New superbug in China threatens to defeat last-resort antibiotics
statnews.com

November 18, 2015

Experts have been warning for a while that the bell is tolling for the end of the antibiotic era, presaging a time when infections won’t be treatable with the drugs that have changed modern medicine. On Wednesday, that ominous knell got a little bit louder.

Chinese and British scientists reported that they have found a strain of Escherichia coli that is resistant to colistin, the antibiotic of last resort for gram-negative bacteria such as E. coli. The resistant bacteria were found in pigs, raw pork meat, and in a small number of people in China.

It’s not the first time colistin resistance has been spotted, but this time the phenomenon comes with a nasty twist. The resistance is conferred by a gene found on a plasmid, a portable piece of DNA. That’s alarming because plasmids can both transfer within a family of bugs and to other families of bacteria as well.
