Deadly superbug arrives in US, report says

A long-dreaded superbug that is a strain of E. Coli has made its first appearance in the United States, researchers at the U.S. Military HIV Research Program announced Thursday. After being identified in China, Europe and Canada, researchers identified mcr-1 positive— part of the deadly family of bacteria carbapenem-resistant Enterobacteriaceae, or CRE— last month in a urinary tract sample in Pennsylvania, and found it was resistant to the antibiotic colistin. Colistin, known as the last line of defense against the most antibiotic-resistant bacteria, now appears to be exchanging genes for its resistance and waning in strength, according to a news release.
