摘要: 根据GenBank中发表的犬瘟热病毒Onderstepoort株融合蛋白基因(F)序列设计两对特异性引物,采用RT-PCR扩增犬瘟热病毒贵州分离株(CDV-GZ1)的F基因,并进行克隆与序列分析。结果显示,CDV-GZ1株F基因的ORF全长1989 bp,氨基酸序列中具有5个潜在N-糖基化位点,氨基酸同源性与美国00-2601株和国内HL株较高,分别为91.6%和91.1%,表明该分离株与00-2601株和HL株具有较近的亲缘关系。

Abstract: Two pairs of primers were designed and synthesized based on the sequence of the Onderstepoort strain of canine distemper virus reported in GenBank, and the F gene was amplified by reverse transcription polymerase chain reaction (RT-PCR) from CDV-GZ1 strain. The amplified fragment was cloned and analyzed. The results showed that the length of CDV-GZ1 F gene was 1989 bp. It contained five potential N-glycosylation locations based on the derived amino acid sequences. The homology of coding amino acid between this strain and American 00-2601 and domestic HL strain was 91.6% and 91.1% respectively, it showed that they had common ancestor.
