We report here a new type of plasmid that carries the mcr-1 gene, the pMCR-1-P3 plasmid, harbored in an Escherichia coli strain isolated from a pig farm in China. pMCR-1-P3 belongs to the IncY incompatibility group and is a phage-like plasmid that contains a large portion of phage-related sequences. The backbone of this plasmid is different from that of other mcr-1-carrying plasmids reported previously. Copyright © 2017 American Society for Microbiology.
