E. coli normally lives in the intestinal tract, but certain activities, such as wiping from the back to the front after a bowel movement, may introduce the bacteria to the urethra, as stated by UCSF Medical Center. Sexual intercourse can also increase a woman's chance of becoming infected, as confirmed by Mayo Clinic. To diagnose an E. coli urinary tract infection, doctors may analyze a urine sample, grow a bacterial culture from urine in a lab, use imaging tests to view the urinary tract, or perform a cystoscopy to see inside of the bladder.

Symptoms of a urinary tract infection may include pain during urination, the frequent need to urinate, lower abdominal pain and abnormally colored urine, as confirmed by UCSF Medical Center. Patients are normally prescribed a seven-day antibiotic course for the E. coli infection, but more severe cases may require a 10- or 14-day course. Patients may also receive pyridium to relieve bladder pain until the antibiotics can clear the infection.
