本文采用细菌学和血清学方法检测了２１７例胃、十二指肠疾病患者和１６９例健康输血员幽门螺旋菌（ＨｅｌｉｃｏｂａｃｔｅｒｐｙｌｏｒｉＨＰ）感染情况和ＡＢＯ血型，以探讨ＨＰ感染与ＡＢＯ血型系统之间的关系。结果表明：消化性溃疡各组患者Ｏ型血所占的比例均较高；胃十二指肠疾病患者和健康输血员中Ｏ型血人群ＨＰ阳性率分别为８９．５８％和５１．７８％，显著高于其它血型（Ｐ＜０．００５、０．０５）；并且在同一疾病中ＨＰ阳性者Ｏ型血所占的比例显著高于ＨＰ阴性者（Ｐ＜０．０２５）。提示：Ｏ型血人群对ＨＰ易感染，这可能是Ｏ型血患者胃粘膜上皮细胞表面较非Ｏ型血人群有更多的ＨＰ受体所致。
In this paper, 217 cases of gastric and duodenal diseases and 169 cases of healthy blood transfusion workers Helicobacter pylori HP infection and ABO blood group were detected by bacteriological and serological methods to explore the relationship between HP infection and ABO blood group system . The results showed that the proportion of O-type blood in all the patients with peptic ulcer was high, and the positive rates of HP in patients with gastroduodenal disease and those with O blood in healthy blood transfusion were 89.58% and 51.78% (P <0.005, 0.05), and the proportion of O-positive blood in HP positive group was significantly higher than that of negative HP in the same disease (P <0.025). Tip: O blood group susceptible to HP infection, which may be O blood type gastric epithelial cells in patients with more than non-O blood groups have more HP receptors.
