Product Summary and Explanation
There are four recognized classes of enterovirulent E. coli that cause gastroenteritis in humans. Enterohemorrhagic (EHEC) strain designated E. coli O157:H7, makes up one of the four classes. E. coli serotype O157:H7 is a rare variety of E. coli that produces large quantities of one or more related, potent toxins that cause severe damage to the lining of the intestine. E. coli O157:H7 infection often cause severe bloody diarrhea and abdominal cramps. The infection can also cause a complication called Hemolytic Uremic Syndrome (HUS). The toxins destroy red blood cells and can lead to kidney failure. About 2 – 7% of infections lead to HUS, particularly in children below the age of 5 and the elderly.
The first major outbreak of E. coli O157:H7 was in 1982, and traced to contaminated hamburgers.2 Other known sources of infection include sprouts, lettuce, salami, unpasteurized milk, juice and/or swimming in or drinking contaminated water.
Tryptic Soy Broth, Modified with Novobiocin is used to enrich food samples suspected of having low levels of EHEC during pathogen testing.
