摘要: 目的 用重组日本血吸虫相对分子质量(Mr)29 000膜外蛋白(rSj29)作为诊断抗原,探讨其在血吸虫病流行区免疫诊断的价值。 方法 在血吸虫病低度流行区芜湖南陵县弋江镇蒲桥和竞河村现场采血394份,同时采集粪样,用改良加藤法(三送九检)或集卵孵化法检查。制备rSj29和成虫粗抗原(AWA),分别用2种抗原进行间接ELISA(单盲法)和间接红细胞凝集试验(IHA)检测血样。 结果 粪检、IHA、rSj29-ELISA和AWA-ELISA检测结果显示,阳性率分别为4.8%(19/394)、 62.2%(245/394)、68.3%(269/394)和89.9%(354/394)。 rSj29-ELISA和IHA检测结果差异无统计学意义(χ2=3.2, P>0.05), 一致率为80.7%(318/394)。IHA、rSj29-ELISA和AWA-ELISA与粪检符合率分别为42.6%(168/394)、 36.0%(142/394)和15.0%(59/394)。 结论 rSj29间接ELISA法对日本血吸虫病有一定诊断价值。

Abstract: Objective To evaluate the recombinant membranous protein 29 000 (rSj29) of Schistosoma japonicum in the immunodiagnosis of schistosomiasis by indirect ELISA. Methods 394 serum samples collected from two low-endemic villages in Anhui Province were tested by rSj29-ELISA and AWA-ELISA using adult worm antigen (AWA) of S. japonicum. Meanwhile all subjects were each tested by 9 examinations with 3 fecal samples by modified Kato-Katz method, and by indirect hemagglutination assay (IHA). Results It was found that the positive detection rates of stool examination, IHA, rSj29-ELISA and AWA-ELISA were 4.8% (19/394), 62.2% (245/394), 68.3% (269/394), and 89.9%(354/394), respectively. There was no statistical difference between rSj29-ELISA and IHA (χ2=3.2, P>0.05) with the coin-cidence of 80.7%(318/394). The coincidence of IHA, rSj29-ELISA and AWA-ELISA with stool examination was 42.6% (168/394), 36.0% (142/394), and 15.0% (59/394), respectively. Conclusion The indirect ELISA with rSj29 antigen shows similar effect as IHA for the diagnosis of schistosomiasis.
