摘要
为了快速鉴别诊断高致病性猪繁殖与呼吸综合症,参照GeneBank已发表的猪繁殖与呼吸综合征病毒(PRRSV)的Nsp2基因,设计了1对引物,建立了一种RT-PCR检测方法.该方法可以区分高致病性PRRSV毒株与经典PRRSV弱毒疫苗株,扩增PCV2、PRV、PPV和CSFV等均为阴性.该方法敏感性较高,可以检测到0.2 ng的病毒核酸.
A pair of primers based on Nsp2 gene of porcine reproductive and respiratory syndrome virus (PRRSV) was designed and a method of RT-PCR was developed to distinguish the highly pathogenic PRRSV from the classic attenuated vaccine strain. The method was sensitive to detect as low as 0. 2 ng viral genome. PCV2, PRV, PPV and CSFV were negative in their reactions.
