Diarrhea remains one of the main causes of morbidity and mortality worldwide, and E. coli O157:H7 is a major cause of diarrheal disease in the U.S.A. Fecally contaminated food and water are the sources of E. coli O157:H7 infections in humans. Cattle and other ruminants have been established as natural reservoirs for E. coli O157:H7, and these food production animals play a significant role in the epidemiology of human infections. The overall goal of this work is the development of an assay for the rapid detection of Escherichia coli O157:H7 in food production animals, as a preliminary step to decrease contamination of meat with E. coli O157:H7.
