Escherichia coli O157:H7 is a serotype of the bacterial species Escherichia coli and is one of the Shiga-like toxin–producing types of E. coli.It is a cause of disease, typically foodborne illness, through consumption of contaminated and raw food, including raw milk and undercooked ground beef.
Serotype O157:H7 may trigger an infectious dose with 100 bacterial cells or fewer; other strain such as 104:H4 has also caused an outbreak in Germany 2011. Infections are most common in warmer months and in children under five years of age and are usually acquired from uncooked beef and unpasteurized milk and juice.
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 ...
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 ...
However, on January 2, 2007, the United States FDA gave Omnilytics approval to apply its E. coli O157:H7 killing phage in a mist, spray or wash on live animals that will be slaughtered for human consumption. [59] The enterobacteria phage T4, a highly studied phage, targets E. coli for infection. [citation needed]
The E. coli O157:H7 strain that has caused the death of one person is said to cause "very serious disease", especially for the elderly, children and people who are immunocompromised.
Shiga-like toxin (SLT) is a historical term for similar or identical toxins produced by Escherichia coli. [3] The most common sources for Shiga toxin are the bacteria S. dysenteriae and some serotypes of Escherichia coli (shigatoxigenic or STEC), which include serotypes O157:H7, and O104:H4. [4] [5]
The strain involved, E. coli O157:H7, can cause serious illness and was the source of a 1993 outbreak that killed four children who ate undercooked hamburgers at Jack in the Box restaurants.
