ANALYSIS - Scientists in the US have discovered a strain of E.coli resistant to the antibiotic colistin in the intestine of a pig.The discovery comes at the same time as researchers at the Walter Reed Research Institute in the US identifies the first colistin resistant mcr-1 E.coli in a person.The colistin resistant E.coli discovered in the pig’s intestine has the same mcr-1 gene.It was discovered by scientists from the USDA and Department of Health and Human Services searching for colistin-resistant bacteria in food animals, retail meats and people.The HSS said that the two discoveries are of concern because colistin is used as a last resort drug to treat patients with multi-drug resistant infections.
