The diarrhea associated with enteropathogenic Escherichia coli (EPEC) is the result of:

A. Plasmid-mediated A/E histopathology with disruption of normal microvillus structure resulting in malabsorption and diarrhea
B. Plasmid-mediated, heat-stable and/or heat-liable enterotoxins that stimulate hypersecretion of fluids and electrolytes
C. Mediated by cytotoxic Shiga toxins (STx-1, STx-2), which disrupt protein synthesis.
D. Plasmid-mediated invasion and destruction of epithelial cells lining colon


Ans: A. Plasmid-mediated A/E histopathology with disruption of normal microvillus structure resulting in malabsorption and diarrhea
