“Nightmare bacteria” with unusual resistance to antibiotics of last resort were found more than 200 times in the United States last year in a first-of-a-kind hunt to see how much of a threat these rare cases are becoming, health officials said Tuesday.
That’s more than they had expected to find, and the true number is probably higher because the effort involved only certain labs in each state, officials say.
The problem mostly strikes people in hospitals and nursing homes who need IVs and other tubes that can get infected. In many cases, others in close contact with these patients also harbored the superbugs even though they weren’t sick — a risk for further spread.
Some of the sick patients had traveled for surgery or other health care to another country where drug-resistant germs are more common.
“Essentially, we found nightmare bacteria in your backyard,” said Dr. Anne Schuchat, principal deputy director of the U.S. Centers for Disease Control and Prevention. “These verge on untreatable infections” where the only option may be supportive care — fluids and sometimes machines to maintain life to give the patient a chance to recover, Schuchat said.
Bugs and drugs are in a constant battle, as germs evolve to resist new and old antibiotics. About 2 million Americans get infections from antibiotic-resistant bacteria each year and 23,000 die, Schuchat said.
Concern has been growing about a rise in bacteria resistant to all or most antibiotics. Last year, public health labs around the country were asked to watch for and quickly respond to cases of advanced antibiotic resistance.
In the first nine months of the year, more than 5,770 samples were tested for these “nightmare bacteria,” as CDC calls them, and one quarter were found to have genes that make them hard to treat and easy to share their resistance tricks with other types of bacteria. Of these, 221 had unusual genes that conferred resistance. The cases were scattered throughout 27 states.
