Rise of “Nightmare Bacteria”: A Growing Concern in the US
In a disturbing trend, infection rates from drug-resistant “nightmare bacteria” have skyrocketed by almost 70% between 2019 and 2023, according to a recent report from the Centers for Disease Control and Prevention (CDC) scientists. The primary driver of this increase is the emergence of bacteria carrying the NDM gene, which renders them highly resistant to treatment. Only two antibiotics are effective against these infections, and they are expensive and require intravenous administration.
The NDM gene was once considered a rare and exotic phenomenon, primarily associated with patients who had received medical care overseas. However, the rate of US cases has jumped more than fivefold in recent years, with 4,341 cases of carbapenem-resistant bacterial infections reported in 29 states in 2023. Of these, 1,831 were attributed to the NDM variety. The CDC researchers warn that the actual number of cases may be higher due to incomplete testing and reporting.
Expert Insights and Concerns
David Weiss, an Emory University infectious diseases researcher, describes the rise of NDMs in the US as a “grave danger and very worrisome.” The CDC scientists also express concern that many people may be unrecognized carriers of the drug-resistant bacteria, which could lead to community spread. Dr. Maroya Walters, one of the report’s authors, notes that this may result in infections like urinary tract infections becoming chronic problems, rather than routine and easily treatable conditions.
The misuse of antibiotics is a significant contributing factor to the rise of antimicrobial resistance. Unfinished or unnecessary prescriptions can create an environment where germs like bacteria and fungi can develop resistance to the drugs designed to kill them. The CDC has been drawing attention to the issue of “nightmare bacteria” resistant to a wide range of antibiotics, including carbapenems, which are considered a last resort for treating serious infections.
Implications and Future Directions
Researchers believe that the COVID-19 pandemic may have played a role in the increase in antibiotic resistance, with a surge in antibiotic use during this period likely contributing to the rise in drug-resistant cases. Dr. Jason Burnham, a Washington University researcher, notes that the CDC’s count is only a partial picture, as many states are not fully testing and reporting cases. The actual number of US infections is likely underestimated, particularly in populous states like California, Florida, New York, and Texas, which were not included in the CDC’s data.
This report is not the first to highlight the growing concern of NDM cases. A previous CDC report published in June noted an increase in NDM cases in New York City between 2019 and 2024. As the situation continues to evolve, it is essential to stay informed and take proactive steps to address the issue of antimicrobial resistance. For more information, visit Here
