How Your Chicken Dinner Is Creating a Drug-Resistant Superbug

Adrienne LeBeouf recognized the symptoms when they started. The burning and the urge to head to the bathroom signaled a urinary tract infection, a painful but everyday annoyance that afflicts up to 8 million U.S. women a year. LeBeouf, who is 29 and works as a medical assistant, headed to her doctor, assuming that a quick course of antibiotics would send the UTI on its way.

That was two years ago, and LeBeouf has suffered recurring bouts of cystitis ever since. She is one of a growing number of women, and some men, who have unknowingly become infected with antibiotic-resistant versions of E. coli, the ubiquitous intestinal bacterium that is the usual cause of UTIs.

There is no national registry for drug-resistant infections, and so no one can say for sure how many resistant UTIs there are. But they have become so common that last year the specialty society for infectious-disease physicians had to revise its recommendations for which drugs to prescribe for cystitis -- and many infectious-disease physicians and gynecologists say informally that they see such infections every week.

Dr. Jehan El-Bayoumi, LeBeouf's physician and an associate professor of medicine at George Washington University Medical Center, said she has seen "a really significant increase, especially within the past two to three years."
