| 摘 要： | 目的 寻求特异性强、敏感性高的旋毛虫病诊断抗原。 方法 以旋毛虫新生幼虫期特异性T668基因在E.coli高效表达的重组蛋白为抗原，分别以兔、猪和健康者血清及旋毛虫病阳性血清为一抗，以辣根过氧化物酶（HRP）标记的山羊抗兔IgG、山羊抗猪IgG和山羊抗人IgG为二抗，建立检测旋毛虫抗体的间接ELISA方法，并以旋毛虫肌幼虫排泄?鄄分泌（ES）抗原作为检测对照。 结果 以T668重组蛋白为抗原，对兔、猪和人旋毛虫病血清进行检测，阳性检出率为100 ％，且敏感性高（0.016 μg / 孔），与ES抗原检测结果完全一致。 结论 T668重组抗原有望替代ES抗原检测旋毛虫抗体。 |

| Abstract: | OBJECTIVE: To study the specificity, sensitivity of diagnostic antigen for Trichinella spiralis (T.s). METHODS: T668 recombinant protein from highly efficient expression of newborn larvae stage-specific gene of T.s in E. coli as diagnostic antigen. By using negative and positive sera from rabbit, pig, human as the first antibody, and goat-anti-rabbit IgG, goat-anti-pig IgG, goat-anti-human IgG labeled with HRP as the secondary antibody, indirect ELISA method was established for detecting anti-T.s antibody, while excretory-secretory (ES) antigen of T.s muscle larvae was used as control. RESULTS: Sera from rabbit, pig and human were detected by T668 recombinant protein as antigen, which showed a positive rate of 100% with 0.016 microg/well. There was no difference on the results between the T668 recombinant antigen and the ES antigen for diagnosing T.s-infection. CONCLUSION: The T668 recombinant antigen is promising in substituting ES antigen in the detection of anti-T.s antibody. |
