Superbug gene that resists “last resort” antibiotics detected in US for the first time
The gene was discovered during routine monitoring designed to keep an eye out for new strains of drug-resistant bacteria. Genome sequencing was conducted on the microbes in 100 clinical human stool samples, taken from people in the southeastern US between 2014 and 2016. The mcr-3.1 gene was found in one sample, from a person who had contracted a Salmonellainfection after traveling to China.
