A potential contribution of aquaculture to the emergence of mcr-1 mediated colistin resistance? New evidence coming from France
National audience The old antibiotic colistin is used since recently in human medicine as a last resort to treat infections caused by antibioticresistant Gram negative bacteria. In 2015, a Chinese team reported a disturbing discovery: horizontally transferable colistin resistance mediated by the gen...
