‘Superbug’ gene detected

Bacteria carrying the MCR-1 “superbug” gene was found in a second US patient, researchers said on Monday. The gene was detected in an isolate of Escherichia coli that was originally recovered in 2015 from a patient in New York, according to the research published in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology. Previously, Escherichia coli bacteria carrying the MCR-1 gene was identified in a urine sample from a Pennsylvania woman in May who had no recent travel records outside of the US, Xinhua news agency reported.
