For diagnosis of common causes of bacterial gastroenteritis. This test routinely detects Salmonella, Shigella, Campylobacter, Yersinia enterocolitica, Escherichia coli O157:H7. It also includes a Shiga toxin test to detect other Shiga-toxin-producing E. coli strains. If other pathogens (such as Aeromonas, Vibrio) are suspected based upon patient history, communicate with lab so additional steps can be taken to maximize chance of recovery.
Patient Preparation
If possible, avoid recent antibiotics, x-ray contrast material, antidiarrheal medications, antacids, bismuth, and mineral oil.

Unacceptable Conditions
Specimens are not acceptable for routine culture if the patient has been admitted to the hospital for more than 3 days because bacterial gastroenteritis is an acute community-acquired disease and generally does not develop after hospitalization. In rare instances specimens may be acceptable after this three-day time period, but specific approval must be obtained from the microbiology laboratory director before being submitted.
Specimens from bedpans are acceptable unless there is residual soap, detergent, disinfectant, or urine.
Diapers are not acceptable.
