摘要:

为研究马疱疹病毒1型(EHV-1-XJ2015)新疆伊犁分离株致病基因型,评估新疆EHV-1-XJ2015的潜在风险因素,本试验设计特异性引物,应用PCR技术扩增EHV-1-XJ2015分离株ORF30基因相应区域,连接至克隆载体,成功构建重组质粒pMD19-T-ORF30。测序结果表明,EHV-1-XJ2015毒株ORF30基因2 254 bp处为A,且编码天冬酰胺(N),分析证明EHV-1-XJ2015基因型为非神经型毒株,毒力倾向表现为流产型毒株;遗传进化显示,EHV-1-XJ2015毒株与日本分离株90c16、00c19、HH1、NY03为同一分支,氨基酸同源性最高为100%。本研究结果为开展EHV-1分子流行病学调查研究及为新疆地区现有诊断方法和防控措施的评估提供理论依据。

Abstract:

To study the genotypes of EHV-1-XJ2015 strain isolated from Ili area of Xinjiang, this study investigated the potential risk factors for EHV-1-XJ2015.In this experiment, specific primers was designed and using PCR technique to amplify corresponding region of EHV-1-XJ2015 isolate ORF30 gene, connected to vector pMD19-T,and the recombinant plasmid pMD19-T-ORF30 was successfully constructed. Sequencing results showed that EHV-1-XJ2015 strain ORF30 gene 2 254 bp site was A, and encoding asparagine (N).It was proved that EHV-1-XJ2015 was a non-neurotoxic strain, virulent strains tend to behave as a miscarriage. The phylogenetic analysis showed that the EHV-1-XJ2015 strain was the same branch as the 90c16, 00c19, HH1, NY03 isolated from Japan, amino acid homology was the highest and reached 100%. The results provided a theoretical basis for the study of EHV-1 molecular epidemiology and the assessment of existing diagnostic methods and prevention and control measures in Xinjiang, and ultimately achieved the purpose of prevention and control of the disease.
