  33. Over the last 30 years, two population-scale health crises have emerged as the epidemic of diet-related cardiometabolic disease (obesity, type 2 diabetes, hypertension, and cardiovascular disease) and the spread of antimicrobial resistance (AMR) as a major cause of death globally. Typically, they are investigated and controlled independently of each other. AMR may be amplified by diet-induced cardiometabolic dysfunction, which is not a parallel but an upstream, under-recognized burden. We...
  34. Microbial metabolites can suppress or promote tumor development and modify treatment response, but the direction of an effect depends on its chemical identity, anatomical source, concentration and host target. This narrative review critically examines short-chain fatty acids, tryptophan derivatives, secondary bile acids, colibactin, cyclic dinucleotides and microbial activities that alter anticancer drugs. We distinguish individual metabolites from postbiotic preparations, microbial components...
  35. Antimicrobial resistance (AMR) is increasing rapidly, necessitating the development of non-traditional therapeutic approaches.

Aquatic environments may serve as reservoirs and dissemination pathways for colistin resistance; however, the available evidence remains fragmented. This systematic review aimed to synthesize...
  61. Adaptation to abiotic stress is typically studied in single-species cultures, yet bacteria inhabit and evolve in multispecies communities where neighboring organisms reshape, for example, nutrient availability, redox state, and cellular physiology. We recently demonstrated that interspecies interactions can alter the fitness effects of antibiotic resistance mutations, and we suggest that this reflects a broader principle. Stress-response networks are extensively cross-regulated and draw upon a...
  62. Antimicrobial resistance (AMR) poses an escalating global threat, yet surveillance and mechanistic understanding remain anchored in individual resistance genes, an approach that is inadequate for capturing the ecological, genomic, and metabolic complexity through which resistance emerges and spreads. In this opinion article, we argue that genome-scale metabolic models (GEMs) offer a principled framework for advancing AMR research beyond this gene-centric paradigm. Strain-resolved GEMs embed...
  63. Antibiotic growth promoters are increasingly restricted in broiler production over concerns about antimicrobial resistance, prompting interest in phytotherapies such as chicory. However, individual trials on dietary chicory in broilers report inconsistent effects on growth performance, limiting confident commercial translation. This study synthesized data from 2010 to 2025 to estimate the pooled effect of chicory on feed intake (FI), body weight gain (BWG), and feed conversion ratio (FCR) in...

This review systematically evaluates the limitations of SPE in seawater matrices and examines two emerging...
  65. The 2026 WHO guidelines recommending doxycycline post-exposure prophylaxis (doxy-PEP) represent the first global antibiotic prophylaxis recommendation for bacterial sexually transmitted infections (STIs), with provisions for antimicrobial resistance (AMR) monitoring.Doxy-PEP should be governed as an adaptive intervention subject to periodic, transparent review, but establishing decision rules faces challenges.Doxy-PEP is expected to select for resistance, including in Neisseria gonorrhoeae,...
  66. The escalating crisis of antibiotic resistance has driven the global livestock and poultry industry to seek effective alternatives. Bacteriophages (phages) are promising candidates because their high host specificity allows targeted elimination of key intestinal pathogens, including Salmonella, Campylobacter, pathogenic Escherichia coli, and Clostridium perfringens, while sparing commensal microbiota. This review summarizes the mechanisms by which phages promote intestinal health in livestock...
  67. Environmental transmission of antibiotic resistance poses a risk to human health. Understanding the behavior and health risks of antibiotic resistance genes (ARGs) in the environment requires accurate nucleic acid analyses. Technical challenges remain in the sequencing of ARGs in low abundance relative to total environmental DNA and in on-site analysis. CRISPR technology has been applied to the characterization and monitoring of ARGs in various environmental media. For sequencing of ARGs, CRISPR...
  68. CONCLUSIONS: Standard urine culture may be insufficient for managing recurrent or atypical UTIs. We advocate for a personalized diagnostic and therapeutic approach that integrates molecular insights, aiming to curb antibiotic overuse and improve patient outcomes in the era of rising drug resistance.
  69. Microplastics and nanoplastics (MPs/NPs) are increasingly recognized as biologically active interfaces that may reshape host-microbe interactions in carcinogenesis. This review proposes a hypothesis-generating mechanistic framework in which MPs/NPs may influence cancer-related processes through the integration of environmental exposure, epithelial barrier disruption, immune dysregulation, and tumor microenvironment remodeling. Although applicable to multiple epithelial interfaces, the framework...

