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