Why do some people get UTIs over and over? A new report holds clues

View Content

Research from a team at Washington University School of Medicine including Tom Hannan, DVM, PhD, Instructor of Pathology & Immunology, offers insight into why some people get repeat urinary tract infections (UTIs). The team’s findings, which were published recently in Nature Microbiology, suggest that UTIs can actually change the DNA in the cells lining the urinary tract. Those cells can then change size and start an immune response that actually makes them more susceptible to repeated infections.
