【摘要】 分析东方田鼠分离汉坦病毒ZT10株M基因分子特征。提取汉坦病毒ZT10株感染细胞的总RNA,应用逆转录聚合酶链反应(RT-PCR)扩增ZT10株M片段全基因,克隆于T载体并测序,对其进行序列分析。结果显示汉坦病毒ZT10株的基因组M片段长度为3651个核苷酸,编码1133个氨基酸。序列分析表明其为Seoul型汉坦病毒。与八株Seoul型汉坦病毒的M片段同源性为84.0%～96.3%,而与HTN型汉坦病毒的同源性则较低,与从田鼠分离的汉坦病毒(ProspectHillvirus,Tulavirus,Khabarovskvirus,Islavistavirus)核苷酸同源性仅为57.5%～60.9%,且与浙江省Seoul型分离株Guo3同源性较低,表明浙江省可能存在着另一Seoul亚型的汉坦病毒。更多还原

【Abstract】 The effects of the M gene on the molecular epidemiological characteristics of the Hantavirus ZT10 strain isolated from M. arvalis was investigated. The gene was amplified by RT-PCR and yielded the expected product of 3651 bp. The amplified fragment was then cloned into the T vector and confirmed by PCR and sequencing. Analysis of the sequence revealed that the ZT10 M segment belongs to seoul virus.The nucleotide sequence identity of this M gene with eight virus strains was 84.0%～96.3%. The identity with Hantanvirus(Prospect Hill virus, Tula virus, Khabarovsk virus, Isla vista virus) isolated from arvalis was 57.5%～60.9%. Also, the identiry with the SEO types and with the Guo3 isoated from ZheJiang province was 84.0%. Seoul virus ZT10 strain is a new specific seoul subtype virus in ZheJiang province.更多还原
