      The global rise of antimicrobial resistance (AMR) presents a critical threat to public health, with multidrug-resistant (MDR) bacterial infections rendering conventional antibiotic therapies increasingly ineffective. In this context, bacteriophage-based live biotherapeutics have emerged as a promising alternative or adjunct to traditional antibiotics. Bacteriophages, viruses that selectively infect and lyse bacteria, offer a unique therapeutic potential due to their specificity, self-amplification at the site of infection, and ability to disrupt biofilms. These phages offer a range of strategies to combat resistant infections, from traditional phage therapy to advanced approaches such as genetically engineered phages, phage-derived enzymes, and phage-antibiotic combinations. Understanding the mechanisms by which bacteriophages identify and destroy their bacterial hosts not only enhances our knowledge of their therapeutic potential but also supports the development of more effective treatments. Their high specificity allows targeted bacterial clearance with minimal impact on the normal microbiota. In addition, phages can adapt to bacterial mutations, making them a dynamic tool in the fight against resistance. Evidence from clinical trials further reinforces their efficacy in real-world healthcare settings, validating their role as viable biotherapeutics. Together, these advantages position bacteriophages as a powerful and adaptable tool in the global fight against AMR.

      Urinary tract infections (UTIs) caused by uropathogenic Escherichia coli (UPEC) are one of the most common bacterial infections in humans. The rise of multidrug-resistant UPEC strains increases the urgent need for alternative treatment. Two diverse lytic bacteriophages (phages), SR02 and SR04, recently exhibited an in vitro anti-UPEC activity. In this study, we reported the interplay among UPEC, phages, and the microenvironment of mammalian urinary tract in UTI phage therapy using both in vitro (human bladder cell line) and in vivo (murine acute UTI) models. A gentamicin protection invasion assay was performed in UPEC-infected human bladder cells (UM-UC-3). Both monophages and the phage cocktail significantly reduced UPEC invasion into UM-UC-3 with a synergistic effect between SR02 and SR04. Female C57BL/6 mice were transurethrally infected with 107 colony-forming units of UPEC, and 2 h later, 108 plaque-forming units of monophages and cocktail were single transurethrally administered to the mouse bladder. At 24 h post-UPEC infection, the cocktail significantly reduced UPEC colonization in the mouse bladder and kidney, but not in the urine. The synergism between SR02 and SR04 was observed only in the mouse bladder. Both monophages and cocktail markedly reduced UPEC ascension into mouse kidneys without a synergism or robust tissue proinflammatory cytokine gene expression. However, increased polymorphonuclear cell infiltration was observed in the bladders of SR04-treated mice. In conclusion, we report the contribution of different host urinary tract microenvironments (urine, bladder, and kidney) in the outcomes of UTI phage therapy with two lytic phages and their combination.

      Pulmonary infections pose a significant global health challenge to human life and health. In patients with chronic pulmonary diseases such as cystic fibrosis and bronchiectasis, structural abnormalities of the airways and impaired mucociliary clearance contribute to recurrent and challenging pulmonary infections. These infections are frequently complicated by antimicrobial resistance, making them difficult to treat with conventional antibiotics. As a result, phage therapy has emerged as a promising alternative for treating resistant pulmonary infections. Recently, the integration of artificial intelligence (AI) has improved the efficiency of phage selection. Nevertheless, the accuracy of predicting phage-bacterial host interactions remains limited, posing a significant obstacle to the clinical translation of phage-based therapies. To address this issue, we propose a deep Siamese network framework for precision phage selection in pulmonary infections. Specifically, we employ an identical model architecture to process both phage and host genomes. Initially, the genomic sequences of both phages and hosts are encoded into feature representations using k-mer segmentation followed by the skip-gram model. Subsequently, convolutional neural networks (CNNs) and Transformers are introduced to extract local and global features, respectively. Finally, the extracted features are fused to predict phage-host interactions. Experimental results on dataset created from the NCBI genome database demonstrate that our proposed method achieves superior performance in the precise identification of phages targeting specific bacterial hosts, thereby supporting its potential application in phage therapy for pulmonary infections.

      With the increase in the placement of prosthetic joints and other hardware in the body, associated infections have risen. These infections are complicated to treat due to the underlying bacteria generating matrices that resist clearance by immune system effectors or antibiotics. These matrices, biofilms, have two primary ways of being eradicated: either by physical removal during surgery or by killing the underlying bacteria, usually with antibiotics. The viruses that kill bacteria, bacteriophages, are readily capable of entering biofilms and eradicating the bacteria therein. Therefore, bacteriophages have therapeutic potential as a supplement to antibiotics for the treatment of prosthetic joint infections. In this investigation, we generate a mathematical and computer-simulation model to explore the contributions of the innate immune system with antibiotics, bacteriophage, and the joint action to control biofilm-associated infections. Our results question the proposition that bacteriophages are an effective addition in the treatment of prosthetic joint infections.

       BACKGROUND: Klebsiella pneumoniae, a prominent member of the ESKAPE pathogen group (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species), represents a serious concern in postoperative gynaecological infections due to its multidrug resistance (MDR) and strong biofilm-forming ability. The limited efficacy of conventional antibiotics against such infections underscores the need for innovative combinatorial strategies, such as bacteriophage therapy and phototherapy.
    AIMS: This study aimed to evaluate the synergistic antibacterial potential of bacteriophage therapy and blue light (450 nm) phototherapy against biofilm-associated MDR K. pneumoniae isolated from a post- cesarean wound infection.
    METHODS: A clinically isolated MDR K. pneumoniae strain was characterised, and biofilms were treated with phage, blue light, or sequential phage-light combinations. Crystal violet assays and microscopy quantified biofilm biomass reduction, while synergy was analysed using the Bliss independence model. Phage stability under blue light and cytocompatibility with HiFi™ human PBMCs were also assessed, along with cytokine profiling.
    RESULTS: The combined phage-blue light treatment achieved an 82.3% reduction in biofilm biomass, significantly surpassing either monotherapy (p < 0.0001). Sequence-dependent synergy was observed, with Phage→Light treatments showing stronger early effects (6 h). Phage viability remained unaffected by blue light, and PBMC assays confirmed high cytocompatibility with no detectable cytokine induction. Mechanistically, blue light-induced ROS disrupted the biofilm matrix, facilitating enhanced phage penetration and infection.
    CONCLUSIONS: Bacteriophage-blue light combination therapy represents a safe, synergistic, and resistance-mitigating approach for managing MDR K. pneumoniae biofilm infections, offering promising translational potential in postoperative gynaecological wound care.

