CHICAGO (Reuters) - Scientists have identified a second patient in the United States infected with bacteria carrying the mcr-1 "superbug" gene, which makes bacteria highly resistant to a last-resort class of antibiotics.
The gene, found in a sample of E. coli bacteria from a patient in New York, follows the discovery late last month of a patient in Pennsylvania who had a urinary tract infection caused by E. coli that carried the gene.

The finding was published on Monday in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.
The mcr-1 gene makes bacteria resistant to colistin, an antibiotic used to treat multi-drug-resistant infections, including carbapenem-resistant Enterobacteriaceae or CRE, which U.S. health officials have dubbed a "nightmare" bacteria.

What is concerning about the mcr-1 gene discoveries in the United States is that bacteria have the capability to share resistance genes. U.S. officials are worried that the mcr-1 gene may find its way into CRE bacteria, potentially creating bacteria resistant to virtually all types of antibiotics.
Scientists have been tracking the mcr-1 gene's movement around the globe since it was discovered last year in people and pigs in China.
