目的 研究广西罗城县各民族儿童的幽门螺杆菌 (H pylori)感染的流行率及其H pylori菌株类型的分布。方法 2 78例各民族儿童采用ELISA法及免疫印迹法联合检测血清抗体以了解H pylori感染状态。结果 该地区儿童H pylori感染的总阳性率为 6 4 4 % (1 79/ 2 78)。汉、壮、仫佬族和其他儿童的H pylori阳性率分别为 78 3% (2 9/ 37) ,6 4 9% (37/ 5 7)、5 7 3% (4 3/75 )、6 4 2 % (70 / 1 0 9,各民族儿童的感染率无显著性差异。H pylori菌株类型在各民族儿童间的分布无显著性差异。结论 广西罗城县儿童的H pylori流行率较高 ,H pylori的感染率及菌株分型与民族类别无关
Objective To study the prevalence of H pylori infection and the distribution of H pylori strains in children of all ethnic groups in LuoCheng county, Guangxi province. Method 2 78 children from all ethnic groups were tested for serum H pylori infection by ELISA and Western blot. Results The overall positive rate of H pylori infection in children in this area was 64.4% (1 79/278). The positive rates of H pylori in Han, Zhuang, Mulao and other children were 78.3% (29/37), 69.4% (37/57), 573% (4 3/75), 6 There was no significant difference in the infection rates among children of all ethnic groups in China.22% (70/109), there was no significant difference in the distribution of H pylori strains among children of all ethnic groups.Conclusion The prevalence of H pylori in children in Luocheng County of Guangxi Province is high , H pylori infection rate and strain typing has nothing to do with ethnic category
