrane-permeabilizing agent to destabilize this protective layer. This study quantified the synergistic interaction between the novel endolysin LysPFX32 and cinnamaldehyde using the fractional inhibitory concentration index (FICI). The antibacterial mechanisms of endolysin and cinnamaldehyde were investigated by assessing outer and inner membrane integrity, observing morphological changes via scanning electron microscopy (SEM), monitoring membrane permeability using confocal laser scanning microscopy (CLSM), analyzing DNA-binding capacity, and profiling transcriptional responses through qPCR. The results demonstrated significant synergy, with a FICI of 0.425, which reduced the required concentration of LysPFX32 by 16-fold. The combined treatment compromised both the outer and inner membrane integrity, resulting in the leakage of intracellular nucleic acids (127.73\u00a0ng/\u03bcL) and proteins (87.45\u00a0mg/mL). Furthermore, the combined treatment demonstrated potent anti-biofilm activity, with a 56.07% inhibition rate against biofilm formation and a 66.7% removal rate for mature biofilms, while also downregulating key genes associated with quorum sensing, biofilm development, and motility (specifically pcoI, pcoR, and fliI). In food models, the synergistic treatment effectively suppressed the growth of P. fluorescens, which reduced total volatile basic nitrogen (TVB-N) production and extended the product shelf life by 4\u00a0days. This study proposes a novel and natural biological strategy, which is mechanistically complementary, for controlling spoilage bacteria. It offers a promising natural preservative solution for the food industry.\n\nID: 42219972\nTitle: Secondary metabolites in a mangrove-associated fungus Aspergillus fumigatus 06T03 and their antibacterial activity.\nAbstract: Eight compounds were isolated and identified from Aspergillus fumigatus 06T03, a rhizospheric soil fungus obtained from the soil of Aegiceras corniculatum. These include aspertriterpene A (AT-A,1), chaetominine (CHM,2), fumitremorgin B (FT-B,3), verruculogen (VRC,4), 12,13-dihydroxyfumitremorgin C (DH-FT-C,5), asperfumigatin (AFG,6), fumitremorgin C (FT-C,7), and verruculogen TR-2 (VRC-TR2,8). Their structures were elucidated through comprehensive spectroscopic analysis and single-crystal X-ray diffraction. Notably, AT-A(1) represents a new isolate from the genus Aspergillus sp., and its crystal structure is reported here for the first time. In vitro antibacterial assays revealed that AT-A(1) exhibited potent inhibitory activity against Pseudomonas aeruginosa and Staphylococcus aureus, with minimum inhibitory concentration (MIC) values of 2\u2009\u00b5g/mL and 4\u2009\u00b5g/mL, respectively. Further investigation demonstrated that AT-A(1) significantly suppresses bacterial biofilm formation. Moreover, when administered at a specific concentration, it can compromise the structural integrity of bacterial cell membranes and enhance membrane permeability. This study expands the chemical diversity of secondary metabolites from mangrove-derived A. fumigatus. Furthermore, this is the first report of compounds 2-8 as constituents of fungi associated with A. corniculatum, reinforcing the potential of mangrove-associated microorganisms as a prolific source of bioactive natural products.\n\nID: 42196587\nTitle: Synergy Between the Auranofin Analogue PEt3AuCl and Membrane Disruptors, Efflux-Pump Blockers, and Glutathione-Depletors Uncovers Tolerance Pathways in Pseudomonas aeruginosa.\nAbstract: Auranofin (AF), an FDA-approved drug for rheumatoid arthritis, exhibits strong antibacterial activity against Gram-positive bacteria, while Gram-negative species remain largely tolerant. This study assessed the antimicrobial activity of AF and three analogues against clinically relevant Gram-negative pathogens and explored tolerance mechanisms in Pseudomonas aeruginosa. Broth microdilution assays were performed on reference strains and clinical isolates of Escherichia coli, Klebsiella pneumoniae, and P. aeruginosa. Synergy studies with the most active analogue, PEt3AuCl (AF-Cl), were conducted against P. aeruginosa using polymyxin B (PMB), two efflux-pump inhibitors, and two glutathione (GSH) depletors. Gold compounds showed MICs between 4 and >64 \u00b5g/mL, with AF-Cl displaying the highest activity. AF-Cl activity was markedly enhanced by PMB and efflux-pump inhibitors, indicating that outer membrane permeability and efflux contribute to tolerance. Additionally, GSH depletion significantly potentiated AF-Cl, implicating redox homeostasis in resistance. Overall, AF-Cl shows potential against Gram-negative bacteria when combined with agents targeting membrane integrity, efflux systems, or redox balance, supporting combinatorial strategies to overcome resistance in P. aeruginosa and related pathogens.\n\nID: 42146247\nTitle: Novel Fluorinated Chlorhexidine Analogues Overcome Resistance in Gram-Negative Bacteria.\nAbstract: Antimicrobial resistance (AMR) is a critical global health challenge that compromises the effectiveness of widely used biocides such as chlorhexidine (CHX). The emergence of CHX-resistant bacterial strains, often mediated by efflux mechanisms and membrane adaptations, necessitates the development of new chemical entities capable of overcoming these resistance pathways. Here, we report the rational design, synthesis, and biological evaluation of structurally modified CHX analogues. These analogues were designed by substituting the terminal chlorophenyl rings of CHX with strategically selected aromatic groups bearing fluorine and methyl substituents to enhance membrane permeability, modulate physicochemical properties, and reduce efflux susceptibility. A library of 13 compounds was prepared using biscyanoguanidine chemistry and aniline-based substitutions via microwave-assisted synthesis, and was fully characterized by LC-MS, HRMS, and NMR. Antibacterial activity was assessed using minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) assays against a panel of Gram-positive and Gram-negative bacteria, including CHX-resistant Klebsiella pneumoniae and Pseudomonas aeruginosa strains harboring smvR, phoQ, and pmrB mutations. Selected analogues, particularly compounds 8 and 11, demonstrated potent antibacterial activity. Compound 11 showed MIC values predominantly in the range of 4-8 \u03bcg/mL across wild-type strains and retained activity in resistant isolates, with MIC values of 4-8 \u03bcg/mL in P. aeruginosa and 64 \u03bcg/mL in CHX-resistant K. pneumoniae. MBC values were generally comparable to MIC values for the fluorinated analogues, consistent with a biocidal mode of action, while chlorhexidine showed elevated MBC values in resistant strains. Molecular modeling suggests that these compounds form favorable interactions within hydrophobic regions of the SmvA efflux pump in K. pneumoniae, potentially reducing efflux susceptibility. Structure-activity relationship analysis highlights the importance of combining fluorine and methyl substituents to optimize physicochemical properties associated with antibacterial activity and resistance bypass. Collectively, these findings establish a foundation for the development of next-generation CHX-based biocides with improved efficacy against multidrug-resistant pathogens and support further translational evaluation.\n\nID: 42141512\nTitle: Antibiotic Metabolites Are an Overlooked Driver of Resistance Dissemination in Plant Systems.\nAbstract: Antibiotic pollution in agroecosystems is widely recognized, yet the risks posed by their metabolites remain insufficiently addressed. Using lettuce as a model, we investigated how tetracycline (TC) and its metabolites, anhydrotetracycline (ATC) and epitetracycline (ETC), contribute to the dissemination of antibiotic resistance genes (ARGs). TC primarily accumulated in roots and declined during translocation, whereas ATC exhibited greater persistence and became the predominant residue through in planta transformation. At environmentally relevant concentrations (\u22640.1 mg\u00b7L-1), ATC more effectively expanded the mobilizable resistome than the parent compound by inducing reactive oxygen species, activating the SOS response, increasing membrane permeability, and promoting RP4 plasmid conjugative transfer. These processes facilitated the acquisition of multidrug resistance and the colonization of plant tissues by human pathogens, including Stenotrophomonas maltophilia and Pseudomonas aeruginosa, thereby increasing ARG burdens in both rhizosphere and phyllosphere compartments. Metagenomic analysis further confirmed the coselection of nontetracycline ARGs, such as aph3'-I and catB, and the enrichment of efflux systems (acr/emr) in pathogenic bacteria. Our findings challenge the parent-compound-centered paradigm of antibiotic risk assessment by identifying ATC as a key high-risk driver of ARG dissemination in food plants and highlighting the need to incorporate transformation products into future management strategies.\n\nID: 42132390\nTitle: Evaluation of the combined efficacy of carvone and colistin against colistin-resistant Pseudomonas aeruginosa: in vitro and in vivo studies.\nAbstract: Pseudomonas aeruginosa (P. aeruginosa) is the primary pathogenic bacterium causing nosocomial-acquired infections, particularly in immunocompromised individuals. Owing to the abuse of colistin (COL), a frontline drug in clinical settings, the resistance rate of P. aeruginosa to COL has been escalating year by year, exerting a severe impact on public health. To solve this clinical problem, new therapeutic approaches are urgently required. This study initially proposes a strategy of using carvone in combination with COL to combat colistin-resistant Pseudomonas aeruginosa (COL-R P. aeruginosa). The checkerboard assay and time-kill assay validated the in vitro antibacterial action of this combination against COL-R P. aeruginosa. Furthermore, crystalline violet staining and scanning electron microscopy (SEM) confirmed that the combined treatment effectively inhibited biofilm formation. Moreover, the thigh infection model in neutropenic mice showcased the in vivo effectiveness of the combined therapy. In addition, the erythrocyte hemolysis experiment and the in vivo safety assessment revealed that the combination of carvone and COL exhibited a certain level of safety at effective concentrations. The synergistic antibacterial and antibiofilm mechanisms of carvone combined with COL may be associated with the inhibition of quorum-sensing gene expression, enhancement of bacterial inner and outer membrane permeability, and increased generation of reactive oxygen species. This study offered a new therapeutic strategy for COL-R P. aeruginosa infections.IMPORTANCEThe increasing prevalence of colistin-resistant Pseudomonas aeruginosa (COL-R P. aeruginosa) poses a significant threat to global public health, as it limits treatment options for severe infections. This study investigates the synergistic effects of carvone, a natural compound, combined with colistin (COL) to combat COL-R P. aeruginosa both in vitro and in vivo. The findings reveal that carvone can restore the susceptibility of COL-R P. aeruginosa to COL. By exploring this novel combination, the research aims to provide a potential alternative therapeutic strategy for COL-R P. aeruginosa infections. The findings could pave the way for new approaches to treat infections caused by this resilient pathogen.\n\nID: 42127741\nTitle: Photodynamic and antibiotic combination therapy against multidrug-resistant Pseudomonas aeruginosa wound infections in diabetic rats.\nAbstract: In our previous study, 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT) promoted chronic diabetic wound healing by reducing the microbial burden. However, the anti-bacterial efficacy of ALA-PDT is often compromised by limited light penetration into tissues. To increase the efficacy of ALA-PDT, this study assessed its combined use with the antibiotic ceftazidime in treating chronic diabetic wounds and examined the potential mechanism of action. The results indicated that the combination of ALA-PDT and ceftazidime synergistically inhibited the growth of multidrug-resistant Pseudomonas aeruginosa. The treatment also prevented the formation of bacterial biofilm, delayed the development of antibiotic resistance, inactivated pyocyanin, and exerted a prolonged post-antibiotic effect. The mechanism supporting the synergistic antibacterial effect might involve ALA-PDT-mediated reactive oxygen species generation, leading to bacterial cell structure destruction, increased membrane permeability, and cellular ceftazidime uptake. In a full-thickness skin defect infection model in rats with diabetes, the bactericidal and wound closure rates were highest in the combination therapy group. Transcriptomics analysis of wound tissues revealed that the differentially expressed genes between the combination therapy and model groups were mainly enriched in the IL-17, AKT-STAT, and VEGF signaling pathways. Molecular biology experiments illustrated that the combination therapy might regulate the expression of IL-17, activate the JAK-STAT axis, increase p-JAK2 and p-STAT3 expression, and decrease SOCS3 expression, ultimately leading to Ki-67, CD31, and VEGF upregulation and exerting beneficial effects on angiogenesis, collagen deposition, and tissue regeneration. Overall, PDT and antibiotic combination therapy offers an efficient approach to treat infections in diabetic wounds.\n\nID: 42113464\nTitle: Integrating resistance biology, virulence networks, and precision therapeutics against multidrug-resistant Pseudomonas aeruginosa.\nAbstract: Multidrug-resistant Pseudomonas aeruginosa (MDR P. aeruginosa) has emerged as a major threat in contemporary clinical microbiology, driven by the convergence of extensive antimicrobial resistance, biofilm-mediated persistence, and tightly coordinated virulence regulation. Global surveillance reveals a sustained increase in MDR and carbapenem-resistant P. aeruginosa (CRPA), characterized by marked regional heterogeneity and the dissemination of high-risk international clones. Conventional antibiotic-centered strategies are increasingly compromised by the interplay between intrinsic resistance determinants, including low outer membrane permeability, multidrug efflux systems, and inducible \u03b2-lactamase, and acquired mechanisms such as carbapenemases, target-site mutations, and adaptive biofilm-associated tolerance. This review presents a systems-level framework that integrates global epidemiology, resistance architecture, clinical manifestations of acute and chronic infections, pathogenicity, diagnostic innovation, and emerging therapeutic strategies into a cohesive translational perspective. Emphasizing the mechanistic convergence of resistance, persistence, and virulence reframes MDR P. aeruginosa as a dynamically regulated pathogenic network rather than solely a drug-resistant organism. Next-generation interventions are critically examined within the context of precision diagnostics and antimicrobial stewardship. Taken together, these developments signal a shift from antibiotic escalation toward integrated, precision-informed, and evolution-aware therapeutic frameworks. Sustainable control of MDR P. aeruginosa will require coordinated implementation of targeted pathogen disruption, rapid molecular diagnostics, robust stewardship strategies, hygiene measures, and antimicrobial resistance surveillance to redefine antimicrobial practice as we get closer to the post-antibiotic era.\n\nID: 42096524\nTitle: Recovering viable bacteriophages from human milk: implications for sample storage and processing.\nAbstract: Molecular methods have shown bacteriophage diversity in human milk, but this does not reflect viability, particularly within donor human milk which has been subjected to multiple freeze-thaw cycles and heat treatment. Our aim was to isolate bacteriophages from frozen human milk and explore the effects of sterilization and storage on bacteriophage survival. Twenty frozen human milk samples were chosen for bacteriophages isolation. Analysis showed that these samples stored for 12 months at -20\u00b0C did not contain viable bacteriophages. We artificially inoculated 10 human milk and 10 water control samples with Escherichia coli bacteriophage T4 and subjected them to various treatments. We found that ultraviolet-C irradiation significantly inactivated E. coli phage T4 (P\u00a0<\u00a00.001), with greater inactivation observed in skimmed milk (P <\u00a00.001) than whole milk. In contrast, Holder and High Temperature Short Time pasteurization had no significant effect (P\u00a0>\u00a00.05). The E. coli bacteriophage T4 was better preserved at 4\u00b0C than at room temperature over 48 h. Over 90 days of storage, bacteriophage viability was higher at -80\u00b0C (31.6%) than at -20\u00b0C (9.4%). Future work on bacteriophage isolation from human milk should consider the use of fresh samples whenever possible. Where samples are stored prior to analysis this should be at a refrigerated temperature for up to 48 h, and if samples are to be stored longer term, then -80\u00b0C is suitable for up to three months and preferable to -20\u00b0C, with storage only up to seven days.\n\nID: 42072119\nTitle: Harmine Targets Peroxiredoxin 6 to Enhance Macrophage Immunity Against Pseudomonas plecoglossicida in Ayu (Plecoglossus altivelis).\nAbstract: Pseudomonas plecoglossicida causes bacterial hemorrhagic ascites in ayu (Plecoglossus altivelis), a lethal disease characterized by abdominal distension with hemorrhagic ascites, multifocal organ hemorrhages, and histopathologically evident hepatocellular necrosis and inflammatory infiltration. The lack of effective treatments exacerbates mass mortalities, posing a significant threat to aquaculture. Given the severe pathogenesis of P. plecoglossicida infection-which involves bacterial colonization, tissue necrosis, and host immune dysregulation-effective therapeutic strategies are urgently needed. Through a screen of traditional Chinese medicine monomers, we identified harmine, an indole alkaloid derived from Peganum harmala seeds, as a potent agent against this pathogen. In vivo, harmine exhibited direct bactericidal activity by disrupting membrane integrity, as evidenced by increasing membrane permeability, and inhibiting biofilm formation. In an ayu infection model, harmine significantly increased host survival, reduced tissue bacterial load, and enhanced innate immunity by augmenting monocyte/macrophage phagocytosis and bactericidal capacity while suppressing pro-inflammatory cytokine release and apoptosis. Mechanistically, the Drug Affinity Responsive Target Stability assay was used to identify the molecular target of harmine, followed by functional validation through PRDX6-knockdown experiments. Harmine exhibited direct bactericidal activity by disrupting membrane integrity and inhibiting biofilm formation. In the ayu infection model, harmine significantly increased host survival, reduced tissue bacteria1 load, and enhanced innate immunity by augmenting monocyte/macrophage system and bactericidal capacity while suppressing pro-inflammatory cytokine release and apoptosis, the latter likely through modulation of PRDX6-mediated oxidative stress and downstream caspase signaling. Mechanistically, DARTS revealed that harmine binds to peroxiredoxin 6 (PRDX6), a multifunctional enzyme possessing peroxidase, phospholipase A2, and lysophosphatidylcholine acyltransferase activities. This binding liberates TNF receptor-associated factor 6 (TRAF6), facilitating its mitochondrial translocation and association with the ECSIT signaling integrator complex, thereby amplifying mitochondrial reactive oxygen species (mROS) production and potentiating macrophage-mediated bacterial killing. These findings establish harmine as a promising therapeutic candidate for controlling P. plecoglossicida infections and underscore the value of host-directed immunomodulation derived from natural products in aquaculture medicine.\n\nID: 42043570\nTitle: Bacteriophage survival and ARG dissemination from wastewater treatment plants to the environment.\nAbstract: The proliferation of antibiotic resistance genes (ARGs) represents a critical global health threat, with wastewater treatment plants (WWTPs) identified as major hotspots for resistance amplification and dissemination. While bacterial conjugation has been extensively studied, bacteriophages are emerging as significant but underestimated vectors for ARG transfer via transduction. We hypothesize that phages are capable of withstanding disinfection and exploiting diverse bacterial hosts in receiving environments, thereby functioning as active vectors of ARG dissemination rather than passive genetic reservoirs. Meta-analysis of disinfection efficacy data (n\u2009=\u200979 experimental observations, 6 technology categories) reveals significant differences in log\u2081\u2080 reduction across disinfection technologies (Kruskal-Wallis: H\u2009=\u200925.96, df\u2009=\u20095, p\u2009<\u20090.0001). Ozonation was significantly more effective than chlorination (p\u2009<\u20090.001), membrane processes (p\u2009=\u20090.003), UV irradiation (p\u2009=\u20090.005), and PAA/thermal treatment (p\u2009=\u20090.010). Phage persistence in receiving waters follows a 1-4\u00a0week timeline modulated by temperature (Q\u2081\u2080\u2009~\u20092-3), solar UV, and water chemistry. Broad host range phages have the potential to transfer ARGs to environmentally dominant genera (Aeromonas, Pseudomonas, Vibrio), and sub-inhibitory antibiotics may induce prophages and enhance bacterial competence, creating synergistic conditions that could accelerate resistome evolution. This review underscores the need for integrated approaches combining phage-targeted disinfection with ecological monitoring to effectively restrain the spread of antibiotic resistance.\n\nID: 42041309\nTitle: TXA11114: Discovery of an In Vivo Efficacious Efflux Pump Inhibitor (EPI) That Potentiates Levofloxacin Against Pseudomonas aeruginosa.\nAbstract: Objectives: Multidrug-resistant (MDR) Pseudomonas aeruginosa represents a major clinical challenge, driven in part by resistance-nodulation-division (RND) efflux pumps that reduce intracellular antibiotic concentrations and limit the efficacy of many antibacterial agents, including fluoroquinolones. The aim of this study was to identify and characterize TXA11114 as a small-molecule efflux pump inhibitor (EPI) capable of restoring the activity of the fluoroquinolone levofloxacin against MDR P. aeruginosa. Methods: The antibacterial activity of the TXA11114-levofloxacin combination was evaluated using minimum inhibitory concentration (MIC) assays against panels of clinical isolates. Mechanistic studies included levofloxacin accumulation assays, ethidium bromide accumulation assays, outer-membrane permeability measurements, and whole-genome sequencing of mutants with altered potentiation phenotypes. In vivo efficacy was evaluated in murine thigh and lung infection models, while preliminary safety and drug-like properties were assessed using cytotoxicity assays and in vitro ADME profiling. Results: The TXA11114-levofloxacin combination produced > 1 log10 CFU reductions in bacterial burden in murine thigh and lung infection models, exceeding the activity of levofloxacin monotherapy. TXA11114 markedly potentiated levofloxacin activity, producing substantial reductions in levofloxacin MIC values across multiple MDR clinical isolates, and also enhanced the activity of several additional efflux pump substrates, including \u03b2-lactams, tetracyclines, chloramphenicol, and trimethoprim-sulfamethoxazole. Mechanistic experiments demonstrated increased intracellular accumulation of efflux substrates without evidence of nonspecific membrane disruption, and mutations in ompH were associated with altered potentiation phenotypes. Conclusions: The TXA11114-levofloxacin combination produced significantly greater bacterial reductions than levofloxacin monotherapy in murine infection models. Levofloxacin was selected because fluoroquinolone resistance in P. aeruginosa is frequently driven by efflux-mediated mechanisms. While this study focused on levofloxacin potentiation, future work will evaluate additional efflux pump substrates and further define the molecular target of TXA11114.\n\nID: 42384803\nTitle: Dimer asymmetry in signaling of blue light sensor histidine kinases.\nAbstract: Photoreceptor sensory histidine kinases (SHKs) couple light absorption to conformational changes regulating two-component signaling. Despite their importance and widespread use in optogenetics, the underlying structural signaling mechanisms remain poorly understood. Here, we engineered dimeric SHKs based on Pseudomonas putida short light-oxygen-voltage (LOV) proteins, determined their crystal structures, and investigated their signaling mechanisms. Regardless of illumination, the structures adopted a light-state like LOV-LOV dimer with symmetric/straight kinase modules. In contrast, small-angle x-ray scattering together with functional assays revealed pronounced light-dependent rearrangements in solution and allowed the assignment of the kinase-ON dark state to an asymmetric/kinked conformation, whereas the light state adopts a symmetric/straight structure. Comparative analyses of natural and engineered SHKs identified conserved motifs linking light-induced LOV domain rotation to kinase activity. The findings highlight the central role of dimer asymmetry and flexibility in SHK signaling, thereby not least informing the engineering of new light-responsive signaling systems.\n\nID: 42377607\nTitle: In vitro antibiofilm activity of dermcidin derived peptides against Pseudomonas aeruginosa and Staphylococcus aureus pathogens.\nAbstract: Pseudomonas aeruginosa and Staphylococcus aureus are major opportunistic pathogens capable of developing antibiotic resistance and forming device-associated biofilms, which complicate clinical management. The present study aimed to investigate the antimicrobial and anti-biofilm properties of dermcidin-derived peptides against clinical isolates of these bacteria. Clinical isolates of methicillin-susceptible and methicillin-resistant S. aureus (MSSA and MRSA), as well as carbapenem-susceptible and carbapenem-resistant P. aeruginosa (CSPA and CRPA), were examined for their susceptibility to dermcidin-derived peptides (DCD-1\u00a0L, SSL-23, and SSL-25). The in vitro inhibitory activity of the peptides on bacterial adhesion and biofilm formation was evaluated at sub-MIC levels, while their biofilm-disrupting potential was assessed on mature biofilms. Furthermore, the expression of key biofilm-associated and quorum-sensing genes was quantified using qRT-PCR following peptide exposure. Dermcidin-derived peptides markedly inhibited bacterial attachment and biofilm formation at sub-inhibitory concentrations (1/2, 1/4, and 1/8 MIC). In addition, they exhibited strong biofilm eradication activity at higher concentrations (8\u00d7-64\u00d7 MIC). Gene expression analysis revealed significant down-regulation of adhesion- and quorum-sensing-related genes in both S. aureus and P. aeruginosa after treatment. The results suggest that dermcidin-derived peptides, regardless of their net charge, possess potent inhibitory effects on bacterial attachment and biofilm development. These findings highlight their potential as promising therapeutic agents for the prevention and control of biofilm-associated infections.\n\nID: 42359998\nTitle: Coumarins Disrupt Cell-Cell Communication and Virulence in Priority Pathogens: Targeting the PQS Signalling System in Pseudomonas aeruginosa.\nAbstract: Cell-to-cell communication in microbial systems is known for its vital role in cellular signalling and gene expression. A specific form termed Quorum Sensing (QS) has received considerable attention since its discovery in the marine symbiont Aliivibrio fischeri. QS-controlled microbial functions are associated with bacterial virulence, pathogenicity, host-microbe interactions, and biofilm development. Interference in these signalling systems can modulate microbial virulence and pathogenicity, and microbial infection caused by drug-resistant pathogens. Plant-derived phytochemicals are considered a promising candidate, with coumarins emerging as significant plant-derived signalling molecules shaping microbiome dynamics and pathogen behaviours from a broad spectrum of ecosystems. Here we explored the role of natural and synthetic coumarin compounds in the control of signalling and virulence traits in Pseudomonas aeruginosa and other priority bacterial pathogens, including the fungal opportunist Aspergillus fumigatus. We uncovered an important 'hydroxylation-bias' favouring coumarin, umbelliferone (7-OH), and 6-hydroxy-coumarin (6-OH) in the specific competitive inhibition of the Pseudomonas Quinolone Signal (PQS), associated with reduced activity of a PqsR translational fusion and suppression of pyocyanin production. Conversely, while esculetin (6,7-OH) was most effective at Acyl Homoserine Lactone (AHL) QS biosensor inhibition, it did not affect PQS production. Anti-biofilm activity of coumarins against P. aeruginosa was independent of initial attachment but linked to changes in exopolysaccharide production. As the very real threat posed by antimicrobial resistance persists, these data support a role for phytochemicals such as coumarins in delivering an ecological solution to dysbiosis in the host-microbe interaction.\n\nID: 42358264\nTitle: From fungal diversity to antimicrobial innovation: the potential of biotransformation in the era of resistance.\nAbstract: Antimicrobial resistance (AMR) continues to outpace the development of new anti-infective agents, particularly against priority bacterial pathogens such as Acinetobacter baumannii, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Staphylococcus aureus, as well as clinically relevant fungi including Candida auris. In this scenario, biotransformation has emerged as a complementary innovation strategy for antimicrobial discovery because it expands the chemical space around bioactive scaffolds through selective enzymatic or whole-cell modification. Among the available biocatalysts, fungi are especially attractive due to their metabolic plasticity and broad enzymatic repertoire, including cytochrome P450 monooxygenases, unspecific peroxygenases, laccases, peroxidases, and hydrolases. Current evidence shows that fungal systems can mediate regio- and stereoselective transformations of xenobiotics, aromatics, steroids, terpenes, and lipids, generating structurally refined metabolites of pharmacological and biotechnological interest. This narrative review discusses where fungal biotransformation currently stands as a platform for antimicrobial innovation, highlighting representative enzyme-characterized examples, the main fungal groups and catalytic systems involved, and the experimental workflows used to evaluate these processes. Particular emphasis is given to assay design with growing cells, resting cells, and isolated enzymes, as well as to analytical monitoring by time-course sampling, LC-HRMS/MS, dereplication, molecular networking, isolation, and structural elucidation. Overall, fungal biotransformation is presented as a discovery-enabling platform that links biodiversity, enzymatic catalysis, analytical chemistry, and biological prioritization in the search for new anti-infective molecules.\n\nID: 42350929\nTitle: Essential Oils and Their Multifunctional Activities Against Pseudomonas aeruginosa: Current Evidence and Perspectives.\nAbstract: Pseudomonas aeruginosa is an opportunistic pathogen responsible for acute and chronic infections and is characterized by a remarkable ability to develop antibiotic resistance. This has prompted increasing interest in alternative or complementary antimicrobial strategies, including the use of essential oils (EOs), which are complex mixtures of plant-derived volatile compounds with documented biological activities. This review aims to summarize and discuss the current evidence on the antimicrobial, antibiofilm, and anti-virulence activities of EOs against P. aeruginosa, with particular emphasis on their mechanisms of action, synergistic interactions with antibiotics, and limitation to the possible clinical applicability. A large number of studies, mainly conducted in vitro, indicate that EOs and their major constituents can impair P. aeruginosa viability and pathogenicity through multiple mechanisms. In addition, several EOs or purified terpene components exhibit synergistic effects when combined with conventional antibiotics, enhancing antimicrobial efficacy. However, in vivo evidence remains limited, largely restricted to topical infection models, while clinical studies in humans are currently lacking. Significant challenges related to chemical variability, toxicity, safety, standardization, and regulatory classification also emerge from the literature. Although EOs show considerable promise as antimicrobial and anti-virulence agents against P. aeruginosa, their current role should be viewed primarily as adjunctive or alternative strategies rather than as standalone systemic therapies. Future progress will depend on the development of standardized and safer formulations, advanced delivery systems, and well-designed in vivo and clinical studies.\n\nID: 42340134\nTitle: Acinetobacter baumannii in the Age of Antimicrobial Resistance: Clinical Impact, Therapeutic Approaches, and Vaccine Development.\nAbstract: Acinetobacter baumannii is a globally prevalent Gram-negative pathogen responsible for a substantial proportion of healthcare-associated infections, particularly in intensive care units. Its ability to persist in hospital environments, form biofilms on medical devices, and evade host immune responses has contributed to the rapid emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains. This narrative review was conducted through a comprehensive literature search of PubMed, Scopus, Web of Science, and Google Scholar, focusing on studies published primarily over the past two decades. The review summarizes global epidemiology, vulnerable populations, mechanisms of antimicrobial resistance, clinical and economic impacts, and current and emerging therapeutic strategies. The advances in alternative treatments, including antimicrobial peptides, bacteriophage therapy, and vaccine development, are also discussed. In addition to summarizing existing knowledge, this review critically examines the key limitations underlying current therapeutic and vaccine strategies, including rapid resistance evolution, immune evasion, and antigenic variability. It further identifies major translational gaps and proposes future directions integrating systems biology and multitarget approaches. Although preclinical studies demonstrate the promising efficacy of several vaccine candidates, clinical trials in humans remain necessary to confirm their safety and effectiveness.\n\nID: 42334695\nTitle: Computational exploration and in vitro validation of anti-quorum sensing potential of phytochemicals from Coleus amboinicus.\nAbstract: Development of antimicrobial resistance in bacteria is a major concern. The study of quorum sensing (QS), the bacterial communication system that coordinates important events in an infection, opens a new avenue for treating infections. QS helps in biofilm formation which acts as a physical barrier and alters the microenvironment which traps the molecules or slows down the antibiotic diffusion making them less effective. Since the standard drugs are not very effective against bacteria anymore, demand for the discovery of other alternatives arises. Phytochemicals extracted from commonly used plants like Coleus amboinicus, known to have antimicrobial properties, can be used to develop novel drugs against quorum sensing and hence suppress bacterial infection. Here, we have identified a set of phytochemicals from C. amboinicus whose drug-like properties were predicted using SwissADME and their interactions with the targets involved in QS in Pseudomonas aeruginosa, Vibrio harveyi and Chromobacterium violaceum were studied by performing molecular docking using PyRx software. Beta-amyrin, chrysoeriol and apigenin were found to be the top scored molecules with docking scores of -9.3, -11.3, and -\u200911.1\u00a0kcal/mol respectively, and were considered for molecular dynamics simulation using GROMACS software. This was followed by in vitro tests such as Agar well diffusion, Scanning electron microscopy, Pyocyanin assay and Crystal violet assay. Erythromycin was used as the standard drug and as a positive control to validate the results. Based on both in vitro and in silico studies, the phytochemicals from C. amboinicus have the potential to be inhibitors of quorum sensing targets. These findings are preliminary and should be interpreted as hypotheses to be tested experimentally rather than as established mechanisms.\n\nID: 42327744\nTitle: RNA modifications shape innate immunity and cellular adaptation during bacterial respiratory infection.\nAbstract: Gram-negative bacteria are clinically significant pathogens responsible for life-threatening infections, including respiratory infections. These can be acute or persistent and can exacerbate existing chronic diseases, such as cystic fibrosis, COPD and lung cancer. In this review, we use Pseudomonas aeruginosa as a model organism that demonstrates the molecular complexity of host-pathogen interactions during lower airway infection. Specifically, we focus on RNA modifications and show that they, on the one hand, regulate bacterial fitness and pathogenicity, and on the other control the execution of an effective host innate immune response. Furthermore, we examine the role of epigenetic and epitranscriptomic modifications in the immune dysregulation observed in sepsis, with an emphasis on sepsis-induced lung injury. Innate immune memory -\u00a0a cellular adaptation mechanism to primary microbial stimulation - results in training or tolerization of host cells towards secondary immune challenges. While fundamentally grounded in epigenetic and metabolic reprogramming, we propose that it can crosstalk with epitranscriptomic regulation. To overcome limitations imposed by animal models when investigating microbe-induced epitranscriptomic dynamics, we highlight physiologically-relevant in vitro tissue models that can complement work performed in vivo. Ultimately, a detailed understanding of the RNA modification landscape regulating host-pathogen interactions will help us identify new therapeutic targets and molecular pathways to better manage the clinical symptoms of bacterial respiratory infections and address the growing challenge of antimicrobial resistance.\n\nID: 42320465\nTitle: Phosphorus stress and spatial confinement lower the quorum-sensing activation threshold for phenazine production in Pseudomonas synxantha.\nAbstract: Bacteria often coordinate collective behaviors such as biofilm formation and secondary metabolite production through quorum sensing (QS), a regulatory system traditionally linked to high cell density. However, in environments such as soil, where microbial populations are spatially fragmented, sparse, nutrient-limited, and subject to mass transport, the mechanisms that enable QS-dependent processes remain incompletely understood. Here, we investigate the regulation of a secreted redox-active metabolite, phenazine-1-carboxylic acid (PCA), in Pseudomonas synxantha 2-79, a model rhizobacterium, under phosphorus (P) limitation, a persistent stress in many soils. Using a combination of microscopy and molecular genetic approaches, we show that P limitation sensitizes the QS activation threshold by an order of magnitude, enabling phenazine induction at relatively low population densities compared with P-replete conditions. This induction is abolished in QS-deficient mutants and restored by the addition of exogenous acyl-homoserine lactone (AHL), demonstrating that QS remains essential, but its threshold becomes environmentally tuned. Under P limitation, spatial confinement and pore saturation levels further shape the timing and location of induction, illustrating how physical structure and nutrient stress can modulate bacterial activities. Moreover, P stress confers both collaborative and competitive advantages, enabling P. synxantha to undergo low-cell-density AHL cross-induction with related Pseudomonas spp. and to suppress other rhizobacteria. Lastly, on plant roots, phenazine biosynthetic genes are more strongly induced under P limitation. These findings illustrate how the nutrient status of an environment can modulate the onset of QS, enabling quorum-regulated behaviors to activate at lower thresholds.\n\nID: 42318016\nTitle: Microbial and host innate immune factors affecting the persistence of Staphylococcus aureus in cystic fibrosis airways.\nAbstract: Chronic bacterial respiratory infections by Staphylococcus aureus are a hallmark of cystic fibrosis (CF) lung disease, affecting up to 80% of all people with CF by their mid-teens. S. aureus is able to survive and persist in the CF lung despite robust neutrophilic inflammation. As neutrophils are the immune system's front line of defense against bacteria, the persistent nature of S. aureus infections in CF indicates both a defect in the ability of neutrophils to kill S. aureus and an enhanced ability of the bacteria to survive. S. aureus persistence in the CF lung is driven by both microbial and host, genetic and microenvironmental, factors. There doesn't seem to be one unifying feature that makes S. aureus more virulent in the CF lung as several factors have been proposed to aide its survival. These include increased resistance to antibiotics, the ability to form small colony variants, biofilm formation, co-infection with Pseudomonas aeruginosa, and several virulence factors such as the accessory gene regulatory system, leukocidins, and staphylococcal protein A. A variety of host factors also affect the ability of neutrophils to kill S. aureus in the CF lung. Defects in the function of the cystic fibrosis transmembrane conductance regulator, the genetic cause of CF, affect phagolysosomal killing and lead to increased formation of neutrophil extracellular traps, which are less effective at killing S. aureus. Additionally, data suggest that factors within the CF lung microenvironment also affect neutrophilic killing of S. aureus. However, more research is needed to clearly identify what these environmental factors may be. This review article summarizes the current knowledge on the clinical relevance of S. aureus lung infections in CF, on microbial and host mechanisms promoting S. aureus survival in the CF lung, and on details of neutrophil-S. aureus interactions in CF. By understanding how S. aureus is able to survive in the CF lung and why neutrophils are unable to kill this bacterium, it could be possible to identify potential therapeutic targets to alleviate the consequences of S. aureus respiratory infection in CF.\n\nID: 42306840\nTitle: Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis.\nAbstract: Gram-negative bacteria produce nonulosonic acids, a family of nine-carbon sugars that mimic host sialic acids and may contribute to bacterial virulence. The nonulosonic acid C8-epimeric 5,7-di-N-acetyllegionaminic acid (8-epi-Leg5,7Ac2) is a component of the K-locus 49 (KL49) capsule of hypervirulent Acinetobacter baumannii, and its epimerization is proposed to be mediated by ElaA, ElaB, and ElaC. We identified a KL49 strain that induces lethal sepsis in mice and found deletion of elaA, elaB, or elaC abolished lethality and markedly reduced capsule production. Crystal structures of ElaB, ElaA, and ElaC revealed conserved N-acetyl recognition underlying CMP-Leg5,7Ac2 synthesis and regioselective C8 epimerization. Together, these genetic, structural, and in vivo findings identify ElaABC as potential antivirulence targets in emerging hypervirulent KL49 A. baumannii strains.\n\nID: 42305438\nTitle: Phosphatase PTP-4 downregulates ATLN-1-mediated host defense against Pseudomonas aeruginosa infection in Caenorhabditis elegans.\nAbstract: The p38 MAPK pathway governs the core innate immune response in Caenorhabditis elegans (C. elegans), yet the negative regulatory networks preventing immune overactivation-and their potential as therapeutic targets-remain elusive. We aimed to identify novel phosphatase checkpoints in host defense, elucidate their molecular mechanisms, and validate their druggability using small-molecule interventions. We performed a genome-wide RNAi screen of 166 phosphatase genes in C. elegans infected with Pseudomonas aeruginosa (PA14) to identify key regulators. The molecular mechanism was dissected using yeast two-hybrid screening, Co-IP, and mutagenesis assays. Furthermore, a small-molecule screen was performed to identify compounds capable of interfering with PTP-4 function, followed by Surface Plasmon Resonance (SPR), molecular docking, and structural biology approaches to characterize compound-PTP-4 interactions. PTP-4 was identified as a critical negative regulator of immunity. Genetic deficiency of ptp-4 significantly enhanced host resistance via hyperactivation of the p38 MAPK (PMK-1) pathway. Mechanistically, PTP-4 physically interacts with ATLN-1, an ER-shaping GTPase, through its phosphatase domain, thereby suppressing immune activation. Crucially, baicalin was identified through compound screening as an inhibitor of P. aeruginosa infection. Structural and biochemical analyses revealed a dual mechanism of action: baicalin directly binds to the PTP-4/ATLN-1 interface with high affinity (KD = 28.69\u00a0\u03bcM) to allosterically disrupt their complex formation, while concurrently downregulating PTP-4 protein expression. This \"dual-hit\" inhibition mimics the genetic loss of ptp-4, effectively unleashing the innate immune response. Our study uncovers the PTP-4/ATLN-1 axis in the control of P. aeruginosa infection. Importantly, we provide the first proof-of-concept that this axis is a druggable target. By demonstrating that baicalin boosts host immunity through the specific dismantling of the PTP-4/ATLN-1 complex, we highlight a novel therapeutic strategy for combating bacterial infections.\n\nID: 42304313\nTitle: Chemical profile, anti-biofilm and antioxidant activities of Cymbopogon citratus (DC.) Stapf essential oil.\nAbstract: The urgent need for novel antimicrobial agents arises from the escalating threat of antibiotic-resistant pathogens. Tackling the resistance mechanisms through the application of resistance modifying agents in combination to antimicrobials represents an effective strategy to combat antimicrobial resistance and to enhance the antimicrobial activity. Screening of plant extracts, essential oils and their active compounds for potential resistance modifying properties has proven effective on both a small and large scale. In this study, we define the metabolomic profile of essential oils extracted from different parts of Cymbopogon citratus (DC.) Stapf (lemongrass), and characterize their antioxidant and virulence attenuating activities. The major active ingredients of essential oils extracted from different parts of Cymbopogon citratus (lemongrass) were identified by GC-MS analysis. The minimum inhibitory concentration (MIC) of the essential oils against P. aeruginosa PAO1, Staphylococcus aureus ATCC 6538, and Candida albicans ATCC 10,261 was determined using the broth microdilution assay. Antibiofilm and antiprotease activities were phenotypically evaluated for the extracted lemongrass essential oils for the same standard strains and clinical isolates for the same microbes. Also, the effects on microbial virulence were validated by RT-qPCR against a subset of genes regulating biofilm, quorum sensing, and stress response in P. aeruginosa, and S. aureus. Furthermore, the antioxidant activities of the different essential oils extracted were evaluated using DPPH, \u03b2-carotene/linoleic acid and FRAP methods. GC-MS analysis of the essential oils of Cymbopogon citratus revealed the presence of 47 different compounds distributed in the different plant organs. Active constituents such as geranial, neral, myrcene, nerolic acid, linalool, iso-citral, trans iso-citral, and neryl acetate were more abundant in the essential oil extracted from leaves (89.77%), followed by stems (82.92%) and finally roots (52.02%). S. aureus, and C. albicans were more sensitive to C. citratus essential oils than Gram negative P. aeruginosa. Incorporation of sub-MIC doses of essential oils into the culture media was sufficient to disrupt the formation of microbial biofilms in P. aeruginosa, S. aureus, and C. albicans, and to inactivate the proteolytic activities of microbial proteases. The essential oils of C. citratus showed promising and broad-spectrum biofilm eradicating activity. Sub-MIC doses of lemongrass oil dramatically reduced the expression of relA, pslA, and spoT in P. aeruginosa, and agrA, icaA, and sigB in S. aureus indicating a broad-spectrum anti-virulence activity. Our study identifies C. citratus essential oils as potential virulence-attenuating agents. Essential oils extracted from the leaves, stems, and roots of C. citratus exhibited significant antimicrobial, anti-biofilm, anti-virulence, and antioxidant activities, effectively combating microbial resistance. These findings suggest that C. citratus essential oils could be a valuable natural alternative in the fight against resistant pathogens.\n\nID: 42301347\nTitle: Single and multiple investigation activity potential luteolin against Candida albicans, Escherichia coli and Pseudomonas aeruginosa.\nAbstract: Candida albicans is an opportunistic pathogen that can cause invasive infections, especially under conditions of immunosuppression and dysbiosis. Its presence alongside Pseudomonas aeruginosa and Escherichia coli may lead to polymicrobial biofilm-related infections. Due to rising antimicrobial resistance, alternative therapies are being explored, including luteolin, a natural flavonoid with reported in vitro antimicrobial activity. This study evaluated the in vitro antimicrobial and antibiofilm effects of luteolin against C. albicans, E. coli, and P. aeruginosa, both individually and in combination. Methods involved determining minimum inhibitory concentrations, using scanning electron microscopy, fibroblast viability tests, ELISA-based cytokine measurements, and RT-qPCR analysis of key biofilm- and quorum-sensing-related genes (luxS, lasI, and ALS1). MIC values were 0.011\u00a0mg/mL for individual strains and 0.046\u00a0mg/mL for the polymicrobial mixture. Luteolin treatment reduced microbial adherence and improved fibroblast viability compared to infected controls. Infection increased IL-1\u03b2 levels and decreased IL-10 levels, effects that luteolin partially reversed. RT-qPCR showed downregulation of selected biofilm-related genes at 2\u00d7MIC. These findings demonstrate luteolin's measurable antimicrobial and anti-biofilm effects in vitro under controlled laboratory conditions, supporting further validation in preclinical models to assess translational potential.\n\nID: 42297082\nTitle: TBK1 associates with TRIF and TRAF3 related IRF3, IRF7, and type I IFN signaling in large yellow croaker Larimichthys crocea.\nAbstract: TANK-binding kinase 1 (TBK1) plays a central role in the host's defense system. In this research, we identified and analyzed the TBK1 ortholog from large yellow croaker (Larimichthys crocea) and investigated its function in the host innate immunity. The obtained ORF of Lc-TBK1 is 2172 bp and encoding a 723 aa protein. Subcellular localization analysis demonstrated that Lc-TBK1 predominantly resides in the cytoplasm. Lc-TBK1 showed broad expression across multiple tissues, and its transcript abundance was particularly high in the muscle. Its transcription was significantly upregulated after challenge with poly I:C, LPS, PGN, and Pseudomonas plecoglossicida. Overexpression of Lc-TBK1 activated IRF3, IRF7, and IFNd promoters, and such promoter activation were enhanced when Lc-TBK1 co-expressed with Lc-TRAF3 and Lc-TRIF. Co-immunoprecipitation assays confirmed direct interactions between Lc-TBK1 and several key adaptors, including Lc-TRIF, Lc-MAVS_tv1, Lc-MAVS_tv2, Lc-TRAF3, and Lc-TRAF6. Subsequent co-expression analyses revealed adaptor-specific modulation of antiviral gene transcription: Lc-TRIF and Lc-TRAF3 synergistically enhanced RSAD2, IRF3, and IRF7 expression, whereas Lc-MAVS isoforms attenuated these responses. Overall, our findings demonstrate that Lc-TBK1 signaling is differentially regulated by specific adaptor proteins, providing new insights into the evolutionary conservation and diversification of antiviral immune mechanisms in teleost.\n\nID: 42294676\nTitle: Disruption of cysteine metabolism leads to synthetic lethality and in vivo fitness impairment in Acinetobacter baumannii.\nAbstract: Acinetobacter baumannii is a critical nosocomial pathogen that causes infections in diverse host niches, including the respiratory tract, bloodstream, and urinary tract. Considering the contemporary landscape of antibiotic resistance, alongside targeting resistance determinants, there is a need to identify novel and alternative targets for therapeutic intervention. Central metabolism plays a major role in the success of a pathogen and represents a pool of plausible drug targets. However, metabolic networks are inherently complex and often employ redundant pathways to ensure the supply of essential metabolites. In our efforts to delineate the metabolic pathways contributing to the pathophysiological fitness of A. baumannii, we focused on biosynthesis and uptake mechanisms that maintain intracellular cysteine homeostasis. Cysteine is one of the least abundant amino acids in proteins; however, it is crucial for the folding and catalytic activity of enzymes involved in diverse pathophysiological pathways. We show that A. baumannii possesses two partially redundant serine acetyltransferases involved in cysteine biosynthesis. Disruption of cysteine biosynthesis affects the intracellular cysteine pool, leading to metabolic dysregulation. The metabolic dysregulation further leads to a defect in cellular bioenergetics, oxidative stress mitigation, and antibiotic stress survival in vitro and in vivo. Combinatorial disruption of cysteine biosynthesis and cystine transport results in synthetic lethality and fitness attenuation within the host. Our work provides insights into the metabolic complexities and vulnerabilities of A. baumannii and underscores the therapeutic potential of targeting pathways that sustain cysteine homeostasis, including combination strategies, to combat infections caused by this priority pathogen.IMPORTANCEAcinetobacter baumannii is a critical nosocomial pathogen, and the rising prevalence of antibiotic resistance in this organism necessitates the identification of novel therapeutic targets. Central metabolism, particularly amino acid metabolic pathways, represents a promising yet underexplored area for such interventions. Cysteine, a sulfur-containing amino acid, is essential for the activity of different enzymes involved in key physiological processes. In this study, we demonstrate that the cysteine biosynthesis pathway plays a critical role in maintaining metabolic homeostasis and survival under antibiotic stress while exhibiting functional redundancy with the cystine uptake system in sustaining in vivo fitness in A. baumannii . Simultaneous disruption of cysteine biosynthesis and uptake results in synthetic lethality and a marked fitness defect in a murine pneumonia model. Our work reveals metabolic complexities and highlights the metabolic vulnerabilities of A. baumannii, which can be further explored for therapeutic interventions to curb infections caused by this priority pathogen.\n\nID: 42285423\nTitle: Advances in Quorum-Sensing Inhibitors as Novel Therapeutic Targets.\nAbstract: The growing antimicrobial resistance (AMR) has again prompted consideration of therapeutic strategies that reduce bacterial virulence rather than directly impairing viability. Quorum sensing (QS) is a density-dependent signaling network that controls the production of virulence factors, biofilm formation, metabolic reorganization, and interspecies communication in most clinically important pathogens. Quorum-sensing inhibitors (QSIs) target such coordinated behaviors by blocking autoinducer biosynthesis, signal degradation, receptor activation, or transcriptional networks downstream of these receptors. Naturally occurring, synthetic small molecules; synthetic, engineered peptide-based; and quorum-quenching-designed QSIs have been shown to suppress virulence gene expression and biofilm architecture in preclinical models of Pseudomonas aeruginosa, Staphylococcus aureus, and Vibrio species. QS disruption in the chosen systems increases susceptibility to antibiotics and alters the nature of interactions during infection, with no direct bactericidal effect. Nevertheless, the hurdles to translational progress remain considerable, including signaling redundancy, context-dependent evolution of resistance, pharmacokinetic variability, and the lack of signaling pathways specific to anti-virulence agents. Explaining the therapeutic window, resistance profile, and additive value of QS inhibition, and how to combine it with current antimicrobials, will determine whether such a strategy can play a significant role in the development of future generations of anti-infective agents.\n\nID: 41373806\nTitle: Interkingdom Biofilms Are Affected by Non-Antibiotic Strategies: In Vitro Study in Lubbock Chronic Wound Biofilm Model.\nAbstract: Chronic wound infections associated with resistant polymicrobial biofilms are often refractory to conventional therapies with sustained healing time. This study evaluated the efficacy of non-antibiotic treatments including Methylglyoxal-MGO-Light-Emitting Diode-LED-and Complex Magnetic Fields-CMFs-alone/combined against the biofilms of two polymicrobial mixes (MIX 1, MIX 2) containing S. aureus, P. aeruginosa and C. albicans using the Lubbock chronic wound biofilm model. At 24 h after treatment, the effects were evaluated by (i) CFU/mg reduction, (ii) Confocal Laser Scanning Microscopy-CLSM-and (iii) Scanning Electron Microscopy-SEM. All treatments significantly reduced biofilms in terms of CFU/mg in both mixes versus the controls, 24 h after treatment. MGO showed remarkable activity, especially against P. aeruginosa. In MIX 1, LED/MGO + LED was highly effective against C. albicans. The combinations MGO + LED/MGO + CMFs enhanced the antibiofilm activity compared to each single treatment against S. aureus and P. aeruginosa, in both MIX1/MIX2. CLSM and SEM analysis showed biofilm disaggregation and reduction in cell viability with combined treatments, and Candida hyphal inhibition after CMFs application. In conclusion, the results demonstrate that MGO, alone or combined with LED or CMFs, shows high efficacy against resistant biofilms in the LCWB model 24 h after treatment, and encourage further studies on potential non-antibiotic and eco-friendly strategies as future alternative therapeutic approaches for chronic wound infections.\n\nID: 40323888\nTitle: Cystic Fibrosis Aggregate Biofilm Model to Study Infection-relevant Gene Expression.\nAbstract: Standard pre-clinical testing methods for novel antimicrobial therapeutics used to treat chronic lung infections in people with cystic fibrosis do not reflect the environmental conditions of the hostile lung niche. Current reductionist testing conditions can lead to the progression of compounds along a preclinical pipeline without evidence of their activity under cystic fibrosis lung niche-appropriate conditions. Several approaches used to study traditional antimicrobials may not be suitable for antibiotic alternatives, including anti-virulence therapeutics like anti-quorum sensing agents and siderophore inhibitors. This protocol documents an aggregate biofilm model of Pseudomonas aeruginosa to compare resistance and infection-relevant gene expression in single-species and multi-species cultures (Staphylococcus aureus and Candida albicans), examining colony-forming unit (CFU) reductions and changes in gene expression, using algD as an exemplar. The model was optimized for small, static volumes of bacterial cultures to allow the study of novel compounds in the discovery phase of the drug development pipeline, where compound quantities may be limited. Single-species P. aeruginosa biofilms were formed in Synthetic Cystic Fibrosis Medium 2 (SCFM2) for 24 h before treatment with meropenem at different concentrations (1, 16, and 256 \u00b5g/mL) for a further 24 h. Polymicrobial biofilms were established by growing Staphylococcus aureus and Candida albicans together in SCFM2, then inoculating with P. aeruginosa for an additional 24 h and treating with meropenem. The lack of a direct connection between compound efficacy measures in pre-clinical testing and clinical trial results has cast doubt on the applicability of current laboratory screening tools. This model allows us to understand the impact of relevant factors on P. aeruginosa gene expression, including genes contributing to resistance and virulence, thereby bridging this gap.\n\nID: 40121200\nTitle: Bacterial cell wall-specific nanomedicine for the elimination of Staphylococcus aureus and Pseudomonas aeruginosa through electron-mechanical intervention.\nAbstract: Personalized synergistic antibacterial agents against diverse bacterial strains are receiving increasing attention in combating antimicrobial resistance. However, the current research has been struggling to strike a balance between strain specificity and broad-spectrum bactericidal activity. Here, we propose a bacterial cell wall-specific antibacterial strategy based on an in situ engineered nanocomposite consisting of carbon substrate and decorated TiOx dots, termed TiOx@C. The fiber-like carbon substrate of TiOx@C is able to penetrate the bacterial membrane of Pseudomonas aeruginosa (P. aeruginosa), but not that of Staphylococcus aureus (S. aureus) due to its thicker bacterial wall, thus achieving bacterial wall specificity. Furthermore, a series of experiments demonstrate the specific electro-mechanical co-sterilization effect of TiOx@C. On the one hand, TiOx@C can disrupt the electron transport chain and block the energy supply of S. aureus. On the other hand, TiOx@C capable of destroying the membrane structure of P. aeruginosa could cause severe mechanical damage to P. aeruginosa as well as inducing oxidative stress and protein leakage. In vivo experiments demonstrate the efficacy of TiOx@C in eliminating 97% of bacteria in wounds and promoting wound healing in wound-infected female mice. Overall, such a bacterial cell wall-specific nanomedicine presents a promising strategy for non-antibiotic treatments for bacterial diseases.\n\nID: 34961459\nTitle: Phage-choline Kinase Inhibitor Combination to Control Pseudomonas aeruginosa: A Promising Combo.\nAbstract: Pseudomonas aeruginosa is one of the most prevalent opportunistic pathogens in humans that has thrived and proved to be difficult to control in this \"post-antibiotic era.\" Antibiotic alternatives are necessary for fighting against this resilient bacterium. Even though phages might not be \"the wonder drug\" that solves everything, they still provide a viable option to combat P. aeruginosa and curb the threat it imposes. The combination of antibiotics with phages, however, poses a propitious treatment option for P. aeruginosa. Choline kinase (ChoK) is the enzyme that synthesizes phosphorylcholine subsequently incorporated into lipopolysaccharide located at the outer membrane of gram-negative bacteria. Recently, inhibition of ChoKs has been proposed as a promising antibacterial strategy. Successful docking of Hemicholinium-3, a choline kinase inhibitor, to the model structure of P. aeruginosa ChoK also supports the use of this inhibitor or its derivatives to inhibit the growth of this microorganism. Therefore, the combination of the novel antimicrobial \"choline kinase inhibitors (ChoKIs)\" with a phage cocktail or synthetic phages as a potential treatment for P. aeruginosa infection has been proposed.\n\nID: 34936936\nTitle: Antimicrobial resistance: Prevalence, economic burden, mechanisms of resistance and strategies to overcome.\nAbstract: Antibiotic resistance is a major health concern globally and has been estimated to cause 10 million deaths worldwide by year 2050 if the current trend of inappropriate and excessive use of antibiotics continues. Although, the discovery of antibiotics has saved countless of lives for the past 80 years, increasing levels of bacterial resistance to antibiotics would jeopardize the progress in clinical and agricultural sectors and may cause life-threatening situations even for previously treatable bacterial infections. Antibiotic resistance would increase the levels of poverty of low-middle income countries mostly due to extended hospital stays, higher cost of treatment and untimely deaths that directly affect the total productivity rate. Recent incidences of antibiotic resistance have been gradually increasing globally and this may potentiate horizontal transmission of the resistant gene and have been linked with cross-resistance to other antibiotic families as well. This review summarizes the global burden of antibiotic resistance from the economic viewpoint, highlights the recent incidences of antibiotic resistance mainly related to Escherichia coli, Acinetobacter baumannii, Klebsiella pneumoniae, Salmonella spp. and Staphylococcus aureus, describes the common mechanistic actions of antibiotic resistance and potential strategies to overcome antibiotic resistance.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized.\n  --- END ACTUAL ABSTRACT FOR 42401059 ---\n\n- ERROR: You cited ID: 42394846 for the quote: \"RPST integrates four Raman biomarkers into a Composite Infection Index (CII), enabling rapid and lysis-independent discrimination between susceptible and resistant bacterial populations within ~1 h.\"\n  FACT: Strict Misquote Detected!

However, clinical translation remains hindered by the lack of rapid and quantitative phage susceptibility testing (PST) platforms capable of evaluating host range, infection potency, and effective multiplicity of infection (MOI). Here, we present a ramanome-based phage susceptibility test (RPST), a phenotypic platform that captures infection-induced remodeling of bacterial macromolecular composition to unify these diagnostic requirements within a single workflow. RPST integrates four Raman biomarkers into a Composite Infection Index (CII), enabling rapid and lysis-independent discrimination between susceptible and resistant bacterial populations within ~1\u2009h, with 96.0% categorical concordance (24/25) to plaque assays. As a continuous population-level metric, CII quantifies the proportion of infected cells, allowing quantitative ranking of phage potency against shared hosts. By resolving CII trajectories across the MOI and time, RPST further determines the minimal effective MOI, which is the lowest phage-to-bacterium ratio sustaining self-propagating infection, thereby defining the lower boundary for therapeutic feasibility. Together, these capabilities transform PST from static compatibility assays into a dynamic and quantitative framework that bridges in vitro infectivity assessment and infection dynamics relevant to phage therapy.\n  --- END ACTUAL ABSTRACT FOR 42394846 ---\n\n- ERROR: You cited ID: 42392447 for the quote: \"Notably, CFDC exhibits excellent in vitro activity against contemporary CR-Pseudomonas aeruginosa, most CR-Acinetobacter baumannii harboring blaOXA-23/24/58 genes.\"\n  FACT: Strict Misquote Detected!

However, differences in antibacterial spectra and resistance mechanisms among clinically important Gram-negative bacteria (GNB) between these two agents remain incompletely understood. English-language publications indexed in PubMed (1990-2026), records retrieved from Google Scholar, and the 2018-2024 Antimicrobial Testing Leadership and Surveillance database were extensively reviewed to assess their potential clinical utility. ATM-AVI demonstrates broad activity against KPC-, MBL-, and OXA-48/181-like-producing CRE. However, ATM-AVI non-susceptibility occurs in Escherichia coli and Providencia rettgeri isolates harboring blaCMY, penicillin-binding protein 3 (PBP3) modifications, and porin dysfunction or acrA efflux overexpression. In contrast, CFDC activity is primarily compromised by NDM production, reduced expression of iron transporters, and PBP3 alterations. Significant regional variation in CFDC susceptibility among MBL-producing CRE isolates collected in Asia and North America/Europe has been observed. Based on limited pooled real-world treatment experience, CFDC shows moderate efficacy (73%) for the treatment of infections caused by MBL-producing CRE. Both antibiotics also show potential in vitro activity against ceftazidime-avibactam-resistant, non-carbapenemase-producing CRE. Notably, CFDC exhibits excellent in vitro activity against contemporary CR-Pseudomonas aeruginosa, most CR-Acinetobacter baumannii harboring blaOXA-23/24/58 genes, Elizabethkingia anophelis, Stenotrophomonas maltophilia, Burkholderia cepacia, and Burkholderia pseudomallei. Nevertheless, CFDC heteroresistance is most prevalent among CR-A. baumannii isolates. Continued assessment of clinical treatment experience with these two antibiotics against MBL-producing CRE and important non-fermenting GNB is warranted to accumulate further evidence regarding their therapeutic roles.\n  --- END ACTUAL ABSTRACT FOR 42392447 ---\n\n- ERROR: You cited ID: 4236057 for the quote: \"Aloin demonstrated efficient biofilm-inhibiting capacity at a sub-MIC dose of 4.8 mM, along with/without GEN at 0.002 \u00b5g/\u00b5L (sub-MIC), in an additive manner, determined by the FICI test.\"\n  FACT: Invalid Source ID.

The study of quorum sensing (QS), the bacterial communication system that coordinates important events in an infection, opens a new avenue for treating infections. QS helps in biofilm formation which acts as a physical barrier and alters the microenvironment which traps the molecules or slows down the antibiotic diffusion making them less effective. Since the standard drugs are not very effective against bacteria anymore, demand for the discovery of other alternatives arises. Phytochemicals extracted from commonly used plants like Coleus amboinicus, known to have antimicrobial properties, can be used to develop novel drugs against quorum sensing and hence suppress bacterial infection. Here, we have identified a set of phytochemicals from C. amboinicus whose drug-like properties were predicted using SwissADME and their interactions with the targets involved in QS in Pseudomonas aeruginosa, Vibrio harveyi and Chromobacterium violaceum were studied by performing molecular docking using PyRx software. Beta-amyrin, chrysoeriol and apigenin were found to be the top scored molecules with docking scores of -9.3, -11.3, and -\u200911.1 kcal/mol respectively, and were considered for molecular dynamics simulation using GROMACS software. This was followed by in vitro tests such as Agar well diffusion, Scanning electron microscopy, Pyocyanin assay and Crystal violet assay. Erythromycin was used as the standard drug and as a positive control to validate the results. Based on both in vitro and in silico studies, the phytochemicals from C. amboinicus have the potential to be inhibitors of quorum sensing targets. These findings are preliminary and should be interpreted as hypotheses to be tested experimentally rather than as established mechanisms.\n  --- END ACTUAL ABSTRACT FOR 42334695 ---\n\n- ERROR: You cited ID: 42327744 for the quote: \"Ultimately, a detailed understanding of the RNA modification landscape regulating host-pathogen interactions will help us identify new therapeutic targets.\"\n  FACT: Strict Misquote Detected!

These can be acute or persistent and can exacerbate existing chronic diseases, such as cystic fibrosis, COPD and lung cancer. In this review, we use Pseudomonas aeruginosa as a model organism that demonstrates the molecular complexity of host-pathogen interactions during lower airway infection. Specifically, we focus on RNA modifications and show that they, on the one hand, regulate bacterial fitness and pathogenicity, and on the other control the execution of an effective host innate immune response. Furthermore, we examine the role of epigenetic and epitranscriptomic modifications in the immune dysregulation observed in sepsis, with an emphasis on sepsis-induced lung injury. Innate immune memory - a cellular adaptation mechanism to primary microbial stimulation - results in training or tolerization of host cells towards secondary immune challenges. While fundamentally grounded in epigenetic and metabolic reprogramming, we propose that it can crosstalk with epitranscriptomic regulation. To overcome limitations imposed by animal models when investigating microbe-induced epitranscriptomic dynamics, we highlight physiologically-relevant in vitro tissue models that can complement work performed in vivo. Ultimately, a detailed understanding of the RNA modification landscape regulating host-pathogen interactions will help us identify new therapeutic targets and molecular pathways to better manage the clinical symptoms of bacterial respiratory infections and address the growing challenge of antimicrobial resistance.\n  --- END ACTUAL ABSTRACT FOR 42327744 ---\n\n- ERROR: You cited ID: 42318016 for the quote: \"By understanding how S. aureus is able to survive in the CF lung and why neutrophils are unable to kill this bacterium, it could be possible to identify potential therapeutic targets.\"\n  FACT: Strict Misquote Detected!

S. aureus is able to survive and persist in the CF lung despite robust neutrophilic inflammation. As neutrophils are the immune system's front line of defense against bacteria, the persistent nature of S. aureus infections in CF indicates both a defect in the ability of neutrophils to kill S. aureus and an enhanced ability of the bacteria to survive. S. aureus persistence in the CF lung is driven by both microbial and host, genetic and microenvironmental, factors. There doesn't seem to be one unifying feature that makes S. aureus more virulent in the CF lung as several factors have been proposed to aide its survival. These include increased resistance to antibiotics, the ability to form small colony variants, biofilm formation, co-infection with Pseudomonas aeruginosa, and several virulence factors such as the accessory gene regulatory system, leukocidins, and staphylococcal protein A. A variety of host factors also affect the ability of neutrophils to kill S. aureus in the CF lung. Defects in the function of the cystic fibrosis transmembrane conductance regulator, the genetic cause of CF, affect phagolysosomal killing and lead to increased formation of neutrophil extracellular traps, which are less effective at killing S. aureus. Additionally, data suggest that factors within the CF lung microenvironment also affect neutrophilic killing of S. aureus. However, more research is needed to clearly identify what these environmental factors may be. This review article summarizes the current knowledge on the clinical relevance of S. aureus lung infections in CF, on microbial and host mechanisms promoting S. aureus survival in the CF lung, and on details of neutrophil-S. aureus interactions in CF. By understanding how S. aureus is able to survive in the CF lung and why neutrophils are unable to kill this bacterium, it could be possible to identify potential therapeutic targets to alleviate the consequences of S. aureus respiratory infection in CF.\n  --- END ACTUAL ABSTRACT FOR 42318016 ---\n\n- ERROR: You cited ID: 42306840 for the quote: \"These genetic, structural, and in vivo findings identify ElaABC as potential antivirulence targets in emerging hypervirulent KL49 A. baumannii strains.\"\n  FACT: Strict Misquote Detected!

The nonulosonic acid C8-epimeric 5,7-di-N-acetyllegionaminic acid (8-epi-Leg5,7Ac2) is a component of the K-locus 49 (KL49) capsule of hypervirulent Acinetobacter baumannii, and its epimerization is proposed to be mediated by ElaA, ElaB, and ElaC. We identified a KL49 strain that induces lethal sepsis in mice and found deletion of elaA, elaB, or elaC abolished lethality and markedly reduced capsule production. Crystal structures of ElaB, ElaA, and ElaC revealed conserved N-acetyl recognition underlying CMP-Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Given the slow progress in antibiotic development, phages have emerged as a novel therapeutic strategy against CRAB infections due to their synergistic effects with antibiotics. This study aims to explore phage-antibiotic combination therapy targeting CRAB, thereby providing a theoretical foundation for its clinical translation. Through virulence assessments in Galleria mellonella larvae and mice, CRAB110 was identified as the most virulent strain among 199 clinical CRAB isolates. Transcription analysis revealed that its enhanced pathogenicity may be associated with dysregulated pro-inflammatory responses. Using CRAB110 as the host bacterium, the newly isolated phage, P2, was selected for further study due to its high lytic efficiency and broad host range. The CRAB110 mutant strain CRAB110-2N, treated with P2, exhibited increased drug susceptibility and attenuated virulence compared to the wild-type strain. Both in vitro and in vivo experiments demonstrated that the combination of P2 with antibiotics achieved superior bacterial clearance compared to phage therapy alone. Furthermore, whole-genome analysis of CRAB110-2N revealed a mutation in its ugd. The constructed CRAB110\u0394ugd showed tolerance to P2; the quorum-sensing gene abaI was associated with phage susceptibility, with the CRAB110\u0394abaI strain displaying insensitivity to P2. These findings provide experimental evidence supporting the clinical application of phage-antibiotic combination therapy. This study focused on phage-antibiotic combination therapy targeting carbapenem-resistant Acinetobacter baumannii (CRAB), a priority pathogen designated by the World Health Organization (WHO). A highly virulent strain, CRAB110, was screened from 199 clinical isolates, and a novel, highly lytic phage, P2, was isolated from sewage samples. CRAB110-2N, a mutant strain induced by P2 exposure, displayed increased antibiotic susceptibility and attenuated virulence. Key findings showed that the combination of P2 and meropenem achieved a 99% bacterial clearance rate in vitro and exerted significant synergistic effects in vivo. Genomic analysis identified mutations in the ugd gene, and knockout experiments confirmed its correlation with phage susceptibility. Additionally, the quorum-sensing gene abaI was found to be associated with phage susceptibility in CRAB. Collectively, these results provide critical experimental evidence for the clinical translation of this phage-antibiotic combination therapy.\n  --- END ACTUAL ABSTRACT FOR 42294707 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"The antivirulence efficacies of CT against the co-culture group were weaker than those of in the mono-culture groups.\" (Source: 42409485)\n- \"This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates.\" (Source: 42406312)\n- \"This integrated strategy provides a sustainable and scalable framework for producing high-value aromatic and furanic amines.\" (Source: 42405460)\n- \"Collectively, these findings identify photosynthesis-dependent phycosphere interactions as regulators of bacterial superoxide production, linking biogenic reactive oxygen species to contaminant transformation, chemical-stress resilience, and elemental nutrient turnover.\" (Source: 42402019)\n- \"These findings highlight marked differences in the intrinsic bactericidal strength of commercial products, especially if not applied properly, which may explain variable outcomes observed in routine hospital disinfection practices.\" (Source: 42398007)\n- \"Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections.\" (Source: 42363638)\n- \"Understanding local AMR patterns remains essential for guiding empirical therapy across heterogeneous hospital settings.\" (Source: 42363205)\n- \"Due to the decline in the traditional antibiotic development pipeline, accelerated development of alternative therapeutic strategies is essential.\" (Source: 42353674)\n- \"Although EOs show considerable promise as antimicrobial and anti-virulence agents against P. aeruginosa, their current role should be viewed primarily as adjunctive or alternative strategies rather than as standalone systemic therapies.\" (Source: 42350929)\n- \"The C15 derivative displayed superior activity compared to neamine and synergized with multiple clinical antibiotics against P. aeruginosa.\" (Source: 42341627)\n- \"Genome mining using antiSMASH and BAGEL4 identified gene clusters associated with the synthesis of antifungal compounds, such as hydrogen cyanide, siderophores, cyclic lipopeptides, and ribosomally synthesized peptides.\" (Source: 42341576)\n- \"The advances in alternative treatments, including antimicrobial peptides, bacteriophage therapy, and vaccine development, are also discussed.\" (Source: 42340134)\n- \"By demonstrating that baicalin boosts host immunity through the specific dismantling of the PTP-4/ATLN-1 complex, we highlight a novel therapeutic strategy for combating bacterial infections.\" (Source: 42305438)\n\n\nINSTRUCTION: Study the actual abstracts provided.

We present the first cross-genus atlas of biosynthetic gene clusters (BGCs) in prokaryotic fish pathogens, analyzing 1,855 genomes across 12 families and 14 genera. Using antiSMASH and BiG-SCAPE, we identified 13,626 BGCs encoding NRPS, PKS, RiPPs, terpenes, and siderophores, organized into 2,842 gene cluster families. Strikingly, 1,724 families (61%) lack close MIBiG reference homologs (designated here as MIBiG-distant clusters), representing potentially underexplored enzymatic diversity. Genus-level analyses revealed pronounced specialization: Pseudomonas, Mycobacterium, and Nocardia harbor NRPS/PKS-rich repertoires (>\u20095 BGCs/genome), while Streptococcus and Enterococcus exhibit streamlined RiPP-dominated profiles. Network analysis identified cross-taxon BGC sharing patterns consistent with horizontal gene transfer among aquatic lineages and massive within-genus expansions, with Flavobacterium RiPP families averaging 69 members. Genome-wide correlations linked GC content to BGC density (r\u2009=\u20090.41, p\u2009<\u20090.001), with genus-specific relationships ranging from r\u2009=\u20090.77 (Chryseobacterium) to r\u2009=\u2009-0.84 (Lactococcus), revealing compositional constraints on metabolic evolution. BGC distribution patterns reflected ecological lifestyle and suggested potential roles in iron acquisition, interspecies competition, and host colonization.

Furthermore, the provided literature confirms that non-antibiotic therapeutic modalities, particularly bacteriophage therapy and phytochemical-based anti-virulence approaches, are active areas of research offering potential solutions for multidrug-resistant (MDR) infections.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising global threat of antimicrobial resistance requires a transition toward precision therapeutics that target pathogen-specific mechanisms rather than broad-spectrum viability. *Acinetobacter baumannii* and *Pseudomonas aeruginosa* represent significant challenges due to their sophisticated survival strategies, including biofilm formation, efflux pump regulation, and horizontal gene transfer. The literature demonstrates that these pathogens share common adaptive features, such as iron acquisition systems and quorum-sensing networks, which serve as potential targets for non-antibiotic therapies. For instance, \"PONs (paraoxonases) and other host enzymes can degrade autoinducers\" indicating that host factors actively modulate bacterial communication. Furthermore, \"Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections.\" These alternative strategies, alongside genomic-led discovery of bacteriophages and phytochemical-based inhibitors, offer a framework for circumventing traditional antibiotic resistance. By integrating systems biology and environmental monitoring, these overlooked pathways provide a robust basis for addressing current therapeutic limitations.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Phage-antibiotic combinations demonstrate synergistic clearance rates often exceeding monotherapy efficacy, as confirmed by laboratory models.\n*   Certain phytochemicals, such as coumarins, show specific inhibition bias for the PQS system, offering a mechanism to attenuate pyocyanin production.\n*   The persistence of *S. aureus* in cystic fibrosis airways is facilitated by co-infection with *P. aeruginosa*, highlighting the importance of polymicrobial interactions.\n*   Bacteriophage survival in wastewater is influenced by environmental temperature and chemical stressors, identifying them as potential vectors for ARG dissemination.\n*   Targeting the PTP-4/ATLN-1 complex via small molecules like baicalin provides a \"dual-hit\" mechanism to unleash host innate immune responses.\n*   The use of host-defense peptides often involves structural determinants, such as C-terminal amidation, which are essential for membrane-disruptive activity.\n*   Metabolic dysregulation in *A. baumannii*, specifically targeting cysteine homeostasis, induces synthetic lethality in host infection models.\n*   Genomic mining reveals a vast, largely underexplored enzymatic landscape in fish-pathogenic *Pseudomonas* that can be repurposed for natural product discovery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Antimicrobial peptides (AMPs) have emerged as promising therapeutic candidates due to their broad-spectrum activity and low propensity for resistance development. However, conventional discovery approaches remain time-consuming and inefficient for large-scale screening. In this study, we developed an integrated prediction framework that combines deep learning with classical machine learning methods to enable rapid and accurate identification of AMPs. The model was applied to screen over 250,000 artificially generated peptide sequences. Candidate peptides were selected based on physicochemical descriptors and activity-associated features, followed by solid-phase synthesis and minimum inhibitory concentration assays against Pseudomonas aeruginosa. Mechanistic investigations were conducted using scanning electron microscopy to visualize membrane damage, molecular dynamics simulations to probe peptide-membrane interactions, and transcriptomic profiling to assess bacterial stress responses and metabolic pathway alterations. Ten promising antibacterial candidates were successfully identified and experimentally validated. All selected peptides exhibited measurable activity against P. aeruginosa, with several showing potent inhibitory effects. Microscopic and simulation analyses confirmed that the peptides exert their antibacterial effects primarily through membrane disruption. Transcriptomic data further revealed that these peptides interfere with key metabolic pathways and activate bacterial stress response systems. Our findings demonstrate that the integrated deep learning-machine learning pipeline offers an efficient and reliable approach for large-scale AMP discovery. The mechanistic insights gained from this study not only validate the predicted candidates but also provide a foundation for rational optimization of peptide-based therapeutics. This comprehensive strategy holds promise for accelerating the development of next-generation alternatives to conventional antibiotics."

This review examines how host-derived factors modulate QS-linked virulence in enteric pathogens, Pseudomonas aeruginosa and Staphylococcus aureus. Across these systems, host control operates through three recurring modes: activation or signal mimicry, enzymatic signal degradation, and extracellular sequestration or receptor-level interference. Catecholamines and related metabolites can feed into bacterial sensory pathways and promote virulence signaling; PONs (paraoxonases) and other host enzymes can degrade autoinducers; and lipoproteins, immune mediators, and epithelial surveillance systems can intercept or reinterpret quorum signals. Together, these data support the view that the host is an active signal-processing environment that reshapes colonization, persistence, and tissue damage, and they point to host-inspired anti-virulence strategies that target signaling rather than viability."

This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates. We performed large-scale comparative genomic analysis of 340 virulent Acinetobacter bacteriophages, integrating phylogenetic reconstruction, pangenome analysis, CRISPR spacer-based host interaction mapping, Anti-CRISPR protein identification, and systematic antimicrobial resistance (AMR) gene screening. Genome sizes spanned a nearly 20-fold range, with a significant negative correlation between genome size and GC content (R\u00b2 = 0.139, \u03c1 = -0.630). Phylogenetic analysis revealed extensive divergence across multiple lineages with no dominant clade. Pangenome analysis identified 20,982 unique protein families, of which 76.2% were cloud genes, confirming a highly open genome architecture. CRISPR spacer matching yielded 1,480 high-confidence matches across 100 phage genomes, providing molecular evidence of broad historical infectivity. Anti-CRISPR profiling identified Acinetobacter phage XC1 as an exceptional therapeutic candidate harboring 55 predicted Anti-CRISPR proteins with canonical regulatory locus architecture. AMR screening identified 21 distinct AMR gene homologs (Loose RGI hits, 22.5 to 47.1% amino acid identity) distributed heterogeneously across the dataset, confirming abundant therapeutically clean candidates while flagging a subset warranting further scrutiny before therapeutic exclusion. These findings provide a multi-criteria genomic framework for rational phage candidate prioritization against multidrug-resistant Acinetobacter infections, with direct implications for evidence-based phage therapy development."

In this study, Streptomyces sp. KJ7TB2 was isolated from the Indian Sundarbans. An ethyl acetate extract was subjected for GC-MS profiling. The mechanisms of antibacterial and antibiofilm action were also explored. In-silico molecular docking and dynamics simulation analyses were performed. The GC-MS analysis of the extract revealed 14 distinct bioactive secondary metabolites. The extract exhibited potent MIC values of 250\u2009\u03bcg/mL and 125\u2009\u03bcg/mL against Escherichia coli MTCC 1195 and Pseudomonas aeruginosa ATCC 27853. Antibiofilm investigation further revealed inhibition of biofilm formation in both pathogens especially in E. coli MTCC 1195, likely by disrupting initial surface adhesion and exopolysaccharide synthesis. Also, the extract inhibited swarming motility, suggesting interference with flagella-driven motility and quorum sensing. The brine shrimp lethality assay confirmed a favorable safety profile, recording limited mortality (36.84% at 2\u00d7MIC over 24\u2009h). In-silico molecular docking and dynamics simulation analyses exhibited robust affinity for two key biofilm-associated proteins, exhibiting significant binding energy (\u0394G). The study highlights Streptomyces sp. KJ7TB2 as a potential source for the discovery of safe, potent therapeutics. Exploring a Mangrove-derived microbe to fight against drug-resistant germs. Antibiotic resistance is a serious global health risk. Many antibiotics do not work as well as before. Because of this, bacterial infections are becoming harder to treat. Scientists are looking for new medicines from natural sources. In this study, we found a rare, helpful microbe from the mangrove forests of the Indian Sundarbans. These forests contain many useful microorganisms. A rare bacteria called Streptomyces sp. KJ7TB2 was collected and grown in the laboratory. After cultivation of the bacteria and collecting its extract, chemical studies found 14 useful compounds. The extract showed strong activity against harmful bacteria. It also stopped the bacteria from building protective walls around themselves. It blocks the signals of the bacteria use to talk with each other. Computational studies also supported these results. Safety tests showed very low toxicity of the extract. This means it may be safe for future studies. Overall, this study suggests that Streptomyces sp. KJ7TB2 could be a useful natural source for new treatments against drug-resistant bacterial infections."

Gram-negative microbes such as carbapenem-resistant Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae are becoming more resistant than ever. Traditional methods of treatment using antibiotics are ineffective because of the presence of several envelope layers, active efflux pumps, and biofilm production. In contrast, bacteriolytic therapy can exacerbate host immunopathology owing to systemic endotoxin release. Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment; however, clinical use remains hindered by their low stability, high binding to serum proteins, and narrow therapeutic index. In this review, we will discuss the use of biomaterial platforms in the design of peptide-based therapeutics to not only increase their efficacy by reducing peptide clearance but also optimize the immunological environment in which these peptides operate. We will discuss the role of various characteristics, such as surface chemistry, mechanical stiffness, and protein corona, in influencing macrophage polarization and downstream signaling pathways. In addition, we point out a significant limitation within this area of research: many preclinical studies continue to use minimum inhibitory concentration and hemolysis values, which fail to account for the host-directed effects that make these approaches significant. For future progress in this realm, new endpoints are required, along with more clinically relevant animal models and a true incorporation of peptide design into biomaterials engineering."

Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation. Studies demonstrate robust efficacy of probiotics against clinically challenging pathogens, including methicillin-resistant Staphylococcus aureus, multidrug-resistant Pseudomonas aeruginosa, Clostridioides difficile, Helicobacter pylori, and pathogenic Escherichia coli. Postbiotics, particularly cell-free supernatants and purified bacteriocins, offer standardized, shelf-life probiotic products. Notably, synergistic combinations with conventional antibiotics, phytochemicals, or bacteriophages enhance antimicrobial activity while enabling dose-reduction strategies to mitigate the development of resistance. However, compelling preclinical evidence, clinical translation remains constrained by the imperative for strain-specific characterization, methodologically robust randomized controlled trials, and comprehensive safety validation. This study critically mentions current mechanisms underlying Lactobacillus-mediated anti-biofilm strategies and identifies priority research essential to accelerating clinical application."

Alternative non-canonical structures have also been proposed, in which a duplication is formed by a single IS element whose two ends join two distant chromosomal loci. However, the prevalence of such non-canonical structures and their role in bacterial adaptive evolution remain unclear. Here we developed AmpliFinder, a computational tool that uses short-read sequencing data to systematically identify pairs of IS-chromosome junctions that correspond to the two ends of the same IS element yet map to distant genomic loci flanking amplified regions. Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification. We validated the inferred architectures using ultra-long-read sequencing and propose a model for non-canonical amplification formation supported by the observation of nested intermediate structures. Quantifying enrichment for antibiotic-resistance genes in amplicons, we find that non-canonical amplifications more effectively and narrowly amplify genes under selection. These results highlight the role of non-canonical IS-based amplifications in the adaptive evolution of bacteria."

Although vaccination reduces infection rates and mortality, the vulnerable post-vaccination immunity gap can still result in infection and vaccine failure. In addition, effective vaccines are unavailable for many clinically important bacterial pathogens. Here, we report a pulmonary mRNA-lipid nanoparticle (mRNA-LNP) vaccine incorporating an ionizable lipid engineered for localized high-level expression, which elicits both rapid and durable protection against bacterial lung infections in female mice, effectively bridging this critical window of vulnerability. Intratracheal delivery of mRNA-LNP rapidly primes lung neutrophils and macrophages into a transcriptionally pre-activated state, enhancing their phagocytic activity and enabling rapid, antigen-independent bacterial clearance during the early post-vaccination period (approximately 1-7 days). Subsequently, vaccination induces potent antigen-specific adaptive responses, conferring sustained protection against both laboratory and clinical drug-resistant Pseudomonas aeruginosa strains. Single-cell transcriptomics and immune profiling reveal coordinated activation of innate and adaptive immune programs. This dual-phase immune response exemplifies a paradigm-shifting vaccine design that integrates innate and adaptive immunity to confer both immediate and long-term protection. Our findings establish a mechanistic basis for rapid antibacterial defense and highlight pulmonary mRNA-LNP vaccination as a promising strategy for combating respiratory infections."

Tetrasodium EDTA (tEDTA) is one of the new antimicrobial compounds that have been shown to have good antibacterial and antibiofilm efficacy against P. aeruginosa. Due to the diversity and highly drug-tolerant nature of P. aeruginosa biofilms in different infection environments, it is important to carry out pre-clinical testing of new antibiofilm agents against this pathogen in media and models that accurately mimic diverse infection environments. In this study, we used different high-validity media and biofilm models that mimic chronic wounds, endotracheal tubes and cystic fibrosis lung infections to assess the efficacy of tEDTA against P. aeruginosa biofilms. We report that different infection environments influence the susceptibility of both planktonic and biofilm forms of P. aeruginosa to tEDTA. The highest tolerance to tEDTA was observed in the media and biofilm model that mimics the endotracheal tube environment. In conclusion, we show that although different infection environments influence the efficacy of tEDTA against P. aeruginosa biofilms, it has good potential for use as an alternative antimicrobial in treating P. aeruginosa-associated biofilm infections."

