Abstract: The detection and rapid spread of colistin-resistant Enterobacteriaceae carrying the mcr-1 gene has created an urgent need to strengthen surveillance. In this study, eight clonally unrelated colistin-resistant Escherichia coli isolates carrying mcr-1 and bla <subscript>CTX-M</subscript> or bla <subscript>CMY-2</subscript> genes were isolated from commercial chicken meat in Brazil. Most E. coli strains carried IncX4 plasmids, previously identified in human and animal isolates. These results highlight a new reservoir of mcr-1 -harboring E. coli strains in South America.<br /> (Copyright © 2017 American Society for Microbiology.)
