Etec --> enterotoxigenic escherichia coli

Enterotoxigenic strain of escherichia coli; attaches to the duodenum or proximal small intestine mucosa, where it forms heat-stable and heat-labile toxins that activate adenylate cyclase, causing wasting diarrhoea. Responsible for 40-70% of travelers diarrhoea; chiefly water-borne via human faeces. Most important cause of diarrhoea among infants living in tropical areas.
