    The gene was detected in 5.11% (58/1136) of isolates of chicken origin from 13 provinces in China. A novel variant, named , encoding an Ile-to-Val functional variant of MCR-1 was identified in a sequence type 155 (ST155) strain. An -containing IncI2 plasmid, pHeN867 (60,757 bp), was identified. The transfer of pHeN867 led to a 32-fold increase in the MIC of colistin in the recipient, exhibiting an effect on colistin resistance that was similar to that of .
