摘要: 本试验旨在建立一种可同时检测猪繁殖与呼吸综合征病毒(porcine reproductive and respiratory syndrome virus,PRRSV)、猪圆环病毒2型(porcine circovirus type 2,PCV2)、猪伪狂犬病病毒(porcine pseudorabies virus,PRV)、猪肺炎支原体(Mycoplasma hyopneumoniae,Mh)的多重PCR检测方法。参考相关文献合成PRRSV、PCV2、PRV、Mh的特异性引物,通过对反应条件优化、特异性、敏感性测定,建立了可同时检测以上4种猪多发传染病的PCR诊断方法。扩增的片段长度分别为424 bp (PRRSV)、490 bp (PCV2)、298 bp (PRV)和360 bp (Mh),对其他常见猪病病原无特异性扩增,采用Multiplex PCR Master Mix对PRRSV、PCV2、PRV、Mh的核酸最低检出量为3个拷贝。采用多重PCR方法对60份临床样本反复检测,与单重PCR相比,4种病原符合率均为100%。结果表明,建立的多重PCR诊断方法可用于猪群中上述4种病原的单一或混合感染的快速鉴别诊断和流行病学调查。

Abstract: The aim of this study was to establish a multiplex PCR method for simultaneously detecting porcine reproductive and respiratory syndrome virus (PRRSV),porcine circovirus type 2 (PCV2),porcine pseudorabies virus (PRV) and Mycoplasma hyopneumoniae (Mh).Four pairs of primers were synthesized according to the reference.The multiplex PCR method was developed by optimizing the reaction condition,specificity and sensitivity detection.Four different amplicons with size of 424,490,298 and 360 bp for PRRSV,PCV2,PRV and Mh,respectively,were yielded.The sensitivity of multiplex PCR indicated that the detection limit was 3 copies by using Multiplex PCR Master Mix,and other common pathogens were not amplified.A total of 60 specimens from piglets were tested by multiplex PCR method.The positive accordance rate between simple and multiplex PCR was 100%.This study indicated that multiplex PCR might be a useful tool for rapid and sensitive etiological diagnosis and provided an effective technical support for pathogenic molecular epidemiology investigation.

Key words: porcine reproductive and respiratory syndrome virus (PRRSV); porcine circovirus type 2 (PCV2); porcine pseudorabies virus (PRV); Mycoplasma hyopneumoniae (Mh); multiplex PCR; detection