      Pseudomonas aeruginosa is an opportunistic pathogen responsible for chronic infections in both human and veterinary medicine, with biofilm formation and multidrug resistance posing major clinical challenges. The efficacy of two bacteriophages, JG003 and PTLAW1, alone and in combination, was evaluated. In vitro biofilms grown on abiotic 96-well plates showed significant reduction after treatment with individual bacteriophages or their combination, as confirmed by confocal microscopy. To better simulate physiological conditions, efficacy was assessed using an epidermal equivalent model and an ex vivo canine skin model. In the ex vivo system, bacteriophage treatment reduced bacterial load by 4 logs, as confirmed by scanning electron microscopy and immunofluorescence imaging. In the epidermal equivalent model, bacteriophage therapy decreased bacterial counts and CXCL8 levels without inducing cytotoxicity or disrupting the skin barrier. Integration of in vitro and ex vivo systems bridges the gap between traditional biofilm assays and in vivo studies. The use of Franz-type diffusion cells provides a physiologically relevant platform for evaluating topical bacteriophage delivery and skin permeation. These findings establish a reproducible preclinical framework for biofilm-targeted therapies, demonstrating that bacteriophage combinations effectively reduce Pseudomonas aeruginosa biofilms and inflammation on skin, supporting their potential for wound treatment in both human and veterinary medicine.

      Shigella is a genus of bacteria that is a prevalent cause of bacterial diarrhoea (i.e., shigellosis). Shigella bacteriophages are shaping bacterial fitness. Bacteriophages can carry genes that contribute to Shigella virulence and antibiotic resistance, and these genes are frequently found on mobile genetic elements (MGEs). Horizontal gene transfer (HGT) of these components is a major driver of bacterial evolution. A comprehensive genomic analysis of these bacteriophages is required to deepen understanding of candidate genes for MGEs and HGTs. Through genetic exchange, phages acquire novel genetic features that confer selective advantages. In this study, we identified the weighted gene repertoire relatedness (wGRR) metric. We associated it with the infecting host species andgenetic exchanges among Shigella phages using the weighted gene repertoire relatedness (wGRR) metric. We associated them with the infecting host species and phage lifestyles to examine evolutionary constraints among phages. We observed that HGTs can affect genes' GC content, which, in turn, influences amino acid usage, thereby shaping the amino acid usage of the resulting proteins. Host-range expansion is also observed among Shigella phages. However, we also noted that Shigella phages do not have the propensity for genetic transfer with dissimilar lifestyles. The gene pool of bacteriophages, due to horizontal transfer, can broaden their host range, making them more suitable for applications in phage therapy against antibiotic-resistant bacteria. Horizontal gene transfer can expand the bacteriophage gene pool, thereby increasing host range and making them more suitable for phage therapy against antibiotic-resistant bacteria. Overall, this study provides deeper insight into MGEs and HGTs among Shigella phages and their evolutionary significance for infectivity.

      Acute pancreatitis (AP) is a common clinical inflammatory condition whose severity is closely associated with both local pancreatic injury and systemic complications. Research indicates that gut microbiota dysbiosis and subsequent bacterial translocation can exacerbate disease progression via the gut-pancreas axis, representing a critical factor influencing patient outcomes. Although antibiotics remain a primary approach for infection control, their extensive use has led to increasingly prominent issues of bacterial resistance, and their broad-spectrum nature may further disrupt microbial homeostasis. Within this context, phage therapy, by virtue of its high specificity for targeted bacterial elimination, offers a novel approach for precisely modulating the gut microbiota, demonstrating unique therapeutic potential. This review explores the emerging role of phage therapy in regulating the pancreas-gut axis, focusing on mechanisms such as precise pathogen eradication, immunomodulatory effects, and restoration of microbial equilibrium, thus effectively inhibiting the progression of pancreatitis. Finally, we discuss the challenges and future prospects of translating this promising strategy into clinical practice for AP.

      Antimicrobial resistance is a growing global healthcare crisis, driven by the rapid spread of resistant pathogens that compromise existing treatments. Carbapenem-resistant Klebsiella pneumoniae is a major public health threat, requiring novel therapeutic strategies. Phage therapy, which employs phages to target bacterial pathogens, is a promising approach, particularly when combined with antibiotics to enhance efficacy through synergistic interactions. In this study, time-kill curve assays were used to evaluate the synergy between the lytic phage vB_Kpn_2-P4 and meropenem against twelve K. pneumoniae clinical isolates from Spanish hospitals that carried diverse carbapenemases. Notably, in OXA-48-producing isolates, this combination prevented the emergence of resistant mutants, highlighting the therapeutic potential of phage-antibiotic synergy. The observed effect, linked to the presence of the pOXA-48 plasmid, suggests a promising strategy for combating multidrug-resistant bacteria.

      The STAR-IDAZ international research consortium established a working group on Alternatives to Antimicrobials to explore various approaches for reducing our reliance on antimicrobials. These included bacteriophages, activating the immune system and manipulating the microbiome. The sub-group investigating bacteriophages have developed a road map for the application of phages in a One Health context. We present this roadmap here, in review format, along with a discussion of how phages may be combined with other therapies.

