Question

Quizplus · Accepted Answer

The enterotoxigenic Escherichia coli heat-labile toxin activates second messenger pathways, particularly the adenylate cyclase-cyclic AMP pathway, leading to increased fluid secretion in the intestine and causing secretory diarrhea. It does not damage membranes, increase protein synthesis, activate immune response, or act as a capsule.
