Enterohemorrhagic E coli (EHEC) Shiga Toxin, EIA
- E coli O157
- EHEC, Stool Culture
- Shiga Toxin
Detect the presence of Shiga-toxin-producing enterohemorrhagic E coli
There are four types of pathogenic E coli (see table). This test detects only enterohemorrhagic E coli; tests are not available for the other pathogenic E coli.
Travelers' diarrhea and infant diarrhea in less developed countries
Hemolytic uremic syndrome
Thrombotic thrombocytopenia purpura
Detection of enterohemorrhagic E coli Shiga toxins by enzyme immunoassay (EIA)
No enterohemorrhagic E coli Shiga toxin detected
Treatment of patients infected with Enterohemorrhagic E coli (EHEC) with antibiotics is contraindicated. Hemorrhagic colitis can be differentiated from other causes of diarrhea by its progression from watery to bloody diarrhea during a few days' time. Fecal leukocytes are markedly increased. Fever is usually absent. The disease is mediated by the production of a Shiga-like toxin that interferes with colonic brush border cells, protein synthesis, and ultimately causes cell death. Enterohemorrhagic E coli (EHEC) differ from other strains of bacteria in the large amount of toxin they produce. Virtually all O157:H7 organisms and other EHEC strains have been shown to produce Shiga toxin.