      There is an urgent need for alternative solutions to combat multidrug-resistant (MDR) E. coli infections. In recent years, there has been an increase in MDR strains causing urinary tract infections (UTIs), which has resulted in more challenging treatment options, increased healthcare costs and prolonged hospital stays. The utilization of bacteriophages as a prospective modality for the management of bacterial infections has garnered significant attention. The objective of this study was to isolate and describe a phage capable of infecting MDR E. coli strains isolated from the urine of patients affected with UTI. The phage EcoPhCCP1 was isolated using the plaque assay from the influent of a wastewater treatment plant. The phage was characterized by phenotypic and genomic features. Morphological characteristics such as shape and size were determined using electron microscopy, and its host range was determined against multiple MDR strains. The complete genome of the phage was subjected to whole-genome sequencing and then assembled and annotated to search for virulence or antimicrobial resistance gene (ARG). VIRIDIC was employed to compare the closest phage genomes, while VICTOR and taxMyPhage were used to construct its phylogeny. EcoPhCCP1 is a tailed phage capable of infecting and propagating in multiple MDR E. coli strains recovered from UTI. The phage genome is 44,482 bp in length, with a GC content of 50.7 mol%, and encodes 87 ORFs, 33 of which have been previously functionally annotated. Phage EcoPhCCP1 is a Kagunavirus, in the recently created Sarkviridae family. Notably, phage EcoPhCCP1 does not harbour ARGs or virulence genes, thus rendering it a promising candidate for phage therapy against clinically significant MDR E. coli strains. Moreover, phage EcoPhCCP1 possesses putative anti-CRISPR proteins.

       OBJECTIVE: Phage therapy is emerging as alternative therapy for difficult-to-treat bacterial infections. Flow cytometry (FCM) can screen for infective phages rapidly, reducing time taken for screening infective phages to deliver a timely and effective phage-based therapy. Phage infection increases reactive oxygen species in bacteria, which cause oxidative damage, such as protein carbonylation - an irreversible addition of carbonyls to amino acids, causing loss-of-function in proteins. We aim to assess carbonylation for predicting bacterial response to phage infection. We hypothesise that the extent of protein carbonylation corresponds to the susceptibility of bacteria to phage.
    METHOD: Fourteen Pseudomonas aeruginosa clinical isolates were exposed to bacteriophage at a bacteriophage:bacteria ratio of 100:1. Bacteria were then stained with cascade-blue hydrazine, which labels carbonylation, prior to FCM. Fluorescence intensities of cascade-blue hydrazine from FCM analyses were used to construct polar plots, illustrating both the extent of carbonylation and heterogeneity of isolates exhibiting carbonylation.
    RESULT: Increased carbonylation was observed at 2 hours-post-phage-infection (hppi), in clinical isolates determined to be phage-susceptible by double agar overlay assay. FCM further revealed decreased carbonylation in several isolates at 4-hppi from 2-hppi. Phasor approach was adopted to estimate when the isolate would exhibit decreased carbonylation. Our estimations are hitherto accurate in 11 of 14 isolates assessed (accuracy: 78.6%).
    CONCLUSION: Compared to traditional methods requiring overnight incubation, assessing carbonylation by FCM is more rapid at determining phage infectivity. As carbonylation often cause irreversible loss-of-functions in proteins, we postulate the onset of subsequent, decreased carbonylation indicates bacterial attempt to survive by degrading carbonylated proteins.

      Phage and antibiotic synergy (PAS) are often adopted clinically to address shortcomings of phage monotherapy. While treatment order has shown to significantly influence the extent of synergy, the underlying mechanisms remain poorly understood, particularly in the context of planktonic bacterial populations. Building on a previously identified PAS combination, IME-AB2 phage and colistin, demonstrating sequential effects, we conducted a systematic investigation to elucidate mechanisms driving the phenotypic outcomes of three treatment orders (phage-first, simultaneous and antibiotic-first) against a resistant Acinetobacter baumannii. Our findings revealed phage pretreatment effectively decapsulated bacteria to promote colistin binding and bacterial killing, while colistin pretreatment altered bacterial morphology and intracellular machinery, reducing phage reproduction and hence the PAS level. For simultaneous treatment, colistin also reduced the phage reproduction rate, but phage-mediated bacterial decapsulation promoted colistin binding and outer membrane disruption, leading to significant PAS. Noteworthy, only the simultaneous treatment capable of suppressing resistance evolvement. Genome sequencing analysis revealed that colistin-pretreated bacteria modified LPS/outer membrane structure via regulating the QseB/C signal transduction system to promote resistance. On the other hand, phage-pretreated bacteria acquired mutation in gene clusters related to polysaccharide synthesis, impairing phage adsorption at the cost of weakening biofilm formation ability. Overall, this extended mechanistic study provided important insights into the impacts of treatment orders on PAS and resistance dynamics, suggesting the need for more fundamental studies to realize the full clinical potential of the PAS strategy.

      Biofilms are intricately organized microbial communities enveloped in self-produced extracellular polymeric substances. They display remarkable resilience to environmental and antimicrobial stresses and adhere to various surfaces. Synthetic biology, which combines molecular biology with engineering principles, offers tools to modulate biofilm behaviour for biotechnological applications and to address associated challenges. This review examines recent developments at the intersection of biofilm engineering and synthetic biology, highlighting strategies such as phage therapy, electrogenetic systems, microbial consortia design, quorum sensing regulation, genetic circuits, extracellular polymeric substances modification, and antimicrobial peptide-coated surfaces. These tools allow precise manipulation of biofilm structure, composition, and metabolic output. Biofilms are increasingly optimized for applications such as wastewater treatment, bioremediation, bioenergy, and diagnostics. Enhancements in stability and function are achieved via engineered circuits and extracellular polymeric substances adjustments, while antimicrobial approaches help control pathogenic biofilms. Despite these innovations, challenges remain, including biosafety, heterogeneity, scalability, and regulatory compliance. Continued interdisciplinary efforts are essential for translating these systems into viable technologies.

