This study aimed to characterize the genetic diversity and phylogenetic relationships of bla_CTX-M and bla_TEM genes in ESBL-producing E. coli isolated from hospital wastewater in Manila and Quezon City, Philippines. Seventeen isolates carrying bla_CTX-M-1, bla_CTX-M-9, and bla_TEM-1 genes, confirmed by multiplex PCR, were subjected to DNA sequencing and phylogenetic analysis alongside global reference strains. Phylogenetic analysis of the bla_CTX-M gene sequences revealed two distinct clusters: six bla_CTX-M-15 variants clustered within the CTX-M-1 clade, showing close relatedness to strains from Thailand, Iran, and neighboring Southeast Asian clinical and environmental samples, while two bla_CTX-M-27 clustered within the CTX-M-9 group, closely related to isolates from India, Australia, and Spain. All bla_TEM-1 gene sequences aligned with globally disseminated TEM-1 references. The co-occurrence of multiple ESBL gene variants in individual effluent samples underscores active horizontal gene transfer facilitated by mobile genetic elements in wastewater environments. These findings reveal substantial genetic diversity of ESBL determinants and demonstrate the convergence of clinical and environmental AMR reservoirs through hospital effluents. Incorporating genetic surveillance of hospital wastewater into national AMR action plans can enhance detection of emerging resistance variants, inform risk assessment, and guide targeted interventions to mitigate environmental dissemination. Future work should integrate whole-genome sequencing to elucidate plasmid dynamics and resistance gene mobilization mechanisms, advancing One Health strategies to curb the AMR threat.</p>","PeriodicalId":51027,"journal":{"name":"Ecohealth","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148177134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed framework encompasses four key dimensions-social governance, behavioral control, health system adjustments, and environmental governance-designed to align health priorities across sectors and scales. By incorporating multi-sectoral collaboration, evidence-based risk factor analysis, and multidimensional health indicators, this model offers actionable strategies for enhancing health equity, system resilience, and long-term sustainability.

The use of a systems thinking, Ecohealth approach for understanding the dynamic linkages between all the ecological, biological, and social (eco-bio-social) factors associated with DENV epidemiology is imperative to better understand the DENV epidemiological system (episystem). The aim of this scoping review was to summarize the evidence for the relationships between the eco-bio-social factors influencing DENV vector dynamics, transmission, and epidemiological outcomes in LAC. The PubMed, SCOPUS, and LILACS databases were searched to collect relevant papers irrespective of design published in English, French, Portuguese, or Spanish. Full-text articles were obtained for the studies that passed the title and abstract screening process. The full-text articles were evaluated to determine if they met the eligibility criteria. Data were extracted using NVivo™ 12, and themes were compiled and communicated narratively. We included 68 studies from 13 different countries from LAC from the published literature from LAC between 2007 and 2022. Studies were classified as eco-biological (n = 24), bio-social (n = 21), eco-social (n = 14), or eco-bio-social studies (n = 9). Ten determinants emerged from the literature and were described, including: temperature; precipitation and humidity; artificial environment; vegetation and land cover; elevation and altitude; human population mobility and human activity; human population density and population demographics; chemical protective measures; seasonality and water storing practices; and urbanization and land use changes. We summarized the evidence on the eco-bio-social determinants of dengue transmission in LAC, with implications for comparable contexts in Asia and Africa.

Resistant organisms and genes move freely across humans, animals, food systems, and the environment, with wastewater, soil, and wildlife acting as critical reservoirs. This interconnectedness highlights the need for a coordinated One Health framework that recognises AMR as both a medical and ecological crisis. In this review, we examine the mechanisms driving the emergence and dissemination of AMR and explore how stewardship, ecological management, and policy interventions can be integrated to mitigate its spread. We particularly consider how selective pressures operating across clinical and environmental settings influence resistance persistence and transmission. Evidence shows that judicious antimicrobial use in healthcare and veterinary medicine, coupled with environmental safeguards such as wastewater management and effluent regulation, can reduce selective pressure and transmission risk. Case studies illustrate how coordinated surveillance across sectors provides early warning of emerging resistomes, while stewardship programmes prolong the efficacy of existing antibiotics. Together, these findings highlight the importance of integrated responses that address resistance across interconnected human, animal, and environmental systems. By situating AMR within the broader human-animal-environment interface, this review underscores the critical importance of ecological thinking in designing sustainable solutions.
