【摘要】 根据羊痘病毒(CaPV)末端反向重复序列中的一段序列和P32基因序列,设计合成了2对引物,通过确定最佳的PCR反应条件,建立了检测羊痘病毒核酸的多重PCR方法。结果显示,用这2对引物均能扩增出羊痘病毒相应的特异性片段,而用此PCR方法检测口蹄疫病毒和羊口疮病毒,结果均为阴性。与中和试验比较,建立的PCR方法具有更好的敏感性。表明,该PCR方法可对组织病料中的CaPV进行快速检测。更多还原

【Abstract】 Two pairs of specific primers were designed and synthesized according to the inverted terminal repeat sequence and p32 gene sequence of the genome of capripoxvirus(CaPV).After optimization of PCR conditions,a multiplex PCR assay for detecting the genomic DNA of CaPV was developed.The results revealed that the expected fragment could be amplified from the extracted CaPV DNA by the multiplex PCR assay developed.No PCR products were amplified from samples containing orf virus or foot-and-mouth disease virus using the assay.Compared with the neutralization tests,the multiplex PCR was more sensitive,and would be applied for rapid diagnosis of CaPV samples in biopsy and tissue cultures.更多还原
