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]
Though it is harmless while in the gut, ingesting certain types of E. coli — such as E. coli O157:H7 — can cause severe gastrointestinal issues, according to the Mayo Clinic. One way E. coli ...
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.
Also, the doctor might perform a rectal or abdominal examination to exclude the possibilities of inflammatory bowel disease (e.g., Crohn's disease) and pelvic abscesses (pockets of pus). A stool culture (a laboratory test to identify bacteria and other organisms from a sample of feces) can be used to determine the specific virus or germ that is ...
Referred to as E. coli O157:H7 or Shiga toxin-producing E. coli (STEC), this strain of E. coli can be particularly dangerous and even life-threatening. The primary sources of STEC outbreaks are ...
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 ...
An E. coli outbreak linked to McDonald's Quarter Pounders sold at locations across the United States has sickened at least 104 people, landed 34 in the hospital and caused one death. Cases have ...
E. coli is a gram-negative, facultative anaerobe, nonsporulating coliform bacterium. [18] Cells are typically rod-shaped, and are about 2.0 μm long and 0.25–1.0 μm in diameter, with a cell volume of 0.6–0.7 μm 3. [19] [20] [21] E. coli stains gram-negative because its cell wall is composed of a thin peptidoglycan layer and an outer membrane.
