<i>E. coli</i> Invading Bladder (IMAGE) Washington University School of Medicine Caption An E. coli bacterium (above, in gold) attaches to and invades cells lining the inner surface of the bladder. UTIs are among the most common infections, and they tend to recur. Researchers at Washington University School of Medicine in St. Louis have found a molecular decoy that reduces the number of UTI-causing gut bacteria. This compound potentially could lower the chance of repeat UTIs.
