Abstract:
:Enteropathogenic E. coli (EPEC) infection of Hep-2 cells proceeds through bacterial attachment to cell surface and internalization of adhered bacteria. EPEC attachment is a prerequisite for cell infection and is mediated by adhesins that recognize carbohydrate-containing receptors on cell membrane. Such endocytosis-inducer adhesins (EIA) also promote EPEC binding to infant enterocytes, suggesting that EIA may have an important role on EPEC gastroenteritis.
