Explanation: The MCR-1 is a genetic mechanism by which the mcr-1 gene confers the first known plasmid-mediated resistance to colistin, a polymixin and one of a number of last-resort antibiotics. This mechanism was first discovered in E. coli (strain SHP45) from a pig but it was later found by independent researchers in human samples. MCR-1 is the first known polymixin resistance mechanism capable of horizontal gene transfer.
