早在十九世纪末就有在狗、猫、棕色的挪威鼠胃中发现螺形菌的报道。1983年Marshall从人胃中分离到幽门弯曲菌(Cp)。1989年Goodwin经研究后认为Cp不同于弯曲菌属细菌。提出了一个新属名螺杆菌(H),并确定Cp是这一菌中的代表菌种,称作幽门螺杆菌(H.pylori,Hp)。H属最主要的特征是指这一类细菌属革兰氏阴性,螺旋形,有带鞘的鞭毛,微需氧,尿素酶(+),有特殊的脂肪酸组成等。 近年的研究探明幽门螺杆菌(Hp)感染是十二指肠溃疡、胃溃疡、慢性胃炎、十二指肠炎、巨大粘膜皱 As early as the end of the nineteenth century, there were reports of spirulina bacteria found in dogs, cats, and brown Norwegian rat stomachs. In 1983, Marshall isolated Campylobacter pylori (Cp) from human stomach. 1989 Goodwin after the study that Cp is different from Campylobacter bacteria. A new genus Helicobacter (H) was proposed and identified as the representative species in this bacterium, called H. pylori (Hp). H is the most important feature of this class of bacteria are Gram-negative, spiral, serrated flagella, micro-aerobic, urease (+), with special fatty acid composition. Recent studies have identified Helicobacter pylori (Hp) infection is duodenal ulcer, gastric ulcer, chronic gastritis, duodenitis, huge mucosal folds
