| 目的 测试抗狂犬病毒核蛋白单克隆抗体用于间接免疫荧光法检测已确认的狂犬病阳性及狂犬病阴性的动物脑组织标本的灵敏度和特异性。方法 将巴斯德研究所狂犬病参考中心保存的来自不同国家的 6 2份狂犬病街毒动物脑组织标本以及 2 71份法国境内收集的正常动物脑组织标本,用上述间接免疫荧光检测,并以巴斯德研究所狂犬病参考中心提供的狂犬病毒酶联免疫吸附法、组织细胞分离法及直接免疫荧光法等三个试验作确认试验,进行比较。结果 间接免疫荧光法可检测涵盖狂犬病毒 7个基因型在内的所有 6 2份街毒标本,对确认为狂犬病阴性的动物脑组织标本检测均为阴性,其特异性和灵敏度均达到 10 0 %。结论 抗狂犬病毒核蛋白单抗作为间接免疫荧光法检测狂犬病毒具有良好的应用前景。 |

| Objective McAbs against rabies nucleocapsid were used to detect rabies street viruses in animal brain specimens with indirect immunofluorescent assay to evaluate the sensitivity and specificity of this assay. Methods 62 specimen from rabid animal brains including genotype 1 to 7 and 271 specimens from different normal animal brains collected in Pasteur Institute in 2003 were tested and compared, using indirect immunofluorescent assay. All these specimens were identified and compared using rapid rabies enzyme immunodiagnosis, fluorescent antibody test and rabies virus isolation assay in neuroblastoma cell culture which were all provided by Pasteur Institute. Results Both sensitivity and the specificity of the indirect immunofluorescent assay were 100%. Conclusion The results showed a positive of rabies virus detection with these methods. |
