Tibetan pigs represent a substantial reservoir of MDR E. coli, strengthening the rationale for farm-level antimicrobial stewardship and integrated surveillance that links animal, environmental and human compartments. The study is limited by its cross-sectional design, focus on a single province and animal host and the absence of parallel human or environmental isolates, which prevent inference of causal zoonotic pathways and should be addressed in longitudinal One Health investigations.
Luo et al. (Fri,) studied this question.