Whole-genome sequencing (WGS), with its high resolution and throughput, provides comprehensive genetic information from pathogens, opening new...
  71. CONCLUSION: The Y93H substitution is a frequent naturally occurring variant in untreated HCV genotype 1b infection. Despite reduced clinical relevance with pangenotypic DAAs, its persistence warrants continued monitoring. Standardized sequencing and global resistance surveillance remain essential for optimizing treatment strategies and informing antiviral policy.
  72. CONCLUSION: Bacteriophage therapy represents a biologically rational and logistically feasible intervention for health systems under siege. While large-scale randomised controlled trial evidence remains limited, pragmatic deployment supported by compassionate use data and adaptive regulatory frameworks provides justification for clinical application against otherwise untreatable infections in conflict and resource-limited settings. Targeted investments in phage biobanking, rapid point-of-care...
  73. Intratumoral microbiota, as an important component of the tumor microenvironment, have attracted increasing attention in recent years for their roles in tumor initiation, progression, and therapeutic regulation. Accumulating evidence indicates that low-abundance yet relatively stable microbial communities are present in a variety of solid tumors, exhibiting marked tumor-type specificity and spatial heterogeneity. Current studies suggest that intratumoral microorganisms contribute to tumor...
  74. Pseudomonas aeruginosa is the leading cause of chronic respiratory infection in people with cystic fibrosis (pwCF) and remains a major driver of morbidity and premature mortality. The unique environment of the CF lung promotes persistent colonisation, biofilm formation, and the emergence of multidrug-resistant (MDR) phenotypes, severely limiting the effectiveness of conventional antibiotic therapies. Despite aggressive and prolonged antibiotic regimens, eradication of chronic P. aeruginosa...
  75. Cytotoxic chemotherapy remains an important component of multimodal treatment for many solid tumors, but resistance and dose-limiting toxicities continue to constrain clinical benefit. The gut microbiome can influence chemotherapy response through microbial drug biotransformation, metabolite signaling, intestinal-barrier integrity, systemic immune regulation, and tumor-cell stress and death pathways. Across solid tumors, the evidence is strongest in colorectal cancer, where clinical associations...

Antibiotic resistance has become a major global health concern with marked regional variations, severely undermining empirical treatment efficacy. Resistance mechanisms primarily involve target gene mutations, efflux pump overexpression, and altered membrane permeability. This review summarizes resistance mechanisms of commonly used...
  77. Antimicrobial resistance (AMR) is a major global health threat, with the greatest burden falling on low- and middle-income countries (LMICs) also challenged with limited surveillance capacity. The UK Government's Fleming Fund was established in 2015 to strengthen AMR surveillance across Africa and Asia through a One Health approach. This paper draws on program experience, country implementation evidence, and published literature to describe how the Fleming Fund operationalized AMR surveillance,...
  78. CONCLUSIONS: Fleming Fund experience suggests that surveillance is more likely to inform action when data use is built into system design. Continued investment will be needed if AMR surveillance is to improve policy and practice in low- and middle-income countries.
  79. Antimicrobial resistance and unnecessary antibiotic exposure remain significant problems in clinical practice. Procalcitonin (PCT) has emerged as a clinically relevant biomarker to assist in antibiotic decision-making in patients with suspected bacterial infections. PCT levels may increase in response to bacterial infection and changes in disease activity; however, its diagnostic performance and clinical value are context-dependent, and interpretation of its results requires careful...
  80. CONCLUSION: Preserving azithromycin requires coordinated health-system interventions that integrate accessible diagnostics, pathogen-directed antimicrobial stewardship, resistance surveillance, regulation of antibiotic access, and vaccination. Such an approach is particularly important in LMICs, where azithromycin remains one of the few accessible oral options for severe enteric infections.
  81. Urinary tract infections (UTIs) remain among the most common bacterial infections worldwide, affecting millions every year. While Escherichia coli (E. coli) is the predominant pathogen, a broad range of Gram-negative and Gram-positive organisms can be implicated. Treating UTIs, particularly complicated or severe infections, frequently relies on broad-spectrum antibiotics, often started empirically before identifying the causative pathogen. However, despite their ability to cover a wide spectrum...
  82.

