Shiga toxin-producing E. coli(STEC), also called verotoxinogenic E. coli, usually do not cause disease inanimals but may cause watery diarrhoea, haemorrhagic colitis, and/orhaemolytic uraemic syndrome in humans. Zoonotic STEC include the O157:H7strains and, with increasing frequency, certain non-O157 strains.
(5) The Enterohemorrhagic E. coli (EHEC) group includes the infamous O157:H7 serogroup. Strains in the EHEC group produce enterotoxins (verotoxins) that cause severe bloody diarrhea (hemorrhagic colitis) and hemolytic uremic syndrome (HUS) in humans. (5) E. coli is also a major cause of urinary tract infections and nosocomial infections including septicemia and meningitis.
