Enteropathogenic Escherichia coli (EPEC) contact secretion system. A type III secretion system apparatus has been inserted into the cell and is exporting secretion proteins (Esps) into the cytoplasm.
The intimin receptor has been inserted below the host cell membrane and is now mediating tight binding to the surface.
The other Esps have disrupted multiple cellular functions, including the structure of the cytoskeleton.
Cytoskeleton elements have been concentrated to form a pedestal cradling the EPEC
