Co-Occurrence of NDM-9 and MCR-1 in a Human Gut Colonized Escherichia coli ST1011

Abstract

Our research, to our knowledge, first reported an ST1101 <i>E. coli</i> strain with an untypeable <i>bla</i> _NDM-9-harbouring plasmid and an IncI2 <i>mcr-1</i>-carrying plasmid. The colonized <i>E. coli</i> strains potentially contribute to the dissemination and transfer of <i>bla</i> _NDM-9 and <i>mcr-1</i> to clinical isolates, which is a considerable threat to public health and should be closely monitored.
