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.
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]
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.
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 most common cause of traveler's diarrhea.
The strain involved, E. coli O157:H7, can cause serious illness and was the source of a 1993 outbreak that killed four chil ... Onions have been linked to prior E. coli O157:H7 outbreaks, he said.
On January 12, 1993, Phil Tarr, then a pediatric gastroenterologist at the University of Washington and Seattle's Children's Hospital, filed a report with the Washington State Department of Health (DOH) about a perceived cluster of children with bloody diarrhea and Hemolytic Uremic Syndrome (HUS) likely caused by E. coli O157:H7. [15]
The U.S. Centers for Disease Control and Prevention recommend that "all stools submitted for routine testing from patients with acute community-acquired diarrhea (regardless of patient age, season of the year, or presence or absence of blood in the stool) be simultaneously cultured for E. coli O157:H7 (O157 STEC) and tested with an assay that ...
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 ...
