Causes of Urinary Tract Infections in Adults
Bacteria that can also live in the digestive tract usually cause a urinary tract infection. Most cases of UTI are caused by a type of bacteria called Escherichia coli (E. coli), which normally lives in the colon. Other microorganisms, such as Chlamydia and Mycoplasma may also cause infections of the urinary tract.
In many cases, bacteria first travel to the urethra—the tube that carries urine from the bladder to outside the body. The bacteria can travel from the urethra to the bladder and kidneys where they multiply and cause infection.
Normally, the body removes the bacteria. However, some people—including women and older people of both sexes—seem to be prone to infection.
