SC131: Anatomy and Phys IIUnit 6: DisscussionHello Professor and Fellow Classmates,UTIs are caused by bacteria normally found in the gastrointestinal tract, such as E. coli. There are other types of bacteria that can cause urinary tract infections such as, staphylococcus, proteus, klebsiella, enterococcus, and pseudomonas. UTIs are mst common in women because the tube running from the bladder to the urethra is much shorter than in men. Because the urethral opening is relatively close to the anus in women, bacteria from stool can easily contaminate the female urethra. A urinary tract infection in young women could also be associated with sexual activity. Most urinary tract infections in men are caused by bacteria. UTIs in older men are more often related to prostate. This can make them more difficult to treat. Having an enlarged prostate, which is common in older men, can limit the body's ability to pass urine.
