    荷斯坦牛脊椎畸形综合征TaqMan荧光PCR检测方法的建立与应用

    Establishment and application of TaqMan real-time PCR to detect the complex vertebral malformation in Holstein cattle

      摘要
    • 摘要:
      目的 建立快速筛查牛脊椎畸形综合征（Complex vertebral malformation，CVM）基因携带者的方法，在牛群中逐渐淘汰CVM基因携带者以减少养牛业损失.
      方法 根据GenBank已发表的CVM基因的SLC35A3基因序列，设计合成了2对特异性引物和2条TaqMan探针，建立了牛脊椎畸形综合征TaqMan探针检测方法.对方法的特异性和敏感性进行分析后，应用该方法对临床样本进行检测，并与测序方法进行比较.
      结果和结论 该方法能有效区分突变型、野生型和杂合型个体.各种基因型的检测灵敏度为：突变型质粒拷贝数1 × 103 μL-1，杂合型质粒拷贝数1 × 104 μL-1，野生型质粒拷贝数5 × 103 μL-1.从292份荷斯坦牛全血中检出6份CVM基因携带者，与测序方法结果一致.本研究建立的方法简便快捷、准确率高，适合大样本筛选和口岸现场快速筛查.

       

      Abstract:
      Objective The objective of this study was to establish a rapid assay to detect complex verte-bral malformation(CVM)gene carrier so as to gradually eliminate CVM gene carriers for a lower loss in the cattle-feeding industry.
      Method In this study, a pair of primer and two TaqMan probes were de-signed according to the sequence of SLC35A3 gene from GenBank.A TaqMan real-time PCR assay for CVM gene was developed.DNA samples from clinical Holstein cattles were analysed by the assay, and the results were used for comparison with sequencing method.
      Result and conclusion The assay could effectively differentiate mutant type, wild type and hybrid type of CVM gene.The sensitivity of three types was 1 × 103, 5 × 103and 1 × 104 μL-1, respectively.Six out of 292 tested Holstein cattles were iden-tified to be CVM gene carriers.The results were consistent with the sequencing method.The TaqMan real-time PCR is a rapid and reliable method for extensive screening of CVM gene at the port of entry.
