Enteroaggregative Escherichia coli (EAEC) is a type of strain from E.coli. E.coli causes intestinal infections, some intestinal infections include diarrhea, fever and abdominal pain. Most severe cases can lead to bloody diarrhea, dehydration or even kidney failure.
Escherichia coli O104:H4 is an enteroaggregative Escherichia coli strain of the bacterium Escherichia coli, and the cause of the 2011 Escherichia coli O104:H4 outbreak. [1] The "O" in the serological classification identifies the cell wall lipopolysaccharide antigen, and the "H" identifies the flagella antigen.
Enteroaggregative E. coli (EAEC) found only in humans Watery So named because they have fimbriae which aggregate tissue culture cells, EAEC bind to the intestinal mucosa to cause watery diarrhea without fever. EAEC are noninvasive. They produce a hemolysin and an ST enterotoxin similar to that of ETEC. Enteroinvasive E. coli (EIEC) found only ...
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.
Enteroinvasive E. coli (EIEC) Enterohemorrhagic E. coli (EHEC) Enteroaggregative E. coli (EAEC) Uropathogenic E. coli (UPEC) Verotoxin-producing E. coli; E. coli O157:H7 is an enterohemorrhagic strain also 2006 North American E. coli outbreak; E. coli O104:H4, also 2011 E. coli O104:H4 outbreak; Escherichia coli O121; Escherichia coli O104:H21
The outbreak was caused by a strain of E. coli of the serotype O104:H4, that was unusual for having characteristics of both enteroaggregative E. coli and enterohemorrhagic E. coli. [83] The strain has a number of virulence genes typical of enteroaggregative E. coli, including attA, aggR, aap, aggA, and aggC, in addition to the Shiga toxin ...
Enterotoxigenic E. coli (ETEC) produces a toxin that acts on the intestinal lining, and is the most common cause of traveler's diarrhea. Enteropathogenic E. coli (EPEC) can cause diarrhea outbreaks in newborn nurseries. Enteroaggregative E. coli (EAggEC) can cause acute and chronic (long-lasting) diarrhea in children.
This strain has both enteroaggregative and enterohemorrhagic properties. Both the O145 and O104 strains can cause hemolytic-uremic syndrome (HUS); the former strain shown to account for 2% to 51% of known HUS cases; an estimated 56% of such cases are caused by O145 and 14% by other EHEC strains.
