Zoonotic Transmission of<i>mcr-1</i>Colistin Resistance Gene from Small-Scale Poultry Farms, Vietnam

Abstract

We investigated the consequences of colistin use in backyard chicken farms in Vietnam by examining the prevalence of mcr-1 in fecal samples from chickens and humans. Detection of mcr-1-carrying bacteria in chicken samples was associated with colistin use and detection in human samples with exposure to mcr-1-positive chickens.
