In brief: Shiga toxin E. coli

Infections are diagnosed by finding sorbitol non-fermenting e.
Coli in the stool (for o157:h7) and better by radioimmunoassays for shiga toxin in the stool of a patient with nonfebrile, bloody diarrhea.

In brief: Routine

All stool samples from patients with severe diarrhea sent to the microbiology lab are plated on media selective for shiga-toxin producing e.
Coli, and may be subjected to an enzyme immunoassay when received. Positives go to public health labs that do pulsed-field gel electrophoresis and gene studies for comfirmation.
