摘要: 参照已发表的扩增伪狂犬病毒(pseudorabies virus, PRV)gB和gD表位基因的PCR扩增引物合成2对引物,以福建分离株(LY株)提取的DNA为模板,得到目的片段gB、gD基因的长度分别为578和653 bp,并进行了克隆和测序,然后与国内外其他分离株进行了核苷酸序列及推导的氨基酸序列的同源性分析,并构建了遗传进化关系图。结果表明,LY株与GenBank中收录的国内外有代表性的标准参考分离株相比,gB、gD基因核苷酸序列的同源性分别为74.9%~98.8%、97.2%~98.1%;氨基酸序列的同源性分别为62.9%~96.4%、94.5%~96.8%。进化分析结果表明,LY株与目前国内流行的毒株在同一个进化分支内,和Ea株(湖北)、LA株(山东)亲缘关系最近,与国外分离株有一定差异。

Abstract: The gB and gD antigen epitope genes of pseudorabies virus (PRV) Fujian strain(LY strain) were amplified by PCR, the paraments of gB and gD were cloned into pMD18-T easy and sequenced,getting about 578 and 653 bp DNA fragments, then the gB and gD gene of PRV LY strain were cloned and sequenced. Compared with gB and gD antigen epitope genes in GenBank, the sequence analysis determination show that the gB and gD gene of LY strain shares 74.9% to 98.8% and 97.2% to 98.1% nucleotide homology, 62.9% to 96.4% and 94.5% to 96.8% amino acid sequence homology with other strains. The evolutionary analysis indicated that LY strain had the same evolutionary branch with domestic epidemic strains, and had a close relationship with the Ea strain (Hubei), LA strain (Shandong) isolated from domestic strains other than from abroad.