We determined how two dormancy pathways, ribosome hibernation and the stringent response, contribute to the survival and antibiotic tolerance of Pseudomonas aeruginosa biofilms. Analyses of whole biofilms and single cells showed that these pathways have differing effects on biofilm cell physiology. Ribosome hibernation, mediated by hibernation promoting factor (HPF), is essential for optimal survival and resuscitation of starved biofilm cells. In the absence of HPF, starved cells progressively lose ribosome integrity. However, loss of HPF does not increase the sensitivity of P. aeruginosa biofilm cells to ciprofloxacin or tobramycin. In contrast, the stringent response, mediated by RelA and SpoT, is not required for viability or ribosome integrity in starved biofilm cells, but does affect biofilm antibiotic tolerance. In a plant model of biofilm infection, disruption of either ribosome hibernation or the stringent response reduced bacterial virulence. The results show that ribosome hibernation preserves ribosomal integrity necessary for recovery from starvation and for pathogenesis, while the stringent response is required for growth arrest, antibiotic tolerance, and pathogenesis. These two ribosome-mediated pathways play distinct yet complementary roles in regulating dormancy and persistence of P. aeruginosa biofilms."

Until now no licensed PA vaccine exists and multi-dose schedules are difficult to complete in emergency settings, thus a single-dose, dual-indication vaccine that provides rapid and durable protection is urgently needed. Here, we engineered and characterized a lumazine synthase (LS) nanoparticle vaccine (rePO-TTFC@LS) that co-displays a PA antigen (rePO; PcrV-OprI fusion) and tetanus toxin fragment C (TTFC). In BALB/c mice, rePO-TTFC@LS enhanced antigen uptake and dendritic-cell activation relative to soluble antigens. After a single intramuscular immunization, rePO-TTFC@LS elicited rapid, high anti-rePO and anti-TTFC IgG responses together with increased IFN-\u03b3/IL-4/IL-17A-secreting splenocytes. Vaccination reduced lung bacterial burden and pulmonary IL-1\u03b2/IL-6 and improved survival and clinical outcomes in an acute PA pneumonia model, which provided complete protection against lethal tetanus toxin challenge, and decreased PA colonization with improved survival in a femoral fracture-implant co-infection model. Elevated antibody titers and dual protection persisted to 28 weeks after one dose, and biosafety assessments showed no meaningful hemolysis or cytotoxicity and no abnormalities in hematology/serum biochemistry or multiorgan histopathology. Collectively, these results support rePO-TTFC@LS as a single-dose, durable dual-indication nanoparticle vaccine and highlight a modular strategy for combination vaccines suited to mixed-exposure emergency scenarios."

The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized."

The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM. Targeting MexL may serve as a novel anti-virulence strategy by suppressing pyocyanin production and attenuating pathogenicity of P. aeruginosa. This study aimed to identify potential inhibitors of MexL using in silico approaches to disrupt its regulatory function and reduce pyocyanin synthesis. The findings suggest that the selected compounds could serve as effective inhibitors of MexL, offering a promising strategy to suppress pyocyanin biosynthesis and reduce P. aeruginosa virulence. For this purpose, molecular docking was conducted between the binding pocket of the MexL protein and compounds selected based on pharmacokinetic properties from the FooDB, NPASS, and LOTUS databases. Furthermore, molecular dynamics simulations were performed on the selected MexL-ligand complexes to evaluate the stability of the protein-ligand complex within a simulated solvated environment under defined conditions. The virtual screening by molecular docking identified four top-scoring ligands FDB000380, LTS0012415, and NPC253096 and ZINC14780782 with binding energies of -8.6, -7.5, -7.1, and -8.8\u00a0kcal/mol respectively, showing strong affinities toward the MexL binding pocket.

This study synthesized and characterized artemisinin-loaded micelle/liposome nanoparticles (Art/PEG400-OA NPs) and evaluated their antibacterial, antibiofilm, and anticancer efficacy.

While many studies have sampled mutant populations after prolonged incubation on roots to identify bacterial genes that enable long-term colonization, the molecular mechanisms governing the early stages of root attachment remain less understood. Here, we developed an in vitro root culture system that enables controlled and scalable investigation of bacterial attachment to root tissue. We used this platform to perform a genome-wide screen for root attachment determinants in the plant-associated bacterium Pseudomonas protegens Pf-5. Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment. Mutations that disrupt gacS or gacA cause severe root attachment defects despite having no effect on abiotic surface attachment in standard biofilm assays. Mutation of flagellar assembly genes enhances root attachment by mimicking surface contact and activating the gac system. In parallel, chemical cues released by roots stimulate surface attachment in a gac-dependent manner. By integrating these signals, the gac system activates cyclic-di-GMP-mediated attachment programs that drive the transition from planktonic to sessile behavior required for root association. We build on this model to show that manipulating flagellar surface-sensing sustains the attachment of Pf-5 in the presence of a synthetic bacterial community, suggesting a strategy to improve the attachment of beneficial microbes on crops. These findings establish a mechanistic framework linking surface sensing, global regulation, and root attachment in a beneficial rhizobacterium.IMPORTANCEPlant roots are covered with diverse microbes that strongly influence plant health. Growing in association with roots has many benefits, but how bacteria attach to root tissue remains poorly understood. We developed a system to study how the plant-associated bacterium Pseudomonas protegens Pf-5 attaches to roots. We found that physical contact with the root surface and chemical cues released by roots both enhance attachment to roots. A sensory system called gacSA is responsible for integrating physical and chemical cues to activate a root attachment program. Variant bacteria that prematurely activate the gac system attach more effectively even in the presence of other bacteria on roots, suggesting that the root attachment pathway we characterized could serve as a strategy to use beneficial bacteria in agriculture."

These mutations lead to elevated extracellular pyruvate, which dampens host inflammatory responses and favors bacterial persistence. Pyruvate exerts multiple roles: scavenges reactive oxygen species such as H2O2, suppresses host immune activation both in airway epithelial cells and macrophages, and increases bacterial survival during phagocytosis. This metabolic crosstalk promotes bacterial persistence while reducing epithelial and macrophage inflammatory responses.

The in vitro antimicrobial properties of STF were analyzed using checkerboard assays to determine the fractional inhibitory concentration (FIC) index. The cytotoxicity of STF was determined using the MTT viability assay using L929 fibroblasts. The in vivo efficacy of STF was assessed using a rat excisional wound model, and wound closure rates were measured at 14\u2009days post-infection. STF showed an additive interaction in the in vitro model (FIC index: 0.717-0.936) and possessed low cytotoxicity (IC50: 705.4\u2009\u00b5g/mL) compared to the individual compounds. In the in vivo model, the group treated with STF showed significantly faster wound healing and decreased inflammation compared to all other groups, including the silver sulfadiazine group. The combination of snail mucus in STF is a highly effective remedy for infected wounds, providing complementary benefits in vivo by coupling antimicrobial activity with pro-regenerative functions, and demonstrates superiority over silver sulfadiazine."

Here, we analyzed the prevalence and genotype distribution of VFGs in P. aeruginosa isolated from Nanyang Central Hospital (NYCH), China, along with their antibiotic susceptibility profiles. The study involved 79 multidrug-resistant (MDR) and 96 non-MDR (nMDR) strains and the following 11 key VFGs (nan1, pilA, aprA, phzS, plcH, toxA, lasB, exoS, exoU, exoT, exoY). Antibiogram profiling showed near-universal resistance to at least one antibiotic class. MDR strains exhibited 23 distinct antibiotic resistance patterns, compared with 13 patterns in nMDR strains. A moderate negative correlation was observed between \u03b2-lactams/\u03b2-lactamase inhibitors and fluoroquinolone resistance. Moreover, statistical analysis revealed that the phzS gene displayed the most significant prevalence difference between MDR and nMDR subgroups (P < 0.001). Finally, 28 distinct genotypes were identified in nMDR isolates, and 26 genotypes appeared in MDR strains. There was a statistically significant correlation found between the presence of genotype XX (r = 0.481, P < 0.001) and genotype XXVIII (r = -0.320, P < 0.001) in two subgroups. Collectively, our findings provide data support for understanding the pathogenic mechanism of local P. aeruginosa, and are of great significance for guiding clinical anti-infection treatment and infection control.IMPORTANCEPseudomonas aeruginosa is an opportunistic pathogen notorious for causing difficult-to-treat infections, particularly among hospitalized patients in resource-limited healthcare settings. This study analyzed clinical isolates from a major hospital in China to investigate the prevalence and genotypic distribution of virulence factor genes (VFGs) and antibiotic susceptibility profiles of P. aeruginosa. Our results showed that multidrug-resistant (MDR) strains displayed more complex and diverse resistance profiles than non-MDR (nMDR) strains. Both MDR and nMDR isolates exhibited high genotypic diversity. Notably, a statistically significant association was observed between genotype XX and genotype XXVIII across the two subgroups. These findings elucidate the molecular basis underlying the variable treatment difficulty of P. aeruginosa infections and offer valuable insights for guiding empirical antibiotic selection. Characterizing local bacterial features, including antibiotic susceptibility profiles and the distribution of clinically relevant virulence factors, may improve understanding of regional resistance trends and support antimicrobial stewardship and infection control efforts."

This study characterized the bacterial profile of endotracheal aspirate samples from a PICU in Sulaimani, confirmed A. baumannii identification using blaOXA-51 PCR, assessed antimicrobial resistance patterns, and determined genotypic diversity using ERIC-PCR. From August 2023 to March 2025, 100 consecutive Gram-negative isolates were recovered from mechanically ventilated pediatric patients. VITEK2 was used for identification and susceptibility testing. XDR Acinetobacter isolates underwent molecular confirmation via blaOXA-51 PCR, and confirmed isolates were genotyped using ERIC-PCR with UPGMA analysis. Among the 100 total isolates, A. baumannii accounted for 21 isolates alongside Pseudomonas aeruginosa (n\u2009=\u200933) and Klebsiella pneumoniae (n\u2009=\u200920). Given its clinical significance, A. baumannii was selected for further molecular characterization.

The literature confirms that these pathogens utilize shared resistance and virulence mechanisms\u2014such as biofilm formation, efflux pumps, and specific regulatory pathways\u2014which are being targeted by non-traditional therapies, including bacteriophages and bioactive compounds, to mitigate the global antimicrobial resistance (AMR) crisis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising threat of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* stems from their capacity to form recalcitrant biofilms and utilize sophisticated regulatory networks to escape antibiotic action. Research indicates that both pathogens, often classified as high-priority, share vulnerabilities that allow for the potential application of cross-species therapeutic strategies. Non-antibiotic solutions are critical as traditional antibiotics face decreased efficacy due to envelope layers and efflux systems. Innovations in bacteriophage therapy provide a targeted approach to bypass conventional resistance. Furthermore, the development of nanoparticle platforms and peptides targeting specific proteostasis mechanisms offers a path toward eradicating persistent, multidrug-resistant (MDR) strains. The evidence supports a transition toward multifaceted strategies that integrate host-directed immune modulation with targeted microbial interference.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Transcriptional Regulation:** The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM.\n*   **Proteostasis Vulnerability:** FtsH is the key protective mechanism, as only \u0394ftsH drives a 16-fold sensitization, identifying it as the bottleneck for survival under peptoid stress.\n*   **Immunometabolism:** Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization.\n*   **Host-Directed Defense:** Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment.\n*   **Probiotic Synergy:** Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation.\n*   **Horizontal Gene Transfer:** In this study, we revealed that exposure to five types of OPEs (0.1-1000 \u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater.\n*   **Biocontrol Potential:** The endophytes demonstrated significant antagonistic activity, inhibiting the growth of fungal mycelia.\n*   **Genomic Adaptation:** Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification.\n*   **Signaling Integration:** Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment.\n*   **Evolving Therapeutics:** This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This study focused on endophytic microbiomes of six banana (Musa spp.) cultivars grown under shared environmental conditions to determine how genotype influences microbial diversity and structure. We used deep amplicon sequencing to investigate the endophytic microbiomes from above- and below-ground tissues of wild diploid cultivars Musa balbisiana, M. balbisiana \"Thai Black\", and M. textilis, and domesticated triploid cultivars Dwarf Cavendish, Williams Hybrid, and hybrid FHIA-25, grown in sympatry. Across all samples, dominant genera included Pseudomonas, Acinetobacter, Enterobacter, Devosia, and Rhizobium, while 27.4% of ASVs were unclassified. Although many core taxa were shared, each cultivar and tissue harbored distinct low-abundance microbial taxa. Beta diversity analyses revealed that banana cultivar explained a small but significant proportion of community variation (Bray-Curtis R 2\u202f=\u202f2.7%, p\u202f=\u202f0.002; Weighted UniFrac R 2\u202f=\u202f2.9%, p\u202f=\u202f0.005), whereas tissue type and domestication contributed less to overall variation. PICRUSt2 predicted functional differences among endophytic communities across banana cultivars, with 49 pathways differing between wild and domesticated plants, including enrichment of lipid metabolism, biotin biosynthesis, and aromatic compound degradation in domesticated cultivars. However, because domestication status and ploidy differed among the selected cultivars, these effects could not be fully separated in the current study. Together, these results indicate that banana genotype influences endophytic microbiome composition and predicted function, although host genotype accounted for only a modest proportion of the observed variation, highlighting the importance of additional ecological and environmental factors in shaping plant-associated microbial communities.\n\nID: 42422742\nTitle: Antimicrobial potential of bacteria isolated from sediment and Avicennia germinans collected from the mangroves of Vichayal (Northern Peru, Piura) and their application in the preservation of Scomber japonicus peruanus.\nAbstract: Mangrove ecosystems in Peru represent largely unexplored reservoirs of bacterial diversity with considerable biotechnological potential. This study evaluated the antimicrobial activity of bacteria isolated from sediments and endophytic tissues of Avicennia germinans from the Vichayal mangroves (Piura, northern Peru) using the volatile organic compounds test (VOCt), the Over Plate Test (OpT), minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) against Gram-positive pathogenic bacteria (Enterococcus faecalis, Staphylococcus epidermidis, S. aureus, and Listeria monocytogenes), Gram-negative pathogenic bacteria (Escherichia coli and Salmonella enterica sv. typhimurium), and two Candida species (Candida albicans and C. tropicalis), as well as their application in the preservation of Scomber japonicus fillets, prior to biosafety testing and phylogenetic analysis. A total of 34 isolates were obtained - 21 from sediments and 13 from A. germinans. Based on the VOCt and OpT assays, seven strains were identified by 16S rDNA sequencing as Bacillus albus ZB3, Priestia flexa (ZA5 and ZA9), Enterococcus faecalis ZB5, Pseudomonas monteilii (ZA1 and ZAAgR1), and Acinetobacter junii ZB7, yielding cell-free extracts containing bioactive substances (42.95-47.44 mg/mL). MIC results showed that 85.7% of the strains inhibited S. aureus ATCC25923 and E. coli O157:H7, while MBC activity was confirmed for ZA1, ZB3, and ZAAgR1 at extract concentrations \u226510%. The biosafety profile revealed gamma-hemolysis and the absence of DNase activity across all strains, consistent with a non-virulent phenotype; however, widespread antibiotic resistance was detected. Application of cell-free extracts to mackerel fillets demonstrated that B. albus ZB3 reduced aerobic mesophile counts (6.19 vs. 6.46 log\u2081\u2080 CFU/g) at ambient temperature (27 \u00b1 2 \u00b0C, 2 days), while P. monteilii ZAAgR1 was more effective under refrigeration (6.19 vs. 6.36 log\u2081\u2080 CFU/g, 7 \u00b1 2 \u00b0C, 7 days). These findings identify bacteria associated with the Vichayal mangroves as promising candidates for fishery product preservation, pending comprehensive genomic and safety characterization.\n\nID: 42422065\nTitle: Machine learning-driven discovery of antimicrobial peptides against Pseudomonas aeruginosa.\nAbstract: Antibiotic resistance has become a global health crisis, driving the urgent need for novel antibacterial strategies. Antimicrobial peptides (AMPs) have emerged as promising therapeutic candidates due to their broad-spectrum activity and low propensity for resistance development. However, conventional discovery approaches remain time-consuming and inefficient for large-scale screening. In this study, we developed an integrated prediction framework that combines deep learning with classical machine learning methods to enable rapid and accurate identification of AMPs. The model was applied to screen over 250,000 artificially generated peptide sequences. Candidate peptides were selected based on physicochemical descriptors and activity-associated features, followed by solid-phase synthesis and minimum inhibitory concentration assays against Pseudomonas aeruginosa. Mechanistic investigations were conducted using scanning electron microscopy to visualize membrane damage, molecular dynamics simulations to probe peptide-membrane interactions, and transcriptomic profiling to assess bacterial stress responses and metabolic pathway alterations. Ten promising antibacterial candidates were successfully identified and experimentally validated. All selected peptides exhibited measurable activity against P. aeruginosa, with several showing potent inhibitory effects. Microscopic and simulation analyses confirmed that the peptides exert their antibacterial effects primarily through membrane disruption. Transcriptomic data further revealed that these peptides interfere with key metabolic pathways and activate bacterial stress response systems. Our findings demonstrate that the integrated deep learning-machine learning pipeline offers an efficient and reliable approach for large-scale AMP discovery. The mechanistic insights gained from this study not only validate the predicted candidates but also provide a foundation for rational optimization of peptide-based therapeutics. This comprehensive strategy holds promise for accelerating the development of next-generation alternatives to conventional antibiotics.\n\nID: 42420824\nTitle: Phenotypic and molecular characterization of carbapenem resistance among clinical isolates of Pseudomonas aeruginosa and Acinetobacter baumannii.\nAbstract: Carbapenem-resistant Pseudomonas aeruginosa (CRPA) and Acinetobacter baumannii (CRAB) were listed on the WHO bacterial priority pathogens list in 2017. These gram-negative bacteria often cause healthcare-associated infections (HAIs), which pose an increasing threat to public health. This study aimed to isolate and identify CRPAs and CRABs from a tertiary care hospital in central Nepal and characterize carbapenem resistance genes at the molecular level. A total of 59 isolates, including 27 Pseudomonas aeruginosa and 32 Acinetobacter baumannii, were collected from different clinical samples from April 2021 to December 2022. Antibiotic susceptibility was determined via the Kirby disc diffusion method. The modified carbapenem inactivation method (mCIM) was used for phenotypic confirmation of carbapenem resistance. Conventional polymerase chain reaction (PCR) was used to detect carbapenem resistance genes. Among the 59 isolates, 76.3% were multidrug resistant (MDR), 63.0% were extended-spectrum beta-lactamase (ESBL), and 62.7% were carbapenem resistant. Among the carbapenem-resistant isolates (n\u2009=\u200937), 75.7% of metallo-beta-lactamase (MBL) producers and 70.3% carried at least one carbapenem resistance gene. The blaCTX-M gene was predominant among the ESBL-positive isolates, present in 58.8% of the P. aeruginosa isolates and 87.5% of the A. baumannii isolates, whereas 29% of both isolates harbored the blaTEM gene. Among the CR-PA isolates, 58.3% carried blaVIM-2, 16.7% carried blaNDM-1, and 8.33% carried blaOXA-23. Among the CR-AB isolates, 56% harbored blaOXA-23, 32% carried blaNDM-1, 16% had both blaNDM-1 and blaOXA-23, and 8% contained both blaOXA-58 and blaOXA-23. This study highlights a significant burden of MDR and carbapenem-resistant P. aeruginosa and A. baumannii, with the co-occurrence of carbapenem resistance genes, in a clinical setting in Nepal. Our findings suggest that active surveillance of antibiotic resistance in pathogens could inform clinicians and healthcare providers about the treatment of infections.\n\nID: 42420271\nTitle: Immune protection and persistence in Pseudomonas aeruginosa infections by pyruvate cross-feeding.\nAbstract: Chronic infections by Pseudomonas aeruginosa in people with cystic fibrosis are characterized by persistent inflammation and oxidative stress, yet the mechanisms enabling bacterial persistence are not fully understood. Here, we identify a persistence mechanism mediated by pyruvate secretion resulting from mutations in the pyruvate dehydrogenase complex in clinical isolates of P. aeruginosa, with putative analogous mutations also identified in Staphylococcus aureus, Haemophilus influenzae and Stenotrophomonas maltophilia. These mutations lead to elevated extracellular pyruvate, which dampens host inflammatory responses and favors bacterial persistence. Pyruvate exerts multiple roles: scavenges reactive oxygen species such as H2O2, suppresses host immune activation both in airway epithelial cells and macrophages, and increases bacterial survival during phagocytosis. This metabolic crosstalk promotes bacterial persistence while reducing epithelial and macrophage inflammatory responses. Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization. This work highlights the broader role of secreted metabolites in host-pathogen interactions and suggests new strategies targeting metabolic pathways to manage chronic infections.\n\nID: 42419871\nTitle: Ambient temperature variations and antimicrobial resistance: a multicountry analysis of non-linear relationships and temperature thresholds.\nAbstract: Antimicrobial resistance (AMR) is an escalating global health crisis being worsened by climate change. Studies of temperature-AMR associations remain limited by geographic scope, time frames and linear approaches. We aimed to identify temperature thresholds where AMR dynamics shift across pathogen-drug combinations, periods and socioeconomic contexts. We analysed data from 56 countries and territories over 24 years (1999-2022), focusing on six WHO-designated 'critical' antibiotic-resistant pathogens. Using segmented regression models with mean ambient temperature as the primary independent variable, we divided the study period into three intervals (1999-2006, 2007-2014, 2015-2022)\u2009and incorporated 16 socioeconomic and environmental covariates. Model robustness was validated through bootstrap cross-validation with 1000 resamples. We identified distinct temperature association thresholds for each pathogen-drug combination (5.7\u00b0C-18.4\u00b0C). Below these thresholds, resistance rates consistently decreased with rising temperatures; above thresholds, responses varied by phenotype and time period. For third-generation cephalosporin-resistant Escherichia coli, each 1\u00b0C rise above 16.5\u00b0C corresponded to a 0.46% increase (95%\u2009CI 0.28% to 0.65%; p<0.001) during 1999-2006, a 0.11% decrease (95%\u2009CI -0.17% to -0.06%; p<0.001) during 2007-2014 and a 0.18% increase (95%\u2009CI 0.11% to 0.25%; p<0.001) during 2015-2022. The Corruption Perception Index showed consistent negative associations with resistance rates, particularly for carbapenem-resistant Acinetobacter baumannii (\u03b2=-1.40, p<0.001). Phenotype-specific temperature association thresholds provide descriptive, hypothesis-generating reference points for understanding how AMR burden varies along the global temperature gradient. The observed temporal heterogeneity suggests complex patterns requiring long-term monitoring and climate-adaptive AMR control strategies considering both phenotype-specific temperature sensitivities and socioeconomic contexts.\n\nID: 42419644\nTitle: Carbapenem resistance dynamics in clinical Pseudomonas aeruginosa isolates from a tertiary hospital in Valpara\u00edso, Chile, 2019-2024.\nAbstract: Pseudomonas aeruginosa is a major cause of healthcare-associated infections and a World Health Organization priority pathogen because of its marked ability to develop resistance to last-line antibiotics. Carbapenem resistance may arise through chromosomal mutations, acquisition of resistance genes, and clonal dissemination under sustained antimicrobial pressure. To investigate the temporal dynamics of carbapenem resistance in clinical P. aeruginosa isolates from a tertiary-care hospital in Valpara\u00edso, Chile, and to assess their association with antimicrobial consumption. Forty-five clinical isolates recovered between 2019-2024 were analyzed. Antimicrobial susceptibility testing, phenotypic and molecular carbapenemase detection, motility and biofilm assays, and whole-genome sequencing were performed. Sequence types, resistome, virulome, and chromosomal mutations associated with resistance were characterized. Antimicrobial consumption data from the local stewardship programme were evaluated using temporal trend and cross-correlation analyses. Carbapenem non-susceptibility was frequent, and extensively drug-resistant isolates predominated during the pandemic and post-pandemic periods. Resistance was mainly associated with non-carbapenemase-producing isolates and was linked to mutations in oprD, regulators of the MexAB-OprM efflux system, and ampC-related pathways, together with intrinsic OXA-50-like-\u03b2-lactamases. The blaVIM-2 gene was identified in ST408, ST815, and ST253. Temporal clonal turnover was observed, with ST309 emerging as the dominant lineage in 2023-2024. The acquired resistome diversified over time, whereas the virulome remained largely conserved. Higher antimicrobial consumption in intensive care units was associated with carbapenem resistance. Sustained antimicrobial pressure likely contributed to the persistence and replacement of carbapenem-resistant lineages. Integrating genomic surveillance with antimicrobial stewardship may improve detection and control of high-risk hospital clones.\n\nID: 42419643\nTitle: Molecular characteristics and antimicrobial susceptibility profiling of carbapenem-resistant Pseudomonas aeruginosa clinical isolates in Korea: Implications for novel \u03b2-lactam therapy.\nAbstract: This study investigated the molecular epidemiology, cross-resistance to novel antibiotics, and clonal distribution of carbapenem-resistant Pseudomonas aeruginosa (CRPA) clinical isolates. Forty-three CRPA isolates were collected from sterile clinical specimens in the Republic of Korea (ROK) between 2015 and 2025. Susceptibility to 14 antibiotics was assessed in vitro by broth microdilution. Carbapenem-resistance mechanisms were characterized by using polymerase chain reaction (PCR), real-time quantitative reverse transcription PCR (RT-qPCR), and sequencing. Clonal diversity and epidemiological trends were examined by multilocus sequence typing (MLST). Among the 43 CRPA isolates, the susceptibility rates were 88.4% for both aztreonam-avibactam and cefiderocol, compared with 46.5% for ceftolozane-tazobactam and 39.5% for ceftazidime-avibactam. Among the 22 difficult-to-treat resistance (DTR) P. aeruginosa isolates, susceptibility rates were 77.3% for aztreonam-avibactam and 86.4% for cefiderocol. Carbapenemase genes were detected in 46.5% of isolates, predominantly blaNDM (41.9%). Porin loss and efflux pump overexpression were observed in 83.7% and 23.3% of isolates, respectively. Among the 22 P. aeruginosa isolates non-susceptible to both ceftolozane-tazobactam and ceftazidime-avibactam, 90.9% and 77.3% remained susceptible to aztreonam-avibactam and cefiderocol, respectively. MLST identified 12 sequence types (STs), with predominance of ST773 and ST644, both carrying blaNDM. CRPA exhibited multifactorial resistance driven by oprD disruption and blaNDM carriage within a diverse clonal structure dominated by ST773 and ST644. Aztreonam-avibactam and cefiderocol showed promising activity, supporting their role as critical therapeutic options.\n\nID: 42418271\nTitle: Beyond bacterial communication: host factors that modulate quorum sensing and virulence in human pathogens.\nAbstract: Quorum sensing (QS) coordinates collective bacterial behavior, but during infection, its activity is also shaped by host biology. This review examines how host-derived factors modulate QS-linked virulence in enteric pathogens, Pseudomonas aeruginosa and Staphylococcus aureus. Across these systems, host control operates through three recurring modes: activation or signal mimicry, enzymatic signal degradation, and extracellular sequestration or receptor-level interference. Catecholamines and related metabolites can feed into bacterial sensory pathways and promote virulence signaling; PONs (paraoxonases) and other host enzymes can degrade autoinducers; and lipoproteins, immune mediators, and epithelial surveillance systems can intercept or reinterpret quorum signals. Together, these data support the view that the host is an active signal-processing environment that reshapes colonization, persistence, and tissue damage, and they point to host-inspired anti-virulence strategies that target signaling rather than viability.\n\nID: 42417729\nTitle: Bacteriostatic activity of a perfluorooctyl bromide emulsion and its interaction with antibiotics against selected bacterial strains in vitro.\nAbstract: Antibiotic resistance is an increasing global public health concern. Perfluorooctyl bromide (PFOB) has demonstrated in-vitro bacteriostatic activity against Pseudomonas aeruginosa, but it is unknown whether this effect is maintained when PFOB is emulsified (PFOBe). This study aimed to evaluate the effect of PFOBe on the growth of antibiotic-resistant strains of P. aeruginosa, Staphylococcus aureus, and Klebsiella pneumoniae. Time-kill assays were performed to evaluate the activity of meropenem, gentamicin, oxacillin, PFOBe, and antibiotic-PFOBe combinations against resistant strains (K. pneumoniae ATCC BAA-2814, P. aeruginosa CeMoP 501, and S. aureus ATCC 33591) and antibiotic-susceptible strains (K. pneumoniae ATCC 700603, P. aeruginosa ATCC 27853, and S. aureus ATCC 25923). Morphological changes were assessed using scanning electron microscopy. PFOBe showed bacteriostatic activity against all tested strains and a limited enhancement of the antibiotics when combined. Structural alterations in bacterial cell walls were observed depending on the strain and treatment combination. PFOBe exhibits bacteriostatic activity and enhances against both resistant and susceptible bacterial strains, suggesting its potential as an adjuvant antimicrobial strategy.\n\nID: 42417593\nTitle: Molecular detection of carbapenemase genes in WHO priority pathogens from blood cultures of sepsis patients in Pakistan.\nAbstract: This study aimed to assess the antibiogram patterns of CR-GNB and to characterize carbapenemase-encoding genes among isolates obtained from patients with sepsis. A total of 3,746 blood culture samples were collected from patients with suspected septicemia and samples were processed using the BACTEC blood culture system, and all positive cultures were sub-cultured onto blood agar and MacConkey agar plates for isolation. Bacterial identification and antimicrobial susceptibility testing were performed using the VITEK 2 compact system following CLSI guidelines. Detection of antimicrobial resistance genes was carried out by PCR using gene-specific primers. Of 3,746 blood cultures, 873 (23.3%) were positive, yielding 577 (66.1%) Gram-negative isolates. Among these, 212 (24.3%) were CR-GNB, predominantly A. baumannii (41.5%), and K. pneumoniae (21.2%). MIC of meropenem among CR-GNB isolates ranged from >128 \u00b5g/mL to <1024 \u00b5g/ml. Overall, 47.2% of isolates were inhibited at 624\u00b5g/mL, followed by 38.2% at 312 \u00b5g/mL, and 12.7% at 156 \u00b5g/ml. In CR-A. baumannii, blaOXA-23 and blaNDM were detected in 71.6% and 62.5% of isolates, respectively. blaNDM was also present in K. pneumoniae (43.8%), and E. coli (40.7%).\u2009\u2009\u2009. There was a high prevalence of CR-GNB among septicemia patients, emphasizing the need for strict infection control measures to prevent their spread. Sepsis, or blood infection, is a serious and life-threatening condition that can affect people of all ages. In recent years, many of these infections have become harder to treat because some bacteria no longer respond to life-saving antibiotics called carbapenems. These bacteria are known as carbapenem-resistant Gram-negative bacteria and are listed by the World Health Organization as \u201cpriority pathogens.\u201d In Pakistan, infections caused by these resistant bacteria are increasing, but there is limited information about how common they are and what types of resistance they carry. Therefore, this study aimed to find these deadly bacteria in hospitals. This research will help doctors and health authorities understand the growing threat of antibiotic resistance in Pakistan. The results support better infection prevention, patient care, and national health policies to stop the spread of these serious pathogens.\n\nID: 42417318\nTitle: [Spectrum of pathogens and their antimicrobial resistance in cystitis, pyelonephritis, and prostatitis].\nAbstract: Infectious and inflammatory diseases of the genitourinary tract account for approximately 42% of all outpatient urology cases, and disorders such as cystitis, pyelonephritis, and prostatitis are often characterized by a chronic, recurrent course. One of the key contributors to recurrent urinary tract infections is inappropriate therapy that does not take into account the local microbial spectrum and pathogen resistance profiles. To determine the spectrum of uropathogens and their antimicrobial resistance patterns in patients with cystitis, pyelonephritis, and prostatitis. We analyzed the results of microbiological urine cultures from outpatient urology patients processed by the Invitro Laboratory between 2022 and 2024. In total, 4031 bacterial isolates were included: 2903 (72.0%) from patients with cystitis, 1017 (25.2%) from patients with pyelonephritis, and 111 (2.8%) from patients with chronic prostatitis. The structure of the microbial landscape differed by diagnosis. E. coli was the predominant pathogen in all groups, with a detection rate of 73.8-75.3% in cystitis and pyelonephritis, while in chronic prostatitis the rate was markedly lower at 53.1%. Klebsiella pneumoniae and Enterococcus faecalis were more frequently isolated in prostatitis (19.0% and 15.3%, respectively) compared with urinary infections, where their combined frequency ranged from 6.9% to 11.9%. Other pathogens (Proteus mirabilis, Streptococcus agalactiae, Enterobacter cloacae, Pseudomonas aeruginosa) accounted for 6.4% of isolates in cystitis, 7.6% in pyelonephritis, and 12.6% in prostatitis. Antimicrobial resistance was assessed for E.coli isolates. Resistance to amoxicillin/clavulanate was 24.9% in cystitis, 31.0% in pyelonephritis, and 38.9% in prostatitis. Levofloxacin resistance was observed in approximately one third of isolates from cystitis and in about half of isolates from pyelonephritis, whereas all E.coli isolates from prostatitis cases were susceptible. Resistance to trimethoprim-sulfamethoxazole in prostatitis was approximately twice as high as in cystitis and pyelonephritis. Urinary tract infections are predominantly caused by E.coli, while chronic prostatitis is associated with a more diverse spectrum of pathogens, with E.coli detected in only 53.1% of cases. Antimicrobial resistance profiles differ substantially between urinary infections and prostatitis, underscoring the importance of tailoring empirical therapy to local pathogen distribution and resistance patterns.\n\nID: 42417296\nTitle: [Carbapenem-resistant urinary tract infection in patients with nephrolithiasis].\nAbstract: Carbapenems belong to reserve antibiotics; however, the frequency of carbapenem-resistant bacterial strains is increasing in hospitals. Resistance of nosocomial Gram-negative strains to carbapenems is a significant problem with a tendency to progress, necessitating close attention to it. Analysis of the prevalence of carbapenem-resistant flora in a urology clinic, identifying the most significant factors associated with the resistance of pathogens to medications. A single-center retrospective study was conducted analyzing 1,720 urine culture results from patients with nephrolithiasis managed at a tertiary care institution in Moscow. Acquired carbapenem resistance to at least one carbapenem was detected in 5.4% of patients. Carbapenem-resistant Klebsiella pneumoniae (70% of all carbapenem-resistant isolates) and Pseudomonas aeruginosa (13%) were the most frequently identified species. Male sex and age >50 years were identified as significant risk factors. A logistic regression model was constructed to quantify the contribution of major risk factors, demonstrating an area under the receiver operating characteristic curve (ROC-AUC) of 0.88. The relatively high prevalence of carbapenem-resistant Gram-negative urinary tract infection among patients hospitalized for urological management of nephrolithiasis necessitates further research to identify optimal therapeutic strategies and prevent postoperative infectious complications caused by these pathogens. Moreover, the prevalence rate of carbapenem-resistant bacteria (5.4%) carries important implications for antimicrobial stewardship and pharmaceutical resource allocation in urological inpatient settings.\n\nID: 42415573\nTitle: An outbreak of multidrug-resistant Pseudomonas aeruginosa infections following flexible ureteroscopic stone removal.\nAbstract: Postoperative infections are an emerging concern in endourology. This study reports an outbreak of urinary tract infections associated with Pseudomonas aeruginosa (PA) in patients who underwent stone removal surgery using flexible ureteroscopy (FURS) at Seoul Medical Center. Between August and December 2024, five patients who underwent FURS performed by the same surgeon developed postoperative febrile episodes requiring further treatment. Urine cultures from four patients revealed an outbreak of multidrug-resistant PA, prompting environmental cultures and an inspection of the instrument reprocessing procedures led by the hospital's infection control department. Although PA was not isolated from the FURS itself, urine culture results showed identical antibiotic susceptibility profiles, and three patients exhibited temporal continuity, suggesting that the infections were related to surgery. No PA infections occurred among patients treated by other surgeons using single-use FURS during the same period, indicating that the infections were associated with the reusable FURS used solely by surgeon A. Environmental culturing detected PA on the sink and handle in the cleaning room, and deficiencies in the reprocessing procedures were identified. The FURS reprocessing protocol was revised to include ethylene oxide gas sterilization after each use, twice-daily disinfections of the sink where PA was identified, and replacement of handles and brushes. After implementing improvements to the reprocessing protocol, no further infections were reported over six months. Comprehensive device management may help prevent device related outbreaks. Given the complexity of FURS reprocessing, systematic management by trained personnel and ongoing monitoring are necessary to prevent device-associated infections.\n\nID: 42414940\nTitle: Distinct molecular epidemiology and outcomes of carbapenem-resistant gram-negative infections in Lebanon: insights from the MDRO network.\nAbstract: This study provides the first prospective, genomically validated dataset integrated into the global MultiDrug-Resistant Organism (MDRO) Network from the Middle East and North Africa region. To address the substantial gap in antimicrobial resistance (AMR) data, the American University of Beirut Medical Center (AUBMC) investigated carbapenem-resistant Enterobacterales (CRE), Acinetobacter baumannii (CRAB), and Pseudomonas aeruginosa (CRPA). Consecutive, hospitalized patients whose clinical cultures were positive for CRE, CRAB, or CRPA were prospectively enrolled between June 2018 and November 2019. Data on demographics, hospitalization, outcomes, and antimicrobial susceptibility were collected. Whole-genome sequencing (WGS) characterized the isolates. The primary outcome was the Desirability of Outcome Ranking (DOOR). Ninety-four patients were included: 35 with CRE, 19 with CRAB, and 40 with CRPA. Overall, 30% of patients survived without adverse events, whereas 33% experienced two or more adverse events. Patients with CRAB had the poorest prognosis, with only 5% surviving without complications, and a significantly different DOOR distribution versus CRE or CRPA (p\u2009=\u20090.023). Adjusted DOOR probabilities confirmed the poorer outcomes associated with CRAB: when compared with CRE or CRPA, a randomly selected CRAB patient had only a 37.7% (95% CI, 24.9-52.6%) and 38.8% (95% CI, 26.5-52.7%) probability of achieving a more desirable outcome, respectively. WGS identified blaNDM-5 (24%) and blaOXA-48 (24%) as the most common genes in CRE, blaOXA-23 in all CRAB strains, and blaVIM-2 in 88% of CRPA strains. The dominant clones were CG383 K. pneumoniae (CRE), CG2 (CRAB), and CG111 (CRPA). MDRO infections in Lebanon have distinct molecular patterns compared to the US, Chinese, South American, and Australian cohorts, as well as poor outcomes, especially with CRAB. Ongoing surveillance, strengthening regional collaboration, and future clinical trials are essential to guide diagnostic and therapeutic strategies in settings with increasing AMR.

NCT03646227. 15-08-2018.\n\nID: 42414298\nTitle: Role of starvation survival response mechanisms on ribosome integrity, antibiotic tolerances, and virulence of Pseudomonas aeruginosa biofilms.\nAbstract: Bacterial biofilms contain physiologically diverse subpopulations of cells, including cells that are nutrient stressed or dormant. We determined how two dormancy pathways, ribosome hibernation and the stringent response, contribute to the survival and antibiotic tolerance of Pseudomonas aeruginosa biofilms. Analyses of whole biofilms and single cells showed that these pathways have differing effects on biofilm cell physiology. Ribosome hibernation, mediated by hibernation promoting factor (HPF), is essential for optimal survival and resuscitation of starved biofilm cells. In the absence of HPF, starved cells progressively lose ribosome integrity. However, loss of HPF does not increase the sensitivity of P. aeruginosa biofilm cells to ciprofloxacin or tobramycin. In contrast, the stringent response, mediated by RelA and SpoT, is not required for viability or ribosome integrity in starved biofilm cells, but does affect biofilm antibiotic tolerance. In a plant model of biofilm infection, disruption of either ribosome hibernation or the stringent response reduced bacterial virulence. The results show that ribosome hibernation preserves ribosomal integrity necessary for recovery from starvation and for pathogenesis, while the stringent response is required for growth arrest, antibiotic tolerance, and pathogenesis. These two ribosome-mediated pathways play distinct yet complementary roles in regulating dormancy and persistence of P. aeruginosa biofilms.\n\nID: 42413747\nTitle: Mechanism of injury influences early microbial trajectories and infection pathways in open fractures: A 16S rDNA study.\nAbstract: The mechanism of injury in open fractures-whether blunt or sharp- may significantly impact early microbial colonization and how those microbial communities develop in relation to wound microbiota, which leads to fracture-related infection (FRI). Nevertheless, the influence of trauma biomechanics on infection development and microbial community dynamics is poorly studied. This study aimed to assess how different injury mechanisms influence wound microbiota dynamics and susceptibility to FRI. In this prospective cohort study, we recruited 155 patients with Gustilo-Anderson type II, IIIA, or IIIB open fractures. Deep tissue samples were obtained from all patients during their initial surgical debridement. In a subset of 28 patients who developed FRI, a second sample was collected at the time of re-debridement. The samples were matched and stratified into four groups based on trauma mechanism and infection status: Pre-debridement sharp, Pre-debridement blunt, Infection sharp, and Infection blunt. Microbial profiling was conducted using 16S rDNA sequencing. The sample metadata was analyzed in QIIME2, from which diversity indices (alpha and beta) were computed. The taxonomic composition and abundance were assessed at the genus level, while patterned relationships between groups were visualized through heatmap clustering. Beta diversity analysis showed that Pre-debridement sharp group clustered closely with both infection groups, significantly diverging from the Pre-debridement blunt group (p\u202f<\u202f0.001). In terms of alpha diversity, the Pre-debridement sharp group exhibited the highest levels across richness, evenness (p\u202f<\u202f0.05), as well as phylogenetic breadth. Taxonomic profiling showed that sharp trauma wounds were initially enriched with potentially pathogenic genera such as Pseudomonas, Acinetobacter and Staphylococcus, while blunt trauma wounds were dominated by low virulence taxa, like Bacillus. Heatmap analysis confirmed that the microbial composition of sharp samples was similar to those from both infection groups, suggesting that sharp trauma wounds possess a diverse microbial community that resemble the architecture seen in FRI. While the overall infection rate did not differ between blunt and sharp trauma, the mechanism of injury significantly influenced early microbial colonization patterns and infection development pathways. These findings emphasize the importance of trauma-specific microbiota profiling in understanding and potentially guiding the prevention of FRI.\n\nID: 42413686\nTitle: Value of the Pitt bacteremia score in predicting the outcome of non-bacteremic patients with infections caused by multidrug-resistant organisms.\nAbstract: Infections caused by multidrug-resistant organisms (MDROs) are increasingly associated with significant morbidity and mortality. Early identification of high-risk patients is essential. The Pitt Bacteremia Score (PBS) is validated in bloodstream infections, but its role in non-bacteremic infections remains unclear. To evaluate the performance of the PBS in predicting mortality among patients with non-bacteremic MDRO infections and compare it with the quick Sequential Organ Failure Assessment (qSOFA) score and the Charlson Comorbidity Index (CCI). We conducted a 5-year retrospective study at a tertiary care center including adults (>18 years) admitted between December 2018 and December 2023 with confirmed non-bacteremic MDRO infections. Organisms included methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), carbapenem-resistant Pseudomonas aeruginosa (CRPA), carbapenem-resistant Enterobacterales (CRE), and carbapenem-resistant Acinetobacter baumannii (CRAB). Patients with bloodstream infection, colonization, ICU stay >48 hours, severe COVID-19, or terminal illness were excluded. Separate multivariable logistic regression models were constructed for PBS, qSOFA, and CCI. Discriminatory performance was assessed using receiver operating characteristic (ROC) curve analysis. Among 202 patients (mean age 62.1 \u00b1 18.3 years; 67.8% male), in-hospital mortality was 21.3%. In multivariable analyses, PBS (aOR 1.75, 95% CI 1.49-2.05; p<0.001) and qSOFA (aOR 11.46, 95% CI 5.37-24.47; p<0.001) remained independently associated with mortality, whereas CCI did not retain statistical significance after adjustment. Age remained an independent predictor in all models, while time to effective antimicrobial therapy was independently associated with mortality in the CCI model (aOR 0.62, 95% CI 0.47-0.81; p<0.001). PBS demonstrated excellent discriminatory performance (AUC 0.939, 95% CI 0.897-0.968), outperforming qSOFA (AUC 0.883) and CCI (AUC 0.696). PBS is a strong predictor of in-hospital mortality in patients with non-bacteremic MDRO infections and demonstrated superior discriminatory performance compared with qSOFA and CCI. These findings support its use as an early risk-stratification tool in this high-risk population.\n\nID: 42413502\nTitle: TACTIC: A transfer learning framework to predict drug interactions in emerging pathogens.\nAbstract: Machine learning (ML) is necessary to efficiently identify potent drug combinations within a large candidate space to combat drug resistance. However, existing ML approaches cannot be applied to emerging and understudied pathogens with limited training data. Hence, we developed a computational framework (TACTIC [transfer-learning and cross-species training to infer combination therapies]) to train ML models on data from multiple model bacteria. TACTIC was built using 2,965 drug interactions from 12 bacterial strains and outperformed traditional ML models in predicting drug interaction outcomes for species with limited training data. Upon analyzing \u223c600,000 predicted drug interactions across 18 pathogenic and commensal strains, we identified interactions that are selectively synergistic against Gram-negative and mycobacterial pathogens. We experimentally validated synergistic drug combinations containing clarithromycin, ampicillin, and mecillinam, against clinical strains of M. abscessus, an emerging drug-resistant pathogen. We also confirmed 11 synergistic combinations against Pseudomonas aeruginosa and Staphylococcus aureus strains that cause endophthalmitis.\n\nID: 42413100\nTitle: Respiratory infectious diseases in intensive care units\u2019 patients during 2024, in two hospitals in Guayaquil, Ecuador.\nAbstract: Introduction. Viral, bacterial, and fungal infections represent a major health concern, contributing significantly to increased morbidity and mortality in respiratory diseases. Objective. To characterize respiratory infections and their etiological agents in patients admitted to intensive care units during the first six months of 2024. Materials and methods. An observational, cross-sectional, prospective study was conducted in two hospitals between January 1st. and June 30th., 2024. Clinical and microbiological data were collected (dates, age, sex, type of sample, results, and diagnoses) and analyzed using IBM SPSS\u2122 Statistics 27.0. Results. Of the 56 patients admitted, 35 presented respiratory infections, predominantly in females, with a mean age of 49 years. The following agents were identified: rhinovirus/enterovirus, influenza A, coronavirus, parainfluenza, and respiratory syncytial virus. Among the most frequent bacteria found were: Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, Pseudomonas aeruginosa, Haemophilus influenzae, Enterobacter cloacae, Escherichia coli, Proteus spp., Stenotrophomonas maltophilia, Serratia marcescens, Streptococcus agalactiae and S. pneumoniae. Bacterial resistance genes such as CTX-M, KPC, mecA/mecC, and MREJ, NDM, Oxa48-like, and VIM were also detected. In the case of fungal infections, Candida albicans and Candida glabrata were isolated. Most patients with respiratory illness progressed to hospital-acquired pneumonia. Conclusion. During the study period, respiratory infections in the intensive care units were mainly associated with bacterial pathogens, with a high frequency of hospital-acquired pneumonia and the detection of antimicrobial resistance genes.

