Abstract
Based on the variant sequences of PRRSV JXA1 strain and the genetic markers of JXA1-R strain, two pairs of primers were designed and synthesized,and RT-PCR methods were established for detecting the two viruses with specific gene fragments of 400 bp and 290 bp.There was no cross-reactions with those clinically relevant pathogens,such as classical swine fever virus, porcine pseudorabies virus, porcine circovirus type 2, porcine parvovirus.The sensitivity tests showed that the assay could detect 103 copies/μL RNA of JXA1 and 104 copies/μL RNA of JXA1-R.The RT-PCR established in this study, with high specificity and sensitivity,was very suit for clinic-sample detection.关键词
