摘要:   目的 建立一种检测华支睾吸虫病血清抗体的简便、快速、敏感和特异的新方法。方法 以华支睾吸虫成虫抗原为包被抗原 ,金标记葡萄球菌A蛋白 (SPA)为显色剂 ,建立检测华支睾吸虫病患者血清抗体的斑点金免疫渗滤法 (DIGFA) ;并以dot ELISA作平行对照。结果 DIGFA和dot ELISA分别检测 119例华支睾吸虫病患者血清抗体 ,其阳性率分别为 96 6 %和 92 4% ,两法差异无显著性。DIGFA分别检测正常人血清 40例、囊虫病患者血清 2 0例、日本血吸虫病患者血清 2 5例 ,前者均为阴性 ,后两者的交叉反应率分别为 5 %和 4%。DIGFA与dot ELISA两法的符合率达 90 9%。结论 DIGFA的敏感性和特异性与dot ELISA相近 ,且具简便、快速及不需特殊设备等优点 ,是一种检测华支睾吸虫病患者血清抗体的新方法。

Abstract:  Objective To establish a new, fast,sensitive and specific assay for detecting antibodies in clonorchiasis.Methods Using Clonorchis sinensis adult worm antigen and SPA labelled with colloidal gold as color developing agent,a dot immunogold filtration assay (DIGFA) for detecting clonorchiasis antibodies was tested. Dot-ELISA was used as the parallel control.Results The positive rate of DIGFA and dot-ELISA in testing the sera from 119 proved cases were 96.4%(115/119) and 92.4%(110/119), respectively,the difference between the two assays being in significant ( P >0.05). The negative rate of DIGFA in healthy people was 100%(40/40). The cross reaction rate in 20 cysticercosis cases and 25 schistosomiasis cases were 5%(1/20) and 4%(1/25), respectively. Both coincidence rates comparing DIGFA with dot-ELISA were 90.9%(50/55). Conclusion DIGFA is as sensitive and specific as the dot-ELISA,and has the advantages of simplicity and without specific equipment.