Acinetobacter baumannii is an opportunistic pathogen responsible for severe hospital-acquired infections, including bloodstream infections (BSIs). Although major epidemic clones and resistance mechanisms have been described, integrated analyses combining clinical features, patient outcomes and genomic characteristics of BSI isolates remain limited, particularly in China.Gap Statement. Comprehensive analyses integrating clinical outcomes, high-resolution genotyping, capsule locus diversity and their associations with mortality are still lacking.Aim. This study aimed to characterize the clinical characteristics and outcomes of patients with A. baumannii BSIs, as well as the phenotypic and genomic characteristics of the causative isolates. Specifically, we sought to identify high-risk clones and their association with 30-day mortality to improve diagnostic and therapeutic strategies.Methodology. A retrospective cohort study was conducted on 151\u2009cases of A. baumannii BSIs in a tertiary hospital in China. Isolates were analysed using whole-genome sequencing to determine sequence types (STs), capsule loci and resistance and virulence gene profiles.Results. The 151 isolates were classified into 11 different STs using the Pasteur MLST scheme, with ST2Pasteur predominating (88.1%). One isolate represented a novel Pasteur ST (ST2831Pasteur). Using the Oxford MLST scheme, 22 STs were identified, with ST195Oxford, ST208Oxford and ST540Oxford being the most common. Four novel Oxford STs (ST2457Oxford, ST2458Oxford, ST2459Oxford and ST2460Oxford) were identified. Twenty-three capsule locus (KL) types were detected, with KL3 being the most prevalent. Phylogenetic analysis showed clear clustering according to STs and KL types. The ST2Pasteur lineage was characterized by the presence of the OXA-23 gene and carbapenem resistance, as well as an expanded virulence gene repertoire, suggesting enhanced pathogenic potential. The overall 30-day mortality rate was 35.1%. Patients in the death group had shorter hospital stays, fewer surgical interventions and higher rates of complications, invasive procedures and intensive care unit admission. Certain clone combinations, including ST369Oxford-KL9, ST938Oxford-KL210 and ST195Oxford-KL3, were associated with higher mortality rates.Conclusion. ST369Oxford-KL9, ST938Oxford-KL210 and ST195Oxford-KL3 represent high-risk clones associated with A. baumannii BSIs. Early identification of ST and capsule type, alongside clinical risk stratification, may improve diagnosis and guide treatment strategies.\n\nID: 42412311\nTitle: Using the Damage Response Framework as a Lens to Discuss Acinetobacter baumannii Host-Pathogen Interactions: A Narrative Review and a Call to Action.\nAbstract: The Damage Response Framework (DRF) is a conceptual model that evaluates the outcome of host-pathogen interactions (HPI) by assessing the total damage sustained by the host. The DRF emphasizes that disease results from cumulative host injury arising from the interplay between microbial virulence and the host immune response, rather than from the pathogen alone. HPI has been described as a \"tug of war\" between a pathogen and a host; the DRF improves this analogy by grounding it in reality, as both excessive immune activation and insufficient pathogen clearance can lead to host damage and disease. Acinetobacter baumannii is a Gram-negative pathogen known for its extensive drug resistance and immunomodulatory capacities. The interaction among isolate-specific virulence traits, antimicrobial resistance mechanisms, and host immune status determines the pattern and extent of damage, illustrating central tenets of the DRF. Different A. baumannii isolates may therefore produce varied clinical outcomes across different host conditions, depending on the extent of damage they cause. This narrative review discusses A. baumannii infections from the perspective of the DRF, highlighting how applying the DRF can inform our current understanding of A. baumannii pathogenesis by assessing A. baumannii HPI. We also provide brief insights into how the DRF can inform future research and treatment strategies that integrate host and microbial factors to minimize overall damage and improve host outcomes. A. baumannii infections are difficult to treat and can result in outcomes ranging from asymptomatic colonization to fatal disease. This narrative review examines these differences through the Damage Response Framework (DRF) to improve understanding of A. baumannii infections. The DRF emphasizes that disease results not only from the microbe but also from the interaction between microbial factors and the body\u2019s immune response. When the total damage from the microbe and the immune response exceeds the body's ability to repair, hosts become sick. Hosts with weak immune responses can become very ill because their immune systems cannot control the infection effectively. Conversely, patients with strong immune responses can also become severely ill when their immune systems damage vital tissues and organs in an effort to eliminate the bacteria. This narrative review draws on existing literature to show that different A. baumannii isolates can cause varying levels of illness, depending on the host\u2019s response to the infection. The review also briefly describes the importance of considering antimicrobial therapy as a potential source of host damage and the utility of the DRF in optimizing therapeutic strategies.\n\nID: 42412160\nTitle: Lactobacillus strains in the prevention and disruption of antimicrobial-resistance in pathogenic microbial biofilms: a review of mechanisms and clinical perspective.\nAbstract: The growing prevalence of antibiotic resistance, coupled with the heightened drug tolerance exhibited by biofilm-associated infections, represents a major public health challenge and demands the development of innovative therapeutic interventions. Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation. Studies demonstrate robust efficacy of probiotics against clinically challenging pathogens, including methicillin-resistant Staphylococcus aureus, multidrug-resistant Pseudomonas aeruginosa, Clostridioides difficile, Helicobacter pylori, and pathogenic Escherichia coli. Postbiotics, particularly cell-free supernatants and purified bacteriocins, offer standardized, shelf-life probiotic products. Notably, synergistic combinations with conventional antibiotics, phytochemicals, or bacteriophages enhance antimicrobial activity while enabling dose-reduction strategies to mitigate the development of resistance. However, compelling preclinical evidence, clinical translation remains constrained by the imperative for strain-specific characterization, methodologically robust randomized controlled trials, and comprehensive safety validation. This study critically mentions current mechanisms underlying Lactobacillus-mediated anti-biofilm strategies and identifies priority research essential to accelerating clinical application.\n\nID: 42412003\nTitle: Host-directed antimicrobial peptide biomaterials for combating Gram-negative bacterial infections.\nAbstract: Antimicrobial resistance (AMR) represents a defining crisis in modern infectious disease medicine. Gram-negative microbes such as carbapenem-resistant Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae are becoming more resistant than ever. Traditional methods of treatment using antibiotics are ineffective because of the presence of several envelope layers, active efflux pumps, and biofilm production. In contrast, bacteriolytic therapy can exacerbate host immunopathology owing to systemic endotoxin release. Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment; however, clinical use remains hindered by their low stability, high binding to serum proteins, and narrow therapeutic index. In this review, we will discuss the use of biomaterial platforms in the design of peptide-based therapeutics to not only increase their efficacy by reducing peptide clearance but also optimize the immunological environment in which these peptides operate. We will discuss the role of various characteristics, such as surface chemistry, mechanical stiffness, and protein corona, in influencing macrophage polarization and downstream signaling pathways. In addition, we point out a significant limitation within this area of research: many preclinical studies continue to use minimum inhibitory concentration and hemolysis values, which fail to account for the host-directed effects that make these approaches significant. For future progress in this realm, new endpoints are required, along with more clinically relevant animal models and a true incorporation of peptide design into biomaterials engineering.\n\nID: 42411263\nTitle: Dual Sub\u2011MIC Copper-Gentamicin Stress Drives Strain\u2011Specific, Non\u2011Additive Phenotypic Shifts in Pseudomonas aeruginosa.\nAbstract: Exposure to redox\u2011active metals and sub\u2011inhibitory antibiotics represents a significant selective pressure shaping bacterial physiology and antimicrobial susceptibility. Here, we investigated how four genetically and phenotypically distinct Pseudomonas aeruginosa strains respond to sub\u2011MIC copper (Cu) and gentamicin (GE) stress, individually and in combination (Cu\u2009+\u2009GE). Across all strains, Cu acted as the dominant envelope\u2011active stressor, increasing biofilm biomass and extracellular DNA (eDNA) release, suppressing twitching and swarming motility, reducing quorum\u2011sensing\u2011linked protease activity, and enhancing pyomelanin production. GE alone produced limited physiological changes but modulated Cu\u2011driven outputs during co\u2011exposure, including attenuation of Cu\u2011induced eDNA release and strain\u2011specific shifts in motility and pigmentation. Early transcriptional profiling revealed consistent Cu\u2011dependent repression of lasI and mvfR, induction of the metal\u2011responsive regulator czcR, and downregulation of oprD under Cu or Cu\u2009+\u2009GE, corresponding to reduced imipenem inhibition zones when Cu was present during susceptibility testing. Combined Cu\u2009+\u2009GE exposure produced non\u2011additive, emergent effects that diverged from single\u2011stressor responses and varied across strains. These findings demonstrate that sub\u2011inhibitory Cu creates an envelope\u2011centered regulatory landscape into which gentamicin\u2011derived signals are integrated, generating heterogeneous and context\u2011dependent phenotypes. This work underscores the importance of metal-antibiotic interactions in shaping bacterial adaptation and highlights limitations of single\u2011stressor models for predicting antimicrobial behavior in combination.\n\nID: 42410515\nTitle: Antimicrobial resistance profiles of ESKAPE pathogens isolated in a microbiology laboratory in Somalia: a two-year retrospective study.\nAbstract: ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp.) are major causes of healthcare-associated infections and pose a serious public health threat because of their high antimicrobial resistance potential. This study evaluated the distribution, resistance profiles, and associated factors of ESKAPE pathogens isolated in Somalia. This retrospective single-center laboratory-based study was conducted at Mogadishu Somalia T\u00fcrkiye Recep Tayyip Erdo\u011fan Training and Research Hospital, a tertiary care center in Mogadishu, Somalia. Only culture-positive clinical specimens yielding ESKAPE pathogens between January 2024 and December 2025 were included. A total of 2,486 ESKAPE isolates were analyzed. Antimicrobial susceptibility testing was performed using the Kirby-Bauer disk diffusion method according to CLSI criteria. Demographic and clinical data were analyzed using SPSS and R software. Associations between selected demographic and clinical factors and specific pathogens were evaluated using univariate binary logistic regression analysis. Of the isolates, 1,442/2,486 (58.0%) were obtained from male patients, and the most common age group was 18-40 years [952/2,486 (38.3%)]. The most prevalent pathogens were K. pneumoniae [1,033/2,486 (41.6%)] and S. aureus [629/2,486 (25.3%)]. Overall, MDR and XDR phenotypes were detected in 1,633/2,486 (65.7%) and 687/2,486 (27.6%) isolates, respectively. The highest MDR and XDR rates were observed in A. baumannii [135/138 (97.8%) and 97/138 (70.3%)]. High resistance to ceftazidime [128/138 (92.8%)], cefepime [116/138 (84.1%)], ciprofloxacin [115/138 (83.3%)], trimethoprim-sulfamethoxazole [121/138 (87.7%)], and carbapenems [99/138 (71.7%)] was detected in A. baumannii. Susceptibility to vancomycin and linezolid remained largely preserved among Gram-positive pathogens. A. baumannii and Enterobacter spp. were significantly associated with ICU admission, while gender-related differences were observed for P. aeruginosa and S. aureus. A high burden of antimicrobial resistance was observed among ESKAPE pathogens, particularly Gram-negative bacteria, with A. baumannii playing a central role. These findings provide important local surveillance data that may support empirical antibiotic selection, antimicrobial stewardship, and infection control strategies in Somalia.\n\nID: 42410210\nTitle: Non-canonical gene amplifications facilitate adaptive evolution in bacteria.\nAbstract: Gene amplification, a common route to bacterial adaptation, often occurs through recombination between two copies of an insertion sequence (IS) element flanking a genomic region. Alternative non-canonical structures have also been proposed, in which a duplication is formed by a single IS element whose two ends join two distant chromosomal loci. However, the prevalence of such non-canonical structures and their role in bacterial adaptive evolution remain unclear. Here we developed AmpliFinder, a computational tool that uses short-read sequencing data to systematically identify pairs of IS-chromosome junctions that correspond to the two ends of the same IS element yet map to distant genomic loci flanking amplified regions. Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification. We validated the inferred architectures using ultra-long-read sequencing and propose a model for non-canonical amplification formation supported by the observation of nested intermediate structures. Quantifying enrichment for antibiotic-resistance genes in amplicons, we find that non-canonical amplifications more effectively and narrowly amplify genes under selection. These results highlight the role of non-canonical IS-based amplifications in the adaptive evolution of bacteria.\n\nID: 42409517\nTitle: Synergistic inhibition mechanism of slightly acidic electrolyzed water combined with \u03b5-polylysine hydrochloride against Pseudomonas fluorescens.\nAbstract: This study explored the synergistic inhibition mechanism on combining slightly acidic electrolyzed water (SAEW) and \u03b5-polylysine hydrochloride (\u03b5-PLH) against Pseudomonas fluorescens, a key spoilage bacterium in aquatic products. A significant synergistic antibacterial effect was achieved with the fractional inhibitory concentration index being 0.5 when the two agents were combined at their respective 1/4 of minimum inhibitory concentration. Mechanistic studies revealed that the combined treatment severely disrupted bacterial membrane integrity and potential, inhibited biofilm formation, and caused extensive cell lysis in P. fluorescens PF08. Fourier transform infrared spectroscopy further indicated that the combined treatment caused the most severe damage to cell wall peptidoglycan, proteins, and polysaccharides. Non-targeted metabolomics disclosed that SAEW primarily disturbed histidine and lysine metabolisms, while \u03b5-PLH interfered with arginine and glutathione metabolisms, and their combination triggered broader metabolic reprogramming in the strain, demonstrating a multi-target antibacterial mechanism. This study provides a theoretical basis for the application of the SAEW-\u03b5-PLH composite green antibacterial agent in the preservation of aquatic raw materials and their prefabricated meal products which is perishable due to contamination by P. fluorescens.\n\nID: 42409485\nTitle: Analysis of the antibacterial mechanism and antivirulence efficacies of citral against Shewanella putrefaciens and Pseudomonas fluorescens in mono- and co-culture.\nAbstract: Shewanella putrefaciens and Pseudomonas fluorescens, as significant specific spoilage organisms in aquatic products, can regulate cell density and a variety of physiological processes through quorum sensing (QS). This research examined the antibacterial mechanism and antivirulence efficacies of citral (CT), as a quorum sensing inhibitor (QSI), against S. putrefaciens and P. fluorescens in mono- and co-culture. Furthermore, the application of CT to large yellow croaker preservation was investigated. Results revealed that CT exerted its antibacterial activities in a dose-dependent manner. CT increased intracellular oxidative stress levels and malondialdehyde (MDA) content, decreased ATP content and peroxidase activity, and promoted the damage of cell membrane, especially in S. putrefaciens group. These two bacteria had a synergistic effect in causing spoilage through biofilm formation and motility. The antivirulence efficacies of CT against the co-culture group were weaker than those of in the mono-culture groups. CT was also found to suppress the expression of key virulence regulators in S. putrefaciens and P. fluorescens virulence, including Autoinducers-2 (AI-2) production in the QS system. Furthermore, CT had the potential capability in the preservation of large yellow croaker. Consequently, these results proved CT could combat bacteria and had antivirulence efficacies against S. putrefaciens and P. fluorescens in mono- and co-culture.\n\nID: 42409126\nTitle: Arginine metabolism and compensatory adaptations expand the impaired phage resistance repertoire in colistin-resistant Acinetobacter baumannii.\nAbstract: Limiting the emergence of phage resistance is a key priority in optimizing phage therapy. However, it remains poorly understood whether the development of antibiotic resistance influences the evolution of phage resistance. To investigate phage-host interactions, we used both colistin resistant strains derived from the wild-type and genetically engineered knockout mutants. Transcriptomic analysis was employed to examine the adaptive responses of these colistin-resistant mutants under phage pressure. Finally, we characterized the phage-resistant variants that evolved in the colistin-resistant backgrounds. Our results demonstrate that the emergence of phage-resistant variants was significantly reduced in colistin resistant mutants. These phenotypic changes were primarily mediated by disruption of lpxC and lpxD, with additional effects from compensatory mutations and amino acid metabolism. The \u0394lpxC and \u0394lpxD mutants exhibited distinct transcriptional profiles and metabolic features under phage pressure. The astA-mediated arginine metabolism pathway was a key modulator of phage-colistin-resistant mutant interactions. In the \u0394lpxD background, Mla system inactivation and arginine supplementation accelerated the phage resistance evolution (including via the mucoid phenotype). Capsule defects arising during phage resistance development in both \u0394lpxC and \u0394lpxD mutants simultaneously increased colistin susceptibility. Overall, lpxC/lpxD disruption constrains phage resistance evolution in A. baumannii. Compensatory mutation and bacterial metabolism not only mitigate fitness cost and maintain antimicrobial resistance but also expand evolutionary trajectories of bacteria under phage pressure. These findings reveal the adaptive mechanisms of colistin-resistant A. baumannii under phage selection and support the optimization of phage therapy.\n\nID: 42407157\nTitle: CRISPR-based diagnostics for ESKAPE drug-resistant bacteria: From proof-of-concept to point-of-care.\nAbstract: The ESKAPE pathogens, including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species, represent a major challenge in the antimicrobial resistance (AMR) crisis. These pathogens are progressively acquiring pan-resistance and spreading beyond traditional healthcare settings, yet conventional diagnostic methods remain ill-equipped for point-of-care (POC) deployment due to slow processing times and limited adaptability. CRISPR/Cas systems feature programmable target specificity and intrinsic signal amplification, enabling rapid and accurate nucleic acid detection. Despite these advantages, the translation of CRISPR-based assays for ESKAPE pathogens from proof-of-concept to practical POC tools faces major challenges. Current research is fragmented, and key trade-offs between sensitivity, multiplexing performance and operational simplicity have not been fully addressed. This review offers a critical assessment of the field, moving beyond a simple summary of existing studies to analyze how various CRISPR systems (Cas9, Cas12, Cas13, and Cas14) and amplification strategies address the demands of POC testing. We identify key barriers to clinical application, particularly sample preparation, multiplex detection, reagent stability, and discuss emerging solutions such as microfluidic integration, lyophilized reagents development, and artificial intelligence-driven data interpretation. By focusing on the central question of how to transition from benchtop research to bedside application, this review provides a strategic framework for advancing next-generation CRISPR diagnostics capable of rapid, precise, and real-time detection of drug-resistant ESKAPE pathogens in the fight against AMR.\n\nID: 42406312\nTitle: Genomic landscape of 340 virulent Acinetobacter bacteriophages reveals anti-CRISPR-enriched candidates for therapeutic prioritization.\nAbstract: Carbapenem-resistant Acinetobacter baumannii (CRAB) represents a critical global health threat for which existing antibiotics are increasingly inadequate. This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates. We performed large-scale comparative genomic analysis of 340 virulent Acinetobacter bacteriophages, integrating phylogenetic reconstruction, pangenome analysis, CRISPR spacer-based host interaction mapping, Anti-CRISPR protein identification, and systematic antimicrobial resistance (AMR) gene screening. Genome sizes spanned a nearly 20-fold range, with a significant negative correlation between genome size and GC content (R\u00b2 = 0.139, \u03c1 = -0.630). Phylogenetic analysis revealed extensive divergence across multiple lineages with no dominant clade. Pangenome analysis identified 20,982 unique protein families, of which 76.2% were cloud genes, confirming a highly open genome architecture. CRISPR spacer matching yielded 1,480 high-confidence matches across 100 phage genomes, providing molecular evidence of broad historical infectivity. Anti-CRISPR profiling identified Acinetobacter phage XC1 as an exceptional therapeutic candidate harboring 55 predicted Anti-CRISPR proteins with canonical regulatory locus architecture. AMR screening identified 21 distinct AMR gene homologs (Loose RGI hits, 22.5 to 47.1% amino acid identity) distributed heterogeneously across the dataset, confirming abundant therapeutically clean candidates while flagging a subset warranting further scrutiny before therapeutic exclusion. These findings provide a multi-criteria genomic framework for rational phage candidate prioritization against multidrug-resistant Acinetobacter infections, with direct implications for evidence-based phage therapy development.\n\nID: 42406180\nTitle: Next-generation biodegradation of chlorpyrifos: integrative microbial strategies, molecular mechanisms, and environmental impacts.\nAbstract: Chlorpyrifos (CP) belongs to organophosphate pesticide group. It is extensively applied in agricultural and household settings due to its broad-spectrum insecticidal properties. However, its persistence, bioaccumulative behavior, and toxicological effects on non-target organisms, including humans, pose significant environmental and public health concerns. CP and its metabolites, particularly two including 3,5,6-trichloropyridinol (TCP) and chlorpyrifos-oxon (CPO), have been recently reported to be widely found various samples such as in soils, sediments, water bodies, crops, and even human biological fluids. These compounds disrupt biogeochemical cycles, alter soil microbial communities, inhibit enzyme activities, and are linked to neurotoxicity, endocrine disruption, and genotoxic effects. Conventional remediation strategies such as photodegradation, ultrasonication, and filtration remain ineffective due to incomplete degradation and secondary pollution risks. Recent studies highlight the efficiency of microbial degradation, especially by bacteria such as Bacillus, Klebsiella, Pseudomonas and Enterobacter as a promising, eco-friendly alternative. These microorganisms utilize CP as a only carbon source, and degradation calibre is greatly governed by various abiotic factors like pH, temperature, and moisture. The genetic as well as enzymatic analyses reveal key roles of organophosphorus hydrolases encoded by genes such as opd and mpd. The integration of plant growth-promoting traits and laccase activity further enhances their bioremediation capability. Additionally, recent advancements in biosensing techniques for CP detection offer improved sensitivity and real-time monitoring. This review provides a comprehensive analysis of CP's environmental fate, toxicological impact, degradation pathways, and the emerging role of bacterial bioremediation, highlighting its potential for sustainable environmental detoxification.\n\nID: 42420828\nTitle: Occurrence of antimicrobial-resistant, extended-spectrum beta-lactamase and carbapenemase-producing bacterial isolates from intensive care unit environment in two hospitals of Ethiopia.\nAbstract: Intensive care unit environments are a critical reservoir of antimicrobial-resistant bacterial species and facilitate the transmission of nosocomial infections. This unit harbors multidrug-resistant organisms, thereby complicating the management of infectious diseases within clinical settings, particularly in resource-limited countries. This study, therefore, aimed to determine the occurrence and antimicrobial resistance profiles of bacteria, including Extended-spectrum beta-lactamase- and Carbapenemase-producing isolates, in the intensive care units of two hospitals in Addis Ababa, Ethiopia. A repeated cross-sectional study was conducted in Addis Ababa, Ethiopia, from July 2024 to April 2025. A total of 239 swab samples were collected from adult and neonatal intensive care unit environments during both the dry and rainy seasons. Samples were collected and processed aseptically. Bacterial identification and antimicrobial susceptibility testing were performed according to CLSI guidelines. From the total samples collected, 162/239 (67.8%) bacterial isolates were recovered from the Intensive Care Unit environment. Klebsiella pneumoniae 22/162 (13.6%) and Pseudomonas aeruginosa 21/162 (13%) were the most frequently isolated bacterial species. All P. aeruginosa were resistant to ceftazidime, while 19/22 (86.3%) and 18/22 (81.8%) of K. pneumoniae were resistant to cefuroxime and cefotaxime, respectively. All S.haemolyticus were also resistant to penicillin, and 8/12 (66.7%) of Enterococcus spp were resistant to erythromycin. Multidrug-resistant bacteria were seen in 89/150 (59.3%) of isolates. The highest multidrug resistance rate was obtained for Pseudomonas aeruginosa 18/21 (85.7%), followed by Klebsiella pneumoniae 16/22 (72.7%) and Acinetobacter spp 8/11 (72.7%). Extended-spectrum \u03b2-lactamase-producing isolates accounted for 23/105 (21.9%), and Carbapenemase-producers comprised 10/105 (9.5%). The environments within intensive care units are conducive to the proliferation of multidrug-resistant microorganisms, encompassing bacterial isolates that produce extended-spectrum beta-lactamases and carbapenemases, thereby complicating the management of infectious diseases. Consequently, it is crucial to address the issue of antimicrobial resistance in this critical setting to mitigate the incidence and dissemination of resistant bacteria, which may lead to the emergence of nosocomial infections.\n\nID: 42420327\nTitle: Pulmonary mRNA-LNP vaccines for rapid and durable protection against bacterial infection.\nAbstract: Pulmonary bacterial infections remain a major clinical challenge. Although vaccination reduces infection rates and mortality, the vulnerable post-vaccination immunity gap can still result in infection and vaccine failure. In addition, effective vaccines are unavailable for many clinically important bacterial pathogens. Here, we report a pulmonary mRNA-lipid nanoparticle (mRNA-LNP) vaccine incorporating an ionizable lipid engineered for localized high-level expression, which elicits both rapid and durable protection against bacterial lung infections in female mice, effectively bridging this critical window of vulnerability. Intratracheal delivery of mRNA-LNP rapidly primes lung neutrophils and macrophages into a transcriptionally pre-activated state, enhancing their phagocytic activity and enabling rapid, antigen-independent bacterial clearance during the early post-vaccination period (approximately 1-7 days). Subsequently, vaccination induces potent antigen-specific adaptive responses, conferring sustained protection against both laboratory and clinical drug-resistant Pseudomonas aeruginosa strains. Single-cell transcriptomics and immune profiling reveal coordinated activation of innate and adaptive immune programs. This dual-phase immune response exemplifies a paradigm-shifting vaccine design that integrates innate and adaptive immunity to confer both immediate and long-term protection. Our findings establish a mechanistic basis for rapid antibacterial defense and highlight pulmonary mRNA-LNP vaccination as a promising strategy for combating respiratory infections.\n\nID: 42419029\nTitle: Metagenomic investigation of VIM-type metallo-\u03b2-lactamase-producing multidrug-resistant Pseudomonas aeruginosa associated with a hospital outbreak across multiple hospital units in Saudi Arabia.\nAbstract: Healthcare-associated infections (HAIs) caused by multidrug-resistant (MDR) Pseudomonas aeruginosa (P. aeruginosa) represent a public health challenge, particularly when associated with VIM-type metallo-\u03b2-lactamases (MBLs), which limit therapeutic options. Conventional microbiological methods may underestimate resistance determinants and transmission dynamics. Long-read metagenomic sequencing is a promising approach for Pathogen detection, resistome characterization, and genomic surveillance. The study's objectives were to characterize the resistome, including detection of the blaVIM gene, assess genomic relatedness and potential transmission dynamics, and evaluate the diagnostic value of metagenomics compared with conventional microbiological approaches. This retrospective infection control investigation included seven hospitalized patients from multiple hospital units. Clinical specimens included blood, respiratory specimens, surgical tissue, and device-associated material. Conventional microbiological investigations included bacterial culture, identification, and antimicrobial susceptibility testing (AST) using the VITEK 2 automated system. Carbapenemase genes were detected using Xpert Carba-R. Long-read metagenomic sequencing was conducted using Oxford Nanopore Technologies (ONT) on the GridION platform. Bioinformatic analysis was performed using the CosmosID platform for taxonomic profiling, antimicrobial resistance gene detection, and genomic relatedness assessment. Conventional microbiological methods identified carbapenem-resistant Pseudomonas aeruginosa (CRPA) in five cases, whereas ONT sequencing detected the blaVIM gene in all seven samples, demonstrating superior diagnostic sensitivity. A highly conserved resistome profile was identified across all investigated cases, including multiple \u03b2-lactamase and aminoglycoside, fluoroquinolone, and polymyxin-associated resistance determinants. Genomic relatedness analysis demonstrated close clustering patterns with minimal genomic variability, suggesting possible circulation of closely related MDR strains. These findings highlight the added value of ONT sequencing in identifying concealed resistance determinants and improving transmission tracking compared with conventional diagnostic approaches. Future investigations involving larger sample sizes and environmental surveillance are needed to further clarify transmission dynamics and potential reservoirs of VIM-producing P. aeruginosa.\n\nID: 42415919\nTitle: Semisynthesis, characterisation, and antibacterial evaluation of a novel lecanoric acid-derived amide library.\nAbstract: The known lichen depside, lecanoric acid (1), was identified as a scaffold of interest for the generation of a unique semisynthetic biodiscovery screening library. Large-scale extraction and isolation on the Australian-sourced lichen Parmotrema tinctorum resulted in the purification of \u22481 g of the desired scaffold 1, along with other known lichen metabolites that included divaricatic acid (2), orcinol (3), orsellinic acid (4), and methyl orsellinate (5). Parallel solution-phase synthesis using amidation chemistry on the abundant scaffold 1 afforded a series of novel amide derivatives 6-13 in high purity (>95%) and low to moderate yields (12-53%). All new semisynthetic compounds were fully characterised following 1D/2D NMR, MS and UV data analysis. Crystalline lecanoric acid was obtained during the chemical investigations of the lichen extract, enabling the first X-ray crystallographic analysis to be undertaken on this depside. Compounds 1-13 were evaluated for antibacterial activity against the human pathogen Pseudomonas aeruginosa using a biofilm inhibition assay. Of the new semisynthetics, amide analogue 12 showed the greatest planktonic cell growth inhibition (13% at 50 \u00b5M), whilst amide analogue 11 was the most active at inhibiting the formation of biofilm (21% at 50 \u00b5M).\n\nID: 42415191\nTitle: Acute gastroenteritis caused by Comamonas testosteroni in a patient with hepatobiliary dysfunction: a case report highlighting diagnostic challenges during the pre-monsoon season in India.\nAbstract: Comamonas testosteroni is a rare, environmental Gram-negative Bacillus increasingly recognised as an emerging opportunistic pathogen. It is often misidentified as a Pseudomonas species in routine laboratories due to overlapping phenotypic characteristics. Although generally of low virulence, it can cause severe infections in patients with underlying hepatobiliary or immunocompromised conditions. We report a case of an 18-year-old male from Karnataka, South India, who presented with fever, vomiting, and watery diarrhoea during the early monsoon showers of May 2025. Laboratory evaluation revealed hepatocellular dysfunction, cholelithiasis, and coagulopathy. Stool culture bluish-green colonies on thiosulfate-citrate-bile salts-sucrose (TCBS) agar, initially resembling those of Pseudomonas. Automated identification using the VITEK-2 Compact system and confirmation at ICMR-NIRBI (Indian Council of Medical Research-National Institute for Research in Bacterial Infections), Kolkata, identified the isolate as Comamonas testosteroni. The organism was sensitive to piperacillin/tazobactam, ceftriaxone, cefoperazone/sulbactam, imipenem, meropenem, amikacin, gentamicin, ciprofloxacin, and trimethoprim/sulfamethoxazole. The patient responded well to ceftriaxone and supportive care. This case underscores the diagnostic challenge of detecting C. testosteroni, particularly during overlapping outbreaks. The inclusion of differential media and careful interpretation of culture results is crucial for accurate identification. Diligent culture reporting helps in strengthening public health surveillance, infection control, and outbreak preparedness in resource-limited settings.\n\nID: 42414423\nTitle: Green synthesis of tetrahydropyridine-3-carboxylate derivatives and evaluation of antimicrobial and antimalarial activities supported by molecular docking, POM studies, and drug-likeness analysis.\nAbstract: A series of novel haloarene-decorated tetrahydropyridine derivatives B(1a-1f) were synthesized via a simple, environmentally benign one-pot multicomponent reaction employing ethanol as a green solvent and [Et\u2083NH][HSO\u2084] as a Br\u00f8nsted acid ionic liquid catalyst. The reaction utilized methyl acetoacetate (1 mmol), substituted aromatic aldehydes (2 mmol), and substituted anilines (2 mmol) at 60\u00a0\u00b0C to afford the desired compounds. All compounds were evaluated for their in vitro antimicrobial activity against three fungal strains (Candida albicans, Aspergillus niger, and Aspergillus clavatus), two Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa), and two Gram-positive bacteria (Staphylococcus aureus and Streptococcus pyogenes), using the serial broth dilution method. Additionally, their antimalarial potential was assessed against chloroquine- and quinine-sensitive 3D7 and multidrug-resistant Dd2 strains of Plasmodium falciparum. Among the synthesized derivatives, compounds B1a, B1b, and B1b exhibited the most potent antimicrobial and antimalarial activities. Molecular docking studies revealed that compound B1f showed the highest binding affinity toward S. aureus nucleoside diphosphate kinase, with a predicted free binding energy of -\u2009913\u00a0kcal/mol. Pharmacological profiling suggested favorable drug-like properties and non-toxic behavior. These findings highlight haloarene-decorated tetrahydropyridine derivatives as promising dual-action candidates with potential to combat both bacterial and malarial infections.\n\nID: 42413479\nTitle: In\u00a0Vitro Efficacy of Quinolones and Carbapenems against Nonfermenting Gram-Negative Bacteria Isolated from Clinical Specimens in a Nepalese Tertiary Care Hospital.\nAbstract: Nonfermenting Gram-negative bacteria (NFGNB) pose a significant public health threat due to multidrug resistance (MDR) mediated by biofilms, efflux pumps, and carbapenemases. This cross-sectional study evaluated the minimum inhibitory concentrations (MICs) of quinolones and carbapenems against the Acinetobacter calcoaceticus-baumannii (ACB) complex and Pseudomonas aeruginosa isolated from clinical specimens at the Nepal Armed Police Force Hospital, Balambu, Kathmandu, Nepal. These NFGNB were isolated and identified using standard microbiological methods. Quinolone- and carbapenem-resistant isolates, screened by disc diffusion, were tested for MICs of quinolones and carbapenems using broth microdilution. Statistical analyses were performed in SPSS v. 17.0. Ninety-two NFGNB were isolated, predominantly from urine (40.2%; 37/92). The MDR proportion was high in P. aeruginosa (85.7% [18/21] versus 80.28% [57/71]). The extensively drug-resistant (XDR) proportion was high in the ACB complex (14.1% [10/71] versus 4.8% [1/21]). The MIC50 in P. aeruginosa against norfloxacin and ofloxacin was \u22658 and \u22650.5 \u00b5g/mL, respectively. The MIC50 against ciprofloxacin in P. aeruginosa was \u22658 \u00b5g/mL, whereas it was \u226532 \u00b5g/mL in the ACB complex. MIC50 against levofloxacin was \u22650.5 \u00b5g/mL in P. aeruginosa, unlike the ACB complex (\u226516 \u00b5g/mL). The MIC50 for meropenem was lower in the ACB complex (\u22654 versus \u22658 \u00b5g/mL) than in P. aeruginosa, whereas both showed similar MIC90 (\u226564 \u00b5g/mL). ACB complex showed higher MIC50 against imipenem (\u22654 \u00b5g/mL) than P. aeruginosa (\u22650.125 \u00b5g/mL). Over three-fourths of the NFGNB infections were caused by the ACB complex, exhibiting high XDR rates and elevated MICs to quinolones and carbapenems, underscoring the need for strengthened antimicrobial stewardship.\n\nID: 42410144\nTitle: Removal and analysis of foodborne-associated pathogens via peptide functionalized nanoparticles.\nAbstract: Foodborne illnesses still remain a major health issue, as the WHO reported 600 million diseases and 420,000 deaths worldwide in 2010. Most of them were caused by pathogens like Campylobacter spp., Salmonella enterica, Escherichia coli, and Listeria monocytogenes. Due to the short shelf life of fresh meat and dairy products, a rapid detection of pathogens in contaminated food products is essential. Since reference methods for microbial food analysis require time-consuming nonselective and selective culturing procedures, the need for more efficient approaches is given. In this study, we employ superparamagnetic iron oxide nanoparticles (SPIONs) functionalized with the peptide KRQGRVEVLYRASWGTV derived from the salivary protein GP-340, to successfully remove different species of food-related microorganisms (Pseudomonas paracarnis, Campylobacter jejuni, Escherichia coli, Enterococcus faecalis, Salmonella enterica, and Listeria monocytogenes) from pure media and homogenates derived from retail meat products. We discovered differences in extraction efficiencies from pure culture ranging from 18% (C. jejuni) to complete extraction (E. faecalis, L. monocytogenes and P. paracarnis) depending on the organism. It was also shown that L. monocytogenes could successfully be removed from co-culture with a high surplus of non-pathogenic P. paracarnis, and also from food matrices. KEY POINTS: \u2022 SPIONCitcan be functionalized with a GP-340 derived peptide (SPIONPep) \u2022 SPIONPep\u00a0can immobilize and remove L. monocytogenes from pure and co-culture with high surplus of non-pathogenic P. paracarnis \u2022 Removal of L. monocytogenes is also possible in complex food matrices.\n\nID: 42405335\nTitle: Antimicrobial resistance in dental unit waterlines: a scoping review of microbial diversity, resistance patterns, and knowledge gaps.\nAbstract: Antimicrobial resistance (AMR) is a growing global health threat, and dental unit waterlines (DUWLs) may contribute to AMR, as DUWLs provide ideal conditions for biofilm development and growth of antimicrobial-resistant microorganisms. However, the microorganisms involved and their resistance patterns in DUWLs remains unclear. This scoping review aimed to map the available evidence on antimicrobial-resistant microorganisms in DUWLs and characterize resistance patterns. We conducted a systematic literature search across the PubMed, Scopus, and Web of Science databases up to March 2026. Studies that reported the isolation of microorganisms from DUWLs and AMR using phenotypic methods and/or genotypic detection of antimicrobial resistance genes (ARGs) were included. Data were extracted and summarized descriptively. A total of 18 studies were included. Most studies analyzed DUWL water samples and reported bacterial isolates, particularly Gram-negative organisms such as Pseudomonas spp. Phenotypic antimicrobial susceptibility testing was performed in 16 studies, with \u03b2-lactams, aminoglycosides, and fluoroquinolones being the most frequently evaluated classes. Ciprofloxacin and gentamicin were the most commonly tested antibiotics. AMR was reported in 15 studies, with frequent resistance to \u03b2-lactams and multidrug resistance. Fungal microorganisms showed reduced susceptibility in biofilms compared to planktonic forms. Genotypic data were limited, and no ARGs were detected in the two studies that assessed them. DUWLs can become sources of antimicrobial-resistant microorganisms. However, the current evidence remains limited due to methodological variability and insufficient genotypic data. Future research should integrate both phenotypic and genotypic approaches, include biofilm-specific analyses, and evaluate the impact of DUWL management and antimicrobial stewardship strategies within a One Health framework. Open Science Framework (OSF) https://doi.org/10.17605/OSF.IO/P3X5D.\n\nID: 42405072\nTitle: Citrus sinensis zest-mediated silver nanoparticles for rapid dye removal and antimicrobial properties.\nAbstract: Growing interest in sustainable and renewable nanotechnology has accelerated the development of green synthesis strategies that are both environmentally friendly and economically viable. In this study, we report a simple, low-cost, and eco-conscious approach for synthesizing silver nanoparticles (AgNPs) using an aqueous zest extract of Citrus sinensis (Cs), which naturally serves as both the reducing and stabilizing agent. The phytochemicals present in the extract-including ascorbic acid, phenolic acids, flavonoids, terpenoids, and polysaccharides-effectively reduce Ag+ ions to stable AgNPs. The formation of AgNPs was confirmed through UV-Vis spectroscopy, revealing a characteristic surface plasmon resonance peak at 420 nm. FESEM imaging demonstrated predominantly spherical nanoparticles with uniform crystallite morphology and rough surface features, while TEM analysis showed an average particle size of approximately 15 \u00b1 5.3 nm. XRD patterns confirmed the polycrystalline nature of the particles with diverse d-spacings, and EDX analysis indicated high purity (93.91% Ag) of the synthesized material. Compared to previously reported green synthesized nanoparticle systems, the biosynthesized AgNPs displayed excellent catalytic activity, achieving dye removal efficiencies of 98.93% (within 18 min) for methyl orange (MO) and 92.15% (within 30 min) for methylene blue (MB) under mild conditions, highlighting the advantage of waste-derived plant extract-mediated synthesis. Moreover, they exhibited strong antibacterial activity, showing notable inhibition against Gram-negative bacteria (E. coli,Pseudomonas spp.,K. pneumoniae, andSalmonella spp.) compared with Gram-positive strains (S. aureus andB. cereus), as assessed by inhibition zone measurements.\n\nID: 42404584\nTitle: Pseudomonas aeruginosa Virulence Bacteriophage Isolated From Inflammatory Mouse Feces Exhibits Bactericidal Activity in Infected Wounds of a Mouse Model.\nAbstract: Recently, bacteriophages have risen as a potent therapy for superbug infections. The mammal gut demonstrates an interesting source of virulence bacteriophages. The gut with inflammation is phage-rich; therefore, we primarily aimed to prove the concept that an inflammatory gut is a possible source of effective phages and to evaluate the efficacy of the candidate phage against Pseudomonas aeruginosa in vitro and in a mouse model of infected wounds. The gut microbiome of cecal ligation and puncture (CLP) sepsis mice, an animal model of inflammation, showed a dominant presence of Podoviruses. CLP bacteriophages (CLP \u03a61-\u03a64), of which the CLP \u03a64 possessed the broadest bactericidal activity (viable bacterial cell reduction in time-kill study) against P. aeruginosa isolates. The CLP \u03a64 specifically killed the Pseudomonas aeruginosa clinical (PACL) strain with two huge burst events. Although the CLP \u03a64 had no effect on ex vivo mouse bone marrow-derived macrophage (BMDM) cytokine gene expression and cytokine production, the CLP \u03a64 attenuated the severity of the P. aeruginosa-infected wound mouse model after treatment. P. aeruginosa PACL exhibited significantly pathogenic characteristics in a mouse model, including excessive bacterial loads (in wounds and internal organs, indicating the systemic infection due to localized infected wound with P. aeruginosa), increased IL-6 cytokine (in serum), upregulated IL-6 expression (in wounds), and immune cell infiltration (in wounds), indicating severe inflammation. In the CLP \u03a64 treatment alone, the wound tissues upregulated IL-10 expression and recruited inflammatory cells. Interestingly, the three-day CLP \u03a64 treatment was adequate to eradicate P. aeruginosa PACL in the wounds and other internal organs. After treatment, the mouse serum cytokine showed a remarkably decreased IL-6. Likewise, IL-6 downregulation and IL-10 upregulation were demonstrated in the treated wounds, suggesting an anti-inflammatory shift. These results demonstrated the effectiveness (bacterial wound and internal organ clearance and cytokine modulation) of the CLP \u03a64 in the P. aeruginosa-infected wound and systemic infection. Finally, the CLP \u03a64 isolation verified a proof of concept that the irritated gut acts as a source of bacteriophages. The gut virome was a promising and interesting source of antimicrobial and immunomodulating bacteriophage.\n\nID: 42402810\nTitle: Detection of OXA-23 Among Carbapenem-Resistant Acinetobacter baumannii Isolated From Intensive Care Units of a Tertiary Care Hospital in Pakistan.\nAbstract: Carbapenem-resistant Acinetobacter baumannii (CRAB) has been designated a top-priority critical pathogen by the World Health Organization, and the CDC has also classified it as a serious and immediate public health threat. The Cross-sectional study was conducted to detect the bla OXA-23 gene among carbapenem-resistant Acinetobacter baumannii isolated from clinical specimens in intensive care units. The study was conducted at the Department of Microbiology, Institute of Pathology and Diagnostic Medicine, Khyber Medical University, from January 2024 to December 2024. Phenotypically confirmed Carbapenem-resistant Acinetobacter baumannii isolates were genotypically verified via blaOXA-51 detection, then screened for blaOXA-23 using polymerase chain reaction, and PCR mapping was done for the upstream insertion of ISAba1. blaOXA-23 gene with an upstream insertion of ISAba1 is detected in all 52 (100%) isolates. ST19 is the most commonly identified ST, accounting for 31 (59.6%), followed by ST2 14 (26.9%) and ST1 7 (13.4%). Consequently, these findings emphasize the implementation of targeted infection control measures and routine surveillance screening within high-risk ICU environments to mitigate further transmission.\n\nID: 42401803\nTitle: A genome-wide association study to identify the genetic loci underlying carbapenem resistance in Acinetobacter baumannii.\nAbstract: Carbapenem-resistant Acinetobacter baumannii (CRAB) presents a significant public health concern, and is recognized as a key contributor to the global antimicrobial resistance (AMR) crisis. This study applied a bacterial genome-wide association study (bGWAS) framework to identify genetic factors beyond the canonical carbapenemase OXA-23, that may contribute to carbapenem resistance. A. baumannii isolates with publicly available whole-genome sequencing (WGS) data and carbapenem-specific antimicrobial susceptibility testing (AST) results were compiled (n\u2009=\u20091,601). Unitigs were extracted from de novo assemblies, and single-nucleotide polymorphisms (SNPs) were called from raw sequence reads mapped to seven selected reference genomes. The unitig- and SNP-based genome-wide association analyses were carried out, including conditional analyses based on the known resistance determinants. Structural analysis was performed for the select candidate mutations. The population was highly clonal and comprised ten lineages, including three predominantly resistant lineages (ST1, ST2, and ST32). Known CRAB-associated loci, including OXA-23, the RND efflux pump regulator AdeL, and OXA-66 variants (Ile129Leu and Leu167Val), were readily identified. Structural analysis of mutations identified outer-membrane proteins as potential candidate loci, however these loci were not supported in the conditional analyses across all reference genomes. The candidate loci supported in the conditional analysis across reference genomes included an amino acid substitution in a LysR-type regulator adjacent to the biofilm-associated operon pgaABCD, and an intergenic substitution located between enzymes involved in LPS remodeling. OXA-23 is the major determinant of carbapenem resistance in A. baumannii. Additional resistance mechanisms may become significant in the absence of OXA-23, including efflux pump regulation (AdeL), membrane permeability (OprD, DcaP), lipopolysaccharide (LPS) transport (PqiB), LPS remodeling (acyltransferase, glycosyltransferase), and biofilm formation (LysR). Integration of the conditional analysis based on known resistance determinants and a multi-reference mapping framework may improve the detection and prioritization of candidate associations.\n\nID: 42401709\nTitle: The weibull model for evaluation of control reliability of carbapenem-sensitive acinetobacter baumannii infections: A case-series study.\nAbstract: Healthcare-associated infections caused by Acinetobacter baumannii remain a major challenge. Reliable tools to evaluate intervention effectiveness are needed. This study applied a parametric survival analysis using the two-parameter Weibull model to assess outcomes among patients with carbapenem-sensitive A. baumannii (CSAB) infections. Data were drawn from a retrospective case-series in a regional hospital in southern Taiwan, including both community and healthcare-associated cases. The intervention combined targeted antimicrobial therapy, intensified environmental disinfection with 0.5% sodium hypochlorite in four ICUs for one month, and an educational campaign. Weibull parameters were estimated via least squares regression to compare survival functions before and after intervention. Results showed improved survival, with scale (\u03b1) increasing from 33.88 to 56.05 days and shape (\u03b2) from 0.894 to 0.948, indicating a more favorable profile. The monthly incidence of healthcare-associated infections decreased from 3.18\u2030 to 2.87\u2030 in the subsequent year, with the most pronounced reduction occurring between months 2 and 4. These findings demonstrate the utility of Weibull modeling in monitoring intervention reliability and suggest that parameter trajectories may serve as early indicators for adjusting strategies. While the intervention appears cost-effective, further analyses incorporating covariates are warranted to strengthen conclusions.\n\nID: 42401059\nTitle: The overlooked risk of horizontal transfer of plasmid-borne antibiotic resistance genes induced by organophosphate esters in aquaculture environments.\nAbstract: In recent years, the emergence of new environmental pollutants has drawn increasing attention to the plasmid-mediated conjugation transfer of antibiotic resistance genes (ARGs) induced by these contaminants. The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized.\n\nID: 42401050\nTitle: Dual role of HCN produced by the endophyte Pseudomonas urmiensis A32 in biocontrol and the defence response of pepper.\nAbstract: Plant-associated Pseudomonas species are widely recognised for their ecological versatility and potential as sustainable biocontrol and plant growth-promoting agents. Among their diverse metabolites, hydrogen cyanide (HCN) is traditionally considered a potent antimicrobial compound, yet its broader role in plant-microbe interactions remains underexplored. This study investigated Pseudomonas urmiensis A32, an endophytic bacterium previously shown to enhance drought tolerance and disease resistance in pepper (Capsicum annuum). Whole-genome analysis revealed genes involved in nutrient acquisition, stress protection, and competitive exclusion, including secondary metabolite clusters for carotenoid and HCN biosynthesis. Wild-type A32 showed increased tolerance to oxidative stress, highlighting a redox-active role for HCN. Seed inoculation with A32 reduced disease symptoms and pathogen load in pepper plants challenged with Xanthomonas euvesicatoria, indicating that HCN contributes not only to direct pathogen antagonism but also to modulation of host immune responses. Biochemical analyses showed decreased activity of antioxidant enzymes and increased phenylalanine ammonia-lyase activity. Gene expression analyses revealed upregulation of PR1 and the antimicrobial peptide gene DEF1, indicating enhanced activation of defence genes. These findings demonstrate that HCN acts as a multifunctional metabolite that fine-tunes the balance between reactive oxygen species detoxification and signalling, and integrates microbial biocontrol with host immune priming. In summary, this work highlights the ecological adaptability of P. urmiensis A32 and its potential as an effective bioinoculant for sustainable crop protection.\n\nID: 42400505\nTitle: Prevalence and genotypic distribution of virulence factor genes and antibiotic susceptibility profiles in clinical Pseudomonas aeruginosa isolates from a public hospital in Nanyang, China.\nAbstract: Pseudomonas aeruginosa remains a critical global health concern, particularly in low- and middle-income countries, owing to its high carriage of diverse virulence factor genes (VFGs) and multidrug resistance. Here, we analyzed the prevalence and genotype distribution of VFGs in P. aeruginosa isolated from Nanyang Central Hospital (NYCH), China, along with their antibiotic susceptibility profiles. The study involved 79 multidrug-resistant (MDR) and 96 non-MDR (nMDR) strains and the following 11 key VFGs (nan1, pilA, aprA, phzS, plcH, toxA, lasB, exoS, exoU, exoT, exoY). Antibiogram profiling showed near-universal resistance to at least one antibiotic class. MDR strains exhibited 23 distinct antibiotic resistance patterns, compared with 13 patterns in nMDR strains. A moderate negative correlation was observed between \u03b2-lactams/\u03b2-lactamase inhibitors and fluoroquinolone resistance. Moreover, statistical analysis revealed that the phzS gene displayed the most significant prevalence difference between MDR and nMDR subgroups (P < 0.001). Finally, 28 distinct genotypes were identified in nMDR isolates, and 26 genotypes appeared in MDR strains. There was a statistically significant correlation found between the presence of genotype XX (r = 0.481, P < 0.001) and genotype XXVIII (r = -0.320, P < 0.001) in two subgroups. Collectively, our findings provide data support for understanding the pathogenic mechanism of local P. aeruginosa, and are of great significance for guiding clinical anti-infection treatment and infection control.IMPORTANCEPseudomonas aeruginosa is an opportunistic pathogen notorious for causing difficult-to-treat infections, particularly among hospitalized patients in resource-limited healthcare settings. This study analyzed clinical isolates from a major hospital in China to investigate the prevalence and genotypic distribution of virulence factor genes (VFGs) and antibiotic susceptibility profiles of P. aeruginosa. Our results showed that multidrug-resistant (MDR) strains displayed more complex and diverse resistance profiles than non-MDR (nMDR) strains. Both MDR and nMDR isolates exhibited high genotypic diversity. Notably, a statistically significant association was observed between genotype XX and genotype XXVIII across the two subgroups. These findings elucidate the molecular basis underlying the variable treatment difficulty of P. aeruginosa infections and offer valuable insights for guiding empirical antibiotic selection. Characterizing local bacterial features, including antibiotic susceptibility profiles and the distribution of clinically relevant virulence factors, may improve understanding of regional resistance trends and support antimicrobial stewardship and infection control efforts.\n\nID: 42397450\nTitle: Molecular characterization and genotypic diversity of extensively drug-resistant Acinetobacter baumannii from endotracheal aspirates in a pediatric intensive care unit in Sulaimani, Iraq.\nAbstract: Extensively drug-resistant (XDR) Acinetobacter baumannii poses a significant threat in pediatric intensive care units (PICUs), particularly in regions with limited surveillance data. This study characterized the bacterial profile of endotracheal aspirate samples from a PICU in Sulaimani, confirmed A. baumannii identification using blaOXA-51 PCR, assessed antimicrobial resistance patterns, and determined genotypic diversity using ERIC-PCR. From August 2023 to March 2025, 100 consecutive Gram-negative isolates were recovered from mechanically ventilated pediatric patients. VITEK2 was used for identification and susceptibility testing. XDR Acinetobacter isolates underwent molecular confirmation via blaOXA-51 PCR, and confirmed isolates were genotyped using ERIC-PCR with UPGMA analysis. Among the 100 total isolates, A. baumannii accounted for 21 isolates alongside Pseudomonas aeruginosa (n\u2009=\u200933) and Klebsiella pneumoniae (n\u2009=\u200920). Given its clinical significance, A. baumannii was selected for further molecular characterization. Overall, 26 isolates exhibited XDR phenotypes, 12 of which were A. baumannii by VITEK2; 10 were confirmed by blaOXA-51 PCR (83.3%). All confirmed isolates were resistant to \u03b2-lactams, carbapenems, aminoglycosides, and fluoroquinolones, while remaining susceptible to colistin. ERIC-PCR revealed one dominant clone (Cluster A, 50%), two minor clusters (20% each), and one singleton (10%), indicating moderate genetic diversity with evidence of sustained clonal circulation. This study provides the first molecular epidemiological characterization of XDR A. baumannii in an Iraqi PICU, revealing clonal persistence of a successful epidemic strain and critical gaps in phenotypic identification. These findings emphasize the need for routine molecular surveillance, targeted infection control, and antimicrobial stewardship in resource-limited settings.\n\nID: 42397081\nTitle: Femtosecond-Laser Nanocavitation Regenerates SERS-Active Plasmonic Nanogaps for Longitudinal Molecular Sensing at Biointerfaces.\nAbstract: Longitudinal, long-term molecular monitoring is critical for personalized medicine, yet protein adsorption in biofluids rapidly fouls bio-interfaced sensors and restricts analyte access to sensing regions. Despite advances in antifouling coatings and regeneration strategies, repeated restoration of surface-enhanced Raman spectroscopy (SERS) sensitivity in static, protein-rich media remains difficult without degrading nanogap integrity, limiting longitudinal sensing. This work introduces a regenerative molecular sensor based on multiresonant plasmonic nanoprotruding meshes (MPNMs) that co-localizes SERS sensing and nanocavitation-based actuation within nanogaps anchored on a biocompatible polymeric mesh. The nanogaps are engineered to support an electric-dipole resonance for SERS enhancement and a magnetic-dipole resonance for photothermal conversion, enabling femtosecond-laser-triggered nanocavitation within SERS-active nanogaps. Upon femtosecond-laser irradiation, collapse of vapor nanobubbles (\u2248200\u00a0ns lifetime) generates thermomechanical forces that detach and displace foulants with micron-scale precision to regenerate the nanogaps while preserving nanomorphology and optical performance. In undiluted human serum, regeneration restores detection limit for the\u00a0Pseudomonas aeruginosa\u00a0virulence factor pyocyanin from 2.0\u00a0\u00b5m to a clinically relevant 3.9\u00a0nm after 24\u00a0h of fouling. Repeated regeneration cycles enable spatiotemporal profiling of dynamic molecular signatures from\u00a0P. aeruginosa\u00a0biofilms in wound models over 24\u00a0h, establishing a self-regenerating platform for longitudinal molecular monitoring in protein-rich biosystems.\n\nID: 42396178\nTitle: Low concentrations of tetrasodium EDTA cause significant killing of biofilm-associated Pseudomonas aeruginosa in high-validity models of chronic wound and cystic fibrosis lung infections - but not in a model of endotracheal tube colonization.\nAbstract: Pseudomonas aeruginosa is a pathogen notorious for its antimicrobial resistance and is currently classified as a high-priority pathogen for which new drugs are needed. Tetrasodium EDTA (tEDTA) is one of the new antimicrobial compounds that have been shown to have good antibacterial and antibiofilm efficacy against P. aeruginosa. Due to the diversity and highly drug-tolerant nature of P. aeruginosa biofilms in different infection environments, it is important to carry out pre-clinical testing of new antibiofilm agents against this pathogen in media and models that accurately mimic diverse infection environments. In this study, we used different high-validity media and biofilm models that mimic chronic wounds, endotracheal tubes and cystic fibrosis lung infections to assess the efficacy of tEDTA against P. aeruginosa biofilms. We report that different infection environments influence the susceptibility of both planktonic and biofilm forms of P. aeruginosa to tEDTA. The highest tolerance to tEDTA was observed in the media and biofilm model that mimics the endotracheal tube environment. In conclusion, we show that although different infection environments influence the efficacy of tEDTA against P. aeruginosa biofilms, it has good potential for use as an alternative antimicrobial in treating P. aeruginosa-associated biofilm infections.\n\nID: 42393552\nTitle: Clinical characteristics, causative organisms, and antimicrobial resistance profiles of hospital-acquired invasive gram-negative bacterial infections at a tertiary-care center in Saudi Arabia: a five-year retrospective cohort study (2020-2024).\nAbstract: Hospital-acquired gram-negative bacterial (HA-GNB) infections are a leading cause of nosocomial morbidity and mortality, yet local epidemiological data to guide empirical therapy remain limited. We conducted a retrospective cohort study of 377 adult patients with culture-confirmed invasive gram-negative infection acquired\u2009\u2265\u200948\u00a0h after admission to King Abdulaziz Medical City (KAMC), Jeddah, Saudi Arabia (2020-2024). Demographics, comorbidities, infection type, microbiology, susceptibility, complications, and outcomes were analyzed using chi-square/Fisher's exact tests and t-tests/Mann-Whitney U tests; multivariable logistic regression was used to identify independent predictors of multidrug-resistant (MDR) infection and in-hospital mortality. Infection types were classified according to U.S. Centers for Disease Control and Prevention / National Healthcare Safety Network (CDC/NHSN) surveillance definitions. Mean age was 64.6\u2009\u00b1\u200917.7 years (59.4% male). Hypertension (61.0%), diabetes (54.6%), and cardiovascular disease (40.8%) were the commonest comorbidities. Pneumonia predominated (47.1%), followed by bloodstream infection (33.0%), surgical-site infection (15.7%), and ventilator-associated pneumonia (9.6%). Klebsiella pneumoniae (41.9%), Pseudomonas aeruginosa (34.0%), and Escherichia coli (15.4%) were the predominant pathogens. Resistance was highest for ciprofloxacin (44.4%), ceftazidime (40.2%), and cefepime (39.9%), and 34.3% for meropenem. Overall morbidity was 68.6% and mortality 39.9%. Mortality was significantly higher in patients with cardiovascular disease (48.8% vs. 34.3%, p\u2009=\u20090.011), hypertension (45.4% vs. 31.5%, p\u2009=\u20090.015), and COPD (100.0% vs. 39.2%, p\u2009=\u20090.025). Diabetes was strongly associated with multidrug-resistant infection (OR 3.60, 95% CI 1.44-9.04; p\u2009=\u20090.004) and remained an independent predictor in multivariable logistic regression adjusting for age, sex, cardiovascular disease, and pneumonia (adjusted OR 2.82, 95% CI 1.11-7.17). HA-GNB infections at this Saudi tertiary center are dominated by K. pneumoniae and P. aeruginosa, carry a roughly two-in-five case fatality, and show worrying resistance to commonly used empirical agents. Within the constraints of a single-center, retrospective design, these findings support local antibiogram-informed review of empirical protocols, continued antimicrobial stewardship, and heightened infection-control attention to high-risk subgroups, particularly patients with diabetes and cardiopulmonary comorbidities; confirmation in prospective, multi-center studies is warranted.\n\nID: 42391897\nTitle: Bacteriostatic mechanisms of CO2 against high-oxygen packaged meat-borne Pseudomonas fragi during chilled storage: Membrane physiological and microstructural changes.\nAbstract: The CO2 inside high-oxygen modified atmosphere packaging (HiOx-MAP) greatly retards the predominant Pseudomonas fragi (P. fragi) growth in chilled meat, whereas the CO2-regulated mechanism on P. fragi cell membrane properties is still unclear. This study investigated the influences of CO2 on both type and wild-type P. fragi growth and cell membrane characteristics during the chilled storage of HiOx-MAP (TMAP\u00a0=\u00a050% O2/40% CO2/10% N2; CMAP\u00a0=\u00a050% O2/50% N2). Compared to CMAP, TMAP significantly reduced P. fragi counts by limiting its motility and disturbing cell membrane structure, composition and function, without causing membrane rupture. CO2 weakened P. fragi membrane function by inducing phospholipid perturbations, but promoted intracellular adenosine triphosphate production as a stress response. Although both packaged P. fragi membrane fluidity and permeability first decreased then increased during storage, a higher (P\u00a0<\u00a00.05) membrane fluidity and permeability was observed in TMAP P. fragi than in CMAP P. fragi over time, indicating P. fragi gradually adapted to a high-CO2 environment. The CO2-elevated ratio of unsaturated to saturated fatty acids significantly increased P. fragi membrane fluidity, and thus enhanced its membrane permeability. This study offers a new mechanistic basis for the CO2-bacteriostatic action in meat preservation targeted at bacterial cell membranes.\n\nID: 42390567\nTitle: Disrupting virulence: in silico discovery of MexL inhibitors to block pyocyanin biosynthesis in Pseudomonas aeruginosa.\nAbstract: Pseudomonas aeruginosa is an opportunistic pathogen known for its intrinsic antibiotic resistance and ability to form biofilms, primarily regulated by the redox-active compound, pyocyanin. The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM. Targeting MexL may serve as a novel anti-virulence strategy by suppressing pyocyanin production and attenuating pathogenicity of P. aeruginosa. This study aimed to identify potential inhibitors of MexL using in silico approaches to disrupt its regulatory function and reduce pyocyanin synthesis. The findings suggest that the selected compounds could serve as effective inhibitors of MexL, offering a promising strategy to suppress pyocyanin biosynthesis and reduce P. aeruginosa virulence. For this purpose, molecular docking was conducted between the binding pocket of the MexL protein and compounds selected based on pharmacokinetic properties from the FooDB, NPASS, and LOTUS databases. Furthermore, molecular dynamics simulations were performed on the selected MexL-ligand complexes to evaluate the stability of the protein-ligand complex within a simulated solvated environment under defined conditions. The virtual screening by molecular docking identified four top-scoring ligands FDB000380, LTS0012415, and NPC253096 and ZINC14780782 with binding energies of -8.6, -7.5, -7.1, and -8.8\u00a0kcal/mol respectively, showing strong affinities toward the MexL binding pocket. These ligands demonstrated key molecular interactions with residues critical for regulatory function of MexL protein. Molecular dynamics simulations (300\u00a0ns) of the three lead MexL-ligand complexes (FDB000380, LTS0012415, and NPC253096) revealed exceptional structural stability, with low backbone RMSD values (0.240-0.309\u00a0nm), minimal residue fluctuations, stable radius of gyration, and consistent solvent-accessible surface area profiles. Persistent protein-ligand hydrogen bond networks (occupancy 72.1-100%) confirmed stable polar interactions throughout the trajectories. MM-GBSA and MM-PBSA binding free energy calculations demonstrated superior affinities over the endogenous ligand pyocyanin (\u0394G\u2009=\u2009\u2009-\u200915.30 to\u2009-\u200921.75\u00a0kcal/mol versus\u2009-\u200912.57\u00a0kcal/mol). Principal component analysis further revealed restricted conformational dynamics and compound-specific free energy landscapes, collectively supporting these three compounds as thermodynamically stable lead inhibitors of MexL-mediated pyocyanin biosynthesis in Pseudomonas aeruginosa.\n\nID: 42390516\nTitle: Prevalence and Antimicrobial Resistance of Non fermenting Gram-negative Bacilli Isolated from Blood Culture Samples in a Tertiary Care Hospital.\nAbstract: Non-fermenting Gram-negative bacilli (NFGNB) are emerging as a significant cause of bloodstream infections (BSIs), a major concern of morbidity and mortality worldwide. The high intrinsic resistance of NFGNB to antimicrobial compounds makes treatment of BSI difficult and expensive. This study aimed to determine the prevalence of NFGNB and the antimicrobial susceptibility pattern of the isolates. A total of 1230 blood culture samples were received in the department of microbiology during the study period of 3 months, which were processed by standard microbiological procedures. Antimicrobial susceptibility tests were performed using Clinical and Laboratory Standards Institute (CLSI) guidelines. Out of 255 (20.73%) positive blood culture samples, 105 (8.5%) Gram-negative bacilli were isolated, of which 41 (3.33%) NFGNB were identified. The most common isolate identified is Pseudomonas aeruginosa (21), followed by Acinetobacter spp. (20). A higher percentage of antibiotic resistance was seen for Acinetobacte r spp. and even higher antibiotics like ceftazidime (87.5%) and gentamicin (92.5%). This study will help us start empirical treatment and implement proper hospital infection control measures.\n\nID: 42419610\nTitle: Nanomedicine strategies against multidrug-resistant Acinetobacter baumannii: Delivery, biofilm disruption, and translational considerations.\nAbstract: Acinetobacter baumannii has become a high-priority global problem because it causes hospital-acquired infections and ventilator-associated pneumonia, and multidrug resistance, environmental survivability, and biofilm formation severely restrict therapeutic choices. Antimicrobial nanomedicine has become a major focus as a translational approach. This review critically explores nanotechnology-based interventions for A. baumannii. Multimodal antibacterial and antibiofilm activities have been demonstrated in inorganic nanoparticles, such as silver, gold, and copper-based systems, with an emphasis on their translational therapeutic potential and nano-bio interactions. Polymer- and lipid-based nanocarriers focus on optimising pharmacokinetics, controlled release, and targeted delivery, supporting improved bioavailability and site-specific exposure. Carbon nanomaterials offer alternative antibacterial mechanisms but raise concerns regarding biodegradability and safety. Overall, antimicrobial nanomedicine can be considered an exposure- and delivery-focused system with significant potential for treating persistent drug-resistant A. baumannii infections, highlighting the translational, toxicological, and regulatory challenges relevant to clinical adoption.\n\nID: 42419187\nTitle: Computational framework integrating subtractive proteomics and structural bioinformatics to nominate candidate fungicide targets in Puccinia graminis f. sp. tritici.\nAbstract: Puccinia graminis f. sp. tritici, the causal agent of wheat stem rust, continues to threaten global wheat production through recurring outbreaks and the erosion of host resistance and chemical control efficacy. This study aimed to identify candidate protein targets for fungicide development in P. graminis f. sp. tritici. An integrated subtractive proteomics pipeline was then applied, combining essentiality screening, pathway analysis, structural modeling, and exploratory molecular docking. A stringent filtering strategy excluding proteins homologous to Triticum aestivum, Homo sapiens, and beneficial microbes (Bacillus subtilis, Pseudomonas fluorescens, and Trichoderma harzianum) was applied, thereby maximizing selectivity while minimizing potential off-target ecological effects. From 36,348 proteins, four putative targets were identified: two \u03b2-glucan synthesis-associated KRE6 homologs, a cell wall \u03b1-1,3-glucan synthase (AGS1), and a Major Facilitator Superfamily (MFS) transporter. Guided by intrinsic disorder analysis, AlphaFold2 was used to generate high-quality 3D structural models of the prioritized targets. Network-based functional analysis linked these proteins to core cellular processes, while underscoring that their essentiality in P. graminis f. sp. tritici remains experimentally unconfirmed. Molecular docking with the antifungal agent poacic acid and the nucleotide sugar UDP-glucose suggested potential binding interactions within the predicted cavities. These exploratory simulations present preliminary evidence for plausible small-molecule binding pockets in the selected candidate targets. Collectively, this work provides a multi-layered computational framework for nominating and structurally characterizing candidate targets in wheat stem rust and generates testable hypotheses for future experimental work.\n\nID: 42417706\nTitle: Germination and Polishing Reshape Microbial Communities in Japonica and Indica Rice.\nAbstract: Germination is a process used to improve the nutritional quality of rice. However, its impact on rice microbiomes remains poorly understood. This study evaluated the microbiota of two rice ecotypes, low-amylose (Mochi) and high-amylose (BRS Formoso), after germination and polishing using 16S rRNA and ITS amplicon sequencing. Bacterial alpha diversity was highest in commercial brown rice (Shannon index 3.21) and lowest in commercial polished rice (1.50). Beta diversity indicated that germination exerted a similar effect on bacterial community composition in both ecotypes. Principal Coordinate Analysis suggested that polishing did not markedly influence microbiome composition relative to germination. The microbial profiles of Mochi and BRS Formoso were dominated by Pantoea, Pseudomonas, Rhizopus, and Moesziomyces. Overall, germination strongly influenced bacterial and fungal communities, emerging as the main factor shaping microbial structure and dynamics. These findings provide new insights into how processing affects the rice microbiome, with implications for food quality and safety.\n\nID: 42414953\nTitle: Dual antimicrobial and anticancer functions of artemisinin-loaded PEG400-oa nanoparticles: synergistic activity with ciprofloxacin and mechanistic insights from molecular docking.\nAbstract: Artemisinin, a bioactive compound from Artemisia annua with potent antioxidant, antimicrobial and anticancer properties, faces limited clinical utility due to poor solubility and low bioavailability. Given the rising prevalence of multidrug-resistant (MDR) Pseudomonas aeruginosa alternative therapeutic strategies are essential. This study synthesized and characterized artemisinin-loaded micelle/liposome nanoparticles (Art/PEG400-OA NPs) and evaluated their antibacterial, antibiofilm, and anticancer efficacy. Artemisinin was successfully encapsulated within PEG400-OA NPs and characterized via FT-IR, FE-SEM, TEM, TGA, and zeta potential measurements. The nanoparticles exhibited uniform morphology, particle sizes of 40.8\u00a0nm (TEM) and 149.8\u00a0nm (FE-SEM), high encapsulation efficiency (92.14%), and strong thermal and colloidal stability. Synergistic and partial synergistic interactions between Art/PEG400-OA NPs and ciprofloxacin were observed in MDR bacterial samples, significantly inhibiting biofilm formation. Quantitative RT-PCR analysis revealed the downregulation of efflux pump genes (mexA, mexB, mexX, mexY, oprM) and biofilm-associated genes (algD, pelA) following combination therapy. In AGS gastric cancer cells, Art/PEG400-OA NPs induced dose- and time-dependent cytotoxicity (IC\u2085\u2080: 67.75, 62.25 and 54.98\u00a0\u00b5g/mL at 24, 48 and 72\u00a0h), increased apoptosis (31.76% \u00b1 4.2%), and reduced wound-healing migration (56.65% \u00b1 4.26%). Expression analysis demonstrated upregulation of tumor-suppressive miR-34a, and downregulation of its targets (CTNNB1, TGFB1, MMP2 and MMP9). Conversely, miR-181a was downregulated, leading to the upregulation of apoptotic target genes (TP53, CASP8, CASP9). Molecular docking supported strong artemisinin binding to key bacterial and oncogenic proteins. Overall, Art/PEG400-OA nanoparticles represent a potent dual-action nanotherapeutic platform against antibiotic-resistant infections and gastric cancer.\n\nID: 42414399\nTitle: Pangenome-guided immunoinformatics design and in silico characterization of a multi-epitope vaccine candidate against Acinetobacter baumannii with nanoparticle assembly potential.\nAbstract: Acinetobacter baumannii is a critical multidrug-resistant pathogen causing severe healthcare infections with high mortality, yet no licensed vaccine exists. This study aims to identify universally conserved surface antigens through pangenome analysis, predict immunogenic epitopes using integrated machine learning, and computationally design and in silico characterize a self-assembling nanoparticle vaccine with dual adjuvants. A computational framework integrating pangenome analysis of 712 complete genomes, epitope prediction, and structural vaccinology was employed to design a multi-epitope nanoparticle vaccine candidate for experimental evaluation. Pangenome analysis identified 3894 core genes with 42 outer membrane proteins, prioritizing OmpA, BamA, and OmpW as antigen targets. Protein language models predicted conformational B-cell epitopes, while NetMHCpan-4.2 predicted T-cell epitopes across 125 HLA alleles. The final construct (AB-VAX-01, 289 amino acids) incorporates 15 epitopes fused with dual adjuvants (RS09 TLR4 and cGAMP STING agonists) and a foldon domain for nanoparticle assembly. Microsecond molecular dynamics simulations with replicates demonstrated stability with TLR4 and STING. Conservation analysis across all 712 genomes showed 96.2-100% epitope identity. Immune simulations predicted Th1-biased responses with 94.2% global population coverage. In silico cloning confirmed favorable codon adaptation parameters. This in silico characterized vaccine construct represents a promising candidate requiring experimental validation against A. baumannii infections.\n\nID: 42412991\nTitle: Exploring the Antibacterial Potential of Bis-MPA Dendrimers Bearing Cu(II) and Zn(II) Complexes.\nAbstract: The rise of multidrug-resistant bacteria demands antimicrobial agents that act rapidly and durably. In this work, we aim to develop biodegradable and biocompatible antimicrobial systems by combining the versatile bis-MPA dendritic skeleton with the antibacterial properties of Zn(II) and Cu(II) complexes. The resulting metallodendrimers were synthesized using scalable bis-MPA scaffolds and systematically evaluated for antibacterial activity, cytotoxicity, resistance development and bactericidal kinetics. The dendrimers exhibit broad-spectrum antibacterial efficacy at low micromolar concentrations, with minimum inhibitory concentration values as low as 0.4 \u03bcM, while maintaining over 70% viability in fibroblasts and keratinocytes and showing no hemolytic activity toward erythrocytes at bactericidal doses. Second-generation Cu(II) and Zn(II) bis-MPA dendrimers eradicated Bacillus subtilis within 24 h and suppressed Pseudomonas aeruginosa within 4 h, without detectable resistance emergence and with superior activity to ciprofloxacin in the latter. Overall, the combination of rapid antimicrobial action, favorable cytotoxicity profiles, strain-dependent resistance behavior, and scaffold versatility highlights bis-MPA metallodendrimers as promising candidates for next-generation antimicrobial therapies.\n\nID: 42405543\nTitle: Metagenomic Analysis of Thoracic Empyema Etiology Through Next-Generation Sequencing Enhances Conventional Culture Techniques.\nAbstract: This study aimed to analyze the microbiome of thoracic empyema using metagenomic methods and compare the results with conventional culture methods to increase diagnostic accuracy and enhance antibiotic therapy. This study involved 30 patients with thoracic empyema from hospitals in Riau Province, Indonesia. Pleural fluid samples were collected for culture analysis and identification using the Vitek 2 compact system and metagenomic analysis. Patient clinical data were also collected. Culture methods showed a 40.0% positive rate, with Gram-negative bacteria (Klebsiella pneumoniae and Pseudomonas aeruginosa) predominating. Metagenomics showed a 56.7% positive rate, identifying a more diverse microbiome, including fungi (29.4% abundance), other Gram-negative bacteria (26.5%), and anaerobic bacteria (22.5%). Comparison of the two methods showed 36.7% complete agreement and 23.3% partial agreement, with 40% disagreement, with a Kappa coefficient of 0.416 and P-value of 0.016 (P<0.050). Metagenomic NGS offers significant advantages in detecting the microbiome of thoracic empyema, particularly fungi and anaerobic bacteria, which are often missed by conventional culture methods. This has the potential to improve diagnostic accuracy and optimize antibiotic therapy. Further research with larger sample sizes is needed.\n\nID: 42405256\nTitle: Dietary prebiotics and synbiotics modulate gut microbiota and improve growth performance of Mexican pike silverside Chirostoma estor.\nAbstract: Aquaculture is the fastest-growing food production sector worldwide and is vital for a sustainable animal protein supply. However, optimizing fish performance in captivity remains a major challenge, requiring functional diets that support a healthy holobiont. This study evaluated the effects of balanced experimental diets supplemented with inulin or yeast cell wall (prebiotics), Lactobacillus acidophilus (probiotic), or their combination (synbiotics) on juvenile pike silverside (Chirostoma estor). Growth performance was monitored, and gut microbiota composition was characterized by 16S rRNA gene metabarcoding. Synbiotic and yeast cell wall supplementation significantly improved growth parameters, including weight gain, final body weight, and specific growth rate, compared to the control. Microbiota profiling revealed a core community of nine genera (Bacillus, Citrobacter, Cutibacterium, Lactobacillus, Pseudomonas, Spiroplasma, Stenotrophomonas, Streptococcus, and Thermogemmatispora), with each treatment inducing distinct shifts in bacterial composition. Candidate probiotic taxa, including Lactobacillus spp., were also identified as part of the gut microbial response to dietary treatments. Functional predictions further indicated an enrichment of bacterial biosynthetic pathways in synbiotic and yeast cell wall treatments, aligning with the observed improvements in growth and feed efficiency. These findings indicated that yeast cell wall and synbiotic supplementation modulated gut microbial composition and were associated with improved growth performance in C.\u00a0 estor, underscoring the role of microbiome-targeted nutrition in this species.\n\nID: 42404764\nTitle: Comparative analysis of treatment outcomes and risk factors associated with different combination antimicrobial regimens in patients with multidrug-resistant Acinetobacter baumannii pneumonia.\nAbstract: Multidrug-resistant Acinetobacter baumannii (MDRAB) pneumonia is a major cause of mortality in hospital-acquired infections due to extensive drug resistance and limited therapeutic options. Optimizing treatment and identifying mortality-related factors are urgently needed. To compare the efficacy of different antibacterial regimens in MDRAB pneumonia and determine independent risk factors for 28-day all-cause mortality. This single-center retrospective cohort study included 142 MDRAB pneumonia patients from February 2022 to February 2025. Patients were divided into three groups: Group A, sulbactam-containing combinations (n = 63); Group B, polymyxins + tigecycline (n = 45); Group C, other regimens (n = 34). Outcomes included bacterial resistance patterns, 28-day mortality, dynamic PCT and CRP levels, APACHE II and SOFA scores, and lymphocyte subsets. Multivariate logistic regression identified mortality predictors. Group A showed the lowest resistance to cefoperazone/sulbactam (30.16%) and the highest sensitivity (71.43%, both P< 0.05). Group B had the highest tigecycline resistance (31.11%). The 28-day mortality rates were 39.68% (A), 60.00% (B), and 64.71% (C) (P\u00a0=\u00a00.028). Independent mortality predictors were APACHE II, SOFA, and CD4+/CD8+ ratio (all P< 0.01). On day 7, Group A had the lowest PCT, while Group C showed the smallest declines in PCT and CRP. Group A exhibited the highest CD4+/CD8+ ratio. Sulbactam-based combination therapy was associated with improved pathogen clearance and survival in this retrospective cohort. Mortality is closely linked to initial disease severity and early organ dysfunction. Dynamic changes in PCT and CD4+/CD8+ ratio have significant prognostic value.\n\nID: 42402928\nTitle: Assessment of the enhanced antibacterial activity of snail mucus, thymol, and ferulic acid in a rat model of burn wounds infected with Staphylococcus aureus and Pseudomonas aeruginosa.\nAbstract: To develop and evaluate a novel topical formulation - comprising snail mucus, thymol, and ferulic acid (STF) - for treating wounds infected with multidrug-resistant bacteria, and to compare its therapeutic efficacy against silver sulfadiazine. The in vitro antimicrobial properties of STF were analyzed using checkerboard assays to determine the fractional inhibitory concentration (FIC) index. The cytotoxicity of STF was determined using the MTT viability assay using L929 fibroblasts. The in vivo efficacy of STF was assessed using a rat excisional wound model, and wound closure rates were measured at 14\u2009days post-infection. STF showed an additive interaction in the in vitro model (FIC index: 0.717-0.936) and possessed low cytotoxicity (IC50: 705.4\u2009\u00b5g/mL) compared to the individual compounds. In the in vivo model, the group treated with STF showed significantly faster wound healing and decreased inflammation compared to all other groups, including the silver sulfadiazine group. The combination of snail mucus in STF is a highly effective remedy for infected wounds, providing complementary benefits in vivo by coupling antimicrobial activity with pro-regenerative functions, and demonstrates superiority over silver sulfadiazine.\n\nID: 42402284\nTitle: Integrated metagenomic and metaproteomic insights into current-carrying-coil magnetic field enhanced synergistic methanogenic system and antibiotic resistance gene reduction in cow manure anaerobic digestion.\nAbstract: Anaerobic digestion (AD) is a sustainable strategy for valorizing cow manure (CM). However, the high ammonia (NH3) concentration and low biodegradability of CM limit hydrolysis and methane production. This study investigated the application of a current-carrying-coil-based magnetic field (CCC-MF) to AD of CM. The CCC-MF digesters showed higher soluble chemical oxygen demand and attained 16.59\u00a0% higher ammonium nitrogen reduction, contributing to a 37.50\u00a0% higher average methane yield than the control. Further, CCC-MF digesters showed higher enzyme activities (alkaline protease\u00a0+\u00a030\u00a0%, acetate kinase\u00a0+\u00a022\u00a0% and hydrazine dehydrogenase\u00a0+\u00a026\u00a0%) and increased microbial metabolic indices (dehydrogenase activity\u00a0+\u00a017\u00a0% and electron transport system activity\u00a0+\u00a010\u00a0%) than the control. Metagenomics analysis revealed that abundances of the bacterial genera Mesotoga, Aminobacterium, Xiashengella, unclassified Candidatus Cloacimonadota, Advenella, Pseudomonas, and Comamonas increased, whereas the acetoclastic methanogen Methanothrix decreased by 2.58\u00a0%, accompanied by 2.07- and 1.64-fold increases in hydrogenotrophic methanogens Methanospirillum and Methanobacterium, respectively, in CCC-MF digesters. The abundance of nitrogen dissimilation and assimilation genes NirK, NorB, NarB, NapA, nmo, and GLT1 were enhanced by 1.14, 1.04, 2.30, 1.32, 1.17, and 1.29-fold in CCC-MF digesters compared to the control. Moreover, metaproteomics revealed higher up-regulated differentially expressed proteins in NH3 reduction-related amino acid metabolism pathways in CCC-MF digester compared to control. Additionally, reduced abundances of bacitracin, polymyxin, sulfonamide, and multidrug antibiotic resistance (MAR) gene types were observed in the CCC-MF digesters. The findings suggest that applying CCC-MF may be associated with higher methane production and ammonium reduction, potentially linked to a more favorable synergistic methanogenic system and nitrogen transformation pathways.\n\nID: 42398872\nTitle: AroC as a key virulence factor and live-attenuated vaccine target in Pseudomonas plecoglossicida.\nAbstract: Pseudomonas plecoglossicida is a major etiological agent of visceral white-spot disease in diverse aquaculture species. Chorismate synthase (AroC), a key enzyme in the aromatic amino acid biosynthetic pathway, is essential for central metabolism and has been implicated in bacterial virulence. In this study, an aroC deletion mutant (\u0394aroC) and a complemented strain (C\u0394aroC) were constructed to investigate the role of AroC in virulence regulation and to evaluate its potential as a live-attenuated vaccine candidate. Compared with the wild-type (WT) strain, \u0394aroC exhibited significantly reduced growth, motility, hemolytic activity, and biofilm formation. In infection experiments, \u0394aroC showed markedly attenuated virulence, resulting in 90% host survival. In a goldfish vaccination-challenge model, immunization with \u0394aroC conferred moderate protective efficacy, with a relative percent survival (RPS) of 62%. Transcriptomic analysis revealed that aroC deletion led to the downregulation of genes involved in amino acid metabolism, ABC transporters, and quorum sensing pathways. These results suggest that AroC contributes to pathogenicity by coordinating metabolic processes and environmental adaptation. Together, our findings identify AroC as an important virulence determinant in P. plecoglossicida and suggest that \u0394aroC is a promising live-attenuated vaccine candidate that warrants further validation in the natural host.\n\nID: 42398603\nTitle: Targeting the FtsH protease unmasks a universal vulnerability to antimicrobial peptoids.\nAbstract: The rapid rise of multidrug-resistant (MDR) bacteria highlights the need for new antimicrobial agents beyond traditional mechanisms. Synthetic peptoids are promising therapeutics. Mechanistic studies reveal peptoids kill bacteria not by damaging membranes but by causing widespread macromolecular aggregation of intracellular proteins and nucleic acids. This proteotoxic stress challenges the bacterial ATP-dependent protease system, though precise defense pathways remain elusive. Understanding how bacteria counter this stress is essential for developing effective combination treatments. We showed that FtsH is the key protective mechanism, as only \u0394ftsH drives a 16-fold sensitization, identifying it as the bottleneck for survival under peptoid stress. Its protective role fundamentally depends on bacterial energy metabolism. Disabling FtsH increases susceptibility in Pseudomonas aeruginosa (P. aeruginosa), suggesting that FtsH represents a shared vulnerability across tested peptoid scaffolds. This uncovers a common vulnerability within the proteostasis network of MDR pathogens. FtsH is intrinsically less active under low-energy conditions typical of antibiotic-tolerant persister cells. This metabolic repression renders persisters uniquely susceptible to peptoid-induced proteotoxic stress. Combining the peptoid (TM5) with an FtsH inhibitor (carbonyl cyanide m-chlorophenyl hydrazone) or an energy-depleting compound is highly effective, providing a mechanism-driven strategy to overcome persister cell's drug tolerance.\n\nID: 42397361\nTitle: [Efficacy of Topical Medications in Mastoid Cavity Care Following Canal Wall Down Mastoidectomy. (A Retrospective Cohort Study)].\nAbstract: Postoperative management of mastoid cavities after canal wall down (CWD) mastoidectomy remains challenging due to persistent otorrhea, infection, and delayed healing. Topical medications are widely used, but comparative data on their efficacy are limited. To evaluate the outcomes of different topical medications in patients with mastoid cavities following CWD mastoidectomy. A retrospective cohort study of 128 patients treated between 2015-2022. Groups included quinolone antibiotic drops (n=45), antiseptic agents (n=38), antifungal solutions (n=25), and combination therapy (n=20). Primary outcomes were resolution of otorrhea and epithelialization time. Secondary outcomes included complications and microbial resistance. Combination therapy (quinolone antibiotic + antiseptic) achieved the highest otorrhea resolution rate (95%) and shortest epithelialization time (6.2\u00b11.8 weeks). Antifungal agents had the lowest efficacy (68% resolution). Pseudomonas aeruginosa (32%) and Staphylococcus aureus (24%) were predominant pathogens, with quinolone antibiotic resistance observed in 18%. Combination topical therapy optimizes mastoid cavity healing, while antifungal agents should be reserved for confirmed fungal infections.

anti-MRSA activity with low toxicity and high therapeutic potential.\nAbstract: The emergence and rapid spread of methicillin-resistant Staphylococcus aureus (MRSA) pose a significant threat to public health, underscoring the urgent need for the development of effective antibacterial agents. Bacteriocins, as highly promising antibacterial candidates, have garnered considerable attention in the scientific community. In this study, a novel bacteriocin, designated Pacin, was successfully purified from the fermentation broth of Pseudomonas strain 166. Pacin exhibited potent antibacterial activity against MRSA, with minimum inhibitory concentration (MIC) of 0.25 \u00b5g/mL. At concentrations up to 512 \u00b5g/mL, Pacin showed no significant cytotoxicity toward Vero or F81 cells and induced negligible hemolysis of rabbit red blood cells, with a hemolytic rate below 0.04%. In a murine model of MRSA-infected wounds, Pacin significantly promoted wound healing. In a peritonitis-sepsis model, mice treated with Pacin displayed no organ abnormalities and a marked reduction in bacterial burden. Further analyses, including cell membrane integrity assays, cell wall integrity assessments, scanning electron microscopy, and transmission electron microscopy, demonstrated that Pacin exerts its antibacterial effect by disrupting the bacterial cell membrane and cell wall structures, thereby inhibiting bacterial survival. Collectively, these findings establish Pacin as a highly effective antibiotic alternative for combating MRSA infections, with substantial potential for clinical application. This study introduces Pacin, a novel bacteriocin isolated from Pseudomonas strain 166, as a potent therapeutic agent against MRSA. With the global rise of antibiotic resistance threatening public health, there is an urgent need for safe and effective alternatives to conventional drugs. Pacin demonstrates exceptional activity by effectively killing MRSA through membrane and cell wall disruption while showing no toxicity to mammalian cells or zebrafish embryos. Its stability under varying environmental conditions and shows efficacy in treating severe skin infections and sepsis in animal models highlight its clinical potential. These findings position Pacin as a promising next-generation antimicrobial agent capable of addressing critical gaps in current treatment strategies for life-threatening resistant infections.\n\nID: 42388939\nTitle: Clinical Impact of Biofilm-Producing Carbapenem-Resistant Acinetobacter baumannii: Diagnosis and Treatment Challenges.\nAbstract: Carbapenem-resistant Acinetobacter baumannii (CRAB) has emerged as a major nosocomial pathogen associated with significant morbidity and mortality, particularly in intensive care unit (ICU) settings. Its remarkable ability to survive in adverse environments, persist on medical devices, and rapidly acquire multidrug resistance has made it a critical global healthcare concern. This review aims to provide a comprehensive overview of the epidemiology, risk factors, antimicrobial resistance mechanisms, and pathogenicity of CRAB, with a special emphasis on the role of biofilm formation. CRAB infections are strongly associated with prolonged hospitalization, mechanical ventilation, previous antibiotic exposure, and invasive procedures. The organism exhibits multiple resistance mechanisms, including carbapenemase production, efflux pumps, porin modifications, and horizontal gene transfer, which significantly limit therapeutic options. A key virulence factor is its capacity to form biofilms on biotic and abiotic surfaces, enhancing bacterial survival, immune evasion, and resistance to antimicrobial agents. Biofilm-associated infections are often chronic, recurrent, and difficult to eradicate, particularly in device-related infections. The interplay between biofilm formation and antimicrobial resistance further complicates treatment outcomes. Current management strategies rely on last-resort antibiotics, combination therapy, antimicrobial stewardship, and strict infection control practices, while emerging therapies targeting biofilms offer promising alternatives. Understanding these complex mechanisms is essential for developing effective therapeutic and preventive strategies against CRAB infections.\n\nID: 42383980\nTitle: Lineage-specific loss of the type VI secretion system in Acinetobacter baumannii ST19 is associated with reduced accessory genome content.\nAbstract: The type VI secretion system (T6SS) is a widespread bacterial nanomachine involved in interbacterial competition and environmental adaptation. Its distribution and evolutionary significance in Acinetobacter baumannii is not fully understood. Here, we investigated the ST19 lineage, revealing a near-complete absence of the T6SS across 159 genomes from diverse geographic and clinical origins. Comparative genomic analysis showed that the T6SS locus in ST19 is frequently disrupted, with some isolates harboring insertions of mobile genetic elements, while in others, the region is fragmented or unresolved. To assess whether T6SS loss is associated with broader genomic changes, we analyzed 8,218 publicly available A. baumannii genomes. Interestingly, T6SS-negative genomes did not exhibit increased acquisition of accessory genetic material. Instead, they carried fewer antimicrobial resistance genes (8.06 vs 10.56 per genome), fewer virulence genes (101.8 vs 132.5 per genome), and comparable plasmid replicon content relative to T6SS-positive genomes. However, T6SS-negative genomes exhibited a higher number of insertion sequences (IS) per genome compared to T6SS-positive genomes (mean ~12.3 vs ~9.0 IS elements per genome, respectively). Ancestral state reconstruction of the frmRAB and the putative chlorite dismutase genes within ST19 revealed identical distribution patterns and strong phylogenetic conservation, with 7 inferred state transitions indicating limited evidence for independent gain or loss events. Our results suggest that T6SS loss represents a lineage-specific evolutionary trajectory characterized by loss of the T6SS locus and reduced accessory genome, suggesting an alternative ecological strategy.\n\nID: 42381239\nTitle: A novel mouse model of chronic Pseudomonas aeruginosa infection inducing bronchiectasis-like phenotype.\nAbstract: Given the need to translate basic research into human therapies, the development and refinement of clinically relevant animal models for bronchiectasis are critically important. To date, there are no well-established animal models for bronchiectasis. Thus, our aim was to develop a novel animal model that accurately recapitulates bronchiectasis-like pathologies. To address this question, clinical strains of chronic Pseudomonas aeruginosa (CPA) were embedded in agar beads in\u00a0vitro; then CPA-loaded agar beads and papain were repeatedly instilled intratracheally in female C57BL/6\u2009J mice. Experimental assessments included micro-computed tomography (micro-CT) imaging, histological analysis, immune cell infiltration, cytokines, and lung function parameter measurements to evaluate structural damage, immune responses, and lung function impairments in the mouse model. In this mouse model, we observed that lung micro-CT imaging revealed significant bronchiectasis, with visible airways in the periphery, cylindrical airway expansion, and an airway-to-artery ratio >\u20091. Histopathology highlighted immune cell infiltration around the trachea, including lymphocytes, neutrophils, and monocytes, along with Periodic acid-Schiff staining-positive hypermucinous secretion. Compared to controls, the bronchiectasis group exhibited elevated pro-inflammatory cytokines in bronchoalveolar lavage fluid and worse lung function. Our study presented a novel mouse model that better replicated the bronchiectasis-like phenotype than the CPA airway infection model, showing the advantages of the \"CPA-loaded agar beads and papain\"-driven approach in optimizing the disease models. The model mimicked the progression of bronchiectasis closely and could be used for studies on disease pathogenesis as well as the evaluation of novel therapies in the near future.\n\nID: 42380383\nTitle: Molecular and computational analysis of conserved outer membranes (oprI and oprL) in MDR clinical isolates of Pseudomonas aeruginosa as potential vaccine targets from Lahore, Pakistan.\nAbstract: Pseudomonas aeruginosa is a multidrug-resistant pathogen, highly prevalent in ICU patients and is a rising concern globally. Multidrug resistance (MDR) and virulence of P. aeruginosa has been a major reason linked to the high rates of mortality in both developed and non-developed countries. The study focused specifically on main structural outer membrane proteins mainly oprI and oprL due to their significant role on both virulence and MDR by assessing their MDR from the isolates collected from various healthcare settings in Lahore, Pakistan. A total of 65 isolated were collected from different tertiary care hospitals of Lahore, Punjab. All isolates were identified and characterized using conventional methods. MDR patterns were assessed through disk diffusion method in accordance with CLSI 2024 guidelines. Detection of virulence genes (oprI and oprL) was performed using PCR amplification. Statistical and in silico analysis was performed to analyse the prevalence of P. aeruginosa and identification of potential vaccine targets provide alternative treatment strategies against infections caused by it. Out of all 65 isolates, total of 52 isolates was reportedly positive with P. aeruginosa and showed 100% resistance to \u03b2-lactams with high susceptibility to cephalosporins and fluoroquinolones. Multidrug resistance was reported in 70% isolates of P. aeruginosa. All isolates (100%) harbored the oprL gene while the oprI gene was detected in 85.5% of isolates. In silico characterization revealed strong binding B and T cell epitopes with 100% conservancy as potential multi-epitope candidates that warrant further in vivo and in vitro validation to overcome deadly infections caused by P. aeruginosa. In conclusion, MDR and virulence gene characterization by both molecular and computational methods will aid in developing multi-epitope vaccine candidate that can be tested in vitro and in vivo to overcome MDR and rising mortality rates in Pakistan.\n\nID: 42421768\nTitle: Compartment-Specific Variation in Bacterial Microbiome and Polyphyllin Profiles in Paris polyphylla.\nAbstract: Paris polyphylla (P. polyphylla) is a valuable traditional Chinese medicinal plant, yet the spatial distribution of its compartment-specific bacterial microbiomes and their correlative relationships with bioactive polyphyllins remain poorly characterized. Here, we combined 16S rRNA amplicon sequencing, metabolite analysis, and bioinformatics to investigate the distribution patterns of bacterial communities and polyphyllins across bulk soil (BS), rhizosphere soil (RS), root endospheres (REs), stem endospheres (SEs), and leaf endospheres (LEs) of P. polyphylla. A spot inoculation assay was further used to verify the interactions between the dominant genus Pseudomonas (strain Pseudomonas palleroniana P6) and key polyphyllin I and VII. The results showed that polyphyllin I and II were highly accumulated in aerial SEs and leaves, whereas polyphyllin VI, VII, and diosgenin were predominantly concentrated in REs. Bacterial diversity and richness showed a gradual decline from BS to LE, with ecological niche differentiation identified as the primary driver of bacterial community divergence across compartments, which was further modulated by polyphyllin content. Pseudomonas, the dominant genus in all compartments, displayed a decreasing relative abundance with ascending compartmental niches, and its abundance was significantly negatively correlated with polyphyllin I levels but positively correlated with polyphyllin VII levels-a trend experimentally validated by gradient polyphyllin concentration-based microbial growth assays. Redundancy analysis (RDA) indicated that polyphyllin content (especially VI, VII, and diosgenin) significantly influenced bacterial community composition. Additionally, P. polyphylla exhibited selective enrichment of beneficial microbes, with selection pressure intensifying progressively across compartments. This study clarifies the compartment-specific distribution patterns of bacterial microbiomes and polyphyllins in P. polyphylla and their correlative relationships, deepens the understanding of plant-microbiome interactions in medicinal plants, and provides a theoretical basis for optimizing P. polyphylla cultivation strategies and developing microbial inoculants for sustainable agricultural production.\n\nID: 42421616\nTitle: Protective Rhizobacterial Strains Against Black Shoot Blight Caused by Erwinia pyrifoliae on Apple Plants.\nAbstract: Disease suppression against black shoot blight caused by Erwinia pyrifoliae was evaluated using rhizobacterial strains isolated from Jeju Island in apple plants. Total 81 rhizobacterial strains were isolated from plant rhizospheres collected on Jeju Island. Among them, three isolates DR1-6, DR2-3, and DRB1-1 exhibiting antibacterial activity on artificial media were selected for further evaluation. In inoculation bioassays, disease severity on apple leaves was significantly reduced following treatment with mixtures of E. pyrifoliae and the rhizobacterial strains. Notably, DRB1-1 and DR2-3 reduced disease severity to levels comparable to antibiotic treatment, while DR1-6 showed only moderate suppression despite strong in vitro antibacterial activity. Quantitative analysis using qPCR revealed significant reductions in E. pyrifoliae populations on treated leaves, consistent with disease suppression. Based on 16S rRNA gene sequence analysis and scanning electron microscopy, strains DR1-6, DR2-3, and DRB1-1 were identified as Pseudomonas fluorescens, Serratia nematodiphila, and Paenibacillus polymyxa, respectively. These results indicate that the selected rhizobacterial strains have potential as biocontrol agents for managing black shoot blight in crop plants, including apple.\n\nID: 42410687\nTitle: Endophytic Microbiome Diversity in Citrus Leaves and the Biocontrol Potential Bacteria against Xanthomonas citri subsp. citri.\nAbstract: Citrus is a pivotal economic crop in southern China, while citrus canker caused by Xanthomonas citri subsp. citri (Xcc) is a devastating quarantine disease that severely threatens the sustainability of the citrus industry. Endophytic bacteria represent a promising sustainable alternative for disease management, yet systematic exploration of their potential against Xcc in citrus leaves remains limited. To address this, we characterized the leaf endophytic microbiome from major citrus-growing regions in southern China via high-throughput sequencing, revealing significant differences in the endophytic bacterial community structure between symptomatic and asymptomatic citrus leaves, with a significantly elevated relative abundance of Proteobacteria and prominent enrichment of the genera Xanthomonas, Enterobacter, and Pseudomonas in symptomatic tissues. Furthermore, symptomatic leaves harbored significantly higher endophytic bacterial diversity than asymptomatic leaves from the same production region, and the Xanthomonas abundance in the samples was highly consistent with the actual field disease severity. From 519 bacterial isolates, four strains-A1 (Bacillus altitudinis), A3 (Bacillus velezensis), A6 (Pseudomonas parafulva), and A7 (Delftia tsuruhatensis) demonstrated strong in vitro and detached-leaf antagonism against Xcc. Strain-specific fermentation parameters were optimized, and all four strains were successfully formulated into wettable powders. In a field trial, these formulations achieved control efficacies ranging from 25.8% to 53.5%, with strain A1 showing the highest and most sustained activity. Strains A3, A6, and A7 also exhibited broad-spectrum antibacterial activity against several other phytopathogenic bacteria. This study not only elucidates shifts in the endophytic microbiome associated with citrus canker but also provides novel, efficacious biocontrol resources and a practical development pipeline for sustainable disease management.\n\nID: 42402899\nTitle: Mechanistic insights into the inhibition of biofilm formation and antibacterial action of endophytic Streptomyces strain KJ7TB2 isolated from the Indian Sundarbans Mangrove estuary.\nAbstract: To explore the mechanism involved in the inhibition of biofilm formation and antibacterial action of endophytic Streptomyces sp. isolated from the Indian Sundarbans Mangrove Forest. In this study, Streptomyces sp. KJ7TB2 was isolated from the Indian Sundarbans. An ethyl acetate extract was subjected for GC-MS profiling. The mechanisms of antibacterial and antibiofilm action were also explored. In-silico molecular docking and dynamics simulation analyses were performed. The GC-MS analysis of the extract revealed 14 distinct bioactive secondary metabolites. The extract exhibited potent MIC values of 250\u2009\u03bcg/mL and 125\u2009\u03bcg/mL against Escherichia coli MTCC 1195 and Pseudomonas aeruginosa ATCC 27853. Antibiofilm investigation further revealed inhibition of biofilm formation in both pathogens especially in E. coli MTCC 1195, likely by disrupting initial surface adhesion and exopolysaccharide synthesis. Also, the extract inhibited swarming motility, suggesting interference with flagella-driven motility and quorum sensing. The brine shrimp lethality assay confirmed a favorable safety profile, recording limited mortality (36.84% at 2\u00d7MIC over 24\u2009h). In-silico molecular docking and dynamics simulation analyses exhibited robust affinity for two key biofilm-associated proteins, exhibiting significant binding energy (\u0394G). The study highlights Streptomyces sp. KJ7TB2 as a potential source for the discovery of safe, potent therapeutics. Exploring a Mangrove-derived microbe to fight against drug-resistant germs. Antibiotic resistance is a serious global health risk. Many antibiotics do not work as well as before. Because of this, bacterial infections are becoming harder to treat. Scientists are looking for new medicines from natural sources. In this study, we found a rare, helpful microbe from the mangrove forests of the Indian Sundarbans. These forests contain many useful microorganisms. A rare bacteria called Streptomyces sp. KJ7TB2 was collected and grown in the laboratory. After cultivation of the bacteria and collecting its extract, chemical studies found 14 useful compounds. The extract showed strong activity against harmful bacteria. It also stopped the bacteria from building protective walls around themselves. It blocks the signals of the bacteria use to talk with each other. Computational studies also supported these results. Safety tests showed very low toxicity of the extract. This means it may be safe for future studies. Overall, this study suggests that Streptomyces sp. KJ7TB2 could be a useful natural source for new treatments against drug-resistant bacterial infections.\n\nID: 42402748\nTitle: SEM evaluation of dental cement surface morphology and microbial adhesion - a comparative study.\nAbstract: This study aimed to compare the surface morphology and antimicrobial/antibiofilm behavior of three semi-permanent cements used in implantology: FOZ (zinc oxide-based), DT (resin-based), and CIS (glass ionomer), after aging in air and artificial saliva, and after exposure to clinically relevant oral microbial strains. Surface morphology and elemental composition were analyzed by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), and antimicrobial and antibiofilm activity was quantified by determining the number of colony-forming units (CFU\u2215mL) for Gram-positive bacteria (Staphylococcus aureus, Enterococcus faecalis), Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), and fungi (Candida albicans, C. parapsilosis). FOZ exhibited a very rough surface rich in zinc, associated with the most pronounced reduction in microbial adhesion; CIS showed a relatively compact ionomer matrix with barium-rich domains and good antibiofilm activity, particularly against P. aeruginosa, while DT exhibited a predominantly organic, smooth surface with isolated inorganic aggregates and a more pronounced inhibition profile against E. coli. The results indicate that the microstructure and surface chemical composition of the cements directly influence the pattern of microbial colonization and antibiofilm efficacy, providing a rationale for selecting the cementing material based on microbiological risk and specific clinical conditions.\n\nID: 42402019\nTitle: Photosynthesis-driven interactions in the phycosphere enhance bacterial extracellular superoxide production.\nAbstract: Extracellular superoxide generated by heterotrophic bacteria influences aquatic redox transformations, yet its regulation within the phycosphere remains poorly understood. Here, we show that the cyanobacterium Microcystis aeruginosa enhances extracellular superoxide production by Pseudomonas sp. QJX-1 under illumination. Cocultivation increased extracellular superoxide production approximately threefold over bacterial monoculture, with maximum enhancement during carbon starvation. Membrane separation localized detectable superoxide production to the bacterial chamber, indicating that diffusible algal products stimulated bacterial superoxide production. Mechanistically, illuminated cocultures showed 20.4% higher photocurrent than algal monocultures and accumulated the highest extracellular NADP(H) levels, indicating intensified photosynthesis-associated extracellular redox activity. Reduced nicotinamide cofactors stimulated diphenyleneiodonium-sensitive QJX-1-associated superoxide production, consistent with an oxidoreductase-associated route for one-electron reduction of molecular oxygen. In parallel, coculture accumulated catecholate siderophores, consistent with intensified microscale Fe competition; this siderophore-enhanced response required metabolically active bacterial cells and was attenuated by respiratory-chain inhibition. Representative extracellular redox-active and algal photoactive components further enhanced the bacterial response, with cytochrome c and chlorophyll a stimulating QJX-1-associated superoxide production under defined conditions. Functionally, during the carbon-starvation interval coinciding with peak superoxide production, the apparent sulfamethoxazole removal rate constant in coculture was 2.6 times that observed for QJX-1 alone. Moreover, quenching extracellular reactive oxygen species impaired metabolic activity under diverse chemical stressors and reduced carbon, nitrogen, and phosphorus substrate utilization. Collectively, these findings identify photosynthesis-dependent phycosphere interactions as regulators of bacterial superoxide production, linking biogenic reactive oxygen species to contaminant transformation, chemical-stress resilience, and elemental nutrient turnover.\n\nID: 42400354\nTitle: Single-Center Experience in Pediatric Lung Transplantation: Clinical Characteristics, Survival, and Post-Transplant Morbidity.\nAbstract: Pediatric lung transplantation remains a life-saving option for selected children and adolescents with end-stage lung disease. We aimed to describe clinical characteristics, survival, post-transplant morbidity, and exploratory factors associated with mortality in a single-center Saudi cohort. We retrospectively reviewed all pediatric patients who underwent lung transplantation between January 2010 and December 2023. Demographic, anthropometric, perioperative, and post-transplant data were extracted. Survival was assessed with Kaplan-Meier analysis, and Cox regression was used to explore associations with mortality. Twenty-eight recipients underwent transplantation, predominantly bilateral sequential procedures, at a median age of 16\u2009years. All recipients were adolescents, and cystic fibrosis (CF) was the most common indication. Severe undernutrition was common, with 64.3% meeting failure-to-thrive criteria (<\u20091st centile for weight) and 71.4% below the 3rd centile. Intraoperative extracorporeal membrane oxygenation replaced cardiopulmonary bypass after 2016. One-year survival was 96.4%, and median post-transplant survival was 6.8\u2009years. Survival did not differ significantly by intraoperative extracorporeal support, but median survival was shorter in CF than in non-CF recipients (2.9 vs. 8.9\u2009years). Hypertension developed in 53.5% of patients, diabetes in 28.5%, and acute kidney injury in 46.4%. In age- and sex-adjusted Cox models, CF, longer waiting time, Pseudomonas aeruginosa colonization, and diabetes at 1\u2009year were associated with mortality. Pediatric lung transplantation in this cohort achieved excellent short-term survival but substantial long-term morbidity. Mortality associations should be interpreted cautiously, given the small sample size and event count. The shorter survival observed in CF recipients warrants further study, particularly in the context of severe undernutrition and chronic airway colonization.\n\nID: 42394828\nTitle: Gut barrier dysfunction and multidrug-resistant bacterial translocation in adult critical illness: Mechanistic insights from a systematic review.\nAbstract: The gastrointestinal tract plays an important role in host defence during critical illness. Disruption of epithelial integrity, microbiome imbalance, and immune dysregulation have all been linked to the translocation of multidrug-resistant (MDR) organisms from intestinal colonization to invasive infection. However, whether these associations reflect true causal mechanisms remains uncertain, and available human evidence has not been comprehensively synthesized using current methodological standards. To systematically evaluate human evidence examining the relationship between intestinal barrier dysfunction, microbial colonization, and subsequent MDR infection in adult critical illness, with particular attention to study quality, heterogeneity, and potential confounding factors. This systematic review was conducted in accordance with PRISMA guidelines. A structured literature search was performed in PubMed, EMBASE, and the Cochrane Library (2000-2025) using predefined Boolean combinations and Medical Subject Headings. Prospective and retrospective cohort studies involving intensive care units (ICU) adults were included if they evaluated intestinal colonization, biomarkers of barrier dysfunction (citrulline and intestinal fatty acid-binding protein), microbiome alterations, or endotoxemia. Study selection and data extraction were undertaken independently by two reviewers, with disagreements resolved through discussion. Risk of bias was assessed using the Newcastle-Ottawa Scale and ROBINS-I tool. Owing to methodological and clinical heterogeneity, findings were synthesized using a structured narrative approach rather than meta-analysis. Across the included studies, intestinal colonization with carbapenem-resistant Enterobacteriaceae, carbapenem-resistant Klebsiella pneumoniae, Acinetobacter baumannii, and vancomycin-resistant Enterococcus was consistently associated with an increased risk of subsequent bloodstream infection. However, progression rates varied considerably across cohorts, likely reflecting differences in patient characteristics, antimicrobial exposure, and ICU practices rather than a consistent effect size. Biomarker studies showed reduced citrulline levels and elevated intestinal fatty acid-binding protein concentrations in patients with gastrointestinal dysfunction; however, these markers indicate enterocyte injury rather than directly measuring intestinal permeability or bacterial translocation. Microbiome analyses demonstrated reduced diversity and impaired colonization resistance, although the extent and timing of these changes were not uniform across studies. Taken together, the evidence supports a biologically plausible link between epithelial injury, dysbiosis, and infection risk, but does not establish a direct causal relationship, largely due to the observational design of available studies and the influence of confounding factors such as illness severity, antimicrobial exposure, and ICU environment. Gut barrier dysfunction appears to contribute to the pathogenesis of MDR infection in critically ill adults; however, current evidence supports association rather than causation. Early recognition of intestinal colonization and strategies aimed at preserving mucosal integrity may offer potential clinical benefit, although their effectiveness requires confirmation in well-designed prospective and interventional studies.\n\nID: 42391963\nTitle: Transport specificity of FpvA and FpvB for pyoverdine-antibiotic conjugates in Pseudomonas aeruginosa.\nAbstract: Pyoverdines (PVDs) are fluorescent siderophores produced by many Pseudomonas species. In P. aeruginosa, the TonB-dependent transporters (TBDT) FpvA and FpvB mediate PVD-dependent iron acquisition. PVDs have emerged as promising vectors for antibiotics in antibacterial Trojan horse strategies. However, the uptake of PVD-antibiotic conjugates by FpvA and FpvB remains poorly characterized. Here, we report the semisynthesis of a PVD-oxazolidine conjugate used as a molecular tool to investigate how P. aeruginosa accesses iron via these TBDTs in the presence of two native PVDs and their corresponding antibiotic conjugates. Growth assays demonstrate that P. aeruginosa can access iron chelated by PVDs through both FpvA and FpvB. In contrast, although both antibiotic conjugates provide iron to the strain via FpvA, only one does so via FpvB, indicating differential receptor recognition. Docking analyses reveal that native PVDs adopt similar binding modes within both FpvA and FpvB. However, FpvB-previously described as a broadly selective transporter-exhibits selective restriction toward PVD-antibiotic conjugates. Our results provide insights for the design of PVD-antibiotic conjugates and emphasize the critical role of the conjugation site on PVD in ensuring efficient transporter-mediated uptake.\n\nID: 42391898\nTitle: Biocontrol effects of bacteria isolated from compost tea against postharvest disease of tomato fruit (Solanum lycopersicum L.).\nAbstract: Prominent postharvest pathogens of tomato fruit include Alternaria spp. and Botrytis cinerea. While the control of such pathogens typically relies on synthetic chemical fungicides preharvest, microbial biocontrol agents are a sustainable and promising alternative postharvest. Bacillus velezensis SH1 and SH2 and Pseudomonas azotoformans SH3 were previously isolated from disease-suppressive compost tea. To evaluate their effectiveness against tomato pathogens, the bacteria, their cell-free culture filtrates and precipitated subfractions were tested against mycelial growth in vitro. Suppressive effects were also examined against disease development on tomato fruit. From bacterial precipitates, lipopeptides were further identified and quantified. Results showed that all bacteria controlled growth of the three fungi, with P. azotoformans SH3 generally being the most effective. However, in vivo disease lesion suppression varied according to pathogen and tomato cultivar. In cell-free culture filtrate assays, mycelial inhibition was observed from all bacteria against B. cinerea, whereas mainly B. velezensis SH1 inhibited A. solani and A. alternata growth. For bacterial precipitates, B. velezensis SH1 was the best treatment overall, while P. azotoformans SH3 precipitates showed no inhibition. Both B. velezensis strains were confirmed to produce fengycins, iturins and surfactins. Fengycins seemed to play the most important role in the observed activity of the Bacillus lipopeptides. Results suggest that antifungal activity by the bacterial strains is imparted through the release of antifungal compounds, although the role of the produced compounds was variable.\n\nID: 42391643\nTitle: K38 Succinylation of CsrA Regulates Biofilm Formation in Pseudomonas fluorescens PF08 by Modulating c-di-GMP Levels.\nAbstract: Pseudomonas fluorescens PF08 is a significant food spoilage organism belonging to a species widely utilized for agricultural biocontrol, yet the post-translational regulation of its biofilm formation remains poorly understood. This work explored the role of lysine succinylation (Ksucc) in regulating CsrA activity, a global post-transcriptional regulator. NanoHPLC-MS/MS identified Lys38 (K38), a highly conserved residue within the CsrA RNA-binding interface, as a functional succinylation site. Site-directed mutagenesis revealed that K38 succinylation significantly inhibits biofilm formation by reducing c-di-GMP levels, exopolysaccharide production, and surface hydrophobicity, while enhancing flagellar-mediated motility. Colonization assays on foods, contact surfaces, and the rhizosphere confirmed that CsrA succinylation restricts biofilm formation across diverse ecological niches. These results identify K38 succinylation of CsrA as a regulatory modification that modulates the transition between motile and sessile lifestyles in P. fluorescens PF08. These findings expand the understanding of post-translational control of biofilm formation in this ecologically versatile bacterium relevant to food spoilage and agricultural environments.\n\nID: 42390031\nTitle: Biocontrol Efficacy of Endophytic Bacteria from Lawsonia inermis L. Against Phytopathogens Fusarium oxysporum and Rhizoctonia solani.\nAbstract: Bioactive compounds from endophytic bacteria contribute significantly to drug discovery and plant defense. Medicinal plants, such as Lawsonia inermis L., serve as a rich source of microbial endophytes. To isolate and characterise endophytic bacteria from L. inermis leaves and evaluate their bioactive metabolites for antimicrobial and biocontrol potential. Endophytic bacteria were isolated from surface-sterilised leaves of L. inermis. Morphological and molecular identification, including 16S rRNA gene sequencing and phylogenetic analysis, identified the isolates as Bacillus subtilis, Pseudomonas mosselii, and Sphingomonas aquatilis. Metabolite profiling was performed using Fourier transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry (GC-MS). Antifungal activity was tested against Fusarium oxysporum f. sp. lycopersici and Rhizoctonia solani using dual-culture assays. The endophytes demonstrated significant antagonistic activity, inhibiting the growth of fungal mycelia. FTIR spectra indicated the presence of carboxylic, ester, ketone, and alkane functional groups. GC-MS analysis of active fractions revealed several known antimicrobial and pharmaceutical compounds, supporting the observed bioactivity. Endophytic bacteria from L. inermis produce bioactive secondary metabolites with potent antifungal activity. These findings suggest their potential as sources of novel biocontrol agents and therapeutic compounds, contributing to the medicinal properties of the host plant.

Understanding the bacteriological profile and antibiotic sensitivity is essential for guiding therapy and curbing inappropriate antibiotic use. Therefore, this study aimed to determine the bacteriological profile of burn wounds and assess antimicrobial sensitivity on the 1st, 5th, and 10th post-burn days in a tertiary burn care center. A prospective observational study was conducted at National Institute of Burn and Plastic Surgery (NIBPS), Dhaka, Bangladesh, from July 2022 to December 2023. A total of 110 patients with burns involving 10-50% of total body surface area were enrolled and followed longitudinally. Wound swabs were collected from the same patients on the first, fifth, and 10th post-burn days to assess the early, intermediate, and later phases of bacterial colonization and antimicrobial susceptibility changes over time. Isolates were identified by standard microbiological techniques, and antibiotic susceptibility testing was performed using the CLSI disc diffusion method. Children under 10 years constituted the largest proportion of cases (43.6%). Flame burns predominated (50%), with the trunk most commonly affected (73.6%). Bacterial growth increased from 36.4% on day 1 to 86.4% by day 5 and remained high on day 10. Gram-negative organisms predominated throughout the study period, with Pseudomonas aeruginosa being the most frequent isolate. None of the tested antibiotics demonstrated consistently high susceptibility. Colistin demonstrated comparatively higher susceptibility than other tested antibiotics, although susceptibility rates remained suboptimal. Burn wounds showed rapid colonization predominantly by gram-negative organisms, particularly Pseudomonas aeruginosa, with low antibiotic susceptibility across several commonly used agents. The findings highlight the potential importance of continuous microbiological surveillance, burn unit-specific antibiograms, antimicrobial stewardship, and rational antibiotic use in burn care settings.\n\nID: 42383755\nTitle: The gac system integrates physical and chemical cues to promote plant root attachment.\nAbstract: Plants host complex communities of microbes that are attached to root surfaces. While many studies have sampled mutant populations after prolonged incubation on roots to identify bacterial genes that enable long-term colonization, the molecular mechanisms governing the early stages of root attachment remain less understood. Here, we developed an in vitro root culture system that enables controlled and scalable investigation of bacterial attachment to root tissue. We used this platform to perform a genome-wide screen for root attachment determinants in the plant-associated bacterium Pseudomonas protegens Pf-5. Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment. Mutations that disrupt gacS or gacA cause severe root attachment defects despite having no effect on abiotic surface attachment in standard biofilm assays. Mutation of flagellar assembly genes enhances root attachment by mimicking surface contact and activating the gac system. In parallel, chemical cues released by roots stimulate surface attachment in a gac-dependent manner. By integrating these signals, the gac system activates cyclic-di-GMP-mediated attachment programs that drive the transition from planktonic to sessile behavior required for root association. We build on this model to show that manipulating flagellar surface-sensing sustains the attachment of Pf-5 in the presence of a synthetic bacterial community, suggesting a strategy to improve the attachment of beneficial microbes on crops. These findings establish a mechanistic framework linking surface sensing, global regulation, and root attachment in a beneficial rhizobacterium.IMPORTANCEPlant roots are covered with diverse microbes that strongly influence plant health. Growing in association with roots has many benefits, but how bacteria attach to root tissue remains poorly understood. We developed a system to study how the plant-associated bacterium Pseudomonas protegens Pf-5 attaches to roots. We found that physical contact with the root surface and chemical cues released by roots both enhance attachment to roots. A sensory system called gacSA is responsible for integrating physical and chemical cues to activate a root attachment program. Variant bacteria that prematurely activate the gac system attach more effectively even in the presence of other bacteria on roots, suggesting that the root attachment pathway we characterized could serve as a strategy to use beneficial bacteria in agriculture.\n\nID: 42382725\nTitle: Single-dose dual-indication nanoparticle vaccine co-displaying Pseudomonas aeruginosa antigen and tetanus toxin fragment confers durable protection against mixed exposure.\nAbstract: Trauma, disaster, and conflict-related injuries can create clinically important co-exposure to Pseudomonas aeruginosa (PA) and tetanus toxin, where disrupted barriers and contaminated wounds enable simultaneous bacterial infection and toxin entry. Until now no licensed PA vaccine exists and multi-dose schedules are difficult to complete in emergency settings, thus a single-dose, dual-indication vaccine that provides rapid and durable protection is urgently needed. Here, we engineered and characterized a lumazine synthase (LS) nanoparticle vaccine (rePO-TTFC@LS) that co-displays a PA antigen (rePO; PcrV-OprI fusion) and tetanus toxin fragment C (TTFC). In BALB/c mice, rePO-TTFC@LS enhanced antigen uptake and dendritic-cell activation relative to soluble antigens. After a single intramuscular immunization, rePO-TTFC@LS elicited rapid, high anti-rePO and anti-TTFC IgG responses together with increased IFN-\u03b3/IL-4/IL-17A-secreting splenocytes. Vaccination reduced lung bacterial burden and pulmonary IL-1\u03b2/IL-6 and improved survival and clinical outcomes in an acute PA pneumonia model, which provided complete protection against lethal tetanus toxin challenge, and decreased PA colonization with improved survival in a femoral fracture-implant co-infection model. Elevated antibody titers and dual protection persisted to 28 weeks after one dose, and biosafety assessments showed no meaningful hemolysis or cytotoxicity and no abnormalities in hematology/serum biochemistry or multiorgan histopathology. Collectively, these results support rePO-TTFC@LS as a single-dose, durable dual-indication nanoparticle vaccine and highlight a modular strategy for combination vaccines suited to mixed-exposure emergency scenarios.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

The mammal gut demonstrates an interesting source of virulence bacteriophages. The gut with inflammation is phage-rich; therefore, we primarily aimed to prove the concept that an inflammatory gut is a possible source of effective phages and to evaluate the efficacy of the candidate phage against Pseudomonas aeruginosa in vitro and in a mouse model of infected wounds. The gut microbiome of cecal ligation and puncture (CLP) sepsis mice, an animal model of inflammation, showed a dominant presence of Podoviruses. CLP bacteriophages (CLP \u03a61-\u03a64), of which the CLP \u03a64 possessed the broadest bactericidal activity (viable bacterial cell reduction in time-kill study) against P. aeruginosa isolates. The CLP \u03a64 specifically killed the Pseudomonas aeruginosa clinical (PACL) strain with two huge burst events. Although the CLP \u03a64 had no effect on ex vivo mouse bone marrow-derived macrophage (BMDM) cytokine gene expression and cytokine production, the CLP \u03a64 attenuated the severity of the P. aeruginosa-infected wound mouse model after treatment. P. aeruginosa PACL exhibited significantly pathogenic characteristics in a mouse model, including excessive bacterial loads (in wounds and internal organs, indicating the systemic infection due to localized infected wound with P. aeruginosa), increased IL-6 cytokine (in serum), upregulated IL-6 expression (in wounds), and immune cell infiltration (in wounds), indicating severe inflammation. In the CLP \u03a64 treatment alone, the wound tissues upregulated IL-10 expression and recruited inflammatory cells. Interestingly, the three-day CLP \u03a64 treatment was adequate to eradicate P. aeruginosa PACL in the wounds and other internal organs. After treatment, the mouse serum cytokine showed a remarkably decreased IL-6. Likewise, IL-6 downregulation and IL-10 upregulation were demonstrated in the treated wounds, suggesting an anti-inflammatory shift. These results demonstrated the effectiveness (bacterial wound and internal organ clearance and cytokine modulation) of the CLP \u03a64 in the P. aeruginosa-infected wound and systemic infection. Finally, the CLP \u03a64 isolation verified a proof of concept that the irritated gut acts as a source of bacteriophages. The gut virome was a promising and interesting source of antimicrobial and immunomodulating bacteriophage.\n  --- END ACTUAL ABSTRACT FOR 42404584 ---\n\n- ERROR: You cited ID: 42414399 for the quote: \"This computational framework integrating pangenome analysis of 712 complete genomes, epitope prediction, and structural vaccinology was employed to design a multi-epitope nanoparticle vaccine candidate for experimental evaluation.\"\n  FACT: Strict Misquote Detected!

