Detection of Hantavirus Genome by New Pairs of Hantavirus Universal Primers in HFRS Patients Serum

摘要

目的:提高汉坦病毒(HV)的检出率。方法:设计了两对新的汉坦病毒(HV)通用引物,建立新的RT-PCR方法,对流行于湖北省不同地区的肾综合征出血热(HFRS)患者血清进行了检测。结果:在对166份血清中HV RNA的检测显示HTN型阳性率为80.1%(133/166),SEO型为19.9%(33/166);对不同浓度的HV RNA检测结果显示,本法最低可检测出血清中72 pg病毒基因组。结论:说明本法用于检测HFRS患者血清中HV RNA的特异性和敏感性均很高,且我国中部地区HFRS流行以HTN为优势型,这一结果不仅为HFRS的诊断提供了新的手段,也为HFRS的防治提供了新的依据。 【英文摘要】 Objective: To improve the detection rate of Hantavirus.Methods: Two new pairs of Hantavirus universal primers was designed to detect the Hantavirus genome RNA in hemorrhagic fever with renal syndrome(HFRS) patient s serum in Hubei Province by RT-PCR.Results: In the 166 serum,80.1%(133/166) were detected to be HTN and 19.9%(33/166) were SEO in serology typing.At the same time,even a low level of Hantavirus genome RNA(≥72 pg) could be detected by this method.Conclusion: It is an excellent method to detect Han...
