Enterohemorajik Escherichia coli (EHEC)

Escherichia coli insan ve sıcak kanlı hayvanların gastrointestinal sistem florasında bulunan bir bakteridir. E. coli türlerinin çoğu insanlar için zararsızdır. E. coli O157:H7 enterohaemorajik, verositoksin veya şigatoksin üreten tür olarak bilinir ve patojenik E.coli grubu içinde en yaygın olanıdır. EHEC bakterisi hemorajik kolit ve hemolitik üremik sendromun en önemli nedenidir. Bakterinin kaynağı sığır ve deve gibi geviş getiren hayvanlardır. Bakteri insanlara ana olarak kontamine olmuş gıdaların tüketimi yoluyla bulaşmaktadır.

Enterohemorrhagic Escherichia coli (EHEC)]

Escherichia coli is a bacterium that is commonly found in the gut of humans and warm-blooded animals. Most strains of E. coli are harmless for human. E. coli O157:H7 is the most common member of a group of pathogenic E. coli strains known variously as enterohaemorrhagic, verocytotoxin-producing, or Shiga-toxin-producing organisms. EHEC bacterium is the major cause of haemorrhagic colitis and haemolytic uraemic syndrome. The reservoir of this pathogen appears to be mainly cattle and other ruminants such as camels. It is transmitted to humans primarily through consumption of contaminated foods.
