Fourth Person in US Diagnosed with Bacteria Resistant to a Last Resort Antibiotic

The latest case is a 2-year-old Connecticut girl who was diagnosed earlier this year, the Centers for Disease Control and Prevention reported Friday.

She and three other Americans have been found to have E. coli bacteria that were resistant to an important medicine called colistin. Colistin is an old, powerful drug with significant side effects that is reserved for germs that already resist other important antibiotics.

Health officials have worried that the colistin-resistant bacteria will spread their special trait to bacteria already resistant to other medicines, setting the stage for true superbug infections that are impervious to all known antibiotics.

For example, researchers reported last week a worrisome case of a 76-year-old man treated in 2014 at a New Jersey hospital. In follow-up testing this year, he was found to have been infected by a germ that was resistant to both colistin and another class of antibiotics called carbapenems that are also reserved to treat especially tough bugs.

It was the first time this kind of double-resistance was reported in the U.S., though several other cases have been reported elsewhere in the world.
