Treatments For Urinary infections Leave Bacteria Bald, Happy And Vulnerable

A different approach to treating urinary tract infections (UTIs) could defeat the bacteria that cause the infections without directly killing them, a strategy that could help slow the growth of antibiotic-resistant infections. Instead of trying to wipe out bacteria, researchers in the laboratory of Scott Hultgren, Ph.D., the Helen L. Stoever Professor of Molecular Microbiology at Washington University School of Medicine in St. Louis, have been working to create pharmaceuticals that essentially "defang" the bacteria by preventing them from assembling pili, microscopic hairs that both enable the invasion of host cells and allow the bacteria to mount a cooperative defense against the host's immune system.
