However, the role of bats in AMR dissemination remains poorly understood. We conducted a cross-sectional study to investigate the prevalence and risk factors associated with AMR patterns in <em>Staphylococcus</em> spp. and <em>Escherichia coli</em> isolated from frugivorous bats in Bangladesh. We collected 369 noninvasive fecal samples from <em>Pteropus medius</em> and <em>Rousettus leschenaultii</em> individual bats. Bacterial isolation was performed using selective media, biochemical tests and performed polymerase chain reaction (PCR) for confirmation of <em>Staphylococcus</em> spp. and <em>E. coli</em>. Antimicrobial susceptibility testing for antimicrobials was conducted using the Kirby-Bauer disc diffusion technique. The prevalence of <em>E. coli</em> and <em>Staphylococcus</em> spp. was 29.8 % and 28.5 % respectively. Overall, 28.2 % of <em>E. coli</em> and 26.3 % of <em>Staphylococcus</em> spp. exhibited resistance to at least one antimicrobial. Logistic regression analysis revealed that resistant <em>Staphylococcus</em> spp. colonisation was significantly higher in rural areas (OR = 2.6) and in <em>R. leschenaulti</em><em>i</em> species (OR = 2.6), while resistant <em>E. coli</em> was higher in urban areas (OR = 2.0) and in <em>P. medius</em> bat (OR = 1.7). <em>Staphylococcus</em> spp. showed the highest resistance to ampicillin (56 %), followed by clindamycin (23 %). On the other hand, <em>E. coli</em> showed the highest resistance against cefepime (16 %) followed by ampicillin (13 %). While the source of AMR bacteria in bats remains unclear, bat drinking habits on the contaminated water bodies with people and domestic animals might be source of resistant bacteria to bats. Future One Health research is recommended to understand the ecology of AMR and role of bats in the transmission of resistant bacteria across ecosystems.</div></div>","PeriodicalId":19577,"journal":{"name":"One Health","volume":"22 ","pages":"Article 101300"},"PeriodicalIF":4.5,"publicationDate":"2025-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145927067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In southern China, persistent salmonellosis cases linked to poultry and pork highlight the need for advanced genomic tools to trace contamination sources and understand transmission dynamics. This study integrates whole-genome sequencing (WGS) and spatiotemporal data to investigate the molecular epidemiology of Salmonella in Jiangxi Province, a region with high incidence of foodborne salmonellosis. Analysis of 206 Salmonella isolates (2015–2021) revealed dominant sequence types (ST34, ST19, ST155, and ST469) associated with human clinical cases and food sources. High-resolution single nucleotide polymorphism (SNP) phylogenetic analysis revealed well-supported, monophasic clades corresponding to the major sequence types. This analysis provided strong genomic evidence for zoonotic transmission, with human clinical isolates being genetically almost identical (≤5 SNPs) to isolates from poultry (ST34/ST19) and pork (ST155/ST469) sources. Clonal clusters of monophasic Typhimurium variants (77.9 % of ST34 isolates) exhibited widespread geographic distribution across 11 prefectures, and the high genetic similarity among isolates suggests potential cross-regional transmission through contaminated food supply chains. High antimicrobial resistance (AMR) rates were detected against ampicillin (68.0 %), tetracycline (61.0 %), and sulfamethoxazole-trimethoprim (54.0 %), with multidrug-resistant (MDR) strains (60.2 %) prevalent in clinical and food-derived isolates. ST34 exhibited the highest MDR prevalence (75.4 %), driven by the presence of Salmonella Genomic Island 1 (SGI1) in many isolates. The β-lactamase gene blaTEM-1 was most prevalent (60.7 %), followed by tet(A) (54.4 %), and sul2 (47.6 %). Point mutations in the quinolone resistance-determining region (QRDR), specifically in gyrA, were identified as the primary mechanism for ciprofloxacin resistance. Spatial clustering identified significant clusters in live poultry markets, slaughterhouses, and retail meat, emphasizing the role of foodborne zoonotic reservoirs.

Environmental surveillance, particularly through wastewater monitoring, has proven valuable for tracking viral circulation and variant shift during the COVID-19 pandemic, yet its application to HEV is still limited. In this review, we systematically analyzed HEV sequences across Europe, focusing on environmental sources from a genetic perspective. Of more than 13,100 HEV sequences deposited in the NCBI database, only 2.4 % (316/13,118) originated from environmental samples, including wastewater, surface water, and biosolids. Additional typing data from the literature revealed highly uneven geographic distribution, with 97 % of environmental sequences reported from Italy, France, the United Kingdom (UK), Spain, Sweden, and Germany. HEV-3 was the dominant genotype, while HEV-1 and HEV-4 were occasionally detected. Subtypes 3c and 3f were most common, but their prevalence varied across countries and sample types. Some countries, such as France, Sweden, and the UK, exhibited divergent subtype patterns between humans, animals, and environmental sources, whereas others, such as Spain and Germany, showed more consistent distributions. These findings highlight the importance of integrating clinical, veterinary, and environmental surveillance to better understand HEV transmission in Europe under a One Health framework. However, the scarcity of environmental data, technical challenges in sequencing, and lack of standardized protocols limit comprehensive assessment of HEV circulation. Expanding sequencing efforts, improving detection methods, and coordinating international surveillance frameworks will be critical to strengthen HEV monitoring and preparedness against emerging HEV threats.</div></div>","PeriodicalId":19577,"journal":{"name":"One Health","volume":"22 ","pages":"Article 101302"},"PeriodicalIF":4.5,"publicationDate":"2025-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145927023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet the resilience of such teams is being tested by neoliberal reforms that have reshaped higher education into a competitive marketplace and by managerial practices that prioritise measurable outputs over collegiality, autonomy and disciplinary breadth. The pandemic exposed the fragility of this model: laboratories closed, workloads intensified and financial pressures triggered redundancies, even as collaboration proved essential to global health responses.

It highlights funding precarity, employment insecurity, inequities and political instability as persistent challenges, and explores how performance pressures and competition can affect collaboration.

We developed a novel approach combining semi-synthetic data generation and a sliding windows model fitting routine to estimate disease transmission parameters from surveillance data and address the temporal mismatch between pathogen transmission dynamics and disease reporting. Results showed that vaccination leads to a significant reduction in buffalo mortality, with reactive and increasing vaccination campaigns having the largest impact in reducing outbreak size. Reactive and decreasing vaccination campaigns initially controlled outbreaks, but mortality increased as soon as vaccination ceased, highlighting the need for sustained, long-term vaccination. In scenarios where populations had high natural immunity, the impact of vaccination was less pronounced, though still evident, suggesting that prioritizing vaccination efforts for more susceptible populations may provide a greater return on investment in outbreak prevention and control. Simulation models can offer valuable insights into vaccination and control strategies, providing tools to compare and evaluate potential outbreak scenarios.
