The newly identified plasmid-borne colistin resistance genemcr-1 was found in aKluyvera ascorbata isolate from hospital sewage in China.mcr-1 was carried by a 57-kb self-transmissible IncI2 plasmid. Unlike in a previous report,mcr-1 was not associated with ISApl1 and was inserted into a gene encoding a putative membrane protein by an unknown mechanism. This study highlights thatmcr-1 has spread to multiple bacterial species.
