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 ...
Pathogenic E. coli strains can be categorized based on elements that can elicit an immune response in animals, namely: [citation needed] O antigen: part of lipopolysaccharide layer; K antigen: capsule; H antigen: flagellin; For example, E. coli strain EDL933 is of the O157:H7 group.
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.
Most strains of E. coli are harmless; however, if the bacterium gets into the bloodstream due to a weakened immune system it can cause infections, ranging from mild to life-threatening.
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; Escherichia coli K1, meningitis; Adherent Invasive Escherichia coli (AIEC), morbus Crohn ...
Different strains of E. coli are often host-specific, making it possible to determine the source of fecal contamination in environmental samples. [13] [14] For example, knowing which E. coli strains are present in a water sample allows researchers to make assumptions about whether the contamination originated from a human, another mammal, or a ...
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 ...
One way E. coli is spread is when feces contaminate food and water. Since animals can potentially carry pathogenic E. coli, touching animals, such as at a petting zoo, can potentially put you at risk.
