Cross sector comparisons remain constrained by method heterogeneity and data gaps. To operationalize One-Health monitoring, we propose (i) a two window surveillance design: late dry baseline and 24\u201372 h post-storm flood pulses; and (ii) a two tier analytics model: Tier 1 HT-qPCR ARG\/MGE panels at regional hubs for rapid screening, and Tier 2 metagenomics\/isolate whole genome sequencing (WGS) at national hubs for source attribution and plasmid tracking. We translate these findings into a modular AMR risk assessment toolkit to prioritize surveillance and targeted interventions.\n                  <\/jats:p>","DOI":"10.3389\/fmicb.2025.1711400","type":"journal-article","created":{"date-parts":[[2025,12,12]],"date-time":"2025-12-12T12:13:38Z","timestamp":1765541618000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Antibiotic Resistance in the Philippines: Environmental Reservoirs, Spillovers, and One-Health Research Gaps"],"prefix":"10.3389","volume":"16","author":[{"given":"Charmaine","family":"Ng","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josephine","family":"Abrazaldo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"de Vera","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shin Giek","family":"Goh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boonfei","family":"Tan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,12,12]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"68","DOI":"10.47895\/amp.vi0.8056","article-title":"Antimicrobial consumption and resistance of restricted antibiotics in a level III government hospital.","volume":"58","author":"Abeleda","year":"2024","journal-title":"Acta Med.
