Not all types of E. coli bacteria make people sick, but a certain type of E. coli, called Shiga toxin-producing E. coli or “STEC” for short, make a toxin (poison) that can make some people very sick.

E. coli are a diverse group of bacteria that normally live in the intestines of humans and animals. Although most strains of these bacteria are harmless, some produce toxins that can make you sick and cause diarrhea (loose stool/poop) such as Shiga toxin-producing E. coli (STEC).

Shiga toxin-producing E. coli (STEC) is most likely to cause severe illness. Most people associate E. coli with digestive symptoms. Outbreaks sometimes cause severe illness, including bloody diarrhea. What is E. coli?

Some kinds of E. coli cause symptoms by making a toxin (a poisonous substance that is a specific product of the metabolic activities of a living organism) called Shiga toxin. The bacteria that make these toxins are called “Shiga toxin-producing” E. coli, or STEC for short.

2024年5月14日 · E. coli infection can be serious. Infection with Shiga toxin-producing E. coli (STEC) can lead to a serious health condition called hemolytic uremic syndrome (HUS). HUS can lead to kidney failure, permanent health problems, and even death.

In 1977, researchers in Ottawa, Ontario discovered the Shiga toxin normally produced by Shigella dysenteriae in a line of E. coli. [12] The E. coli version of the toxin was named "verotoxin" because of its ability to kill Vero cells (African green monkey kidney cells) in culture.

2024年9月6日 · Escherichia coli that contain genes encoding Shiga toxins 1 and/or 2 are important human pathogens; these are referred to as Shiga toxin-producing Escherichia coli (STEC). Some strains, such as E. coli O157:H7, cause severe disease including painful bloody diarrhea, as well as hemolytic uremic syndrome (HUS) in some cases.

Escherichia coli that contain genes encoding Shiga toxins 1 and/or 2 are important human pathogens; these are referred to as Shiga toxin-producing Escherichia coli (STEC). Some strains cause severe disease including painful bloody diarrhea, as well as hemolytic uremic syndrome (HUS) in some cases.

Shigatoxigenic Escherichia coli (STEC) and verotoxigenic E. coli (VTEC) are strains of the bacterium Escherichia coli that produce Shiga toxin (or verotoxin).

2011年6月7日 · Multiple teams of scientists are looking into how E. coli causes disease, including enterohemmaorrhagic Shiga toxin-producing E. coli (known to scientists as EHEC/STEC). EHEC/STEC causes severe disease and sometimes death.
