E.coli 0157:H7 Culture
Salmonella Culture
Shigella Culture
Yersinia Culture
Laboratory: Microbiology (VH)
Specimen Type: Stool
Colostomy or Ileostomy contents
Collection Information: This sample type cannot be processed as a STAT request. Samples are handled in a priority sequence and results are reported as they become available.

Avoid the use of mineral oil, compounds containing Kaolin or barium, bismuth, Milk of Magnesia, antacids, prior to collection.

Avoid contamination with urine.

Have patient pass stool onto a clean, dry bedpan. Transfer a portion of stool containing mucous, blood or pus to enteric transport media.

Rectal swabs are inferior specimens for isolation of enteric pathogens.

If Aeromonas, Plesiomonas, Vibrio, Campylobacter other than C.jejuni/coli., Enteropathogenic E.coli other than 0157 are suspected, indicate this on the request.

If patients in the Neonatal Unit are suspected of Necrotizing Syndrome or colonization indicate this on the request.

If food or waterborne outbreaks are suspected, indicate this on the request.

For Clostridioides (Clostridium) difficile toxin, see separate listing in Lab Test Information Guide.
Comments: 1. Adults:
The Lab routinely screens for Campylobacter jejuni/coli, E.coli 0157:H7, Salmonella and Shigella.
Note: if Yersinia is suspected, please indicate when ordering.

2. Children:
The Lab routinely screens for Campylobacter jejuni/coli, E.coli 0157:H7, Salmonella, Shigella and Yersinia.

If other pathogens are suspected due to patient history or travel etc., please discuss with a Microbiologist and notify the laboratory in advance.

Inpatients (in hospital 72 hours or more) whose admitting diagnosis is not gastroenteritis or diarrhea will be processed for C. difficile toxin only( see separate listing in Lab Test Information Guide ).

Outpatients or patients admitted with gastroenteritis or diarrhea will be screened for Campylobacter jejuni/coli, E.coli 0157:H7, Salmonella, Shigella and Yersinia.

Infection Control Practitioners and physicians are notified of significant isolates.
