Enterohemorrhagic Escherichia coli (EHEC) serotype O157:H7 is the most important recently emerged group of food-borne pathogens. It can cause severe gastrointestinal disease, including fatal infections, and is being detected more frequently world-wide. More investigations regarding the laboratory diagnosis of these organisms have been carried out in recent years than with any other group of food-borne pathogens, yet this group remains the most difficult to detect. Research on food born bacterial pathogen started in our lab. on Oct.,11th, 1991 on E. coli O157:H7 in the form of a channel system in cooperation with Prof. Dr. Larry R. Beuchat of the Univ. of Georgia, College of agriculture, Georgia Agric. Exp. Station, Dept. of Food Science and technology, Georgia Station, Griffin, Georgia, 30223, USA. Here I try to search for E. coli O157:H7 in Egyptian food. Here I try to search for E. coli O157:H7 in Egyptian food.