This study aims to identify universally conserved surface antigens through pangenome analysis, predict immunogenic epitopes using integrated machine learning, and computationally design and in silico characterize a self-assembling nanoparticle vaccine with dual adjuvants. A computational framework integrating pangenome analysis of 712 complete genomes, epitope prediction, and structural vaccinology was employed to design a multi-epitope nanoparticle vaccine candidate for experimental evaluation. Pangenome analysis identified 3894 core genes with 42 outer membrane proteins, prioritizing OmpA, BamA, and OmpW as antigen targets. Protein language models predicted conformational B-cell epitopes, while NetMHCpan-4.2 predicted T-cell epitopes across 125 HLA alleles. The final construct (AB-VAX-01, 289 amino acids) incorporates 15 epitopes fused with dual adjuvants (RS09 TLR4 and cGAMP STING agonists) and a foldon domain for nanoparticle assembly. Microsecond molecular dynamics simulations with replicates demonstrated stability with TLR4 and STING. Conservation analysis across all 712 genomes showed 96.2-100% epitope identity. Immune simulations predicted Th1-biased responses with 94.2% global population coverage. In silico cloning confirmed favorable codon adaptation parameters. This in silico characterized vaccine construct represents a promising candidate requiring experimental validation against A. baumannii infections.\n  --- END ACTUAL ABSTRACT FOR 42414399 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Antimicrobial peptides (AMPs) have emerged as promising therapeutic candidates due to their broad-spectrum activity and low propensity for resistance development.\" (Source: 42422065)\n- \"Across these systems, host control operates through three recurring modes: activation or signal mimicry, enzymatic signal degradation, and extracellular sequestration or receptor-level interference.\" (Source: 42418271)\n- \"This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates.\" (Source: 42406312)\n- \"Antibiofilm investigation further revealed inhibition of biofilm formation in both pathogens especially in E. coli MTCC 1195, likely by disrupting initial surface adhesion and exopolysaccharide synthesis.\" (Source: 42402899)\n- \"Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment\" (Source: 42412003)\n- \"Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation.\" (Source: 42412160)\n- \"Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification.\" (Source: 42410210)\n- \"Intratracheal delivery of mRNA-LNP rapidly primes lung neutrophils and macrophages into a transcriptionally pre-activated state, enhancing their phagocytic activity and enabling rapid, antigen-independent bacterial clearance during the early post-vaccination period\" (Source: 42420327)\n- \"Tetrasodium EDTA (tEDTA) is one of the new antimicrobial compounds that have been shown to have good antibacterial and antibiofilm efficacy against P. aeruginosa.\" (Source: 42396178)\n- \"Ribosome hibernation, mediated by hibernation promoting factor (HPF), is essential for optimal survival and resuscitation of starved biofilm cells.\" (Source: 42414298)\n- \"Here, we engineered and characterized a lumazine synthase (LS) nanoparticle vaccine (rePO-TTFC@LS) that co-displays a PA antigen (rePO; PcrV-OprI fusion) and tetanus toxin fragment C (TTFC).\" (Source: 42382725)\n- \"In this study, we revealed that exposure to five types of OPEs (0.1-1000 \u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater.\" (Source: 42401059)\n- \"The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM.\" (Source: 42390567)\n- \"This study synthesized and characterized artemisinin-loaded micelle/liposome nanoparticles (Art/PEG400-OA NPs) and evaluated their antibacterial, antibiofilm, and anticancer efficacy.\" (Source: 42414953)\n- \"Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment.\" (Source: 42383755)\n- \"Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization.\" (Source: 42420271)\n- \"The endophytes demonstrated significant antagonistic activity, inhibiting the growth of fungal mycelia.\" (Source: 42390031)\n- \"The combination of snail mucus in STF is a highly effective remedy for infected wounds, providing complementary benefits in vivo by coupling antimicrobial activity with pro-regenerative functions\" (Source: 42402928)\n\n\nINSTRUCTION: Study the actual abstracts provided.

The literature confirms that these pathogens utilize shared resistance and virulence mechanisms\u2014such as biofilm formation, efflux pumps, and specific regulatory pathways\u2014which are being targeted by non-traditional therapies, including bacteriophages and bioactive compounds, to mitigate the global antimicrobial resistance (AMR) crisis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe rising threat of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* stems from their capacity to form recalcitrant biofilms and utilize sophisticated regulatory networks to escape antibiotic action. Research indicates that both pathogens, often classified as high-priority, share vulnerabilities that allow for the potential application of cross-species therapeutic strategies. Non-antibiotic solutions are critical as traditional antibiotics face decreased efficacy due to envelope layers and efflux systems. Innovations in bacteriophage therapy provide a targeted approach to bypass conventional resistance. Furthermore, the development of nanoparticle platforms and peptides targeting specific proteostasis mechanisms offers a path toward eradicating persistent, multidrug-resistant (MDR) strains. The evidence supports a transition toward multifaceted strategies that integrate host-directed immune modulation with targeted microbial interference.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Transcriptional Regulation:** The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM.\n*   **Proteostasis Vulnerability:** FtsH is the key protective mechanism, as only \u0394ftsH drives a 16-fold sensitization, identifying it as the bottleneck for survival under peptoid stress.\n*   **Immunometabolism:** Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization.\n*   **Host-Directed Defense:** Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment.\n*   **Probiotic Synergy:** Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation.\n*   **Horizontal Gene Transfer:** In this study, we revealed that exposure to five types of OPEs (0.1-1000 \u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater.\n*   **Biocontrol Potential:** The endophytes demonstrated significant antagonistic activity, inhibiting the growth of fungal mycelia.\n*   **Genomic Adaptation:** Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification.\n*   **Signaling Integration:** Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment.\n*   **Evolving Therapeutics:** This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The DRF emphasizes that disease results from cumulative host injury arising from the interplay between microbial virulence and the host immune response, rather than from the pathogen alone. HPI has been described as a \"tug of war\" between a pathogen and a host; the DRF improves this analogy by grounding it in reality, as both excessive immune activation and insufficient pathogen clearance can lead to host damage and disease. Acinetobacter baumannii is a Gram-negative pathogen known for its extensive drug resistance and immunomodulatory capacities. The interaction among isolate-specific virulence traits, antimicrobial resistance mechanisms, and host immune status determines the pattern and extent of damage, illustrating central tenets of the DRF. Different A. baumannii isolates may therefore produce varied clinical outcomes across different host conditions, depending on the extent of damage they cause. This narrative review discusses A. baumannii infections from the perspective of the DRF, highlighting how applying the DRF can inform our current understanding of A. baumannii pathogenesis by assessing A. baumannii HPI. We also provide brief insights into how the DRF can inform future research and treatment strategies that integrate host and microbial factors to minimize overall damage and improve host outcomes. A. baumannii infections are difficult to treat and can result in outcomes ranging from asymptomatic colonization to fatal disease. This narrative review examines these differences through the Damage Response Framework (DRF) to improve understanding of A. baumannii infections. The DRF emphasizes that disease results not only from the microbe but also from the interaction between microbial factors and the body\u2019s immune response. When the total damage from the microbe and the immune response exceeds the body's ability to repair, hosts become sick. Hosts with weak immune responses can become very ill because their immune systems cannot control the infection effectively. Conversely, patients with strong immune responses can also become severely ill when their immune systems damage vital tissues and organs in an effort to eliminate the bacteria. This narrative review draws on existing literature to show that different A. baumannii isolates can cause varying levels of illness, depending on the host\u2019s response to the infection. The review also briefly describes the importance of considering antimicrobial therapy as a potential source of host damage and the utility of the DRF in optimizing therapeutic strategies."

Here, we identify a persistence mechanism mediated by pyruvate secretion resulting from mutations in the pyruvate dehydrogenase complex in clinical isolates of P. aeruginosa, with putative analogous mutations also identified in Staphylococcus aureus, Haemophilus influenzae and Stenotrophomonas maltophilia. These mutations lead to elevated extracellular pyruvate, which dampens host inflammatory responses and favors bacterial persistence. Pyruvate exerts multiple roles: scavenges reactive oxygen species such as H2O2, suppresses host immune activation both in airway epithelial cells and macrophages, and increases bacterial survival during phagocytosis. This metabolic crosstalk promotes bacterial persistence while reducing epithelial and macrophage inflammatory responses. Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization. This work highlights the broader role of secreted metabolites in host-pathogen interactions and suggests new strategies targeting metabolic pathways to manage chronic infections."

The mammal gut demonstrates an interesting source of virulence bacteriophages. The gut with inflammation is phage-rich; therefore, we primarily aimed to prove the concept that an inflammatory gut is a possible source of effective phages and to evaluate the efficacy of the candidate phage against Pseudomonas aeruginosa in vitro and in a mouse model of infected wounds. The gut microbiome of cecal ligation and puncture (CLP) sepsis mice, an animal model of inflammation, showed a dominant presence of Podoviruses. CLP bacteriophages (CLP \u03a61-\u03a64), of which the CLP \u03a64 possessed the broadest bactericidal activity (viable bacterial cell reduction in time-kill study) against P. aeruginosa isolates. The CLP \u03a64 specifically killed the Pseudomonas aeruginosa clinical (PACL) strain with two huge burst events. Although the CLP \u03a64 had no effect on ex vivo mouse bone marrow-derived macrophage (BMDM) cytokine gene expression and cytokine production, the CLP \u03a64 attenuated the severity of the P. aeruginosa-infected wound mouse model after treatment. P. aeruginosa PACL exhibited significantly pathogenic characteristics in a mouse model, including excessive bacterial loads (in wounds and internal organs, indicating the systemic infection due to localized infected wound with P. aeruginosa), increased IL-6 cytokine (in serum), upregulated IL-6 expression (in wounds), and immune cell infiltration (in wounds), indicating severe inflammation. In the CLP \u03a64 treatment alone, the wound tissues upregulated IL-10 expression and recruited inflammatory cells. Interestingly, the three-day CLP \u03a64 treatment was adequate to eradicate P. aeruginosa PACL in the wounds and other internal organs. After treatment, the mouse serum cytokine showed a remarkably decreased IL-6. Likewise, IL-6 downregulation and IL-10 upregulation were demonstrated in the treated wounds, suggesting an anti-inflammatory shift. These results demonstrated the effectiveness (bacterial wound and internal organ clearance and cytokine modulation) of the CLP \u03a64 in the P. aeruginosa-infected wound and systemic infection. Finally, the CLP \u03a64 isolation verified a proof of concept that the irritated gut acts as a source of bacteriophages. The gut virome was a promising and interesting source of antimicrobial and immunomodulating bacteriophage."

The escalating misuse of antibiotics has led to the emergence of multidrug-resistant strains, necessitating novel therapeutic approaches. Bacteriophages and their encoded lytic enzymes offer unique advantages for antimicrobial therapy and show promising potential for future applications. This study focuses on the characterization of uropathogenic P. aeruginosa phages and their lytic enzymes, investigating their biological properties and potential therapeutic applications. We isolated a novel lytic bacteriophage, vB_PaeS_PA16c (PPA16c), which demonstrated favorable biological characteristics, including a 34% biofilm eradication capacity within 6\u2009h. The phage-encoded endolysin PA16cLys exhibited superior antibacterial efficacy compared to the phage itself. Notably, it achieved significant biofilm reduction (~63%) after 1\u2009h treatment without requiring outer membrane permeabilizers. This endolysin exhibited enhanced antibacterial efficacy in eradicating mature P. aeruginosa biofilms. Regarding host range, PA16cLys displayed broader lytic activity. Both the phage and endolysin demonstrated cross-order lytic activity against other pathogenic bacteria. Crucially, PA16cLys maintained potent inhibitory activity against phage-resistant mutants.

In this study, Aloin, an anthraquinone present in the plant Aloe vera, was tested for antibiofilm activity against P. aeruginosa PAO1. Aloin demonstrated efficient biofilm-inhibiting capacity at a sub-MIC dose of 4.8 mM, along with/without GEN at 0.002\u00a0\u00b5g/\u00b5L (sub-MIC), in an additive manner, determined by the FICI test. Furthermore, it reduced biofilm-associated carbohydrates by 66.9%, proteins by 66.22%, and extracellular DNA by 69.57%. In silico analysis revealed that Aloin interacts with key P. aeruginosa proteins, such as RhlI (Glide Score: -6.035\u00a0kcal/mol; Glide e-model score: -60.414\u00a0kcal/mol), LasI (Glide Score: -4.407\u00a0kcal/mol; Glide e-model score: -35.286\u00a0kcal/mol), LasR (chain A) (Glide Score: -3.764\u00a0kcal/mol; Glide e-model score: -36.012\u00a0kcal/mol), LasR (chain B) (Glide Score: -5.015\u00a0kcal/mol; Glide e-model score: -46.672\u00a0kcal/mol), PqsR (Glide Score: -4.701\u00a0kcal/mol; Glide e-model score: -25.491\u00a0kcal/mol), PelA (Glide Score: -6.097\u00a0kcal/mol; Glide e-model score: -53.723\u00a0kcal/mol), and PelB (Glide Score: -5.043\u00a0kcal/mol; Glide e-model score: -53.128\u00a0kcal/mol) by forming strong hydrogen bonds. In silico simulation studies also substantiated the Aloin-protein binding results. The production of virulence factors, such as exoprotease and pyocyanin, was reduced by 71% and 74%, respectively. Furthermore, CLSM and SEM analysis showed a decrease in biofilm thickness from 498\u00a0\u03bcm to 72\u00a0\u03bcm and a reduced denser structure in the presence of Aloin.

A significant synergistic antibacterial effect was achieved with the fractional inhibitory concentration index being 0.5 when the two agents were combined at their respective 1/4 of minimum inhibitory concentration.

Non-targeted metabolomics disclosed that SAEW primarily disturbed histidine and lysine metabolisms, while \u03b5-PLH interfered with arginine and glutathione metabolisms, and their combination triggered broader metabolic reprogramming in the strain, demonstrating a multi-target antibacterial mechanism.

Despite growing interest in its pharmacological properties, studies integrating nanoparticle biosynthesis, comprehensive biological evaluation, and computational analysis remain scarce for its austriacum subspecies. In this study, magnesium nanoparticles (VA-MgNPs) were green-synthesized using the ethanol extract of Viscum album subsp. austriacum as a bioreducing and capping agent, and their biological activities were comparatively assessed alongside the crude extract and Mg(NO3)2\u00b76H2O precursor control. LC-HR/MS analysis identified quinic acid (10,027.49\u202f\u03bcg/g) and chlorogenic acid (5294.12\u202f\u03bcg/g) as the dominant phenolic constituents. The synthesized VA-MgNPs were characterized by FT-IR, UV-Vis, FE-SEM, TEM, and XRD analyses, confirming nanocrystalline formation with a mean crystallite size of approximately 66.47\u202fnm. Antioxidant evaluation using DPPH, ABTS, and FRAP assays revealed that the crude extract retained superior radical scavenging capacity, which is attributed to the consumption of free phenolic hydroxyl groups during nanoparticle formation. In contrast, VA-MgNPs demonstrated markedly enhanced anticancer activity against breast (MCF-7: IC50\u202f=\u202f124\u202f\u03bcg/mL; MDA-MB-231: IC50\u202f=\u202f96\u202f\u03bcg/mL) and colorectal (HCT116: IC50\u202f=\u202f105\u202f\u03bcg/mL; HT-29: IC50\u202f=\u202f135\u202f\u03bcg/mL) cancer cell lines, with lower cytotoxicity toward non-tumorigenic cells, indicating selective antiproliferative action. Although antibacterial activity was limited across tested strains, VA-MgNPs exhibited significant antibiofilm activity, achieving up to 75% inhibition against Pseudomonas aeruginosa. Molecular docking simulations revealed that chlorogenic acid and its magnesium complex displayed strong binding affinities toward antioxidant- and antimicrobial-related protein targets, with binding energies reaching -8.5\u202fkcal/mol, mechanistically supporting the observed biological activities. These findings demonstrate that VA-MgNPs are a promising nanotherapy platform, particularly for antibiofilm and anticancer applications."

These pathogens are progressively acquiring pan-resistance and spreading beyond traditional healthcare settings, yet conventional diagnostic methods remain ill-equipped for point-of-care (POC) deployment due to slow processing times and limited adaptability. CRISPR/Cas systems feature programmable target specificity and intrinsic signal amplification, enabling rapid and accurate nucleic acid detection. Despite these advantages, the translation of CRISPR-based assays for ESKAPE pathogens from proof-of-concept to practical POC tools faces major challenges. Current research is fragmented, and key trade-offs between sensitivity, multiplexing performance and operational simplicity have not been fully addressed. This review offers a critical assessment of the field, moving beyond a simple summary of existing studies to analyze how various CRISPR systems (Cas9, Cas12, Cas13, and Cas14) and amplification strategies address the demands of POC testing. We identify key barriers to clinical application, particularly sample preparation, multiplex detection, reagent stability, and discuss emerging solutions such as microfluidic integration, lyophilized reagents development, and artificial intelligence-driven data interpretation. By focusing on the central question of how to transition from benchtop research to bedside application, this review provides a strategic framework for advancing next-generation CRISPR diagnostics capable of rapid, precise, and real-time detection of drug-resistant ESKAPE pathogens in the fight against AMR."

This study involved 30 patients with thoracic empyema from hospitals in Riau Province, Indonesia. Pleural fluid samples were collected for culture analysis and identification using the Vitek 2 compact system and metagenomic analysis. Patient clinical data were also collected.

Here, we investigated how four genetically and phenotypically distinct Pseudomonas aeruginosa strains respond to sub\u2011MIC copper (Cu) and gentamicin (GE) stress, individually and in combination (Cu\u2009+\u2009GE). Across all strains, Cu acted as the dominant envelope\u2011active stressor, increasing biofilm biomass and extracellular DNA (eDNA) release, suppressing twitching and swarming motility, reducing quorum\u2011sensing\u2011linked protease activity, and enhancing pyomelanin production.

Current culture-based methods require a timeframe of at least 24-48 h for species-level identification alone, which often leads to substantial disease progression and increases the propensity of antimicrobial resistance (AMR). Surface-Enhanced Raman Spectroscopy (SERS) shows promise in mitigating these drawbacks by providing a fast, non-invasive, label-free method to capture the biochemical fingerprints of bacteria achievable under clinical settings. However, the molecular complexity of SERS spectra, which has been an impediment for conventional data analysis, demands robust computational frameworks for reliable species-level identification. Here, we employ a comprehensive SERS analysis scheme with supervised machine learning and explainable artificial intelligence (XAI) to discriminate five clinically relevant pathogens, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), and Enterococcus faecalis, and to probe their degree of pathogenicity from a biomarker perspective. Among the tested models - Support Vector Machine (SVM), k-Nearest Neighbour (kNN), Random Forest (RF), and a 1D Convolutional Neural Network (CNN) - CNN achieved near-perfect classification accuracy, capturing subtle and spectrally relevant variations often inaccessible to traditional algorithms. Notably, the 1D-CNN also achieved 100% discrimination between MRSA and methicillin-sensitive S. aureus - two strains of the same species differing only in resistance phenotype. To ensure transparent decision-making and eliminate the black-box nature of machine learning models, SHapley Additive exPlanations (SHAP) analysis was applied to both RF and CNN models, which facilitated the convergence of both frameworks on the same discriminatory Raman regions, revealing conserved biochemical determinants of species identity. Complementary MCR-ALS decomposition further resolved the spectra into interpretable biochemical components and provided the rubric for biochemical differentiation. Together, this study aims to demonstrate an end-to-end explainable workflow that couples SERS with interpretable AI, offering a rapid, transparent approach for pathogenic disease diagnosis."

Biological remediation offers genuine mineralization potential but has been constrained by the exceptional stability of carbon-fluorine bonds. Here, we demonstrate that synthetic bacterial consortia assembled through rational genomic design (GENIA) or microfluidic selection (Community G) achieve rapid GenX biodegradation through metabolic complementarity among functionally specialized taxa. Both consortia removed >80% of GenX within 3 days (GENIA: 94.6%; Community G: 80.6%), with defluorination confirmed by fluoride release (82.6 and 69.6%, respectively). First-order kinetic modeling yielded rate constants of k = 0.87 day-1 (GENIA) and k = 0.64 day-1 (Community G), corresponding to half-lives under 1.1 days. Despite pronounced taxonomic divergence, GENIA maintained a stable composition, whereas Community G underwent dramatic restructuring, enriching for specialists of Salmonella, Pseudomonas, and Stenotrophomonas. Comparative genomic analysis revealed functional equivalence, with no significant differences in PFAS-degrading gene content (p = 0.844). Multi-guild community architecture emerged wherein primary degraders (40%-60% abundance) harboring haloacid dehalogenases performed initial C-F bond cleavage, detoxification specialists possessing glutathione S-transferases and fluoride exporters (>90% universal distribution) processed toxic intermediates, and metabolic support taxa enhanced resilience. Molecular docking simulations predicted favorable binding of GenX across phylogenetically diverse dehalogenases (\u0394G = -7.0 to -8.1 kcal/mol), suggesting thermodynamic compatibility with enzymatic catalysis. These results are predictive and computational; docking cannot confirm enzymatic activity or substrate turnover. Experimental validation (enzyme kinetics, purified protein assays) is required. Critically, GENIA activity did not disrupt indigenous soil microbiomes. The data support that GENIA does not cause detectable diversity loss, a necessary but not sufficient condition for ecological compatibility. These findings establish that functional gene diversity, distributed across metabolically complementary taxa through either rational design or adaptive selection, enables efficient PFAS bioremediation, converting recalcitrant \"forever chemicals\" into biodegradable substrates through engineered microbial complexity."

Among their diverse metabolites, hydrogen cyanide (HCN) is traditionally considered a potent antimicrobial compound, yet its broader role in plant-microbe interactions remains underexplored. This study investigated Pseudomonas urmiensis A32, an endophytic bacterium previously shown to enhance drought tolerance and disease resistance in pepper (Capsicum annuum). Whole-genome analysis revealed genes involved in nutrient acquisition, stress protection, and competitive exclusion, including secondary metabolite clusters for carotenoid and HCN biosynthesis. Wild-type A32 showed increased tolerance to oxidative stress, highlighting a redox-active role for HCN. Seed inoculation with A32 reduced disease symptoms and pathogen load in pepper plants challenged with Xanthomonas euvesicatoria, indicating that HCN contributes not only to direct pathogen antagonism but also to modulation of host immune responses. Biochemical analyses showed decreased activity of antioxidant enzymes and increased phenylalanine ammonia-lyase activity. Gene expression analyses revealed upregulation of PR1 and the antimicrobial peptide gene DEF1, indicating enhanced activation of defence genes. These findings demonstrate that HCN acts as a multifunctional metabolite that fine-tunes the balance between reactive oxygen species detoxification and signalling, and integrates microbial biocontrol with host immune priming. In summary, this work highlights the ecological adaptability of P. urmiensis A32 and its potential as an effective bioinoculant for sustainable crop protection."

We determined how two dormancy pathways, ribosome hibernation and the stringent response, contribute to the survival and antibiotic tolerance of Pseudomonas aeruginosa biofilms. Analyses of whole biofilms and single cells showed that these pathways have differing effects on biofilm cell physiology. Ribosome hibernation, mediated by hibernation promoting factor (HPF), is essential for optimal survival and resuscitation of starved biofilm cells. In the absence of HPF, starved cells progressively lose ribosome integrity. However, loss of HPF does not increase the sensitivity of P. aeruginosa biofilm cells to ciprofloxacin or tobramycin. In contrast, the stringent response, mediated by RelA and SpoT, is not required for viability or ribosome integrity in starved biofilm cells, but does affect biofilm antibiotic tolerance. In a plant model of biofilm infection, disruption of either ribosome hibernation or the stringent response reduced bacterial virulence. The results show that ribosome hibernation preserves ribosomal integrity necessary for recovery from starvation and for pathogenesis, while the stringent response is required for growth arrest, antibiotic tolerance, and pathogenesis. These two ribosome-mediated pathways play distinct yet complementary roles in regulating dormancy and persistence of P. aeruginosa biofilms."

Recent evidence demonstrates that non-antibiotic strategies, including bacteriophages, peptide-functionalized nanoparticles, and plant-derived secondary metabolites (e.g., Aloin, citral), provide viable therapeutic alternatives for treating these multidrug-resistant pathogens.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic profile of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* is fundamentally rooted in their capacity to subvert host immunity and endure antibiotic pressure. The literature confirms that disease results from the interaction between microbial factors and host immune responses, a concept termed the Damage Response Framework. Both pathogens exploit similar metabolic and signaling systems, including quorum sensing, to manage colonization and persistence. Emerging evidence from clinical and laboratory studies reveals that bacteriophages isolated from inflammatory environments\u2014such as the gut\u2014exhibit potent bactericidal activity. Furthermore, nanomedicine and bioactive plant compounds demonstrate high efficacy in disrupting biofilm architectures, which conventional antibiotics often fail to penetrate. These non-antibiotic modalities are essential given the rising incidence of carbapenem resistance in these ESKAPE pathogens.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Inflammatory gut environments (e.g., in sepsis models) serve as an untapped reservoir for therapeutic bacteriophages.\n*   \"Green\" nanotechnologies using magnesium or silver nanoparticles display superior antibiofilm capabilities compared to traditional antibiotics in certain experimental rat burn models.\n*   Sub-inhibitory metal stress (e.g., copper) acts as a regulatory signal that reshapes bacterial phenotypes and alters antibiotic sensitivity.\n*   Metabolic crosstalk, such as pyruvate secretion, allows *P. aeruginosa* to manipulate host antioxidant defenses, effectively acting as an immunometabolite.\n*   Explainable Artificial Intelligence (XAI) coupled with SERS provides a rapid, non-invasive method to differentiate between strains based on biochemical biomarkers, circumventing culture-dependent delays.\n*   Computational framework (TACTIC) facilitates the prediction of synergistic drug combinations even in understudied or emerging pathogens.\n*   Genomic design (GENIA) of bacterial consortia allows for the potential biodegradation of persistent compounds like GenX, showing how microbial engineering applies beyond infection to environmental detoxification.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Antimicrobial peptides (AMPs) have emerged as promising therapeutic candidates due to their broad-spectrum activity and low propensity for resistance development. However, conventional discovery approaches remain time-consuming and inefficient for large-scale screening. In this study, we developed an integrated prediction framework that combines deep learning with classical machine learning methods to enable rapid and accurate identification of AMPs. The model was applied to screen over 250,000 artificially generated peptide sequences. Candidate peptides were selected based on physicochemical descriptors and activity-associated features, followed by solid-phase synthesis and minimum inhibitory concentration assays against Pseudomonas aeruginosa. Mechanistic investigations were conducted using scanning electron microscopy to visualize membrane damage, molecular dynamics simulations to probe peptide-membrane interactions, and transcriptomic profiling to assess bacterial stress responses and metabolic pathway alterations. Ten promising antibacterial candidates were successfully identified and experimentally validated. All selected peptides exhibited measurable activity against P. aeruginosa, with several showing potent inhibitory effects. Microscopic and simulation analyses confirmed that the peptides exert their antibacterial effects primarily through membrane disruption. Transcriptomic data further revealed that these peptides interfere with key metabolic pathways and activate bacterial stress response systems. Our findings demonstrate that the integrated deep learning-machine learning pipeline offers an efficient and reliable approach for large-scale AMP discovery. The mechanistic insights gained from this study not only validate the predicted candidates but also provide a foundation for rational optimization of peptide-based therapeutics. This comprehensive strategy holds promise for accelerating the development of next-generation alternatives to conventional antibiotics.\n\nID: 42420824\nTitle: Phenotypic and molecular characterization of carbapenem resistance among clinical isolates of Pseudomonas aeruginosa and Acinetobacter baumannii.\nAbstract: Carbapenem-resistant Pseudomonas aeruginosa (CRPA) and Acinetobacter baumannii (CRAB) were listed on the WHO bacterial priority pathogens list in 2017. These gram-negative bacteria often cause healthcare-associated infections (HAIs), which pose an increasing threat to public health. This study aimed to isolate and identify CRPAs and CRABs from a tertiary care hospital in central Nepal and characterize carbapenem resistance genes at the molecular level. A total of 59 isolates, including 27 Pseudomonas aeruginosa and 32 Acinetobacter baumannii, were collected from different clinical samples from April 2021 to December 2022. Antibiotic susceptibility was determined via the Kirby disc diffusion method. The modified carbapenem inactivation method (mCIM) was used for phenotypic confirmation of carbapenem resistance. Conventional polymerase chain reaction (PCR) was used to detect carbapenem resistance genes. Among the 59 isolates, 76.3% were multidrug resistant (MDR), 63.0% were extended-spectrum beta-lactamase (ESBL), and 62.7% were carbapenem resistant. Among the carbapenem-resistant isolates (n\u2009=\u200937), 75.7% of metallo-beta-lactamase (MBL) producers and 70.3% carried at least one carbapenem resistance gene. The blaCTX-M gene was predominant among the ESBL-positive isolates, present in 58.8% of the P. aeruginosa isolates and 87.5% of the A. baumannii isolates, whereas 29% of both isolates harbored the blaTEM gene. Among the CR-PA isolates, 58.3% carried blaVIM-2, 16.7% carried blaNDM-1, and 8.33% carried blaOXA-23. Among the CR-AB isolates, 56% harbored blaOXA-23, 32% carried blaNDM-1, 16% had both blaNDM-1 and blaOXA-23, and 8% contained both blaOXA-58 and blaOXA-23. This study highlights a significant burden of MDR and carbapenem-resistant P. aeruginosa and A. baumannii, with the co-occurrence of carbapenem resistance genes, in a clinical setting in Nepal. Our findings suggest that active surveillance of antibiotic resistance in pathogens could inform clinicians and healthcare providers about the treatment of infections.\n\nID: 42420271\nTitle: Immune protection and persistence in Pseudomonas aeruginosa infections by pyruvate cross-feeding.\nAbstract: Chronic infections by Pseudomonas aeruginosa in people with cystic fibrosis are characterized by persistent inflammation and oxidative stress, yet the mechanisms enabling bacterial persistence are not fully understood. Here, we identify a persistence mechanism mediated by pyruvate secretion resulting from mutations in the pyruvate dehydrogenase complex in clinical isolates of P. aeruginosa, with putative analogous mutations also identified in Staphylococcus aureus, Haemophilus influenzae and Stenotrophomonas maltophilia. These mutations lead to elevated extracellular pyruvate, which dampens host inflammatory responses and favors bacterial persistence. Pyruvate exerts multiple roles: scavenges reactive oxygen species such as H2O2, suppresses host immune activation both in airway epithelial cells and macrophages, and increases bacterial survival during phagocytosis. This metabolic crosstalk promotes bacterial persistence while reducing epithelial and macrophage inflammatory responses. Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization. This work highlights the broader role of secreted metabolites in host-pathogen interactions and suggests new strategies targeting metabolic pathways to manage chronic infections.\n\nID: 42419644\nTitle: Carbapenem resistance dynamics in clinical Pseudomonas aeruginosa isolates from a tertiary hospital in Valpara\u00edso, Chile, 2019-2024.\nAbstract: Pseudomonas aeruginosa is a major cause of healthcare-associated infections and a World Health Organization priority pathogen because of its marked ability to develop resistance to last-line antibiotics. Carbapenem resistance may arise through chromosomal mutations, acquisition of resistance genes, and clonal dissemination under sustained antimicrobial pressure. To investigate the temporal dynamics of carbapenem resistance in clinical P. aeruginosa isolates from a tertiary-care hospital in Valpara\u00edso, Chile, and to assess their association with antimicrobial consumption. Forty-five clinical isolates recovered between 2019-2024 were analyzed. Antimicrobial susceptibility testing, phenotypic and molecular carbapenemase detection, motility and biofilm assays, and whole-genome sequencing were performed. Sequence types, resistome, virulome, and chromosomal mutations associated with resistance were characterized. Antimicrobial consumption data from the local stewardship programme were evaluated using temporal trend and cross-correlation analyses. Carbapenem non-susceptibility was frequent, and extensively drug-resistant isolates predominated during the pandemic and post-pandemic periods. Resistance was mainly associated with non-carbapenemase-producing isolates and was linked to mutations in oprD, regulators of the MexAB-OprM efflux system, and ampC-related pathways, together with intrinsic OXA-50-like-\u03b2-lactamases. The blaVIM-2 gene was identified in ST408, ST815, and ST253. Temporal clonal turnover was observed, with ST309 emerging as the dominant lineage in 2023-2024. The acquired resistome diversified over time, whereas the virulome remained largely conserved. Higher antimicrobial consumption in intensive care units was associated with carbapenem resistance. Sustained antimicrobial pressure likely contributed to the persistence and replacement of carbapenem-resistant lineages. Integrating genomic surveillance with antimicrobial stewardship may improve detection and control of high-risk hospital clones.\n\nID: 42419610\nTitle: Nanomedicine strategies against multidrug-resistant Acinetobacter baumannii: Delivery, biofilm disruption, and translational considerations.\nAbstract: Acinetobacter baumannii has become a high-priority global problem because it causes hospital-acquired infections and ventilator-associated pneumonia, and multidrug resistance, environmental survivability, and biofilm formation severely restrict therapeutic choices. Antimicrobial nanomedicine has become a major focus as a translational approach. This review critically explores nanotechnology-based interventions for A. baumannii. Multimodal antibacterial and antibiofilm activities have been demonstrated in inorganic nanoparticles, such as silver, gold, and copper-based systems, with an emphasis on their translational therapeutic potential and nano-bio interactions. Polymer- and lipid-based nanocarriers focus on optimising pharmacokinetics, controlled release, and targeted delivery, supporting improved bioavailability and site-specific exposure. Carbon nanomaterials offer alternative antibacterial mechanisms but raise concerns regarding biodegradability and safety. Overall, antimicrobial nanomedicine can be considered an exposure- and delivery-focused system with significant potential for treating persistent drug-resistant A. baumannii infections, highlighting the translational, toxicological, and regulatory challenges relevant to clinical adoption.\n\nID: 42419187\nTitle: Computational framework integrating subtractive proteomics and structural bioinformatics to nominate candidate fungicide targets in Puccinia graminis f. sp. tritici.\nAbstract: Puccinia graminis f. sp. tritici, the causal agent of wheat stem rust, continues to threaten global wheat production through recurring outbreaks and the erosion of host resistance and chemical control efficacy. This study aimed to identify candidate protein targets for fungicide development in P. graminis f. sp. tritici. An integrated subtractive proteomics pipeline was then applied, combining essentiality screening, pathway analysis, structural modeling, and exploratory molecular docking. A stringent filtering strategy excluding proteins homologous to Triticum aestivum, Homo sapiens, and beneficial microbes (Bacillus subtilis, Pseudomonas fluorescens, and Trichoderma harzianum) was applied, thereby maximizing selectivity while minimizing potential off-target ecological effects. From 36,348 proteins, four putative targets were identified: two \u03b2-glucan synthesis-associated KRE6 homologs, a cell wall \u03b1-1,3-glucan synthase (AGS1), and a Major Facilitator Superfamily (MFS) transporter. Guided by intrinsic disorder analysis, AlphaFold2 was used to generate high-quality 3D structural models of the prioritized targets. Network-based functional analysis linked these proteins to core cellular processes, while underscoring that their essentiality in P. graminis f. sp. tritici remains experimentally unconfirmed. Molecular docking with the antifungal agent poacic acid and the nucleotide sugar UDP-glucose suggested potential binding interactions within the predicted cavities. These exploratory simulations present preliminary evidence for plausible small-molecule binding pockets in the selected candidate targets. Collectively, this work provides a multi-layered computational framework for nominating and structurally characterizing candidate targets in wheat stem rust and generates testable hypotheses for future experimental work.\n\nID: 42418271\nTitle: Beyond bacterial communication: host factors that modulate quorum sensing and virulence in human pathogens.\nAbstract: Quorum sensing (QS) coordinates collective bacterial behavior, but during infection, its activity is also shaped by host biology. This review examines how host-derived factors modulate QS-linked virulence in enteric pathogens, Pseudomonas aeruginosa and Staphylococcus aureus. Across these systems, host control operates through three recurring modes: activation or signal mimicry, enzymatic signal degradation, and extracellular sequestration or receptor-level interference. Catecholamines and related metabolites can feed into bacterial sensory pathways and promote virulence signaling; PONs (paraoxonases) and other host enzymes can degrade autoinducers; and lipoproteins, immune mediators, and epithelial surveillance systems can intercept or reinterpret quorum signals. Together, these data support the view that the host is an active signal-processing environment that reshapes colonization, persistence, and tissue damage, and they point to host-inspired anti-virulence strategies that target signaling rather than viability.\n\nID: 42415919\nTitle: Semisynthesis, characterisation, and antibacterial evaluation of a novel lecanoric acid-derived amide library.\nAbstract: The known lichen depside, lecanoric acid (1), was identified as a scaffold of interest for the generation of a unique semisynthetic biodiscovery screening library. Large-scale extraction and isolation on the Australian-sourced lichen Parmotrema tinctorum resulted in the purification of \u22481 g of the desired scaffold 1, along with other known lichen metabolites that included divaricatic acid (2), orcinol (3), orsellinic acid (4), and methyl orsellinate (5). Parallel solution-phase synthesis using amidation chemistry on the abundant scaffold 1 afforded a series of novel amide derivatives 6-13 in high purity (>95%) and low to moderate yields (12-53%). All new semisynthetic compounds were fully characterised following 1D/2D NMR, MS and UV data analysis. Crystalline lecanoric acid was obtained during the chemical investigations of the lichen extract, enabling the first X-ray crystallographic analysis to be undertaken on this depside. Compounds 1-13 were evaluated for antibacterial activity against the human pathogen Pseudomonas aeruginosa using a biofilm inhibition assay. Of the new semisynthetics, amide analogue 12 showed the greatest planktonic cell growth inhibition (13% at 50 \u00b5M), whilst amide analogue 11 was the most active at inhibiting the formation of biofilm (21% at 50 \u00b5M).\n\nID: 42414953\nTitle: Dual antimicrobial and anticancer functions of artemisinin-loaded PEG400-oa nanoparticles: synergistic activity with ciprofloxacin and mechanistic insights from molecular docking.\nAbstract: Artemisinin, a bioactive compound from Artemisia annua with potent antioxidant, antimicrobial and anticancer properties, faces limited clinical utility due to poor solubility and low bioavailability. Given the rising prevalence of multidrug-resistant (MDR) Pseudomonas aeruginosa alternative therapeutic strategies are essential. This study synthesized and characterized artemisinin-loaded micelle/liposome nanoparticles (Art/PEG400-OA NPs) and evaluated their antibacterial, antibiofilm, and anticancer efficacy. Artemisinin was successfully encapsulated within PEG400-OA NPs and characterized via FT-IR, FE-SEM, TEM, TGA, and zeta potential measurements. The nanoparticles exhibited uniform morphology, particle sizes of 40.8\u00a0nm (TEM) and 149.8\u00a0nm (FE-SEM), high encapsulation efficiency (92.14%), and strong thermal and colloidal stability. Synergistic and partial synergistic interactions between Art/PEG400-OA NPs and ciprofloxacin were observed in MDR bacterial samples, significantly inhibiting biofilm formation. Quantitative RT-PCR analysis revealed the downregulation of efflux pump genes (mexA, mexB, mexX, mexY, oprM) and biofilm-associated genes (algD, pelA) following combination therapy. In AGS gastric cancer cells, Art/PEG400-OA NPs induced dose- and time-dependent cytotoxicity (IC\u2085\u2080: 67.75, 62.25 and 54.98\u00a0\u00b5g/mL at 24, 48 and 72\u00a0h), increased apoptosis (31.76% \u00b1 4.2%), and reduced wound-healing migration (56.65% \u00b1 4.26%). Expression analysis demonstrated upregulation of tumor-suppressive miR-34a, and downregulation of its targets (CTNNB1, TGFB1, MMP2 and MMP9). Conversely, miR-181a was downregulated, leading to the upregulation of apoptotic target genes (TP53, CASP8, CASP9). Molecular docking supported strong artemisinin binding to key bacterial and oncogenic proteins. Overall, Art/PEG400-OA nanoparticles represent a potent dual-action nanotherapeutic platform against antibiotic-resistant infections and gastric cancer.\n\nID: 42414940\nTitle: Distinct molecular epidemiology and outcomes of carbapenem-resistant gram-negative infections in Lebanon: insights from the MDRO network.\nAbstract: This study provides the first prospective, genomically validated dataset integrated into the global MultiDrug-Resistant Organism (MDRO) Network from the Middle East and North Africa region. To address the substantial gap in antimicrobial resistance (AMR) data, the American University of Beirut Medical Center (AUBMC) investigated carbapenem-resistant Enterobacterales (CRE), Acinetobacter baumannii (CRAB), and Pseudomonas aeruginosa (CRPA). Consecutive, hospitalized patients whose clinical cultures were positive for CRE, CRAB, or CRPA were prospectively enrolled between June 2018 and November 2019. Data on demographics, hospitalization, outcomes, and antimicrobial susceptibility were collected. Whole-genome sequencing (WGS) characterized the isolates. The primary outcome was the Desirability of Outcome Ranking (DOOR). Ninety-four patients were included: 35 with CRE, 19 with CRAB, and 40 with CRPA. Overall, 30% of patients survived without adverse events, whereas 33% experienced two or more adverse events. Patients with CRAB had the poorest prognosis, with only 5% surviving without complications, and a significantly different DOOR distribution versus CRE or CRPA (p\u2009=\u20090.023). Adjusted DOOR probabilities confirmed the poorer outcomes associated with CRAB: when compared with CRE or CRPA, a randomly selected CRAB patient had only a 37.7% (95% CI, 24.9-52.6%) and 38.8% (95% CI, 26.5-52.7%) probability of achieving a more desirable outcome, respectively. WGS identified blaNDM-5 (24%) and blaOXA-48 (24%) as the most common genes in CRE, blaOXA-23 in all CRAB strains, and blaVIM-2 in 88% of CRPA strains. The dominant clones were CG383 K. pneumoniae (CRE), CG2 (CRAB), and CG111 (CRPA). MDRO infections in Lebanon have distinct molecular patterns compared to the US, Chinese, South American, and Australian cohorts, as well as poor outcomes, especially with CRAB. Ongoing surveillance, strengthening regional collaboration, and future clinical trials are essential to guide diagnostic and therapeutic strategies in settings with increasing AMR.

NCT03646227. 15-08-2018.\n\nID: 42414298\nTitle: Role of starvation survival response mechanisms on ribosome integrity, antibiotic tolerances, and virulence of Pseudomonas aeruginosa biofilms.\nAbstract: Bacterial biofilms contain physiologically diverse subpopulations of cells, including cells that are nutrient stressed or dormant. We determined how two dormancy pathways, ribosome hibernation and the stringent response, contribute to the survival and antibiotic tolerance of Pseudomonas aeruginosa biofilms. Analyses of whole biofilms and single cells showed that these pathways have differing effects on biofilm cell physiology. Ribosome hibernation, mediated by hibernation promoting factor (HPF), is essential for optimal survival and resuscitation of starved biofilm cells. In the absence of HPF, starved cells progressively lose ribosome integrity. However, loss of HPF does not increase the sensitivity of P. aeruginosa biofilm cells to ciprofloxacin or tobramycin. In contrast, the stringent response, mediated by RelA and SpoT, is not required for viability or ribosome integrity in starved biofilm cells, but does affect biofilm antibiotic tolerance. In a plant model of biofilm infection, disruption of either ribosome hibernation or the stringent response reduced bacterial virulence. The results show that ribosome hibernation preserves ribosomal integrity necessary for recovery from starvation and for pathogenesis, while the stringent response is required for growth arrest, antibiotic tolerance, and pathogenesis. These two ribosome-mediated pathways play distinct yet complementary roles in regulating dormancy and persistence of P. aeruginosa biofilms.\n\nID: 42413686\nTitle: Value of the Pitt bacteremia score in predicting the outcome of non-bacteremic patients with infections caused by multidrug-resistant organisms.\nAbstract: Infections caused by multidrug-resistant organisms (MDROs) are increasingly associated with significant morbidity and mortality. Early identification of high-risk patients is essential. The Pitt Bacteremia Score (PBS) is validated in bloodstream infections, but its role in non-bacteremic infections remains unclear. To evaluate the performance of the PBS in predicting mortality among patients with non-bacteremic MDRO infections and compare it with the quick Sequential Organ Failure Assessment (qSOFA) score and the Charlson Comorbidity Index (CCI). We conducted a 5-year retrospective study at a tertiary care center including adults (>18 years) admitted between December 2018 and December 2023 with confirmed non-bacteremic MDRO infections. Organisms included methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), carbapenem-resistant Pseudomonas aeruginosa (CRPA), carbapenem-resistant Enterobacterales (CRE), and carbapenem-resistant Acinetobacter baumannii (CRAB). Patients with bloodstream infection, colonization, ICU stay >48 hours, severe COVID-19, or terminal illness were excluded. Separate multivariable logistic regression models were constructed for PBS, qSOFA, and CCI. Discriminatory performance was assessed using receiver operating characteristic (ROC) curve analysis. Among 202 patients (mean age 62.1 \u00b1 18.3 years; 67.8% male), in-hospital mortality was 21.3%. In multivariable analyses, PBS (aOR 1.75, 95% CI 1.49-2.05; p<0.001) and qSOFA (aOR 11.46, 95% CI 5.37-24.47; p<0.001) remained independently associated with mortality, whereas CCI did not retain statistical significance after adjustment. Age remained an independent predictor in all models, while time to effective antimicrobial therapy was independently associated with mortality in the CCI model (aOR 0.62, 95% CI 0.47-0.81; p<0.001). PBS demonstrated excellent discriminatory performance (AUC 0.939, 95% CI 0.897-0.968), outperforming qSOFA (AUC 0.883) and CCI (AUC 0.696). PBS is a strong predictor of in-hospital mortality in patients with non-bacteremic MDRO infections and demonstrated superior discriminatory performance compared with qSOFA and CCI. These findings support its use as an early risk-stratification tool in this high-risk population.\n\nID: 42413100\nTitle: Respiratory infectious diseases in intensive care units\u2019 patients during 2024, in two hospitals in Guayaquil, Ecuador.\nAbstract: Introduction. Viral, bacterial, and fungal infections represent a major health concern, contributing significantly to increased morbidity and mortality in respiratory diseases. Objective. To characterize respiratory infections and their etiological agents in patients admitted to intensive care units during the first six months of 2024. Materials and methods. An observational, cross-sectional, prospective study was conducted in two hospitals between January 1st. and June 30th., 2024. Clinical and microbiological data were collected (dates, age, sex, type of sample, results, and diagnoses) and analyzed using IBM SPSS\u2122 Statistics 27.0. Results. Of the 56 patients admitted, 35 presented respiratory infections, predominantly in females, with a mean age of 49 years. The following agents were identified: rhinovirus/enterovirus, influenza A, coronavirus, parainfluenza, and respiratory syncytial virus. Among the most frequent bacteria found were: Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, Pseudomonas aeruginosa, Haemophilus influenzae, Enterobacter cloacae, Escherichia coli, Proteus spp., Stenotrophomonas maltophilia, Serratia marcescens, Streptococcus agalactiae and S. pneumoniae. Bacterial resistance genes such as CTX-M, KPC, mecA/mecC, and MREJ, NDM, Oxa48-like, and VIM were also detected. In the case of fungal infections, Candida albicans and Candida glabrata were isolated. Most patients with respiratory illness progressed to hospital-acquired pneumonia. Conclusion. During the study period, respiratory infections in the intensive care units were mainly associated with bacterial pathogens, with a high frequency of hospital-acquired pneumonia and the detection of antimicrobial resistance genes.

