Although most Escherichia coli are harmless commensals of the human intestine, certain specific, highly-adapted E. coli strains are capable of causing urinary tract, systemic or enteric/diarrheagenic infection. Diarrheagenic E coli are divided into six distinct categories, or pathotypes, each with a distinct pathogenic scheme (Table 1). Combined, diarrheagenic E coli have emerged as perhaps the most important enteric pathogens of man. In the developing world, the E coli categories account for more cases of gastroenteiltis among infants than any other cause (1) In addition, E coli are also the most common cause of traveller's diarrhea, which afflicts more than one million travellers to the developing world annually (1). Enterohemorrhagic E coli (EHEC) are the cause of hemolytic uremic syndrome (HUS), which has become a major foodborne threat in many parts of the developed world (2).
