A Live-Attenuated Vaccine for Urinary Tract and Other Bacterial Infections NU 2008-004 Inventors Anthony J. Schaeffer* David J. Klumpp Benjamin Billips Abstract Urinary tract infections, either chronic or acute, are a frequent health problem in a variety of populations. Northwestern investigators have demonstrated that deletion of a certain gene from urinary-tract colonizing bacteria has resulted in a strain that promotes immune response when administered to mammalian subjects. The modified bacterium does not establish a persistent population in the bladder, but promotes cytokine secretion from urothelial cells. These bacteria represent a candidate material for a live-attenuated vaccine that could be used to protect against acute and recurrent urinary tract infections. Successful tests have been performed in a mouse model. Applications o Preventative medicine for UTIs o Alternative to repeated use of antibiotics o Particularly useful for nursing home patients or other high-risk groups Advantages o Prevents infection by stimulating patient immune system o Inexpensive, easy-to-grow bacterium o Simple to administer Publications Billips, B.
