Abstract

The prevalence of Listeria monocytogenes in bovine milk from different regions of Yunnan Province, Southwest China, was investigated. The isolated strains were genotyped using pulsed-field gel electrophoresis (PFGE), and their virulence and antibiotic resistance potential analysed with whole-genome sequencing (WGS). A total of 8 L. monocytogenes strains were isolated from 4 out of 161 samples, with a detection rate of 2.48%. All strains were at least resistant to one antibiotic, and the majority of strains (75%) were multi-antibiotic resistant. The 8 strains were clustered into 3 pulsotypes, and each pulsotype contained only strains isolated from the same geographical area. One strain was selected from each pulsotype for WGS, and it was found that a total of 99 antibiotic resistance genes and 83 virulence genes were detected from the 3 strains, respectively, which indicated that L. monocytogenes isolated from bovine milk have strong antibiotic resistance and virulence potential.
