Enterotoxigenic E.coli (ETEC)
Test Code: E65008
This assay is only available as part of a panel and cannot be ordered individually.
Enterotoxigenic Escherichia coli (ETEC) is another diarrhea-causing E. coli that is considered a major cause of traveler’s diarrhea in adults in industrialized countries and a leading cause of infant diarrhea in developing countries.1-3 ETEC is estimated to cause 200 million episodes of diarrhea and approximately 380,000 deaths in children in the developing world and travelers to those areas.4 In the U.S., ETEC is estimated to cause approximately 17,800 foodborne illnesses annually.5 Enterotoxins produced by ETEC strains include heat-labile LT toxin and heat-stable ST toxin.3,6 ETEC illnesses are usually associated with acute watery diarrhea and sometimes nausea, headache, vomiting or fever.7
