Escherichia fergusonii, an Underrated Repository for Antimicrobial Resistance in Food Animals.

ABSTRACT: A total of 1,400 samples of food animals (pigs, chickens, and ducks) were collected between July and September 2019 in China to uncover the prevalence of E. fergusonii and its potential role in the evolution of antimicrobial resistance (AMR). An isolation of E. fergusonii was performed and pulsed-field gel electrophoresis (PFGE) was used to uncover the genetic relationship. The AMR of E. fergusonii isolates was comprehensively characterized using broth microdilution-based antimicrobial susceptibility testing, S1-PFGE, southern hybridization, whole-genome sequencing, and in-depth bioinformatics analysis. As a result, a total of 133 E. fergusonii isolates were obtained. These isolates could be grouped into 41 PFGE subclades, suggesting a diverse genetic relationsh
