Enteroaggregative Escherichia coli (EAEC or EAggEC) are a pathotype of Escherichia coli which cause acute and chronic diarrhea in both the developed and developing world. [1] [2] They may also cause urinary tract infections. [2] EAEC are defined by their "stacked-brick" pattern of adhesion to the human laryngeal epithelial cell line HEp-2. [3]
Enterotoxigenic Escherichia coli (ETEC) is a type of Escherichia coli and one of the leading bacterial causes of diarrhea in the developing world, [1] as well as the most common cause of travelers' diarrhea. [2] Insufficient data exists, but conservative estimates suggest that each year, about 157,000 deaths occur, mostly in children, from ETEC.
Enteroinvasive E. coli (EIEC) invades (passes into) the intestinal wall to produce severe diarrhea. Enterohemorrhagic E. coli (EHEC): A type of EHEC, E. coli O157:H7, can cause bloody diarrhea and hemolytic uremic syndrome (anemia and kidney failure). Enterotoxigenic E. coli (ETEC) produces a toxin that acts on the intestinal lining, and is the ...
E. coli bacteria often carry multiple drug resistance plasmids, and under stress, readily transfer those plasmids to other species. Mixing of species in the intestines allows E. coli to accept and transfer plasmids from and to other bacteria. Thus, E. coli and the other enterobacteria are important reservoirs of transferable antibiotic ...
It does not belong to the fecal coliforms (or thermotolerant coliforms) group of bacteria, unlike Escherichia coli, because it is incapable of growth at 44.5 °C in the presence of bile salts. [citation needed] Some of them show quorum sensing properties. [2] [3] One clinically important species from this genus is E. cloacae.
The normal small bowel has less than 10 4 bacteria per millilitre. [citation needed] Some experts however, consider aspiration of more than 10 3 positive if the flora is predominately colonic type bacteria as these types of bacteria are considered pathological in excessive numbers in the small intestine. The reliability of aspiration in the ...
Entamoeba coli is a non-pathogenic species of Entamoeba that frequently exists as a commensal parasite in the human gastrointestinal tract. E. coli (not to be confused with the bacterium Escherichia coli) is important in medicine because it can be confused during microscopic examination of stained stool specimens with the pathogenic Entamoeba histolytica.

Enterocolitis is an inflammation of the digestive tract, involving enteritis of the small intestine and colitis of the colon. [1] It may be caused by various infections, with bacteria, viruses, fungi, parasites, or other causes.