      Cardiovascular diseases (CVDs) remain the leading cause of global mortality, with standard pharmacological interventions often failing to fully address their complex pathophysiology. Recent advances in microbial medicine highlight the human gut microbiome as a critical regulator of cardiovascular health. Gut microbial metabolites such as short-chain fatty acids (SCFAs), trimethylamine-N-oxide (TMAO), and indole derivatives play pivotal roles in modulating inflammation, lipid metabolism, immune function, and vascular homeostasis. Dysbiosis, or microbial imbalance, has been strongly associated with atherosclerosis, hypertension, and heart failure. Consequently, therapies targeting the gut microbiota including probiotics, prebiotics, synbiotics, and postbiotics have emerged as promising adjuncts in CVD prevention and treatment. Moreover, fecal microbiota transplantation (FMT) and synthetic biology approaches using engineered microbes offer novel strategies to restore microbial balance and deliver therapeutic molecules. Dietary interventions, particularly Mediterranean and fiber-rich diets, further support cardiovascular health through microbiota modulation. While preclinical and clinical studies underscore the potential of microbiome-based interventions, challenges related to strain specificity, delivery systems, and regulatory frameworks remain. Nonetheless, integrating microbial medicine into cardiovascular care represents a transformative shift toward precision, holistic, and personalized treatment paradigms. This chapter explores these cutting-edge therapeutic interventions and their implications for reshaping the future landscape of cardiovascular disease management.

      Antimicrobial resistance (AMR) represents one of the most critical global health challenges of the twenty-first century. The emergence and spread of microorganisms that no longer respond to the available antibiotics has prompted the World Health Organization to call for renewed commitment and investments in the discovery and development of novel prophylactic and therapeutic strategies. In particular, vaccines can help reduce the incidence caused by antimicrobial-resistant pathogens, thereby decreasing the need for antibiotics and the risk of selecting resistant strains. Here we describe standard and innovative approaches to vaccine design starting from live-attenuated and killed whole-cell vaccines, going through the revolution represented by Reverse Vaccinology and recombinant DNA technologies, and finally ending with rational vaccine design allowed by monoclonal antibody discovery, structural biology, nanoparticles and mRNA biology. Overall, we expect that the recent major progress in vaccinology will enhance health protection and reduce the impact of the AMR phenomenon in high-income as well as in low- and middle-income countries. This article is part of the Royal Society Science+ meeting issue 'Vaccines and antimicrobial resistance: from science to policy'.

      The development of resistance to antibiotics and bacteriophages highlights the necessity of alternative therapy for Staphylococcus aureus. This study aimed to explore the utility of temperate phages as a biocontrol agent against multidrug-resistant (MDR) S. aureus. Four S. aureus temperate phages were successfully isolated, and their biological features, genomic properties, and antibacterial effect against S. aureus and biofilm were characterised. Phage SapYZUs891 exhibited relatively high titre (1.7 × 1010 PFU/mL), short latent period (5 min), large burst size (554 PFU/cell), strong pH (4-10) and thermal stability (25-70 °C), and a broad lytic spectrum (47.3%, 43/91; p ≤ 0.05). Comparative genomic analysis suggested that SapYZUs891 lacks antibiotic resistance or virulence genes, but contains unique gene content, including genes encoding DNA polymerase, DNA packaging protein, holin, and tail fibre protein. Notably, SapYZUs891 significantly inhibited biofilm formation (28.3%-70.6%, p < 0.01), scavenged mature S. aureus biofilms (36.9%-61.5%, p < 0.001) and reduced the counts of S. aureus (1.14 - 1.40 Lg CFU/mL, p ≤ 0.01) in milk at 4°C. Furthermore, SapYZUs891 effectively reduced the minimum inhibitory concentrations of MDR S. aureus against antibiotics by 2 - 64 folds (p ≤ 0.05). Therefore, the temperate phage SapYZUs891 with attractive biological properties, genetic features and antibacterial potential is an effective biocontrol agent against MDR S. aureus.

      This study investigated the efficacy and safety of a novel thermo-reversible antimicrobial wound gel (TRG, revyve Antimicrobial Wound Gel) designed to combat biofilm-related infections in wounds. The TRG was evaluated for its ability to disrupt biofilms, sustain antimicrobial activity and promote wound healing. The gel exhibited thermo-reversible properties, transitioning from a less viscous liquid ≤ 18°C to a highly viscous solid gel at wound temperature which would facilitate easy application and removal. Antimicrobial testing demonstrated that TRG effectively inactivated a broad range of wound-related pathogens, including Staphylococcus aureus and Pseudomonas aeruginosa, with a 99.99%-99.9999% reduction in bacterial counts within 30 min. The TRG also maintained its antimicrobial efficacy after multiple inoculations with high microbial load (107 CFU/mL) over 7 days. In vitro biofilm assays showed effectiveness against biofilm bacteria with a reduction of ≥ 99.99% bacterial counts with one application over the course of 7 days. Biocompatibility testing confirmed that TRG was safe, with no signs of tissue necrosis or signs of tissue damage and no impact on wound healing in a porcine wound model. TRG's ability to reduce both planktonic and biofilm-based bacteria without compromising wound healing makes it a promising candidate for treating both chronic and acute wounds.

      Leuconostoc mesenteroides is crucial to kimchi fermentation and is increasingly used as a vegetable fermentation starter culture. Although bacteriophages are abundant in kimchi, little is known about those infecting L. mesenteroides or their impact on fermentation. Here, we report three novel Caudoviricetes phages (ΦLM0121_01, ΦLM0121_03, and ΦLM0121_04) isolated from kimchi using starter strain WIKIM 0121, showing < 80% intergenomic similarity to known Leuconostoc phages. The phages had an optimal MOI of 1, burst sizes of 50.37-94.57 PFU/cell, and > 90% adsorption within 15 min. They remained viable at 50 °C, pH 4-10, and salinity up to 6%, with ΦLM0121_03 and ΦLM0121_04 retaining viability at 70 °C. Viability decreased significantly in fermented kimchi juice compared to simulated conditions, suggesting that microbial metabolites and food-derived compounds influence stability. These findings advance understanding of Leuconostoc phage biology and support the development of phage control strategies and resistant starter cultures for fermented foods.

