Researchers have discovered that an initial UTI can set the tone for subsequent infections. In mouse studies, the researchers found that a transient infection triggers a short-lived inflammatory response that rapidly eliminates the bacteria. But a lingering infection leads to persistent inflammation and long-lasting changes to the bladder that prime the immune system to overreact to bacteria the next time, worsening the infection.
