Medical Term:

enterotoxigenic Escherichia coli


Definition: strain of Escherichia coli that attaches to the duodenum or proximal small intestine mucosa, where it forms heat-stable and heat-labile toxins that activate adenylate cyclase, causing watery diarrhea. Responsible for 40–70% of traveler's diarrhea; chiefly waterborne in human feces. Most important cause of diarrhea among infants living in tropics.