      Autoimmune blistering diseases (AIBDs), including pemphigus vulgaris (PV) and bullous pemphigoid (BP), are characterized by painful erosions and chronic wounds that significantly impair patient quality of life. While systemic therapies remain the cornerstone of treatment, optimal strategies for local management, including wound care and topical therapies, are not well defined. The aim of this study is to review and synthesize current evidence on topical treatments and wound care strategies in AIBDs, with a focus on their role in disease control, infection prevention, and enhancement of healing. A narrative review of the literature was conducted using PubMed-indexed articles and guidelines relevant to topical corticosteroids, calcineurin inhibitors, antiseptics, antibiotics, and wound dressings in the management of PV, BP, and related disorders. Topical corticosteroids, particularly clobetasol propionate, are the first-line treatment for BP and play an adjunctive role in PV. Topical calcineurin inhibitors have shown promise as steroid-sparing agents in localized disease, though evidence remains limited. Antiseptics such as chlorhexidine may aid in infection control, though clinical data are sparse. Topical antibiotics like mupirocin and fusidic acid might be used in case of secondary infection or critical colonization. Dressing selection-favoring non-adherent, antimicrobial, or moisture-retentive options-is crucial to minimize trauma, promote healing, and prevent complications, particularly in elderly or high-risk patients. Topical therapies and wound care are essential components in the management of AIBDs but remain understudied and poorly standardized. Evidence supports the use of high-potency corticosteroids in BP and adjunctive use in PV, while promising data on antiseptics and advanced dressings warrant further investigation. Well-designed clinical trials are needed to establish evidence-based guidelines in this setting.

      The rise of multidrug-resistant (MDR) bacterial pathogens presents a critical challenge to global health, highlighting the need for innovative therapeutic strategies beyond conventional antibiotics. Antibody-antibiotic conjugates (AACs) combine the high specificity of monoclonal antibodies with the potent bactericidal activity of antibiotics, offering targeted delivery to extracellular and intracellular bacteria while minimizing off-target toxicity. The present review provides a comprehensive analysis of AAC development, including key components, such as antigen selection, antibody engineering, linker chemistry, antibiotic payload optimization, and bioconjugation strategies. We summarize the mechanistic principles underlying AAC-mediated bacterial clearance, emphasizing targeted payload release, fragment crystallizable region of the antibody (Fc)-mediated immune engagement, and intracellular delivery. The temporal evolution of AACs is examined, highlighting milestones from early proof-of-concept studies to modern site-specific, humanized constructs and emerging bispecific or dual-payload designs. Furthermore, clinical development is discussed, focusing on pharmacokinetics, pharmacodynamics, safety, efficacy, and regulatory considerations, for example, intracellular infections and biofilm-associated infectious agents. Current challenges, including antigen heterogeneity, immunogenicity, linker-payload optimization, and manufacturing scalability, are critically analyzed, alongside strategies for next-generation AACs. Collectively, AACs represent a transformative platform for precision-targeted antimicrobial therapy, bridging gaps left by conventional antibiotics and offering a promising approach to combating MDR bacterial infections and associated clinical complications.

       BACKGROUND: Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), is a chronic disorder marked by intestinal inflammation and immune dysregulation. While bacterial dysbiosis has been widely investigated, the gut virome remains less explored. Altered viral communities, particularly bacteriophages, may destabilize microbial balance and amplify host inflammation.
    METHODS: To characterize virome alterations, we conducted a cross-sectional observational study in Tabriz, Iran, involving fifty participants divided into five groups: mild UC, severe UC, mild CD, severe CD, and healthy controls. Stool samples were processed for viral nucleic acid extraction and analyzed using metagenomic next-generation sequencing. Bioinformatics pipelines included diversity assessment, taxonomic profiling, functional annotation, and discriminant analysis (LEfSe). Predictive modeling was performed with random forest classifiers.
    RESULTS: Virome richness and diversity were reduced in severe UC and CD compared with controls, whereas mild cases showed values closer to healthy individuals. Taxonomic profiling revealed depletion of crAss-like phages and microviridae in IBD, along with enrichment of Caudovirales families such as siphoviridae and myoviridae. Among eukaryotic viruses, anelloviridae were prominent in severe IBD, and herpesviridae were enriched specifically in severe UC. Functional annotation highlighted enrichment of structural and lytic phage proteins in severe groups, whereas lysogeny-associated domains were more abundant in healthy controls. Random forest models based on viral features achieved appropriate accuracy, with an AUC of 0.89 for distinguishing IBD from controls and 0.83 for classifying mild versus severe disease.
    CONCLUSION: Thus, IBD is associated with reduced virome diversity, loss of core protective phages, and selective enrichment of bacteriophages and eukaryotic viruses. These findings suggest that virome features may have potential as biomarkers for non-invasive diagnosis and severity stratification in IBD, requiring validation in larger and longitudinal cohorts.

      Bromelain-based enzymatic debridement (BBD) may selectively remove devitalised tissue in chronic wounds, but randomised evidence is limited. Following PRISMA and a PROSPERO-registered protocol (CRD420251116455), we searched MEDLINE, CENTRAL and Embase from inception to 8 Aug 2025 for randomised controlled trials in adults with chronic wounds comparing topical BBD versus standard care/vehicle. Two reviewers screened, extracted and assessed risk of bias. Primary outcomes were incidence of complete debridement (efficacy) and ≥ 1 adverse event (safety). Of 24 records, 3 RCTs (n = 314) met inclusion; 2 contributed complete-debridement data and 3 contributed adverse-event data. BBD increased complete debridement versus control (RR 2.81, 95% CI 1.15-6.86; I2 = 58.7). Safety was comparable (RR 1.02, 95% CI 0.76-1.36; I2 = 0), and leave-one-out analyses for adverse events showed no influential study. BBD improves the likelihood of complete debridement without increasing adverse events, suggesting a possible role in its use as a selective, non-surgical adjunct alongside guideline-directed care.

