To sequence and analyze the full-length gene sequence of rabies vaccine virus aG strain. The full-length gene sequence of aG strain was amplified by RT-PCR by 8 fragments,each PCR product was cloned into vector pGEM-T respectively, sequenced and assemblied; The 5' leader sequence was sequenced with method of 5' RACE. The homology between aG and other rabies vaccine virus was analyzed by using DNAstar and Mega4. 0 software. aG strain was 11 925nt(GenBank accession number: JN234411) in length and belonged to the genotype I . The Bioinformatics revealed that the homology showed disparation form different rabies vaccine virus. the full-length gene sequence of rabies vaccine virus aG strain provided a support for perfecting the standard for quality control of virus strains for production of rabies vaccine for human use in China.
对狂犬病疫苗病毒aG株全长基因序列进行测序与分析。采用RT-PCR法将aG株全长基因序列扩增为8个片段,各PCR产物分别克隆至载体pGEM-T中,进行测序与拼接;采用5′RACE法对5′前导序列进行测序。利用DNAstar和Mega4.0软件分析aG株与其他狂犬病疫苗病毒的同源性。aG株全长11 925nt(GenBank登录号:JN234411),属于基因I型。生物信息学分析显示,其与不同狂犬病疫苗病毒的同源性存在差异。狂犬病疫苗病毒aG株全长基因序列为完善我国人用狂犬病疫苗生产用毒种质量控制标准提供了依据。