Acinetobacter baumannii is an opportunistic pathogen responsible for severe hospital-acquired infections, including bloodstream infections (BSIs). Although major epidemic clones and resistance mechanisms have been described, integrated analyses combining clinical features, patient outcomes and genomic characteristics of BSI isolates remain limited, particularly in China.Gap Statement. Comprehensive analyses integrating clinical outcomes, high-resolution genotyping, capsule locus diversity and their associations with mortality are still lacking.Aim. This study aimed to characterize the clinical characteristics and outcomes of patients with A. baumannii BSIs, as well as the phenotypic and genomic characteristics of the causative isolates. Specifically, we sought to identify high-risk clones and their association with 30-day mortality to improve diagnostic and therapeutic strategies.Methodology. A retrospective cohort study was conducted on 151\u2009cases of A. baumannii BSIs in a tertiary hospital in China. Isolates were analysed using whole-genome sequencing to determine sequence types (STs), capsule loci and resistance and virulence gene profiles.Results. The 151 isolates were classified into 11 different STs using the Pasteur MLST scheme, with ST2Pasteur predominating (88.1%). One isolate represented a novel Pasteur ST (ST2831Pasteur). Using the Oxford MLST scheme, 22 STs were identified, with ST195Oxford, ST208Oxford and ST540Oxford being the most common. Four novel Oxford STs (ST2457Oxford, ST2458Oxford, ST2459Oxford and ST2460Oxford) were identified. Twenty-three capsule locus (KL) types were detected, with KL3 being the most prevalent. Phylogenetic analysis showed clear clustering according to STs and KL types. The ST2Pasteur lineage was characterized by the presence of the OXA-23 gene and carbapenem resistance, as well as an expanded virulence gene repertoire, suggesting enhanced pathogenic potential. The overall 30-day mortality rate was 35.1%. Patients in the death group had shorter hospital stays, fewer surgical interventions and higher rates of complications, invasive procedures and intensive care unit admission. Certain clone combinations, including ST369Oxford-KL9, ST938Oxford-KL210 and ST195Oxford-KL3, were associated with higher mortality rates.Conclusion. ST369Oxford-KL9, ST938Oxford-KL210 and ST195Oxford-KL3 represent high-risk clones associated with A. baumannii BSIs. Early identification of ST and capsule type, alongside clinical risk stratification, may improve diagnosis and guide treatment strategies.\n\nID: 42412424\nTitle: Synthesis of divalent galactosyl and fucosyl spiropyran derivatives for the targeted inhibition of bacterial biofilms.\nAbstract: We developed divalent glycosyl spiropyrans capable of targeted imaging of Pseudomonas aeruginosa that expresses bacterial lectins (LecA and LecB), and which also inhibit biofilm formation via multivalent sugar-lectin interactions.\n\nID: 42412160\nTitle: Lactobacillus strains in the prevention and disruption of antimicrobial-resistance in pathogenic microbial biofilms: a review of mechanisms and clinical perspective.\nAbstract: The growing prevalence of antibiotic resistance, coupled with the heightened drug tolerance exhibited by biofilm-associated infections, represents a major public health challenge and demands the development of innovative therapeutic interventions. Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation. Studies demonstrate robust efficacy of probiotics against clinically challenging pathogens, including methicillin-resistant Staphylococcus aureus, multidrug-resistant Pseudomonas aeruginosa, Clostridioides difficile, Helicobacter pylori, and pathogenic Escherichia coli. Postbiotics, particularly cell-free supernatants and purified bacteriocins, offer standardized, shelf-life probiotic products. Notably, synergistic combinations with conventional antibiotics, phytochemicals, or bacteriophages enhance antimicrobial activity while enabling dose-reduction strategies to mitigate the development of resistance. However, compelling preclinical evidence, clinical translation remains constrained by the imperative for strain-specific characterization, methodologically robust randomized controlled trials, and comprehensive safety validation. This study critically mentions current mechanisms underlying Lactobacillus-mediated anti-biofilm strategies and identifies priority research essential to accelerating clinical application.\n\nID: 42412003\nTitle: Host-directed antimicrobial peptide biomaterials for combating Gram-negative bacterial infections.\nAbstract: Antimicrobial resistance (AMR) represents a defining crisis in modern infectious disease medicine. Gram-negative microbes such as carbapenem-resistant Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae are becoming more resistant than ever. Traditional methods of treatment using antibiotics are ineffective because of the presence of several envelope layers, active efflux pumps, and biofilm production. In contrast, bacteriolytic therapy can exacerbate host immunopathology owing to systemic endotoxin release. Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment; however, clinical use remains hindered by their low stability, high binding to serum proteins, and narrow therapeutic index. In this review, we will discuss the use of biomaterial platforms in the design of peptide-based therapeutics to not only increase their efficacy by reducing peptide clearance but also optimize the immunological environment in which these peptides operate. We will discuss the role of various characteristics, such as surface chemistry, mechanical stiffness, and protein corona, in influencing macrophage polarization and downstream signaling pathways. In addition, we point out a significant limitation within this area of research: many preclinical studies continue to use minimum inhibitory concentration and hemolysis values, which fail to account for the host-directed effects that make these approaches significant. For future progress in this realm, new endpoints are required, along with more clinically relevant animal models and a true incorporation of peptide design into biomaterials engineering.\n\nID: 42411263\nTitle: Dual Sub\u2011MIC Copper-Gentamicin Stress Drives Strain\u2011Specific, Non\u2011Additive Phenotypic Shifts in Pseudomonas aeruginosa.\nAbstract: Exposure to redox\u2011active metals and sub\u2011inhibitory antibiotics represents a significant selective pressure shaping bacterial physiology and antimicrobial susceptibility. Here, we investigated how four genetically and phenotypically distinct Pseudomonas aeruginosa strains respond to sub\u2011MIC copper (Cu) and gentamicin (GE) stress, individually and in combination (Cu\u2009+\u2009GE). Across all strains, Cu acted as the dominant envelope\u2011active stressor, increasing biofilm biomass and extracellular DNA (eDNA) release, suppressing twitching and swarming motility, reducing quorum\u2011sensing\u2011linked protease activity, and enhancing pyomelanin production. GE alone produced limited physiological changes but modulated Cu\u2011driven outputs during co\u2011exposure, including attenuation of Cu\u2011induced eDNA release and strain\u2011specific shifts in motility and pigmentation. Early transcriptional profiling revealed consistent Cu\u2011dependent repression of lasI and mvfR, induction of the metal\u2011responsive regulator czcR, and downregulation of oprD under Cu or Cu\u2009+\u2009GE, corresponding to reduced imipenem inhibition zones when Cu was present during susceptibility testing. Combined Cu\u2009+\u2009GE exposure produced non\u2011additive, emergent effects that diverged from single\u2011stressor responses and varied across strains. These findings demonstrate that sub\u2011inhibitory Cu creates an envelope\u2011centered regulatory landscape into which gentamicin\u2011derived signals are integrated, generating heterogeneous and context\u2011dependent phenotypes. This work underscores the importance of metal-antibiotic interactions in shaping bacterial adaptation and highlights limitations of single\u2011stressor models for predicting antimicrobial behavior in combination.\n\nID: 42410515\nTitle: Antimicrobial resistance profiles of ESKAPE pathogens isolated in a microbiology laboratory in Somalia: a two-year retrospective study.\nAbstract: ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp.) are major causes of healthcare-associated infections and pose a serious public health threat because of their high antimicrobial resistance potential. This study evaluated the distribution, resistance profiles, and associated factors of ESKAPE pathogens isolated in Somalia. This retrospective single-center laboratory-based study was conducted at Mogadishu Somalia T\u00fcrkiye Recep Tayyip Erdo\u011fan Training and Research Hospital, a tertiary care center in Mogadishu, Somalia. Only culture-positive clinical specimens yielding ESKAPE pathogens between January 2024 and December 2025 were included. A total of 2,486 ESKAPE isolates were analyzed. Antimicrobial susceptibility testing was performed using the Kirby-Bauer disk diffusion method according to CLSI criteria. Demographic and clinical data were analyzed using SPSS and R software. Associations between selected demographic and clinical factors and specific pathogens were evaluated using univariate binary logistic regression analysis. Of the isolates, 1,442/2,486 (58.0%) were obtained from male patients, and the most common age group was 18-40 years [952/2,486 (38.3%)]. The most prevalent pathogens were K. pneumoniae [1,033/2,486 (41.6%)] and S. aureus [629/2,486 (25.3%)]. Overall, MDR and XDR phenotypes were detected in 1,633/2,486 (65.7%) and 687/2,486 (27.6%) isolates, respectively. The highest MDR and XDR rates were observed in A. baumannii [135/138 (97.8%) and 97/138 (70.3%)]. High resistance to ceftazidime [128/138 (92.8%)], cefepime [116/138 (84.1%)], ciprofloxacin [115/138 (83.3%)], trimethoprim-sulfamethoxazole [121/138 (87.7%)], and carbapenems [99/138 (71.7%)] was detected in A. baumannii. Susceptibility to vancomycin and linezolid remained largely preserved among Gram-positive pathogens. A. baumannii and Enterobacter spp. were significantly associated with ICU admission, while gender-related differences were observed for P. aeruginosa and S. aureus. A high burden of antimicrobial resistance was observed among ESKAPE pathogens, particularly Gram-negative bacteria, with A. baumannii playing a central role. These findings provide important local surveillance data that may support empirical antibiotic selection, antimicrobial stewardship, and infection control strategies in Somalia.\n\nID: 42409871\nTitle: Fabrication and evaluation of a bi-layered electrospun polyacrylonitrile/polycaprolactone-chitosan/gelatin/polyethylene oxide nanofibers containing antibiotics and nanoparticles: antibacterial and antibiofilm activity.\nAbstract: Bacterial wound infections are among the most frequent infections acquired in healthcare settings. The widespread use and overuse of antibiotics have contributed to the rise of antibiotic-resistant bacterial strains. Thus, it becomes essential to find alternative therapeutic strategies that can both accelerate wound healing and provide potent bactericidal effects. Electrospun nanofiber scaffolds of polycaprolactone (PCL)/polyacrylonitrile (PAN) containing silver nanoparticles (AgNPs) and vancomycin (Van) (Van-Ag-PAN/PCL), chitosan (Cs)/gelatin (Gel)/polyethylene oxide (PEO) containing bioactive glass nanoparticles (BG) and ciprofloxacin (Cip) (Cip-BG-Cs/Gel/PEO) besides a bilayer nanofiber scaffold were fabricated and charachterized. Surface properties, antioxidant activity, and biocompatibility were evaluated using contact angle measurements, antioxidant assays, and hemolysis tests, respectively. The cytotoxicity of the fabricated nanofibers was assessed by MTT assay on the L929 fibroblast cell line. The antimicrobial effectiveness of the fabricated nanofibers against Methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa was investigated in vitro using disk diffusion methods, along with evaluations of biofilm formation inhibition and eradication capabilities.\u00a0The results demonstrated that the electrospun Cip-BG-Cs/Gel/PEO scaffold and bilayer scaffold significantly inhibited one-day biofilm formation of both bacterial strains compared to the control group. Regarding one-day biofilm removal, the Van-Ag-PAN/PCL, Cip-BG-Cs/Gel/PEO and bilayer scaffolds exhibited high efficiency, achieving 66.3%, 68% and 69.3% eradication in MRSA and 34%, 69%, and 70% eradication in P. aeruginosa, respectively. The scaffolds were biocompatible and showed no cytotoxicity on L929 fibroblast cells. Their high antioxidant activity and lack of hemolysis confirm the strong potential of these materials for biotechnological applications.\u00a0The study concludes that the fabricated nanofibers effectively inhibit bacterial biofilm formation by MRSA and P. aeruginosa. Their strong antibacterial properties suggest potential use in reducing hospital-acquired infections and in applications such as drug delivery, tissue regeneration, and wound dressings, due to their controlled and sustained release of bioactive compounds for improved therapeutic outcomes.\n\nID: 42409517\nTitle: Synergistic inhibition mechanism of slightly acidic electrolyzed water combined with \u03b5-polylysine hydrochloride against Pseudomonas fluorescens.\nAbstract: This study explored the synergistic inhibition mechanism on combining slightly acidic electrolyzed water (SAEW) and \u03b5-polylysine hydrochloride (\u03b5-PLH) against Pseudomonas fluorescens, a key spoilage bacterium in aquatic products. A significant synergistic antibacterial effect was achieved with the fractional inhibitory concentration index being 0.5 when the two agents were combined at their respective 1/4 of minimum inhibitory concentration. Mechanistic studies revealed that the combined treatment severely disrupted bacterial membrane integrity and potential, inhibited biofilm formation, and caused extensive cell lysis in P. fluorescens PF08. Fourier transform infrared spectroscopy further indicated that the combined treatment caused the most severe damage to cell wall peptidoglycan, proteins, and polysaccharides. Non-targeted metabolomics disclosed that SAEW primarily disturbed histidine and lysine metabolisms, while \u03b5-PLH interfered with arginine and glutathione metabolisms, and their combination triggered broader metabolic reprogramming in the strain, demonstrating a multi-target antibacterial mechanism. This study provides a theoretical basis for the application of the SAEW-\u03b5-PLH composite green antibacterial agent in the preservation of aquatic raw materials and their prefabricated meal products which is perishable due to contamination by P. fluorescens.\n\nID: 42409485\nTitle: Analysis of the antibacterial mechanism and antivirulence efficacies of citral against Shewanella putrefaciens and Pseudomonas fluorescens in mono- and co-culture.\nAbstract: Shewanella putrefaciens and Pseudomonas fluorescens, as significant specific spoilage organisms in aquatic products, can regulate cell density and a variety of physiological processes through quorum sensing (QS). This research examined the antibacterial mechanism and antivirulence efficacies of citral (CT), as a quorum sensing inhibitor (QSI), against S. putrefaciens and P. fluorescens in mono- and co-culture. Furthermore, the application of CT to large yellow croaker preservation was investigated. Results revealed that CT exerted its antibacterial activities in a dose-dependent manner. CT increased intracellular oxidative stress levels and malondialdehyde (MDA) content, decreased ATP content and peroxidase activity, and promoted the damage of cell membrane, especially in S. putrefaciens group. These two bacteria had a synergistic effect in causing spoilage through biofilm formation and motility. The antivirulence efficacies of CT against the co-culture group were weaker than those of in the mono-culture groups. CT was also found to suppress the expression of key virulence regulators in S. putrefaciens and P. fluorescens virulence, including Autoinducers-2 (AI-2) production in the QS system. Furthermore, CT had the potential capability in the preservation of large yellow croaker. Consequently, these results proved CT could combat bacteria and had antivirulence efficacies against S. putrefaciens and P. fluorescens in mono- and co-culture.\n\nID: 42409196\nTitle: Multimodal, quantitative analysis enables process management of productive, mixotrophic biofilms.\nAbstract: Biofilms offer attractive opportunities for continuous biotechnological production processes; however, understanding biomass dynamics and electron fluxes within such communities remains a major challenge for process optimization and scale-up. In this study, a segmented-flow tubular capillary biofilm reactor was investigated using a dual-species consortium of Pseudomonas taiwanensis and Rhodopseudomonas palustris for nitrogenase-driven hydrogen production. Biofilm development and biomass dispersion were monitored using a newly established flow cytometry-based analysis pipeline capable of quantifying the abundance of the different organisms in the reactor outflow. Mature biofilms operated under N2-limited conditions exhibited stable species composition and cell numbers over a 72\u202fh monitoring period, indicating semi-steady-state conditions characterized by slow growth and continuous erosive dispersion. Hydrogen production was strongly influenced by reactor gas composition. Unexpectedly, strictly anaerobic operation did not maximize hydrogen evolution. Instead, the addition of small amounts of O2 (\u22641\u202f%) significantly enhanced hydrogen production, likely by supporting the growth of the aerobic partner Pseudonomas taiwanensis, which stabilizes the biofilm structure and maintains favorable microoxic conditions. Hydrogen production declined in mature biofilms with high biomass accumulation, consistent with growth-coupled nitrogenase activity. To address this limitation, controlled biofilm dispersion was implemented by temporarily interrupting nutrient supply, inducing biofilm sloughing followed by rapid regrowth. This strategy restored high hydrogen production rates and enabled cyclical production phases while maintaining continuous reactor operation. Electron balance analysis further revealed substantial unaccounted electron fluxes, suggesting significant biofilm-associated maintenance energy demands. These results highlight the importance of biofilm management strategies for improving productivity and process control in biofilm-based production systems.\n\nID: 42409126\nTitle: Arginine metabolism and compensatory adaptations expand the impaired phage resistance repertoire in colistin-resistant Acinetobacter baumannii.\nAbstract: Limiting the emergence of phage resistance is a key priority in optimizing phage therapy. However, it remains poorly understood whether the development of antibiotic resistance influences the evolution of phage resistance. To investigate phage-host interactions, we used both colistin resistant strains derived from the wild-type and genetically engineered knockout mutants. Transcriptomic analysis was employed to examine the adaptive responses of these colistin-resistant mutants under phage pressure. Finally, we characterized the phage-resistant variants that evolved in the colistin-resistant backgrounds. Our results demonstrate that the emergence of phage-resistant variants was significantly reduced in colistin resistant mutants. These phenotypic changes were primarily mediated by disruption of lpxC and lpxD, with additional effects from compensatory mutations and amino acid metabolism. The \u0394lpxC and \u0394lpxD mutants exhibited distinct transcriptional profiles and metabolic features under phage pressure. The astA-mediated arginine metabolism pathway was a key modulator of phage-colistin-resistant mutant interactions. In the \u0394lpxD background, Mla system inactivation and arginine supplementation accelerated the phage resistance evolution (including via the mucoid phenotype). Capsule defects arising during phage resistance development in both \u0394lpxC and \u0394lpxD mutants simultaneously increased colistin susceptibility. Overall, lpxC/lpxD disruption constrains phage resistance evolution in A. baumannii. Compensatory mutation and bacterial metabolism not only mitigate fitness cost and maintain antimicrobial resistance but also expand evolutionary trajectories of bacteria under phage pressure. These findings reveal the adaptive mechanisms of colistin-resistant A. baumannii under phage selection and support the optimization of phage therapy.\n\nID: 42407157\nTitle: CRISPR-based diagnostics for ESKAPE drug-resistant bacteria: From proof-of-concept to point-of-care.\nAbstract: The ESKAPE pathogens, including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species, represent a major challenge in the antimicrobial resistance (AMR) crisis. These pathogens are progressively acquiring pan-resistance and spreading beyond traditional healthcare settings, yet conventional diagnostic methods remain ill-equipped for point-of-care (POC) deployment due to slow processing times and limited adaptability. CRISPR/Cas systems feature programmable target specificity and intrinsic signal amplification, enabling rapid and accurate nucleic acid detection. Despite these advantages, the translation of CRISPR-based assays for ESKAPE pathogens from proof-of-concept to practical POC tools faces major challenges. Current research is fragmented, and key trade-offs between sensitivity, multiplexing performance and operational simplicity have not been fully addressed. This review offers a critical assessment of the field, moving beyond a simple summary of existing studies to analyze how various CRISPR systems (Cas9, Cas12, Cas13, and Cas14) and amplification strategies address the demands of POC testing. We identify key barriers to clinical application, particularly sample preparation, multiplex detection, reagent stability, and discuss emerging solutions such as microfluidic integration, lyophilized reagents development, and artificial intelligence-driven data interpretation. By focusing on the central question of how to transition from benchtop research to bedside application, this review provides a strategic framework for advancing next-generation CRISPR diagnostics capable of rapid, precise, and real-time detection of drug-resistant ESKAPE pathogens in the fight against AMR.\n\nID: 42406312\nTitle: Genomic landscape of 340 virulent Acinetobacter bacteriophages reveals anti-CRISPR-enriched candidates for therapeutic prioritization.\nAbstract: Carbapenem-resistant Acinetobacter baumannii (CRAB) represents a critical global health threat for which existing antibiotics are increasingly inadequate. This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates. We performed large-scale comparative genomic analysis of 340 virulent Acinetobacter bacteriophages, integrating phylogenetic reconstruction, pangenome analysis, CRISPR spacer-based host interaction mapping, Anti-CRISPR protein identification, and systematic antimicrobial resistance (AMR) gene screening. Genome sizes spanned a nearly 20-fold range, with a significant negative correlation between genome size and GC content (R\u00b2 = 0.139, \u03c1 = -0.630). Phylogenetic analysis revealed extensive divergence across multiple lineages with no dominant clade. Pangenome analysis identified 20,982 unique protein families, of which 76.2% were cloud genes, confirming a highly open genome architecture. CRISPR spacer matching yielded 1,480 high-confidence matches across 100 phage genomes, providing molecular evidence of broad historical infectivity. Anti-CRISPR profiling identified Acinetobacter phage XC1 as an exceptional therapeutic candidate harboring 55 predicted Anti-CRISPR proteins with canonical regulatory locus architecture. AMR screening identified 21 distinct AMR gene homologs (Loose RGI hits, 22.5 to 47.1% amino acid identity) distributed heterogeneously across the dataset, confirming abundant therapeutically clean candidates while flagging a subset warranting further scrutiny before therapeutic exclusion. These findings provide a multi-criteria genomic framework for rational phage candidate prioritization against multidrug-resistant Acinetobacter infections, with direct implications for evidence-based phage therapy development.\n\nID: 42406057\nTitle: Aloin of Aloe vera disrupts pseudomonas aeruginosa biofilm formation: exploring nutritional therapeutics.\nAbstract: Pseudomonas aeruginosa is responsible for several infections due to its remarkable antibiotic resistance, facilitated by its ability to form biofilms. In this study, Aloin, an anthraquinone present in the plant Aloe vera, was tested for antibiofilm activity against P. aeruginosa PAO1. Aloin demonstrated efficient biofilm-inhibiting capacity at a sub-MIC dose of 4.8 mM, along with/without GEN at 0.002\u00a0\u00b5g/\u00b5L (sub-MIC), in an additive manner, determined by the FICI test. Furthermore, it reduced biofilm-associated carbohydrates by 66.9%, proteins by 66.22%, and extracellular DNA by 69.57%. In silico analysis revealed that Aloin interacts with key P. aeruginosa proteins, such as RhlI (Glide Score: -6.035\u00a0kcal/mol; Glide e-model score: -60.414\u00a0kcal/mol), LasI (Glide Score: -4.407\u00a0kcal/mol; Glide e-model score: -35.286\u00a0kcal/mol), LasR (chain A) (Glide Score: -3.764\u00a0kcal/mol; Glide e-model score: -36.012\u00a0kcal/mol), LasR (chain B) (Glide Score: -5.015\u00a0kcal/mol; Glide e-model score: -46.672\u00a0kcal/mol), PqsR (Glide Score: -4.701\u00a0kcal/mol; Glide e-model score: -25.491\u00a0kcal/mol), PelA (Glide Score: -6.097\u00a0kcal/mol; Glide e-model score: -53.723\u00a0kcal/mol), and PelB (Glide Score: -5.043\u00a0kcal/mol; Glide e-model score: -53.128\u00a0kcal/mol) by forming strong hydrogen bonds. In silico simulation studies also substantiated the Aloin-protein binding results. The production of virulence factors, such as exoprotease and pyocyanin, was reduced by 71% and 74%, respectively. Furthermore, CLSM and SEM analysis showed a decrease in biofilm thickness from 498\u00a0\u03bcm to 72\u00a0\u03bcm and a reduced denser structure in the presence of Aloin. These results suggest that Aloin from Aloe vera has the potential to be an effective biofilm inhibitor without toxicity, with broad applicability.\n\nID: 42405335\nTitle: Antimicrobial resistance in dental unit waterlines: a scoping review of microbial diversity, resistance patterns, and knowledge gaps.\nAbstract: Antimicrobial resistance (AMR) is a growing global health threat, and dental unit waterlines (DUWLs) may contribute to AMR, as DUWLs provide ideal conditions for biofilm development and growth of antimicrobial-resistant microorganisms. However, the microorganisms involved and their resistance patterns in DUWLs remains unclear. This scoping review aimed to map the available evidence on antimicrobial-resistant microorganisms in DUWLs and characterize resistance patterns. We conducted a systematic literature search across the PubMed, Scopus, and Web of Science databases up to March 2026. Studies that reported the isolation of microorganisms from DUWLs and AMR using phenotypic methods and/or genotypic detection of antimicrobial resistance genes (ARGs) were included. Data were extracted and summarized descriptively. A total of 18 studies were included. Most studies analyzed DUWL water samples and reported bacterial isolates, particularly Gram-negative organisms such as Pseudomonas spp. Phenotypic antimicrobial susceptibility testing was performed in 16 studies, with \u03b2-lactams, aminoglycosides, and fluoroquinolones being the most frequently evaluated classes. Ciprofloxacin and gentamicin were the most commonly tested antibiotics. AMR was reported in 15 studies, with frequent resistance to \u03b2-lactams and multidrug resistance. Fungal microorganisms showed reduced susceptibility in biofilms compared to planktonic forms. Genotypic data were limited, and no ARGs were detected in the two studies that assessed them. DUWLs can become sources of antimicrobial-resistant microorganisms. However, the current evidence remains limited due to methodological variability and insufficient genotypic data. Future research should integrate both phenotypic and genotypic approaches, include biofilm-specific analyses, and evaluate the impact of DUWL management and antimicrobial stewardship strategies within a One Health framework. Open Science Framework (OSF) https://doi.org/10.17605/OSF.IO/P3X5D.\n\nID: 42404764\nTitle: Comparative analysis of treatment outcomes and risk factors associated with different combination antimicrobial regimens in patients with multidrug-resistant Acinetobacter baumannii pneumonia.\nAbstract: Multidrug-resistant Acinetobacter baumannii (MDRAB) pneumonia is a major cause of mortality in hospital-acquired infections due to extensive drug resistance and limited therapeutic options. Optimizing treatment and identifying mortality-related factors are urgently needed. To compare the efficacy of different antibacterial regimens in MDRAB pneumonia and determine independent risk factors for 28-day all-cause mortality. This single-center retrospective cohort study included 142 MDRAB pneumonia patients from February 2022 to February 2025. Patients were divided into three groups: Group A, sulbactam-containing combinations (n = 63); Group B, polymyxins + tigecycline (n = 45); Group C, other regimens (n = 34). Outcomes included bacterial resistance patterns, 28-day mortality, dynamic PCT and CRP levels, APACHE II and SOFA scores, and lymphocyte subsets. Multivariate logistic regression identified mortality predictors. Group A showed the lowest resistance to cefoperazone/sulbactam (30.16%) and the highest sensitivity (71.43%, both P< 0.05). Group B had the highest tigecycline resistance (31.11%). The 28-day mortality rates were 39.68% (A), 60.00% (B), and 64.71% (C) (P\u00a0=\u00a00.028). Independent mortality predictors were APACHE II, SOFA, and CD4+/CD8+ ratio (all P< 0.01). On day 7, Group A had the lowest PCT, while Group C showed the smallest declines in PCT and CRP. Group A exhibited the highest CD4+/CD8+ ratio. Sulbactam-based combination therapy was associated with improved pathogen clearance and survival in this retrospective cohort. Mortality is closely linked to initial disease severity and early organ dysfunction. Dynamic changes in PCT and CD4+/CD8+ ratio have significant prognostic value.\n\nID: 42404584\nTitle: Pseudomonas aeruginosa Virulence Bacteriophage Isolated From Inflammatory Mouse Feces Exhibits Bactericidal Activity in Infected Wounds of a Mouse Model.\nAbstract: Recently, bacteriophages have risen as a potent therapy for superbug infections. The mammal gut demonstrates an interesting source of virulence bacteriophages. The gut with inflammation is phage-rich; therefore, we primarily aimed to prove the concept that an inflammatory gut is a possible source of effective phages and to evaluate the efficacy of the candidate phage against Pseudomonas aeruginosa in vitro and in a mouse model of infected wounds. The gut microbiome of cecal ligation and puncture (CLP) sepsis mice, an animal model of inflammation, showed a dominant presence of Podoviruses. CLP bacteriophages (CLP \u03a61-\u03a64), of which the CLP \u03a64 possessed the broadest bactericidal activity (viable bacterial cell reduction in time-kill study) against P. aeruginosa isolates. The CLP \u03a64 specifically killed the Pseudomonas aeruginosa clinical (PACL) strain with two huge burst events. Although the CLP \u03a64 had no effect on ex vivo mouse bone marrow-derived macrophage (BMDM) cytokine gene expression and cytokine production, the CLP \u03a64 attenuated the severity of the P. aeruginosa-infected wound mouse model after treatment. P. aeruginosa PACL exhibited significantly pathogenic characteristics in a mouse model, including excessive bacterial loads (in wounds and internal organs, indicating the systemic infection due to localized infected wound with P. aeruginosa), increased IL-6 cytokine (in serum), upregulated IL-6 expression (in wounds), and immune cell infiltration (in wounds), indicating severe inflammation. In the CLP \u03a64 treatment alone, the wound tissues upregulated IL-10 expression and recruited inflammatory cells. Interestingly, the three-day CLP \u03a64 treatment was adequate to eradicate P. aeruginosa PACL in the wounds and other internal organs. After treatment, the mouse serum cytokine showed a remarkably decreased IL-6. Likewise, IL-6 downregulation and IL-10 upregulation were demonstrated in the treated wounds, suggesting an anti-inflammatory shift. These results demonstrated the effectiveness (bacterial wound and internal organ clearance and cytokine modulation) of the CLP \u03a64 in the P. aeruginosa-infected wound and systemic infection. Finally, the CLP \u03a64 isolation verified a proof of concept that the irritated gut acts as a source of bacteriophages. The gut virome was a promising and interesting source of antimicrobial and immunomodulating bacteriophage.\n\nID: 42420327\nTitle: Pulmonary mRNA-LNP vaccines for rapid and durable protection against bacterial infection.\nAbstract: Pulmonary bacterial infections remain a major clinical challenge. Although vaccination reduces infection rates and mortality, the vulnerable post-vaccination immunity gap can still result in infection and vaccine failure. In addition, effective vaccines are unavailable for many clinically important bacterial pathogens. Here, we report a pulmonary mRNA-lipid nanoparticle (mRNA-LNP) vaccine incorporating an ionizable lipid engineered for localized high-level expression, which elicits both rapid and durable protection against bacterial lung infections in female mice, effectively bridging this critical window of vulnerability. Intratracheal delivery of mRNA-LNP rapidly primes lung neutrophils and macrophages into a transcriptionally pre-activated state, enhancing their phagocytic activity and enabling rapid, antigen-independent bacterial clearance during the early post-vaccination period (approximately 1-7 days). Subsequently, vaccination induces potent antigen-specific adaptive responses, conferring sustained protection against both laboratory and clinical drug-resistant Pseudomonas aeruginosa strains. Single-cell transcriptomics and immune profiling reveal coordinated activation of innate and adaptive immune programs. This dual-phase immune response exemplifies a paradigm-shifting vaccine design that integrates innate and adaptive immunity to confer both immediate and long-term protection. Our findings establish a mechanistic basis for rapid antibacterial defense and highlight pulmonary mRNA-LNP vaccination as a promising strategy for combating respiratory infections.\n\nID: 42419871\nTitle: Ambient temperature variations and antimicrobial resistance: a multicountry analysis of non-linear relationships and temperature thresholds.\nAbstract: Antimicrobial resistance (AMR) is an escalating global health crisis being worsened by climate change. Studies of temperature-AMR associations remain limited by geographic scope, time frames and linear approaches. We aimed to identify temperature thresholds where AMR dynamics shift across pathogen-drug combinations, periods and socioeconomic contexts. We analysed data from 56 countries and territories over 24 years (1999-2022), focusing on six WHO-designated 'critical' antibiotic-resistant pathogens. Using segmented regression models with mean ambient temperature as the primary independent variable, we divided the study period into three intervals (1999-2006, 2007-2014, 2015-2022)\u2009and incorporated 16 socioeconomic and environmental covariates. Model robustness was validated through bootstrap cross-validation with 1000 resamples. We identified distinct temperature association thresholds for each pathogen-drug combination (5.7\u00b0C-18.4\u00b0C). Below these thresholds, resistance rates consistently decreased with rising temperatures; above thresholds, responses varied by phenotype and time period. For third-generation cephalosporin-resistant Escherichia coli, each 1\u00b0C rise above 16.5\u00b0C corresponded to a 0.46% increase (95%\u2009CI 0.28% to 0.65%; p<0.001) during 1999-2006, a 0.11% decrease (95%\u2009CI -0.17% to -0.06%; p<0.001) during 2007-2014 and a 0.18% increase (95%\u2009CI 0.11% to 0.25%; p<0.001) during 2015-2022. The Corruption Perception Index showed consistent negative associations with resistance rates, particularly for carbapenem-resistant Acinetobacter baumannii (\u03b2=-1.40, p<0.001). Phenotype-specific temperature association thresholds provide descriptive, hypothesis-generating reference points for understanding how AMR burden varies along the global temperature gradient. The observed temporal heterogeneity suggests complex patterns requiring long-term monitoring and climate-adaptive AMR control strategies considering both phenotype-specific temperature sensitivities and socioeconomic contexts.\n\nID: 42419643\nTitle: Molecular characteristics and antimicrobial susceptibility profiling of carbapenem-resistant Pseudomonas aeruginosa clinical isolates in Korea: Implications for novel \u03b2-lactam therapy.\nAbstract: This study investigated the molecular epidemiology, cross-resistance to novel antibiotics, and clonal distribution of carbapenem-resistant Pseudomonas aeruginosa (CRPA) clinical isolates. Forty-three CRPA isolates were collected from sterile clinical specimens in the Republic of Korea (ROK) between 2015 and 2025. Susceptibility to 14 antibiotics was assessed in vitro by broth microdilution. Carbapenem-resistance mechanisms were characterized by using polymerase chain reaction (PCR), real-time quantitative reverse transcription PCR (RT-qPCR), and sequencing. Clonal diversity and epidemiological trends were examined by multilocus sequence typing (MLST). Among the 43 CRPA isolates, the susceptibility rates were 88.4% for both aztreonam-avibactam and cefiderocol, compared with 46.5% for ceftolozane-tazobactam and 39.5% for ceftazidime-avibactam. Among the 22 difficult-to-treat resistance (DTR) P. aeruginosa isolates, susceptibility rates were 77.3% for aztreonam-avibactam and 86.4% for cefiderocol. Carbapenemase genes were detected in 46.5% of isolates, predominantly blaNDM (41.9%). Porin loss and efflux pump overexpression were observed in 83.7% and 23.3% of isolates, respectively. Among the 22 P. aeruginosa isolates non-susceptible to both ceftolozane-tazobactam and ceftazidime-avibactam, 90.9% and 77.3% remained susceptible to aztreonam-avibactam and cefiderocol, respectively. MLST identified 12 sequence types (STs), with predominance of ST773 and ST644, both carrying blaNDM. CRPA exhibited multifactorial resistance driven by oprD disruption and blaNDM carriage within a diverse clonal structure dominated by ST773 and ST644. Aztreonam-avibactam and cefiderocol showed promising activity, supporting their role as critical therapeutic options.\n\nID: 42419223\nTitle: Viscum album subsp. austriacum-mediated biosynthesis of magnesium nanoparticles: In vitro anticancer, antibiofilm, and antioxidant activities with computational validation.\nAbstract: Viscum album L. (European mistletoe) is a medicinally significant hemiparasitic plant with a rich bioactive phytochemical profile. Despite growing interest in its pharmacological properties, studies integrating nanoparticle biosynthesis, comprehensive biological evaluation, and computational analysis remain scarce for its austriacum subspecies. In this study, magnesium nanoparticles (VA-MgNPs) were green-synthesized using the ethanol extract of Viscum album subsp. austriacum as a bioreducing and capping agent, and their biological activities were comparatively assessed alongside the crude extract and Mg(NO3)2\u00b76H2O precursor control. LC-HR/MS analysis identified quinic acid (10,027.49\u202f\u03bcg/g) and chlorogenic acid (5294.12\u202f\u03bcg/g) as the dominant phenolic constituents. The synthesized VA-MgNPs were characterized by FT-IR, UV-Vis, FE-SEM, TEM, and XRD analyses, confirming nanocrystalline formation with a mean crystallite size of approximately 66.47\u202fnm. Antioxidant evaluation using DPPH, ABTS, and FRAP assays revealed that the crude extract retained superior radical scavenging capacity, which is attributed to the consumption of free phenolic hydroxyl groups during nanoparticle formation. In contrast, VA-MgNPs demonstrated markedly enhanced anticancer activity against breast (MCF-7: IC50\u202f=\u202f124\u202f\u03bcg/mL; MDA-MB-231: IC50\u202f=\u202f96\u202f\u03bcg/mL) and colorectal (HCT116: IC50\u202f=\u202f105\u202f\u03bcg/mL; HT-29: IC50\u202f=\u202f135\u202f\u03bcg/mL) cancer cell lines, with lower cytotoxicity toward non-tumorigenic cells, indicating selective antiproliferative action. Although antibacterial activity was limited across tested strains, VA-MgNPs exhibited significant antibiofilm activity, achieving up to 75% inhibition against Pseudomonas aeruginosa. Molecular docking simulations revealed that chlorogenic acid and its magnesium complex displayed strong binding affinities toward antioxidant- and antimicrobial-related protein targets, with binding energies reaching -8.5\u202fkcal/mol, mechanistically supporting the observed biological activities. These findings demonstrate that VA-MgNPs are a promising nanotherapy platform, particularly for antibiofilm and anticancer applications.\n\nID: 42417318\nTitle: [Spectrum of pathogens and their antimicrobial resistance in cystitis, pyelonephritis, and prostatitis].\nAbstract: Infectious and inflammatory diseases of the genitourinary tract account for approximately 42% of all outpatient urology cases, and disorders such as cystitis, pyelonephritis, and prostatitis are often characterized by a chronic, recurrent course. One of the key contributors to recurrent urinary tract infections is inappropriate therapy that does not take into account the local microbial spectrum and pathogen resistance profiles. To determine the spectrum of uropathogens and their antimicrobial resistance patterns in patients with cystitis, pyelonephritis, and prostatitis. We analyzed the results of microbiological urine cultures from outpatient urology patients processed by the Invitro Laboratory between 2022 and 2024. In total, 4031 bacterial isolates were included: 2903 (72.0%) from patients with cystitis, 1017 (25.2%) from patients with pyelonephritis, and 111 (2.8%) from patients with chronic prostatitis. The structure of the microbial landscape differed by diagnosis. E. coli was the predominant pathogen in all groups, with a detection rate of 73.8-75.3% in cystitis and pyelonephritis, while in chronic prostatitis the rate was markedly lower at 53.1%. Klebsiella pneumoniae and Enterococcus faecalis were more frequently isolated in prostatitis (19.0% and 15.3%, respectively) compared with urinary infections, where their combined frequency ranged from 6.9% to 11.9%. Other pathogens (Proteus mirabilis, Streptococcus agalactiae, Enterobacter cloacae, Pseudomonas aeruginosa) accounted for 6.4% of isolates in cystitis, 7.6% in pyelonephritis, and 12.6% in prostatitis. Antimicrobial resistance was assessed for E.coli isolates. Resistance to amoxicillin/clavulanate was 24.9% in cystitis, 31.0% in pyelonephritis, and 38.9% in prostatitis. Levofloxacin resistance was observed in approximately one third of isolates from cystitis and in about half of isolates from pyelonephritis, whereas all E.coli isolates from prostatitis cases were susceptible. Resistance to trimethoprim-sulfamethoxazole in prostatitis was approximately twice as high as in cystitis and pyelonephritis. Urinary tract infections are predominantly caused by E.coli, while chronic prostatitis is associated with a more diverse spectrum of pathogens, with E.coli detected in only 53.1% of cases. Antimicrobial resistance profiles differ substantially between urinary infections and prostatitis, underscoring the importance of tailoring empirical therapy to local pathogen distribution and resistance patterns.\n\nID: 42417296\nTitle: [Carbapenem-resistant urinary tract infection in patients with nephrolithiasis].\nAbstract: Carbapenems belong to reserve antibiotics; however, the frequency of carbapenem-resistant bacterial strains is increasing in hospitals. Resistance of nosocomial Gram-negative strains to carbapenems is a significant problem with a tendency to progress, necessitating close attention to it. Analysis of the prevalence of carbapenem-resistant flora in a urology clinic, identifying the most significant factors associated with the resistance of pathogens to medications. A single-center retrospective study was conducted analyzing 1,720 urine culture results from patients with nephrolithiasis managed at a tertiary care institution in Moscow. Acquired carbapenem resistance to at least one carbapenem was detected in 5.4% of patients. Carbapenem-resistant Klebsiella pneumoniae (70% of all carbapenem-resistant isolates) and Pseudomonas aeruginosa (13%) were the most frequently identified species. Male sex and age >50 years were identified as significant risk factors. A logistic regression model was constructed to quantify the contribution of major risk factors, demonstrating an area under the receiver operating characteristic curve (ROC-AUC) of 0.88. The relatively high prevalence of carbapenem-resistant Gram-negative urinary tract infection among patients hospitalized for urological management of nephrolithiasis necessitates further research to identify optimal therapeutic strategies and prevent postoperative infectious complications caused by these pathogens. Moreover, the prevalence rate of carbapenem-resistant bacteria (5.4%) carries important implications for antimicrobial stewardship and pharmaceutical resource allocation in urological inpatient settings.\n\nID: 42414423\nTitle: Green synthesis of tetrahydropyridine-3-carboxylate derivatives and evaluation of antimicrobial and antimalarial activities supported by molecular docking, POM studies, and drug-likeness analysis.\nAbstract: A series of novel haloarene-decorated tetrahydropyridine derivatives B(1a-1f) were synthesized via a simple, environmentally benign one-pot multicomponent reaction employing ethanol as a green solvent and [Et\u2083NH][HSO\u2084] as a Br\u00f8nsted acid ionic liquid catalyst. The reaction utilized methyl acetoacetate (1 mmol), substituted aromatic aldehydes (2 mmol), and substituted anilines (2 mmol) at 60\u00a0\u00b0C to afford the desired compounds. All compounds were evaluated for their in vitro antimicrobial activity against three fungal strains (Candida albicans, Aspergillus niger, and Aspergillus clavatus), two Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa), and two Gram-positive bacteria (Staphylococcus aureus and Streptococcus pyogenes), using the serial broth dilution method. Additionally, their antimalarial potential was assessed against chloroquine- and quinine-sensitive 3D7 and multidrug-resistant Dd2 strains of Plasmodium falciparum. Among the synthesized derivatives, compounds B1a, B1b, and B1b exhibited the most potent antimicrobial and antimalarial activities. Molecular docking studies revealed that compound B1f showed the highest binding affinity toward S. aureus nucleoside diphosphate kinase, with a predicted free binding energy of -\u2009913\u00a0kcal/mol. Pharmacological profiling suggested favorable drug-like properties and non-toxic behavior. These findings highlight haloarene-decorated tetrahydropyridine derivatives as promising dual-action candidates with potential to combat both bacterial and malarial infections.\n\nID: 42414059\nTitle: Sepsis Presenting as Hyperleukocytosis Mimicking Congenital Leukemia in a Preterm Neonate: A Case Report.\nAbstract: Neonatal sepsis continues to be a leading cause of mortality, frequently presenting with vague clinical characteristics. Rarely, it might present with hyperleukocytosis, which closely resembles congenital leukemia and creates a diagnostic difficulty. A preterm male neonate born at 34 weeks' gestation with a birth weight of 1.8 kg was delivered to a 27-year-old G2, P1 woman in a nonconsanguineous marriage. The neonate developed respiratory distress shortly after birth. Laboratory evaluation revealed a total leukocyte count of 108 \u00d7 103/\u00b5L (108 \u00d7 109/L), raising concern for congenital leukemia. However, peripheral blood smear showed cytoplasmic vacuolation and toxic granules without any blast cells, and flow cytometry excluded malignancy and leukocyte adhesion deficiency. Blood culture grew Acinetobacter baumannii A diagnosis of sepsis-induced hyperleukocytosis was made. The leukocyte count normalized with broad-spectrum antibiotics, and the neonate recovered fully. Hyperleukocytosis in neonates is not always indicative of congenital leukemia. Differentiating between malignant and reactive causes is crucial as management and prognosis differ widely.\n\nID: 42413502\nTitle: TACTIC: A transfer learning framework to predict drug interactions in emerging pathogens.\nAbstract: Machine learning (ML) is necessary to efficiently identify potent drug combinations within a large candidate space to combat drug resistance. However, existing ML approaches cannot be applied to emerging and understudied pathogens with limited training data. Hence, we developed a computational framework (TACTIC [transfer-learning and cross-species training to infer combination therapies]) to train ML models on data from multiple model bacteria. TACTIC was built using 2,965 drug interactions from 12 bacterial strains and outperformed traditional ML models in predicting drug interaction outcomes for species with limited training data. Upon analyzing \u223c600,000 predicted drug interactions across 18 pathogenic and commensal strains, we identified interactions that are selectively synergistic against Gram-negative and mycobacterial pathogens. We experimentally validated synergistic drug combinations containing clarithromycin, ampicillin, and mecillinam, against clinical strains of M. abscessus, an emerging drug-resistant pathogen. We also confirmed 11 synergistic combinations against Pseudomonas aeruginosa and Staphylococcus aureus strains that cause endophthalmitis.\n\nID: 42413037\nTitle: RIN4 fragments released by AvrRpt2 promote NDR1-dependent activation of RPS2.\nAbstract: Plant nucleotide-binding, leucine-rich-repeat (NLR) immune receptors recognize pathogen effectors and activate immunity. The NLR Resistance to Pseudomonas syringae2 (RPS2) recognizes Avirulence protein interacting with RPS2 (AvrRpt2), a Pseudomonas effector that promotes virulence by proteolytically cleaving a membrane-tethered host protein, RPM1-interacting protein 4 (RIN4). RIN4 cleavage by AvrRpt2 also activates RPS2. A model in which RPS2 is activated by elimination of RIN4 is consistent with the ectopic activity of RPS2 in plants lacking RIN4 but does not explain the link between AvrRpt2's virulence activity and RPS2 activation. We found that non-membrane-tethered RIN4 derivatives are potent cytosolic activators of RPS2. Activation of RPS2 by these RIN4 derivatives, like AvrRpt2-induced activation, and unlike ectopic activation in the absence of RIN4, requires the defense signaling protein NON-RACE-SPECIFIC DISEASE RESISTANCE 1 (NDR1). Cleavage products of RIN4 produced by AvrRpt2 play contrasting roles in the activation of RPS2, with the membrane-tethered C-terminal fragment suppressing RPS2 and the non-membrane-tethered internal fragment, dependent on compatibility with the C-terminal fragment, overcoming its suppression of RPS2.\n\nID: 42412311\nTitle: Using the Damage Response Framework as a Lens to Discuss Acinetobacter baumannii Host-Pathogen Interactions: A Narrative Review and a Call to Action.\nAbstract: The Damage Response Framework (DRF) is a conceptual model that evaluates the outcome of host-pathogen interactions (HPI) by assessing the total damage sustained by the host. The DRF emphasizes that disease results from cumulative host injury arising from the interplay between microbial virulence and the host immune response, rather than from the pathogen alone. HPI has been described as a \"tug of war\" between a pathogen and a host; the DRF improves this analogy by grounding it in reality, as both excessive immune activation and insufficient pathogen clearance can lead to host damage and disease. Acinetobacter baumannii is a Gram-negative pathogen known for its extensive drug resistance and immunomodulatory capacities. The interaction among isolate-specific virulence traits, antimicrobial resistance mechanisms, and host immune status determines the pattern and extent of damage, illustrating central tenets of the DRF. Different A. baumannii isolates may therefore produce varied clinical outcomes across different host conditions, depending on the extent of damage they cause. This narrative review discusses A. baumannii infections from the perspective of the DRF, highlighting how applying the DRF can inform our current understanding of A. baumannii pathogenesis by assessing A. baumannii HPI. We also provide brief insights into how the DRF can inform future research and treatment strategies that integrate host and microbial factors to minimize overall damage and improve host outcomes. A. baumannii infections are difficult to treat and can result in outcomes ranging from asymptomatic colonization to fatal disease. This narrative review examines these differences through the Damage Response Framework (DRF) to improve understanding of A. baumannii infections. The DRF emphasizes that disease results not only from the microbe but also from the interaction between microbial factors and the body\u2019s immune response. When the total damage from the microbe and the immune response exceeds the body's ability to repair, hosts become sick. Hosts with weak immune responses can become very ill because their immune systems cannot control the infection effectively. Conversely, patients with strong immune responses can also become severely ill when their immune systems damage vital tissues and organs in an effort to eliminate the bacteria. This narrative review draws on existing literature to show that different A. baumannii isolates can cause varying levels of illness, depending on the host\u2019s response to the infection. The review also briefly describes the importance of considering antimicrobial therapy as a potential source of host damage and the utility of the DRF in optimizing therapeutic strategies.\n\nID: 42410144\nTitle: Removal and analysis of foodborne-associated pathogens via peptide functionalized nanoparticles.\nAbstract: Foodborne illnesses still remain a major health issue, as the WHO reported 600 million diseases and 420,000 deaths worldwide in 2010. Most of them were caused by pathogens like Campylobacter spp., Salmonella enterica, Escherichia coli, and Listeria monocytogenes. Due to the short shelf life of fresh meat and dairy products, a rapid detection of pathogens in contaminated food products is essential. Since reference methods for microbial food analysis require time-consuming nonselective and selective culturing procedures, the need for more efficient approaches is given. In this study, we employ superparamagnetic iron oxide nanoparticles (SPIONs) functionalized with the peptide KRQGRVEVLYRASWGTV derived from the salivary protein GP-340, to successfully remove different species of food-related microorganisms (Pseudomonas paracarnis, Campylobacter jejuni, Escherichia coli, Enterococcus faecalis, Salmonella enterica, and Listeria monocytogenes) from pure media and homogenates derived from retail meat products. We discovered differences in extraction efficiencies from pure culture ranging from 18% (C. jejuni) to complete extraction (E. faecalis, L. monocytogenes and P. paracarnis) depending on the organism. It was also shown that L. monocytogenes could successfully be removed from co-culture with a high surplus of non-pathogenic P. paracarnis, and also from food matrices. KEY POINTS: \u2022 SPIONCitcan be functionalized with a GP-340 derived peptide (SPIONPep) \u2022 SPIONPep\u00a0can immobilize and remove L. monocytogenes from pure and co-culture with high surplus of non-pathogenic P. paracarnis \u2022 Removal of L. monocytogenes is also possible in complex food matrices.\n\nID: 42409812\nTitle: Allelic variation of an LRR only protein confers dual pathogen resistance in Arabidopsis.\nAbstract: Plants utilize versatile leucine-rich repeat (LRR) proteins to perceive diverse pathogen-derived signals, thereby activating or suppressing defense responses. However, the specific roles of LRR-only proteins in pathogen-specific resistance remain largely unclear. Here, we show that allelic variations in an Arabidopsis thaliana LRR-only gene, LEUCINE-RICH REPEAT IMMUNE PROTEIN 1 (LRIP1), underlies dual functions in combating distinct pathogens. An allele common in arid regions confers resistance to Pseudomonas syringae pv. tomato (Pst) bacteria via salicylic acid (SA) signaling pathway, whereas an allele enriched in high-precipitation regions protects against Botrytis cinerea fungus via camalexin biosynthesis. Divergence in promoter and coding sequences between the two alleles modulates gene expression and elicitor-associated immune responses, thereby promoting pathogen-specific complex formation with BRASSINOSTEROID INSENSITIVE 1 (BRI1)-ASSOCIATED RECEPTOR KINASE 1 (BAK1). Globally distributed A. thaliana accessions carry two distinct LRIP1 allele groups that correlate with local precipitation conditions. These findings demonstrate that a single LRR-only gene can evolve environmentally adapted alleles that optimize immunity against different pathogens in contrasting habitats.\n\nID: 42406835\nTitle: Culture-Based No-Detectable-Growth Assessment And Antioxidant Profiling of Fresh Aloe vera Gel Extract.\nAbstract: Aloe vera (Aloe barbadensis Miller) is widely used in topical and complementary medicine products. However, standardized laboratory workflows for simultaneous evaluation of total antioxidant capacity (TAC), pH behavior, culture-based no-detectable-growth status under defined conditions, and preliminary antimicrobial screening remain limited. Fresh inner-gel Aloe vera extract was prepared aseptically and formulated at 5%, 10%, 15%, and 20% (w/v). pH was measured potentiometrically, and TAC was determined by an automated ABTS radical cation-based colorimetric assay. Culture-based no-detectable-growth assessment was performed by inoculating the extract onto blood agar, eosin methylene blue agar, and Sabouraud dextrose agar, followed by aerobic incubation and visual inspection at 24 h, 48 h, and 72 h. Antimicrobial screening of a 70:30 (v/v) Aloe vera/N-acetyl-L-cysteine test mixture was performed against standard reference strains by disk diffusion and qualitative two-fold tube dilution assays. TAC differed significantly among groups (Kruskal-Wallis, p = 0.014), with the highest values observed in the 20% formulation. No visible bacterial or fungal growth was observed under the tested culture conditions during the 72 h observation period. The Aloe vera/N-acetyl-L-cysteine test mixture produced inhibition zones ranging from 11 mm to 17 mm, with the largest zone observed against Pseudomonas aeruginosa. This workflow provides a practical laboratory approach for preparing and preliminarily characterizing fresh Aloe vera.-based formulations for early-stage complementary medicine research.\n\nID: 42405714\nTitle: Trends in antimicrobial resistance of major gram-negative uropathogens, 2016-2024: A single center retrospective study.\nAbstract: Resistance to empiric antimicrobials has become markedly higher among gram-negative uropathogens in Korea, compared to those in Europe and North America. To guide empiric treatment strategies and to build real evidence, we conducted a retrospective analysis of antimicrobial susceptibility patterns from urine cultures obtained at a university hospital. Antimicrobial susceptibility test (AST) results from initial positive urine cultures (n=11,358, both inpatients and outpatients) collected between 2016 and 2024 were reviewed. The analysis focused on predominant gram-negative isolates-Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Pseudomonas aeruginosa. Resistance rates were determined for twelve commonly used antimicrobials, including third- and fourth-generation cephalosporins, \u03b2-lactam/\u03b2-lactamase inhibitor combinations, carbapenems, aminoglycosides, fluoroquinolones, trimethoprim/sulfamethoxazole, nitrofurantoin, and fosfomycin. Between 2016 and 2024, AST identified E. coli (n=6,533), K. pneumoniae (n=1,348), P. mirabilis (n=677), and P. aeruginosa (n=663). While fluoroquinolone resistance remained persistently high (31.5%-44.5% in E. coli, 6.9%-37.0% in K. pneumoniae), its annual trend showed to be stable. Cefepime resistance increased steadily in most gram-negative isolates (annual percentage change [APC]=16.1%-25.0%). Although Carbapenem resistance remained low but it increased steadily in E. coli and K. pneumoniae (APC=22.2%). Nitrofurantoin and fosfomycin retained strong activity against E. coli, though their efficacy varied among other pathogens. This 9-year longitudinal study reveals sharp cefepime resistance increases post-2019 and persistently high fluoroquinolone resistance among major four gram-negative uropathogens. Targeted antimicrobial stewardship are essential to optimize urinary tract infection management and reduce unnecessary broad spectrum antimicrobials in Korea.\n\nID: 42405072\nTitle: Citrus sinensis zest-mediated silver nanoparticles for rapid dye removal and antimicrobial properties.\nAbstract: Growing interest in sustainable and renewable nanotechnology has accelerated the development of green synthesis strategies that are both environmentally friendly and economically viable. In this study, we report a simple, low-cost, and eco-conscious approach for synthesizing silver nanoparticles (AgNPs) using an aqueous zest extract of Citrus sinensis (Cs), which naturally serves as both the reducing and stabilizing agent. The phytochemicals present in the extract-including ascorbic acid, phenolic acids, flavonoids, terpenoids, and polysaccharides-effectively reduce Ag+ ions to stable AgNPs. The formation of AgNPs was confirmed through UV-Vis spectroscopy, revealing a characteristic surface plasmon resonance peak at 420 nm. FESEM imaging demonstrated predominantly spherical nanoparticles with uniform crystallite morphology and rough surface features, while TEM analysis showed an average particle size of approximately 15 \u00b1 5.3 nm. XRD patterns confirmed the polycrystalline nature of the particles with diverse d-spacings, and EDX analysis indicated high purity (93.91% Ag) of the synthesized material. Compared to previously reported green synthesized nanoparticle systems, the biosynthesized AgNPs displayed excellent catalytic activity, achieving dye removal efficiencies of 98.93% (within 18 min) for methyl orange (MO) and 92.15% (within 30 min) for methylene blue (MB) under mild conditions, highlighting the advantage of waste-derived plant extract-mediated synthesis. Moreover, they exhibited strong antibacterial activity, showing notable inhibition against Gram-negative bacteria (E. coli,Pseudomonas spp.,K. pneumoniae, andSalmonella spp.) compared with Gram-positive strains (S. aureus andB. cereus), as assessed by inhibition zone measurements.\n\nID: 42404779\nTitle: Childhood sepsis burden: pathogens/antimicrobial-resistant bacteria, 1990-2021 and 2050 forecasts.\nAbstract: To assess the global burden and trends of childhood sepsis, and to evaluate whether clarifying these aspects can provide a basis for formulating targeted prevention and treatment strategies for the condition. Using the Global Burden of Disease (GBD) 2021 database, we analyzed sepsis in 0-14-year-olds, covering 62 pathogens (21 drug-resistant), 84 \"pathogen-drug\" combinations, 12 infection syndromes, and indicators (deaths, disability-adjusted life years [DALYs], age-standardized rates). Antimicrobial resistance (AMR) was defined by two counterfactual scenarios; an autoregressive integrated moving average (ARIMA) model forecast AMR-related sepsis to 2050. From 1990 to 2021, global sepsis-related deaths among children declined from 6.43 million to 2.24 million, and DALYs dropped from 578 million to 203 million. The estimated annual percentage change (EAPC) in age-standardized mortality rate (ASMR) and DALY rate (ASDR) was -3.35 and -3.33, respectively. AMR-related sepsis burden also decreased, with notable declines in both AMR-associated and AMR-attributable deaths and DALYs. In 2021, the highest burden remained in Sub-Saharan Africa, while the lowest was in High-income regions. Leading pathogens causing child sepsis deaths included Streptococcus pneumoniae, Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa. Bloodstream infections, lower respiratory infections, and diarrhea were the most common infection syndromes leading to sepsis-related deaths. Global childhood sepsis burden dropped, but high-burden regions (e.g., Sub-Saharan Africa, South Asia) need focus. Future efforts should optimize healthcare, strengthen AMR control, promote vaccination, and improve sanitation.\n\nID: 42402928\nTitle: Assessment of the enhanced antibacterial activity of snail mucus, thymol, and ferulic acid in a rat model of burn wounds infected with Staphylococcus aureus and Pseudomonas aeruginosa.\nAbstract: To develop and evaluate a novel topical formulation - comprising snail mucus, thymol, and ferulic acid (STF) - for treating wounds infected with multidrug-resistant bacteria, and to compare its therapeutic efficacy against silver sulfadiazine. The in vitro antimicrobial properties of STF were analyzed using checkerboard assays to determine the fractional inhibitory concentration (FIC) index. The cytotoxicity of STF was determined using the MTT viability assay using L929 fibroblasts. The in vivo efficacy of STF was assessed using a rat excisional wound model, and wound closure rates were measured at 14\u2009days post-infection. STF showed an additive interaction in the in vitro model (FIC index: 0.717-0.936) and possessed low cytotoxicity (IC50: 705.4\u2009\u00b5g/mL) compared to the individual compounds. In the in vivo model, the group treated with STF showed significantly faster wound healing and decreased inflammation compared to all other groups, including the silver sulfadiazine group. The combination of snail mucus in STF is a highly effective remedy for infected wounds, providing complementary benefits in vivo by coupling antimicrobial activity with pro-regenerative functions, and demonstrates superiority over silver sulfadiazine.\n\nID: 42422745\nTitle: Diverse banana endophytes reveal potential genotype-driven community structure affected by domestication.\nAbstract: Plant endophytic microbiomes play critical roles in plant health, productivity, and stress tolerance, however, their relationship with host genotype remains poorly understood. This study focused on endophytic microbiomes of six banana (Musa spp.) cultivars grown under shared environmental conditions to determine how genotype influences microbial diversity and structure. We used deep amplicon sequencing to investigate the endophytic microbiomes from above- and below-ground tissues of wild diploid cultivars Musa balbisiana, M. balbisiana \"Thai Black\", and M. textilis, and domesticated triploid cultivars Dwarf Cavendish, Williams Hybrid, and hybrid FHIA-25, grown in sympatry. Across all samples, dominant genera included Pseudomonas, Acinetobacter, Enterobacter, Devosia, and Rhizobium, while 27.4% of ASVs were unclassified. Although many core taxa were shared, each cultivar and tissue harbored distinct low-abundance microbial taxa. Beta diversity analyses revealed that banana cultivar explained a small but significant proportion of community variation (Bray-Curtis R 2\u202f=\u202f2.7%, p\u202f=\u202f0.002; Weighted UniFrac R 2\u202f=\u202f2.9%, p\u202f=\u202f0.005), whereas tissue type and domestication contributed less to overall variation. PICRUSt2 predicted functional differences among endophytic communities across banana cultivars, with 49 pathways differing between wild and domesticated plants, including enrichment of lipid metabolism, biotin biosynthesis, and aromatic compound degradation in domesticated cultivars. However, because domestication status and ploidy differed among the selected cultivars, these effects could not be fully separated in the current study. Together, these results indicate that banana genotype influences endophytic microbiome composition and predicted function, although host genotype accounted for only a modest proportion of the observed variation, highlighting the importance of additional ecological and environmental factors in shaping plant-associated microbial communities.\n\nID: 42421768\nTitle: Compartment-Specific Variation in Bacterial Microbiome and Polyphyllin Profiles in Paris polyphylla.\nAbstract: Paris polyphylla (P. polyphylla) is a valuable traditional Chinese medicinal plant, yet the spatial distribution of its compartment-specific bacterial microbiomes and their correlative relationships with bioactive polyphyllins remain poorly characterized. Here, we combined 16S rRNA amplicon sequencing, metabolite analysis, and bioinformatics to investigate the distribution patterns of bacterial communities and polyphyllins across bulk soil (BS), rhizosphere soil (RS), root endospheres (REs), stem endospheres (SEs), and leaf endospheres (LEs) of P. polyphylla. A spot inoculation assay was further used to verify the interactions between the dominant genus Pseudomonas (strain Pseudomonas palleroniana P6) and key polyphyllin I and VII. The results showed that polyphyllin I and II were highly accumulated in aerial SEs and leaves, whereas polyphyllin VI, VII, and diosgenin were predominantly concentrated in REs. Bacterial diversity and richness showed a gradual decline from BS to LE, with ecological niche differentiation identified as the primary driver of bacterial community divergence across compartments, which was further modulated by polyphyllin content. Pseudomonas, the dominant genus in all compartments, displayed a decreasing relative abundance with ascending compartmental niches, and its abundance was significantly negatively correlated with polyphyllin I levels but positively correlated with polyphyllin VII levels-a trend experimentally validated by gradient polyphyllin concentration-based microbial growth assays. Redundancy analysis (RDA) indicated that polyphyllin content (especially VI, VII, and diosgenin) significantly influenced bacterial community composition. Additionally, P. polyphylla exhibited selective enrichment of beneficial microbes, with selection pressure intensifying progressively across compartments. This study clarifies the compartment-specific distribution patterns of bacterial microbiomes and polyphyllins in P. polyphylla and their correlative relationships, deepens the understanding of plant-microbiome interactions in medicinal plants, and provides a theoretical basis for optimizing P. polyphylla cultivation strategies and developing microbial inoculants for sustainable agricultural production.\n\nID: 42420316\nTitle: A portable Cas6f-based system for multiplex translational repression in bacteria.\nAbstract: Engineered small RNAs (sRNAs) enable programmable gene knockdowns and support metabolic engineering and multiplex regulation in model bacteria. Still, precise, tunable, and multiplex gene repression remains a challenge in synthetic biology. Common tools can impose genetic burden, depend on host RNA factors, or do not transfer well across species. Here we present MORTISE (Multiplex, ORthogonal Translation Interference SystEm), a compact Cas6f-based platform for programmable translational repression in Gram-negative bacteria. The system functions without host Hfq or RNases and operates robustly in Escherichia coli and Pseudomonas putida. We demonstrate repression in both species using chromosomal reporter assays, with performance improving when guide and target transcription are matched and when the translation initiation region is targeted. Single-promoter multiplexing enables simultaneous knockdowns and a cloning toolbox facilitates assembly of up to nine guides in a single step. Finally, MORTISE is leveraged to boost malonyl-coenzyme A-dependent production in P. putida, supporting pathway balancing.\n\nID: 42419299\nTitle: Structures of the Xcp and Hxc T2SS endopili provide new insights into type IV pili subfamilies.\nAbstract: Type IV filaments (T4F) are widespread bacterial appendages involved in adhesion, motility, DNA uptake, and protein secretion. In the type II secretion system (T2SS), a short pilus-like structure termed the endopilus drives protein export across the outer membrane. Despite its important function, the specific molecular determinants of endopili remain poorly understood. Here, we used cryo-electron microscopy to determine the structures of two endopili assembled by the independent Hxc and Xcp T2SS systems of Pseudomonas aeruginosa. Comparative analyses reveal defining structural and chemical features of T2SS endopili, including a unique surface property of the XcpG endopilus that explains its distinctive bundling behavior. Mapping inter-subunit interactions further identifies residues governing selective assembly within coexisting secretion systems. Comparisons with related type IVa pili define a conserved architectural framework and constrained helical parameters characteristic of the T2SS endopilus family, providing insight into how subtle chemical variations encode functional specificity and efficient protein export.\n\nID: 42419029\nTitle: Metagenomic investigation of VIM-type metallo-\u03b2-lactamase-producing multidrug-resistant Pseudomonas aeruginosa associated with a hospital outbreak across multiple hospital units in Saudi Arabia.\nAbstract: Healthcare-associated infections (HAIs) caused by multidrug-resistant (MDR) Pseudomonas aeruginosa (P. aeruginosa) represent a public health challenge, particularly when associated with VIM-type metallo-\u03b2-lactamases (MBLs), which limit therapeutic options. Conventional microbiological methods may underestimate resistance determinants and transmission dynamics. Long-read metagenomic sequencing is a promising approach for Pathogen detection, resistome characterization, and genomic surveillance. The study's objectives were to characterize the resistome, including detection of the blaVIM gene, assess genomic relatedness and potential transmission dynamics, and evaluate the diagnostic value of metagenomics compared with conventional microbiological approaches. This retrospective infection control investigation included seven hospitalized patients from multiple hospital units. Clinical specimens included blood, respiratory specimens, surgical tissue, and device-associated material. Conventional microbiological investigations included bacterial culture, identification, and antimicrobial susceptibility testing (AST) using the VITEK 2 automated system. Carbapenemase genes were detected using Xpert Carba-R. Long-read metagenomic sequencing was conducted using Oxford Nanopore Technologies (ONT) on the GridION platform. Bioinformatic analysis was performed using the CosmosID platform for taxonomic profiling, antimicrobial resistance gene detection, and genomic relatedness assessment. Conventional microbiological methods identified carbapenem-resistant Pseudomonas aeruginosa (CRPA) in five cases, whereas ONT sequencing detected the blaVIM gene in all seven samples, demonstrating superior diagnostic sensitivity. A highly conserved resistome profile was identified across all investigated cases, including multiple \u03b2-lactamase and aminoglycoside, fluoroquinolone, and polymyxin-associated resistance determinants. Genomic relatedness analysis demonstrated close clustering patterns with minimal genomic variability, suggesting possible circulation of closely related MDR strains. These findings highlight the added value of ONT sequencing in identifying concealed resistance determinants and improving transmission tracking compared with conventional diagnostic approaches. Future investigations involving larger sample sizes and environmental surveillance are needed to further clarify transmission dynamics and potential reservoirs of VIM-producing P. aeruginosa.\n\nID: 42417706\nTitle: Germination and Polishing Reshape Microbial Communities in Japonica and Indica Rice.\nAbstract: Germination is a process used to improve the nutritional quality of rice. However, its impact on rice microbiomes remains poorly understood. This study evaluated the microbiota of two rice ecotypes, low-amylose (Mochi) and high-amylose (BRS Formoso), after germination and polishing using 16S rRNA and ITS amplicon sequencing. Bacterial alpha diversity was highest in commercial brown rice (Shannon index 3.21) and lowest in commercial polished rice (1.50). Beta diversity indicated that germination exerted a similar effect on bacterial community composition in both ecotypes. Principal Coordinate Analysis suggested that polishing did not markedly influence microbiome composition relative to germination. The microbial profiles of Mochi and BRS Formoso were dominated by Pantoea, Pseudomonas, Rhizopus, and Moesziomyces. Overall, germination strongly influenced bacterial and fungal communities, emerging as the main factor shaping microbial structure and dynamics. These findings provide new insights into how processing affects the rice microbiome, with implications for food quality and safety.\n\nID: 42413747\nTitle: Mechanism of injury influences early microbial trajectories and infection pathways in open fractures: A 16S rDNA study.\nAbstract: The mechanism of injury in open fractures-whether blunt or sharp- may significantly impact early microbial colonization and how those microbial communities develop in relation to wound microbiota, which leads to fracture-related infection (FRI). Nevertheless, the influence of trauma biomechanics on infection development and microbial community dynamics is poorly studied. This study aimed to assess how different injury mechanisms influence wound microbiota dynamics and susceptibility to FRI. In this prospective cohort study, we recruited 155 patients with Gustilo-Anderson type II, IIIA, or IIIB open fractures. Deep tissue samples were obtained from all patients during their initial surgical debridement. In a subset of 28 patients who developed FRI, a second sample was collected at the time of re-debridement. The samples were matched and stratified into four groups based on trauma mechanism and infection status: Pre-debridement sharp, Pre-debridement blunt, Infection sharp, and Infection blunt. Microbial profiling was conducted using 16S rDNA sequencing. The sample metadata was analyzed in QIIME2, from which diversity indices (alpha and beta) were computed. The taxonomic composition and abundance were assessed at the genus level, while patterned relationships between groups were visualized through heatmap clustering. Beta diversity analysis showed that Pre-debridement sharp group clustered closely with both infection groups, significantly diverging from the Pre-debridement blunt group (p\u202f<\u202f0.001). In terms of alpha diversity, the Pre-debridement sharp group exhibited the highest levels across richness, evenness (p\u202f<\u202f0.05), as well as phylogenetic breadth. Taxonomic profiling showed that sharp trauma wounds were initially enriched with potentially pathogenic genera such as Pseudomonas, Acinetobacter and Staphylococcus, while blunt trauma wounds were dominated by low virulence taxa, like Bacillus. Heatmap analysis confirmed that the microbial composition of sharp samples was similar to those from both infection groups, suggesting that sharp trauma wounds possess a diverse microbial community that resemble the architecture seen in FRI. While the overall infection rate did not differ between blunt and sharp trauma, the mechanism of injury significantly influenced early microbial colonization patterns and infection development pathways. These findings emphasize the importance of trauma-specific microbiota profiling in understanding and potentially guiding the prevention of FRI.\n\nID: 42413479\nTitle: In\u00a0Vitro Efficacy of Quinolones and Carbapenems against Nonfermenting Gram-Negative Bacteria Isolated from Clinical Specimens in a Nepalese Tertiary Care Hospital.\nAbstract: Nonfermenting Gram-negative bacteria (NFGNB) pose a significant public health threat due to multidrug resistance (MDR) mediated by biofilms, efflux pumps, and carbapenemases. This cross-sectional study evaluated the minimum inhibitory concentrations (MICs) of quinolones and carbapenems against the Acinetobacter calcoaceticus-baumannii (ACB) complex and Pseudomonas aeruginosa isolated from clinical specimens at the Nepal Armed Police Force Hospital, Balambu, Kathmandu, Nepal. These NFGNB were isolated and identified using standard microbiological methods. Quinolone- and carbapenem-resistant isolates, screened by disc diffusion, were tested for MICs of quinolones and carbapenems using broth microdilution. Statistical analyses were performed in SPSS v. 17.0. Ninety-two NFGNB were isolated, predominantly from urine (40.2%; 37/92). The MDR proportion was high in P. aeruginosa (85.7% [18/21] versus 80.28% [57/71]). The extensively drug-resistant (XDR) proportion was high in the ACB complex (14.1% [10/71] versus 4.8% [1/21]). The MIC50 in P. aeruginosa against norfloxacin and ofloxacin was \u22658 and \u22650.5 \u00b5g/mL, respectively. The MIC50 against ciprofloxacin in P. aeruginosa was \u22658 \u00b5g/mL, whereas it was \u226532 \u00b5g/mL in the ACB complex. MIC50 against levofloxacin was \u22650.5 \u00b5g/mL in P. aeruginosa, unlike the ACB complex (\u226516 \u00b5g/mL). The MIC50 for meropenem was lower in the ACB complex (\u22654 versus \u22658 \u00b5g/mL) than in P. aeruginosa, whereas both showed similar MIC90 (\u226564 \u00b5g/mL). ACB complex showed higher MIC50 against imipenem (\u22654 \u00b5g/mL) than P. aeruginosa (\u22650.125 \u00b5g/mL). Over three-fourths of the NFGNB infections were caused by the ACB complex, exhibiting high XDR rates and elevated MICs to quinolones and carbapenems, underscoring the need for strengthened antimicrobial stewardship.\n\nID: 42410687\nTitle: Endophytic Microbiome Diversity in Citrus Leaves and the Biocontrol Potential Bacteria against Xanthomonas citri subsp. citri.\nAbstract: Citrus is a pivotal economic crop in southern China, while citrus canker caused by Xanthomonas citri subsp. citri (Xcc) is a devastating quarantine disease that severely threatens the sustainability of the citrus industry. Endophytic bacteria represent a promising sustainable alternative for disease management, yet systematic exploration of their potential against Xcc in citrus leaves remains limited. To address this, we characterized the leaf endophytic microbiome from major citrus-growing regions in southern China via high-throughput sequencing, revealing significant differences in the endophytic bacterial community structure between symptomatic and asymptomatic citrus leaves, with a significantly elevated relative abundance of Proteobacteria and prominent enrichment of the genera Xanthomonas, Enterobacter, and Pseudomonas in symptomatic tissues. Furthermore, symptomatic leaves harbored significantly higher endophytic bacterial diversity than asymptomatic leaves from the same production region, and the Xanthomonas abundance in the samples was highly consistent with the actual field disease severity. From 519 bacterial isolates, four strains-A1 (Bacillus altitudinis), A3 (Bacillus velezensis), A6 (Pseudomonas parafulva), and A7 (Delftia tsuruhatensis) demonstrated strong in vitro and detached-leaf antagonism against Xcc. Strain-specific fermentation parameters were optimized, and all four strains were successfully formulated into wettable powders. In a field trial, these formulations achieved control efficacies ranging from 25.8% to 53.5%, with strain A1 showing the highest and most sustained activity. Strains A3, A6, and A7 also exhibited broad-spectrum antibacterial activity against several other phytopathogenic bacteria. This study not only elucidates shifts in the endophytic microbiome associated with citrus canker but also provides novel, efficacious biocontrol resources and a practical development pipeline for sustainable disease management.\n\nID: 42406180\nTitle: Next-generation biodegradation of chlorpyrifos: integrative microbial strategies, molecular mechanisms, and environmental impacts.\nAbstract: Chlorpyrifos (CP) belongs to organophosphate pesticide group. It is extensively applied in agricultural and household settings due to its broad-spectrum insecticidal properties. However, its persistence, bioaccumulative behavior, and toxicological effects on non-target organisms, including humans, pose significant environmental and public health concerns. CP and its metabolites, particularly two including 3,5,6-trichloropyridinol (TCP) and chlorpyrifos-oxon (CPO), have been recently reported to be widely found various samples such as in soils, sediments, water bodies, crops, and even human biological fluids. These compounds disrupt biogeochemical cycles, alter soil microbial communities, inhibit enzyme activities, and are linked to neurotoxicity, endocrine disruption, and genotoxic effects. Conventional remediation strategies such as photodegradation, ultrasonication, and filtration remain ineffective due to incomplete degradation and secondary pollution risks. Recent studies highlight the efficiency of microbial degradation, especially by bacteria such as Bacillus, Klebsiella, Pseudomonas and Enterobacter as a promising, eco-friendly alternative. These microorganisms utilize CP as a only carbon source, and degradation calibre is greatly governed by various abiotic factors like pH, temperature, and moisture. The genetic as well as enzymatic analyses reveal key roles of organophosphorus hydrolases encoded by genes such as opd and mpd. The integration of plant growth-promoting traits and laccase activity further enhances their bioremediation capability. Additionally, recent advancements in biosensing techniques for CP detection offer improved sensitivity and real-time monitoring. This review provides a comprehensive analysis of CP's environmental fate, toxicological impact, degradation pathways, and the emerging role of bacterial bioremediation, highlighting its potential for sustainable environmental detoxification.\n\nID: 42405543\nTitle: Metagenomic Analysis of Thoracic Empyema Etiology Through Next-Generation Sequencing Enhances Conventional Culture Techniques.\nAbstract: This study aimed to analyze the microbiome of thoracic empyema using metagenomic methods and compare the results with conventional culture methods to increase diagnostic accuracy and enhance antibiotic therapy. This study involved 30 patients with thoracic empyema from hospitals in Riau Province, Indonesia. Pleural fluid samples were collected for culture analysis and identification using the Vitek 2 compact system and metagenomic analysis. Patient clinical data were also collected. Culture methods showed a 40.0% positive rate, with Gram-negative bacteria (Klebsiella pneumoniae and Pseudomonas aeruginosa) predominating. Metagenomics showed a 56.7% positive rate, identifying a more diverse microbiome, including fungi (29.4% abundance), other Gram-negative bacteria (26.5%), and anaerobic bacteria (22.5%). Comparison of the two methods showed 36.7% complete agreement and 23.3% partial agreement, with 40% disagreement, with a Kappa coefficient of 0.416 and P-value of 0.016 (P<0.050). Metagenomic NGS offers significant advantages in detecting the microbiome of thoracic empyema, particularly fungi and anaerobic bacteria, which are often missed by conventional culture methods. This has the potential to improve diagnostic accuracy and optimize antibiotic therapy. Further research with larger sample sizes is needed.\n\nID: 42405256\nTitle: Dietary prebiotics and synbiotics modulate gut microbiota and improve growth performance of Mexican pike silverside Chirostoma estor.\nAbstract: Aquaculture is the fastest-growing food production sector worldwide and is vital for a sustainable animal protein supply. However, optimizing fish performance in captivity remains a major challenge, requiring functional diets that support a healthy holobiont. This study evaluated the effects of balanced experimental diets supplemented with inulin or yeast cell wall (prebiotics), Lactobacillus acidophilus (probiotic), or their combination (synbiotics) on juvenile pike silverside (Chirostoma estor). Growth performance was monitored, and gut microbiota composition was characterized by 16S rRNA gene metabarcoding. Synbiotic and yeast cell wall supplementation significantly improved growth parameters, including weight gain, final body weight, and specific growth rate, compared to the control. Microbiota profiling revealed a core community of nine genera (Bacillus, Citrobacter, Cutibacterium, Lactobacillus, Pseudomonas, Spiroplasma, Stenotrophomonas, Streptococcus, and Thermogemmatispora), with each treatment inducing distinct shifts in bacterial composition. Candidate probiotic taxa, including Lactobacillus spp., were also identified as part of the gut microbial response to dietary treatments. Functional predictions further indicated an enrichment of bacterial biosynthetic pathways in synbiotic and yeast cell wall treatments, aligning with the observed improvements in growth and feed efficiency. These findings indicated that yeast cell wall and synbiotic supplementation modulated gut microbial composition and were associated with improved growth performance in C.\u00a0 estor, underscoring the role of microbiome-targeted nutrition in this species.\n\nID: 42405165\nTitle: Directed evolution of a cytochrome P450 monooxygenase for improved perillyl alcohol biosynthesis via a tailored genetically encoded biosensor.\nAbstract: Perillyl alcohol is a naturally occurring terpene with promising anticancer properties. However, like other oxidized terpenes, its limited biosynthetic availability hinders its development as a therapeutic lead. Cytochrome P450 monooxygenase CYP153A6 catalyzes the key hydroxylation of limonene to yield perillyl alcohol in Escherichia coli, yet the enzyme is the rate-limiting step in this pathway and has not previously been improved by directed evolution. Here, we report the development of a genetically encoded biosensor based on the cymene repressor CymR from Pseudomonas putida F1, engineered to selectively detect perillyl alcohol over its non-hydroxylated precursor limonene, and its application to the directed evolution of CYP153A6. A single substitution (S77L) in the CymR effector-binding pocket dramatically increased biosensor sensitivity and dynamic range toward perillyl alcohol while maintaining discrimination against limonene. The tailored CymR-S77L biosensor was coupled to a CYP153A6 random mutant library to enable high-throughput fluorescence-based screening of variants. Ultimately, seven CYP153A6 variants, some with multiple mutations, were identified to have improved perillyl alcohol titers. Deconvolution of beneficial mutations revealed that a single substitution, A287T, located near the predicted CYP153A6:ferredoxin reductase interface, was sufficient to increase perillyl alcohol productivity 4.2-fold relative to wild-type without compromising regio- or chemoselectivity. These results demonstrate that biosensor-guided directed evolution is an effective and selective strategy for engineering P450-dependent terpene hydroxylation pathways and establish a generalizable platform for developing monoterpene-responsive biosensors and applying them to the directed evolution of terpene-modifying enzymes.\n\nID: 42404574\nTitle: The role of dupilumab in skin microbiome shifts in the Netherton genodermatosis: a case report and review of literature.\nAbstract: Skin dysbiosis plays a crucial role in inflammatory skin diseases, particularly in genodermatoses such as Netherton syndrome (NS). This case report aimed to investigate changes in the skin microbiome of a patient with Netherton syndrome before and during dupilumab therapy, with the goal of expanding the limited evidence currently available on this topic. We report the case of a 35-year-old woman diagnosed with NS at birth, who, prior to dupilumab therapy, presented with atopic dermatitis (AD), ichthyosis linearis circumflexa, and severe pruritus. Dupilumab therapy was initiated, and skin swabs were collected from lesional sites at three different time points: at baseline, after 1\u202fmonth, and after 1\u202fyear of continuous dupilumab therapy. At baseline, a microbiome analysis revealed low microbial diversity with a predominance of Pantoea and Pseudomonas species. After 1\u202fyear, a significant increase in microbial diversity, with a predominance of Staphylococcus species and an increase in Malassezia species, was observed. Clinically, the patient experienced remission in parallel with these microbiome shifts. Post-treatment, the skin microbiome showed increased microbial diversity and re-establishment of beneficial commensals, more closely resembling healthy skin. The findings of this case report underscore the role of dupilumab in restoring a healthy skin microbiome along with symptomatological and clinical improvement in the genodermatosis Netherton syndrome.\n\nID: 42402284\nTitle: Integrated metagenomic and metaproteomic insights into current-carrying-coil magnetic field enhanced synergistic methanogenic system and antibiotic resistance gene reduction in cow manure anaerobic digestion.\nAbstract: Anaerobic digestion (AD) is a sustainable strategy for valorizing cow manure (CM). However, the high ammonia (NH3) concentration and low biodegradability of CM limit hydrolysis and methane production. This study investigated the application of a current-carrying-coil-based magnetic field (CCC-MF) to AD of CM. The CCC-MF digesters showed higher soluble chemical oxygen demand and attained 16.59\u00a0% higher ammonium nitrogen reduction, contributing to a 37.50\u00a0% higher average methane yield than the control. Further, CCC-MF digesters showed higher enzyme activities (alkaline protease\u00a0+\u00a030\u00a0%, acetate kinase\u00a0+\u00a022\u00a0% and hydrazine dehydrogenase\u00a0+\u00a026\u00a0%) and increased microbial metabolic indices (dehydrogenase activity\u00a0+\u00a017\u00a0% and electron transport system activity\u00a0+\u00a010\u00a0%) than the control. Metagenomics analysis revealed that abundances of the bacterial genera Mesotoga, Aminobacterium, Xiashengella, unclassified Candidatus Cloacimonadota, Advenella, Pseudomonas, and Comamonas increased, whereas the acetoclastic methanogen Methanothrix decreased by 2.58\u00a0%, accompanied by 2.07- and 1.64-fold increases in hydrogenotrophic methanogens Methanospirillum and Methanobacterium, respectively, in CCC-MF digesters. The abundance of nitrogen dissimilation and assimilation genes NirK, NorB, NarB, NapA, nmo, and GLT1 were enhanced by 1.14, 1.04, 2.30, 1.32, 1.17, and 1.29-fold in CCC-MF digesters compared to the control. Moreover, metaproteomics revealed higher up-regulated differentially expressed proteins in NH3 reduction-related amino acid metabolism pathways in CCC-MF digester compared to control. Additionally, reduced abundances of bacitracin, polymyxin, sulfonamide, and multidrug antibiotic resistance (MAR) gene types were observed in the CCC-MF digesters. The findings suggest that applying CCC-MF may be associated with higher methane production and ammonium reduction, potentially linked to a more favorable synergistic methanogenic system and nitrogen transformation pathways.\n\nID: 42402172\nTitle: Characterization and Therapeutic Potential of a Novel Lytic Phage-Derived Endolysin PA16cLys Against Uropathogenic Pseudomonas aeruginosa Biofilms.\nAbstract: Pseudomonas aeruginosa (P. aeruginosa) is a leading cause of urinary tract infections (UTIs). The escalating misuse of antibiotics has led to the emergence of multidrug-resistant strains, necessitating novel therapeutic approaches. Bacteriophages and their encoded lytic enzymes offer unique advantages for antimicrobial therapy and show promising potential for future applications. This study focuses on the characterization of uropathogenic P. aeruginosa phages and their lytic enzymes, investigating their biological properties and potential therapeutic applications. We isolated a novel lytic bacteriophage, vB_PaeS_PA16c (PPA16c), which demonstrated favorable biological characteristics, including a 34% biofilm eradication capacity within 6\u2009h. The phage-encoded endolysin PA16cLys exhibited superior antibacterial efficacy compared to the phage itself. Notably, it achieved significant biofilm reduction (~63%) after 1\u2009h treatment without requiring outer membrane permeabilizers. This endolysin exhibited enhanced antibacterial efficacy in eradicating mature P. aeruginosa biofilms. Regarding host range, PA16cLys displayed broader lytic activity. Both the phage and endolysin demonstrated cross-order lytic activity against other pathogenic bacteria. Crucially, PA16cLys maintained potent inhibitory activity against phage-resistant mutants. These findings provide a theoretical foundation for utilizing phages and lytic enzymes against uropathogenic P. aeruginosa and establish a research basis for developing novel antimicrobial therapy.\n\nID: 42401803\nTitle: A genome-wide association study to identify the genetic loci underlying carbapenem resistance in Acinetobacter baumannii.\nAbstract: Carbapenem-resistant Acinetobacter baumannii (CRAB) presents a significant public health concern, and is recognized as a key contributor to the global antimicrobial resistance (AMR) crisis. This study applied a bacterial genome-wide association study (bGWAS) framework to identify genetic factors beyond the canonical carbapenemase OXA-23, that may contribute to carbapenem resistance. A. baumannii isolates with publicly available whole-genome sequencing (WGS) data and carbapenem-specific antimicrobial susceptibility testing (AST) results were compiled (n\u2009=\u20091,601). Unitigs were extracted from de novo assemblies, and single-nucleotide polymorphisms (SNPs) were called from raw sequence reads mapped to seven selected reference genomes. The unitig- and SNP-based genome-wide association analyses were carried out, including conditional analyses based on the known resistance determinants. Structural analysis was performed for the select candidate mutations. The population was highly clonal and comprised ten lineages, including three predominantly resistant lineages (ST1, ST2, and ST32). Known CRAB-associated loci, including OXA-23, the RND efflux pump regulator AdeL, and OXA-66 variants (Ile129Leu and Leu167Val), were readily identified. Structural analysis of mutations identified outer-membrane proteins as potential candidate loci, however these loci were not supported in the conditional analyses across all reference genomes. The candidate loci supported in the conditional analysis across reference genomes included an amino acid substitution in a LysR-type regulator adjacent to the biofilm-associated operon pgaABCD, and an intergenic substitution located between enzymes involved in LPS remodeling. OXA-23 is the major determinant of carbapenem resistance in A. baumannii. Additional resistance mechanisms may become significant in the absence of OXA-23, including efflux pump regulation (AdeL), membrane permeability (OprD, DcaP), lipopolysaccharide (LPS) transport (PqiB), LPS remodeling (acyltransferase, glycosyltransferase), and biofilm formation (LysR). Integration of the conditional analysis based on known resistance determinants and a multi-reference mapping framework may improve the detection and prioritization of candidate associations.\n\nID: 42401059\nTitle: The overlooked risk of horizontal transfer of plasmid-borne antibiotic resistance genes induced by organophosphate esters in aquaculture environments.\nAbstract: In recent years, the emergence of new environmental pollutants has drawn increasing attention to the plasmid-mediated conjugation transfer of antibiotic resistance genes (ARGs) induced by these contaminants. The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized.\n\nID: 42401050\nTitle: Dual role of HCN produced by the endophyte Pseudomonas urmiensis A32 in biocontrol and the defence response of pepper.\nAbstract: Plant-associated Pseudomonas species are widely recognised for their ecological versatility and potential as sustainable biocontrol and plant growth-promoting agents. Among their diverse metabolites, hydrogen cyanide (HCN) is traditionally considered a potent antimicrobial compound, yet its broader role in plant-microbe interactions remains underexplored. This study investigated Pseudomonas urmiensis A32, an endophytic bacterium previously shown to enhance drought tolerance and disease resistance in pepper (Capsicum annuum). Whole-genome analysis revealed genes involved in nutrient acquisition, stress protection, and competitive exclusion, including secondary metabolite clusters for carotenoid and HCN biosynthesis. Wild-type A32 showed increased tolerance to oxidative stress, highlighting a redox-active role for HCN. Seed inoculation with A32 reduced disease symptoms and pathogen load in pepper plants challenged with Xanthomonas euvesicatoria, indicating that HCN contributes not only to direct pathogen antagonism but also to modulation of host immune responses. Biochemical analyses showed decreased activity of antioxidant enzymes and increased phenylalanine ammonia-lyase activity. Gene expression analyses revealed upregulation of PR1 and the antimicrobial peptide gene DEF1, indicating enhanced activation of defence genes. These findings demonstrate that HCN acts as a multifunctional metabolite that fine-tunes the balance between reactive oxygen species detoxification and signalling, and integrates microbial biocontrol with host immune priming. In summary, this work highlights the ecological adaptability of P. urmiensis A32 and its potential as an effective bioinoculant for sustainable crop protection.\n\nID: 42400848\nTitle: Tracking Synthetic Adhesins on Bacterial Surfaces with Immunofluorescence Microscopy.\nAbstract: Programmable bacterial adhesion enables applications in biocatalysis, living materials, and targeted drug delivery. This functionality can be achieved through the expression of synthetic adhesins in bacterial cells. These molecules are hybrid proteins composed of four key elements: (i) a signal peptide for secretion; (ii) the beta barrel domain of an autotransporter for surface display; (iii) a nanobody module providing specific recognition and targeting capabilities; and (iv) an epitope tag for expression tracking and localization. This chapter describes a detailed protocol for visualizing these synthetic adhesins on Escherichia coli and Pseudomonas putida using indirect immunofluorescence combined with Super-Resolution Microscopy (SRM) techniques, such as STimulated Emission Depletion (STED). The workflow includes plasmid introduction into the bacterial cells, induction, immunostaining, and image acquisition to spatially track the adhesins on the cell surface.\n\nID: 42400379\nTitle: Plant-Plant Communication for Systemic Acquired Resistance under Biotic Stress Spatiotemporally Tracked by an In Situ Surface-Enhanced Raman Spectroscopy Aerosol Spraying Analyzer.\nAbstract: This study pioneers a surface-enhanced Raman spectroscopy (SERS) analyzer leveraging engineered Au core/Ag shell nanocubes (Au@AgNCs) to bridge in planta pathogen tracking with airborne defense signal monitoring, enabling unprecedented decoding of plant-plant communication (PPC) kinetics. Within a Pseudomonas aeruginosa (P. aeruginosa)-infected plant biotic stress model, the analyzer achieved: (1) spatiotemporal mapping of virulence kinetics through sensitive detection of P. aeruginosa-specific virulence factor pyocyanin, establishing infection progression timelines and tissue-specific dissemination gradients. (2) Quantification of stress-responsive signaling via dual-functionalized Au@AgNCs, revealing methyl salicylate (MeSA) release kinetics and establishing a direct correlation between pathogen invasion severity and airborne alarm signal-a calibrated defense response heretofore unquantified. (3) Real-time in situ monitoring of MeSA-mediated PPC revealed fundamental plant physiological breakthroughs: First, receiver-specific signaling reprogramming occurs where healthy plants exhibit delayed yet amplified defense hormone kinetics, contrasting sharply with the immediate response of infected emitters. Second, evolutionarily constrained coordination emerges through cross-species signaling divergence, where phylogenetic adaptations in phytohormone perception circuits drive distinct defense strategies-exemplified by Solanaceae amplification versus Poaceae suppression. (4) Validation of systemic acquired resistance (SAR) in PPC-primed plants showing 63.5% reduced infection severity and two days delayed susceptibility. This analyzer integrates molecular-scale pathogen kinetics with ecosystem-level signaling networks, advancing precision agriculture through field-deployable plant immunity diagnostics.\n\nID: 42422903\nTitle: Spectroscopic discrimination of bacterial species of variable pathogenicity through explainable machine learning.\nAbstract: Rapid and accurate identification of bacterial pathogens and their degree of pathogenicity is essential for guiding antimicrobial therapy. Current culture-based methods require a timeframe of at least 24-48 h for species-level identification alone, which often leads to substantial disease progression and increases the propensity of antimicrobial resistance (AMR). Surface-Enhanced Raman Spectroscopy (SERS) shows promise in mitigating these drawbacks by providing a fast, non-invasive, label-free method to capture the biochemical fingerprints of bacteria achievable under clinical settings. However, the molecular complexity of SERS spectra, which has been an impediment for conventional data analysis, demands robust computational frameworks for reliable species-level identification. Here, we employ a comprehensive SERS analysis scheme with supervised machine learning and explainable artificial intelligence (XAI) to discriminate five clinically relevant pathogens, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), and Enterococcus faecalis, and to probe their degree of pathogenicity from a biomarker perspective. Among the tested models - Support Vector Machine (SVM), k-Nearest Neighbour (kNN), Random Forest (RF), and a 1D Convolutional Neural Network (CNN) - CNN achieved near-perfect classification accuracy, capturing subtle and spectrally relevant variations often inaccessible to traditional algorithms. Notably, the 1D-CNN also achieved 100% discrimination between MRSA and methicillin-sensitive S. aureus - two strains of the same species differing only in resistance phenotype. To ensure transparent decision-making and eliminate the black-box nature of machine learning models, SHapley Additive exPlanations (SHAP) analysis was applied to both RF and CNN models, which facilitated the convergence of both frameworks on the same discriminatory Raman regions, revealing conserved biochemical determinants of species identity. Complementary MCR-ALS decomposition further resolved the spectra into interpretable biochemical components and provided the rubric for biochemical differentiation. Together, this study aims to demonstrate an end-to-end explainable workflow that couples SERS with interpretable AI, offering a rapid, transparent approach for pathogenic disease diagnosis.\n\nID: 42422733\nTitle: Convergent GenX biodegradation by genomically designed and functionally screened synthetic bacterial consortia.\nAbstract: GenX (hexafluoropropylene oxide dimer acid) has been introduced as a replacement for legacy polyfluoroalkyl substances (PFASs) compounds; however, accumulating evidence indicates this C6 ether-PFAS may exhibit comparable toxicity to PFOA while persisting in contaminated water supplies. Biological remediation offers genuine mineralization potential but has been constrained by the exceptional stability of carbon-fluorine bonds. Here, we demonstrate that synthetic bacterial consortia assembled through rational genomic design (GENIA) or microfluidic selection (Community G) achieve rapid GenX biodegradation through metabolic complementarity among functionally specialized taxa. Both consortia removed >80% of GenX within 3 days (GENIA: 94.6%; Community G: 80.6%), with defluorination confirmed by fluoride release (82.6 and 69.6%, respectively). First-order kinetic modeling yielded rate constants of k = 0.87 day-1 (GENIA) and k = 0.64 day-1 (Community G), corresponding to half-lives under 1.1 days. Despite pronounced taxonomic divergence, GENIA maintained a stable composition, whereas Community G underwent dramatic restructuring, enriching for specialists of Salmonella, Pseudomonas, and Stenotrophomonas. Comparative genomic analysis revealed functional equivalence, with no significant differences in PFAS-degrading gene content (p = 0.844). Multi-guild community architecture emerged wherein primary degraders (40%-60% abundance) harboring haloacid dehalogenases performed initial C-F bond cleavage, detoxification specialists possessing glutathione S-transferases and fluoride exporters (>90% universal distribution) processed toxic intermediates, and metabolic support taxa enhanced resilience. Molecular docking simulations predicted favorable binding of GenX across phylogenetically diverse dehalogenases (\u0394G = -7.0 to -8.1 kcal/mol), suggesting thermodynamic compatibility with enzymatic catalysis. These results are predictive and computational; docking cannot confirm enzymatic activity or substrate turnover. Experimental validation (enzyme kinetics, purified protein assays) is required. Critically, GENIA activity did not disrupt indigenous soil microbiomes. The data support that GENIA does not cause detectable diversity loss, a necessary but not sufficient condition for ecological compatibility. These findings establish that functional gene diversity, distributed across metabolically complementary taxa through either rational design or adaptive selection, enables efficient PFAS bioremediation, converting recalcitrant \"forever chemicals\" into biodegradable substrates through engineered microbial complexity.\n\nID: 42422472\nTitle: stackPredAMR-a stacked random forest approach improves AMR phenotype prediction for multiple species and antimicrobial agents.\nAbstract: Antimicrobial resistance is a growing global threat, creating a need for rapid and accurate antimicrobial susceptibility testing. Current phenotypic antimicrobial susceptibility testing methods rely on prior isolation and cultivation, making them time-consuming. Whole genome sequencing combined with machine learning offers a faster and cost-effective alternative, but existing approaches are often limited in species coverage, antimicrobial scope, or data availability. We developed stackPredAMR, a machine learning framework for predicting resistance to 18 antimicrobial agents in three clinically important bacterial species: Escherichia coli, Klebsiella pneumoniae, and Acinetobacter baumannii. The model uses antimicrobial resistance gene presence as input and incorporates cross-resistance patterns through a stacked architecture with two random forest layers. Benchmarking on more than 2500 publicly available whole genome sequencing datasets with linked phenotypic resistance data showed strong performance, achieving a median accuracy of 0.94, ROC AUC of 0.97, and F1-score of 0.91, outperforming previously published methods. stackPredAMR is freely available and designed to support future extension to additional species and antimicrobial agents. Source code and datasets (database-driven reference approach, sample lists, and input features) are available at WIN-KID repository (https://github.com/IKIM-Essen/WIN-KID/tree/v1.0.0.0) and the release page (https://github.com/IKIM-Essen/WIN-KID/releases/tag/v1.0.0.0).\n\nID: 42420836\nTitle: Emergence of tet(X6) and blaIMP-45 in a multidrug-resistant Pseudomonas asiatica strain isolated from chicken.\nAbstract: This study aimed to investigate a Pseudomonas asiatica (P. asiatica) strain J68 isolated from chicken in a poultry that produced tigecycline resistance gene tet(X6), carbapenem resistance gene blaIMP-45 and other multiple antimicrobial resistance genes (ARGs). Strain J68 was identified using MALDI-TOF MS and average nucleotide identity (ANI) analysis. Antimicrobial susceptibility was determined by broth microdilution method. PCR screening, conjugation assay and whole-genome sequencing were performed to characterize the strain J68. The strain J68 was identified as P. asiatica, it exhibited resistance to multiple antibiotics, including tigecycline and carbapenem. Subsequent analysis revealed that 24 antimicrobial resistance genes, including the tigecycline resistance gene tet(X6) and the carbapenemase gene blaIMP-45 were identified in the genome of the strain J68. The isolate belonged to sequence type ST15. For the first time, we report the emergence of tet(X6)- and blaIMP-45-positive P. asiatica strain isolated from a poultry source. The strain J68 exhibited resistance to last-line antibiotics, including tigecycline and carbapenems. The emergence of tigecycline resistance gene tet(X6), along with carbapenem resistance gene blaIMP-45 in strain of chicken origin is noteworthy. Our findings highlight the need for continued monitoring of resistance genes in agricultural environments.\n\nID: 42420828\nTitle: Occurrence of antimicrobial-resistant, extended-spectrum beta-lactamase and carbapenemase-producing bacterial isolates from intensive care unit environment in two hospitals of Ethiopia.\nAbstract: Intensive care unit environments are a critical reservoir of antimicrobial-resistant bacterial species and facilitate the transmission of nosocomial infections. This unit harbors multidrug-resistant organisms, thereby complicating the management of infectious diseases within clinical settings, particularly in resource-limited countries. This study, therefore, aimed to determine the occurrence and antimicrobial resistance profiles of bacteria, including Extended-spectrum beta-lactamase- and Carbapenemase-producing isolates, in the intensive care units of two hospitals in Addis Ababa, Ethiopia. A repeated cross-sectional study was conducted in Addis Ababa, Ethiopia, from July 2024 to April 2025. A total of 239 swab samples were collected from adult and neonatal intensive care unit environments during both the dry and rainy seasons. Samples were collected and processed aseptically. Bacterial identification and antimicrobial susceptibility testing were performed according to CLSI guidelines. From the total samples collected, 162/239 (67.8%) bacterial isolates were recovered from the Intensive Care Unit environment. Klebsiella pneumoniae 22/162 (13.6%) and Pseudomonas aeruginosa 21/162 (13%) were the most frequently isolated bacterial species. All P. aeruginosa were resistant to ceftazidime, while 19/22 (86.3%) and 18/22 (81.8%) of K. pneumoniae were resistant to cefuroxime and cefotaxime, respectively. All S.haemolyticus were also resistant to penicillin, and 8/12 (66.7%) of Enterococcus spp were resistant to erythromycin. Multidrug-resistant bacteria were seen in 89/150 (59.3%) of isolates. The highest multidrug resistance rate was obtained for Pseudomonas aeruginosa 18/21 (85.7%), followed by Klebsiella pneumoniae 16/22 (72.7%) and Acinetobacter spp 8/11 (72.7%). Extended-spectrum \u03b2-lactamase-producing isolates accounted for 23/105 (21.9%), and Carbapenemase-producers comprised 10/105 (9.5%). The environments within intensive care units are conducive to the proliferation of multidrug-resistant microorganisms, encompassing bacterial isolates that produce extended-spectrum beta-lactamases and carbapenemases, thereby complicating the management of infectious diseases. Consequently, it is crucial to address the issue of antimicrobial resistance in this critical setting to mitigate the incidence and dissemination of resistant bacteria, which may lead to the emergence of nosocomial infections.\n\nID: 42417593\nTitle: Molecular detection of carbapenemase genes in WHO priority pathogens from blood cultures of sepsis patients in Pakistan.\nAbstract: This study aimed to assess the antibiogram patterns of CR-GNB and to characterize carbapenemase-encoding genes among isolates obtained from patients with sepsis. A total of 3,746 blood culture samples were collected from patients with suspected septicemia and samples were processed using the BACTEC blood culture system, and all positive cultures were sub-cultured onto blood agar and MacConkey agar plates for isolation. Bacterial identification and antimicrobial susceptibility testing were performed using the VITEK 2 compact system following CLSI guidelines. Detection of antimicrobial resistance genes was carried out by PCR using gene-specific primers. Of 3,746 blood cultures, 873 (23.3%) were positive, yielding 577 (66.1%) Gram-negative isolates. Among these, 212 (24.3%) were CR-GNB, predominantly A. baumannii (41.5%), and K. pneumoniae (21.2%). MIC of meropenem among CR-GNB isolates ranged from >128 \u00b5g/mL to <1024 \u00b5g/ml. Overall, 47.2% of isolates were inhibited at 624\u00b5g/mL, followed by 38.2% at 312 \u00b5g/mL, and 12.7% at 156 \u00b5g/ml. In CR-A. baumannii, blaOXA-23 and blaNDM were detected in 71.6% and 62.5% of isolates, respectively. blaNDM was also present in K. pneumoniae (43.8%), and E. coli (40.7%).\u2009\u2009\u2009. There was a high prevalence of CR-GNB among septicemia patients, emphasizing the need for strict infection control measures to prevent their spread. Sepsis, or blood infection, is a serious and life-threatening condition that can affect people of all ages. In recent years, many of these infections have become harder to treat because some bacteria no longer respond to life-saving antibiotics called carbapenems. These bacteria are known as carbapenem-resistant Gram-negative bacteria and are listed by the World Health Organization as \u201cpriority pathogens.\u201d In Pakistan, infections caused by these resistant bacteria are increasing, but there is limited information about how common they are and what types of resistance they carry. Therefore, this study aimed to find these deadly bacteria in hospitals. This research will help doctors and health authorities understand the growing threat of antibiotic resistance in Pakistan. The results support better infection prevention, patient care, and national health policies to stop the spread of these serious pathogens.\n\nID: 42414520\nTitle: Single pass inactivation of airborne multidrug resistant bacteria using electron beam irradiation with mechanistic evidence.\nAbstract: Airborne and aerosol transmission of multidrug-resistant (MDR) bacteria pose a major challenge in healthcare environments. This study evaluated the performance of an electron-beam irradiation (EBI) system for inactivating airborne MDR bacteria under controlled laboratory conditions. To perform this assessment, clinical isolates of MDR Pseudomonas aeruginosa, Acinetobacter sp., Klebsiella sp., and methicillin-resistant Staphylococcus aureus (MRSA) were aerosolized to simulate realistic airborne transmission and subsequently introduced into the EBI system. Downstream bacterial aerosols were collected using liquid impingers and quantified by culture-based enumeration. CFU data were log\u2081\u2080-transformed prior to analysis. The EBI system reduced airborne bacterial loads by 4.01 log\u2081\u2080 for P. aeruginosa, 3.64 log\u2081\u2080 for Acinetobacter sp., 3.64 log\u2081\u2080 for Klebsiella sp., and 5.37 log\u2081\u2080 for MRSA, corresponding to disinfection efficiencies of 99.98-99.999%. Scanning electron microscopy (SEM) and elemental mechanistic study revealed morphological damage, including membrane rupture, surface collapse, and loss of structural integrity, suggesting that electron impact and electroporation may be major mechanisms of inactivation. These results demonstrate that EBI is a rapid and effective method for mitigating airborne MDR bacterial threats, with potential for deployment in healthcare, laboratory, and other high-risk indoor environments.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

This case report aimed to investigate changes in the skin microbiome of a patient with Netherton syndrome before and during dupilumab therapy, with the goal of expanding the limited evidence currently available on this topic. We report the case of a 35-year-old woman diagnosed with NS at birth, who, prior to dupilumab therapy, presented with atopic dermatitis (AD), ichthyosis linearis circumflexa, and severe pruritus. Dupilumab therapy was initiated, and skin swabs were collected from lesional sites at three different time points: at baseline, after 1\u202fmonth, and after 1\u202fyear of continuous dupilumab therapy. At baseline, a microbiome analysis revealed low microbial diversity with a predominance of Pantoea and Pseudomonas species. After 1\u202fyear, a significant increase in microbial diversity, with a predominance of Staphylococcus species and an increase in Malassezia species, was observed. Clinically, the patient experienced remission in parallel with these microbiome shifts. Post-treatment, the skin microbiome showed increased microbial diversity and re-establishment of beneficial commensals, more closely resembling healthy skin.

Here, we investigated how four genetically and phenotypically distinct Pseudomonas aeruginosa strains respond to sub\u2011MIC copper (Cu) and gentamicin (GE) stress, individually and in combination (Cu\u2009+\u2009GE). Across all strains, Cu acted as the dominant envelope\u2011active stressor, increasing biofilm biomass and extracellular DNA (eDNA) release, suppressing twitching and swarming motility, reducing quorum\u2011sensing\u2011linked protease activity, and enhancing pyomelanin production. GE alone produced limited physiological changes but modulated Cu\u2011driven outputs during co\u2011exposure, including attenuation of Cu\u2011induced eDNA release and strain\u2011specific shifts in motility and pigmentation. Early transcriptional profiling revealed consistent Cu\u2011dependent repression of lasI and mvfR, induction of the metal\u2011responsive regulator czcR, and downregulation of oprD under Cu or Cu\u2009+\u2009GE, corresponding to reduced imipenem inhibition zones when Cu was present during susceptibility testing. Combined Cu\u2009+\u2009GE exposure produced non\u2011additive, emergent effects that diverged from single\u2011stressor responses and varied across strains. These findings demonstrate that sub\u2011inhibitory Cu creates an envelope\u2011centered regulatory landscape into which gentamicin\u2011derived signals are integrated, generating heterogeneous and context\u2011dependent phenotypes. This work underscores the importance of metal-antibiotic interactions in shaping bacterial adaptation and highlights limitations of single\u2011stressor models for predicting antimicrobial behavior in combination.\n  --- END ACTUAL ABSTRACT FOR 42411263 ---\n\n- ERROR: You cited ID: 42420327 for the quote: \"Intratracheal delivery of mRNA-LNP rapidly primes lung neutrophils and macrophages into a transcriptionally pre-activated state, enhancing their phagocytic activity.\"\n  FACT: Strict Misquote Detected!

Although vaccination reduces infection rates and mortality, the vulnerable post-vaccination immunity gap can still result in infection and vaccine failure. In addition, effective vaccines are unavailable for many clinically important bacterial pathogens. Here, we report a pulmonary mRNA-lipid nanoparticle (mRNA-LNP) vaccine incorporating an ionizable lipid engineered for localized high-level expression, which elicits both rapid and durable protection against bacterial lung infections in female mice, effectively bridging this critical window of vulnerability. Intratracheal delivery of mRNA-LNP rapidly primes lung neutrophils and macrophages into a transcriptionally pre-activated state, enhancing their phagocytic activity and enabling rapid, antigen-independent bacterial clearance during the early post-vaccination period (approximately 1-7 days). Subsequently, vaccination induces potent antigen-specific adaptive responses, conferring sustained protection against both laboratory and clinical drug-resistant Pseudomonas aeruginosa strains. Single-cell transcriptomics and immune profiling reveal coordinated activation of innate and adaptive immune programs. This dual-phase immune response exemplifies a paradigm-shifting vaccine design that integrates innate and adaptive immunity to confer both immediate and long-term protection. Our findings establish a mechanistic basis for rapid antibacterial defense and highlight pulmonary mRNA-LNP vaccination as a promising strategy for combating respiratory infections.\n  --- END ACTUAL ABSTRACT FOR 42420327 ---\n\n- ERROR: You cited ID: 42402928 for the quote: \"The combination of snail mucus in STF is a highly effective remedy for infected wounds, providing complementary benefits in vivo by coupling antimicrobial activity with pro-regenerative functions.\"\n  FACT: Strict Misquote Detected!

The in vitro antimicrobial properties of STF were analyzed using checkerboard assays to determine the fractional inhibitory concentration (FIC) index. The cytotoxicity of STF was determined using the MTT viability assay using L929 fibroblasts. The in vivo efficacy of STF was assessed using a rat excisional wound model, and wound closure rates were measured at 14\u2009days post-infection. STF showed an additive interaction in the in vitro model (FIC index: 0.717-0.936) and possessed low cytotoxicity (IC50: 705.4\u2009\u00b5g/mL) compared to the individual compounds. In the in vivo model, the group treated with STF showed significantly faster wound healing and decreased inflammation compared to all other groups, including the silver sulfadiazine group. The combination of snail mucus in STF is a highly effective remedy for infected wounds, providing complementary benefits in vivo by coupling antimicrobial activity with pro-regenerative functions, and demonstrates superiority over silver sulfadiazine.\n  --- END ACTUAL ABSTRACT FOR 42402928 ---\n\n- ERROR: You cited ID: 42422903 for the quote: \"SERS analysis scheme with supervised machine learning and explainable artificial intelligence (XAI) to discriminate five clinically relevant pathogens.\"\n  FACT: Strict Misquote Detected!

Current culture-based methods require a timeframe of at least 24-48 h for species-level identification alone, which often leads to substantial disease progression and increases the propensity of antimicrobial resistance (AMR). Surface-Enhanced Raman Spectroscopy (SERS) shows promise in mitigating these drawbacks by providing a fast, non-invasive, label-free method to capture the biochemical fingerprints of bacteria achievable under clinical settings. However, the molecular complexity of SERS spectra, which has been an impediment for conventional data analysis, demands robust computational frameworks for reliable species-level identification. Here, we employ a comprehensive SERS analysis scheme with supervised machine learning and explainable artificial intelligence (XAI) to discriminate five clinically relevant pathogens, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), and Enterococcus faecalis, and to probe their degree of pathogenicity from a biomarker perspective. Among the tested models - Support Vector Machine (SVM), k-Nearest Neighbour (kNN), Random Forest (RF), and a 1D Convolutional Neural Network (CNN) - CNN achieved near-perfect classification accuracy, capturing subtle and spectrally relevant variations often inaccessible to traditional algorithms. Notably, the 1D-CNN also achieved 100% discrimination between MRSA and methicillin-sensitive S. aureus - two strains of the same species differing only in resistance phenotype. To ensure transparent decision-making and eliminate the black-box nature of machine learning models, SHapley Additive exPlanations (SHAP) analysis was applied to both RF and CNN models, which facilitated the convergence of both frameworks on the same discriminatory Raman regions, revealing conserved biochemical determinants of species identity. Complementary MCR-ALS decomposition further resolved the spectra into interpretable biochemical components and provided the rubric for biochemical differentiation. Together, this study aims to demonstrate an end-to-end explainable workflow that couples SERS with interpretable AI, offering a rapid, transparent approach for pathogenic disease diagnosis.\n  --- END ACTUAL ABSTRACT FOR 42422903 ---\n\n- ERROR: You cited ID: 42422733 for the quote: \"Synthetic bacterial consortia assembled through rational genomic design (GENIA) or microfluidic selection (Community G) achieve rapid GenX biodegradation.\"\n  FACT: Strict Misquote Detected!

Biological remediation offers genuine mineralization potential but has been constrained by the exceptional stability of carbon-fluorine bonds. Here, we demonstrate that synthetic bacterial consortia assembled through rational genomic design (GENIA) or microfluidic selection (Community G) achieve rapid GenX biodegradation through metabolic complementarity among functionally specialized taxa. Both consortia removed >80% of GenX within 3 days (GENIA: 94.6%; Community G: 80.6%), with defluorination confirmed by fluoride release (82.6 and 69.6%, respectively). First-order kinetic modeling yielded rate constants of k = 0.87 day-1 (GENIA) and k = 0.64 day-1 (Community G), corresponding to half-lives under 1.1 days. Despite pronounced taxonomic divergence, GENIA maintained a stable composition, whereas Community G underwent dramatic restructuring, enriching for specialists of Salmonella, Pseudomonas, and Stenotrophomonas. Comparative genomic analysis revealed functional equivalence, with no significant differences in PFAS-degrading gene content (p = 0.844). Multi-guild community architecture emerged wherein primary degraders (40%-60% abundance) harboring haloacid dehalogenases performed initial C-F bond cleavage, detoxification specialists possessing glutathione S-transferases and fluoride exporters (>90% universal distribution) processed toxic intermediates, and metabolic support taxa enhanced resilience. Molecular docking simulations predicted favorable binding of GenX across phylogenetically diverse dehalogenases (\u0394G = -7.0 to -8.1 kcal/mol), suggesting thermodynamic compatibility with enzymatic catalysis. These results are predictive and computational; docking cannot confirm enzymatic activity or substrate turnover. Experimental validation (enzyme kinetics, purified protein assays) is required. Critically, GENIA activity did not disrupt indigenous soil microbiomes. The data support that GENIA does not cause detectable diversity loss, a necessary but not sufficient condition for ecological compatibility. These findings establish that functional gene diversity, distributed across metabolically complementary taxa through either rational design or adaptive selection, enables efficient PFAS bioremediation, converting recalcitrant \"forever chemicals\" into biodegradable substrates through engineered microbial complexity.\n  --- END ACTUAL ABSTRACT FOR 42422733 ---\n\n- ERROR: You cited ID: 42401050 for the quote: \"This study investigated Pseudomonas urmiensis A32, an endophytic bacterium previously shown to enhance drought tolerance and disease resistance in pepper.\"\n  FACT: Strict Misquote Detected!

Among their diverse metabolites, hydrogen cyanide (HCN) is traditionally considered a potent antimicrobial compound, yet its broader role in plant-microbe interactions remains underexplored. This study investigated Pseudomonas urmiensis A32, an endophytic bacterium previously shown to enhance drought tolerance and disease resistance in pepper (Capsicum annuum). Whole-genome analysis revealed genes involved in nutrient acquisition, stress protection, and competitive exclusion, including secondary metabolite clusters for carotenoid and HCN biosynthesis. Wild-type A32 showed increased tolerance to oxidative stress, highlighting a redox-active role for HCN. Seed inoculation with A32 reduced disease symptoms and pathogen load in pepper plants challenged with Xanthomonas euvesicatoria, indicating that HCN contributes not only to direct pathogen antagonism but also to modulation of host immune responses. Biochemical analyses showed decreased activity of antioxidant enzymes and increased phenylalanine ammonia-lyase activity. Gene expression analyses revealed upregulation of PR1 and the antimicrobial peptide gene DEF1, indicating enhanced activation of defence genes. These findings demonstrate that HCN acts as a multifunctional metabolite that fine-tunes the balance between reactive oxygen species detoxification and signalling, and integrates microbial biocontrol with host immune priming. In summary, this work highlights the ecological adaptability of P. urmiensis A32 and its potential as an effective bioinoculant for sustainable crop protection.\n  --- END ACTUAL ABSTRACT FOR 42401050 ---\n\n- ERROR: You cited ID: 42414520 for the quote: \"The EBI system reduced airborne bacterial loads by 4.01 log\u2081\u2080 for P. aeruginosa, 3.64 log\u2081\u2080 for Acinetobacter sp., 3.64 log\u2081\u2080 for Klebsiella sp., and 5.37 log\u2081\u2080 for MRSA.\"\n  FACT: Strict Misquote Detected!

This study evaluated the performance of an electron-beam irradiation (EBI) system for inactivating airborne MDR bacteria under controlled laboratory conditions. To perform this assessment, clinical isolates of MDR Pseudomonas aeruginosa, Acinetobacter sp., Klebsiella sp., and methicillin-resistant Staphylococcus aureus (MRSA) were aerosolized to simulate realistic airborne transmission and subsequently introduced into the EBI system. Downstream bacterial aerosols were collected using liquid impingers and quantified by culture-based enumeration. CFU data were log\u2081\u2080-transformed prior to analysis. The EBI system reduced airborne bacterial loads by 4.01 log\u2081\u2080 for P. aeruginosa, 3.64 log\u2081\u2080 for Acinetobacter sp., 3.64 log\u2081\u2080 for Klebsiella sp., and 5.37 log\u2081\u2080 for MRSA, corresponding to disinfection efficiencies of 99.98-99.999%.

Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation. Studies demonstrate robust efficacy of probiotics against clinically challenging pathogens, including methicillin-resistant Staphylococcus aureus, multidrug-resistant Pseudomonas aeruginosa, Clostridioides difficile, Helicobacter pylori, and pathogenic Escherichia coli. Postbiotics, particularly cell-free supernatants and purified bacteriocins, offer standardized, shelf-life probiotic products. Notably, synergistic combinations with conventional antibiotics, phytochemicals, or bacteriophages enhance antimicrobial activity while enabling dose-reduction strategies to mitigate the development of resistance. However, compelling preclinical evidence, clinical translation remains constrained by the imperative for strain-specific characterization, methodologically robust randomized controlled trials, and comprehensive safety validation.

