Colistin is considered the last resort for the treatment of multi-drug resistant Gram-negative bacterial infections. We studied colistin resistance and the mcr-1 gene carriage in Salmonella isolates recovered from food animals in South Korea between 2010 and 2018. Colistin resistance was found in 277 isolates, predominantly in Salmonella Enteritidis (57.1%) and Salmonella Gallinarum (41.9%). However, the mcr-1 gene was identified in only one colistin-resistant Salmonella Typhimurium (MIC = 16 µg/mL) isolated from a healthy pig. The mcr-1 carrying isolate presented additional resistance to multiple antimicrobials. The strain belonged to sequence type (ST)19 and carried various virulence factor genes that are associated with adhesion and invasion of Salmonella into intestinal epithelial cells, as well as its survival in macrophages. The mcr-1 gene was identified on an IncI2 plasmid and it was also transferred to the E. coli J53 recipient strain. The mcr-1-carrying plasmid (pK18JST013) in this study was closely related to that previously reported in S. Indiana (pCFSA664-3) from chicken in China. This is the first report of mcr-1 carrying S. Typhimurium in South Korea. The finding indicates the importance of regular screening for the presence of the mcr-1 gene in S. Typhimurium in food animals to prevent the spread to humans.
