One DRV strain was isolated from Sika Deer brain and sequenced. Nine overlapped gene fragments were amplified by RT-PCR through 3'-RACE and 5'-RACE method, and the complete DRV genome sequence was assembled. The length of the complete genome is 11863bp. The DRV genome organization was similar to other rabies viruses which were composed of five genes and the initiation sites and termination sites were highly conservative. There were mutated amino acids in important antigen sites of nucleoprotein and glycoprotein. The nucleotide and amino acid homologies of gene N, P, M, G, L in strains with completed genomie sequencing were compared. Compared with N gene sequence of other typical rabies viruses, a phylogenetic tree was established . These results indicated that DRV belonged to gene type 1. The highest homology compared with Chinese vaccine strain 3aG was 94%, and the lowest was 71% compared with WCBV. These findings provided theoretical reference for further research in rabies virus.
从梅花鹿脑中分离出一株鹿狂犬病病毒(DRV)并进行测序。通过3'-RACE和5'-RACE方法,利用RT-PCR扩增出9个重叠基因片段,拼接得到DRV的全基因组序列。全基因组长度为11863bp。DRV的基因组结构与其他狂犬病病毒相似,由5个基因组成,起始位点和终止位点高度保守。核蛋白和糖蛋白的重要抗原位点存在氨基酸突变。比较了已完成全基因组测序毒株的N、P、M、G、L基因的核苷酸和氨基酸同源性。与其他典型狂犬病病毒的N基因序列比较,构建了系统进化树。结果表明,DRV属于基因1型。与中国疫苗株3aG的同源性最高为94%,与WCBV的同源性最低为71%。这些研究结果为狂犬病病毒的进一步研究提供了理论参考。
