| 摘 要： | 为建立同时检检测食源性动物组织中猪瘟病毒(CSFV)和猪蓝耳病病毒(PRRSV)的双色荧光定量RT-PCR方法。本研究根据SCFV和PRRSV基因序列设计特异性的引物和不同荧光标记的TaqMan荧光探针,通过优化反应的体系和扩增条件,建立了能够检测食源性动物组织中SCFV和PRRSV的双重双色荧光定量PCR的方法。其检测下限为1×102拷贝/μL,而且与其他一些猪病病毒无交叉反应,具有良好的特异性。该方法重复性和稳定性试验表明其组内和组间的变异系数最高分别为4.2和4.5。对比试验表明,该方法对CSFV和PRRSV检验的敏感性为常规RT-PCR方法的200倍;该方法的建立为食源性动物组织中CSFV和PRRSV提供了有效手段,该方法特异性和敏感性较好,能够应用于临床检测。

| Abstract: | To establish the method of real-time PCR for detection of classical swine fever virus(CSFV) and porcine reproductive and respiratory syndrome virus(PRRSV) in food-oriented animal tissues,the specific primers and TaqMan fluorescent probes of CSFV and PRRSV were designed and synthesized,and the amplification systems were optimized.The duplex real-time RT-PCR was established based on dual labeled FAM or VIC fluorescent probes.The method established in this study showed better amplification efficiency in detect... |
