What are the causes of a urinary tract infection (UTI)?

ANSWER

Most urinary tract infections are caused by bacteria normally found in your gut, such as E. coli. Other bacteria that can cause them include staphylococcus, proteus, klebsiella, enterococcus, and pseudomonas.

Some bladder infections in both men and women are linked to two sexually transmitted bugs -- chlamydia trachomatis and mycoplasma. Another parasite, trichomonas, can cause similar symptoms.
