This test detects Shiga 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). Culture allows CDC to track outbreaks by strain typing.
Collect in clean, dry container and then transfer a minimum of 1 gram
or 1 mL into a Cary-Blair stool culture transport medium. Fluid level
should reach line on vial.
Frozen (-70 deg C) specimens are sub-optimal but can be tested
directly without broth enhancement or reflex culture.
