This study reported a the multidrug-resistant Salmonella 4,[5],12:i:- isolate harboring mcr-1, bla CTX-M-14 and fosA3 from human for the first time in China. The occurrence of mcr-1 and fosA3 genes in the transferable IncHI2 plasmid pYZU1189 from the ESBL-producing Salmonella 4,[5],12:i:- isolate showed a potential threat to public health.
