CDC nightmare bacteria NDM gene.

Government scientists say infection rates from drug-resistant “nightmare bacteria” have been increasing dramatically. Centers for Disease Control and Prevention scientists say rates rose almost 70% between 2019 and 2023. They published their findings Monday in the Annals of Internal Medicine. A subgroup of bacteria with a gene that provides a level of drug resistance that is extremely difficult to treat primarily drove the increase. The rate of those cases jumped more than 460% in recent years in 29 states. Once considered exotic, these bacteria are now more common in the U.S.
