Dissemination of mcr-1-Carrying plasmids among colistin-resistant salmonella strains from humans and food-producing animals, Taiwan

[[abstract]]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
