en·ter·o·hem·or·rhag·ic Esch·e·rich·i·a co·li (EHEC),

enterohemorrhagic strains of Escherichia coli, commonly of the serotype 0157:H7; produces a toxin resembling that produced by Shigella; associated with damage to the epithelium, ischemia of the bowel, and necrosis of the colon. Apparently responsible for a hemorrhagic form of colitis without fever, which can be very severe; spread primarily by contaminated beef and poultry. May also cause microangiopathic hemolytic anemia, renal failure, and the hemolytic uremic syndrome.

enterohemorrhagic Escherichia coli

EHEC Any of the E coli serotypes–eg O29, O39, O145 that produces shiga-like toxins, causing bloody inflammatory diarrhea, evoking a HUS. See Escherichia coli O157:H7, Hemolytic uremic syndrome.
