CDC warns of rise in ‘nightmare bacteria’ - The Washington Post

CDC says ‘nightmare bacteria’ a growing threat

By , Published: March 5

Federal officials warned Tuesday that “nightmare bacteria” — including the deadly superbug that struck a National Institutes of Health facility two years ago — are increasingly resistant to even the strongest antibiotics, posing a growing threat to hospitals and nursing homes nationwide.
Thomas Frieden, director of the Centers for Disease Control and Prevention, said at a news conference: “It’s not often that our scientists come to me and say we have a very serious problem and we need to sound an alarm. But that’s exactly what we are doing today.”
He called on doctors, hospital leaders and health officials to work together to stop the spread of the infections. “Our strongest antibiotics don’t work, and patients are left with potentially untreatable infections,” he said.
Although the bacteria, known as Carbapenem-Resistant Enterobacteriaceae, or CRE, haven’t spread to the wider community — like some other germs — they are more dangerous, said Frieden, who described them as a “triple threat.”
First, the bacteria are resistant to all or nearly all antibiotics, even those of last resort, he said. Second, they kill up to half of patients who get bloodstream infections from them. And third, the bacteria can transfer their antibiotic resistance to other bacteria within the family, potentially making other bacteria untreatable, as well.
For example, carbapenem-resistant Klebsiella, which caused the NIH outbreak, “can spread the genes that destroy our last antibiotics to other bacteria, such as E. coli, and make E. coli resistant to antibiotics also,” Frieden said.
