Dissemination of mcr-1--Carrying Plasmids among Colistin-Resistant Salmonella Strains from Humans and Food-Producing Animals, Taiwan [PublishAheadOfPrint]

We detected the colistin-resistance gene mcr-1 in four Salmonella serovars isolated from humans and animals with diarrhea. The resistance gene was carried on different plasmids. One mcr-1—carrying conjugative plasmid, a variant of pHNSHP45, was disseminated among Salmonella isolates recovered from humans, pigs, and chickens.
