Abstract
<p>Global spread of the plasmid-mediated colistin resistance gene, mcr-1 poses a challenge to public health because colistin is the last-line-of-defense against severe infections of multidrug-resistant Gram-negative bacteria. In Japan, a few studies have reported the prevalence of mcr-1 among food animal-derived Escherichia coli isolates, but the prevalence of mcr-1 in retail meats is not well known. We report here the first detection of mcr-1 in retail chicken meat. A total of 70 extended-spectrum beta-lactamase-producing E. coli isolates, recovered from retail chicken meats between August 2015 and June 2016, were screened for mcr-1. We found 1 CTX-M-1 beta-lactamase-producing E. coli isolate belonging to ST1684, phylogroup A. The mcr-1 gene was not located on an IncI1 plasmid encoding the blaCTX-M-1 gene. However, whole plasmid sequencing revealed that mcr-1 was located on an IncI2 plasmid. The sequences of the nikB-mcr-1-pap2-ydfA-topB region of the IncI2 plasmid in this study was almost identical to that of the previously described IncI2 plasmid, pECJS-61–63 present in E. coli isolated from pig feces in China, except for containing a synonymous mutation in the mcr-1 gene. Plasmid carrying the mcr-1 gene have not yet been identified in human isolates in Japan. Thus, strict monitoring or surveillance of colistin resistance among Gram-negative bacteria recovered from retail meat of food animals under colistin pressure, and humans, is crucial.</p>
