After the bacteria is ingested, enteropathogenic E. coli (EPEC) attaches to the mucosal cells of the small intestine which results in malabsorption and diarrhea. Symptoms such as watery diarrhea, vomiting, non-bloody stools could appear which may last for 1-3 days. What are the two important virulent factors of pathogenesis?

The chromosomal locus of enterocyte effacement (LEE)

The bundle-forming pilus encoded by a plasmid adherence factor (EAF)
