Comparative Analysis of Antibiotic Resistance and Genomic Characteristics of <i>Enterococcus faecium</i> and <i>Enterococcus lactis</i> Along the Food Chain - 5 PLADs, China, 2015-2024.

ABSTRACT:

Introduction

Foodborne antibiotic-resistant enterococci pose significant risks to One Health and clinical antimicrobial efficacy through food chain transmission. Following the taxonomic reclassification of Enterococcus faecium (E. faecium), comprehensive long-term surveillance data on antibiotic resistance (ABR) patterns and genomic characteristics of E. faecium and Enterococcus lactis (E. lactis) across food animals, environmental sources, and human populations remain limited.

Methods

A total of 2,233 samples were collected from multiple nodes along the food chain across 5 Chinese provincial-level administrative divisions (PLADs) during 2015-2019 and 2023-2024. E. faecium (87 isolates) and E. lactis (153 isolates) were identi
