摘要:   目的 获取具有抗原性的旋毛虫新生幼虫基因。 方法 以旋毛虫感染猪血清为抗体探针,对旋毛虫新生幼虫cDNA文库进行免疫筛选,将获得的阳性克隆进行测序及分析。结果 从45×105旋毛虫新生幼虫cDNA文库重组子中共获得158个阳性克隆。序列分析结果表明,其中有36个新的cDNA序列,已报道的序列有5个,有12个序列无开放阅读框架(ORF),与旋毛虫线粒体基因组DNA同源。 结论 获得具有抗原性的旋毛虫抗原编码cDNA分子

Abstract:  Objective To obtain antigenic genes encoding newborn larvae antigens of Trichinella spiralis. Methods Newborn larvae(NBL) cDNA library of Trichinella spiralis was screened using the infected swine serum and positive clones were sequenced and analysed. Results 158 positive clones were obtained from 45×105 recombinant clones by immunoscreening. The sequence analysis of positive clones showed that there are 36 novel cDNAs, 5 reported cDNAs and 12 cDNAs without the ORF showing high similarity to the mitochondrial DNA of Trichinella spiralis. Conclusion Some cDNAs encoding antigenic protein of newborn larvae of Trichinella spiralis were obtained.
