6.肠出血性大肠杆菌(EHEC) 这也被称为产志贺毒素大肠杆菌(STEC)。它会产生一种名为志贺毒素的毒素,使您生病。这种毒素会损害您的肠道内壁。它通常存在于肉(加工过程中受到污染且未充分煮熟)、未经高温消毒的牛奶以及使用含有 EHEC/STEC 的粪肥施肥的蔬菜中。 一种特别严重的肠出血性大肠杆菌菌株,称为 O157:H7,...
Sensing environmental signals to site-specifically express the type-III secretion system (T3SS), which injects effectors into host cells leading to intestinal colonization and disease, is key to the pathogenesis of EHEC. Here, we reveal that EHEC O157:H7, a dominant EHEC serotype frequently ...
以下是几种常见的Escherichiacoli致病菌株: 1.肠毒素产生菌株(EnterotoxigenicE.coli,简称ETEC):ETEC菌株是引起旅行者腹泻的主要病因之一,通过产生肠毒素引发腹泻症状。 2.肠出血性大肠杆菌(EnterohemorrhagicE.coli,简称EHEC):EHEC菌株是引起食物污染相关疾病的常见病原体之一,其中O157:H7菌株引起的疾病最为严重,可导致...

E.colican cause infections in various systems of the body. It can attach to cells and damage it or it can secrete toxins (enterotoxins) which cause widespread inflammation. Some strains ofE.coli, like enterohemorrhagicE.coli(EHEC), can do both.E.coliare commonly found in the small and lar...
