Includes
Routine stool culture consists of looking for Salmonella, Shigella, Campylobacter sp, and E. coli 0157 and Shiga Toxin 1 and 2 immunoassay. If physician is looking for other stool pathogens (eg, Vibrio, Yersinia, etc), the information must be indicated on the order

Methodology
Bacterial Culture, Aerobic Isolation and Identification Procedures and Enzyme Immuno Assay.
Setup Schedule
Daily
Report Available
2 Days (longer if workup is ongoing)
Reference Range
Normal Value is:
No Salmonella, Shigella, Campylobacter or E. Coli O157 isolated AND
Shiga toxin 1 and Shiga toxin 2 not detected by immunoassay
No Salmonella, Shigella, Campylobacter or E. Coli O157 isolated AND
Shiga toxin 1 and Shiga toxin 2 not detected by immunoassay
Clinical Significance
Salmonella, Shigella, and Campylobacter are considered pathogens when isolated from clinical specimens.
Identification of these organisms is important for treatment and infection control. The Shiga toxin assay
detects toxins produced by enterohemorrhagic E. coli and other enteric organisms which have been isolated from
patients who have hemorrhagic colitis with or without hemolytic-uremic syndrome (HUS).
