Urinary tract infections (UTIS) include infections of the urethra, the bladder, or the kidneys. In hospitals, UTIs are more common in patients whose urinary catheters remain inserted long enough for bacteria to travel up the catheter. Outside medical facilities, UTIS generally result when bacteria that are normally found in other parts of the body move into the urinary tract-so-called opportunistic infections. Most of these infections occur when microbes from the large intestine accidentally enter the urethra, which happens more often in women than in men because female urethras are shorter and closer to the anus than are men's. - Urethral and bladder infections can escalate into kidney infections, which can be fatal. Proper treatment of UTIs may require first identifying which microbes are causing the infection. Imagine you are a hospital laboratory technician charged with identifying the microbe(s)causing a patient's UTI. 1. How would you go about narrowing down the list of potential bacterial culprits? 2. How would you distinguish organisms causing the infection from the harmless normal microbiota of the body.
