Mechanisms of gut damage by Escherichia coli.
This chapter primarily concerns three main categories of diarrhoeagenic Escherichia coli, enteropathogenic (EPEC), enterohaemorrhagic (EHEC) and enteroaggregative (EAEC) E. coli. They have distinctive virulence factors and vary in the enteropathies they produce. The molecular biological approach has opened up the complex way in which they interact with the intestine. EPEC and EHEC show a subversive approach to colonization in that they adapt the host cell to their requirements in the formation of the attaching effacing lesion. EAEC appear to co-opt the host defence system to produce a biofilm-like colony and currently go unrecognized in routine laboratories.
