摘要: 目的 分析吉林省大林姬鼠携带的汉坦病毒(HV)在进化过程中的系统发生关系。方法 采用病毒分离技术、逆转录聚合酶链反应(RT PCR)、克隆以及测序技术对中国大林姬鼠携带的HV进行研究。结果 从4只大林姬鼠HV抗原阳性的肺组织标本中分离到2株HV(CJI89和CJI93),对其中CJI93病毒株的S片段进行克隆、测序以及分析,基因分型结果为汉滩型(HTN)汉坦病毒。根据S片段的核苷酸序列同源性分析,CJI93与Aa2499核苷酸序列的同源性最高(94.3%),而与Ap61、Ap63的同源性最小(83.3%,82.9%)。由全S片段构建的HTN型汉坦病毒的系统发生树表明CJI93与Aa2499等俄罗斯黑线姬鼠携带的HV的亲缘关系最近,其次为中国的HTN型病毒,然后才是Ap61、Ap63等俄罗斯大林姬鼠携带的HV。结论 从我国吉林省大林姬鼠分离到的CJI93株是HTN型汉坦病毒的新亚型。

Abstract: Objective To investigate phylogenetic position of hantavirus inApodemus peninsulaefrom Jilin province. Methods Viral isolation,RT-PCR,Cloning and sequenceing were used to investigate hantavirus ofApodemus peninsulae. Results Two strains were isolated from 4 positive lung samples ofApodemus peninsulae,namely hantavirus CJI89 and CJI93. The S fragment of Hantavirus CJI93 was cloned,sequenced and analyzed.The genotype of CJI93 is HTN. The nucleotide sequences of the S fragment of CJI93 showed 94.3% identity with that of strain Aa2499 (the highest homogoly),83.3% identity with that of strain Ap61 and 82.9% identity with that of strain of Ap63 (the least homology).Phylogenetic analysis also indicated the closest relationship between CJI93 and Aa2499,which is hantavirus of RussiaApodemus agrarius,closer relationship between CJI93 and HTN hantavirus in China and the farthest relationship between CJI93 and Ap61,Ap63,which are hantavirus of RussianApodemus peninsulae. Conclusion Results showed the strain CJI93 isolated from Jilin province of China is one of the new subtypes of HTN virus.
