摘要
To discriminate goatpoxvirus (GPV) and sheeppoxvirus (SPV), the p32 genes and G-protein-coupled chemokine receptor (GpCR) genes amplified from three SPV field isolates and two GPV field isolates were sequenced and compared with the corresponding sequences deposited in GenBank. Comparison of Hinf I restriction enzyme sites of p32 genes showed that there were two sites located at 391 and 691 bp, respectively, among all the SPV strains, and one site at 688 bp among GPV strains. Cladogram generated by sequence alignment of GpCR genes showed that the SPV and GPV belonged to two different branches. These results indicate that p32. and GpCR genes can be candidates used for discrimination of GPV and SPV.
