自从1983年Marshall等分离出幽门螺杆菌(HP)以来,经过国内外学者大量研究证实,HP是一种微需氧的G~-杆菌,其典型形态为S状弯曲。人的胃粘膜是HP的自然定植部位。HP能在酸性胃液中存活。通过特异的粘附素粘附于胃上皮(包括食道和十二指肠的胃上皮化生区)表现出明显的嗜组织特异
Since Helicobacter pylori (HP) was separated by Marshall et al. In 1983, a large number of domestic and foreign scholars have confirmed that HP is a microaerophilic G ~ - bacterium, and its typical morphology is S-shaped. Human gastric mucosa is the natural site of HP colonization. HP can survive in acid gastric juice. Adherence to the gastric epithelium by specific adhesins (gastric epithelial metaplastic regions including the esophagus and the duodenum) showed pronounced tissue-specific
