A stool culture is used to detect the presence of disease-causing bacteria (pathogenic) and help diagnose an infection of the digestive tract. It is often used along with other tests such as an O&P test that detects parasites in the stool and/or Clostridium difficile and C. difficile toxin tests, to help determine the cause of prolonged diarrhea. In establishing the cause, the test can help guide treatment, determining whether antibiotics or other medication may be necessary to resolve symptoms. The York Hospital Laboratory evaluates stool cultures for the most common intestinal pathogens:      Campylobacter species      Salmonella species      Shigella species      Escherichia coli (E. coli) O157:H7 This culture also identifies Yersinia species if present.
