针对火鸡疱疹病毒(HVT )特异性的 sorf 1区基因序列设计引物,建立检测 HVT 的SYBR Green Ⅰ实时荧光定量PCR方法,并对其特异性、敏感性和重复性试验验证。结果表明,建立的实时荧光定量 PC R方法标准曲线的循环阈值(C t )与模版拷贝数呈良好线性关系(r2=0.99),熔解曲线分析显示该PC R扩增具有良好的特异性、敏感性和重复性,试验表明该方法最低检测浓度为7×101拷贝/μL。利用该方法对野生型 HVT和rHVT‐pmpD‐N在体内和体外的复制特性检测,结果表明重组后的HVT与野生型HVT的增殖速度基本一致。本试验建立的检测方法能够快速检测 HV T ,准确率高,特异性好,具有较高的灵敏度和稳定性,为监测HV T体内和体外的病毒含量和复制情况提供了一种有效的手段。
針對火鷄皰疹病毒(HVT )特異性的 sorf 1區基因序列設計引物,建立檢測 HVT 的SYBR Green Ⅰ實時熒光定量PCR方法,併對其特異性、敏感性和重複性試驗驗證。結果錶明,建立的實時熒光定量 PC R方法標準麯線的循環閾值(C t )與模版拷貝數呈良好線性關繫(r2=0.99),鎔解麯線分析顯示該PC R擴增具有良好的特異性、敏感性和重複性,試驗錶明該方法最低檢測濃度為7×101拷貝/μL。利用該方法對野生型 HVT和rHVT‐pmpD‐N在體內和體外的複製特性檢測,結果錶明重組後的HVT與野生型HVT的增殖速度基本一緻。本試驗建立的檢測方法能夠快速檢測 HV T ,準確率高,特異性好,具有較高的靈敏度和穩定性,為鑑測HV T體內和體外的病毒含量和複製情況提供瞭一種有效的手段。

The purpose of this study was to develop a real‐time PCR assay to detect and quantify herpesvir‐us of turkey(HVT)in vivo and in vitro targeting the unique sorf 1 gene of the virus .This assay was carried out using a LingtCycler instrument and the product was monitored constinuously with the fluorescent double‐stranded DNA binding dye SYBR Green Ⅰ .The duplicate character of wild HVT and recombinant HVT‐pmpD‐N(rHVT‐pmpD‐N)was detected using this method .Standard curve was established and the correlation index was 0 .99 .The result showed that SYBR Green Ⅰ real‐time PCR had a minimum detec‐tion limit of 7 × 101 copies/μL which was 10 times higher in sensitivity than standard PCR .SYBR Green Ⅰreal‐time PCR assay also showed a similar replication rate between wild HVT and rHVT‐pmpD‐N .It was concluded that this could be an effective ,economic and reliable method for rapid detection of wild HVT and recombinant HVT .
