Complete Genomic Analysis of a Salmonella enterica Serovar Typhimurium Isolate Cultured From Ready-to-Eat Pork in China Carrying One Large Plasmid Containing mcr-1.

ABSTRACT: One mcr-1-carrying ST34-type Salmonella Typhimurium WW012 was cultured from 3,200 ready-to-eat (RTE) pork samples in 2014 in China. Broth dilution method was applied to obtain the antimicrobial susceptibility of Salmonella Typhimurium WW012. Broth matting assays were carried out to detect transferability of this phenotype and whole-genome sequencing was performed to analyze its genomic characteristic. Thirty out of 3,200 RTE samples were positive for Salmonella and the three most frequent serotypes were identified as S. Derby (n = 8), S. Typhimurium (n = 6), and S. Enteritidis (n = 6). One S. Typhimurium isolate (S. Typhimurium WW012) cultured from RTE prepared pork was found to contain the mcr-1 gen
