摘要:   目的 将斑点金免疫渗滤法用于检测囊虫抗体 ,以制备囊虫病诊断试剂盒。方法 经透析的猪囊尾蚴囊液作为检验抗原 ,对 71份囊虫病患者、90份正常人和 2 0份其他病患者血清进行了斑点金免疫渗滤法检测并与酶联免疫吸附法比较。结果 斑点金免疫渗滤法的敏感性为 90 .1% (6 4 / 71) ,特异性为 95 .6 % (86 / 90 ) ,其他病患者血清反应中仅 1例脑肿瘤患者血清阳性 ,其余为阴性。斑点金免疫渗滤法和酶联免疫吸附法的符合率为94 .4 % (15 2 / 16 1)。结论 斑点金免疫渗滤法有较好的应用于临床检测囊虫病的潜力

Abstract:  Objective To detect serum antibody of cysticercosis by dot immunogold filtration assay for establishing a diagnostic kit for cysticercosis patients. Methods Cyst fluid of cysticercus of Taenia solium after dialysis was used as diagnostic antigen in dot immunogold filtration assay and enzyme linked immunosorbent assay to detect the serum antibody in patients with cysticercosis. Samples to be detected included 71 sera from patients with cysticercosis, 90 sera from healthy people, 20 sera from patients with other parasitic infections or brain tumor. Results The sensitivity and specificity of dot immunogold filtration assay were 90.1%(64/71)and 95.6%(86/90), respectively. No positive reaction was recorded in cases with other diseases except one serum from a patient with brain tumor. The coincidence rate between dot immunogold filtration assay and enzyme linked immunosorbent assay was 94.4%(152/161). Conclusion Dot immunogold filtration assay showed promising result for the diagnosis of cysticercosis.
