约在半个世纪以前,就已经在人的胃粘膜上发现螺旋状细菌附着。随着胃粘膜活检标本培养此类细菌方法的建立,最近又重新激起了对这些螺旋状细菌的兴趣。这些“弯曲菌样微生物”最近已被正式命名为幽门弯曲菌(Campylobacter Pyloridis,简称CP)。约有半数行上胃肠道内镜检查的病人可培养出 CP,胃的 CP 感染与胃溃疡、十二指肠溃疡、非溃疡性消化不良(ND)和胃炎有关。但是,在大多数这些情况中,CP 的病因学作用尚不清楚。CP 与胃炎 About half a century ago, helical bacteria had been found attached to the human gastric mucosa. With the establishment of gastric mucosal biopsy specimens for culturing such bacteria, interest in these helical bacteria has recently been revived. These “Campylobacter species” have recently been officially named Campylobacter Pyloridis (CP). About half of patients on the gastrointestinal endoscopy can develop CP, which is associated with gastric ulcer, duodenal ulcer, non-ulcer dyspepsia (ND), and gastritis. However, the etiological role of CP is not clear in most of these cases. CP and gastritis
