Prominent types of E. coli pathogens based on varying mechanisms of infection. There are five types of diarrhoeagenic strains that pertain specifically to the alimentary tract: enteropathogenic (EPEC), enterohaemorrhagic (EHEC), enterotoxic (ETEC), enteroinvasive (EIEC), and enteroaggregative (EAEC). Uropathogenic E. coli (UPEC) strains have the ability to escape through the circulatory system and infect cells in the urinary tract, thereby causing urinary tract infections