  90. The intratumoral microbiome critically influences immunotherapy efficacy by modulating the host immune microenvironment and epigenetic landscape through its metabolites. Microbial derived metabolites such as short chain fatty acids, secondary bile acids, trimethylamine N oxide, and tryptophan derivatives reprogram host cell epigenetics via DNA methylation, histone modifications, and non-coding RNAs, thereby shaping anti-tumor immunity and driving either immune activation or resistance. In turn,...
  91. Extracellular vesicles have been observed to bud from eukaryotic cells and bacteria. These membranebound, spherical structures range from 20 to 500 nm in diameter and enclose diverse molecular components. In eukaryotic cells, exosomes represent the prototypical extracellular vesicles. Gram-negative bacteria release outer membrane vesicles, whereas Gram-positive bacteria produce membrane vesicles despite their thick peptidoglycan-rich cell wall. More recently, outer-inner membrane vesicles have...
  92. Tuberculosis (TB) treatment is increasingly challenged by both antimicrobial resistance (AMR) and phenotypic drug tolerance, the latter representing a reversible physiological state that contributes to persistence and prolonged therapy. While AMR is driven by heritable genetic mutations, drug tolerance arises from reversible physiological adaptations that enable bacterial survival during prolonged antibiotic exposure. Increasing evidence suggests that metabolic remodeling plays a central role in...
  93. The occurrence of antimicrobial resistance (AMR) and chemoresistance (CMR) during bacterial infections and cancer progression, respectively, has become a serious threat leading to increased mortality rates and putting significant pressure on healthcare systems globally. The design and application of new bioanalytical methodologies capable of early AMR and CMR detection in patients is urgently needed to overcome the challenges imposed by drug resistance. Electrochemical methods and (bio)sensors...
  94. Growing herbicide resistance and concerns regarding the environmental and health impacts of synthetic herbicides have intensified interest in plant-derived weed-management products. This review assesses the phytotoxic, herbicidal, and allelopathic potential of essential oils, emphasizing efficacy, selectivity, formulation, and delivery. Relevant literature was identified through searches of Scopus, Web of Science, and Google Scholar, using terms related to essential oils, phytotoxicity,...
  95. Antimicrobial resistance (AMR) has intensified the need for antibacterial agents with alternative chemical scaffolds and mechanisms of action. Plant-derived antibacterial compounds represent a chemically diverse source of bioactive molecules, but their therapeutic potential depends not only on in vitro potency but also on mechanistic validation, pharmacokinetic exposure, pharmacodynamic relationships, and biological safety. This review critically examines evidence published from 2014 to 2026 on...
  96. Antibiotics and antibiotic resistance genes (ARGs) are widespread in aquatic ecosystems affected by climate variability, urbanization, and intensifying aquaculture. Yet parent-antibiotic concentrations and resistance-related genetic endpoints do not always vary in parallel across seasons, sites, or environmental compartments. This discrepancy matters for aquatic animals as ecological receptors, potential vectors, and targets for antimicrobial resistance monitoring and management. To examine...
  97. Infective endocarditis (IE) is a rare but life-threatening infection of the endocardial surface of the heart, usually arising when circulating microorganisms colonise the cardiac valves; it carries an in-hospital mortality of roughly 15-30%. Because oral viridans group streptococci cause a substantial proportion of community-acquired cases, antibiotic prophylaxis (AP) before invasive dental procedures has historically been central to prevention, placing dental practitioners at the centre of a...
  98. Background/Objectives: Biofilm formation on invasive medical devices represents a major challenge in intensive care units (ICUs), contributing to device-associated infections, antimicrobial resistance, and adverse clinical outcomes. Despite its clinical relevance, the extent and characteristics of the available evidence on biofilm formation in invasive medical devices used in adult ICUs remain heterogeneous and incompletely mapped. The objective was to map and characterize the available evidence...
  99. Fungal endophytes act as bio-nano factories and are favored over bacteria and plant extracts, as they secrete large quantities of proteins and enzymes, facilitating stable, efficient, and economic nanoparticle synthesis. This review highlights the advantages of plant-associated fungal endophytes as bio-factories for metal nanoparticles (MNPs) synthesis and critically examines the biological activities and potential applications of these MNPs in human health, food technology, and agriculture....
  100. Pseudomonas aeruginosa is an opportunistic pathogen with high intrinsic and acquired antibiotic resistant levels, so the World Health Organization has defined this bacterium as a priority pathogen for research. In the case of Mexico, different strains belonging to a sequence-type (ST309) that is considered as high-risk due to its wide geographical distribution in different countries, and its high levels of antimicrobial resistance have been isolated, so the research with this bacterium is an...
