摘要: 根据GenBank中犬瘟热病毒(canine distemper virus,CDV)核蛋白(N)基因序列,设计合成1对特异性引物,以CDV上海(SH)株的总RNA为模板,RT-PCR扩增N蛋白基因,并进行克隆与序列分析。结果显示:CDV SH株N蛋白基因序列与CDV TN株、 A75/17 株、2544/Han95株、98-2654 株、5804株、Onderstepoort疫苗株的同源性分别为98.9%、97.6%、96.7%、96.9%、96.6%、93.9%;编码氨基酸的同源性分别为99.0%、98.7%、98.1%、97.9%、97.9%、96.9%。推测N蛋白是一个保守性非常强的结构蛋白。

Abstract: According to the reported gene sequence of N protein of Canine Distemper Virus (CDV) in Gene Bank, a special pair of primers were designed to RT
-PCR amplify N protein gene by using the total RNA of CDV SH stain as a template. The results showed that the homology of gene sequence between CDV SH strain and TN strain was 98.9%, A75/17 stain (97.6%), 2544/Han95 strain(96.7%), 98-2654 Strain(96.9%), 5804 strain(96.6%) and Onderstepoort(93.3%) and the homology of coding amino acid between CDV SH strain and the others were respectively 99.0%,98.7%,98.1%,97.9%,97.9% and 96.9%. From this information, it can be predicted
that N protein has highly conservative property.
