A
Although E. coli is a normal bowel inhabitant, its pathogenic classification is somewhere between that of overt pathogens and opportunistic organisms. Strains of this species, such as ente-rotoxigenic E. coli (ETEC), enteroinvasive E. coli (EIEC), and enteroaggregative E. coli (EAEC), express potent toxins and cause serious gastrointestinal infections. In addition, in the case of en-terohemorrhagic E. coli (EHEC), life-threatening systemic disease can result from infection.
