为了建立一种便捷、灵敏的犬流感病毒(CIV)检测技术,本研究根据CIV相对保守的M片段设计3对特异性引物,建立CIV的RT-LAMP检测方法,对反应体系中的MgSO4、Betaine、Bst DNA PoLymerase、dNTP、引物浓度等分别进行了优化,并进行敏感性和特...为了建立一种便捷、灵敏的犬流感病毒(CIV)检测技术,本研究根据CIV相对保守的M片段设计3对特异性引物,建立CIV的RT-LAMP检测方法,对反应体系中的MgSO4、Betaine、Bst DNA PoLymerase、dNTP、引物浓度等分别进行了优化,并进行敏感性和特异性试验。结果表明:所建立的反应体系在恒温水浴锅中作用45min即可得到其特有的阶梯状条带,而且对犬细小病毒、犬瘟病毒和犬副流感病毒的扩增结果均为阴性。该方法对CIV RNA的最小检测限为0.1pg,灵敏性高于一步RT-PCR方法。RT-LAMP和普通RT-PCR方法检测临床样品的符合率为93.02%。该方法为犬流感病毒的临床检测提供了一种简便、实用的方法,为基层检疫提供了方便。展开更多