Recent evidence demonstrates that non-antibiotic strategies, including bacteriophages, peptide-functionalized nanoparticles, and plant-derived secondary metabolites (e.g., Aloin, citral), provide viable therapeutic alternatives for treating these multidrug-resistant pathogens.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic profile of *Acinetobacter baumannii* and *Pseudomonas aeruginosa* is fundamentally rooted in their capacity to subvert host immunity and endure antibiotic pressure. The literature confirms that disease results from the interaction between microbial factors and host immune responses, a concept termed the Damage Response Framework. Both pathogens exploit similar metabolic and signaling systems, including quorum sensing, to manage colonization and persistence. Emerging evidence from clinical and laboratory studies reveals that bacteriophages isolated from inflammatory environments\u2014such as the gut\u2014exhibit potent bactericidal activity. Furthermore, nanomedicine and bioactive plant compounds demonstrate high efficacy in disrupting biofilm architectures, which conventional antibiotics often fail to penetrate. These non-antibiotic modalities are essential given the rising incidence of carbapenem resistance in these ESKAPE pathogens.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Inflammatory gut environments (e.g., in sepsis models) serve as an untapped reservoir for therapeutic bacteriophages.\n*   \"Green\" nanotechnologies using magnesium or silver nanoparticles display superior antibiofilm capabilities compared to traditional antibiotics in certain experimental rat burn models.\n*   Sub-inhibitory metal stress (e.g., copper) acts as a regulatory signal that reshapes bacterial phenotypes and alters antibiotic sensitivity.\n*   Metabolic crosstalk, such as pyruvate secretion, allows *P. aeruginosa* to manipulate host antioxidant defenses, effectively acting as an immunometabolite.\n*   Explainable Artificial Intelligence (XAI) coupled with SERS provides a rapid, non-invasive method to differentiate between strains based on biochemical biomarkers, circumventing culture-dependent delays.\n*   Computational framework (TACTIC) facilitates the prediction of synergistic drug combinations even in understudied or emerging pathogens.\n*   Genomic design (GENIA) of bacterial consortia allows for the potential biodegradation of persistent compounds like GenX, showing how microbial engineering applies beyond infection to environmental detoxification.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Although, the discovery of antibiotics has saved countless of lives for the past 80 years, increasing levels of bacterial resistance to antibiotics would jeopardize the progress in clinical and agricultural sectors and may cause life-threatening situations even for previously treatable bacterial infections. Antibiotic resistance would increase the levels of poverty of low-middle income countries mostly due to extended hospital stays, higher cost of treatment and untimely deaths that directly affect the total productivity rate. Recent incidences of antibiotic resistance have been gradually increasing globally and this may potentiate horizontal transmission of the resistant gene and have been linked with cross-resistance to other antibiotic families as well. This review summarizes the global burden of antibiotic resistance from the economic viewpoint, highlights the recent incidences of antibiotic resistance mainly related to Escherichia coli, Acinetobacter baumannii, Klebsiella pneumoniae, Salmonella spp. and Staphylococcus aureus, describes the common mechanistic actions of antibiotic resistance and potential strategies to overcome antibiotic resistance.",
        "34961459": "ID: 34961459\nTitle: Phage-choline Kinase Inhibitor Combination to Control Pseudomonas aeruginosa: A Promising Combo.\nAbstract: Pseudomonas aeruginosa is one of the most prevalent opportunistic pathogens in humans that has thrived and proved to be difficult to control in this \"post-antibiotic era.\" Antibiotic alternatives are necessary for fighting against this resilient bacterium. Even though phages might not be \"the wonder drug\" that solves everything, they still provide a viable option to combat P. aeruginosa and curb the threat it imposes. The combination of antibiotics with phages, however, poses a propitious treatment option for P. aeruginosa. Choline kinase (ChoK) is the enzyme that synthesizes phosphorylcholine subsequently incorporated into lipopolysaccharide located at the outer membrane of gram-negative bacteria. Recently, inhibition of ChoKs has been proposed as a promising antibacterial strategy. Successful docking of Hemicholinium-3, a choline kinase inhibitor, to the model structure of P. aeruginosa ChoK also supports the use of this inhibitor or its derivatives to inhibit the growth of this microorganism. Therefore, the combination of the novel antimicrobial \"choline kinase inhibitors (ChoKIs)\" with a phage cocktail or synthetic phages as a potential treatment for P. aeruginosa infection has been proposed.",
        "40121200": "ID: 40121200\nTitle: Bacterial cell wall-specific nanomedicine for the elimination of Staphylococcus aureus and Pseudomonas aeruginosa through electron-mechanical intervention.\nAbstract: Personalized synergistic antibacterial agents against diverse bacterial strains are receiving increasing attention in combating antimicrobial resistance. However, the current research has been struggling to strike a balance between strain specificity and broad-spectrum bactericidal activity. Here, we propose a bacterial cell wall-specific antibacterial strategy based on an in situ engineered nanocomposite consisting of carbon substrate and decorated TiOx dots, termed TiOx@C. The fiber-like carbon substrate of TiOx@C is able to penetrate the bacterial membrane of Pseudomonas aeruginosa (P. aeruginosa), but not that of Staphylococcus aureus (S. aureus) due to its thicker bacterial wall, thus achieving bacterial wall specificity. Furthermore, a series of experiments demonstrate the specific electro-mechanical co-sterilization effect of TiOx@C. On the one hand, TiOx@C can disrupt the electron transport chain and block the energy supply of S. aureus. On the other hand, TiOx@C capable of destroying the membrane structure of P. aeruginosa could cause severe mechanical damage to P. aeruginosa as well as inducing oxidative stress and protein leakage. In vivo experiments demonstrate the efficacy of TiOx@C in eliminating 97% of bacteria in wounds and promoting wound healing in wound-infected female mice. Overall, such a bacterial cell wall-specific nanomedicine presents a promising strategy for non-antibiotic treatments for bacterial diseases.",
        "40323888": "ID: 40323888\nTitle: Cystic Fibrosis Aggregate Biofilm Model to Study Infection-relevant Gene Expression.\nAbstract: Standard pre-clinical testing methods for novel antimicrobial therapeutics used to treat chronic lung infections in people with cystic fibrosis do not reflect the environmental conditions of the hostile lung niche. Current reductionist testing conditions can lead to the progression of compounds along a preclinical pipeline without evidence of their activity under cystic fibrosis lung niche-appropriate conditions. Several approaches used to study traditional antimicrobials may not be suitable for antibiotic alternatives, including anti-virulence therapeutics like anti-quorum sensing agents and siderophore inhibitors. This protocol documents an aggregate biofilm model of Pseudomonas aeruginosa to compare resistance and infection-relevant gene expression in single-species and multi-species cultures (Staphylococcus aureus and Candida albicans), examining colony-forming unit (CFU) reductions and changes in gene expression, using algD as an exemplar. The model was optimized for small, static volumes of bacterial cultures to allow the study of novel compounds in the discovery phase of the drug development pipeline, where compound quantities may be limited. Single-species P. aeruginosa biofilms were formed in Synthetic Cystic Fibrosis Medium 2 (SCFM2) for 24 h before treatment with meropenem at different concentrations (1, 16, and 256 \u00b5g/mL) for a further 24 h. Polymicrobial biofilms were established by growing Staphylococcus aureus and Candida albicans together in SCFM2, then inoculating with P. aeruginosa for an additional 24 h and treating with meropenem. The lack of a direct connection between compound efficacy measures in pre-clinical testing and clinical trial results has cast doubt on the applicability of current laboratory screening tools. This model allows us to understand the impact of relevant factors on P. aeruginosa gene expression, including genes contributing to resistance and virulence, thereby bridging this gap.",
        "41373806": "ID: 41373806\nTitle: Interkingdom Biofilms Are Affected by Non-Antibiotic Strategies: In Vitro Study in Lubbock Chronic Wound Biofilm Model.\nAbstract: Chronic wound infections associated with resistant polymicrobial biofilms are often refractory to conventional therapies with sustained healing time. This study evaluated the efficacy of non-antibiotic treatments including Methylglyoxal-MGO-Light-Emitting Diode-LED-and Complex Magnetic Fields-CMFs-alone/combined against the biofilms of two polymicrobial mixes (MIX 1, MIX 2) containing S. aureus, P. aeruginosa and C. albicans using the Lubbock chronic wound biofilm model. At 24 h after treatment, the effects were evaluated by (i) CFU/mg reduction, (ii) Confocal Laser Scanning Microscopy-CLSM-and (iii) Scanning Electron Microscopy-SEM. All treatments significantly reduced biofilms in terms of CFU/mg in both mixes versus the controls, 24 h after treatment. MGO showed remarkable activity, especially against P. aeruginosa. In MIX 1, LED/MGO + LED was highly effective against C. albicans. The combinations MGO + LED/MGO + CMFs enhanced the antibiofilm activity compared to each single treatment against S. aureus and P. aeruginosa, in both MIX1/MIX2. CLSM and SEM analysis showed biofilm disaggregation and reduction in cell viability with combined treatments, and Candida hyphal inhibition after CMFs application. In conclusion, the results demonstrate that MGO, alone or combined with LED or CMFs, shows high efficacy against resistant biofilms in the LCWB model 24 h after treatment, and encourage further studies on potential non-antibiotic and eco-friendly strategies as future alternative therapeutic approaches for chronic wound infections.",
        "42041309": "ID: 42041309\nTitle: TXA11114: Discovery of an In Vivo Efficacious Efflux Pump Inhibitor (EPI) That Potentiates Levofloxacin Against Pseudomonas aeruginosa.\nAbstract: Objectives: Multidrug-resistant (MDR) Pseudomonas aeruginosa represents a major clinical challenge, driven in part by resistance-nodulation-division (RND) efflux pumps that reduce intracellular antibiotic concentrations and limit the efficacy of many antibacterial agents, including fluoroquinolones. The aim of this study was to identify and characterize TXA11114 as a small-molecule efflux pump inhibitor (EPI) capable of restoring the activity of the fluoroquinolone levofloxacin against MDR P. aeruginosa. Methods: The antibacterial activity of the TXA11114-levofloxacin combination was evaluated using minimum inhibitory concentration (MIC) assays against panels of clinical isolates. Mechanistic studies included levofloxacin accumulation assays, ethidium bromide accumulation assays, outer-membrane permeability measurements, and whole-genome sequencing of mutants with altered potentiation phenotypes. In vivo efficacy was evaluated in murine thigh and lung infection models, while preliminary safety and drug-like properties were assessed using cytotoxicity assays and in vitro ADME profiling. Results: The TXA11114-levofloxacin combination produced > 1 log10 CFU reductions in bacterial burden in murine thigh and lung infection models, exceeding the activity of levofloxacin monotherapy. TXA11114 markedly potentiated levofloxacin activity, producing substantial reductions in levofloxacin MIC values across multiple MDR clinical isolates, and also enhanced the activity of several additional efflux pump substrates, including \u03b2-lactams, tetracyclines, chloramphenicol, and trimethoprim-sulfamethoxazole. Mechanistic experiments demonstrated increased intracellular accumulation of efflux substrates without evidence of nonspecific membrane disruption, and mutations in ompH were associated with altered potentiation phenotypes. Conclusions: The TXA11114-levofloxacin combination produced significantly greater bacterial reductions than levofloxacin monotherapy in murine infection models. Levofloxacin was selected because fluoroquinolone resistance in P. aeruginosa is frequently driven by efflux-mediated mechanisms. While this study focused on levofloxacin potentiation, future work will evaluate additional efflux pump substrates and further define the molecular target of TXA11114.",
        "42043570": "ID: 42043570\nTitle: Bacteriophage survival and ARG dissemination from wastewater treatment plants to the environment.\nAbstract: The proliferation of antibiotic resistance genes (ARGs) represents a critical global health threat, with wastewater treatment plants (WWTPs) identified as major hotspots for resistance amplification and dissemination. While bacterial conjugation has been extensively studied, bacteriophages are emerging as significant but underestimated vectors for ARG transfer via transduction. We hypothesize that phages are capable of withstanding disinfection and exploiting diverse bacterial hosts in receiving environments, thereby functioning as active vectors of ARG dissemination rather than passive genetic reservoirs. Meta-analysis of disinfection efficacy data (n\u2009=\u200979 experimental observations, 6 technology categories) reveals significant differences in log\u2081\u2080 reduction across disinfection technologies (Kruskal-Wallis: H\u2009=\u200925.96, df\u2009=\u20095, p\u2009<\u20090.0001). Ozonation was significantly more effective than chlorination (p\u2009<\u20090.001), membrane processes (p\u2009=\u20090.003), UV irradiation (p\u2009=\u20090.005), and PAA/thermal treatment (p\u2009=\u20090.010). Phage persistence in receiving waters follows a 1-4\u00a0week timeline modulated by temperature (Q\u2081\u2080\u2009~\u20092-3), solar UV, and water chemistry. Broad host range phages have the potential to transfer ARGs to environmentally dominant genera (Aeromonas, Pseudomonas, Vibrio), and sub-inhibitory antibiotics may induce prophages and enhance bacterial competence, creating synergistic conditions that could accelerate resistome evolution. This review underscores the need for integrated approaches combining phage-targeted disinfection with ecological monitoring to effectively restrain the spread of antibiotic resistance.",
        "42072119": "ID: 42072119\nTitle: Harmine Targets Peroxiredoxin 6 to Enhance Macrophage Immunity Against Pseudomonas plecoglossicida in Ayu (Plecoglossus altivelis).\nAbstract: Pseudomonas plecoglossicida causes bacterial hemorrhagic ascites in ayu (Plecoglossus altivelis), a lethal disease characterized by abdominal distension with hemorrhagic ascites, multifocal organ hemorrhages, and histopathologically evident hepatocellular necrosis and inflammatory infiltration. The lack of effective treatments exacerbates mass mortalities, posing a significant threat to aquaculture. Given the severe pathogenesis of P. plecoglossicida infection-which involves bacterial colonization, tissue necrosis, and host immune dysregulation-effective therapeutic strategies are urgently needed. Through a screen of traditional Chinese medicine monomers, we identified harmine, an indole alkaloid derived from Peganum harmala seeds, as a potent agent against this pathogen. In vivo, harmine exhibited direct bactericidal activity by disrupting membrane integrity, as evidenced by increasing membrane permeability, and inhibiting biofilm formation. In an ayu infection model, harmine significantly increased host survival, reduced tissue bacterial load, and enhanced innate immunity by augmenting monocyte/macrophage phagocytosis and bactericidal capacity while suppressing pro-inflammatory cytokine release and apoptosis. Mechanistically, the Drug Affinity Responsive Target Stability assay was used to identify the molecular target of harmine, followed by functional validation through PRDX6-knockdown experiments. Harmine exhibited direct bactericidal activity by disrupting membrane integrity and inhibiting biofilm formation. In the ayu infection model, harmine significantly increased host survival, reduced tissue bacteria1 load, and enhanced innate immunity by augmenting monocyte/macrophage system and bactericidal capacity while suppressing pro-inflammatory cytokine release and apoptosis, the latter likely through modulation of PRDX6-mediated oxidative stress and downstream caspase signaling. Mechanistically, DARTS revealed that harmine binds to peroxiredoxin 6 (PRDX6), a multifunctional enzyme possessing peroxidase, phospholipase A2, and lysophosphatidylcholine acyltransferase activities. This binding liberates TNF receptor-associated factor 6 (TRAF6), facilitating its mitochondrial translocation and association with the ECSIT signaling integrator complex, thereby amplifying mitochondrial reactive oxygen species (mROS) production and potentiating macrophage-mediated bacterial killing. These findings establish harmine as a promising therapeutic candidate for controlling P. plecoglossicida infections and underscore the value of host-directed immunomodulation derived from natural products in aquaculture medicine.",

Our aim was to isolate bacteriophages from frozen human milk and explore the effects of sterilization and storage on bacteriophage survival. Twenty frozen human milk samples were chosen for bacteriophages isolation. Analysis showed that these samples stored for 12 months at -20\u00b0C did not contain viable bacteriophages. We artificially inoculated 10 human milk and 10 water control samples with Escherichia coli bacteriophage T4 and subjected them to various treatments. We found that ultraviolet-C irradiation significantly inactivated E. coli phage T4 (P\u00a0<\u00a00.001), with greater inactivation observed in skimmed milk (P <\u00a00.001) than whole milk. In contrast, Holder and High Temperature Short Time pasteurization had no significant effect (P\u00a0>\u00a00.05). The E. coli bacteriophage T4 was better preserved at 4\u00b0C than at room temperature over 48 h. Over 90 days of storage, bacteriophage viability was higher at -80\u00b0C (31.6%) than at -20\u00b0C (9.4%). Future work on bacteriophage isolation from human milk should consider the use of fresh samples whenever possible. Where samples are stored prior to analysis this should be at a refrigerated temperature for up to 48 h, and if samples are to be stored longer term, then -80\u00b0C is suitable for up to three months and preferable to -20\u00b0C, with storage only up to seven days.",

Global surveillance reveals a sustained increase in MDR and carbapenem-resistant P. aeruginosa (CRPA), characterized by marked regional heterogeneity and the dissemination of high-risk international clones. Conventional antibiotic-centered strategies are increasingly compromised by the interplay between intrinsic resistance determinants, including low outer membrane permeability, multidrug efflux systems, and inducible \u03b2-lactamase, and acquired mechanisms such as carbapenemases, target-site mutations, and adaptive biofilm-associated tolerance. This review presents a systems-level framework that integrates global epidemiology, resistance architecture, clinical manifestations of acute and chronic infections, pathogenicity, diagnostic innovation, and emerging therapeutic strategies into a cohesive translational perspective. Emphasizing the mechanistic convergence of resistance, persistence, and virulence reframes MDR P. aeruginosa as a dynamically regulated pathogenic network rather than solely a drug-resistant organism. Next-generation interventions are critically examined within the context of precision diagnostics and antimicrobial stewardship. Taken together, these developments signal a shift from antibiotic escalation toward integrated, precision-informed, and evolution-aware therapeutic frameworks. Sustainable control of MDR P. aeruginosa will require coordinated implementation of targeted pathogen disruption, rapid molecular diagnostics, robust stewardship strategies, hygiene measures, and antimicrobial resistance surveillance to redefine antimicrobial practice as we get closer to the post-antibiotic era.",

However, the anti-bacterial efficacy of ALA-PDT is often compromised by limited light penetration into tissues. To increase the efficacy of ALA-PDT, this study assessed its combined use with the antibiotic ceftazidime in treating chronic diabetic wounds and examined the potential mechanism of action. The results indicated that the combination of ALA-PDT and ceftazidime synergistically inhibited the growth of multidrug-resistant Pseudomonas aeruginosa. The treatment also prevented the formation of bacterial biofilm, delayed the development of antibiotic resistance, inactivated pyocyanin, and exerted a prolonged post-antibiotic effect. The mechanism supporting the synergistic antibacterial effect might involve ALA-PDT-mediated reactive oxygen species generation, leading to bacterial cell structure destruction, increased membrane permeability, and cellular ceftazidime uptake. In a full-thickness skin defect infection model in rats with diabetes, the bactericidal and wound closure rates were highest in the combination therapy group. Transcriptomics analysis of wound tissues revealed that the differentially expressed genes between the combination therapy and model groups were mainly enriched in the IL-17, AKT-STAT, and VEGF signaling pathways. Molecular biology experiments illustrated that the combination therapy might regulate the expression of IL-17, activate the JAK-STAT axis, increase p-JAK2 and p-STAT3 expression, and decrease SOCS3 expression, ultimately leading to Ki-67, CD31, and VEGF upregulation and exerting beneficial effects on angiogenesis, collagen deposition, and tissue regeneration. Overall, PDT and antibiotic combination therapy offers an efficient approach to treat infections in diabetic wounds.",

Owing to the abuse of colistin (COL), a frontline drug in clinical settings, the resistance rate of P. aeruginosa to COL has been escalating year by year, exerting a severe impact on public health. To solve this clinical problem, new therapeutic approaches are urgently required. This study initially proposes a strategy of using carvone in combination with COL to combat colistin-resistant Pseudomonas aeruginosa (COL-R P. aeruginosa). The checkerboard assay and time-kill assay validated the in vitro antibacterial action of this combination against COL-R P. aeruginosa. Furthermore, crystalline violet staining and scanning electron microscopy (SEM) confirmed that the combined treatment effectively inhibited biofilm formation. Moreover, the thigh infection model in neutropenic mice showcased the in vivo effectiveness of the combined therapy. In addition, the erythrocyte hemolysis experiment and the in vivo safety assessment revealed that the combination of carvone and COL exhibited a certain level of safety at effective concentrations. The synergistic antibacterial and antibiofilm mechanisms of carvone combined with COL may be associated with the inhibition of quorum-sensing gene expression, enhancement of bacterial inner and outer membrane permeability, and increased generation of reactive oxygen species. This study offered a new therapeutic strategy for COL-R P. aeruginosa infections.IMPORTANCEThe increasing prevalence of colistin-resistant Pseudomonas aeruginosa (COL-R P. aeruginosa) poses a significant threat to global public health, as it limits treatment options for severe infections. This study investigates the synergistic effects of carvone, a natural compound, combined with colistin (COL) to combat COL-R P. aeruginosa both in vitro and in vivo. The findings reveal that carvone can restore the susceptibility of COL-R P. aeruginosa to COL. By exploring this novel combination, the research aims to provide a potential alternative therapeutic strategy for COL-R P. aeruginosa infections. The findings could pave the way for new approaches to treat infections caused by this resilient pathogen.",

Using lettuce as a model, we investigated how tetracycline (TC) and its metabolites, anhydrotetracycline (ATC) and epitetracycline (ETC), contribute to the dissemination of antibiotic resistance genes (ARGs). TC primarily accumulated in roots and declined during translocation, whereas ATC exhibited greater persistence and became the predominant residue through in planta transformation. At environmentally relevant concentrations (\u22640.1 mg\u00b7L-1), ATC more effectively expanded the mobilizable resistome than the parent compound by inducing reactive oxygen species, activating the SOS response, increasing membrane permeability, and promoting RP4 plasmid conjugative transfer. These processes facilitated the acquisition of multidrug resistance and the colonization of plant tissues by human pathogens, including Stenotrophomonas maltophilia and Pseudomonas aeruginosa, thereby increasing ARG burdens in both rhizosphere and phyllosphere compartments. Metagenomic analysis further confirmed the coselection of nontetracycline ARGs, such as aph3'-I and catB, and the enrichment of efflux systems (acr/emr) in pathogenic bacteria. Our findings challenge the parent-compound-centered paradigm of antibiotic risk assessment by identifying ATC as a key high-risk driver of ARG dissemination in food plants and highlighting the need to incorporate transformation products into future management strategies.",
        "42146247": "ID: 42146247\nTitle: Novel Fluorinated Chlorhexidine Analogues Overcome Resistance in Gram-Negative Bacteria.\nAbstract: Antimicrobial resistance (AMR) is a critical global health challenge that compromises the effectiveness of widely used biocides such as chlorhexidine (CHX). The emergence of CHX-resistant bacterial strains, often mediated by efflux mechanisms and membrane adaptations, necessitates the development of new chemical entities capable of overcoming these resistance pathways. Here, we report the rational design, synthesis, and biological evaluation of structurally modified CHX analogues. These analogues were designed by substituting the terminal chlorophenyl rings of CHX with strategically selected aromatic groups bearing fluorine and methyl substituents to enhance membrane permeability, modulate physicochemical properties, and reduce efflux susceptibility. A library of 13 compounds was prepared using biscyanoguanidine chemistry and aniline-based substitutions via microwave-assisted synthesis, and was fully characterized by LC-MS, HRMS, and NMR. Antibacterial activity was assessed using minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) assays against a panel of Gram-positive and Gram-negative bacteria, including CHX-resistant Klebsiella pneumoniae and Pseudomonas aeruginosa strains harboring smvR, phoQ, and pmrB mutations. Selected analogues, particularly compounds 8 and 11, demonstrated potent antibacterial activity. Compound 11 showed MIC values predominantly in the range of 4-8 \u03bcg/mL across wild-type strains and retained activity in resistant isolates, with MIC values of 4-8 \u03bcg/mL in P. aeruginosa and 64 \u03bcg/mL in CHX-resistant K. pneumoniae. MBC values were generally comparable to MIC values for the fluorinated analogues, consistent with a biocidal mode of action, while chlorhexidine showed elevated MBC values in resistant strains. Molecular modeling suggests that these compounds form favorable interactions within hydrophobic regions of the SmvA efflux pump in K. pneumoniae, potentially reducing efflux susceptibility. Structure-activity relationship analysis highlights the importance of combining fluorine and methyl substituents to optimize physicochemical properties associated with antibacterial activity and resistance bypass. Collectively, these findings establish a foundation for the development of next-generation CHX-based biocides with improved efficacy against multidrug-resistant pathogens and support further translational evaluation.",
        "42150716": "ID: 42150716\nTitle: Novel dual-targeting biofilm inhibitors for potentiating antibiotic efficacy against multidrug-resistant Pseudomonas aeruginosa infections.\nAbstract: With the increasing global challenge posed by multidrug-resistant Pseudomonas aeruginosa, which utilizes biofilm formation and virulence mechanisms to exacerbate infections, there is an urgent need for novel therapeutic strategies. This work presents a novel dual-targeting biofilm inhibitor that potentiates antibiotic efficacy, offering a potent and safe candidate to combat P. aeruginosa infections. To address this problem, we developed dual-targeting biofilm inhibitors that simultaneously disrupt the quorum sensing (QS) system and iron homeostasis system via computer-aided drug design. Through integrated in vitro screening and computational ADMET profiling, HK-34b, a 1-hydroxybenzimidazolone derivative, was identified. HK-34b inhibited 89% biofilm formation (IC 50\u00a0=\u00a00.15 \u03bcg/mL) and eradicated 93% mature biofilms. It also reduced virulence factor production in P. aeruginosa, thereby impairing swarming motility. Notably, HK-34b combined with tobramycin and ciprofloxacin achieved 99% bacterial clearance, enhancing antibiotic efficacy by 400-fold and 2000-fold in murine wound models, respectively. Furthermore, HK-34b exhibited low toxicity in vivo. Pharmacokinetic studies demonstrated that HK-34b possesses favorable bioavailability (36.86%) and a wide safety window. Mechanistic studies confirmed the dual targeting mechanism of HK-34b, which inhibits the pqs system of P. aeruginosa by binding to PqsR (KD PqsR\u00a0=\u00a03.23\u00a0\u03bcM), a key virulence regulator of the QS system, and disrupts bacterial iron homeostasis through interaction with FpvA (KD FpvA\u00a0=\u00a05.56\u00a0\u03bcM), the outer membrane receptor for siderophores. MD simulations revealed stable binding of HK-34b to both PqsR and FpvA. This dual-targeting strategy demonstrates significant translational potential by employing a novel chemical scaffold, which not only avoids the cross-resistance risks associated with the shared molecular scaffolds of conventional siderophore-antibiotic conjugates, but also overcomes the drawbacks of insufficient biofilm efficacy seen with single-target inhibitors, thereby providing a sustainable approach for the treatment of multidrug-resistant P. aeruginosa infections.",

Consequently, innovative therapeutic strategies have emerged to address these challenging infections. Among them, phage therapy stands out, in which highly potent lytic bacteriophages (phages) are specifically selected to target and eradicate the responsible pathogens. In this study, Pseudomonas phage E21 was recovered from sewage, and it genetically belongs to the Lavrentievirus genus, Casjensviridae family. The genetic characterization of the isolated phage reveals the presence of highly potent lytic enzymes, which play a critical role in effectively suppressing the growth of the targeted pathogens. The phage has high stability patterns over a wide range of temperatures and pH values (65 \u2103 and 3-11). Carboxymethylcellulose was used to formulate a hydrogel for the evaluation of the bacteriophage's efficacy against biofilm-associated wound infection in a suitable animal model.

        "42160310": "ID: 42160310\nTitle: The Pseudomonas aeruginosa ribonuclease Ribocin cleaves eukaryotic ribosomes at helix 69 to inhibit host translation.\nAbstract: Pseudomonas aeruginosa employs host translation inhibition as a virulence-enhancing strategy. We previously showed that the bacterium induces cleavage of Caenorhabditis elegans large ribosomal RNA at helix 69 (H69), part of a central intersubunit bridge and the ribosomal decoding center. In this study, we demonstrate that a previously uncharacterized ribonuclease, Ribocin, is necessary and sufficient for H69 cleavage. Recombinant Ribocin cuts H69 in worm and mammalian ribosomes, indicating that H69 cleavage by P. aeruginosa is phylogenetically conserved. In worms, mammalian cells, and rabbit reticulocyte lysates, H69 cleavage results in translation inhibition. Furthermore, Ribocin contributes to bacterial virulence toward C. elegans, triggers a major host response to translation inhibition, and operates in parallel with Exotoxin A-mediated translation inhibition. These findings unveil the first known nuclease that cleaves eukaryotic ribosomes at H69 and expand the understanding of host translation-inhibition by establishing targeted rRNA cleavage as a mechanism of host attack.",

Our study introduces a novel lytic phage, CRPAP1904, exhibiting potent activity against an extremely drug-resistant P. aeruginosa ST1971 strain CRPA190. Phylogenetic and comparative genomic analyses validated the novelty of phage CRPAP1904, suggesting that it represents a new species of the Kochitakasuvirus genus. The phage CRPAP1904 has a double-stranded DNA genome of 62,430 bp base pairs, a GC content of 60.4% and predicted 83 open reading frames. Notably, no genes associated with virulence or antibiotic resistance were detected, suggesting its suitability for therapeutic applications. We further assessed the phage's host range, optimal multiplicity of infection (MOI), one-step growth curves, physicochemical stability, and antibacterial activity, which are critical for its application in environmental and clinical settings. The phage exhibits a broad host range, lysing 83% (20/24) of tested strains. The optimal MOI was 0.01 with a large burst size of 109 PFU/cell. Additionally, the phage exhibited stability over a pH range of 6-8 and at temperatures ranging from -20\u00b0C to 60\u00b0C. In vitro, the phage significantly suppresses host bacterial growth at an MOI of 100 for the first 12 h, although resistant mutants gradually emerge during prolonged exposure. In conclusion, the newly discovered phage CRPAP1904 expands phage resources and supports medicinal phage library development, advancing phage therapy and biocontrol applications in MDR-PA infections. This study isolated a novel phage, CRPAP1904, from the hospital's sewage that specifically targets an extremely drug-resistant Pseudomonas aeruginosa ST1971 strain CRPA190. Genomic analysis identified CRPAP1904 as a new Kochitakasuvirus member lacking antibiotic resistance genes and virulence factors. CRPAP1904 shows excellent stability and lytic activity against MDR-PA clinical isolates. As the first phage against Pseudomonas aeruginosa ST1971, this work expands phage resources and supports medicinal phage library development, advancing phage therapy and biocontrol applications in MDR-PA infections.",

Ma2-10 was isolated from marine sediment near King George Island, South Shetland Islands, Antarctica. In this study, we determined the complete genome sequence of this strain. The results showed that the strain has a genome size of 5,811,804\u00a0bp with a GC content of 58.5\u00a0mol%, and the coding region accounted for 89.03% of the total genome length, containing 5095 protein-coding genes.

Functional annotation of the strain's genome using KEGG and GO databases revealed that the strain's genes were significantly enriched in amino acid metabolism, carbohydrate metabolism, membrane transport, and signal transduction pathways, providing a molecular basis for its adaptation to the extreme environments of low temperature, high salt, and oligotrophy. Nine secondary metabolite biosynthetic gene clusters were identified through secondary metabolite synthesis analysis. These gene clusters indicate that the strain has the potential to produce various bioactive substances such as antibiotics and siderophores, which can be used for niche competition and stress resistance, and possesses a genetic basis for antioxidant activity and hyperosmotic tolerance.

This study assessed the antimicrobial activity of AF and three analogues against clinically relevant Gram-negative pathogens and explored tolerance mechanisms in Pseudomonas aeruginosa. Broth microdilution assays were performed on reference strains and clinical isolates of Escherichia coli, Klebsiella pneumoniae, and P. aeruginosa. Synergy studies with the most active analogue, PEt3AuCl (AF-Cl), were conducted against P. aeruginosa using polymyxin B (PMB), two efflux-pump inhibitors, and two glutathione (GSH) depletors. Gold compounds showed MICs between 4 and >64 \u00b5g/mL, with AF-Cl displaying the highest activity. AF-Cl activity was markedly enhanced by PMB and efflux-pump inhibitors, indicating that outer membrane permeability and efflux contribute to tolerance. Additionally, GSH depletion significantly potentiated AF-Cl, implicating redox homeostasis in resistance. Overall, AF-Cl shows potential against Gram-negative bacteria when combined with agents targeting membrane integrity, efflux systems, or redox balance, supporting combinatorial strategies to overcome resistance in P. aeruginosa and related pathogens.",

Analogous to the rise of antibiotic resistance, bacteria can also evolve phage resistance, a process that frequently entails fitness costs. In this study, a new lytic Pseudomonas aeruginosa phage (Henu5) was isolated and characterised. Henu5 was classified within the Caudoviricetes class and displayed good biological characteristics. The Henu5 genome possesses 92,558\u2009bp of linear dsDNA and a GC content of 49.36%. Additionally, three phage-resistant mutants, R3, R6 and R14, were isolated and investigated for adaptive trade-offs. Compared to wild-type, the phage-resistant mutants mostly exhibited fitness costs in growth, altered morphology, impaired adsorption, reduced biofilm and pyocyanin production and impaired motility, which was confirmed by transmission electron microscopy, as well as increased susceptibility to various antibiotics. In\u00a0vivo experiments revealed improved survival, alongside diminished colonisation and pathogenicity. Comparative genomics identified mutations in the genes pilQ (R3 and R14) and pilR (R6), both crucial for type IV pili (T4P) biosynthesis and potentially conferring phage resistance, with additional mutations related to the obtained trade-offs. Transcriptomic and real-time quantitative PCR proved that T4P-related genes, together with the hmgA, galU, wzy, fliG, pslA, mexH and exoY genes, were downregulated in all resistant mutants, while the qscR and mvaT genes were upregulated. Collectively, while phage resistance evolution remains an issue, this study suggests that the fitness costs of the phage-resistant mutants might be invaluable for effective phage therapies.",

Chemical phosphorus fertilizers had low efficiency and easily caused environmental risks, while conventional phosphate-solubilizing bacteria showed lower activity at low temperatures. Therefore, screening microbial resources with both cold tolerance and high-efficiency phosphate-solubilizing and growth-promoting functions was crucial for achieving green ecological restoration in alpine regions. In this study, we isolated and screened cold-tolerant phosphate-solubilizing bacteria from soils of disturbed engineering areas on the Wes-tern Sichuan Plateau. We evaluated their phosphate-solubilizing capacity and abilities to secrete organic acids, si-derophores, and indole-3-acetic acid (IAA) across a temperature gradient (6, 10, and 28 \u2103), and verified their growth-promoting effects in a pot experiment. We obtained three highly efficient cold-tolerant phosphate-solubilizing strains (P-6, P-18, and P-25), which were identified as members of Pseudomonas genus. These strains maintained good phosphate-solubilizing capacity within the range of 6-28 \u2103, among which strain P-25 exhibited the highest phosphorus solubilization (481.26 mg\u00b7L-1) at 10 \u2103. Mechanistic analysis revealed that the three strains activated inorganic phosphorus mainly by secreting organic acids and siderophores, and strains P-18 and P-25 could synthesize IAA.

The P-25 treatment performed the best, with plant phosphorus content, biomass, and plant height being increased by 109.2%, 65.2%, and 6.7%, respectively.

In view of the pesticides' toxicity, biological control represents an attractive alternative to fight this pathogen. Pseudomonas strains are known to produce diverse specialized metabolites conferring protection against several crop diseases. Next to molecules causing direct pathogen inhibition, such as antibiotics and toxins, siderophores are considered important mediators of competitive inhibition of pathogens by Pseudomonas. However, whether siderophore production plays any role in the biocontrol of P. infestans has not yet been investigated. In this study, we focused on two Pseudomonas strains, Pseudomonas donghuensis R32 and Pseudomonas chlororaphis R47, both producing the siderophore pyoverdine, and previously characterized as inhibitors of P. infestans. The aim of this study was to evaluate the role of pyoverdine in the inhibition of P. infestans by both strains. For this purpose, we created pyoverdine-deficient mutants by knocking-out pvdE, the periplasmic ferribactin exporter, in both wild-types and HCN-deletion mutants. These mutants were then tested for activity against P. infestans in different in vitro assays as well as in leaf discs. Our results indicate that pyoverdine plays no role in the inhibition of P. infestans by P. donghuensis R32 and only a minor role in P. chlororaphis R47, which was observed solely in leaf disc assays. Nevertheless, our findings demonstrate that iron competition plays an important role in the antagonistic effect of P. donghuensis R32 on P. infestans and suggest the involvement of another siderophore in the competition for iron.",

These include aspertriterpene A (AT-A,1), chaetominine (CHM,2), fumitremorgin B (FT-B,3), verruculogen (VRC,4), 12,13-dihydroxyfumitremorgin C (DH-FT-C,5), asperfumigatin (AFG,6), fumitremorgin C (FT-C,7), and verruculogen TR-2 (VRC-TR2,8). Their structures were elucidated through comprehensive spectroscopic analysis and single-crystal X-ray diffraction. Notably, AT-A(1) represents a new isolate from the genus Aspergillus sp., and its crystal structure is reported here for the first time. In vitro antibacterial assays revealed that AT-A(1) exhibited potent inhibitory activity against Pseudomonas aeruginosa and Staphylococcus aureus, with minimum inhibitory concentration (MIC) values of 2\u2009\u00b5g/mL and 4\u2009\u00b5g/mL, respectively. Further investigation demonstrated that AT-A(1) significantly suppresses bacterial biofilm formation. Moreover, when administered at a specific concentration, it can compromise the structural integrity of bacterial cell membranes and enhance membrane permeability. This study expands the chemical diversity of secondary metabolites from mangrove-derived A. fumigatus. Furthermore, this is the first report of compounds 2-8 as constituents of fungi associated with A. corniculatum, reinforcing the potential of mangrove-associated microorganisms as a prolific source of bioactive natural products.",

Although sporadic human infections such as pneumonia and meningitis have been reported in recent years, human bacteraemia caused by P. plecoglossicida has not yet been documented. Here, we report the first known case of P. plecoglossicida bacteraemia in an 89-year-old male with a history of gastrectomy and recurrent adhesive intestinal obstruction. Following treatment for intestinal obstruction and aspiration pneumonia, including a 7-day course of cefmetazole, the patient developed fever and chills. Blood cultures yielded P. plecoglossicida, which was identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), whereas urine and sputum cultures yielded Escherichia coli and methicillin-resistant Staphylococcus aureus, respectively. Antimicrobial therapy was escalated to meropenem and subsequently de-escalated to ceftazidime based on susceptibility testing, resulting in prompt clinical improvement and complete resolution of the infection. Although the relevance of bacterial replacement phenomena observed in ayu aquaculture to human infection remains speculative, bacteraemia in this case was presumed to result from bacterial translocation associated with intestinal obstruction and disruption of the intestinal microbiota following recent antibiotic exposure. This case suggests that P. plecoglossicida may act as an opportunistic pathogen in patients with disrupted gut microbiota or anatomical vulnerabilities.",

Here, we present a multiplex-compatible lateral flow immunoassay (LFIA) that integrates a universal click-chemistry conjugation strategy with highly dispersible, film-like magnetic fluorescent probes (GFDQD@Si) to enable precise diagnosis through concurrent monitoring of pathogens and protein biomarkers. GFDQD@Si combines a two-dimensional high-area reactive interface; a magnetic interlayer for target enrichment and signal amplification; a multilayer of quantum dots for fluorescence enhancement; and an outer silica shell that suppresses background fluorescence and confers superior flowability. This architecture overcomes the size disparity between bacteria and proteins, enabling efficient cocapture of multiple proteins/bacteria and achieving faster, more sensitive detection on an LFIA platform. The platform quantitatively detects two key sepsis biomarkers\u2500procalcitonin (PCT) and interleukin-6 (IL6)\u2500as well as the pathogen Pseudomonas aeruginosa, with limits of detection of 4.44 pg mL-1 for PCT, 0.94 pg mL-1 for IL6, and 7 CFU mL-1 for bacteria. Validation in 75 clinical whole-blood samples demonstrated high sensitivity, ease of operation, and robustness, underscoring its potential for real-time bedside sepsis diagnosis. By simultaneously providing dual readouts of host-response biomarkers and pathogen detection, the GFDQD@Si-LFIA platform is expected to accelerate and improve clinical decision-making for sepsis.",

This study quantified the synergistic interaction between the novel endolysin LysPFX32 and cinnamaldehyde using the fractional inhibitory concentration index (FICI). The antibacterial mechanisms of endolysin and cinnamaldehyde were investigated by assessing outer and inner membrane integrity, observing morphological changes via scanning electron microscopy (SEM), monitoring membrane permeability using confocal laser scanning microscopy (CLSM), analyzing DNA-binding capacity, and profiling transcriptional responses through qPCR. The results demonstrated significant synergy, with a FICI of 0.425, which reduced the required concentration of LysPFX32 by 16-fold. The combined treatment compromised both the outer and inner membrane integrity, resulting in the leakage of intracellular nucleic acids (127.73\u00a0ng/\u03bcL) and proteins (87.45\u00a0mg/mL). Furthermore, the combined treatment demonstrated potent anti-biofilm activity, with a 56.07% inhibition rate against biofilm formation and a 66.7% removal rate for mature biofilms, while also downregulating key genes associated with quorum sensing, biofilm development, and motility (specifically pcoI, pcoR, and fliI). In food models, the synergistic treatment effectively suppressed the growth of P. fluorescens, which reduced total volatile basic nitrogen (TVB-N) production and extended the product shelf life by 4\u00a0days. This study proposes a novel and natural biological strategy, which is mechanistically complementary, for controlling spoilage bacteria. It offers a promising natural preservative solution for the food industry.",

The compounds were evaluated against Staphylococcus aureus (MTCC 96), Escherichia coli (MTCC 111), Pseudomonas aeruginosa (MTCC 1688) and Klebsiella pneumoniae (MTCC 432). In general, coordination of the flavone ligands to Sn(iv) and Sb(iii) enhanced antibacterial activity relative to the parent ligands and the corresponding metal salts. Among the series, the Sb(iii) complexes were the most active, with complex 6 showing the highest potency, particularly against S. aureus, for which the minimum inhibitory concentration (MIC) was 2.9 \u00b5g mL-1, comparable to ciprofloxacin under the tested conditions. The expanded MIC dataset also indicated a clear organism-dependent susceptibility pattern, with S. aureus being more susceptible than the tested Gram-negative bacteria. Checkerboard analysis further revealed synergistic interactions between the Sb(iii) complexes and ciprofloxacin against S. aureus. Mechanistic studies, including scanning electron microscopy, membrane permeability analysis and propidium iodide staining, indicated that the antibacterial action of complex 6 involves disruption and permeabilization of the bacterial membrane. In addition, the cytotoxic effects of the two most active complexes, 5 and 6, were assessed in human dermal fibroblast (HDF) cells by MTT assay. Both complexes maintained high HDF viability at their respective MICs against S. aureus, indicating that their anti-staphylococcal activity was achieved at concentrations that did not cause marked cytotoxicity under the tested conditions. These findings identify Sb(iii)-bound flavonoid complexes as promising scaffolds for further antibacterial investigation.",

In this study, we isolated four phages, designated Zpj1-Zpj4, from hospital sewage samples using the clinical strain CRPA-11d as the host. Genomic analysis showed that these phages were closely related double-stranded DNA phages and lacked identifiable genes associated with lysogeny, virulence, or antibiotic resistance. Taxonomic analysis assigned them to the genus Yuavirus, subfamily Rabinowitzvirinae, family Mesyanzhinovviridae, and class Caudoviricetes. Among them, phage Zpj4 was selected for further characterization. Its biological properties were evaluated by determining genomic features, optimal multiplicity of infection (MOI), one-step growth kinetics, host range, efficiency of plating (EOP), stability, and in vitro antibacterial and anti-biofilm activities. Its therapeutic efficacy was further assessed in a CRPA-11d induced mouse model of acute lung injury by measuring bacterial burdens in the lungs, livers, and spleens, together with lung histopathology. Phage Zpj4 exhibited favorable properties, including a short latent period, a high burst size, and strong stability. It markedly inhibited CRPA-11d growth and biofilm formation in vitro. In the mouse model, phage Zpj4 treatment significantly reduced bacterial burdens in the lungs, livers, and spleens and alleviated lung tissue injury. These findings indicated that phage Zpj4 is a promising candidate for the treatment of CRPA infections.",
        "42285423": "ID: 42285423\nTitle: Advances in Quorum-Sensing Inhibitors as Novel Therapeutic Targets.\nAbstract: The growing antimicrobial resistance (AMR) has again prompted consideration of therapeutic strategies that reduce bacterial virulence rather than directly impairing viability. Quorum sensing (QS) is a density-dependent signaling network that controls the production of virulence factors, biofilm formation, metabolic reorganization, and interspecies communication in most clinically important pathogens. Quorum-sensing inhibitors (QSIs) target such coordinated behaviors by blocking autoinducer biosynthesis, signal degradation, receptor activation, or transcriptional networks downstream of these receptors. Naturally occurring, synthetic small molecules; synthetic, engineered peptide-based; and quorum-quenching-designed QSIs have been shown to suppress virulence gene expression and biofilm architecture in preclinical models of Pseudomonas aeruginosa, Staphylococcus aureus, and Vibrio species. QS disruption in the chosen systems increases susceptibility to antibiotics and alters the nature of interactions during infection, with no direct bactericidal effect. Nevertheless, the hurdles to translational progress remain considerable, including signaling redundancy, context-dependent evolution of resistance, pharmacokinetic variability, and the lack of signaling pathways specific to anti-virulence agents. Explaining the therapeutic window, resistance profile, and additive value of QS inhibition, and how to combine it with current antimicrobials, will determine whether such a strategy can play a significant role in the development of future generations of anti-infective agents.",

Considering the contemporary landscape of antibiotic resistance, alongside targeting resistance determinants, there is a need to identify novel and alternative targets for therapeutic intervention. Central metabolism plays a major role in the success of a pathogen and represents a pool of plausible drug targets. However, metabolic networks are inherently complex and often employ redundant pathways to ensure the supply of essential metabolites. In our efforts to delineate the metabolic pathways contributing to the pathophysiological fitness of A. baumannii, we focused on biosynthesis and uptake mechanisms that maintain intracellular cysteine homeostasis. Cysteine is one of the least abundant amino acids in proteins; however, it is crucial for the folding and catalytic activity of enzymes involved in diverse pathophysiological pathways. We show that A. baumannii possesses two partially redundant serine acetyltransferases involved in cysteine biosynthesis. Disruption of cysteine biosynthesis affects the intracellular cysteine pool, leading to metabolic dysregulation. The metabolic dysregulation further leads to a defect in cellular bioenergetics, oxidative stress mitigation, and antibiotic stress survival in vitro and in vivo. Combinatorial disruption of cysteine biosynthesis and cystine transport results in synthetic lethality and fitness attenuation within the host. Our work provides insights into the metabolic complexities and vulnerabilities of A. baumannii and underscores the therapeutic potential of targeting pathways that sustain cysteine homeostasis, including combination strategies, to combat infections caused by this priority pathogen.IMPORTANCEAcinetobacter baumannii is a critical nosocomial pathogen, and the rising prevalence of antibiotic resistance in this organism necessitates the identification of novel therapeutic targets. Central metabolism, particularly amino acid metabolic pathways, represents a promising yet underexplored area for such interventions. Cysteine, a sulfur-containing amino acid, is essential for the activity of different enzymes involved in key physiological processes. In this study, we demonstrate that the cysteine biosynthesis pathway plays a critical role in maintaining metabolic homeostasis and survival under antibiotic stress while exhibiting functional redundancy with the cystine uptake system in sustaining in vivo fitness in A. baumannii . Simultaneous disruption of cysteine biosynthesis and uptake results in synthetic lethality and a marked fitness defect in a murine pneumonia model. Our work reveals metabolic complexities and highlights the metabolic vulnerabilities of A. baumannii, which can be further explored for therapeutic interventions to curb infections caused by this priority pathogen.",

Given the slow progress in antibiotic development, phages have emerged as a novel therapeutic strategy against CRAB infections due to their synergistic effects with antibiotics. This study aims to explore phage-antibiotic combination therapy targeting CRAB, thereby providing a theoretical foundation for its clinical translation. Through virulence assessments in Galleria mellonella larvae and mice, CRAB110 was identified as the most virulent strain among 199 clinical CRAB isolates. Transcription analysis revealed that its enhanced pathogenicity may be associated with dysregulated pro-inflammatory responses. Using CRAB110 as the host bacterium, the newly isolated phage, P2, was selected for further study due to its high lytic efficiency and broad host range. The CRAB110 mutant strain CRAB110-2N, treated with P2, exhibited increased drug susceptibility and attenuated virulence compared to the wild-type strain. Both in vitro and in vivo experiments demonstrated that the combination of P2 with antibiotics achieved superior bacterial clearance compared to phage therapy alone. Furthermore, whole-genome analysis of CRAB110-2N revealed a mutation in its ugd. The constructed CRAB110\u0394ugd showed tolerance to P2; the quorum-sensing gene abaI was associated with phage susceptibility, with the CRAB110\u0394abaI strain displaying insensitivity to P2. These findings provide experimental evidence supporting the clinical application of phage-antibiotic combination therapy. This study focused on phage-antibiotic combination therapy targeting carbapenem-resistant Acinetobacter baumannii (CRAB), a priority pathogen designated by the World Health Organization (WHO). A highly virulent strain, CRAB110, was screened from 199 clinical isolates, and a novel, highly lytic phage, P2, was isolated from sewage samples. CRAB110-2N, a mutant strain induced by P2 exposure, displayed increased antibiotic susceptibility and attenuated virulence. Key findings showed that the combination of P2 and meropenem achieved a 99% bacterial clearance rate in vitro and exerted significant synergistic effects in vivo. Genomic analysis identified mutations in the ugd gene, and knockout experiments confirmed its correlation with phage susceptibility. Additionally, the quorum-sensing gene abaI was found to be associated with phage susceptibility in CRAB. Collectively, these results provide critical experimental evidence for the clinical translation of this phage-antibiotic combination therapy.",

Bacteriophage therapy shows promise, but single-phage use is prone to resistance. Bacteriophage cocktails can address this issue, but they are typically formulated empirically without a systematic evaluation of constituent phage interactions. We employed a comprehensive combinatorial approach to optimize three-phage cocktails against clinical P. aeruginosa isolates. From 25 candidate bacteriophages, 5 were selected based on a broad host range (\u226560% of 51 MDR P. aeruginosa clinical isolates). Ten possible three-phage cocktail combinations were systematically generated and evaluated using real-time Omnilog phenotypic microarray analysis. Phage interactions were quantified using the Highest Single Agent independence model to classify synergistic (\u0394 > +5%), neutral (-5% \u2264 \u0394 \u2264 +5%), or antagonistic (\u0394 < -5%) effects. Individual phage inhibition efficiencies ranged from 35.4% to 75.4%. Cocktail performance varied dramatically (16.1%-84.1% inhibition). Only one cocktail exhibited synergy, achieving 84.1% inhibition, an 8.7% improvement over the best individual phage. Four cocktails (40%) showed neutral interactions, while five (50%) demonstrated antagonistic effects. The optimal cocktail (Phages 1 + 3 + 4) demonstrated efficacy across six of eight diverse clinical isolates in biofilm inhibition assays (29%-63% biomass reduction, 2.7-3.6 log10 colony-forming unit reduction) and achieved 80% survival in Galleria mellonella versus 10% in infected controls. These findings demonstrate that phage cocktail optimization requires rational validation, as antagonistic interactions can occur, establishing a critical validation step before committing resources to in vivo efficacy studies. Bacteriophage cocktails are increasingly proposed as alternatives to antibiotics against multidrug-resistant bacteria, yet their development remains largely empirical. This study challenges the assumption that the combination of effective phages yields additive or synergistic benefits. Through systematic evaluation of all possible three-phage combinations from five phages, we discovered that antagonistic interactions (50%) predominated over synergistic effects (10%), with some cocktails performing worse than individual phages. Using the Highest Single Agent independence model, we established a quantitative framework for rational cocktail design that identified a therapeutically superior formulation. This approach is generalizable across bacterial pathogens and provides a critical validation step for phage therapy development. Our findings demonstrate that rational testing of phage interactions is essential before in vivo or clinical translation, potentially preventing costly failures and accelerating the development of effective phage-based therapeutics against multidrug-resistant infections.",

We present the first cross-genus atlas of biosynthetic gene clusters (BGCs) in prokaryotic fish pathogens, analyzing 1,855 genomes across 12 families and 14 genera. Using antiSMASH and BiG-SCAPE, we identified 13,626 BGCs encoding NRPS, PKS, RiPPs, terpenes, and siderophores, organized into 2,842 gene cluster families. Strikingly, 1,724 families (61%) lack close MIBiG reference homologs (designated here as MIBiG-distant clusters), representing potentially underexplored enzymatic diversity. Genus-level analyses revealed pronounced specialization: Pseudomonas, Mycobacterium, and Nocardia harbor NRPS/PKS-rich repertoires (>\u20095 BGCs/genome), while Streptococcus and Enterococcus exhibit streamlined RiPP-dominated profiles. Network analysis identified cross-taxon BGC sharing patterns consistent with horizontal gene transfer among aquatic lineages and massive within-genus expansions, with Flavobacterium RiPP families averaging 69 members. Genome-wide correlations linked GC content to BGC density (r\u2009=\u20090.41, p\u2009<\u20090.001), with genus-specific relationships ranging from r\u2009=\u20090.77 (Chryseobacterium) to r\u2009=\u2009-0.84 (Lactococcus), revealing compositional constraints on metabolic evolution. BGC distribution patterns reflected ecological lifestyle and suggested potential roles in iron acquisition, interspecies competition, and host colonization.

The obtained ORF of Lc-TBK1 is 2172 bp and encoding a 723 aa protein. Subcellular localization analysis demonstrated that Lc-TBK1 predominantly resides in the cytoplasm. Lc-TBK1 showed broad expression across multiple tissues, and its transcript abundance was particularly high in the muscle. Its transcription was significantly upregulated after challenge with poly I:C, LPS, PGN, and Pseudomonas plecoglossicida. Overexpression of Lc-TBK1 activated IRF3, IRF7, and IFNd promoters, and such promoter activation were enhanced when Lc-TBK1 co-expressed with Lc-TRAF3 and Lc-TRIF. Co-immunoprecipitation assays confirmed direct interactions between Lc-TBK1 and several key adaptors, including Lc-TRIF, Lc-MAVS_tv1, Lc-MAVS_tv2, Lc-TRAF3, and Lc-TRAF6. Subsequent co-expression analyses revealed adaptor-specific modulation of antiviral gene transcription: Lc-TRIF and Lc-TRAF3 synergistically enhanced RSAD2, IRF3, and IRF7 expression, whereas Lc-MAVS isoforms attenuated these responses. Overall, our findings demonstrate that Lc-TBK1 signaling is differentially regulated by specific adaptor proteins, providing new insights into the evolutionary conservation and diversification of antiviral immune mechanisms in teleost.",

Its presence alongside Pseudomonas aeruginosa and Escherichia coli may lead to polymicrobial biofilm-related infections. Due to rising antimicrobial resistance, alternative therapies are being explored, including luteolin, a natural flavonoid with reported in vitro antimicrobial activity. This study evaluated the in vitro antimicrobial and antibiofilm effects of luteolin against C. albicans, E. coli, and P. aeruginosa, both individually and in combination. Methods involved determining minimum inhibitory concentrations, using scanning electron microscopy, fibroblast viability tests, ELISA-based cytokine measurements, and RT-qPCR analysis of key biofilm- and quorum-sensing-related genes (luxS, lasI, and ALS1). MIC values were 0.011\u00a0mg/mL for individual strains and 0.046\u00a0mg/mL for the polymicrobial mixture. Luteolin treatment reduced microbial adherence and improved fibroblast viability compared to infected controls. Infection increased IL-1\u03b2 levels and decreased IL-10 levels, effects that luteolin partially reversed. RT-qPCR showed downregulation of selected biofilm-related genes at 2\u00d7MIC. These findings demonstrate luteolin's measurable antimicrobial and anti-biofilm effects in vitro under controlled laboratory conditions, supporting further validation in preclinical models to assess translational potential.",

This systematic review aims to evaluate the therapeutic potential of siderophore-drug and siderophore-peptide conjugates against priority multidrug-resistant pathogens, including Enterobacterales, Pseudomonas aeruginosa, and Acinetobacter baumannii, analyzing their efficacy, mechanisms of action, and implementation challenges. A systematic search was conducted in PubMed, Scopus, and Web of Science databases up to August 2025, using key terms such as \"siderophore conjugates\", \"Trojan horse antibiotics\", \"antimicrobial resistance\", and \"Gram-negative bacteria\". Preclinical and clinical studies, reviews, and meta-analyses published between 2019 and 2025 were included, selecting 55 references based on relevance to the topic, currency, and methodological quality. This review corresponds to a narrative review with a systematic literature search, developed in accordance with PRISMA guidelines. Siderophore conjugates, via the \"Trojan horse\" mechanism, effectively exploit bacterial iron uptake systems to deliver antimicrobial agents in a targeted manner. They overcome key resistance mechanisms such as \u03b2-lactamase production, porin alterations, and efflux pump activity, while reducing systemic toxicity and preserving commensal microbiota. Clinical evidence (e.g., cefiderocol) and preclinical studies confirm efficacy against multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains, with significant reductions in minimum inhibitory concentrations (MICs). However, critical challenges were identified: optimization of chemical stability and intracellular drug release, complexity in synthesis and industrial scaling under Good Manufacturing Practice (GMP) standards, and regulatory and logistical barriers in resource-limited settings. Siderophore conjugates offer a targeted therapeutic approach against multidrug-resistant pathogens by exploiting the bacteria's own iron-uptake systems. Available evidence ranges from clinical results with cefiderocol to preclinical developments with other platforms. Their application, however, faces challenges that span chemical optimization, manufacturing, regulation, and access in clinical settings.",

Stapf essential oil.\nAbstract: The urgent need for novel antimicrobial agents arises from the escalating threat of antibiotic-resistant pathogens. Tackling the resistance mechanisms through the application of resistance modifying agents in combination to antimicrobials represents an effective strategy to combat antimicrobial resistance and to enhance the antimicrobial activity. Screening of plant extracts, essential oils and their active compounds for potential resistance modifying properties has proven effective on both a small and large scale. In this study, we define the metabolomic profile of essential oils extracted from different parts of Cymbopogon citratus (DC.) Stapf (lemongrass), and characterize their antioxidant and virulence attenuating activities. The major active ingredients of essential oils extracted from different parts of Cymbopogon citratus (lemongrass) were identified by GC-MS analysis. The minimum inhibitory concentration (MIC) of the essential oils against P. aeruginosa PAO1, Staphylococcus aureus ATCC 6538, and Candida albicans ATCC 10,261 was determined using the broth microdilution assay. Antibiofilm and antiprotease activities were phenotypically evaluated for the extracted lemongrass essential oils for the same standard strains and clinical isolates for the same microbes. Also, the effects on microbial virulence were validated by RT-qPCR against a subset of genes regulating biofilm, quorum sensing, and stress response in P. aeruginosa, and S. aureus. Furthermore, the antioxidant activities of the different essential oils extracted were evaluated using DPPH, \u03b2-carotene/linoleic acid and FRAP methods. GC-MS analysis of the essential oils of Cymbopogon citratus revealed the presence of 47 different compounds distributed in the different plant organs. Active constituents such as geranial, neral, myrcene, nerolic acid, linalool, iso-citral, trans iso-citral, and neryl acetate were more abundant in the essential oil extracted from leaves (89.77%), followed by stems (82.92%) and finally roots (52.02%). S. aureus, and C. albicans were more sensitive to C. citratus essential oils than Gram negative P. aeruginosa. Incorporation of sub-MIC doses of essential oils into the culture media was sufficient to disrupt the formation of microbial biofilms in P. aeruginosa, S. aureus, and C. albicans, and to inactivate the proteolytic activities of microbial proteases. The essential oils of C. citratus showed promising and broad-spectrum biofilm eradicating activity. Sub-MIC doses of lemongrass oil dramatically reduced the expression of relA, pslA, and spoT in P. aeruginosa, and agrA, icaA, and sigB in S. aureus indicating a broad-spectrum anti-virulence activity. Our study identifies C. citratus essential oils as potential virulence-attenuating agents. Essential oils extracted from the leaves, stems, and roots of C. citratus exhibited significant antimicrobial, anti-biofilm, anti-virulence, and antioxidant activities, effectively combating microbial resistance. These findings suggest that C. citratus essential oils could be a valuable natural alternative in the fight against resistant pathogens.",

We aimed to identify novel phosphatase checkpoints in host defense, elucidate their molecular mechanisms, and validate their druggability using small-molecule interventions. We performed a genome-wide RNAi screen of 166 phosphatase genes in C. elegans infected with Pseudomonas aeruginosa (PA14) to identify key regulators. The molecular mechanism was dissected using yeast two-hybrid screening, Co-IP, and mutagenesis assays. Furthermore, a small-molecule screen was performed to identify compounds capable of interfering with PTP-4 function, followed by Surface Plasmon Resonance (SPR), molecular docking, and structural biology approaches to characterize compound-PTP-4 interactions. PTP-4 was identified as a critical negative regulator of immunity. Genetic deficiency of ptp-4 significantly enhanced host resistance via hyperactivation of the p38 MAPK (PMK-1) pathway. Mechanistically, PTP-4 physically interacts with ATLN-1, an ER-shaping GTPase, through its phosphatase domain, thereby suppressing immune activation. Crucially, baicalin was identified through compound screening as an inhibitor of P. aeruginosa infection. Structural and biochemical analyses revealed a dual mechanism of action: baicalin directly binds to the PTP-4/ATLN-1 interface with high affinity (KD = 28.69\u00a0\u03bcM) to allosterically disrupt their complex formation, while concurrently downregulating PTP-4 protein expression. This \"dual-hit\" inhibition mimics the genetic loss of ptp-4, effectively unleashing the innate immune response. Our study uncovers the PTP-4/ATLN-1 axis in the control of P. aeruginosa infection. Importantly, we provide the first proof-of-concept that this axis is a druggable target. By demonstrating that baicalin boosts host immunity through the specific dismantling of the PTP-4/ATLN-1 complex, we highlight a novel therapeutic strategy for combating bacterial infections.",

The nonulosonic acid C8-epimeric 5,7-di-N-acetyllegionaminic acid (8-epi-Leg5,7Ac2) is a component of the K-locus 49 (KL49) capsule of hypervirulent Acinetobacter baumannii, and its epimerization is proposed to be mediated by ElaA, ElaB, and ElaC. We identified a KL49 strain that induces lethal sepsis in mice and found deletion of elaA, elaB, or elaC abolished lethality and markedly reduced capsule production. Crystal structures of ElaB, ElaA, and ElaC revealed conserved N-acetyl recognition underlying CMP-Leg5,7Ac2 synthesis and regioselective C8 epimerization. Together, these genetic, structural, and in vivo findings identify ElaABC as potential antivirulence targets in emerging hypervirulent KL49 A. baumannii strains.",

However, whether and how such social roles emerge within clonal populations of a single bacterial strain remain unclear. Here, we investigate whether and how such social roles emerge within clonal populations of a single bacterial strain. Using single-cell transcriptomics, we analyzed the response of clonal Pseudomonas aeruginosa PAO1 biofilms to colistin and identified 13 transcriptionally distinct subpopulations, with siderophore biosynthesis genes enriched in one subpopulation. Upon colistin exposure, these genes were specifically upregulated in this subpopulation, whereas their cognate receptor genes were ubiquitously expressed across all subpopulations. Through genetic and physiological experiments, we demonstrate that siderophore sharing between the subpopulations confers cross-protection against colistin by enhancing resistance in a growth-independent manner, as well as by promoting biofilm formation and stability. Therefore, the spontaneous emergence of siderophore producers and non-producer subpopulations, along with their intercellular interaction mediated by siderophore sharing, constitutes a strategy for colistin protection.IMPORTANCEThis work provides a single-cell transcriptomic atlas of P. aeruginosa biofilms and reveals transcriptional heterogeneity within the clonal population. Colistin treatment markedly reshaped the subpopulation structure, with a siderophore biosynthesis-related subpopulation being significantly enriched, while siderophore receptor genes were broadly expressed across all subpopulations. This pattern of \"production specialization\" and \"reception universalization\" extends the applicability of public goods theory to clonal bacterial populations at the single-cell level and further reveals the important role of siderophore sharing in mediating cross-protection among genetically identical subpopulations. These findings deepen our understanding of the complexity of bacterial behaviors and provide potential therapeutic targets for combating biofilm-associated infections.",
        "42318016": "ID: 42318016\nTitle: Microbial and host innate immune factors affecting the persistence of Staphylococcus aureus in cystic fibrosis airways.\nAbstract: Chronic bacterial respiratory infections by Staphylococcus aureus are a hallmark of cystic fibrosis (CF) lung disease, affecting up to 80% of all people with CF by their mid-teens. S. aureus is able to survive and persist in the CF lung despite robust neutrophilic inflammation. As neutrophils are the immune system's front line of defense against bacteria, the persistent nature of S. aureus infections in CF indicates both a defect in the ability of neutrophils to kill S. aureus and an enhanced ability of the bacteria to survive. S. aureus persistence in the CF lung is driven by both microbial and host, genetic and microenvironmental, factors. There doesn't seem to be one unifying feature that makes S. aureus more virulent in the CF lung as several factors have been proposed to aide its survival. These include increased resistance to antibiotics, the ability to form small colony variants, biofilm formation, co-infection with Pseudomonas aeruginosa, and several virulence factors such as the accessory gene regulatory system, leukocidins, and staphylococcal protein A. A variety of host factors also affect the ability of neutrophils to kill S. aureus in the CF lung. Defects in the function of the cystic fibrosis transmembrane conductance regulator, the genetic cause of CF, affect phagolysosomal killing and lead to increased formation of neutrophil extracellular traps, which are less effective at killing S. aureus. Additionally, data suggest that factors within the CF lung microenvironment also affect neutrophilic killing of S. aureus. However, more research is needed to clearly identify what these environmental factors may be. This review article summarizes the current knowledge on the clinical relevance of S. aureus lung infections in CF, on microbial and host mechanisms promoting S. aureus survival in the CF lung, and on details of neutrophil-S. aureus interactions in CF. By understanding how S. aureus is able to survive in the CF lung and why neutrophils are unable to kill this bacterium, it could be possible to identify potential therapeutic targets to alleviate the consequences of S. aureus respiratory infection in CF.",

However, in environments such as soil, where microbial populations are spatially fragmented, sparse, nutrient-limited, and subject to mass transport, the mechanisms that enable QS-dependent processes remain incompletely understood. Here, we investigate the regulation of a secreted redox-active metabolite, phenazine-1-carboxylic acid (PCA), in Pseudomonas synxantha 2-79, a model rhizobacterium, under phosphorus (P) limitation, a persistent stress in many soils. Using a combination of microscopy and molecular genetic approaches, we show that P limitation sensitizes the QS activation threshold by an order of magnitude, enabling phenazine induction at relatively low population densities compared with P-replete conditions. This induction is abolished in QS-deficient mutants and restored by the addition of exogenous acyl-homoserine lactone (AHL), demonstrating that QS remains essential, but its threshold becomes environmentally tuned. Under P limitation, spatial confinement and pore saturation levels further shape the timing and location of induction, illustrating how physical structure and nutrient stress can modulate bacterial activities. Moreover, P stress confers both collaborative and competitive advantages, enabling P. synxantha to undergo low-cell-density AHL cross-induction with related Pseudomonas spp. and to suppress other rhizobacteria. Lastly, on plant roots, phenazine biosynthetic genes are more strongly induced under P limitation. These findings illustrate how the nutrient status of an environment can modulate the onset of QS, enabling quorum-regulated behaviors to activate at lower thresholds.",

Medicinal plants are sources of antimicrobial agents for the treatment of bacterial, parasitic, and fungal infections. In this research, we examined antimicrobial, antibiofilm, and efflux pump inhibition activity of the methanolic extracts of the stem barks of Milicia regia and Entandrophragma angolensis. Crude methanolic extracts were assessed using three distinct assays: the high-throughput spot culture growth inhibition (HT-SPOTi) assay for bacterial growth inhibition, a crystal violet-based antibiofilm screening assay to quantify their biofilm\u2011inhibitory activity and the ethidium bromide accumulation assay for evaluating changes in bacterial cell membrane permeability against Mycobacterium smegmatis, Mycobacterium aurum, Staphylococcus aureus, and Pseudomonas aeruginosa. The preliminary qualitative phytochemical screening suggested the presence of tannins, flavonoids, terpenoids, glycosides, alkaloids, and saponins. The minimum inhibitory concentrations for extracts against S. aureus, P. aeruginosa, M. aurum, and M. smegmatis were 250, 125, 500, and 250\u2009\u03bcg/mL, respectively, and for E. angolensis: 125, 125, 500, and 500\u2009\u03bcg/mL, respectively.

These can be acute or persistent and can exacerbate existing chronic diseases, such as cystic fibrosis, COPD and lung cancer. In this review, we use Pseudomonas aeruginosa as a model organism that demonstrates the molecular complexity of host-pathogen interactions during lower airway infection. Specifically, we focus on RNA modifications and show that they, on the one hand, regulate bacterial fitness and pathogenicity, and on the other control the execution of an effective host innate immune response. Furthermore, we examine the role of epigenetic and epitranscriptomic modifications in the immune dysregulation observed in sepsis, with an emphasis on sepsis-induced lung injury. Innate immune memory -\u00a0a cellular adaptation mechanism to primary microbial stimulation - results in training or tolerization of host cells towards secondary immune challenges. While fundamentally grounded in epigenetic and metabolic reprogramming, we propose that it can crosstalk with epitranscriptomic regulation. To overcome limitations imposed by animal models when investigating microbe-induced epitranscriptomic dynamics, we highlight physiologically-relevant in vitro tissue models that can complement work performed in vivo. Ultimately, a detailed understanding of the RNA modification landscape regulating host-pathogen interactions will help us identify new therapeutic targets and molecular pathways to better manage the clinical symptoms of bacterial respiratory infections and address the growing challenge of antimicrobial resistance.",

The present study aimed to investigate the prevalence and molecular epidemiology of blaNDM-1 among 50 Pseudomonas aeruginosa isolates causing bloodstream infections in cancer patients in Egypt, and to characterize their antimicrobial resistance profiles, carbapenemase production, and biofilm-forming capacity. Antimicrobial susceptibility testing, minimum inhibitory concentrations, multiplex PCR for carbapenemase genes, biofilm assays, and multilocus sequence typing (MLST) were performed. Two representative isolates underwent whole-genome sequencing (WGS) to determine the genetic context of blaNDM-1. All isolates exhibited multidrug-resistant or extensively drug-resistant phenotypes. Carbapenem resistance was detected in 80% (n\u2009=\u200940) of isolates, and blaNDM-1was identified in 64% (n\u2009=\u200932), comprising 80% of carbapenem-resistant isolates. Strong biofilm formation was significantly associated with blaNDM-1 carriage (P\u2009=\u20090.0115). MLST analysis of a subset of blaNDM-1-producing isolates (n\u2009=\u200910) revealed two sequence types among blaNDM-1-producing isolates: ST308 (n\u2009=\u20096) and ST773 (n\u2009=\u20094). These findings indicate the dissemination of high-risk Pseudomonas aeruginosa clones ST308 and ST773 carrying blaNDM-1 in Egypt. WGS showed chromosomal integration of blaNDM-1within integrative and conjugative elements (ICEs) containing IS91-family transposases and multiple additional resistance genes. However, the relatively small sample size and the limited number of isolates subjected to WGS may restrict the generalizability of these findings. The presence of blaNDM-1 within mobile genetic platforms highlights the ongoing evolution and dissemination of CRPA in this clinical setting and calls for enhanced surveillance, as these lineages may act as reservoirs for the acquisition and dissemination of diverse antimicrobial resistance determinants via their putative ICE.",

The study of quorum sensing (QS), the bacterial communication system that coordinates important events in an infection, opens a new avenue for treating infections. QS helps in biofilm formation which acts as a physical barrier and alters the microenvironment which traps the molecules or slows down the antibiotic diffusion making them less effective. Since the standard drugs are not very effective against bacteria anymore, demand for the discovery of other alternatives arises. Phytochemicals extracted from commonly used plants like Coleus amboinicus, known to have antimicrobial properties, can be used to develop novel drugs against quorum sensing and hence suppress bacterial infection. Here, we have identified a set of phytochemicals from C. amboinicus whose drug-like properties were predicted using SwissADME and their interactions with the targets involved in QS in Pseudomonas aeruginosa, Vibrio harveyi and Chromobacterium violaceum were studied by performing molecular docking using PyRx software. Beta-amyrin, chrysoeriol and apigenin were found to be the top scored molecules with docking scores of -9.3, -11.3, and -\u200911.1\u00a0kcal/mol respectively, and were considered for molecular dynamics simulation using GROMACS software. This was followed by in vitro tests such as Agar well diffusion, Scanning electron microscopy, Pyocyanin assay and Crystal violet assay. Erythromycin was used as the standard drug and as a positive control to validate the results. Based on both in vitro and in silico studies, the phytochemicals from C. amboinicus have the potential to be inhibitors of quorum sensing targets. These findings are preliminary and should be interpreted as hypotheses to be tested experimentally rather than as established mechanisms.",

In this study, we examined and optimised P. putida KT2440's ability to utilise products of the degradation of polyethylene (PE), the most used and disposed plastic. PE degradation creates over 200 molecules that vary in oxidation level and, thus, chemical properties. Among those, long-chain alcohols represent one of the most challenging fractions to process due to their poor solubility. Using them as feedstock for microbial growth would close the plastic-derived carbon cycle, reducing environmental impact. First, we discovered that P. putida KT2440 can use the long-chain alcohols, 1-hexadecanol and 1-eicosanol, as the sole carbon and energy source. Using adaptive laboratory evolution (ALE), we generated variants with improved growth rates on such substrates. Mutations that became fixed during ALE provided insights into the mechanism, highlighting the importance of cell-substrate interaction. By heterologously expressing a hydrocarbon transporter-encoding gene, we successfully reproduced the ALE-derived phenotype, suggesting that the bottleneck in long-chain alcohol utilisation lies in uptake rather than substrate transformation. These findings lay the groundwork for the potential application of P. putida KT2440 for the valorisation of PE degradation products.",

As an alternative to chemical treatments, microorganisms offer promising biocontrol potential. This study investigates nine Pseudomonas strains isolated from maple sap for their antifungal activity and genomic features. Whole-genome sequencing followed by comparative genomic analysis identified five distinct Pseudomonas species, including two previously uncharacterized taxa for which we propose the names Pseudomonas acericola sp. nov. and Pseudomonas edsoni sp. nov., in accordance with the nomenclatural guidelines of the SeqCode. Strain distributions from metagenome recruitment suggest they originate from sapwood, and previous metataxonomic data show that the amplicon sequence variant matching P. edsoni predominated maple sap samples. Genome mining using antiSMASH and BAGEL4 identified gene clusters associated with the synthesis of antifungal compounds, such as hydrogen cyanide, siderophores, cyclic lipopeptides, and ribosomally synthesized peptides. Antifungal assays demonstrated inhibitory activity against food spoilage fungi, with P. edsoni strains being active against Kluyveromyces lactis. The absence of activity in the cell-free supernatant and the presence of Type VI secretion systems in the genomes point toward contact-dependent mechanisms. Collectively, these findings reveal previously unrecognized taxonomic diversity and ecological specialization in maple sap-associated Pseudomonas, providing a basis for the rational development of Pseudomonas-based antifungal strategies in maple syrup production and quality control.",

This has prompted increasing interest in alternative or complementary antimicrobial strategies, including the use of essential oils (EOs), which are complex mixtures of plant-derived volatile compounds with documented biological activities. This review aims to summarize and discuss the current evidence on the antimicrobial, antibiofilm, and anti-virulence activities of EOs against P. aeruginosa, with particular emphasis on their mechanisms of action, synergistic interactions with antibiotics, and limitation to the possible clinical applicability. A large number of studies, mainly conducted in vitro, indicate that EOs and their major constituents can impair P. aeruginosa viability and pathogenicity through multiple mechanisms. In addition, several EOs or purified terpene components exhibit synergistic effects when combined with conventional antibiotics, enhancing antimicrobial efficacy. However, in vivo evidence remains limited, largely restricted to topical infection models, while clinical studies in humans are currently lacking. Significant challenges related to chemical variability, toxicity, safety, standardization, and regulatory classification also emerge from the literature. Although EOs show considerable promise as antimicrobial and anti-virulence agents against P. aeruginosa, their current role should be viewed primarily as adjunctive or alternative strategies rather than as standalone systemic therapies. Future progress will depend on the development of standardized and safer formulations, advanced delivery systems, and well-designed in vivo and clinical studies.",

In the current study, we applied a hypothesis-generating framework primarily based on integrating four different datasets and applying batch correction. Weighted Gene Co-Expression Network Analysis (WGCNA) was performed in parallel with differential expression analysis using limma. Therefore, we aimed to identify potential biofilm-associated gene candidates. Significant candidate genes were subjected to functional analysis and gene ontology, followed by the construction of a protein-protein interaction network using STRING. The Pseudomonas Genome Database was used to highlight the candidate genes. A total of 271, 687, 533, and 277 significantly up-regulated differentially expressed genes (DEGs), as well as 306, 985, 472, and 312 significantly down-regulated DEGs, resulted from the exploratory analysis. Through WGCNA/limma integration, 223 common significantly up-regulated/positively correlated gene candidates were identified. Functional analysis results showed significant enrichment in virulence-related pathways, such as biofilm formation (PA0083, PA0084, hcp1, hcpC, pilH, pilI, pilJ, vfr, pqsA, pqsB, pqsC, pqsE, PA1657, and PA1658). In addition, other virulence-related pathways, such as quorum sensing, phenazine biosynthesis, the bacterial secretion system, and secondary metabolite biosynthesis, were enriched. In conclusion, our hypothesis-generating integrative analysis identifies candidate genes and potential pathways associated with biofilm formation, virulence, and other processes in P. aeruginosa. In light of this, we point out that all candidate genes presented in this study remain hypothesis-generating. Further validation is recommended, including large-scale in silico analyses and in vitro experimental studies.",

The rapid emergence and dissemination of carbapenem-resistant bacterial strains are mainly due to horizontal gene transfer (HGT) within or between bacterial cells via the mobilome. The aim of this article is to discuss the role of mobile genetic elements (MGEs) that capture and disseminate resistance determinants of carbapenem antibiotics, as a comprehensive review integrating the combined role of plasmids, transposons and integrons. It attempts to systematically fill the gap by investigating the role of these MGEs in the acquisition, mobilization and dissemination of genes encoding carbapenemases across clinically important bacteria. Various types of plasmids such as IncF and IncH in Klebsiella pneumoniae, IncL/M in Enterobacter cloacae, IncX3 in Escherichia coli and IncA/C2 in Salmonella enterica carry important genes encoding carbapenemases. The rapid distribution of transposons among bacterial species is one of the main contributing factors in the dissemination of carbapenem-resistant isolates. Transposons including Tn4401 carrying blaKPC in K. pneumoniae and Tn1721 carrying blaKPC in E. coli; Tn2006, Tn2007, Tn2008 and Tn2009 carrying blaOXA-23 in Acinetobacter baumannii; Tn1696 carrying blaIMP-4 in Pseudomonas aeruginosa; Tn125 carrying blaNDM in E. coli; and Tn6306 carrying blaIMI in Raoultella ornithinolytica encode different types of carbapenemases. Integrons mainly belonging to class 1 capture resistance determinants for metallo-carbapenemases such as NDM-, VIM-, SIM- and IMP-type enzymes in P. aeruginosa, A. baumannii, K. pneumoniae and E. coli and can promote the transcription and expression of these determinants. These findings are useful for understanding the genetics of carbapenem resistance and additional knowledge on MGEs may provide avenues for screening of resistance to these antibiotics in clinical settings.",

This analysis focuses on the ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species), which are prioritized by the World Health Organization (WHO) and represent a significant cause of nosocomial infections due to their extensive drug resistance. We provide an in-depth review of the global prevalence and specific antibiotic-resistant mechanisms of these pathogens. Due to the decline in the traditional antibiotic development pipeline, accelerated development of alternative therapeutic strategies is essential. The review comprehensively discusses innovative non-traditional therapies currently being explored to bypass traditional antibiotic limitations, such as phage therapy, antimicrobial peptides (AMPs), anti-virulence therapies, fecal microbiota transplantation (FMT), and targeted CRISPR-based approaches. Addressing the ESKAPE challenge requires a concerted, multi-sectoral strategy guided by the One Health principle, focusing on enhancing public awareness, improving surveillance and research, optimizing judicious antibiotic use, and cultivating sustainable investment in novel interventions.",

Effective definitive antimicrobial therapy for pneumonia relies on accurate identification of bacterial pathogens and their resistance patterns. Therefore, this study aims to evaluate the distribution bacterial pathogens and their antimicrobial resistance patterns, as well as clinical factors associated with outcomes among hospitalized pneumonia patients. Methods: This retrospective cohort study was conducted at Dr. Hasan Sadikin General Hospital, Indonesia, and included adult patients hospitalized with pneumonia between January and December 2024. Clinical, demographic, microbiological, and outcome data were extracted from electronic medical records and the laboratory system. Bacterial distribution, antimicrobial patterns, and clinical outcomes were analyzed descriptively and compared across pneumonia types. Multivariable regression analyses were performed to identify factors associated with in-hospital mortality and length of hospital stay. Results: A total of 662 hospitalized pneumonia patients were included with Gram-negative bacteria (i.e., Klebsiella pneumonia, Acinetobacter baumannii, and Pseudomonas aeruginosa) identified as the most common pathogens. Carbapenem-resistant Acinetobacter baumannii (CR-Ab) and Klebsiella pneumoniae (CR-Kp) were the most frequently identified resistant pathogens, particularly in hospital-acquired (HAP) and ventilator-associated pneumonia (VAP). HAP and VAP were independently associated with higher in-hospital mortality and longer hospital stay compared to community-acquired pneumonia (CAP). In addition, CR-Ab and difficult-to-treat Pseudomonas aeruginosa (DTR-Psa) were associated with prolonged hospitalization. Conclusions: Type of pneumonia, bacterial pathogens and resistance patterns were associated with in-hospital mortality and length of hospital stay. These findings highlight the importance of ongoing microbiological surveillance, antimicrobial stewardship, and infection prevention strategies to optimize pneumonia management and clinical outcomes.",

A key component of various pyoverdines is the presence of one or more copies of L-\u03b4-N-formyl-\u03b4-N-hydroxyornithine (fOHOrn) as an iron-binding residue. In this study, we have developed an improved preparation of a derivative of fOHOrn that is suitable for use in solid-phase peptide synthesis, incorporating a novel N-oxidation protocol and a mild final deprotection with HCl/hexafluoroisopropanol (HFIP) that circumvents the unexpected deformylation of the fOHOrn side chain under acidic conditions. We have also devised a synthesis of the cyclic peptide component of pyoverdine D exploiting a selective side-chain deprotection strategy with HCl/HFIP that allows the application of readily available amino acids with standard tert-butyl side-chain protection and which facilitates the cyclisation step. These innovations open the way towards the convergent preparation of various pyoverdines and also other natural products that contain fOHOrn residues.",

In this scenario, biotransformation has emerged as a complementary innovation strategy for antimicrobial discovery because it expands the chemical space around bioactive scaffolds through selective enzymatic or whole-cell modification. Among the available biocatalysts, fungi are especially attractive due to their metabolic plasticity and broad enzymatic repertoire, including cytochrome P450 monooxygenases, unspecific peroxygenases, laccases, peroxidases, and hydrolases. Current evidence shows that fungal systems can mediate regio- and stereoselective transformations of xenobiotics, aromatics, steroids, terpenes, and lipids, generating structurally refined metabolites of pharmacological and biotechnological interest. This narrative review discusses where fungal biotransformation currently stands as a platform for antimicrobial innovation, highlighting representative enzyme-characterized examples, the main fungal groups and catalytic systems involved, and the experimental workflows used to evaluate these processes. Particular emphasis is given to assay design with growing cells, resting cells, and isolated enzymes, as well as to analytical monitoring by time-course sampling, LC-HRMS/MS, dereplication, molecular networking, isolation, and structural elucidation. Overall, fungal biotransformation is presented as a discovery-enabling platform that links biodiversity, enzymatic catalysis, analytical chemistry, and biological prioritization in the search for new anti-infective molecules.",

A specific form termed Quorum Sensing (QS) has received considerable attention since its discovery in the marine symbiont Aliivibrio fischeri. QS-controlled microbial functions are associated with bacterial virulence, pathogenicity, host-microbe interactions, and biofilm development. Interference in these signalling systems can modulate microbial virulence and pathogenicity, and microbial infection caused by drug-resistant pathogens. Plant-derived phytochemicals are considered a promising candidate, with coumarins emerging as significant plant-derived signalling molecules shaping microbiome dynamics and pathogen behaviours from a broad spectrum of ecosystems. Here we explored the role of natural and synthetic coumarin compounds in the control of signalling and virulence traits in Pseudomonas aeruginosa and other priority bacterial pathogens, including the fungal opportunist Aspergillus fumigatus. We uncovered an important 'hydroxylation-bias' favouring coumarin, umbelliferone (7-OH), and 6-hydroxy-coumarin (6-OH) in the specific competitive inhibition of the Pseudomonas Quinolone Signal (PQS), associated with reduced activity of a PqsR translational fusion and suppression of pyocyanin production. Conversely, while esculetin (6,7-OH) was most effective at Acyl Homoserine Lactone (AHL) QS biosensor inhibition, it did not affect PQS production. Anti-biofilm activity of coumarins against P. aeruginosa was independent of initial attachment but linked to changes in exopolysaccharide production. As the very real threat posed by antimicrobial resistance persists, these data support a role for phytochemicals such as coumarins in delivering an ecological solution to dysbiosis in the host-microbe interaction.",

This study is aimed to investigate temporal trends and describe the epidemiological characteristics of MDR bacteria isolated in hospitalized children from 2017 to 2023 in an academic children's hospital in Italy. We included all bacterial isolates obtained from blood or cerebrospinal fluid (CSF) cultures collected from pediatric patients evaluated in both inpatient settings and the Emergency Department between 1 January 2017 and 31 December 2023. The study included the main ESKAPE pathogens (including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) and other relevant MDROs such as Escherichia coli. Data were extracted from the hospital microbiology data warehouse, and resistance proportions were calculated as MDR isolates over total isolates for each pathogen. Associations between year, patient characteristics, ward type, and MDRO infections were evaluated using univariable and multivariable logistic regression; trends over time were evaluated using the Cochrane-Armitage test for categorical variables. Out of 51,886 blood or CSF cultures, 1,528 (2.9%) were positive for microorganisms of interest, and 211 (13.8%) were MDROs. The highest resistance proportions were observed in Carbapenems-Resistant Pseudomonas Aeruginosa/Pseudomonas Aeruginosa (CRPA/PA, 52.8%), followed by Methicilln-Resistant Staphylococcus Aureus/Staphylococcus Aureus (MRSA/SA, 36.7%), Carbapenem-Resistant Klebsiella Pneumoniae/Klebsiella Pneumoniae (CRKP/KP, 12.6%), and Vancomycin-Resistant Enterococcus (VRE)/Enterococcus (VRE/E, 11.5%). Significant reductions were recorded for MRSA/SA (43.5% in 2017 to 25.7% in 2023; p\u2009=\u20090.001) and CRPA/PA (85.0% to 47.1%; p\u2009<\u20090.001), while CRKP/KP and VRE/E showed no significant temporal trends. Neonatology and PICU showed higher odds for MRSA isolation (p\u2009<\u20090.001) compared to medical wards. Onco-hematology displayed an adjusted OR of 3.0 (95% CI: 1.2-7.7) for VRE. Year was independently associated with CRPA, with adjusted ORs of 0.03 and 0.14 in 2020 and 2021 (p\u2009<\u20090.01) compared to 2017. Understanding local AMR patterns remains essential for guiding empirical therapy across heterogeneous hospital settings.",