      Background Porphyromonas gingivalis (P. gingivalis) is a key pathogen in chronic periodontitis that drives dysbiosis and tissue destruction. Anaerobic culture often underestimates fastidious bacteria, whereas real-time polymerase chain reaction (RT-PCR) can provide higher sensitivity and accurate quantification. This study compared both methods for detecting and quantifying P. gingivalis in subgingival plaque from patients with chronic periodontitis and healthy controls. Methodology In total, 32 participants (16 with chronic periodontitis and 16 healthy) were included. Pooled subgingival plaque samples were analyzed by anaerobic culture on selective media and by RT-PCR targeting the 16S rRNA gene with a TaqMan probe and standard curve quantification. Clinical parameters were recorded (probing depth (PD), clinical attachment loss (CAL), and gingival index (GI)), and data were analyzed using t-tests, chi-square tests, Pearson's correlation, and diagnostic metrics. Results Participants with chronic periodontitis had significantly higher clinical parameters (PD = 6.38 ± 0.96 mm, CAL = 3.63 ± 1.09 mm, GI = 2.50 ± 0.22; all p = 0.001) and P. gingivalis loads (culture = 82.13 ± 54.26 CFU/mL, p = 0.031; RT-PCR = 97.44 ± 59.02 CFU equivalents/mL, p = 0.039) than controls. Bacterial load showed moderate positive correlations with clinical parameters (r = 0.35-0.42, p < 0.05). RT-PCR detected P. gingivalis in 59.4% of samples versus 50% by culture, achieving 100% sensitivity and 90.6% accuracy. Conclusions RT-PCR is more sensitive than culture for P. gingivalis detection, supporting its use for improved periodontal diagnosis and risk assessment.

       BACKGROUND: Chronic diabetic wounds are often complicated by biofilm-forming, antibiotic-resistant pathogens such as Staphylococcus aureus and Acinetobacter baumannii, which delay healing. This study evaluated the synergistic effects of gentamicin and imipenem in combination with fucoidan, a sulfated polysaccharide from brown seaweed, against dual-species biofilms in a diabetic rat wound model.
    METHODS: Methicillin-resistant S. aureus (MRSA) strain 6 and A. baumannii strain 1, isolated from diabetic foot ulcers, were used to establish dual-species biofilms in vitro and in vivo. Excisional wounds were created in male Wistar rats with streptozocin-induced type II diabetes and infected with the biofilms. Rats received daily treatments of gentamicin, imipenem, their combination, or the triple combination with fucoidan. Outcomes assessed included bacterial load (CFU/g), biofilm formation, expression of biofilm-related genes (icaA and bap by real-time PCR), wound size, and histological healing parameters.
    RESULTS: The triple therapy demonstrated the strongest antibacterial effect, reducing bacterial load by more than 4 log₁₀ CFU/g compared to controls (p < 0.005). Real-time PCR revealed significant downregulation of icaA in S. aureus (threefold decrease) and bap in A. baumannii (fourfold decrease) relative to antibiotic-only groups (p < 0.005). Histology showed accelerated wound contraction and complete re-epithelialization by day 14 with the triple combination, whereas monotherapy or dual antibiotics led to delayed healing and persistent inflammation.
    CONCLUSIONS: Fucoidan enhances the efficacy of gentamicin and imipenem against biofilm-associated infections and promotes diabetic wound healing. This combinatorial approach offers a promising strategy for managing chronic, biofilm-infected wounds and combating antibiotic resistance.

      Diabetic wounds remain a major clinical challenge due to bacterial infection, persistent inflammation, and excessive accumulation of reactive oxygen species (ROS). This highlights the urgent need for wound dressings that provide sustained antibacterial effects, stable ROS scavenging, and effective immune modulation. To this end, we developed a multifunctional electrospun polyvinyl alcohol-chitosan (PVA-CS) nanofibrous dressing by integrating black phosphorus nanosheets (BPNSs) with polydopamine-coated zinc oxide nanoparticles (PDA@ZnO NPs). This dressing achieved synergistic photothermal-Zn2+ ion antibacterial activity, rapidly reducing the viability of MRSA, MSSA, and E. coli, along with their biofilms, to 0-2% in 3 min while enabling Zn2+ release to support a sustained antibacterial microenvironment. The dresssing also provided sustained ROS scavenging due to stabilized BPNSs, with intracellular ROS levels reduced to 13-20%, accompanied by an overall 50-70% improvement in antioxidant capacity, thereby alleviating oxidative stress and suppressing inflammation. In addition, ZnO NPs also promoted anti-inflammatory macrophage polarization, accelerated tissue healing, and supported natural repair processes. This work introduces a multifunctional wound dressing with rapid and sustained antibacterial, antioxidative, and anti-inflammatory properties, offering a promising solution for chronic diabetic wounds.

      Biofilm-associated infections exhibit high tolerance to antibiotics and antimicrobials, posing a significant challenge to wound management. Pseudomonas aeruginosa and Staphylococcus aureus are among the most prevalent pathogens in biofilm-associated wound infections. Here, we report a main-chain cationic antimicrobial polymer, poly(butylimidazolium) (PIM1), whose imidazolium units feature an acidic C2-H carbon center. PIM1 demonstrated potent broad-spectrum activity against multidrug-resistant (MDR) bacteria with minimal cytotoxicity toward multiple mammalian cell lines in vitro. PIM1 retained fast bactericidal activity under physiological conditions, including whole blood and high bacterial inoculum. Interestingly, its potency increased 2- to 4-fold in the presence of serum. PIM1 also eliminated antibiotic-tolerant persister cells and eradicated biofilms formed by MDR pathogens. In vivo, 7-day continuous topical administration of PIM1 on murine wounds caused no observable toxicity. In murine excisional wound infection models, topical PIM1 treatment achieved >99% eradication of P. aeruginosa and S. aureus biofilms, outperforming imipenem and vancomycin controls, respectively. These findings support PIM1 as a safe and effective therapeutic candidate for treating biofilm-associated wound infections caused by MDR bacteria.

