E. coli bacteria are one of the causes of acute diarrhea. There are different kinds of E.coli bacteria in which some are pathogenic and some are non-pathogenic. Generally most of the bacteria are non-pathogenic and reside in intestine and colon. These non-pathogenic E.coli bacteria do not cause disease in the intestine but if they spread outside the intestine, then they cause infection in various body parts like urinary tract or in the blood stream.

Some of the E.coli bacteria are pathogenic means they can cause infection in the intestine. Diarrhea is generally caused by these pathogenic kinds of E.coli bacteria. They affect intestine or colon by producing toxin called enterotoxigenic E. coli (ETEC) or by inflaming the lining of small intestine and colon, causing enterocolitis called enteropathogenic E. coli (EPEC).

Traveler’s diarrhea is generally caused by pathogenic kinds of E.coli bacteria by producing toxins in small intestine. Poor sanitation facility and by eating contaminated food are the main reason of traveler’s diarrhea. Abdominal cramp, nausea and vomiting are few symptoms of traveler’s diarrhea caused by E.coli bacteria. These symptoms generally occur in 3 to 7 days after you have arrived in some foreign country.