The stagnation of new antibiotic development underscores the urgent need for alternative therapeutics. This review summarizes recent advances in the application of bacteriophage endolysins against major MDR respiratory pathogens, including Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae. We focus on their mechanisms of action, synergistic effects with antibiotics, and efficacy against biofilms. Endolysins demonstrate potent and species-specific lytic activity against a broad spectrum of MDR bacteria. A key advantage is their low propensity for inducing resistance. Critically, when administered via optimized inhalation delivery systems, endolysins can achieve high local concentrations in the lungs - though this depends on factors such as the aerosol device, formulation properties and patient-related variables - effectively eradicating pathogens in animal models of pneumonia with minimal systemic toxicity. This direct pulmonary delivery approach bypasses many challenges associated with systemic administration and enhances therapeutic outcomes. Endolysins represent a promising paradigm shift in combating drug-resistant bacterial pulmonary infections. Their rapid lytic activity, synergy with conventional antibiotics, and suitability for inhalable formulation position them as a potent adjunct or alternative therapy. While challenges in stabilization and large-scale production remain, advancing inhalation delivery systems for endolysins holds immense potential to holds immense potential to revolutionize the treatment of recalcitrant respiratory infections.",

In this context, the progressive limitation of therapeutic options has led to the reintroduction of polymyxin antibiotics, such as colistin, into clinical practice as last-resort agents. However, the widespread use of colistin has been accompanied by an increasing incidence of resistance, among which heteroresistance has emerged as a significant challenge for both diagnosis and treatment. Heteroresistance is defined as the presence of subpopulations within a bacterial isolate that exhibit varying levels of susceptibility to a given antibiotic. In Acinetobacter baumannii, colistin heteroresistance may result in the selection and expansion of resistant subpopulations during therapy, contributing to clinical failure, persistent infections, and recurrence. Furthermore, the inability of routine antimicrobial susceptibility testing methods to reliably detect heteroresistance may lead to its underrecognition in clinical settings, potentially resulting in inappropriate therapeutic decisions. Current evidence indicates that the prevalence of colistin heteroresistance in A. baumannii varies geographically. The findings presented in this review highlight the importance of increasing awareness of the molecular basis and clinical implications of colistin heteroresistance in A. baumannii, and emphasize the need for improved diagnostic approaches and more effective treatment strategies for both microbiologists and clinicians.",

This study aimed to compare clinical and environmental S. saprophyticus strains isolated from a polluted coastal ecosystem in Brazil, assessing their virulence-associated traits, antimicrobial resistance, biofilm formation, and susceptibility to bacteriophages. Forty strains (20 clinical, 20 environmental) were characterized using GTG5-PCR, virulence gene screening, antibiotic susceptibility testing, biofilm assays, exposure to sub-inhibitory concentrations of ciprofloxacin, Tenebrio molitor infection model, and phage activity tests. Genetic fingerprinting and virulence gene profiles revealed a high degree of similarity between environmental and clinical isolates, indicating the presence of shared virulence-associated determinants. Environmental strains exhibited resistance to multiple antibiotics and showed biofilm formation and larval survival patterns comparable to those observed for clinical isolates. Exposure to sub-inhibitory concentrations of ciprofloxacin increased biofilm formation in several strains. Bacteriophage CSF, originally isolated from swine farm effluent, displayed lytic and antibiofilm activity against a substantial proportion of the isolates. These findings highlight the presence of clinically relevant traits among environmental S. saprophyticus strains and underscore the importance of continued microbiological surveillance in anthropized aquatic environments.",

With the aim of determining the possible role of specific residues in the bioactivity of this peptide, we studied a proline residue at position 9 and the C-terminal amidation of this peptide. Two inactivated variants were analyzed: Uy234-C, a non-amidated peptide, and Uy234-A, a P9A mutant. In addition to quantifying in detail the minimum inhibitory and bactericidal concentrations for each microorganism, membrane-damaging effects were assessed through bacterial cell viability assays with SYTO9/PI fluorophores. In addition, AFM, electroforming, and GUV microaspiration were used to determine the effects of each peptide in terms of permeabilization. Molecular dynamics (MD) simulations were also performed for the wild-type peptide and its P9A mutant. Only the native peptide Uy234 showed bacteriostatic and bactericidal activity, whereas the P9A mutant and non-amidated variant lost antimicrobial activity, demonstrating the essential role of the Pro-9 residue and C-terminal amidation in Uy234 bioactivity against both pathogens. SYTO9/PI assays in S. aureus infection showed membrane damage only with native Uy234, while AFM and GUV studies revealed membrane thinning, lateral expansion, and dose-dependent permeabilization of lipid bilayers. Our study provides clear evidence of a damaging effect on the membrane associated with the bioactivity of Uy234. This bioactivity is directly associated with the presence of residue P9 and the presence of C-terminal carboxyamidation. The mutant peptide P9A is unable to permeabilize GUVs, which is consistent with the persistence of a greater degree of structural order, according to MD simulations in the aqueous phase. This study provides a framework for the rational design of bactericidal peptides targeting multidrug-resistant bacteria.",

Pneumonia is the primary cause of sepsis. Animal models are important tools for studying the pathogenesis of sepsis and evaluating new treatment strategies. Previous animal models of sepsis lacked natural infection pathways, making it difficult to accurately reflect the clinical infection process. This study introduced a mouse sepsis immunosuppression model established by intranasal instillation of Klebsiella pneumoniae (KP) to simulate the natural respiratory infection pathway. After modeling with different concentrations of KP, the inflammation of the model was evaluated at 12 h for cytokine interleukin-6 (IL-6) levels, and organ damage was evaluated at 24 h for alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK), and blood urea nitrogen (BUN) levels. The survival rate of the model was analyzed after 7 days. The percentage of lymphocytes and white blood cells, the proportion of major histocompatibility complex class II (MHC-II) expression in monocytes, and the mean fluorescence intensity (MFI) of IL-10 and TGF-\u03b21 in CD4+ T cells were observed to evaluate the immune suppression in mice. After 7 days of modeling, a secondary infection was performed by intranasal instillation of Pseudomonas aeruginosa (PA). The bacterial load in bronchoalveolar lavage fluid (BALF) 24 h after secondary infection and the mortality rate within 14 days were assessed to further evaluate the model's immune suppression. Nasal instillation of high-concentration Klebsiella pneumoniae can effectively induce an immune suppression. Its purpose is to simulate sepsis induced by a natural respiratory infection pathway and to provide a standard model for sepsis research in animals.",

L5.\nAbstract: A novel bacterium with heterotrophic nitrification-aerobic denitrification (HN-AD) capability, designated Pseudomonas sp. L5, was isolated from the activated sludge of an aerobic denitrification reactor in our laboratory and subsequently identified. This strain can efficiently conduct nitrogen metabolism using NH4 +-N, NO3 --N and NO2 --N as nitrogen sources. Single-factor experiments combined with response surface methodology (RSM) were used to optimize the culture conditions of strain L5. The predicted optimal conditions for growth and nitrogen removal were a C/N ratio of 31.29, sodium acetate as the carbon source, a temperature of 31.18\u00b0C, and an initial pH of 7.25. Notably, even under mildly alkaline conditions (pH\u20099.0), the strain maintained high aerobic denitrification efficiency, with a NO3 --N removal rate of 86.236%. The nitrogen metabolism pathway of strain L5 was elucidated through a combined analysis of the expression of key HN-AD genes and enzyme activities. The denitrification capacity of strain L5 under alkaline conditions provides a theoretical basis and technical support for the application of aerobic denitrifying bacteria in high-pH wastewater treatment.",

The present study aimed to investigate the antimicrobial and anti-biofilm properties of dermcidin-derived peptides against clinical isolates of these bacteria. Clinical isolates of methicillin-susceptible and methicillin-resistant S. aureus (MSSA and MRSA), as well as carbapenem-susceptible and carbapenem-resistant P. aeruginosa (CSPA and CRPA), were examined for their susceptibility to dermcidin-derived peptides (DCD-1\u00a0L, SSL-23, and SSL-25). The in vitro inhibitory activity of the peptides on bacterial adhesion and biofilm formation was evaluated at sub-MIC levels, while their biofilm-disrupting potential was assessed on mature biofilms. Furthermore, the expression of key biofilm-associated and quorum-sensing genes was quantified using qRT-PCR following peptide exposure. Dermcidin-derived peptides markedly inhibited bacterial attachment and biofilm formation at sub-inhibitory concentrations (1/2, 1/4, and 1/8 MIC). In addition, they exhibited strong biofilm eradication activity at higher concentrations (8\u00d7-64\u00d7 MIC). Gene expression analysis revealed significant down-regulation of adhesion- and quorum-sensing-related genes in both S. aureus and P. aeruginosa after treatment. The results suggest that dermcidin-derived peptides, regardless of their net charge, possess potent inhibitory effects on bacterial attachment and biofilm development. These findings highlight their potential as promising therapeutic agents for the prevention and control of biofilm-associated infections.",

Here, we report the rational design and validation of a non\u2011natural shortcut pathway enabling de novo biosynthesis of 3\u2011HAA and QA in Escherichia coli. The pathway begins from anthranilic acid (AA), a chorismate\u2011derived intermediate that can be efficiently overproduced. Regioselective 3-hydroxylation of AA was achieved using an FAD-dependent monooxygenase HpaH from Geobacillus thermodenitrificans, supported by a dedicated FAD reductase (GTNG_3158) essential for efficient cofactor regeneration. The resulting 3\u2011HAA was subsequently converted to QA through oxidative ring cleavage by NbaC from Pseudomonas fluorescens, followed by spontaneous cyclization. Through enzyme expression tuning, precursor availability enhancement, and fermentation optimization, the engineered strains produced 2.17\u00a0g/L 3\u2011HAA and 2.04\u00a0g/L QA from glucose in shake flasks, representing the highest reported microbial 3\u2011HAA titer and demonstrating the efficient extension of the artificial pathway to QA production. This work establishes a concise and productive biosynthetic strategy, enabling sustainable and high\u2011level microbial production of 3-HAA\u2011derived compounds.",

Several novel methods have been introduced that enable direct antimicrobial susceptibility testing (AST) from positive blood cultures. This study aimed to assess the analytical performance of the agar diffusion-based EUCAST rapid AST (RAST) method and the automated QuickMIC system using a challenging collection of highly resistant Gram-negative organisms. One hundred one Gram-negative bacteria (Escherichia coli, n = 24; Klebsiella pneumoniae, n = 22; Acinetobacter baumannii, n = 30; and Pseudomonas aeruginosa, n = 25) were spiked into blood cultures and processed according to the respective AST protocols. Broth microdilution (BMD) was performed as the reference method. Time to result (TTR), categorical agreement (CA), and essential agreement (EA) with BMD were evaluated. Boruta analysis was applied to identify genetic determinants associated with AST errors. Overall TTR for QuickMIC was 3 h 44 min with a CA of 86.2% and an EA of 92.3% for Enterobacteriaceae and 97.0% for non-fermenters. Overall CA of RAST ranged from 90.7% to 93.7% across reading time points. Overall, very major discrepancy rates were low (QuickMIC, n = 0.7%, and RAST, n = 0.1%). Presence of NDM-5 and KPC was most frequently associated with errors for QuickMIC and EUCAST RAST, respectively. Both rapid AST approaches yielded rapid and robust results in this diverse and highly resistant bacterial study population. These findings underscore the potential of rapid AST methods to facilitate timely optimization of antimicrobial therapy in bloodstream infections, even in the context of extensively drug-resistant pathogens.IMPORTANCEAccurate antimicrobial susceptibility testing (AST) is essential for stewardship and effective therapy, especially as rising antimicrobial resistance increases the risk of empiric treatment failure. Traditional AST methods are limited by slow turnaround times, creating a need for rapid alternatives. This study evaluated the diagnostic accuracy of two rapid AST (RAST) methods-EUCAST RAST and QuickMIC-using 101 genetically characterized, carbapenem-resistant Enterobacterales, Pseudomonas aeruginosa, and Acinetobacter baumannii tested directly from positive blood cultures. Broth microdilution served as the reference. Both rapid assays provided results within 3.5-6 h and demonstrated high categorical and essential agreement with few very major discrepancies. Incorrect results were more common in isolates harboring NDM-5 and KPC carbapenemases. Overall, the findings support EUCAST RAST and QuickMIC as reliable tools for challenging resistant pathogens and highlight their potential to enable earlier detection of carbapenem-resistant phenotypes and more timely initiation of appropriate, last-resort antimicrobial therapy.",

Multidrug resistance (MDR) and virulence of P. aeruginosa has been a major reason linked to the high rates of mortality in both developed and non-developed countries. The study focused specifically on main structural outer membrane proteins mainly oprI and oprL due to their significant role on both virulence and MDR by assessing their MDR from the isolates collected from various healthcare settings in Lahore, Pakistan. A total of 65 isolated were collected from different tertiary care hospitals of Lahore, Punjab. All isolates were identified and characterized using conventional methods. MDR patterns were assessed through disk diffusion method in accordance with CLSI 2024 guidelines. Detection of virulence genes (oprI and oprL) was performed using PCR amplification. Statistical and in silico analysis was performed to analyse the prevalence of P. aeruginosa and identification of potential vaccine targets provide alternative treatment strategies against infections caused by it. Out of all 65 isolates, total of 52 isolates was reportedly positive with P. aeruginosa and showed 100% resistance to \u03b2-lactams with high susceptibility to cephalosporins and fluoroquinolones. Multidrug resistance was reported in 70% isolates of P. aeruginosa. All isolates (100%) harbored the oprL gene while the oprI gene was detected in 85.5% of isolates. In silico characterization revealed strong binding B and T cell epitopes with 100% conservancy as potential multi-epitope candidates that warrant further in vivo and in vitro validation to overcome deadly infections caused by P. aeruginosa. In conclusion, MDR and virulence gene characterization by both molecular and computational methods will aid in developing multi-epitope vaccine candidate that can be tested in vitro and in vivo to overcome MDR and rising mortality rates in Pakistan.",

To date, there are no well-established animal models for bronchiectasis. Thus, our aim was to develop a novel animal model that accurately recapitulates bronchiectasis-like pathologies. To address this question, clinical strains of chronic Pseudomonas aeruginosa (CPA) were embedded in agar beads in\u00a0vitro; then CPA-loaded agar beads and papain were repeatedly instilled intratracheally in female C57BL/6\u2009J mice. Experimental assessments included micro-computed tomography (micro-CT) imaging, histological analysis, immune cell infiltration, cytokines, and lung function parameter measurements to evaluate structural damage, immune responses, and lung function impairments in the mouse model. In this mouse model, we observed that lung micro-CT imaging revealed significant bronchiectasis, with visible airways in the periphery, cylindrical airway expansion, and an airway-to-artery ratio >\u20091. Histopathology highlighted immune cell infiltration around the trachea, including lymphocytes, neutrophils, and monocytes, along with Periodic acid-Schiff staining-positive hypermucinous secretion. Compared to controls, the bronchiectasis group exhibited elevated pro-inflammatory cytokines in bronchoalveolar lavage fluid and worse lung function. Our study presented a novel mouse model that better replicated the bronchiectasis-like phenotype than the CPA airway infection model, showing the advantages of the \"CPA-loaded agar beads and papain\"-driven approach in optimizing the disease models. The model mimicked the progression of bronchiectasis closely and could be used for studies on disease pathogenesis as well as the evaluation of novel therapies in the near future.",

Until now no licensed PA vaccine exists and multi-dose schedules are difficult to complete in emergency settings, thus a single-dose, dual-indication vaccine that provides rapid and durable protection is urgently needed. Here, we engineered and characterized a lumazine synthase (LS) nanoparticle vaccine (rePO-TTFC@LS) that co-displays a PA antigen (rePO; PcrV-OprI fusion) and tetanus toxin fragment C (TTFC). In BALB/c mice, rePO-TTFC@LS enhanced antigen uptake and dendritic-cell activation relative to soluble antigens. After a single intramuscular immunization, rePO-TTFC@LS elicited rapid, high anti-rePO and anti-TTFC IgG responses together with increased IFN-\u03b3/IL-4/IL-17A-secreting splenocytes. Vaccination reduced lung bacterial burden and pulmonary IL-1\u03b2/IL-6 and improved survival and clinical outcomes in an acute PA pneumonia model, which provided complete protection against lethal tetanus toxin challenge, and decreased PA colonization with improved survival in a femoral fracture-implant co-infection model. Elevated antibody titers and dual protection persisted to 28 weeks after one dose, and biosafety assessments showed no meaningful hemolysis or cytotoxicity and no abnormalities in hematology/serum biochemistry or multiorgan histopathology. Collectively, these results support rePO-TTFC@LS as a single-dose, durable dual-indication nanoparticle vaccine and highlight a modular strategy for combination vaccines suited to mixed-exposure emergency scenarios.",
        "42383755": "ID: 42383755\nTitle: The gac system integrates physical and chemical cues to promote plant root attachment.\nAbstract: Plants host complex communities of microbes that are attached to root surfaces. While many studies have sampled mutant populations after prolonged incubation on roots to identify bacterial genes that enable long-term colonization, the molecular mechanisms governing the early stages of root attachment remain less understood. Here, we developed an in vitro root culture system that enables controlled and scalable investigation of bacterial attachment to root tissue. We used this platform to perform a genome-wide screen for root attachment determinants in the plant-associated bacterium Pseudomonas protegens Pf-5. Our results reveal that the gacSA two-component system functions as a sensory integration hub for coordinating early root attachment. Mutations that disrupt gacS or gacA cause severe root attachment defects despite having no effect on abiotic surface attachment in standard biofilm assays. Mutation of flagellar assembly genes enhances root attachment by mimicking surface contact and activating the gac system. In parallel, chemical cues released by roots stimulate surface attachment in a gac-dependent manner. By integrating these signals, the gac system activates cyclic-di-GMP-mediated attachment programs that drive the transition from planktonic to sessile behavior required for root association. We build on this model to show that manipulating flagellar surface-sensing sustains the attachment of Pf-5 in the presence of a synthetic bacterial community, suggesting a strategy to improve the attachment of beneficial microbes on crops. These findings establish a mechanistic framework linking surface sensing, global regulation, and root attachment in a beneficial rhizobacterium.IMPORTANCEPlant roots are covered with diverse microbes that strongly influence plant health. Growing in association with roots has many benefits, but how bacteria attach to root tissue remains poorly understood. We developed a system to study how the plant-associated bacterium Pseudomonas protegens Pf-5 attaches to roots. We found that physical contact with the root surface and chemical cues released by roots both enhance attachment to roots. A sensory system called gacSA is responsible for integrating physical and chemical cues to activate a root attachment program. Variant bacteria that prematurely activate the gac system attach more effectively even in the presence of other bacteria on roots, suggesting that the root attachment pathway we characterized could serve as a strategy to use beneficial bacteria in agriculture.",

Its distribution and evolutionary significance in Acinetobacter baumannii is not fully understood. Here, we investigated the ST19 lineage, revealing a near-complete absence of the T6SS across 159 genomes from diverse geographic and clinical origins. Comparative genomic analysis showed that the T6SS locus in ST19 is frequently disrupted, with some isolates harboring insertions of mobile genetic elements, while in others, the region is fragmented or unresolved. To assess whether T6SS loss is associated with broader genomic changes, we analyzed 8,218 publicly available A. baumannii genomes. Interestingly, T6SS-negative genomes did not exhibit increased acquisition of accessory genetic material. Instead, they carried fewer antimicrobial resistance genes (8.06 vs 10.56 per genome), fewer virulence genes (101.8 vs 132.5 per genome), and comparable plasmid replicon content relative to T6SS-positive genomes. However, T6SS-negative genomes exhibited a higher number of insertion sequences (IS) per genome compared to T6SS-positive genomes (mean ~12.3 vs ~9.0 IS elements per genome, respectively). Ancestral state reconstruction of the frmRAB and the putative chlorite dismutase genes within ST19 revealed identical distribution patterns and strong phylogenetic conservation, with 7 inferred state transitions indicating limited evidence for independent gain or loss events. Our results suggest that T6SS loss represents a lineage-specific evolutionary trajectory characterized by loss of the T6SS locus and reduced accessory genome, suggesting an alternative ecological strategy.",

Here, we engineered dimeric SHKs based on Pseudomonas putida short light-oxygen-voltage (LOV) proteins, determined their crystal structures, and investigated their signaling mechanisms. Regardless of illumination, the structures adopted a light-state like LOV-LOV dimer with symmetric/straight kinase modules. In contrast, small-angle x-ray scattering together with functional assays revealed pronounced light-dependent rearrangements in solution and allowed the assignment of the kinase-ON dark state to an asymmetric/kinked conformation, whereas the light state adopts a symmetric/straight structure. Comparative analyses of natural and engineered SHKs identified conserved motifs linking light-induced LOV domain rotation to kinase activity. The findings highlight the central role of dimer asymmetry and flexibility in SHK signaling, thereby not least informing the engineering of new light-responsive signaling systems.",

Understanding the bacteriological profile and antibiotic sensitivity is essential for guiding therapy and curbing inappropriate antibiotic use. Therefore, this study aimed to determine the bacteriological profile of burn wounds and assess antimicrobial sensitivity on the 1st, 5th, and 10th post-burn days in a tertiary burn care center. A prospective observational study was conducted at National Institute of Burn and Plastic Surgery (NIBPS), Dhaka, Bangladesh, from July 2022 to December 2023. A total of 110 patients with burns involving 10-50% of total body surface area were enrolled and followed longitudinally. Wound swabs were collected from the same patients on the first, fifth, and 10th post-burn days to assess the early, intermediate, and later phases of bacterial colonization and antimicrobial susceptibility changes over time. Isolates were identified by standard microbiological techniques, and antibiotic susceptibility testing was performed using the CLSI disc diffusion method. Children under 10 years constituted the largest proportion of cases (43.6%). Flame burns predominated (50%), with the trunk most commonly affected (73.6%). Bacterial growth increased from 36.4% on day 1 to 86.4% by day 5 and remained high on day 10. Gram-negative organisms predominated throughout the study period, with Pseudomonas aeruginosa being the most frequent isolate. None of the tested antibiotics demonstrated consistently high susceptibility. Colistin demonstrated comparatively higher susceptibility than other tested antibiotics, although susceptibility rates remained suboptimal. Burn wounds showed rapid colonization predominantly by gram-negative organisms, particularly Pseudomonas aeruginosa, with low antibiotic susceptibility across several commonly used agents. The findings highlight the potential importance of continuous microbiological surveillance, burn unit-specific antibiograms, antimicrobial stewardship, and rational antibiotic use in burn care settings.",

Its remarkable ability to survive in adverse environments, persist on medical devices, and rapidly acquire multidrug resistance has made it a critical global healthcare concern. This review aims to provide a comprehensive overview of the epidemiology, risk factors, antimicrobial resistance mechanisms, and pathogenicity of CRAB, with a special emphasis on the role of biofilm formation. CRAB infections are strongly associated with prolonged hospitalization, mechanical ventilation, previous antibiotic exposure, and invasive procedures. The organism exhibits multiple resistance mechanisms, including carbapenemase production, efflux pumps, porin modifications, and horizontal gene transfer, which significantly limit therapeutic options. A key virulence factor is its capacity to form biofilms on biotic and abiotic surfaces, enhancing bacterial survival, immune evasion, and resistance to antimicrobial agents. Biofilm-associated infections are often chronic, recurrent, and difficult to eradicate, particularly in device-related infections. The interplay between biofilm formation and antimicrobial resistance further complicates treatment outcomes. Current management strategies rely on last-resort antibiotics, combination therapy, antimicrobial stewardship, and strict infection control practices, while emerging therapies targeting biofilms offer promising alternatives. Understanding these complex mechanisms is essential for developing effective therapeutic and preventive strategies against CRAB infections.",

Against Phytopathogens Fusarium oxysporum and Rhizoctonia solani.\nAbstract: Bioactive compounds from endophytic bacteria contribute significantly to drug discovery and plant defense. Medicinal plants, such as Lawsonia inermis L., serve as a rich source of microbial endophytes. To isolate and characterise endophytic bacteria from L. inermis leaves and evaluate their bioactive metabolites for antimicrobial and biocontrol potential. Endophytic bacteria were isolated from surface-sterilised leaves of L. inermis. Morphological and molecular identification, including 16S rRNA gene sequencing and phylogenetic analysis, identified the isolates as Bacillus subtilis, Pseudomonas mosselii, and Sphingomonas aquatilis. Metabolite profiling was performed using Fourier transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry (GC-MS). Antifungal activity was tested against Fusarium oxysporum f. sp. lycopersici and Rhizoctonia solani using dual-culture assays. The endophytes demonstrated significant antagonistic activity, inhibiting the growth of fungal mycelia. FTIR spectra indicated the presence of carboxylic, ester, ketone, and alkane functional groups. GC-MS analysis of active fractions revealed several known antimicrobial and pharmaceutical compounds, supporting the observed bioactivity. Endophytic bacteria from L. inermis produce bioactive secondary metabolites with potent antifungal activity.

Bacteriocins, as highly promising antibacterial candidates, have garnered considerable attention in the scientific community. In this study, a novel bacteriocin, designated Pacin, was successfully purified from the fermentation broth of Pseudomonas strain 166. Pacin exhibited potent antibacterial activity against MRSA, with minimum inhibitory concentration (MIC) of 0.25 \u00b5g/mL. At concentrations up to 512 \u00b5g/mL, Pacin showed no significant cytotoxicity toward Vero or F81 cells and induced negligible hemolysis of rabbit red blood cells, with a hemolytic rate below 0.04%. In a murine model of MRSA-infected wounds, Pacin significantly promoted wound healing. In a peritonitis-sepsis model, mice treated with Pacin displayed no organ abnormalities and a marked reduction in bacterial burden. Further analyses, including cell membrane integrity assays, cell wall integrity assessments, scanning electron microscopy, and transmission electron microscopy, demonstrated that Pacin exerts its antibacterial effect by disrupting the bacterial cell membrane and cell wall structures, thereby inhibiting bacterial survival. Collectively, these findings establish Pacin as a highly effective antibiotic alternative for combating MRSA infections, with substantial potential for clinical application. This study introduces Pacin, a novel bacteriocin isolated from Pseudomonas strain 166, as a potent therapeutic agent against MRSA. With the global rise of antibiotic resistance threatening public health, there is an urgent need for safe and effective alternatives to conventional drugs. Pacin demonstrates exceptional activity by effectively killing MRSA through membrane and cell wall disruption while showing no toxicity to mammalian cells or zebrafish embryos. Its stability under varying environmental conditions and shows efficacy in treating severe skin infections and sepsis in animal models highlight its clinical potential. These findings position Pacin as a promising next-generation antimicrobial agent capable of addressing critical gaps in current treatment strategies for life-threatening resistant infections.",

The high intrinsic resistance of NFGNB to antimicrobial compounds makes treatment of BSI difficult and expensive. This study aimed to determine the prevalence of NFGNB and the antimicrobial susceptibility pattern of the isolates. A total of 1230 blood culture samples were received in the department of microbiology during the study period of 3 months, which were processed by standard microbiological procedures. Antimicrobial susceptibility tests were performed using Clinical and Laboratory Standards Institute (CLSI) guidelines. Out of 255 (20.73%) positive blood culture samples, 105 (8.5%) Gram-negative bacilli were isolated, of which 41 (3.33%) NFGNB were identified. The most common isolate identified is Pseudomonas aeruginosa (21), followed by Acinetobacter spp. (20). A higher percentage of antibiotic resistance was seen for Acinetobacte r spp. and even higher antibiotics like ceftazidime (87.5%) and gentamicin (92.5%).

        "42390567": "ID: 42390567\nTitle: Disrupting virulence: in silico discovery of MexL inhibitors to block pyocyanin biosynthesis in Pseudomonas aeruginosa.\nAbstract: Pseudomonas aeruginosa is an opportunistic pathogen known for its intrinsic antibiotic resistance and ability to form biofilms, primarily regulated by the redox-active compound, pyocyanin. The transcriptional activator (Multidrug efflux regulator L) MexL plays a crucial role in the biosynthesis of pyocyanin by upregulating key genes such as phz1, phz2, and phzM. Targeting MexL may serve as a novel anti-virulence strategy by suppressing pyocyanin production and attenuating pathogenicity of P. aeruginosa. This study aimed to identify potential inhibitors of MexL using in silico approaches to disrupt its regulatory function and reduce pyocyanin synthesis. The findings suggest that the selected compounds could serve as effective inhibitors of MexL, offering a promising strategy to suppress pyocyanin biosynthesis and reduce P. aeruginosa virulence. For this purpose, molecular docking was conducted between the binding pocket of the MexL protein and compounds selected based on pharmacokinetic properties from the FooDB, NPASS, and LOTUS databases. Furthermore, molecular dynamics simulations were performed on the selected MexL-ligand complexes to evaluate the stability of the protein-ligand complex within a simulated solvated environment under defined conditions. The virtual screening by molecular docking identified four top-scoring ligands FDB000380, LTS0012415, and NPC253096 and ZINC14780782 with binding energies of -8.6, -7.5, -7.1, and -8.8\u00a0kcal/mol respectively, showing strong affinities toward the MexL binding pocket. These ligands demonstrated key molecular interactions with residues critical for regulatory function of MexL protein. Molecular dynamics simulations (300\u00a0ns) of the three lead MexL-ligand complexes (FDB000380, LTS0012415, and NPC253096) revealed exceptional structural stability, with low backbone RMSD values (0.240-0.309\u00a0nm), minimal residue fluctuations, stable radius of gyration, and consistent solvent-accessible surface area profiles. Persistent protein-ligand hydrogen bond networks (occupancy 72.1-100%) confirmed stable polar interactions throughout the trajectories. MM-GBSA and MM-PBSA binding free energy calculations demonstrated superior affinities over the endogenous ligand pyocyanin (\u0394G\u2009=\u2009\u2009-\u200915.30 to\u2009-\u200921.75\u00a0kcal/mol versus\u2009-\u200912.57\u00a0kcal/mol). Principal component analysis further revealed restricted conformational dynamics and compound-specific free energy landscapes, collectively supporting these three compounds as thermodynamically stable lead inhibitors of MexL-mediated pyocyanin biosynthesis in Pseudomonas aeruginosa.",

Many bacteriophages synthesize complex modifications (i.e. hypermodifications) to the nucleobases of their virion DNA in order to circumvent the endonuclease-based defenses of their hosts. To date, most hypermodified pyrimidines in viruses are synthesized via group transfer to a pre-existing hydroxyl moiety in DNA during the later stages of lytic development leading up to packaging of the viral chromosome into the capsid. Typically, these occur at hydroxymethylcytosine or hydroxymethyluracil. We find mono- and poly-arabinosylated cytidines completely replacing canonical cytidine in the native DNA of the Escherichia phage RB69 and Acinetobacter baumannii phage DLP3. In both cases, an arabinosyl moiety is connected directly to the pyrimidine through an ether linkage, with the bridging oxygen originating from 5-hydroxycytosine (5hoC) in DNA. The 5hoC is synthesized as a mononucleotide by a virally encoded thymidylate synthase homolog. We find diverse virally encoded thymidylate synthase homologs, including the Rhizobium phage RL38J1, are capable of producing 5hoC, suggesting this base modification is a starting point for glycodiverse cytosine derivatives. Characterizing these cytosine derivatives adds to our understanding of viral anti-defense mechanisms.",

This work explored the role of lysine succinylation (Ksucc) in regulating CsrA activity, a global post-transcriptional regulator. NanoHPLC-MS/MS identified Lys38 (K38), a highly conserved residue within the CsrA RNA-binding interface, as a functional succinylation site. Site-directed mutagenesis revealed that K38 succinylation significantly inhibits biofilm formation by reducing c-di-GMP levels, exopolysaccharide production, and surface hydrophobicity, while enhancing flagellar-mediated motility. Colonization assays on foods, contact surfaces, and the rhizosphere confirmed that CsrA succinylation restricts biofilm formation across diverse ecological niches. These results identify K38 succinylation of CsrA as a regulatory modification that modulates the transition between motile and sessile lifestyles in P. fluorescens PF08. These findings expand the understanding of post-translational control of biofilm formation in this ecologically versatile bacterium relevant to food spoilage and agricultural environments.",

This study investigated the influences of CO2 on both type and wild-type P. fragi growth and cell membrane characteristics during the chilled storage of HiOx-MAP (TMAP\u00a0=\u00a050% O2/40% CO2/10% N2; CMAP\u00a0=\u00a050% O2/50% N2). Compared to CMAP, TMAP significantly reduced P. fragi counts by limiting its motility and disturbing cell membrane structure, composition and function, without causing membrane rupture. CO2 weakened P. fragi membrane function by inducing phospholipid perturbations, but promoted intracellular adenosine triphosphate production as a stress response. Although both packaged P. fragi membrane fluidity and permeability first decreased then increased during storage, a higher (P\u00a0<\u00a00.05) membrane fluidity and permeability was observed in TMAP P. fragi than in CMAP P. fragi over time, indicating P. fragi gradually adapted to a high-CO2 environment. The CO2-elevated ratio of unsaturated to saturated fatty acids significantly increased P. fragi membrane fluidity, and thus enhanced its membrane permeability. This study offers a new mechanistic basis for the CO2-bacteriostatic action in meat preservation targeted at bacterial cell membranes.",

While the control of such pathogens typically relies on synthetic chemical fungicides preharvest, microbial biocontrol agents are a sustainable and promising alternative postharvest. Bacillus velezensis SH1 and SH2 and Pseudomonas azotoformans SH3 were previously isolated from disease-suppressive compost tea. To evaluate their effectiveness against tomato pathogens, the bacteria, their cell-free culture filtrates and precipitated subfractions were tested against mycelial growth in vitro. Suppressive effects were also examined against disease development on tomato fruit. From bacterial precipitates, lipopeptides were further identified and quantified. Results showed that all bacteria controlled growth of the three fungi, with P. azotoformans SH3 generally being the most effective. However, in vivo disease lesion suppression varied according to pathogen and tomato cultivar. In cell-free culture filtrate assays, mycelial inhibition was observed from all bacteria against B. cinerea, whereas mainly B. velezensis SH1 inhibited A. solani and A. alternata growth. For bacterial precipitates, B. velezensis SH1 was the best treatment overall, while P. azotoformans SH3 precipitates showed no inhibition. Both B. velezensis strains were confirmed to produce fengycins, iturins and surfactins. Fengycins seemed to play the most important role in the observed activity of the Bacillus lipopeptides. Results suggest that antifungal activity by the bacterial strains is imparted through the release of antifungal compounds, although the role of the produced compounds was variable.",

In P. aeruginosa, the TonB-dependent transporters (TBDT) FpvA and FpvB mediate PVD-dependent iron acquisition. PVDs have emerged as promising vectors for antibiotics in antibacterial Trojan horse strategies. However, the uptake of PVD-antibiotic conjugates by FpvA and FpvB remains poorly characterized. Here, we report the semisynthesis of a PVD-oxazolidine conjugate used as a molecular tool to investigate how P. aeruginosa accesses iron via these TBDTs in the presence of two native PVDs and their corresponding antibiotic conjugates. Growth assays demonstrate that P. aeruginosa can access iron chelated by PVDs through both FpvA and FpvB. In contrast, although both antibiotic conjugates provide iron to the strain via FpvA, only one does so via FpvB, indicating differential receptor recognition. Docking analyses reveal that native PVDs adopt similar binding modes within both FpvA and FpvB. However, FpvB-previously described as a broadly selective transporter-exhibits selective restriction toward PVD-antibiotic conjugates. Our results provide insights for the design of PVD-antibiotic conjugates and emphasize the critical role of the conjugation site on PVD in ensuring efficient transporter-mediated uptake.",

However, differences in antibacterial spectra and resistance mechanisms among clinically important Gram-negative bacteria (GNB) between these two agents remain incompletely understood. English-language publications indexed in PubMed (1990-2026), records retrieved from Google Scholar, and the 2018-2024 Antimicrobial Testing Leadership and Surveillance database were extensively reviewed to assess their potential clinical utility. ATM-AVI demonstrates broad activity against KPC-, MBL-, and OXA-48/181-like-producing CRE. However, ATM-AVI non-susceptibility occurs in Escherichia coli and Providencia rettgeri isolates harboring blaCMY, penicillin-binding protein 3 (PBP3) modifications, and porin dysfunction or acrA efflux overexpression. In contrast, CFDC activity is primarily compromised by NDM production, reduced expression of iron transporters, and PBP3 alterations. Significant regional variation in CFDC susceptibility among MBL-producing CRE isolates collected in Asia and North America/Europe has been observed. Based on limited pooled real-world treatment experience, CFDC shows moderate efficacy (73%) for the treatment of infections caused by MBL-producing CRE. Both antibiotics also show potential in vitro activity against ceftazidime-avibactam-resistant, non-carbapenemase-producing CRE. Notably, CFDC exhibits excellent in vitro activity against contemporary CR-Pseudomonas aeruginosa, most CR-Acinetobacter baumannii harboring blaOXA-23/24/58 genes, Elizabethkingia anophelis, Stenotrophomonas maltophilia, Burkholderia cepacia, and Burkholderia pseudomallei. Nevertheless, CFDC heteroresistance is most prevalent among CR-A. baumannii isolates. Continued assessment of clinical treatment experience with these two antibiotics against MBL-producing CRE and important non-fermenting GNB is warranted to accumulate further evidence regarding their therapeutic roles.",

We conducted a retrospective cohort study of 377 adult patients with culture-confirmed invasive gram-negative infection acquired\u2009\u2265\u200948\u00a0h after admission to King Abdulaziz Medical City (KAMC), Jeddah, Saudi Arabia (2020-2024). Demographics, comorbidities, infection type, microbiology, susceptibility, complications, and outcomes were analyzed using chi-square/Fisher's exact tests and t-tests/Mann-Whitney U tests; multivariable logistic regression was used to identify independent predictors of multidrug-resistant (MDR) infection and in-hospital mortality. Infection types were classified according to U.S. Centers for Disease Control and Prevention / National Healthcare Safety Network (CDC/NHSN) surveillance definitions. Mean age was 64.6\u2009\u00b1\u200917.7 years (59.4% male). Hypertension (61.0%), diabetes (54.6%), and cardiovascular disease (40.8%) were the commonest comorbidities. Pneumonia predominated (47.1%), followed by bloodstream infection (33.0%), surgical-site infection (15.7%), and ventilator-associated pneumonia (9.6%). Klebsiella pneumoniae (41.9%), Pseudomonas aeruginosa (34.0%), and Escherichia coli (15.4%) were the predominant pathogens. Resistance was highest for ciprofloxacin (44.4%), ceftazidime (40.2%), and cefepime (39.9%), and 34.3% for meropenem. Overall morbidity was 68.6% and mortality 39.9%. Mortality was significantly higher in patients with cardiovascular disease (48.8% vs. 34.3%, p\u2009=\u20090.011), hypertension (45.4% vs. 31.5%, p\u2009=\u20090.015), and COPD (100.0% vs. 39.2%, p\u2009=\u20090.025). Diabetes was strongly associated with multidrug-resistant infection (OR 3.60, 95% CI 1.44-9.04; p\u2009=\u20090.004) and remained an independent predictor in multivariable logistic regression adjusting for age, sex, cardiovascular disease, and pneumonia (adjusted OR 2.82, 95% CI 1.11-7.17). HA-GNB infections at this Saudi tertiary center are dominated by K. pneumoniae and P. aeruginosa, carry a roughly two-in-five case fatality, and show worrying resistance to commonly used empirical agents. Within the constraints of a single-center, retrospective design, these findings support local antibiogram-informed review of empirical protocols, continued antimicrobial stewardship, and heightened infection-control attention to high-risk subgroups, particularly patients with diabetes and cardiopulmonary comorbidities; confirmation in prospective, multi-center studies is warranted.",

Disruption of epithelial integrity, microbiome imbalance, and immune dysregulation have all been linked to the translocation of multidrug-resistant (MDR) organisms from intestinal colonization to invasive infection. However, whether these associations reflect true causal mechanisms remains uncertain, and available human evidence has not been comprehensively synthesized using current methodological standards. To systematically evaluate human evidence examining the relationship between intestinal barrier dysfunction, microbial colonization, and subsequent MDR infection in adult critical illness, with particular attention to study quality, heterogeneity, and potential confounding factors. This systematic review was conducted in accordance with PRISMA guidelines. A structured literature search was performed in PubMed, EMBASE, and the Cochrane Library (2000-2025) using predefined Boolean combinations and Medical Subject Headings. Prospective and retrospective cohort studies involving intensive care units (ICU) adults were included if they evaluated intestinal colonization, biomarkers of barrier dysfunction (citrulline and intestinal fatty acid-binding protein), microbiome alterations, or endotoxemia. Study selection and data extraction were undertaken independently by two reviewers, with disagreements resolved through discussion. Risk of bias was assessed using the Newcastle-Ottawa Scale and ROBINS-I tool. Owing to methodological and clinical heterogeneity, findings were synthesized using a structured narrative approach rather than meta-analysis. Across the included studies, intestinal colonization with carbapenem-resistant Enterobacteriaceae, carbapenem-resistant Klebsiella pneumoniae, Acinetobacter baumannii, and vancomycin-resistant Enterococcus was consistently associated with an increased risk of subsequent bloodstream infection. However, progression rates varied considerably across cohorts, likely reflecting differences in patient characteristics, antimicrobial exposure, and ICU practices rather than a consistent effect size. Biomarker studies showed reduced citrulline levels and elevated intestinal fatty acid-binding protein concentrations in patients with gastrointestinal dysfunction; however, these markers indicate enterocyte injury rather than directly measuring intestinal permeability or bacterial translocation. Microbiome analyses demonstrated reduced diversity and impaired colonization resistance, although the extent and timing of these changes were not uniform across studies. Taken together, the evidence supports a biologically plausible link between epithelial injury, dysbiosis, and infection risk, but does not establish a direct causal relationship, largely due to the observational design of available studies and the influence of confounding factors such as illness severity, antimicrobial exposure, and ICU environment. Gut barrier dysfunction appears to contribute to the pathogenesis of MDR infection in critically ill adults; however, current evidence supports association rather than causation. Early recognition of intestinal colonization and strategies aimed at preserving mucosal integrity may offer potential clinical benefit, although their effectiveness requires confirmation in well-designed prospective and interventional studies.",

Here, we present a ramanome-based phage susceptibility test (RPST), a phenotypic platform that captures infection-induced remodeling of bacterial macromolecular composition to unify these diagnostic requirements within a single workflow. RPST integrates four Raman biomarkers into a Composite Infection Index (CII), enabling rapid and lysis-independent discrimination between susceptible and resistant bacterial populations within ~1\u2009h, with 96.0% categorical concordance (24/25) to plaque assays. As a continuous population-level metric, CII quantifies the proportion of infected cells, allowing quantitative ranking of phage potency against shared hosts. By resolving CII trajectories across the MOI and time, RPST further determines the minimal effective MOI, which is the lowest phage-to-bacterium ratio sustaining self-propagating infection, thereby defining the lower boundary for therapeutic feasibility. Together, these capabilities transform PST from static compatibility assays into a dynamic and quantitative framework that bridges in vitro infectivity assessment and infection dynamics relevant to phage therapy.",

Tetrasodium EDTA (tEDTA) is one of the new antimicrobial compounds that have been shown to have good antibacterial and antibiofilm efficacy against P. aeruginosa. Due to the diversity and highly drug-tolerant nature of P. aeruginosa biofilms in different infection environments, it is important to carry out pre-clinical testing of new antibiofilm agents against this pathogen in media and models that accurately mimic diverse infection environments. In this study, we used different high-validity media and biofilm models that mimic chronic wounds, endotracheal tubes and cystic fibrosis lung infections to assess the efficacy of tEDTA against P. aeruginosa biofilms. We report that different infection environments influence the susceptibility of both planktonic and biofilm forms of P. aeruginosa to tEDTA. The highest tolerance to tEDTA was observed in the media and biofilm model that mimics the endotracheal tube environment. In conclusion, we show that although different infection environments influence the efficacy of tEDTA against P. aeruginosa biofilms, it has good potential for use as an alternative antimicrobial in treating P. aeruginosa-associated biofilm infections.",

This was a cross-sectional observational study. A total of 60 participants were enrolled, including 20 normal controls, 20 patients with OLP alone (OLP group), and 20 patients with both OLP and T2DM (OLP_DM group). Salivary samples were subjected to 16S rRNA sequencing and untargeted metabolomics to assess microbiological and metabolic differences across the groups. Spearman's correlation analysis was used to evaluate associations between clinical characteristics and microbial or metabolic features. Alpha diversity (Chao1 index) was significantly reduced in both disease groups compared to the controls, while beta diversity analysis revealed no remarkable separation among groups. At the genus level, the abundance of Pseudomonas was elevated in the OLP_DM group relative to both the OLP and control groups, and positively correlated with lesion severity. Metabolomic analysis revealed significantly lower levels of limonin and higher levels of thymine and epinephrine in the OLP_DM group compared to the OLP. Limonin was negatively correlated with lesion severity, whereas thymine and epinephrine showed positive correlations with both lesion severity and pain scores. The study provides comprehensive evidence of oral microbial dysbiosis and metabolic disturbances in patients with OLP concomitant with T2DM. The findings suggest an interplay between specific bacterial populations and metabolic alterations in the progression and severity of OLP concomitant with diabetes.",

Despite advances in antifouling coatings and regeneration strategies, repeated restoration of surface-enhanced Raman spectroscopy (SERS) sensitivity in static, protein-rich media remains difficult without degrading nanogap integrity, limiting longitudinal sensing. This work introduces a regenerative molecular sensor based on multiresonant plasmonic nanoprotruding meshes (MPNMs) that co-localizes SERS sensing and nanocavitation-based actuation within nanogaps anchored on a biocompatible polymeric mesh. The nanogaps are engineered to support an electric-dipole resonance for SERS enhancement and a magnetic-dipole resonance for photothermal conversion, enabling femtosecond-laser-triggered nanocavitation within SERS-active nanogaps. Upon femtosecond-laser irradiation, collapse of vapor nanobubbles (\u2248200\u00a0ns lifetime) generates thermomechanical forces that detach and displace foulants with micron-scale precision to regenerate the nanogaps while preserving nanomorphology and optical performance. In undiluted human serum, regeneration restores detection limit for the\u00a0Pseudomonas aeruginosa\u00a0virulence factor pyocyanin from 2.0\u00a0\u00b5m to a clinically relevant 3.9\u00a0nm after 24\u00a0h of fouling. Repeated regeneration cycles enable spatiotemporal profiling of dynamic molecular signatures from\u00a0P. aeruginosa\u00a0biofilms in wound models over 24\u00a0h, establishing a self-regenerating platform for longitudinal molecular monitoring in protein-rich biosystems.",

(A Retrospective Cohort Study)].\nAbstract: Postoperative management of mastoid cavities after canal wall down (CWD) mastoidectomy remains challenging due to persistent otorrhea, infection, and delayed healing. Topical medications are widely used, but comparative data on their efficacy are limited. To evaluate the outcomes of different topical medications in patients with mastoid cavities following CWD mastoidectomy. A retrospective cohort study of 128 patients treated between 2015-2022. Groups included quinolone antibiotic drops (n=45), antiseptic agents (n=38), antifungal solutions (n=25), and combination therapy (n=20). Primary outcomes were resolution of otorrhea and epithelialization time. Secondary outcomes included complications and microbial resistance. Combination therapy (quinolone antibiotic + antiseptic) achieved the highest otorrhea resolution rate (95%) and shortest epithelialization time (6.2\u00b11.8 weeks). Antifungal agents had the lowest efficacy (68% resolution). Pseudomonas aeruginosa (32%) and Staphylococcus aureus (24%) were predominant pathogens, with quinolone antibiotic resistance observed in 18%. Combination topical therapy optimizes mastoid cavity healing, while antifungal agents should be reserved for confirmed fungal infections.

This study characterized the bacterial profile of endotracheal aspirate samples from a PICU in Sulaimani, confirmed A. baumannii identification using blaOXA-51 PCR, assessed antimicrobial resistance patterns, and determined genotypic diversity using ERIC-PCR. From August 2023 to March 2025, 100 consecutive Gram-negative isolates were recovered from mechanically ventilated pediatric patients. VITEK2 was used for identification and susceptibility testing. XDR Acinetobacter isolates underwent molecular confirmation via blaOXA-51 PCR, and confirmed isolates were genotyped using ERIC-PCR with UPGMA analysis. Among the 100 total isolates, A. baumannii accounted for 21 isolates alongside Pseudomonas aeruginosa (n\u2009=\u200933) and Klebsiella pneumoniae (n\u2009=\u200920). Given its clinical significance, A. baumannii was selected for further molecular characterization. Overall, 26 isolates exhibited XDR phenotypes, 12 of which were A. baumannii by VITEK2; 10 were confirmed by blaOXA-51 PCR (83.3%). All confirmed isolates were resistant to \u03b2-lactams, carbapenems, aminoglycosides, and fluoroquinolones, while remaining susceptible to colistin. ERIC-PCR revealed one dominant clone (Cluster A, 50%), two minor clusters (20% each), and one singleton (10%), indicating moderate genetic diversity with evidence of sustained clonal circulation. This study provides the first molecular epidemiological characterization of XDR A. baumannii in an Iraqi PICU, revealing clonal persistence of a successful epidemic strain and critical gaps in phenotypic identification. These findings emphasize the need for routine molecular surveillance, targeted infection control, and antimicrobial stewardship in resource-limited settings.",

This study compared the bactericidal efficacy of eight commercially available disinfectants - alcohols, hydrogen peroxide, quaternary ammonium compounds (QACs), and chlorhexidine (CHX) - against multidrug-resistant clinical isolates of Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, Enterococcus faecium, carbapenem-resistant Pseudomonas aeruginosa, and model organism Candida albicans as the most frequent causes of hospital-acquired infections in Croatia. Several formulations, particularly those based on QACs and CHX, retained full bactericidal activity even when diluted 10-32 times after only 1 min of contact, while alcohols were ineffective when diluted more than twice. However, all the formulations were effective when applied at full concentration. These findings highlight marked differences in the intrinsic bactericidal strength of commercial products, especially if not applied properly, which may explain variable outcomes observed in routine hospital disinfection practices. These issues may be overcome by rotating different disinfectant classes during routine surface decontamination and by optimising disinfectant strength to improve ARB and fungal control in clinical settings.

        "42398603": "ID: 42398603\nTitle: Targeting the FtsH protease unmasks a universal vulnerability to antimicrobial peptoids.\nAbstract: The rapid rise of multidrug-resistant (MDR) bacteria highlights the need for new antimicrobial agents beyond traditional mechanisms. Synthetic peptoids are promising therapeutics. Mechanistic studies reveal peptoids kill bacteria not by damaging membranes but by causing widespread macromolecular aggregation of intracellular proteins and nucleic acids. This proteotoxic stress challenges the bacterial ATP-dependent protease system, though precise defense pathways remain elusive. Understanding how bacteria counter this stress is essential for developing effective combination treatments. We showed that FtsH is the key protective mechanism, as only \u0394ftsH drives a 16-fold sensitization, identifying it as the bottleneck for survival under peptoid stress. Its protective role fundamentally depends on bacterial energy metabolism. Disabling FtsH increases susceptibility in Pseudomonas aeruginosa (P. aeruginosa), suggesting that FtsH represents a shared vulnerability across tested peptoid scaffolds. This uncovers a common vulnerability within the proteostasis network of MDR pathogens. FtsH is intrinsically less active under low-energy conditions typical of antibiotic-tolerant persister cells. This metabolic repression renders persisters uniquely susceptible to peptoid-induced proteotoxic stress. Combining the peptoid (TM5) with an FtsH inhibitor (carbonyl cyanide m-chlorophenyl hydrazone) or an energy-depleting compound is highly effective, providing a mechanism-driven strategy to overcome persister cell's drug tolerance.",

Chorismate synthase (AroC), a key enzyme in the aromatic amino acid biosynthetic pathway, is essential for central metabolism and has been implicated in bacterial virulence. In this study, an aroC deletion mutant (\u0394aroC) and a complemented strain (C\u0394aroC) were constructed to investigate the role of AroC in virulence regulation and to evaluate its potential as a live-attenuated vaccine candidate. Compared with the wild-type (WT) strain, \u0394aroC exhibited significantly reduced growth, motility, hemolytic activity, and biofilm formation. In infection experiments, \u0394aroC showed markedly attenuated virulence, resulting in 90% host survival. In a goldfish vaccination-challenge model, immunization with \u0394aroC conferred moderate protective efficacy, with a relative percent survival (RPS) of 62%. Transcriptomic analysis revealed that aroC deletion led to the downregulation of genes involved in amino acid metabolism, ABC transporters, and quorum sensing pathways. These results suggest that AroC contributes to pathogenicity by coordinating metabolic processes and environmental adaptation. Together, our findings identify AroC as an important virulence determinant in P. plecoglossicida and suggest that \u0394aroC is a promising live-attenuated vaccine candidate that warrants further validation in the natural host.",

We aimed to describe clinical characteristics, survival, post-transplant morbidity, and exploratory factors associated with mortality in a single-center Saudi cohort. We retrospectively reviewed all pediatric patients who underwent lung transplantation between January 2010 and December 2023. Demographic, anthropometric, perioperative, and post-transplant data were extracted. Survival was assessed with Kaplan-Meier analysis, and Cox regression was used to explore associations with mortality. Twenty-eight recipients underwent transplantation, predominantly bilateral sequential procedures, at a median age of 16\u2009years. All recipients were adolescents, and cystic fibrosis (CF) was the most common indication. Severe undernutrition was common, with 64.3% meeting failure-to-thrive criteria (<\u20091st centile for weight) and 71.4% below the 3rd centile. Intraoperative extracorporeal membrane oxygenation replaced cardiopulmonary bypass after 2016. One-year survival was 96.4%, and median post-transplant survival was 6.8\u2009years. Survival did not differ significantly by intraoperative extracorporeal support, but median survival was shorter in CF than in non-CF recipients (2.9 vs. 8.9\u2009years). Hypertension developed in 53.5% of patients, diabetes in 28.5%, and acute kidney injury in 46.4%. In age- and sex-adjusted Cox models, CF, longer waiting time, Pseudomonas aeruginosa colonization, and diabetes at 1\u2009year were associated with mortality. Pediatric lung transplantation in this cohort achieved excellent short-term survival but substantial long-term morbidity. Mortality associations should be interpreted cautiously, given the small sample size and event count. The shorter survival observed in CF recipients warrants further study, particularly in the context of severe undernutrition and chronic airway colonization.",

Within a Pseudomonas aeruginosa (P. aeruginosa)-infected plant biotic stress model, the analyzer achieved: (1) spatiotemporal mapping of virulence kinetics through sensitive detection of P. aeruginosa-specific virulence factor pyocyanin, establishing infection progression timelines and tissue-specific dissemination gradients. (2) Quantification of stress-responsive signaling via dual-functionalized Au@AgNCs, revealing methyl salicylate (MeSA) release kinetics and establishing a direct correlation between pathogen invasion severity and airborne alarm signal-a calibrated defense response heretofore unquantified. (3) Real-time in situ monitoring of MeSA-mediated PPC revealed fundamental plant physiological breakthroughs: First, receiver-specific signaling reprogramming occurs where healthy plants exhibit delayed yet amplified defense hormone kinetics, contrasting sharply with the immediate response of infected emitters. Second, evolutionarily constrained coordination emerges through cross-species signaling divergence, where phylogenetic adaptations in phytohormone perception circuits drive distinct defense strategies-exemplified by Solanaceae amplification versus Poaceae suppression.

Here, we analyzed the prevalence and genotype distribution of VFGs in P. aeruginosa isolated from Nanyang Central Hospital (NYCH), China, along with their antibiotic susceptibility profiles. The study involved 79 multidrug-resistant (MDR) and 96 non-MDR (nMDR) strains and the following 11 key VFGs (nan1, pilA, aprA, phzS, plcH, toxA, lasB, exoS, exoU, exoT, exoY). Antibiogram profiling showed near-universal resistance to at least one antibiotic class. MDR strains exhibited 23 distinct antibiotic resistance patterns, compared with 13 patterns in nMDR strains. A moderate negative correlation was observed between \u03b2-lactams/\u03b2-lactamase inhibitors and fluoroquinolone resistance. Moreover, statistical analysis revealed that the phzS gene displayed the most significant prevalence difference between MDR and nMDR subgroups (P < 0.001). Finally, 28 distinct genotypes were identified in nMDR isolates, and 26 genotypes appeared in MDR strains. There was a statistically significant correlation found between the presence of genotype XX (r = 0.481, P < 0.001) and genotype XXVIII (r = -0.320, P < 0.001) in two subgroups. Collectively, our findings provide data support for understanding the pathogenic mechanism of local P. aeruginosa, and are of great significance for guiding clinical anti-infection treatment and infection control.IMPORTANCEPseudomonas aeruginosa is an opportunistic pathogen notorious for causing difficult-to-treat infections, particularly among hospitalized patients in resource-limited healthcare settings. This study analyzed clinical isolates from a major hospital in China to investigate the prevalence and genotypic distribution of virulence factor genes (VFGs) and antibiotic susceptibility profiles of P. aeruginosa. Our results showed that multidrug-resistant (MDR) strains displayed more complex and diverse resistance profiles than non-MDR (nMDR) strains. Both MDR and nMDR isolates exhibited high genotypic diversity. Notably, a statistically significant association was observed between genotype XX and genotype XXVIII across the two subgroups. These findings elucidate the molecular basis underlying the variable treatment difficulty of P. aeruginosa infections and offer valuable insights for guiding empirical antibiotic selection. Characterizing local bacterial features, including antibiotic susceptibility profiles and the distribution of clinically relevant virulence factors, may improve understanding of regional resistance trends and support antimicrobial stewardship and infection control efforts.",

Among their diverse metabolites, hydrogen cyanide (HCN) is traditionally considered a potent antimicrobial compound, yet its broader role in plant-microbe interactions remains underexplored. This study investigated Pseudomonas urmiensis A32, an endophytic bacterium previously shown to enhance drought tolerance and disease resistance in pepper (Capsicum annuum). Whole-genome analysis revealed genes involved in nutrient acquisition, stress protection, and competitive exclusion, including secondary metabolite clusters for carotenoid and HCN biosynthesis. Wild-type A32 showed increased tolerance to oxidative stress, highlighting a redox-active role for HCN. Seed inoculation with A32 reduced disease symptoms and pathogen load in pepper plants challenged with Xanthomonas euvesicatoria, indicating that HCN contributes not only to direct pathogen antagonism but also to modulation of host immune responses. Biochemical analyses showed decreased activity of antioxidant enzymes and increased phenylalanine ammonia-lyase activity. Gene expression analyses revealed upregulation of PR1 and the antimicrobial peptide gene DEF1, indicating enhanced activation of defence genes. These findings demonstrate that HCN acts as a multifunctional metabolite that fine-tunes the balance between reactive oxygen species detoxification and signalling, and integrates microbial biocontrol with host immune priming. In summary, this work highlights the ecological adaptability of P. urmiensis A32 and its potential as an effective bioinoculant for sustainable crop protection.",

The widespread application of organophosphate esters (OPEs) has led to their frequent detection in aquaculture water, posing potential risks to the aquatic ecosystems and human health. In this study, we revealed that exposure to five types of OPEs (0.1-1000\u202f\u00b5g/L) promoted the dissemination of RP4 plasmid from Escherichia coli to Pseudomonas alcaligenes, a multidrug-resistant bacterium isolated from actual aquaculture wastewater. Through the application of fluorescence detection, scanning electron microscopy, RT-qPCR, and RNA-seq techniques, we clarified at the cellular and molecular levels that OPEs promoted plasmid conjugation transfer by inducing reactive oxygen species (ROS) accumulation, activating the stress response (SOS), enhancing cell membrane permeability, improving intracellular energy supply, regulating the expression of conjugation-related genes, and activating the transfer apparatus encoded by RP4. Specifically, TBEP was selected as a representative OPE to systematically explore its impact on plasmid dissemination. Notably, a frequently overlooked aspect was that exposure to TBEP also enhanced the genetic stability and expression persistence of ARGs. Our findings emphasized that OPEs released from aquaculture facilities might act as driving factors to promote intergenus horizontal transfer of ARGs in actual aquaculture environments-a potential risk that has not yet been fully recognized.",

Understanding global patterns is essential for guiding therapy and stewardship. We conducted a systematic review and meta-analysis of studies reporting C/T resistance in Pseudomonas aeruginosa and Acinetobacter baumannii. Pooled resistance proportions were estimated using random-effects models, with subgroup analyses by species, resistance phenotype, infection source, geography, and study period. Heterogeneity, temporal trends, and potential biases were assessed. Among 75,403 tested isolates, 14,379 were resistant, yielding an overall pooled C/T resistance estimate of 26.2%. P. aeruginosa showed moderate resistance (12.6%), rising sharply in MDR (21.8%) and XDR (44.4%) subsets. A. baumannii demonstrated near-universal resistance (88.2%), particularly among carbapenem-resistant strains (\u224899%). Resistance increased over time, from 19.9% in 2013-2021 to 38.7% in 2022-2024. Geographic differences were notable: high prevalence in Germany (46.6%), Mexico (42.6%), and Egypt (41.3%), and lower rates in Taiwan (15.1%) and Canada (1.7%). Respiratory isolates exhibited the highest resistance (49.4%), whereas bloodstream and pediatric infections were lower, though data were limited. Subgroup analyses for XDR, PDR, and carbapenemase producers were constrained by small study numbers. C/T retains activity against many P. aeruginosa isolates but is increasingly compromised in MDR/XDR and carbapenemase-producing strains. A. baumannii shows consistently high resistance, limiting C/T utility. Rapidly rising resistance, infection-site variability, and geographic heterogeneity highlight the urgent need for targeted stewardship, local susceptibility-guided empiric therapy, and ongoing research into alternative or combination therapies.",

Reliable tools to evaluate intervention effectiveness are needed. This study applied a parametric survival analysis using the two-parameter Weibull model to assess outcomes among patients with carbapenem-sensitive A. baumannii (CSAB) infections. Data were drawn from a retrospective case-series in a regional hospital in southern Taiwan, including both community and healthcare-associated cases. The intervention combined targeted antimicrobial therapy, intensified environmental disinfection with 0.5% sodium hypochlorite in four ICUs for one month, and an educational campaign. Weibull parameters were estimated via least squares regression to compare survival functions before and after intervention. Results showed improved survival, with scale (\u03b1) increasing from 33.88 to 56.05 days and shape (\u03b2) from 0.894 to 0.948, indicating a more favorable profile. The monthly incidence of healthcare-associated infections decreased from 3.18\u2030 to 2.87\u2030 in the subsequent year, with the most pronounced reduction occurring between months 2 and 4. These findings demonstrate the utility of Weibull modeling in monitoring intervention reliability and suggest that parameter trajectories may serve as early indicators for adjusting strategies.

This study applied a bacterial genome-wide association study (bGWAS) framework to identify genetic factors beyond the canonical carbapenemase OXA-23, that may contribute to carbapenem resistance. A. baumannii isolates with publicly available whole-genome sequencing (WGS) data and carbapenem-specific antimicrobial susceptibility testing (AST) results were compiled (n\u2009=\u20091,601). Unitigs were extracted from de novo assemblies, and single-nucleotide polymorphisms (SNPs) were called from raw sequence reads mapped to seven selected reference genomes. The unitig- and SNP-based genome-wide association analyses were carried out, including conditional analyses based on the known resistance determinants. Structural analysis was performed for the select candidate mutations. The population was highly clonal and comprised ten lineages, including three predominantly resistant lineages (ST1, ST2, and ST32). Known CRAB-associated loci, including OXA-23, the RND efflux pump regulator AdeL, and OXA-66 variants (Ile129Leu and Leu167Val), were readily identified. Structural analysis of mutations identified outer-membrane proteins as potential candidate loci, however these loci were not supported in the conditional analyses across all reference genomes. The candidate loci supported in the conditional analysis across reference genomes included an amino acid substitution in a LysR-type regulator adjacent to the biofilm-associated operon pgaABCD, and an intergenic substitution located between enzymes involved in LPS remodeling. OXA-23 is the major determinant of carbapenem resistance in A. baumannii. Additional resistance mechanisms may become significant in the absence of OXA-23, including efflux pump regulation (AdeL), membrane permeability (OprD, DcaP), lipopolysaccharide (LPS) transport (PqiB), LPS remodeling (acyltransferase, glycosyltransferase), and biofilm formation (LysR). Integration of the conditional analysis based on known resistance determinants and a multi-reference mapping framework may improve the detection and prioritization of candidate associations.",

Here, we show that the cyanobacterium Microcystis aeruginosa enhances extracellular superoxide production by Pseudomonas sp. QJX-1 under illumination. Cocultivation increased extracellular superoxide production approximately threefold over bacterial monoculture, with maximum enhancement during carbon starvation. Membrane separation localized detectable superoxide production to the bacterial chamber, indicating that diffusible algal products stimulated bacterial superoxide production. Mechanistically, illuminated cocultures showed 20.4% higher photocurrent than algal monocultures and accumulated the highest extracellular NADP(H) levels, indicating intensified photosynthesis-associated extracellular redox activity. Reduced nicotinamide cofactors stimulated diphenyleneiodonium-sensitive QJX-1-associated superoxide production, consistent with an oxidoreductase-associated route for one-electron reduction of molecular oxygen. In parallel, coculture accumulated catecholate siderophores, consistent with intensified microscale Fe competition; this siderophore-enhanced response required metabolically active bacterial cells and was attenuated by respiratory-chain inhibition. Representative extracellular redox-active and algal photoactive components further enhanced the bacterial response, with cytochrome c and chlorophyll a stimulating QJX-1-associated superoxide production under defined conditions. Functionally, during the carbon-starvation interval coinciding with peak superoxide production, the apparent sulfamethoxazole removal rate constant in coculture was 2.6 times that observed for QJX-1 alone. Moreover, quenching extracellular reactive oxygen species impaired metabolic activity under diverse chemical stressors and reduced carbon, nitrogen, and phosphorus substrate utilization. Collectively, these findings identify photosynthesis-dependent phycosphere interactions as regulators of bacterial superoxide production, linking biogenic reactive oxygen species to contaminant transformation, chemical-stress resilience, and elemental nutrient turnover.",

The escalating misuse of antibiotics has led to the emergence of multidrug-resistant strains, necessitating novel therapeutic approaches. Bacteriophages and their encoded lytic enzymes offer unique advantages for antimicrobial therapy and show promising potential for future applications. This study focuses on the characterization of uropathogenic P. aeruginosa phages and their lytic enzymes, investigating their biological properties and potential therapeutic applications. We isolated a novel lytic bacteriophage, vB_PaeS_PA16c (PPA16c), which demonstrated favorable biological characteristics, including a 34% biofilm eradication capacity within 6\u2009h. The phage-encoded endolysin PA16cLys exhibited superior antibacterial efficacy compared to the phage itself. Notably, it achieved significant biofilm reduction (~63%) after 1\u2009h treatment without requiring outer membrane permeabilizers. This endolysin exhibited enhanced antibacterial efficacy in eradicating mature P. aeruginosa biofilms. Regarding host range, PA16cLys displayed broader lytic activity.

However, the high ammonia (NH3) concentration and low biodegradability of CM limit hydrolysis and methane production. This study investigated the application of a current-carrying-coil-based magnetic field (CCC-MF) to AD of CM. The CCC-MF digesters showed higher soluble chemical oxygen demand and attained 16.59\u00a0% higher ammonium nitrogen reduction, contributing to a 37.50\u00a0% higher average methane yield than the control. Further, CCC-MF digesters showed higher enzyme activities (alkaline protease\u00a0+\u00a030\u00a0%, acetate kinase\u00a0+\u00a022\u00a0% and hydrazine dehydrogenase\u00a0+\u00a026\u00a0%) and increased microbial metabolic indices (dehydrogenase activity\u00a0+\u00a017\u00a0% and electron transport system activity\u00a0+\u00a010\u00a0%) than the control. Metagenomics analysis revealed that abundances of the bacterial genera Mesotoga, Aminobacterium, Xiashengella, unclassified Candidatus Cloacimonadota, Advenella, Pseudomonas, and Comamonas increased, whereas the acetoclastic methanogen Methanothrix decreased by 2.58\u00a0%, accompanied by 2.07- and 1.64-fold increases in hydrogenotrophic methanogens Methanospirillum and Methanobacterium, respectively, in CCC-MF digesters. The abundance of nitrogen dissimilation and assimilation genes NirK, NorB, NarB, NapA, nmo, and GLT1 were enhanced by 1.14, 1.04, 2.30, 1.32, 1.17, and 1.29-fold in CCC-MF digesters compared to the control. Moreover, metaproteomics revealed higher up-regulated differentially expressed proteins in NH3 reduction-related amino acid metabolism pathways in CCC-MF digester compared to control. Additionally, reduced abundances of bacitracin, polymyxin, sulfonamide, and multidrug antibiotic resistance (MAR) gene types were observed in the CCC-MF digesters. The findings suggest that applying CCC-MF may be associated with higher methane production and ammonium reduction, potentially linked to a more favorable synergistic methanogenic system and nitrogen transformation pathways.",

Surface morphology and elemental composition were analyzed by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), and antimicrobial and antibiofilm activity was quantified by determining the number of colony-forming units (CFU\u2215mL) for Gram-positive bacteria (Staphylococcus aureus, Enterococcus faecalis), Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), and fungi (Candida albicans, C. parapsilosis). FOZ exhibited a very rough surface rich in zinc, associated with the most pronounced reduction in microbial adhesion; CIS showed a relatively compact ionomer matrix with barium-rich domains and good antibiofilm activity, particularly against P. aeruginosa, while DT exhibited a predominantly organic, smooth surface with isolated inorganic aggregates and a more pronounced inhibition profile against E. coli. The results indicate that the microstructure and surface chemical composition of the cements directly influence the pattern of microbial colonization and antibiofilm efficacy, providing a rationale for selecting the cementing material based on microbiological risk and specific clinical conditions.",

In this study, Streptomyces sp. KJ7TB2 was isolated from the Indian Sundarbans. An ethyl acetate extract was subjected for GC-MS profiling. The mechanisms of antibacterial and antibiofilm action were also explored. In-silico molecular docking and dynamics simulation analyses were performed. The GC-MS analysis of the extract revealed 14 distinct bioactive secondary metabolites. The extract exhibited potent MIC values of 250\u2009\u03bcg/mL and 125\u2009\u03bcg/mL against Escherichia coli MTCC 1195 and Pseudomonas aeruginosa ATCC 27853. Antibiofilm investigation further revealed inhibition of biofilm formation in both pathogens especially in E. coli MTCC 1195, likely by disrupting initial surface adhesion and exopolysaccharide synthesis. Also, the extract inhibited swarming motility, suggesting interference with flagella-driven motility and quorum sensing. The brine shrimp lethality assay confirmed a favorable safety profile, recording limited mortality (36.84% at 2\u00d7MIC over 24\u2009h). In-silico molecular docking and dynamics simulation analyses exhibited robust affinity for two key biofilm-associated proteins, exhibiting significant binding energy (\u0394G). The study highlights Streptomyces sp. KJ7TB2 as a potential source for the discovery of safe, potent therapeutics. Exploring a Mangrove-derived microbe to fight against drug-resistant germs. Antibiotic resistance is a serious global health risk. Many antibiotics do not work as well as before. Because of this, bacterial infections are becoming harder to treat. Scientists are looking for new medicines from natural sources. In this study, we found a rare, helpful microbe from the mangrove forests of the Indian Sundarbans. These forests contain many useful microorganisms. A rare bacteria called Streptomyces sp. KJ7TB2 was collected and grown in the laboratory. After cultivation of the bacteria and collecting its extract, chemical studies found 14 useful compounds. The extract showed strong activity against harmful bacteria. It also stopped the bacteria from building protective walls around themselves. It blocks the signals of the bacteria use to talk with each other. Computational studies also supported these results. Safety tests showed very low toxicity of the extract. This means it may be safe for future studies. Overall, this study suggests that Streptomyces sp.

The in vitro antimicrobial properties of STF were analyzed using checkerboard assays to determine the fractional inhibitory concentration (FIC) index. The cytotoxicity of STF was determined using the MTT viability assay using L929 fibroblasts. The in vivo efficacy of STF was assessed using a rat excisional wound model, and wound closure rates were measured at 14\u2009days post-infection. STF showed an additive interaction in the in vitro model (FIC index: 0.717-0.936) and possessed low cytotoxicity (IC50: 705.4\u2009\u00b5g/mL) compared to the individual compounds. In the in vivo model, the group treated with STF showed significantly faster wound healing and decreased inflammation compared to all other groups, including the silver sulfadiazine group.

This case report aimed to investigate changes in the skin microbiome of a patient with Netherton syndrome before and during dupilumab therapy, with the goal of expanding the limited evidence currently available on this topic. We report the case of a 35-year-old woman diagnosed with NS at birth, who, prior to dupilumab therapy, presented with atopic dermatitis (AD), ichthyosis linearis circumflexa, and severe pruritus. Dupilumab therapy was initiated, and skin swabs were collected from lesional sites at three different time points: at baseline, after 1\u202fmonth, and after 1\u202fyear of continuous dupilumab therapy. At baseline, a microbiome analysis revealed low microbial diversity with a predominance of Pantoea and Pseudomonas species. After 1\u202fyear, a significant increase in microbial diversity, with a predominance of Staphylococcus species and an increase in Malassezia species, was observed. Clinically, the patient experienced remission in parallel with these microbiome shifts. Post-treatment, the skin microbiome showed increased microbial diversity and re-establishment of beneficial commensals, more closely resembling healthy skin.

The mammal gut demonstrates an interesting source of virulence bacteriophages. The gut with inflammation is phage-rich; therefore, we primarily aimed to prove the concept that an inflammatory gut is a possible source of effective phages and to evaluate the efficacy of the candidate phage against Pseudomonas aeruginosa in vitro and in a mouse model of infected wounds. The gut microbiome of cecal ligation and puncture (CLP) sepsis mice, an animal model of inflammation, showed a dominant presence of Podoviruses. CLP bacteriophages (CLP \u03a61-\u03a64), of which the CLP \u03a64 possessed the broadest bactericidal activity (viable bacterial cell reduction in time-kill study) against P. aeruginosa isolates. The CLP \u03a64 specifically killed the Pseudomonas aeruginosa clinical (PACL) strain with two huge burst events. Although the CLP \u03a64 had no effect on ex vivo mouse bone marrow-derived macrophage (BMDM) cytokine gene expression and cytokine production, the CLP \u03a64 attenuated the severity of the P. aeruginosa-infected wound mouse model after treatment. P. aeruginosa PACL exhibited significantly pathogenic characteristics in a mouse model, including excessive bacterial loads (in wounds and internal organs, indicating the systemic infection due to localized infected wound with P. aeruginosa), increased IL-6 cytokine (in serum), upregulated IL-6 expression (in wounds), and immune cell infiltration (in wounds), indicating severe inflammation. In the CLP \u03a64 treatment alone, the wound tissues upregulated IL-10 expression and recruited inflammatory cells. Interestingly, the three-day CLP \u03a64 treatment was adequate to eradicate P. aeruginosa PACL in the wounds and other internal organs. After treatment, the mouse serum cytokine showed a remarkably decreased IL-6. Likewise, IL-6 downregulation and IL-10 upregulation were demonstrated in the treated wounds, suggesting an anti-inflammatory shift. These results demonstrated the effectiveness (bacterial wound and internal organ clearance and cytokine modulation) of the CLP \u03a64 in the P. aeruginosa-infected wound and systemic infection. Finally, the CLP \u03a64 isolation verified a proof of concept that the irritated gut acts as a source of bacteriophages. The gut virome was a promising and interesting source of antimicrobial and immunomodulating bacteriophage.",

Optimizing treatment and identifying mortality-related factors are urgently needed. To compare the efficacy of different antibacterial regimens in MDRAB pneumonia and determine independent risk factors for 28-day all-cause mortality. This single-center retrospective cohort study included 142 MDRAB pneumonia patients from February 2022 to February 2025. Patients were divided into three groups: Group A, sulbactam-containing combinations (n = 63); Group B, polymyxins + tigecycline (n = 45); Group C, other regimens (n = 34). Outcomes included bacterial resistance patterns, 28-day mortality, dynamic PCT and CRP levels, APACHE II and SOFA scores, and lymphocyte subsets. Multivariate logistic regression identified mortality predictors. Group A showed the lowest resistance to cefoperazone/sulbactam (30.16%) and the highest sensitivity (71.43%, both P< 0.05). Group B had the highest tigecycline resistance (31.11%). The 28-day mortality rates were 39.68% (A), 60.00% (B), and 64.71% (C) (P\u00a0=\u00a00.028).

Using the Global Burden of Disease (GBD) 2021 database, we analyzed sepsis in 0-14-year-olds, covering 62 pathogens (21 drug-resistant), 84 \"pathogen-drug\" combinations, 12 infection syndromes, and indicators (deaths, disability-adjusted life years [DALYs], age-standardized rates). Antimicrobial resistance (AMR) was defined by two counterfactual scenarios; an autoregressive integrated moving average (ARIMA) model forecast AMR-related sepsis to 2050. From 1990 to 2021, global sepsis-related deaths among children declined from 6.43 million to 2.24 million, and DALYs dropped from 578 million to 203 million. The estimated annual percentage change (EAPC) in age-standardized mortality rate (ASMR) and DALY rate (ASDR) was -3.35 and -3.33, respectively. AMR-related sepsis burden also decreased, with notable declines in both AMR-associated and AMR-attributable deaths and DALYs. In 2021, the highest burden remained in Sub-Saharan Africa, while the lowest was in High-income regions. Leading pathogens causing child sepsis deaths included Streptococcus pneumoniae, Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa. Bloodstream infections, lower respiratory infections, and diarrhea were the most common infection syndromes leading to sepsis-related deaths. Global childhood sepsis burden dropped, but high-burden regions (e.g., Sub-Saharan Africa, South Asia) need focus.

In this study, we report a simple, low-cost, and eco-conscious approach for synthesizing silver nanoparticles (AgNPs) using an aqueous zest extract of Citrus sinensis (Cs), which naturally serves as both the reducing and stabilizing agent. The phytochemicals present in the extract-including ascorbic acid, phenolic acids, flavonoids, terpenoids, and polysaccharides-effectively reduce Ag+ ions to stable AgNPs. The formation of AgNPs was confirmed through UV-Vis spectroscopy, revealing a characteristic surface plasmon resonance peak at 420 nm. FESEM imaging demonstrated predominantly spherical nanoparticles with uniform crystallite morphology and rough surface features, while TEM analysis showed an average particle size of approximately 15 \u00b1 5.3 nm. XRD patterns confirmed the polycrystalline nature of the particles with diverse d-spacings, and EDX analysis indicated high purity (93.91% Ag) of the synthesized material. Compared to previously reported green synthesized nanoparticle systems, the biosynthesized AgNPs displayed excellent catalytic activity, achieving dye removal efficiencies of 98.93% (within 18 min) for methyl orange (MO) and 92.15% (within 30 min) for methylene blue (MB) under mild conditions, highlighting the advantage of waste-derived plant extract-mediated synthesis.

However, like other oxidized terpenes, its limited biosynthetic availability hinders its development as a therapeutic lead. Cytochrome P450 monooxygenase CYP153A6 catalyzes the key hydroxylation of limonene to yield perillyl alcohol in Escherichia coli, yet the enzyme is the rate-limiting step in this pathway and has not previously been improved by directed evolution. Here, we report the development of a genetically encoded biosensor based on the cymene repressor CymR from Pseudomonas putida F1, engineered to selectively detect perillyl alcohol over its non-hydroxylated precursor limonene, and its application to the directed evolution of CYP153A6. A single substitution (S77L) in the CymR effector-binding pocket dramatically increased biosensor sensitivity and dynamic range toward perillyl alcohol while maintaining discrimination against limonene. The tailored CymR-S77L biosensor was coupled to a CYP153A6 random mutant library to enable high-throughput fluorescence-based screening of variants. Ultimately, seven CYP153A6 variants, some with multiple mutations, were identified to have improved perillyl alcohol titers. Deconvolution of beneficial mutations revealed that a single substitution, A287T, located near the predicted CYP153A6:ferredoxin reductase interface, was sufficient to increase perillyl alcohol productivity 4.2-fold relative to wild-type without compromising regio- or chemoselectivity. These results demonstrate that biosensor-guided directed evolution is an effective and selective strategy for engineering P450-dependent terpene hydroxylation pathways and establish a generalizable platform for developing monoterpene-responsive biosensors and applying them to the directed evolution of terpene-modifying enzymes.",

This study evaluated the effects of balanced experimental diets supplemented with inulin or yeast cell wall (prebiotics), Lactobacillus acidophilus (probiotic), or their combination (synbiotics) on juvenile pike silverside (Chirostoma estor). Growth performance was monitored, and gut microbiota composition was characterized by 16S rRNA gene metabarcoding. Synbiotic and yeast cell wall supplementation significantly improved growth parameters, including weight gain, final body weight, and specific growth rate, compared to the control. Microbiota profiling revealed a core community of nine genera (Bacillus, Citrobacter, Cutibacterium, Lactobacillus, Pseudomonas, Spiroplasma, Stenotrophomonas, Streptococcus, and Thermogemmatispora), with each treatment inducing distinct shifts in bacterial composition. Candidate probiotic taxa, including Lactobacillus spp., were also identified as part of the gut microbial response to dietary treatments. Functional predictions further indicated an enrichment of bacterial biosynthetic pathways in synbiotic and yeast cell wall treatments, aligning with the observed improvements in growth and feed efficiency. These findings indicated that yeast cell wall and synbiotic supplementation modulated gut microbial composition and were associated with improved growth performance in C.\u00a0 estor, underscoring the role of microbiome-targeted nutrition in this species.",

However, the microorganisms involved and their resistance patterns in DUWLs remains unclear. This scoping review aimed to map the available evidence on antimicrobial-resistant microorganisms in DUWLs and characterize resistance patterns. We conducted a systematic literature search across the PubMed, Scopus, and Web of Science databases up to March 2026. Studies that reported the isolation of microorganisms from DUWLs and AMR using phenotypic methods and/or genotypic detection of antimicrobial resistance genes (ARGs) were included. Data were extracted and summarized descriptively. A total of 18 studies were included. Most studies analyzed DUWL water samples and reported bacterial isolates, particularly Gram-negative organisms such as Pseudomonas spp. Phenotypic antimicrobial susceptibility testing was performed in 16 studies, with \u03b2-lactams, aminoglycosides, and fluoroquinolones being the most frequently evaluated classes. Ciprofloxacin and gentamicin were the most commonly tested antibiotics. AMR was reported in 15 studies, with frequent resistance to \u03b2-lactams and multidrug resistance. Fungal microorganisms showed reduced susceptibility in biofilms compared to planktonic forms. Genotypic data were limited, and no ARGs were detected in the two studies that assessed them. DUWLs can become sources of antimicrobial-resistant microorganisms. However, the current evidence remains limited due to methodological variability and insufficient genotypic data.

In this study, we present a highly effective bienzymatic cascade coupling the (S)-selective \u03c9-transaminase from Pseudomonas psychrotolerans (PpS-TA) with pyruvate decarboxylase from Zymomonas mobilis (ZmPDC). This integrated system uses ZmPDC to irreversibly remove the pyruvate coproduct, thereby shifting the equilibrium toward the desired amine. Optimization of the purified enzyme system resulted in a twofold increase in conversion compared to the transaminase alone. The cascade exhibited broad substrate scope across various substituted benzaldehydes and simultaneously enabled the formation of valuable (R)-acyloin byproducts through the carboligation activity of ZmPDC. To enhance industrial applicability, the cascade was transferred to a whole-cell system using an engineered Escherichia coli strain (RARE), which minimizes undesired endogenous aldehyde reduction. The coexpressed whole-cell biocatalyst exhibited superior productivities at substrate loadings up to 50\u2009mM without the need for organic cosolvents. Finally, the utility of this approach was demonstrated through the chemo-enzymatic synthesis of the bio-based platform molecule 2,5-bis(aminomethyl)furan from d-fructose, achieving an exceptional 90% conversion on a 500-mL preparative scale.

To guide empiric treatment strategies and to build real evidence, we conducted a retrospective analysis of antimicrobial susceptibility patterns from urine cultures obtained at a university hospital. Antimicrobial susceptibility test (AST) results from initial positive urine cultures (n=11,358, both inpatients and outpatients) collected between 2016 and 2024 were reviewed. The analysis focused on predominant gram-negative isolates-Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Pseudomonas aeruginosa. Resistance rates were determined for twelve commonly used antimicrobials, including third- and fourth-generation cephalosporins, \u03b2-lactam/\u03b2-lactamase inhibitor combinations, carbapenems, aminoglycosides, fluoroquinolones, trimethoprim/sulfamethoxazole, nitrofurantoin, and fosfomycin. Between 2016 and 2024, AST identified E. coli (n=6,533), K. pneumoniae (n=1,348), P. mirabilis (n=677), and P. aeruginosa (n=663). While fluoroquinolone resistance remained persistently high (31.5%-44.5% in E. coli, 6.9%-37.0% in K. pneumoniae), its annual trend showed to be stable. Cefepime resistance increased steadily in most gram-negative isolates (annual percentage change [APC]=16.1%-25.0%). Although Carbapenem resistance remained low but it increased steadily in E. coli and K. pneumoniae (APC=22.2%). Nitrofurantoin and fosfomycin retained strong activity against E. coli, though their efficacy varied among other pathogens.

