幽门螺杆菌 Helicobacter pylori

(重定向自H. Pylori)
幽门螺杆菌对胃黏膜造成的伤害① 胃内幽门螺杆菌的鞭毛在胃粘液层内部移动、并附著于上皮细胞的表面。 ② 尿素酶遇上黏液中的尿素而产生氨,中和了胃酸。 ③ 没被胃酸杀死的幽门螺杆菌在黏液层进行增殖。此外,趋化因子将周围的其他幽门螺杆菌引来。 ④ 幽门螺杆菌产生的各种分解酵素破坏了黏液层,让失去黏膜保护的上皮细胞发炎(参考图中央)。此外细菌分泌出的VacA等毒素(右)、透过IV型分泌装置注入上皮细胞的反应器(effector)分子(左)对上皮细胞产生伤害,让发炎的症状恶化。

幽门螺杆菌幽门螺旋杆菌幽门螺旋菌(学名:Helicobacter pylori发音为/ˌhɛlɪkɵˈbæktər pɪˈlɔəraɪ/)是革兰氏阴性、微需氧的细菌,生存于胃部及十二指肠的各区域内。它会引起胃黏膜轻微的慢性发炎,甚或导致胃及十二指肠溃疡与胃癌。超过80%的带原者并不会表露病征。

幽门螺杆菌最初被命名为幽门弯曲菌(Campylobacter pyloridis),后为修正拉丁语语法错误而变为C. pylori。****年,16S rRNA基因定序等研究显示其并不属于弯曲菌属,幽门螺杆菌便被独立归类至螺杆菌属。螺杆菌属(Helicobacter)源自古希腊的词汇「hělix/έλιξ」(意为螺旋或缠绕)。属名加词「pylōri」则是指「幽门的」或幽门阀(从胃部通往十二指肠的圆状开口),源自古希腊词汇「πυλωρός」,意为守门人。 一旦家庭中成年人被发现有「胃幽门螺旋杆菌」的感染时,共同生活的孩童亦会有相同的感染现象。

Helicobacter pylori 幽门螺杆菌

Helicobacter pylori, previously Campylobacter pylori, is a gram-negative, microaerophilic bacterium found usually in the stomach. It was identified in 1982 by Australian scientists Barry Marshall and Robin Warren, who found that it was present in a person with chronic gastritis and gastric ulcers, conditions not previously believed to have a microbial cause. It is also linked to the development of duodenal ulcers and stomach cancer. However, over 80% of individuals infected with the bacterium are asymptomatic, and it may play an important role in the natural stomach ecology.
