Genomic epidemiology of antimicrobial resistance determinants in Chinese swine farm <i>Escherichia coli</i> isolates.

ABSTRACT:

Introduction

The extensive use of antimicrobials in pig farming has led to a significant emergence of antimicrobial resistance (AMR) among microorganisms. Given China's prominent position as the leading global swine producer, AMR in pig farming has become a focal point of debates. However, limited research has comprehensively assessed the overall status of AMR in Chinese pig farms.

Methods

Samples were collected from 31 provinces in China. E. coli was identified and isolated using McConkey's selective medium and confirmed through PCR amplification. The MIC value was determined by BD Phoenix™ M50 Automated Identification and Susceptibility device. E. coli J53 (sodium azide-resistant) was used as the recipient in conjugation transfer experiment. The phenotypic an