Furthermore, it reduced biofilm-associated carbohydrates by 66.9%, proteins by 66.22%, and extracellular DNA by 69.57%. In silico analysis revealed that Aloin interacts with key P. aeruginosa proteins, such as RhlI (Glide Score: -6.035\u00a0kcal/mol; Glide e-model score: -60.414\u00a0kcal/mol), LasI (Glide Score: -4.407\u00a0kcal/mol; Glide e-model score: -35.286\u00a0kcal/mol), LasR (chain A) (Glide Score: -3.764\u00a0kcal/mol; Glide e-model score: -36.012\u00a0kcal/mol), LasR (chain B) (Glide Score: -5.015\u00a0kcal/mol; Glide e-model score: -46.672\u00a0kcal/mol), PqsR (Glide Score: -4.701\u00a0kcal/mol; Glide e-model score: -25.491\u00a0kcal/mol), PelA (Glide Score: -6.097\u00a0kcal/mol; Glide e-model score: -53.723\u00a0kcal/mol), and PelB (Glide Score: -5.043\u00a0kcal/mol; Glide e-model score: -53.128\u00a0kcal/mol) by forming strong hydrogen bonds. In silico simulation studies also substantiated the Aloin-protein binding results. The production of virulence factors, such as exoprotease and pyocyanin, was reduced by 71% and 74%, respectively.

These results suggest that Aloin from Aloe vera has the potential to be an effective biofilm inhibitor without toxicity, with broad applicability.",

It is extensively applied in agricultural and household settings due to its broad-spectrum insecticidal properties. However, its persistence, bioaccumulative behavior, and toxicological effects on non-target organisms, including humans, pose significant environmental and public health concerns. CP and its metabolites, particularly two including 3,5,6-trichloropyridinol (TCP) and chlorpyrifos-oxon (CPO), have been recently reported to be widely found various samples such as in soils, sediments, water bodies, crops, and even human biological fluids. These compounds disrupt biogeochemical cycles, alter soil microbial communities, inhibit enzyme activities, and are linked to neurotoxicity, endocrine disruption, and genotoxic effects. Conventional remediation strategies such as photodegradation, ultrasonication, and filtration remain ineffective due to incomplete degradation and secondary pollution risks. Recent studies highlight the efficiency of microbial degradation, especially by bacteria such as Bacillus, Klebsiella, Pseudomonas and Enterobacter as a promising, eco-friendly alternative. These microorganisms utilize CP as a only carbon source, and degradation calibre is greatly governed by various abiotic factors like pH, temperature, and moisture. The genetic as well as enzymatic analyses reveal key roles of organophosphorus hydrolases encoded by genes such as opd and mpd. The integration of plant growth-promoting traits and laccase activity further enhances their bioremediation capability. Additionally, recent advancements in biosensing techniques for CP detection offer improved sensitivity and real-time monitoring. This review provides a comprehensive analysis of CP's environmental fate, toxicological impact, degradation pathways, and the emerging role of bacterial bioremediation, highlighting its potential for sustainable environmental detoxification.",

This study aimed to establish a comprehensive genomic framework for the rational prioritization of virulent Acinetobacter bacteriophages as therapeutic candidates. We performed large-scale comparative genomic analysis of 340 virulent Acinetobacter bacteriophages, integrating phylogenetic reconstruction, pangenome analysis, CRISPR spacer-based host interaction mapping, Anti-CRISPR protein identification, and systematic antimicrobial resistance (AMR) gene screening. Genome sizes spanned a nearly 20-fold range, with a significant negative correlation between genome size and GC content (R\u00b2 = 0.139, \u03c1 = -0.630). Phylogenetic analysis revealed extensive divergence across multiple lineages with no dominant clade. Pangenome analysis identified 20,982 unique protein families, of which 76.2% were cloud genes, confirming a highly open genome architecture. CRISPR spacer matching yielded 1,480 high-confidence matches across 100 phage genomes, providing molecular evidence of broad historical infectivity. Anti-CRISPR profiling identified Acinetobacter phage XC1 as an exceptional therapeutic candidate harboring 55 predicted Anti-CRISPR proteins with canonical regulatory locus architecture. AMR screening identified 21 distinct AMR gene homologs (Loose RGI hits, 22.5 to 47.1% amino acid identity) distributed heterogeneously across the dataset, confirming abundant therapeutically clean candidates while flagging a subset warranting further scrutiny before therapeutic exclusion. These findings provide a multi-criteria genomic framework for rational phage candidate prioritization against multidrug-resistant Acinetobacter infections, with direct implications for evidence-based phage therapy development.",

However, standardized laboratory workflows for simultaneous evaluation of total antioxidant capacity (TAC), pH behavior, culture-based no-detectable-growth status under defined conditions, and preliminary antimicrobial screening remain limited. Fresh inner-gel Aloe vera extract was prepared aseptically and formulated at 5%, 10%, 15%, and 20% (w/v). pH was measured potentiometrically, and TAC was determined by an automated ABTS radical cation-based colorimetric assay. Culture-based no-detectable-growth assessment was performed by inoculating the extract onto blood agar, eosin methylene blue agar, and Sabouraud dextrose agar, followed by aerobic incubation and visual inspection at 24 h, 48 h, and 72 h. Antimicrobial screening of a 70:30 (v/v) Aloe vera/N-acetyl-L-cysteine test mixture was performed against standard reference strains by disk diffusion and qualitative two-fold tube dilution assays. TAC differed significantly among groups (Kruskal-Wallis, p = 0.014), with the highest values observed in the 20% formulation. No visible bacterial or fungal growth was observed under the tested culture conditions during the 72 h observation period. The Aloe vera/N-acetyl-L-cysteine test mixture produced inhibition zones ranging from 11 mm to 17 mm, with the largest zone observed against Pseudomonas aeruginosa. This workflow provides a practical laboratory approach for preparing and preliminarily characterizing fresh Aloe vera.-based formulations for early-stage complementary medicine research.",

These pathogens are progressively acquiring pan-resistance and spreading beyond traditional healthcare settings, yet conventional diagnostic methods remain ill-equipped for point-of-care (POC) deployment due to slow processing times and limited adaptability. CRISPR/Cas systems feature programmable target specificity and intrinsic signal amplification, enabling rapid and accurate nucleic acid detection. Despite these advantages, the translation of CRISPR-based assays for ESKAPE pathogens from proof-of-concept to practical POC tools faces major challenges. Current research is fragmented, and key trade-offs between sensitivity, multiplexing performance and operational simplicity have not been fully addressed. This review offers a critical assessment of the field, moving beyond a simple summary of existing studies to analyze how various CRISPR systems (Cas9, Cas12, Cas13, and Cas14) and amplification strategies address the demands of POC testing. We identify key barriers to clinical application, particularly sample preparation, multiplex detection, reagent stability, and discuss emerging solutions such as microfluidic integration, lyophilized reagents development, and artificial intelligence-driven data interpretation. By focusing on the central question of how to transition from benchtop research to bedside application, this review provides a strategic framework for advancing next-generation CRISPR diagnostics capable of rapid, precise, and real-time detection of drug-resistant ESKAPE pathogens in the fight against AMR.",
        "42409126": "ID: 42409126\nTitle: Arginine metabolism and compensatory adaptations expand the impaired phage resistance repertoire in colistin-resistant Acinetobacter baumannii.\nAbstract: Limiting the emergence of phage resistance is a key priority in optimizing phage therapy. However, it remains poorly understood whether the development of antibiotic resistance influences the evolution of phage resistance. To investigate phage-host interactions, we used both colistin resistant strains derived from the wild-type and genetically engineered knockout mutants. Transcriptomic analysis was employed to examine the adaptive responses of these colistin-resistant mutants under phage pressure. Finally, we characterized the phage-resistant variants that evolved in the colistin-resistant backgrounds. Our results demonstrate that the emergence of phage-resistant variants was significantly reduced in colistin resistant mutants. These phenotypic changes were primarily mediated by disruption of lpxC and lpxD, with additional effects from compensatory mutations and amino acid metabolism. The \u0394lpxC and \u0394lpxD mutants exhibited distinct transcriptional profiles and metabolic features under phage pressure. The astA-mediated arginine metabolism pathway was a key modulator of phage-colistin-resistant mutant interactions. In the \u0394lpxD background, Mla system inactivation and arginine supplementation accelerated the phage resistance evolution (including via the mucoid phenotype). Capsule defects arising during phage resistance development in both \u0394lpxC and \u0394lpxD mutants simultaneously increased colistin susceptibility. Overall, lpxC/lpxD disruption constrains phage resistance evolution in A. baumannii. Compensatory mutation and bacterial metabolism not only mitigate fitness cost and maintain antimicrobial resistance but also expand evolutionary trajectories of bacteria under phage pressure. These findings reveal the adaptive mechanisms of colistin-resistant A. baumannii under phage selection and support the optimization of phage therapy.",

In this study, a segmented-flow tubular capillary biofilm reactor was investigated using a dual-species consortium of Pseudomonas taiwanensis and Rhodopseudomonas palustris for nitrogenase-driven hydrogen production. Biofilm development and biomass dispersion were monitored using a newly established flow cytometry-based analysis pipeline capable of quantifying the abundance of the different organisms in the reactor outflow. Mature biofilms operated under N2-limited conditions exhibited stable species composition and cell numbers over a 72\u202fh monitoring period, indicating semi-steady-state conditions characterized by slow growth and continuous erosive dispersion. Hydrogen production was strongly influenced by reactor gas composition. Unexpectedly, strictly anaerobic operation did not maximize hydrogen evolution. Instead, the addition of small amounts of O2 (\u22641\u202f%) significantly enhanced hydrogen production, likely by supporting the growth of the aerobic partner Pseudonomas taiwanensis, which stabilizes the biofilm structure and maintains favorable microoxic conditions. Hydrogen production declined in mature biofilms with high biomass accumulation, consistent with growth-coupled nitrogenase activity. To address this limitation, controlled biofilm dispersion was implemented by temporarily interrupting nutrient supply, inducing biofilm sloughing followed by rapid regrowth. This strategy restored high hydrogen production rates and enabled cyclical production phases while maintaining continuous reactor operation. Electron balance analysis further revealed substantial unaccounted electron fluxes, suggesting significant biofilm-associated maintenance energy demands. These results highlight the importance of biofilm management strategies for improving productivity and process control in biofilm-based production systems.",

This research examined the antibacterial mechanism and antivirulence efficacies of citral (CT), as a quorum sensing inhibitor (QSI), against S. putrefaciens and P. fluorescens in mono- and co-culture. Furthermore, the application of CT to large yellow croaker preservation was investigated. Results revealed that CT exerted its antibacterial activities in a dose-dependent manner. CT increased intracellular oxidative stress levels and malondialdehyde (MDA) content, decreased ATP content and peroxidase activity, and promoted the damage of cell membrane, especially in S. putrefaciens group. These two bacteria had a synergistic effect in causing spoilage through biofilm formation and motility. The antivirulence efficacies of CT against the co-culture group were weaker than those of in the mono-culture groups. CT was also found to suppress the expression of key virulence regulators in S. putrefaciens and P. fluorescens virulence, including Autoinducers-2 (AI-2) production in the QS system. Furthermore, CT had the potential capability in the preservation of large yellow croaker. Consequently, these results proved CT could combat bacteria and had antivirulence efficacies against S. putrefaciens and P. fluorescens in mono- and co-culture.",

A significant synergistic antibacterial effect was achieved with the fractional inhibitory concentration index being 0.5 when the two agents were combined at their respective 1/4 of minimum inhibitory concentration. Mechanistic studies revealed that the combined treatment severely disrupted bacterial membrane integrity and potential, inhibited biofilm formation, and caused extensive cell lysis in P. fluorescens PF08. Fourier transform infrared spectroscopy further indicated that the combined treatment caused the most severe damage to cell wall peptidoglycan, proteins, and polysaccharides. Non-targeted metabolomics disclosed that SAEW primarily disturbed histidine and lysine metabolisms, while \u03b5-PLH interfered with arginine and glutathione metabolisms, and their combination triggered broader metabolic reprogramming in the strain, demonstrating a multi-target antibacterial mechanism. This study provides a theoretical basis for the application of the SAEW-\u03b5-PLH composite green antibacterial agent in the preservation of aquatic raw materials and their prefabricated meal products which is perishable due to contamination by P. fluorescens.",

However, the specific roles of LRR-only proteins in pathogen-specific resistance remain largely unclear. Here, we show that allelic variations in an Arabidopsis thaliana LRR-only gene, LEUCINE-RICH REPEAT IMMUNE PROTEIN 1 (LRIP1), underlies dual functions in combating distinct pathogens. An allele common in arid regions confers resistance to Pseudomonas syringae pv. tomato (Pst) bacteria via salicylic acid (SA) signaling pathway, whereas an allele enriched in high-precipitation regions protects against Botrytis cinerea fungus via camalexin biosynthesis. Divergence in promoter and coding sequences between the two alleles modulates gene expression and elicitor-associated immune responses, thereby promoting pathogen-specific complex formation with BRASSINOSTEROID INSENSITIVE 1 (BRI1)-ASSOCIATED RECEPTOR KINASE 1 (BAK1). Globally distributed A. thaliana accessions carry two distinct LRIP1 allele groups that correlate with local precipitation conditions. These findings demonstrate that a single LRR-only gene can evolve environmentally adapted alleles that optimize immunity against different pathogens in contrasting habitats.",

The widespread use and overuse of antibiotics have contributed to the rise of antibiotic-resistant bacterial strains. Thus, it becomes essential to find alternative therapeutic strategies that can both accelerate wound healing and provide potent bactericidal effects. Electrospun nanofiber scaffolds of polycaprolactone (PCL)/polyacrylonitrile (PAN) containing silver nanoparticles (AgNPs) and vancomycin (Van) (Van-Ag-PAN/PCL), chitosan (Cs)/gelatin (Gel)/polyethylene oxide (PEO) containing bioactive glass nanoparticles (BG) and ciprofloxacin (Cip) (Cip-BG-Cs/Gel/PEO) besides a bilayer nanofiber scaffold were fabricated and charachterized. Surface properties, antioxidant activity, and biocompatibility were evaluated using contact angle measurements, antioxidant assays, and hemolysis tests, respectively. The cytotoxicity of the fabricated nanofibers was assessed by MTT assay on the L929 fibroblast cell line. The antimicrobial effectiveness of the fabricated nanofibers against Methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa was investigated in vitro using disk diffusion methods, along with evaluations of biofilm formation inhibition and eradication capabilities.\u00a0The results demonstrated that the electrospun Cip-BG-Cs/Gel/PEO scaffold and bilayer scaffold significantly inhibited one-day biofilm formation of both bacterial strains compared to the control group. Regarding one-day biofilm removal, the Van-Ag-PAN/PCL, Cip-BG-Cs/Gel/PEO and bilayer scaffolds exhibited high efficiency, achieving 66.3%, 68% and 69.3% eradication in MRSA and 34%, 69%, and 70% eradication in P. aeruginosa, respectively. The scaffolds were biocompatible and showed no cytotoxicity on L929 fibroblast cells. Their high antioxidant activity and lack of hemolysis confirm the strong potential of these materials for biotechnological applications.\u00a0The study concludes that the fabricated nanofibers effectively inhibit bacterial biofilm formation by MRSA and P. aeruginosa. Their strong antibacterial properties suggest potential use in reducing hospital-acquired infections and in applications such as drug delivery, tissue regeneration, and wound dressings, due to their controlled and sustained release of bioactive compounds for improved therapeutic outcomes.",

Most of them were caused by pathogens like Campylobacter spp., Salmonella enterica, Escherichia coli, and Listeria monocytogenes. Due to the short shelf life of fresh meat and dairy products, a rapid detection of pathogens in contaminated food products is essential. Since reference methods for microbial food analysis require time-consuming nonselective and selective culturing procedures, the need for more efficient approaches is given. In this study, we employ superparamagnetic iron oxide nanoparticles (SPIONs) functionalized with the peptide KRQGRVEVLYRASWGTV derived from the salivary protein GP-340, to successfully remove different species of food-related microorganisms (Pseudomonas paracarnis, Campylobacter jejuni, Escherichia coli, Enterococcus faecalis, Salmonella enterica, and Listeria monocytogenes) from pure media and homogenates derived from retail meat products. We discovered differences in extraction efficiencies from pure culture ranging from 18% (C. jejuni) to complete extraction (E. faecalis, L. monocytogenes and P. paracarnis) depending on the organism. It was also shown that L. monocytogenes could successfully be removed from co-culture with a high surplus of non-pathogenic P. paracarnis, and also from food matrices.

        "42410210": "ID: 42410210\nTitle: Non-canonical gene amplifications facilitate adaptive evolution in bacteria.\nAbstract: Gene amplification, a common route to bacterial adaptation, often occurs through recombination between two copies of an insertion sequence (IS) element flanking a genomic region. Alternative non-canonical structures have also been proposed, in which a duplication is formed by a single IS element whose two ends join two distant chromosomal loci. However, the prevalence of such non-canonical structures and their role in bacterial adaptive evolution remain unclear. Here we developed AmpliFinder, a computational tool that uses short-read sequencing data to systematically identify pairs of IS-chromosome junctions that correspond to the two ends of the same IS element yet map to distant genomic loci flanking amplified regions. Applying AmpliFinder to 10,347 laboratory-evolved Escherichia coli and Acinetobacter baumannii isolates, we identified 113 distinct de novo IS-associated amplifications and found that non-canonical amplifications are the most abundant mode of amplification. We validated the inferred architectures using ultra-long-read sequencing and propose a model for non-canonical amplification formation supported by the observation of nested intermediate structures. Quantifying enrichment for antibiotic-resistance genes in amplicons, we find that non-canonical amplifications more effectively and narrowly amplify genes under selection. These results highlight the role of non-canonical IS-based amplifications in the adaptive evolution of bacteria.",

This study evaluated the distribution, resistance profiles, and associated factors of ESKAPE pathogens isolated in Somalia. This retrospective single-center laboratory-based study was conducted at Mogadishu Somalia T\u00fcrkiye Recep Tayyip Erdo\u011fan Training and Research Hospital, a tertiary care center in Mogadishu, Somalia. Only culture-positive clinical specimens yielding ESKAPE pathogens between January 2024 and December 2025 were included. A total of 2,486 ESKAPE isolates were analyzed. Antimicrobial susceptibility testing was performed using the Kirby-Bauer disk diffusion method according to CLSI criteria. Demographic and clinical data were analyzed using SPSS and R software. Associations between selected demographic and clinical factors and specific pathogens were evaluated using univariate binary logistic regression analysis. Of the isolates, 1,442/2,486 (58.0%) were obtained from male patients, and the most common age group was 18-40 years [952/2,486 (38.3%)]. The most prevalent pathogens were K. pneumoniae [1,033/2,486 (41.6%)] and S. aureus [629/2,486 (25.3%)]. Overall, MDR and XDR phenotypes were detected in 1,633/2,486 (65.7%) and 687/2,486 (27.6%) isolates, respectively. The highest MDR and XDR rates were observed in A. baumannii [135/138 (97.8%) and 97/138 (70.3%)]. High resistance to ceftazidime [128/138 (92.8%)], cefepime [116/138 (84.1%)], ciprofloxacin [115/138 (83.3%)], trimethoprim-sulfamethoxazole [121/138 (87.7%)], and carbapenems [99/138 (71.7%)] was detected in A. baumannii. Susceptibility to vancomycin and linezolid remained largely preserved among Gram-positive pathogens. A. baumannii and Enterobacter spp. were significantly associated with ICU admission, while gender-related differences were observed for P. aeruginosa and S. aureus. A high burden of antimicrobial resistance was observed among ESKAPE pathogens, particularly Gram-negative bacteria, with A. baumannii playing a central role. These findings provide important local surveillance data that may support empirical antibiotic selection, antimicrobial stewardship, and infection control strategies in Somalia.",

Endophytic bacteria represent a promising sustainable alternative for disease management, yet systematic exploration of their potential against Xcc in citrus leaves remains limited. To address this, we characterized the leaf endophytic microbiome from major citrus-growing regions in southern China via high-throughput sequencing, revealing significant differences in the endophytic bacterial community structure between symptomatic and asymptomatic citrus leaves, with a significantly elevated relative abundance of Proteobacteria and prominent enrichment of the genera Xanthomonas, Enterobacter, and Pseudomonas in symptomatic tissues. Furthermore, symptomatic leaves harbored significantly higher endophytic bacterial diversity than asymptomatic leaves from the same production region, and the Xanthomonas abundance in the samples was highly consistent with the actual field disease severity. From 519 bacterial isolates, four strains-A1 (Bacillus altitudinis), A3 (Bacillus velezensis), A6 (Pseudomonas parafulva), and A7 (Delftia tsuruhatensis) demonstrated strong in vitro and detached-leaf antagonism against Xcc. Strain-specific fermentation parameters were optimized, and all four strains were successfully formulated into wettable powders. In a field trial, these formulations achieved control efficacies ranging from 25.8% to 53.5%, with strain A1 showing the highest and most sustained activity.

Here, we investigated how four genetically and phenotypically distinct Pseudomonas aeruginosa strains respond to sub\u2011MIC copper (Cu) and gentamicin (GE) stress, individually and in combination (Cu\u2009+\u2009GE). Across all strains, Cu acted as the dominant envelope\u2011active stressor, increasing biofilm biomass and extracellular DNA (eDNA) release, suppressing twitching and swarming motility, reducing quorum\u2011sensing\u2011linked protease activity, and enhancing pyomelanin production. GE alone produced limited physiological changes but modulated Cu\u2011driven outputs during co\u2011exposure, including attenuation of Cu\u2011induced eDNA release and strain\u2011specific shifts in motility and pigmentation. Early transcriptional profiling revealed consistent Cu\u2011dependent repression of lasI and mvfR, induction of the metal\u2011responsive regulator czcR, and downregulation of oprD under Cu or Cu\u2009+\u2009GE, corresponding to reduced imipenem inhibition zones when Cu was present during susceptibility testing. Combined Cu\u2009+\u2009GE exposure produced non\u2011additive, emergent effects that diverged from single\u2011stressor responses and varied across strains. These findings demonstrate that sub\u2011inhibitory Cu creates an envelope\u2011centered regulatory landscape into which gentamicin\u2011derived signals are integrated, generating heterogeneous and context\u2011dependent phenotypes. This work underscores the importance of metal-antibiotic interactions in shaping bacterial adaptation and highlights limitations of single\u2011stressor models for predicting antimicrobial behavior in combination.",

Gram-negative microbes such as carbapenem-resistant Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae are becoming more resistant than ever. Traditional methods of treatment using antibiotics are ineffective because of the presence of several envelope layers, active efflux pumps, and biofilm production. In contrast, bacteriolytic therapy can exacerbate host immunopathology owing to systemic endotoxin release. Host-defense peptides are thus being explored for their ability to kill bacteria, neutralize lipopolysaccharide (LPS), and modulate innate immune responses in a single treatment; however, clinical use remains hindered by their low stability, high binding to serum proteins, and narrow therapeutic index. In this review, we will discuss the use of biomaterial platforms in the design of peptide-based therapeutics to not only increase their efficacy by reducing peptide clearance but also optimize the immunological environment in which these peptides operate. We will discuss the role of various characteristics, such as surface chemistry, mechanical stiffness, and protein corona, in influencing macrophage polarization and downstream signaling pathways. In addition, we point out a significant limitation within this area of research: many preclinical studies continue to use minimum inhibitory concentration and hemolysis values, which fail to account for the host-directed effects that make these approaches significant. For future progress in this realm, new endpoints are required, along with more clinically relevant animal models and a true incorporation of peptide design into biomaterials engineering.",

Probiotics, particularly the genus Lactobacilli, offer an effective, multifaceted strategy that targets biofilm-associated pathogens through competitive exclusion, secretion of antimicrobial metabolites, disruption of quorum sensing, enzymatic degradation of extracellular polymeric substances, and host immunomodulation. Studies demonstrate robust efficacy of probiotics against clinically challenging pathogens, including methicillin-resistant Staphylococcus aureus, multidrug-resistant Pseudomonas aeruginosa, Clostridioides difficile, Helicobacter pylori, and pathogenic Escherichia coli. Postbiotics, particularly cell-free supernatants and purified bacteriocins, offer standardized, shelf-life probiotic products. Notably, synergistic combinations with conventional antibiotics, phytochemicals, or bacteriophages enhance antimicrobial activity while enabling dose-reduction strategies to mitigate the development of resistance. However, compelling preclinical evidence, clinical translation remains constrained by the imperative for strain-specific characterization, methodologically robust randomized controlled trials, and comprehensive safety validation.

The DRF emphasizes that disease results from cumulative host injury arising from the interplay between microbial virulence and the host immune response, rather than from the pathogen alone. HPI has been described as a \"tug of war\" between a pathogen and a host; the DRF improves this analogy by grounding it in reality, as both excessive immune activation and insufficient pathogen clearance can lead to host damage and disease. Acinetobacter baumannii is a Gram-negative pathogen known for its extensive drug resistance and immunomodulatory capacities. The interaction among isolate-specific virulence traits, antimicrobial resistance mechanisms, and host immune status determines the pattern and extent of damage, illustrating central tenets of the DRF. Different A. baumannii isolates may therefore produce varied clinical outcomes across different host conditions, depending on the extent of damage they cause. This narrative review discusses A. baumannii infections from the perspective of the DRF, highlighting how applying the DRF can inform our current understanding of A. baumannii pathogenesis by assessing A. baumannii HPI. We also provide brief insights into how the DRF can inform future research and treatment strategies that integrate host and microbial factors to minimize overall damage and improve host outcomes. A. baumannii infections are difficult to treat and can result in outcomes ranging from asymptomatic colonization to fatal disease. This narrative review examines these differences through the Damage Response Framework (DRF) to improve understanding of A. baumannii infections. The DRF emphasizes that disease results not only from the microbe but also from the interaction between microbial factors and the body\u2019s immune response. When the total damage from the microbe and the immune response exceeds the body's ability to repair, hosts become sick. Hosts with weak immune responses can become very ill because their immune systems cannot control the infection effectively. Conversely, patients with strong immune responses can also become severely ill when their immune systems damage vital tissues and organs in an effort to eliminate the bacteria.

Acinetobacter baumannii is an opportunistic pathogen responsible for severe hospital-acquired infections, including bloodstream infections (BSIs). Although major epidemic clones and resistance mechanisms have been described, integrated analyses combining clinical features, patient outcomes and genomic characteristics of BSI isolates remain limited, particularly in China.Gap Statement. Comprehensive analyses integrating clinical outcomes, high-resolution genotyping, capsule locus diversity and their associations with mortality are still lacking.Aim. This study aimed to characterize the clinical characteristics and outcomes of patients with A. baumannii BSIs, as well as the phenotypic and genomic characteristics of the causative isolates. Specifically, we sought to identify high-risk clones and their association with 30-day mortality to improve diagnostic and therapeutic strategies.Methodology. A retrospective cohort study was conducted on 151\u2009cases of A. baumannii BSIs in a tertiary hospital in China. Isolates were analysed using whole-genome sequencing to determine sequence types (STs), capsule loci and resistance and virulence gene profiles.Results. The 151 isolates were classified into 11 different STs using the Pasteur MLST scheme, with ST2Pasteur predominating (88.1%). One isolate represented a novel Pasteur ST (ST2831Pasteur). Using the Oxford MLST scheme, 22 STs were identified, with ST195Oxford, ST208Oxford and ST540Oxford being the most common. Four novel Oxford STs (ST2457Oxford, ST2458Oxford, ST2459Oxford and ST2460Oxford) were identified. Twenty-three capsule locus (KL) types were detected, with KL3 being the most prevalent. Phylogenetic analysis showed clear clustering according to STs and KL types. The ST2Pasteur lineage was characterized by the presence of the OXA-23 gene and carbapenem resistance, as well as an expanded virulence gene repertoire, suggesting enhanced pathogenic potential. The overall 30-day mortality rate was 35.1%. Patients in the death group had shorter hospital stays, fewer surgical interventions and higher rates of complications, invasive procedures and intensive care unit admission. Certain clone combinations, including ST369Oxford-KL9, ST938Oxford-KL210 and ST195Oxford-KL3, were associated with higher mortality rates.Conclusion. ST369Oxford-KL9, ST938Oxford-KL210 and ST195Oxford-KL3 represent high-risk clones associated with A. baumannii BSIs. Early identification of ST and capsule type, alongside clinical risk stratification, may improve diagnosis and guide treatment strategies.",

In this work, we aim to develop biodegradable and biocompatible antimicrobial systems by combining the versatile bis-MPA dendritic skeleton with the antibacterial properties of Zn(II) and Cu(II) complexes. The resulting metallodendrimers were synthesized using scalable bis-MPA scaffolds and systematically evaluated for antibacterial activity, cytotoxicity, resistance development and bactericidal kinetics. The dendrimers exhibit broad-spectrum antibacterial efficacy at low micromolar concentrations, with minimum inhibitory concentration values as low as 0.4 \u03bcM, while maintaining over 70% viability in fibroblasts and keratinocytes and showing no hemolytic activity toward erythrocytes at bactericidal doses. Second-generation Cu(II) and Zn(II) bis-MPA dendrimers eradicated Bacillus subtilis within 24 h and suppressed Pseudomonas aeruginosa within 4 h, without detectable resistance emergence and with superior activity to ciprofloxacin in the latter. Overall, the combination of rapid antimicrobial action, favorable cytotoxicity profiles, strain-dependent resistance behavior, and scaffold versatility highlights bis-MPA metallodendrimers as promising candidates for next-generation antimicrobial therapies.",

The NLR Resistance to Pseudomonas syringae2 (RPS2) recognizes Avirulence protein interacting with RPS2 (AvrRpt2), a Pseudomonas effector that promotes virulence by proteolytically cleaving a membrane-tethered host protein, RPM1-interacting protein 4 (RIN4). RIN4 cleavage by AvrRpt2 also activates RPS2. A model in which RPS2 is activated by elimination of RIN4 is consistent with the ectopic activity of RPS2 in plants lacking RIN4 but does not explain the link between AvrRpt2's virulence activity and RPS2 activation. We found that non-membrane-tethered RIN4 derivatives are potent cytosolic activators of RPS2. Activation of RPS2 by these RIN4 derivatives, like AvrRpt2-induced activation, and unlike ectopic activation in the absence of RIN4, requires the defense signaling protein NON-RACE-SPECIFIC DISEASE RESISTANCE 1 (NDR1). Cleavage products of RIN4 produced by AvrRpt2 play contrasting roles in the activation of RPS2, with the membrane-tethered C-terminal fragment suppressing RPS2 and the non-membrane-tethered internal fragment, dependent on compatibility with the C-terminal fragment, overcoming its suppression of RPS2.",

This cross-sectional study evaluated the minimum inhibitory concentrations (MICs) of quinolones and carbapenems against the Acinetobacter calcoaceticus-baumannii (ACB) complex and Pseudomonas aeruginosa isolated from clinical specimens at the Nepal Armed Police Force Hospital, Balambu, Kathmandu, Nepal. These NFGNB were isolated and identified using standard microbiological methods. Quinolone- and carbapenem-resistant isolates, screened by disc diffusion, were tested for MICs of quinolones and carbapenems using broth microdilution. Statistical analyses were performed in SPSS v. 17.0. Ninety-two NFGNB were isolated, predominantly from urine (40.2%; 37/92). The MDR proportion was high in P. aeruginosa (85.7% [18/21] versus 80.28% [57/71]). The extensively drug-resistant (XDR) proportion was high in the ACB complex (14.1% [10/71] versus 4.8% [1/21]). The MIC50 in P. aeruginosa against norfloxacin and ofloxacin was \u22658 and \u22650.5 \u00b5g/mL, respectively. The MIC50 against ciprofloxacin in P. aeruginosa was \u22658 \u00b5g/mL, whereas it was \u226532 \u00b5g/mL in the ACB complex. MIC50 against levofloxacin was \u22650.5 \u00b5g/mL in P. aeruginosa, unlike the ACB complex (\u226516 \u00b5g/mL). The MIC50 for meropenem was lower in the ACB complex (\u22654 versus \u22658 \u00b5g/mL) than in P. aeruginosa, whereas both showed similar MIC90 (\u226564 \u00b5g/mL). ACB complex showed higher MIC50 against imipenem (\u22654 \u00b5g/mL) than P. aeruginosa (\u22650.125 \u00b5g/mL). Over three-fourths of the NFGNB infections were caused by the ACB complex, exhibiting high XDR rates and elevated MICs to quinolones and carbapenems, underscoring the need for strengthened antimicrobial stewardship.",

Hence, we developed a computational framework (TACTIC [transfer-learning and cross-species training to infer combination therapies]) to train ML models on data from multiple model bacteria. TACTIC was built using 2,965 drug interactions from 12 bacterial strains and outperformed traditional ML models in predicting drug interaction outcomes for species with limited training data. Upon analyzing \u223c600,000 predicted drug interactions across 18 pathogenic and commensal strains, we identified interactions that are selectively synergistic against Gram-negative and mycobacterial pathogens.

Early identification of high-risk patients is essential. The Pitt Bacteremia Score (PBS) is validated in bloodstream infections, but its role in non-bacteremic infections remains unclear. To evaluate the performance of the PBS in predicting mortality among patients with non-bacteremic MDRO infections and compare it with the quick Sequential Organ Failure Assessment (qSOFA) score and the Charlson Comorbidity Index (CCI). We conducted a 5-year retrospective study at a tertiary care center including adults (>18 years) admitted between December 2018 and December 2023 with confirmed non-bacteremic MDRO infections. Organisms included methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), carbapenem-resistant Pseudomonas aeruginosa (CRPA), carbapenem-resistant Enterobacterales (CRE), and carbapenem-resistant Acinetobacter baumannii (CRAB). Patients with bloodstream infection, colonization, ICU stay >48 hours, severe COVID-19, or terminal illness were excluded. Separate multivariable logistic regression models were constructed for PBS, qSOFA, and CCI. Discriminatory performance was assessed using receiver operating characteristic (ROC) curve analysis. Among 202 patients (mean age 62.1 \u00b1 18.3 years; 67.8% male), in-hospital mortality was 21.3%. In multivariable analyses, PBS (aOR 1.75, 95% CI 1.49-2.05; p<0.001) and qSOFA (aOR 11.46, 95% CI 5.37-24.47; p<0.001) remained independently associated with mortality, whereas CCI did not retain statistical significance after adjustment. Age remained an independent predictor in all models, while time to effective antimicrobial therapy was independently associated with mortality in the CCI model (aOR 0.62, 95% CI 0.47-0.81; p<0.001). PBS demonstrated excellent discriminatory performance (AUC 0.939, 95% CI 0.897-0.968), outperforming qSOFA (AUC 0.883) and CCI (AUC 0.696). PBS is a strong predictor of in-hospital mortality in patients with non-bacteremic MDRO infections and demonstrated superior discriminatory performance compared with qSOFA and CCI. These findings support its use as an early risk-stratification tool in this high-risk population.",

Nevertheless, the influence of trauma biomechanics on infection development and microbial community dynamics is poorly studied. This study aimed to assess how different injury mechanisms influence wound microbiota dynamics and susceptibility to FRI. In this prospective cohort study, we recruited 155 patients with Gustilo-Anderson type II, IIIA, or IIIB open fractures. Deep tissue samples were obtained from all patients during their initial surgical debridement. In a subset of 28 patients who developed FRI, a second sample was collected at the time of re-debridement. The samples were matched and stratified into four groups based on trauma mechanism and infection status: Pre-debridement sharp, Pre-debridement blunt, Infection sharp, and Infection blunt. Microbial profiling was conducted using 16S rDNA sequencing. The sample metadata was analyzed in QIIME2, from which diversity indices (alpha and beta) were computed. The taxonomic composition and abundance were assessed at the genus level, while patterned relationships between groups were visualized through heatmap clustering. Beta diversity analysis showed that Pre-debridement sharp group clustered closely with both infection groups, significantly diverging from the Pre-debridement blunt group (p\u202f<\u202f0.001). In terms of alpha diversity, the Pre-debridement sharp group exhibited the highest levels across richness, evenness (p\u202f<\u202f0.05), as well as phylogenetic breadth. Taxonomic profiling showed that sharp trauma wounds were initially enriched with potentially pathogenic genera such as Pseudomonas, Acinetobacter and Staphylococcus, while blunt trauma wounds were dominated by low virulence taxa, like Bacillus. Heatmap analysis confirmed that the microbial composition of sharp samples was similar to those from both infection groups, suggesting that sharp trauma wounds possess a diverse microbial community that resemble the architecture seen in FRI. While the overall infection rate did not differ between blunt and sharp trauma, the mechanism of injury significantly influenced early microbial colonization patterns and infection development pathways. These findings emphasize the importance of trauma-specific microbiota profiling in understanding and potentially guiding the prevention of FRI.",

Rarely, it might present with hyperleukocytosis, which closely resembles congenital leukemia and creates a diagnostic difficulty. A preterm male neonate born at 34 weeks' gestation with a birth weight of 1.8 kg was delivered to a 27-year-old G2, P1 woman in a nonconsanguineous marriage. The neonate developed respiratory distress shortly after birth. Laboratory evaluation revealed a total leukocyte count of 108 \u00d7 103/\u00b5L (108 \u00d7 109/L), raising concern for congenital leukemia. However, peripheral blood smear showed cytoplasmic vacuolation and toxic granules without any blast cells, and flow cytometry excluded malignancy and leukocyte adhesion deficiency. Blood culture grew Acinetobacter baumannii A diagnosis of sepsis-induced hyperleukocytosis was made. The leukocyte count normalized with broad-spectrum antibiotics, and the neonate recovered fully.

        "42414298": "ID: 42414298\nTitle: Role of starvation survival response mechanisms on ribosome integrity, antibiotic tolerances, and virulence of Pseudomonas aeruginosa biofilms.\nAbstract: Bacterial biofilms contain physiologically diverse subpopulations of cells, including cells that are nutrient stressed or dormant. We determined how two dormancy pathways, ribosome hibernation and the stringent response, contribute to the survival and antibiotic tolerance of Pseudomonas aeruginosa biofilms. Analyses of whole biofilms and single cells showed that these pathways have differing effects on biofilm cell physiology. Ribosome hibernation, mediated by hibernation promoting factor (HPF), is essential for optimal survival and resuscitation of starved biofilm cells. In the absence of HPF, starved cells progressively lose ribosome integrity. However, loss of HPF does not increase the sensitivity of P. aeruginosa biofilm cells to ciprofloxacin or tobramycin. In contrast, the stringent response, mediated by RelA and SpoT, is not required for viability or ribosome integrity in starved biofilm cells, but does affect biofilm antibiotic tolerance. In a plant model of biofilm infection, disruption of either ribosome hibernation or the stringent response reduced bacterial virulence. The results show that ribosome hibernation preserves ribosomal integrity necessary for recovery from starvation and for pathogenesis, while the stringent response is required for growth arrest, antibiotic tolerance, and pathogenesis. These two ribosome-mediated pathways play distinct yet complementary roles in regulating dormancy and persistence of P. aeruginosa biofilms.",

This study aims to identify universally conserved surface antigens through pangenome analysis, predict immunogenic epitopes using integrated machine learning, and computationally design and in silico characterize a self-assembling nanoparticle vaccine with dual adjuvants. A computational framework integrating pangenome analysis of 712 complete genomes, epitope prediction, and structural vaccinology was employed to design a multi-epitope nanoparticle vaccine candidate for experimental evaluation. Pangenome analysis identified 3894 core genes with 42 outer membrane proteins, prioritizing OmpA, BamA, and OmpW as antigen targets. Protein language models predicted conformational B-cell epitopes, while NetMHCpan-4.2 predicted T-cell epitopes across 125 HLA alleles. The final construct (AB-VAX-01, 289 amino acids) incorporates 15 epitopes fused with dual adjuvants (RS09 TLR4 and cGAMP STING agonists) and a foldon domain for nanoparticle assembly. Microsecond molecular dynamics simulations with replicates demonstrated stability with TLR4 and STING. Conservation analysis across all 712 genomes showed 96.2-100% epitope identity.

The reaction utilized methyl acetoacetate (1 mmol), substituted aromatic aldehydes (2 mmol), and substituted anilines (2 mmol) at 60\u00a0\u00b0C to afford the desired compounds. All compounds were evaluated for their in vitro antimicrobial activity against three fungal strains (Candida albicans, Aspergillus niger, and Aspergillus clavatus), two Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa), and two Gram-positive bacteria (Staphylococcus aureus and Streptococcus pyogenes), using the serial broth dilution method. Additionally, their antimalarial potential was assessed against chloroquine- and quinine-sensitive 3D7 and multidrug-resistant Dd2 strains of Plasmodium falciparum.

To perform this assessment, clinical isolates of MDR Pseudomonas aeruginosa, Acinetobacter sp., Klebsiella sp., and methicillin-resistant Staphylococcus aureus (MRSA) were aerosolized to simulate realistic airborne transmission and subsequently introduced into the EBI system. Downstream bacterial aerosols were collected using liquid impingers and quantified by culture-based enumeration. CFU data were log\u2081\u2080-transformed prior to analysis. The EBI system reduced airborne bacterial loads by 4.01 log\u2081\u2080 for P. aeruginosa, 3.64 log\u2081\u2080 for Acinetobacter sp., 3.64 log\u2081\u2080 for Klebsiella sp., and 5.37 log\u2081\u2080 for MRSA, corresponding to disinfection efficiencies of 99.98-99.999%. Scanning electron microscopy (SEM) and elemental mechanistic study revealed morphological damage, including membrane rupture, surface collapse, and loss of structural integrity, suggesting that electron impact and electroporation may be major mechanisms of inactivation.

To address the substantial gap in antimicrobial resistance (AMR) data, the American University of Beirut Medical Center (AUBMC) investigated carbapenem-resistant Enterobacterales (CRE), Acinetobacter baumannii (CRAB), and Pseudomonas aeruginosa (CRPA). Consecutive, hospitalized patients whose clinical cultures were positive for CRE, CRAB, or CRPA were prospectively enrolled between June 2018 and November 2019. Data on demographics, hospitalization, outcomes, and antimicrobial susceptibility were collected. Whole-genome sequencing (WGS) characterized the isolates. The primary outcome was the Desirability of Outcome Ranking (DOOR). Ninety-four patients were included: 35 with CRE, 19 with CRAB, and 40 with CRPA. Overall, 30% of patients survived without adverse events, whereas 33% experienced two or more adverse events. Patients with CRAB had the poorest prognosis, with only 5% surviving without complications, and a significantly different DOOR distribution versus CRE or CRPA (p\u2009=\u20090.023). Adjusted DOOR probabilities confirmed the poorer outcomes associated with CRAB: when compared with CRE or CRPA, a randomly selected CRAB patient had only a 37.7% (95% CI, 24.9-52.6%) and 38.8% (95% CI, 26.5-52.7%) probability of achieving a more desirable outcome, respectively.

Given the rising prevalence of multidrug-resistant (MDR) Pseudomonas aeruginosa alternative therapeutic strategies are essential. This study synthesized and characterized artemisinin-loaded micelle/liposome nanoparticles (Art/PEG400-OA NPs) and evaluated their antibacterial, antibiofilm, and anticancer efficacy. Artemisinin was successfully encapsulated within PEG400-OA NPs and characterized via FT-IR, FE-SEM, TEM, TGA, and zeta potential measurements. The nanoparticles exhibited uniform morphology, particle sizes of 40.8\u00a0nm (TEM) and 149.8\u00a0nm (FE-SEM), high encapsulation efficiency (92.14%), and strong thermal and colloidal stability. Synergistic and partial synergistic interactions between Art/PEG400-OA NPs and ciprofloxacin were observed in MDR bacterial samples, significantly inhibiting biofilm formation. Quantitative RT-PCR analysis revealed the downregulation of efflux pump genes (mexA, mexB, mexX, mexY, oprM) and biofilm-associated genes (algD, pelA) following combination therapy. In AGS gastric cancer cells, Art/PEG400-OA NPs induced dose- and time-dependent cytotoxicity (IC\u2085\u2080: 67.75, 62.25 and 54.98\u00a0\u00b5g/mL at 24, 48 and 72\u00a0h), increased apoptosis (31.76% \u00b1 4.2%), and reduced wound-healing migration (56.65% \u00b1 4.26%). Expression analysis demonstrated upregulation of tumor-suppressive miR-34a, and downregulation of its targets (CTNNB1, TGFB1, MMP2 and MMP9). Conversely, miR-181a was downregulated, leading to the upregulation of apoptotic target genes (TP53, CASP8, CASP9). Molecular docking supported strong artemisinin binding to key bacterial and oncogenic proteins.

Automated identification using the VITEK-2 Compact system and confirmation at ICMR-NIRBI (Indian Council of Medical Research-National Institute for Research in Bacterial Infections), Kolkata, identified the isolate as Comamonas testosteroni. The organism was sensitive to piperacillin/tazobactam, ceftriaxone, cefoperazone/sulbactam, imipenem, meropenem, amikacin, gentamicin, ciprofloxacin, and trimethoprim/sulfamethoxazole. The patient responded well to ceftriaxone and supportive care. This case underscores the diagnostic challenge of detecting C. testosteroni, particularly during overlapping outbreaks. The inclusion of differential media and careful interpretation of culture results is crucial for accurate identification. Diligent culture reporting helps in strengthening public health surveillance, infection control, and outbreak preparedness in resource-limited settings.",

This study reports an outbreak of urinary tract infections associated with Pseudomonas aeruginosa (PA) in patients who underwent stone removal surgery using flexible ureteroscopy (FURS) at Seoul Medical Center. Between August and December 2024, five patients who underwent FURS performed by the same surgeon developed postoperative febrile episodes requiring further treatment. Urine cultures from four patients revealed an outbreak of multidrug-resistant PA, prompting environmental cultures and an inspection of the instrument reprocessing procedures led by the hospital's infection control department. Although PA was not isolated from the FURS itself, urine culture results showed identical antibiotic susceptibility profiles, and three patients exhibited temporal continuity, suggesting that the infections were related to surgery. No PA infections occurred among patients treated by other surgeons using single-use FURS during the same period, indicating that the infections were associated with the reusable FURS used solely by surgeon A. Environmental culturing detected PA on the sink and handle in the cleaning room, and deficiencies in the reprocessing procedures were identified. The FURS reprocessing protocol was revised to include ethylene oxide gas sterilization after each use, twice-daily disinfections of the sink where PA was identified, and replacement of handles and brushes. After implementing improvements to the reprocessing protocol, no further infections were reported over six months. Comprehensive device management may help prevent device related outbreaks. Given the complexity of FURS reprocessing, systematic management by trained personnel and ongoing monitoring are necessary to prevent device-associated infections.",

Large-scale extraction and isolation on the Australian-sourced lichen Parmotrema tinctorum resulted in the purification of \u22481 g of the desired scaffold 1, along with other known lichen metabolites that included divaricatic acid (2), orcinol (3), orsellinic acid (4), and methyl orsellinate (5). Parallel solution-phase synthesis using amidation chemistry on the abundant scaffold 1 afforded a series of novel amide derivatives 6-13 in high purity (>95%) and low to moderate yields (12-53%). All new semisynthetic compounds were fully characterised following 1D/2D NMR, MS and UV data analysis. Crystalline lecanoric acid was obtained during the chemical investigations of the lichen extract, enabling the first X-ray crystallographic analysis to be undertaken on this depside. Compounds 1-13 were evaluated for antibacterial activity against the human pathogen Pseudomonas aeruginosa using a biofilm inhibition assay. Of the new semisynthetics, amide analogue 12 showed the greatest planktonic cell growth inhibition (13% at 50 \u00b5M), whilst amide analogue 11 was the most active at inhibiting the formation of biofilm (21% at 50 \u00b5M).",

Resistance of nosocomial Gram-negative strains to carbapenems is a significant problem with a tendency to progress, necessitating close attention to it. Analysis of the prevalence of carbapenem-resistant flora in a urology clinic, identifying the most significant factors associated with the resistance of pathogens to medications. A single-center retrospective study was conducted analyzing 1,720 urine culture results from patients with nephrolithiasis managed at a tertiary care institution in Moscow. Acquired carbapenem resistance to at least one carbapenem was detected in 5.4% of patients. Carbapenem-resistant Klebsiella pneumoniae (70% of all carbapenem-resistant isolates) and Pseudomonas aeruginosa (13%) were the most frequently identified species. Male sex and age >50 years were identified as significant risk factors. A logistic regression model was constructed to quantify the contribution of major risk factors, demonstrating an area under the receiver operating characteristic curve (ROC-AUC) of 0.88. The relatively high prevalence of carbapenem-resistant Gram-negative urinary tract infection among patients hospitalized for urological management of nephrolithiasis necessitates further research to identify optimal therapeutic strategies and prevent postoperative infectious complications caused by these pathogens. Moreover, the prevalence rate of carbapenem-resistant bacteria (5.4%) carries important implications for antimicrobial stewardship and pharmaceutical resource allocation in urological inpatient settings.",

One of the key contributors to recurrent urinary tract infections is inappropriate therapy that does not take into account the local microbial spectrum and pathogen resistance profiles. To determine the spectrum of uropathogens and their antimicrobial resistance patterns in patients with cystitis, pyelonephritis, and prostatitis. We analyzed the results of microbiological urine cultures from outpatient urology patients processed by the Invitro Laboratory between 2022 and 2024. In total, 4031 bacterial isolates were included: 2903 (72.0%) from patients with cystitis, 1017 (25.2%) from patients with pyelonephritis, and 111 (2.8%) from patients with chronic prostatitis. The structure of the microbial landscape differed by diagnosis. E. coli was the predominant pathogen in all groups, with a detection rate of 73.8-75.3% in cystitis and pyelonephritis, while in chronic prostatitis the rate was markedly lower at 53.1%. Klebsiella pneumoniae and Enterococcus faecalis were more frequently isolated in prostatitis (19.0% and 15.3%, respectively) compared with urinary infections, where their combined frequency ranged from 6.9% to 11.9%. Other pathogens (Proteus mirabilis, Streptococcus agalactiae, Enterobacter cloacae, Pseudomonas aeruginosa) accounted for 6.4% of isolates in cystitis, 7.6% in pyelonephritis, and 12.6% in prostatitis. Antimicrobial resistance was assessed for E.coli isolates. Resistance to amoxicillin/clavulanate was 24.9% in cystitis, 31.0% in pyelonephritis, and 38.9% in prostatitis. Levofloxacin resistance was observed in approximately one third of isolates from cystitis and in about half of isolates from pyelonephritis, whereas all E.coli isolates from prostatitis cases were susceptible. Resistance to trimethoprim-sulfamethoxazole in prostatitis was approximately twice as high as in cystitis and pyelonephritis. Urinary tract infections are predominantly caused by E.coli, while chronic prostatitis is associated with a more diverse spectrum of pathogens, with E.coli detected in only 53.1% of cases. Antimicrobial resistance profiles differ substantially between urinary infections and prostatitis, underscoring the importance of tailoring empirical therapy to local pathogen distribution and resistance patterns.",

A total of 3,746 blood culture samples were collected from patients with suspected septicemia and samples were processed using the BACTEC blood culture system, and all positive cultures were sub-cultured onto blood agar and MacConkey agar plates for isolation. Bacterial identification and antimicrobial susceptibility testing were performed using the VITEK 2 compact system following CLSI guidelines. Detection of antimicrobial resistance genes was carried out by PCR using gene-specific primers. Of 3,746 blood cultures, 873 (23.3%) were positive, yielding 577 (66.1%) Gram-negative isolates. Among these, 212 (24.3%) were CR-GNB, predominantly A. baumannii (41.5%), and K. pneumoniae (21.2%). MIC of meropenem among CR-GNB isolates ranged from >128 \u00b5g/mL to <1024 \u00b5g/ml.

There was a high prevalence of CR-GNB among septicemia patients, emphasizing the need for strict infection control measures to prevent their spread. Sepsis, or blood infection, is a serious and life-threatening condition that can affect people of all ages. In recent years, many of these infections have become harder to treat because some bacteria no longer respond to life-saving antibiotics called carbapenems. These bacteria are known as carbapenem-resistant Gram-negative bacteria and are listed by the World Health Organization as \u201cpriority pathogens.\u201d In Pakistan, infections caused by these resistant bacteria are increasing, but there is limited information about how common they are and what types of resistance they carry.

However, its impact on rice microbiomes remains poorly understood. This study evaluated the microbiota of two rice ecotypes, low-amylose (Mochi) and high-amylose (BRS Formoso), after germination and polishing using 16S rRNA and ITS amplicon sequencing. Bacterial alpha diversity was highest in commercial brown rice (Shannon index 3.21) and lowest in commercial polished rice (1.50). Beta diversity indicated that germination exerted a similar effect on bacterial community composition in both ecotypes. Principal Coordinate Analysis suggested that polishing did not markedly influence microbiome composition relative to germination. The microbial profiles of Mochi and BRS Formoso were dominated by Pantoea, Pseudomonas, Rhizopus, and Moesziomyces. Overall, germination strongly influenced bacterial and fungal communities, emerging as the main factor shaping microbial structure and dynamics. These findings provide new insights into how processing affects the rice microbiome, with implications for food quality and safety.",

Perfluorooctyl bromide (PFOB) has demonstrated in-vitro bacteriostatic activity against Pseudomonas aeruginosa, but it is unknown whether this effect is maintained when PFOB is emulsified (PFOBe). This study aimed to evaluate the effect of PFOBe on the growth of antibiotic-resistant strains of P. aeruginosa, Staphylococcus aureus, and Klebsiella pneumoniae. Time-kill assays were performed to evaluate the activity of meropenem, gentamicin, oxacillin, PFOBe, and antibiotic-PFOBe combinations against resistant strains (K. pneumoniae ATCC BAA-2814, P. aeruginosa CeMoP 501, and S. aureus ATCC 33591) and antibiotic-susceptible strains (K. pneumoniae ATCC 700603, P. aeruginosa ATCC 27853, and S. aureus ATCC 25923). Morphological changes were assessed using scanning electron microscopy. PFOBe showed bacteriostatic activity against all tested strains and a limited enhancement of the antibiotics when combined. Structural alterations in bacterial cell walls were observed depending on the strain and treatment combination. PFOBe exhibits bacteriostatic activity and enhances against both resistant and susceptible bacterial strains, suggesting its potential as an adjuvant antimicrobial strategy.",

This review examines how host-derived factors modulate QS-linked virulence in enteric pathogens, Pseudomonas aeruginosa and Staphylococcus aureus. Across these systems, host control operates through three recurring modes: activation or signal mimicry, enzymatic signal degradation, and extracellular sequestration or receptor-level interference. Catecholamines and related metabolites can feed into bacterial sensory pathways and promote virulence signaling; PONs (paraoxonases) and other host enzymes can degrade autoinducers; and lipoproteins, immune mediators, and epithelial surveillance systems can intercept or reinterpret quorum signals. Together, these data support the view that the host is an active signal-processing environment that reshapes colonization, persistence, and tissue damage, and they point to host-inspired anti-virulence strategies that target signaling rather than viability.",

Conventional microbiological methods may underestimate resistance determinants and transmission dynamics. Long-read metagenomic sequencing is a promising approach for Pathogen detection, resistome characterization, and genomic surveillance. The study's objectives were to characterize the resistome, including detection of the blaVIM gene, assess genomic relatedness and potential transmission dynamics, and evaluate the diagnostic value of metagenomics compared with conventional microbiological approaches. This retrospective infection control investigation included seven hospitalized patients from multiple hospital units. Clinical specimens included blood, respiratory specimens, surgical tissue, and device-associated material. Conventional microbiological investigations included bacterial culture, identification, and antimicrobial susceptibility testing (AST) using the VITEK 2 automated system. Carbapenemase genes were detected using Xpert Carba-R. Long-read metagenomic sequencing was conducted using Oxford Nanopore Technologies (ONT) on the GridION platform. Bioinformatic analysis was performed using the CosmosID platform for taxonomic profiling, antimicrobial resistance gene detection, and genomic relatedness assessment. Conventional microbiological methods identified carbapenem-resistant Pseudomonas aeruginosa (CRPA) in five cases, whereas ONT sequencing detected the blaVIM gene in all seven samples, demonstrating superior diagnostic sensitivity. A highly conserved resistome profile was identified across all investigated cases, including multiple \u03b2-lactamase and aminoglycoside, fluoroquinolone, and polymyxin-associated resistance determinants. Genomic relatedness analysis demonstrated close clustering patterns with minimal genomic variability, suggesting possible circulation of closely related MDR strains. These findings highlight the added value of ONT sequencing in identifying concealed resistance determinants and improving transmission tracking compared with conventional diagnostic approaches. Future investigations involving larger sample sizes and environmental surveillance are needed to further clarify transmission dynamics and potential reservoirs of VIM-producing P. aeruginosa.",

This study aimed to identify candidate protein targets for fungicide development in P. graminis f. sp. tritici. An integrated subtractive proteomics pipeline was then applied, combining essentiality screening, pathway analysis, structural modeling, and exploratory molecular docking. A stringent filtering strategy excluding proteins homologous to Triticum aestivum, Homo sapiens, and beneficial microbes (Bacillus subtilis, Pseudomonas fluorescens, and Trichoderma harzianum) was applied, thereby maximizing selectivity while minimizing potential off-target ecological effects. From 36,348 proteins, four putative targets were identified: two \u03b2-glucan synthesis-associated KRE6 homologs, a cell wall \u03b1-1,3-glucan synthase (AGS1), and a Major Facilitator Superfamily (MFS) transporter. Guided by intrinsic disorder analysis, AlphaFold2 was used to generate high-quality 3D structural models of the prioritized targets. Network-based functional analysis linked these proteins to core cellular processes, while underscoring that their essentiality in P. graminis f. sp. tritici remains experimentally unconfirmed. Molecular docking with the antifungal agent poacic acid and the nucleotide sugar UDP-glucose suggested potential binding interactions within the predicted cavities. These exploratory simulations present preliminary evidence for plausible small-molecule binding pockets in the selected candidate targets. Collectively, this work provides a multi-layered computational framework for nominating and structurally characterizing candidate targets in wheat stem rust and generates testable hypotheses for future experimental work.",

Despite growing interest in its pharmacological properties, studies integrating nanoparticle biosynthesis, comprehensive biological evaluation, and computational analysis remain scarce for its austriacum subspecies. In this study, magnesium nanoparticles (VA-MgNPs) were green-synthesized using the ethanol extract of Viscum album subsp. austriacum as a bioreducing and capping agent, and their biological activities were comparatively assessed alongside the crude extract and Mg(NO3)2\u00b76H2O precursor control. LC-HR/MS analysis identified quinic acid (10,027.49\u202f\u03bcg/g) and chlorogenic acid (5294.12\u202f\u03bcg/g) as the dominant phenolic constituents. The synthesized VA-MgNPs were characterized by FT-IR, UV-Vis, FE-SEM, TEM, and XRD analyses, confirming nanocrystalline formation with a mean crystallite size of approximately 66.47\u202fnm. Antioxidant evaluation using DPPH, ABTS, and FRAP assays revealed that the crude extract retained superior radical scavenging capacity, which is attributed to the consumption of free phenolic hydroxyl groups during nanoparticle formation. In contrast, VA-MgNPs demonstrated markedly enhanced anticancer activity against breast (MCF-7: IC50\u202f=\u202f124\u202f\u03bcg/mL; MDA-MB-231: IC50\u202f=\u202f96\u202f\u03bcg/mL) and colorectal (HCT116: IC50\u202f=\u202f105\u202f\u03bcg/mL; HT-29: IC50\u202f=\u202f135\u202f\u03bcg/mL) cancer cell lines, with lower cytotoxicity toward non-tumorigenic cells, indicating selective antiproliferative action. Although antibacterial activity was limited across tested strains, VA-MgNPs exhibited significant antibiofilm activity, achieving up to 75% inhibition against Pseudomonas aeruginosa. Molecular docking simulations revealed that chlorogenic acid and its magnesium complex displayed strong binding affinities toward antioxidant- and antimicrobial-related protein targets, with binding energies reaching -8.5\u202fkcal/mol, mechanistically supporting the observed biological activities. These findings demonstrate that VA-MgNPs are a promising nanotherapy platform, particularly for antibiofilm and anticancer applications.",

Forty-three CRPA isolates were collected from sterile clinical specimens in the Republic of Korea (ROK) between 2015 and 2025. Susceptibility to 14 antibiotics was assessed in vitro by broth microdilution. Carbapenem-resistance mechanisms were characterized by using polymerase chain reaction (PCR), real-time quantitative reverse transcription PCR (RT-qPCR), and sequencing. Clonal diversity and epidemiological trends were examined by multilocus sequence typing (MLST). Among the 43 CRPA isolates, the susceptibility rates were 88.4% for both aztreonam-avibactam and cefiderocol, compared with 46.5% for ceftolozane-tazobactam and 39.5% for ceftazidime-avibactam. Among the 22 difficult-to-treat resistance (DTR) P. aeruginosa isolates, susceptibility rates were 77.3% for aztreonam-avibactam and 86.4% for cefiderocol. Carbapenemase genes were detected in 46.5% of isolates, predominantly blaNDM (41.9%). Porin loss and efflux pump overexpression were observed in 83.7% and 23.3% of isolates, respectively.

Carbapenem resistance may arise through chromosomal mutations, acquisition of resistance genes, and clonal dissemination under sustained antimicrobial pressure. To investigate the temporal dynamics of carbapenem resistance in clinical P. aeruginosa isolates from a tertiary-care hospital in Valpara\u00edso, Chile, and to assess their association with antimicrobial consumption. Forty-five clinical isolates recovered between 2019-2024 were analyzed. Antimicrobial susceptibility testing, phenotypic and molecular carbapenemase detection, motility and biofilm assays, and whole-genome sequencing were performed. Sequence types, resistome, virulome, and chromosomal mutations associated with resistance were characterized. Antimicrobial consumption data from the local stewardship programme were evaluated using temporal trend and cross-correlation analyses. Carbapenem non-susceptibility was frequent, and extensively drug-resistant isolates predominated during the pandemic and post-pandemic periods. Resistance was mainly associated with non-carbapenemase-producing isolates and was linked to mutations in oprD, regulators of the MexAB-OprM efflux system, and ampC-related pathways, together with intrinsic OXA-50-like-\u03b2-lactamases. The blaVIM-2 gene was identified in ST408, ST815, and ST253. Temporal clonal turnover was observed, with ST309 emerging as the dominant lineage in 2023-2024. The acquired resistome diversified over time, whereas the virulome remained largely conserved. Higher antimicrobial consumption in intensive care units was associated with carbapenem resistance. Sustained antimicrobial pressure likely contributed to the persistence and replacement of carbapenem-resistant lineages. Integrating genomic surveillance with antimicrobial stewardship may improve detection and control of high-risk hospital clones.",

Studies of temperature-AMR associations remain limited by geographic scope, time frames and linear approaches. We aimed to identify temperature thresholds where AMR dynamics shift across pathogen-drug combinations, periods and socioeconomic contexts. We analysed data from 56 countries and territories over 24 years (1999-2022), focusing on six WHO-designated 'critical' antibiotic-resistant pathogens. Using segmented regression models with mean ambient temperature as the primary independent variable, we divided the study period into three intervals (1999-2006, 2007-2014, 2015-2022)\u2009and incorporated 16 socioeconomic and environmental covariates. Model robustness was validated through bootstrap cross-validation with 1000 resamples. We identified distinct temperature association thresholds for each pathogen-drug combination (5.7\u00b0C-18.4\u00b0C). Below these thresholds, resistance rates consistently decreased with rising temperatures; above thresholds, responses varied by phenotype and time period. For third-generation cephalosporin-resistant Escherichia coli, each 1\u00b0C rise above 16.5\u00b0C corresponded to a 0.46% increase (95%\u2009CI 0.28% to 0.65%; p<0.001) during 1999-2006, a 0.11% decrease (95%\u2009CI -0.17% to -0.06%; p<0.001) during 2007-2014 and a 0.18% increase (95%\u2009CI 0.11% to 0.25%; p<0.001) during 2015-2022. The Corruption Perception Index showed consistent negative associations with resistance rates, particularly for carbapenem-resistant Acinetobacter baumannii (\u03b2=-1.40, p<0.001). Phenotype-specific temperature association thresholds provide descriptive, hypothesis-generating reference points for understanding how AMR burden varies along the global temperature gradient. The observed temporal heterogeneity suggests complex patterns requiring long-term monitoring and climate-adaptive AMR control strategies considering both phenotype-specific temperature sensitivities and socioeconomic contexts.",

Here, we identify a persistence mechanism mediated by pyruvate secretion resulting from mutations in the pyruvate dehydrogenase complex in clinical isolates of P. aeruginosa, with putative analogous mutations also identified in Staphylococcus aureus, Haemophilus influenzae and Stenotrophomonas maltophilia. These mutations lead to elevated extracellular pyruvate, which dampens host inflammatory responses and favors bacterial persistence. Pyruvate exerts multiple roles: scavenges reactive oxygen species such as H2O2, suppresses host immune activation both in airway epithelial cells and macrophages, and increases bacterial survival during phagocytosis. This metabolic crosstalk promotes bacterial persistence while reducing epithelial and macrophage inflammatory responses. Our findings reveal pyruvate as a bacterial immunometabolite that mimics host antioxidant defenses, reshaping the infection niche to favor long-term colonization. This work highlights the broader role of secreted metabolites in host-pathogen interactions and suggests new strategies targeting metabolic pathways to manage chronic infections.",

Here, we report a pulmonary mRNA-lipid nanoparticle (mRNA-LNP) vaccine incorporating an ionizable lipid engineered for localized high-level expression, which elicits both rapid and durable protection against bacterial lung infections in female mice, effectively bridging this critical window of vulnerability. Intratracheal delivery of mRNA-LNP rapidly primes lung neutrophils and macrophages into a transcriptionally pre-activated state, enhancing their phagocytic activity and enabling rapid, antigen-independent bacterial clearance during the early post-vaccination period (approximately 1-7 days). Subsequently, vaccination induces potent antigen-specific adaptive responses, conferring sustained protection against both laboratory and clinical drug-resistant Pseudomonas aeruginosa strains. Single-cell transcriptomics and immune profiling reveal coordinated activation of innate and adaptive immune programs. This dual-phase immune response exemplifies a paradigm-shifting vaccine design that integrates innate and adaptive immunity to confer both immediate and long-term protection. Our findings establish a mechanistic basis for rapid antibacterial defense and highlight pulmonary mRNA-LNP vaccination as a promising strategy for combating respiratory infections.",

These gram-negative bacteria often cause healthcare-associated infections (HAIs), which pose an increasing threat to public health. This study aimed to isolate and identify CRPAs and CRABs from a tertiary care hospital in central Nepal and characterize carbapenem resistance genes at the molecular level. A total of 59 isolates, including 27 Pseudomonas aeruginosa and 32 Acinetobacter baumannii, were collected from different clinical samples from April 2021 to December 2022. Antibiotic susceptibility was determined via the Kirby disc diffusion method. The modified carbapenem inactivation method (mCIM) was used for phenotypic confirmation of carbapenem resistance. Conventional polymerase chain reaction (PCR) was used to detect carbapenem resistance genes. Among the 59 isolates, 76.3% were multidrug resistant (MDR), 63.0% were extended-spectrum beta-lactamase (ESBL), and 62.7% were carbapenem resistant. Among the carbapenem-resistant isolates (n\u2009=\u200937), 75.7% of metallo-beta-lactamase (MBL) producers and 70.3% carried at least one carbapenem resistance gene. The blaCTX-M gene was predominant among the ESBL-positive isolates, present in 58.8% of the P. aeruginosa isolates and 87.5% of the A. baumannii isolates, whereas 29% of both isolates harbored the blaTEM gene. Among the CR-PA isolates, 58.3% carried blaVIM-2, 16.7% carried blaNDM-1, and 8.33% carried blaOXA-23. Among the CR-AB isolates, 56% harbored blaOXA-23, 32% carried blaNDM-1, 16% had both blaNDM-1 and blaOXA-23, and 8% contained both blaOXA-58 and blaOXA-23. This study highlights a significant burden of MDR and carbapenem-resistant P. aeruginosa and A. baumannii, with the co-occurrence of carbapenem resistance genes, in a clinical setting in Nepal. Our findings suggest that active surveillance of antibiotic resistance in pathogens could inform clinicians and healthcare providers about the treatment of infections.",

This unit harbors multidrug-resistant organisms, thereby complicating the management of infectious diseases within clinical settings, particularly in resource-limited countries. This study, therefore, aimed to determine the occurrence and antimicrobial resistance profiles of bacteria, including Extended-spectrum beta-lactamase- and Carbapenemase-producing isolates, in the intensive care units of two hospitals in Addis Ababa, Ethiopia. A repeated cross-sectional study was conducted in Addis Ababa, Ethiopia, from July 2024 to April 2025. A total of 239 swab samples were collected from adult and neonatal intensive care unit environments during both the dry and rainy seasons. Samples were collected and processed aseptically. Bacterial identification and antimicrobial susceptibility testing were performed according to CLSI guidelines. From the total samples collected, 162/239 (67.8%) bacterial isolates were recovered from the Intensive Care Unit environment. Klebsiella pneumoniae 22/162 (13.6%) and Pseudomonas aeruginosa 21/162 (13%) were the most frequently isolated bacterial species. All P. aeruginosa were resistant to ceftazidime, while 19/22 (86.3%) and 18/22 (81.8%) of K. pneumoniae were resistant to cefuroxime and cefotaxime, respectively. All S.haemolyticus were also resistant to penicillin, and 8/12 (66.7%) of Enterococcus spp were resistant to erythromycin. Multidrug-resistant bacteria were seen in 89/150 (59.3%) of isolates. The highest multidrug resistance rate was obtained for Pseudomonas aeruginosa 18/21 (85.7%), followed by Klebsiella pneumoniae 16/22 (72.7%) and Acinetobacter spp 8/11 (72.7%). Extended-spectrum \u03b2-lactamase-producing isolates accounted for 23/105 (21.9%), and Carbapenemase-producers comprised 10/105 (9.5%). The environments within intensive care units are conducive to the proliferation of multidrug-resistant microorganisms, encompassing bacterial isolates that produce extended-spectrum beta-lactamases and carbapenemases, thereby complicating the management of infectious diseases. Consequently, it is crucial to address the issue of antimicrobial resistance in this critical setting to mitigate the incidence and dissemination of resistant bacteria, which may lead to the emergence of nosocomial infections.",

Strain J68 was identified using MALDI-TOF MS and average nucleotide identity (ANI) analysis. Antimicrobial susceptibility was determined by broth microdilution method. PCR screening, conjugation assay and whole-genome sequencing were performed to characterize the strain J68. The strain J68 was identified as P. asiatica, it exhibited resistance to multiple antibiotics, including tigecycline and carbapenem. Subsequent analysis revealed that 24 antimicrobial resistance genes, including the tigecycline resistance gene tet(X6) and the carbapenemase gene blaIMP-45 were identified in the genome of the strain J68. The isolate belonged to sequence type ST15. For the first time, we report the emergence of tet(X6)- and blaIMP-45-positive P. asiatica strain isolated from a poultry source. The strain J68 exhibited resistance to last-line antibiotics, including tigecycline and carbapenems. The emergence of tigecycline resistance gene tet(X6), along with carbapenem resistance gene blaIMP-45 in strain of chicken origin is noteworthy. Our findings highlight the need for continued monitoring of resistance genes in agricultural environments.",

Total 81 rhizobacterial strains were isolated from plant rhizospheres collected on Jeju Island. Among them, three isolates DR1-6, DR2-3, and DRB1-1 exhibiting antibacterial activity on artificial media were selected for further evaluation. In inoculation bioassays, disease severity on apple leaves was significantly reduced following treatment with mixtures of E. pyrifoliae and the rhizobacterial strains. Notably, DRB1-1 and DR2-3 reduced disease severity to levels comparable to antibiotic treatment, while DR1-6 showed only moderate suppression despite strong in vitro antibacterial activity. Quantitative analysis using qPCR revealed significant reductions in E. pyrifoliae populations on treated leaves, consistent with disease suppression. Based on 16S rRNA gene sequence analysis and scanning electron microscopy, strains DR1-6, DR2-3, and DRB1-1 were identified as Pseudomonas fluorescens, Serratia nematodiphila, and Paenibacillus polymyxa, respectively. These results indicate that the selected rhizobacterial strains have potential as biocontrol agents for managing black shoot blight in crop plants, including apple.",
        "42421768": "ID: 42421768\nTitle: Compartment-Specific Variation in Bacterial Microbiome and Polyphyllin Profiles in Paris polyphylla.\nAbstract: Paris polyphylla (P. polyphylla) is a valuable traditional Chinese medicinal plant, yet the spatial distribution of its compartment-specific bacterial microbiomes and their correlative relationships with bioactive polyphyllins remain poorly characterized. Here, we combined 16S rRNA amplicon sequencing, metabolite analysis, and bioinformatics to investigate the distribution patterns of bacterial communities and polyphyllins across bulk soil (BS), rhizosphere soil (RS), root endospheres (REs), stem endospheres (SEs), and leaf endospheres (LEs) of P. polyphylla. A spot inoculation assay was further used to verify the interactions between the dominant genus Pseudomonas (strain Pseudomonas palleroniana P6) and key polyphyllin I and VII. The results showed that polyphyllin I and II were highly accumulated in aerial SEs and leaves, whereas polyphyllin VI, VII, and diosgenin were predominantly concentrated in REs. Bacterial diversity and richness showed a gradual decline from BS to LE, with ecological niche differentiation identified as the primary driver of bacterial community divergence across compartments, which was further modulated by polyphyllin content. Pseudomonas, the dominant genus in all compartments, displayed a decreasing relative abundance with ascending compartmental niches, and its abundance was significantly negatively correlated with polyphyllin I levels but positively correlated with polyphyllin VII levels-a trend experimentally validated by gradient polyphyllin concentration-based microbial growth assays. Redundancy analysis (RDA) indicated that polyphyllin content (especially VI, VII, and diosgenin) significantly influenced bacterial community composition. Additionally, P. polyphylla exhibited selective enrichment of beneficial microbes, with selection pressure intensifying progressively across compartments. This study clarifies the compartment-specific distribution patterns of bacterial microbiomes and polyphyllins in P. polyphylla and their correlative relationships, deepens the understanding of plant-microbiome interactions in medicinal plants, and provides a theoretical basis for optimizing P. polyphylla cultivation strategies and developing microbial inoculants for sustainable agricultural production.",
        "42422065": "ID: 42422065\nTitle: Machine learning-driven discovery of antimicrobial peptides against Pseudomonas aeruginosa.\nAbstract: Antibiotic resistance has become a global health crisis, driving the urgent need for novel antibacterial strategies. Antimicrobial peptides (AMPs) have emerged as promising therapeutic candidates due to their broad-spectrum activity and low propensity for resistance development. However, conventional discovery approaches remain time-consuming and inefficient for large-scale screening. In this study, we developed an integrated prediction framework that combines deep learning with classical machine learning methods to enable rapid and accurate identification of AMPs. The model was applied to screen over 250,000 artificially generated peptide sequences. Candidate peptides were selected based on physicochemical descriptors and activity-associated features, followed by solid-phase synthesis and minimum inhibitory concentration assays against Pseudomonas aeruginosa. Mechanistic investigations were conducted using scanning electron microscopy to visualize membrane damage, molecular dynamics simulations to probe peptide-membrane interactions, and transcriptomic profiling to assess bacterial stress responses and metabolic pathway alterations. Ten promising antibacterial candidates were successfully identified and experimentally validated. All selected peptides exhibited measurable activity against P. aeruginosa, with several showing potent inhibitory effects. Microscopic and simulation analyses confirmed that the peptides exert their antibacterial effects primarily through membrane disruption. Transcriptomic data further revealed that these peptides interfere with key metabolic pathways and activate bacterial stress response systems. Our findings demonstrate that the integrated deep learning-machine learning pipeline offers an efficient and reliable approach for large-scale AMP discovery. The mechanistic insights gained from this study not only validate the predicted candidates but also provide a foundation for rational optimization of peptide-based therapeutics. This comprehensive strategy holds promise for accelerating the development of next-generation alternatives to conventional antibiotics.",
        "42422472": "ID: 42422472\nTitle: stackPredAMR-a stacked random forest approach improves AMR phenotype prediction for multiple species and antimicrobial agents.\nAbstract: Antimicrobial resistance is a growing global threat, creating a need for rapid and accurate antimicrobial susceptibility testing. Current phenotypic antimicrobial susceptibility testing methods rely on prior isolation and cultivation, making them time-consuming. Whole genome sequencing combined with machine learning offers a faster and cost-effective alternative, but existing approaches are often limited in species coverage, antimicrobial scope, or data availability. We developed stackPredAMR, a machine learning framework for predicting resistance to 18 antimicrobial agents in three clinically important bacterial species: Escherichia coli, Klebsiella pneumoniae, and Acinetobacter baumannii. The model uses antimicrobial resistance gene presence as input and incorporates cross-resistance patterns through a stacked architecture with two random forest layers. Benchmarking on more than 2500 publicly available whole genome sequencing datasets with linked phenotypic resistance data showed strong performance, achieving a median accuracy of 0.94, ROC AUC of 0.97, and F1-score of 0.91, outperforming previously published methods. stackPredAMR is freely available and designed to support future extension to additional species and antimicrobial agents. Source code and datasets (database-driven reference approach, sample lists, and input features) are available at WIN-KID repository (https://github.com/IKIM-Essen/WIN-KID/tree/v1.0.0.0) and the release page (https://github.com/IKIM-Essen/WIN-KID/releases/tag/v1.0.0.0).",
        "42422733": "ID: 42422733\nTitle: Convergent GenX biodegradation by genomically designed and functionally screened synthetic bacterial consortia.\nAbstract: GenX (hexafluoropropylene oxide dimer acid) has been introduced as a replacement for legacy polyfluoroalkyl substances (PFASs) compounds; however, accumulating evidence indicates this C6 ether-PFAS may exhibit comparable toxicity to PFOA while persisting in contaminated water supplies. Biological remediation offers genuine mineralization potential but has been constrained by the exceptional stability of carbon-fluorine bonds. Here, we demonstrate that synthetic bacterial consortia assembled through rational genomic design (GENIA) or microfluidic selection (Community G) achieve rapid GenX biodegradation through metabolic complementarity among functionally specialized taxa. Both consortia removed >80% of GenX within 3 days (GENIA: 94.6%; Community G: 80.6%), with defluorination confirmed by fluoride release (82.6 and 69.6%, respectively). First-order kinetic modeling yielded rate constants of k = 0.87 day-1 (GENIA) and k = 0.64 day-1 (Community G), corresponding to half-lives under 1.1 days. Despite pronounced taxonomic divergence, GENIA maintained a stable composition, whereas Community G underwent dramatic restructuring, enriching for specialists of Salmonella, Pseudomonas, and Stenotrophomonas. Comparative genomic analysis revealed functional equivalence, with no significant differences in PFAS-degrading gene content (p = 0.844). Multi-guild community architecture emerged wherein primary degraders (40%-60% abundance) harboring haloacid dehalogenases performed initial C-F bond cleavage, detoxification specialists possessing glutathione S-transferases and fluoride exporters (>90% universal distribution) processed toxic intermediates, and metabolic support taxa enhanced resilience. Molecular docking simulations predicted favorable binding of GenX across phylogenetically diverse dehalogenases (\u0394G = -7.0 to -8.1 kcal/mol), suggesting thermodynamic compatibility with enzymatic catalysis. These results are predictive and computational; docking cannot confirm enzymatic activity or substrate turnover. Experimental validation (enzyme kinetics, purified protein assays) is required. Critically, GENIA activity did not disrupt indigenous soil microbiomes. The data support that GENIA does not cause detectable diversity loss, a necessary but not sufficient condition for ecological compatibility. These findings establish that functional gene diversity, distributed across metabolically complementary taxa through either rational design or adaptive selection, enables efficient PFAS bioremediation, converting recalcitrant \"forever chemicals\" into biodegradable substrates through engineered microbial complexity.",

This study evaluated the antimicrobial activity of bacteria isolated from sediments and endophytic tissues of Avicennia germinans from the Vichayal mangroves (Piura, northern Peru) using the volatile organic compounds test (VOCt), the Over Plate Test (OpT), minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) against Gram-positive pathogenic bacteria (Enterococcus faecalis, Staphylococcus epidermidis, S. aureus, and Listeria monocytogenes), Gram-negative pathogenic bacteria (Escherichia coli and Salmonella enterica sv. typhimurium), and two Candida species (Candida albicans and C. tropicalis), as well as their application in the preservation of Scomber japonicus fillets, prior to biosafety testing and phylogenetic analysis. A total of 34 isolates were obtained - 21 from sediments and 13 from A. germinans. Based on the VOCt and OpT assays, seven strains were identified by 16S rDNA sequencing as Bacillus albus ZB3, Priestia flexa (ZA5 and ZA9), Enterococcus faecalis ZB5, Pseudomonas monteilii (ZA1 and ZAAgR1), and Acinetobacter junii ZB7, yielding cell-free extracts containing bioactive substances (42.95-47.44 mg/mL). MIC results showed that 85.7% of the strains inhibited S. aureus ATCC25923 and E. coli O157:H7, while MBC activity was confirmed for ZA1, ZB3, and ZAAgR1 at extract concentrations \u226510%. The biosafety profile revealed gamma-hemolysis and the absence of DNase activity across all strains, consistent with a non-virulent phenotype; however, widespread antibiotic resistance was detected. Application of cell-free extracts to mackerel fillets demonstrated that B. albus ZB3 reduced aerobic mesophile counts (6.19 vs. 6.46 log\u2081\u2080 CFU/g) at ambient temperature (27 \u00b1 2 \u00b0C, 2 days), while P. monteilii ZAAgR1 was more effective under refrigeration (6.19 vs. 6.36 log\u2081\u2080 CFU/g, 7 \u00b1 2 \u00b0C, 7 days). These findings identify bacteria associated with the Vichayal mangroves as promising candidates for fishery product preservation, pending comprehensive genomic and safety characterization.",
        "42422745": "ID: 42422745\nTitle: Diverse banana endophytes reveal potential genotype-driven community structure affected by domestication.\nAbstract: Plant endophytic microbiomes play critical roles in plant health, productivity, and stress tolerance, however, their relationship with host genotype remains poorly understood. This study focused on endophytic microbiomes of six banana (Musa spp.) cultivars grown under shared environmental conditions to determine how genotype influences microbial diversity and structure. We used deep amplicon sequencing to investigate the endophytic microbiomes from above- and below-ground tissues of wild diploid cultivars Musa balbisiana, M. balbisiana \"Thai Black\", and M. textilis, and domesticated triploid cultivars Dwarf Cavendish, Williams Hybrid, and hybrid FHIA-25, grown in sympatry. Across all samples, dominant genera included Pseudomonas, Acinetobacter, Enterobacter, Devosia, and Rhizobium, while 27.4% of ASVs were unclassified. Although many core taxa were shared, each cultivar and tissue harbored distinct low-abundance microbial taxa. Beta diversity analyses revealed that banana cultivar explained a small but significant proportion of community variation (Bray-Curtis R 2\u202f=\u202f2.7%, p\u202f=\u202f0.002; Weighted UniFrac R 2\u202f=\u202f2.9%, p\u202f=\u202f0.005), whereas tissue type and domestication contributed less to overall variation. PICRUSt2 predicted functional differences among endophytic communities across banana cultivars, with 49 pathways differing between wild and domesticated plants, including enrichment of lipid metabolism, biotin biosynthesis, and aromatic compound degradation in domesticated cultivars. However, because domestication status and ploidy differed among the selected cultivars, these effects could not be fully separated in the current study. Together, these results indicate that banana genotype influences endophytic microbiome composition and predicted function, although host genotype accounted for only a modest proportion of the observed variation, highlighting the importance of additional ecological and environmental factors in shaping plant-associated microbial communities.",
        "42422903": "ID: 42422903\nTitle: Spectroscopic discrimination of bacterial species of variable pathogenicity through explainable machine learning.\nAbstract: Rapid and accurate identification of bacterial pathogens and their degree of pathogenicity is essential for guiding antimicrobial therapy. Current culture-based methods require a timeframe of at least 24-48 h for species-level identification alone, which often leads to substantial disease progression and increases the propensity of antimicrobial resistance (AMR). Surface-Enhanced Raman Spectroscopy (SERS) shows promise in mitigating these drawbacks by providing a fast, non-invasive, label-free method to capture the biochemical fingerprints of bacteria achievable under clinical settings. However, the molecular complexity of SERS spectra, which has been an impediment for conventional data analysis, demands robust computational frameworks for reliable species-level identification. Here, we employ a comprehensive SERS analysis scheme with supervised machine learning and explainable artificial intelligence (XAI) to discriminate five clinically relevant pathogens, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), and Enterococcus faecalis, and to probe their degree of pathogenicity from a biomarker perspective. Among the tested models - Support Vector Machine (SVM), k-Nearest Neighbour (kNN), Random Forest (RF), and a 1D Convolutional Neural Network (CNN) - CNN achieved near-perfect classification accuracy, capturing subtle and spectrally relevant variations often inaccessible to traditional algorithms. Notably, the 1D-CNN also achieved 100% discrimination between MRSA and methicillin-sensitive S. aureus - two strains of the same species differing only in resistance phenotype. To ensure transparent decision-making and eliminate the black-box nature of machine learning models, SHapley Additive exPlanations (SHAP) analysis was applied to both RF and CNN models, which facilitated the convergence of both frameworks on the same discriminatory Raman regions, revealing conserved biochemical determinants of species identity. Complementary MCR-ALS decomposition further resolved the spectra into interpretable biochemical components and provided the rubric for biochemical differentiation. Together, this study aims to demonstrate an end-to-end explainable workflow that couples SERS with interpretable AI, offering a rapid, transparent approach for pathogenic disease diagnosis."
