An endemic multi-drug resistant ST117 E. coli isolate coproducing MCR-1 and 3 ESBL loci was, for the first time, detected from diseased chicken, Liaoning Province, in Northeast China, from 2011 to 2012. Whole-genome sequencing revealed 5 unique plasmids, namely pHXH-1, pHXH-2, pHXH-3, pHXH-4 and pHXH-5). Among them, pHXH1 and pHXH4 encode ESBL, and pHXH-5 mediates MCR-1 colistin resistance. The results indicate that the potentially-national dissemination of MCR-1-positive pathogens with pan-drug resistance proceeds via food chains.