       Background: The National Institute for Health and Care Excellence (NICE) introduced the world's first 'subscription-type' antimicrobial payment model in the UK in 2022 for ceftazidime-avibactam and cefiderocol, decoupling reimbursement from usage to stimulate innovation. The model is being expanded to additional antimicrobials. We aimed to explore the views of lead antimicrobial stewardship (AMS) pharmacists, key model implementers and stakeholders, using a nationwide survey.
    Methods: An online survey was distributed to lead AMS pharmacists of NHS acute Trusts (n = 131) in England (February-July 2025).
    Results: Forty-three pharmacists (response rate 32.8%) participated. Most were familiar with the model (86.1%) and supported its principle (88.4%), believing it promotes stewardship and innovation. Strong support existed for model expansion to antifungals, antivirals and novel modalities such as phage therapy.Key priority pathogens for candidate drugs included carbapenem-resistant Pseudomonas aeruginosa, carbapenem-resistant Acinetobacter baumannii and carbapenem-resistant Enterobacterales. Respondents prioritized candidate drugs with oral or once-daily intravenous administration. Over half (51.2%) favoured empirical use in high-risk patients, the remainder would restrict novel antimicrobials to microbiologically-proven infections. Top risk factors for empirical use included previous infection/colonization with carbapenem-resistant bacteria and carbapenem treatment failure.Aseptic preparation requirements were the major practical barrier, rather than drug monitoring, storage or interaction management. Median fair price for Trust contribution was 50% of the list cost.
    Conclusions: AMS pharmacists view the subscription model positively but highlight the need to refine product award criteria to reflect clinical implementation priorities. Their insights are critical to optimizing future delinked payment models and ensuring equitable access to novel antimicrobials.

      Bacillus anthracis spores can remain viable for many years in regions where anthrax cases are reported or where deceased animals are buried. Anthrax occurrences may be more common in areas where livestock farming is a primary source of livelihood. In this study, 43 Bacillus anthracis isolates were used, which were isolated from samples collected in different provinces of Türkiye. Three lytic bacteriophages(BaTR8, BaTR13, and BaTR16) were isolated from environmental soil samples. These three lytic bacteriophages' biological properties (host range, burst size, and phage morphology) were defined, and molecular methods were used to determine their genomic structures. It was determined that three lytic phages were able to infect 84.1% of the host bacteria and formed clear phage plaques. Transmission electron microscopy (TEM) analysis identified them as siphoviruses. Bacteriophage genome lengths ranged from 35587 to 37369kb, and the GC content was approximately 35%. The genome structures of the three phages were analyzed, determining that they contained 58-62 ORFs and did not encode any tRNA genes. Phylogenetic analyses of the bacteriophages were performed based on whole-genome sequences and conserved signature genes (major capsid, portal, and terminase large subunit proteins), and the phages were taxonomically classified within the class Caudoviricetes. The three phages isolated in this study, together with the Athena phage, which infects Bacillus anthracis, were determined to form a new cluster distinct from the Wbetavirus and Hubeivirus genera. Our study presents, for the first time, the results of a detailed evaluation of Bacillus anthracis phages isolated from Türkiye.

       BACKGROUND AND OBJECTIVES: Antimicrobial resistance (AMR) represents a critical and escalating global health threat, with resistant bacterial infections contributing to millions of deaths annually. While the development of novel antibiotics remains essential, preventive strategies, particularly vaccination, offer a sustainable and underutilized approach to mitigating AMR. This review aims to provide a comprehensive overview of vaccine development efforts targeting bacterial pathogens listed in the World Health Organization (WHO) 2024 Priority Pathogens report.
    METHODS: We systematically analyzed both preclinical and clinical-stage vaccine candidates, focusing on platform technologies, antigen selection strategies, and pathogen-specific challenges.
    RESULTS: Advances in mRNA platforms, outer membrane vesicles, reverse vaccinology, and structure-guided antigen design are accelerating vaccine development. However, significant challenges persist, including antigenic diversity, limited correlates of protection, and regulatory complexity.
    CONCLUSION: Vaccination represents a promising strategy to reduce antibiotic use and limit resistance prevalence. By integrating current pipeline data with AMR reduction frameworks, this review provides an updated resource to guide vaccine design, investment prioritization, and global AMR control strategies.

      Eye infections are a significant area of microbial adaptation and therapeutic challenge, as antibiotic resistance threatens vision. In the last ten years, our knowledge of the ocular resistome has expanded through genomics and molecular epidemiology. An analysis of global evidence from 2015 to 2025 on the resistance architecture of major ocular pathogens will be presented, with a focus on Pseudomonas aeruginosa (P. aeruginosa). The organism shows remarkable genomic flexibility by incorporating intrinsic resistance elements, biofilm-mediated tolerance, and by acquiring ARGs such as blaVIM, blaGES, QnrVC and RmtB by horizontal transfer. According to researchers, Staphylococcus aureus (S. aureus), Streptococcus pneumoniae (S. pneumoniae), and Acinetobacter baumannii (A. baumannii) have evolved mechanisms of drug resistance. Geographic analysis shows regional disparities, particularly in South Asia and North America, which are associated with antibiotic use and clinical exposure. To prevent the emergence of ocular antimicrobial resistance, there's an urgent need for rapid molecular diagnostics, genomic-based surveillance, and responsible antimicrobial stewardship.

      Normal wound healing is a complex, yet critical process. Unfortunately, delayed or impaired wound healing presents a significant burden for numerous patients worldwide. Recent research has demonstrated that exosomes, a subtype of extracellular vesicles, may play a pivotal role in mediating cell-cell communication during wound healing. This narrative review aims to explore the use of exosomes in wound healing, with a focus on in vivo application of exosomes in animal wound models. A total of 73 studies are outlined in this narrative review, exploring either excisional, diabetic, burn, ischemic, or pressure wounds. Overall, the most frequent source of exosomes was adipose-derived mesenchymal stem cells, and the most common application method was local or subcutaneous injection. While these studies demonstrated great promise for the use of exosomes for therapeutic use in wound healing, this review also discusses the challenges and obstacles that will need to be overcome, including standardizing methods, further characterizing exosomes and identifying the optimal sources and doses in the development of exosome therapies.

