| 摘 要： | 采用nested-PCR从猕猴肾组织细胞中获得同源性较高、具有高度保守序列的、长度为465 bp 大小的猴泡沫病毒SFV-1的 pol 基因的cDNA,将其克隆到pMD18-T载体中,并对其进行序列分析,分析结果表明所克隆的基因片断为猴泡沫病毒SFV-1 pol 基因片段,与文献中已发表的来源于灵长类动物SFV-1、SFV-1A、SFV-1B、SFV-2、 SFVmac、SFVkm的 pol 基因核苷酸序列进行比对,显示SFVkm1与上述病毒 pol 基因核苷酸同源性分别为91.06%、90.59%、90.82%、90.21%、89.41%、91.53%.对 pol 基因克隆和序列分析是了解和掌握SFV病毒分子流行病学及其变异趋势的重要手段,7 种不同基因型的泡沫病毒的系统进化树分析显示了SFVkm1与它们之间的相互联系.

| Abstract: | A 465 bp DNA segment was obtained by nested PCR from kidney culture of rhesus monkey using primers homologies to highly conserved portions of pol gene of simian foamy virus type 1 provirus,and clone it into the vector pMD18-T for sequencing.The pol gene was identified by comparison with other primate foamy viruses.The sequence comparison with the pol gene of SFV-1,SFV-1A,SFV-1B,SFV-2,SFVmac,SFVkm showed nucleotide homologies of 91.06%,90.59%,90.82%,90.21%,89.41%,91.53% respectively.We conclude that limited ... |
