watery
Enterotoxigenic E coli (ETEC) strains produce LT and/or ST enterotoxins in the large intestine.
False
Enteropathogenic E coli (EPEC) attaches to small intestine enterocytes using bundle-forming pili (BFP) and an injection (type iii) secretion system.
True
The reservoir for Enteropathogenic E coli (EPEC) is primarily adult carriers, and transmission occurs through contaminated food and water.
False
Test your knowledge of E coli intestinal infections and their classification based on virulence properties such as enterotoxigenic, enteropathogenic, enteroinvasive, enterohemorrhagic, and enteroaggregative. Explore the different mechanisms by which each group causes disease.