      Cystic fibrosis (CF) has transitioned from a disease predominantly affecting the pediatric population to a chronic disease of adulthood. As patients with CF continue to prolong their survival with CFTR modulator therapy, there has become increased relevance of age-related endocrine, metabolic, and cardiovascular complications. Endocrinopathies in this population include but are not limited to diabetes, bone disease, menopause, and obesity. In this review, we summarize the current evidence on these endocrine and metabolic complications, emphasizing the importance of early screening, multidisciplinary management, and continued efforts to address the evolving health and quality-of-life needs of an aging CF population including the need for CF-specific population based studies to adapt current clinical practice guidelines that remain targeted towards the general population.

      Diabetic foot ulcer (DFU) remains a major cause of morbidity and lower-limb amputation worldwide. Accurate risk assessment and timely intervention are critical for improving healing outcomes. A recent study identified the decapping scavenger enzyme (DCPS), an N7-methylguanosine (m7G)-related gene, as a potential diagnostic and therapeutic biomarker for DFU. Reduced DCPS expression was found to impair keratinocyte proliferation, migration, and cell-cycle progression, highlighting its possible role in m7G-mediated wound repair. Despite these promising insights, several challenges must be addressed before DCPS can be translated into clinical practice. First, DCPS expression may vary among patients with metabolic or inflammatory disorders, limiting its disease specificity. Second, standardized reference ranges for DCPS quantification have not yet been established. Moreover, whether DCPS modulation can directly enhance wound healing remains uncertain. Overall, DCPS provides a novel mechanistic link between RNA methylation and chronic wound pathology, but its clinical application as a biomarker or therapeutic target warrants careful validation.

      Failure to resolve the neutrophilic inflammation during the innate immune response results in neutrophil accumulation in the airways. These cells exhibit prolonged survival, increased necrosis, and impaired phagocytic capacity. Paradoxically, despite reduced pathogen-clearing ability, neutrophils release serine proteases that drive the destruction of airway tissue. Their persistence in the lung chronically promotes a cycle of tissue damage, remodeling, and inflammation, leading to progressive pulmonary dysfunction. Recent discoveries in neutrophil dysregulation open up the possibility of developing more targeted, disease-specific therapies, potentially revolutionizing the treatment of diseases like cystic fibrosis, chronic obstructive pulmonary disease, bronchiectasis, and asthma, where current treatments remain largely generalized and ineffective. This review explores the complex relationship between neutrophil dysregulation and disease progression, highlighting the different roles that neutrophils play across various lung diseases, and will summarize current strategies to target key pathways. Understanding these pathways could inform the development of therapeutic strategies to effectively mitigate neutrophil-driven inflammation to improve the clinical outcome.

       INTRODUCTION: Interindividual variability in drug response remains a significant clinical challenge, leading to therapeutic failure and toxicity. Much of this variability is unexplained by classical host-centric pharmacokinetic (PK) models, highlighting a critical gap in understanding of drug disposition. This review addresses this gap by establishing the gut microbiome as an important determinant of drug fate.
    AREAS COVERED: This narrative review with scoping approach examines how microbial enzymes affect therapeutics through comprehensive analysis of mechanistic and clinical studies. Key examples discussed include irinotecan, digoxin, and sulfasalazine. We highlight specific situations where the influence of gut bacteria is particularly significant, such as with low-bioavailability drugs and in patients with an ileocolonic anastomosis, where gut bacteria directly impact drug absorption and metabolism. Additionally, we address the limitations of current PK models and explore the potential of new integrated approaches.
    EXPERT OPINION: We propose that the gut microbiome should be recognized as a 'fifth pillar' of PKs. This shift in perspective is crucial for advancing personalized medicine. In this new model, a 'PK profile card' integrating microbial, genomic, and clinical data will help guide dosing. We anticipate microbiome analysis to become a standard clinical tool to optimize drug efficacy and safety.

      Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare, life-threatening mucocutaneous reactions. Pediatric mortality is lower than in adults, but children face higher risks of recurrence and long-term sequelae. Despite disease severity, pediatric-specific guidelines remain scarce and often extrapolated from adult populations. We systematically reviewed and appraised national and international clinical practice guidelines and consensus statements on pediatric SJS/TEN, focusing on supportive care, pharmacologic interventions, mucosal management, and long-term follow-up. A systematic search of MEDLINE, Embase, PubMed, CENTRAL, Scopus, and CINAHL (January 2000-April 2025) identified national and international guidelines. For feasibility, we restricted full appraisal to documents published in English or French. Eligible documents provided explicit recommendations for patients < 18 years. Two reviewers independently extracted data and assessed quality using the AGREE II instrument. Of 144 records screened, 10 guidelines met inclusion criteria; 60% were published within the last 5 years, and 50% were consensus-based without systematic evidence synthesis. Most (90%) endorsed supportive measures such as wound care, nutritional support, and fluid resuscitation. Recommendations for pharmacologic therapy varied considerably: intravenous immunoglobulin (50%), systemic corticosteroids (40%), and cyclosporine (40%), with limited pediatric dosing guidance. Only one guideline mentioned biologics. Multidisciplinary care was recommended in 90%, yet long-term follow-up for sequelae appeared in only 50%. AGREE II appraisal showed high clarity of presentation but consistently low applicability; only the British Association of Dermatologists guideline achieved high quality across all domains. Current pediatric SJS/TEN guidelines display heterogeneity in scope and rigor. While supportive care is emphasized, pharmacologic and long-term management guidance remains inconsistent. Standardized, evidence-based, pediatric-specific guidelines are urgently needed.
