ABSTRACT
Entrohemorrhagic Escherichia coli O157:H7 is a major food borne pathogen causing severe disease in humans worldwide. Healthy cattle
are the reservoir of Escherichia coli O157:H7, and bovine food products and fresh produce contaminated with bovine waste are the most common source for disease out breaks in the United States. Escherichia coli O157:H7 also survives well in the environment. The abilities to cause human disease, colonize the bovine gastrointestinal tract, and require that Escherichia coli O157:H7 adapt to a wide variety of conditions. Three major virulence of factors of Escherichia coli O157:H7 have been identified including shiga toxins, products of the pathogenicity island called the locus of enterocyte effacement, and product of he F-like plasmid PO157. Among these virulence factors, the role of PO157 is least understood.
