摘要
Abstract
The most recent researches showed that atypical porcine pestivirus(APPV) was prevalent in swine herds in China and caused serious losses.In this research,thewhole genome of APPV GD3 strain was amplified by RT-PCR,and the genome sequence and its partial coding genes were genetically analyzed.According to the structural protein E2 gene sequence encoded by APPV genome,a real-time RT-PCR method was established for detection of APPV.The whole genome sequence of APPV shared from 83.1%to 83.4% homology with German,American,Dutch and Spanish strains and APPV located at a different branch.The homologies between GD3 and GD1,GD2 and GD strains were 99.5%,99.6% and 83.4%,respectively.The homology of E2,Npro and Erns encoded by GD3 strains of APPV with currently available strains were from 83.1%to 99.7%,80.2%to 99.8%and 81.9%to 99.5%,respectively.The real-time RT-PCR method established inthisstudywashighly specific,simple,time-saving and the detection limit was 10 copies /μL.It will be well used in veterinary clinical detection.关键词
