摘要
目的 建立一种多重实时荧光定量反转录聚合酶链式反应(多重实时qRT-PCR)法,用于阿龙山病毒(Alongshan virus,ALSV)及松岭病毒(Songling virus,SGLV)核酸的快速检测.方法 针对ALSV NS 3基因和SGLV S基因保守区设计特异性引物及TaqMan探针,建立针对2种病毒的多重实时qRT-PCR检测方法,评价方法的特异性、灵敏度和重复性,并应用蜱标本对该方法进行应用评价.结果 该检测方法与森林脑炎病毒等其他6种虫媒病毒无交叉反应,灵敏度达1×101 拷贝/μl,重复性检测的循环阈值(Ct)变异系数均<2.00%;运用该方法,从2019年黑龙江省采集的30组蜱标本中检出2组ALSV阳性,1组SGLV阳性.经验证,该方法与普通PCR方法检测结果的一致性为100%.结论 建立了敏感性高、特异性好的ALSV和SGLV多重实时qRT-PCR快速检测方法.
Abstract
Objective To establish a multiplex real-time fluorescent quantitative reverse transcription polymerase chain reaction(multiplex real-time qRT-PCR)method for rapid detection of nucleic acids of Alongshan virus(ALSV)and Songling virus(SGLV).Methods Specific primers and TaqMan probes were designed for the conserved regions of the NS 3 gene of ALSV and the S gene of SGLV.A multiplex real-time qRT-PCR method was established for the two viruses,and the specificity,sensitivity,and repeatability of the method were evaluated.Tick specimens were used to verify the method.Results The detection method had no cross-reactivity with six other arboviruses,such as tick-borne encephalitis virus,with a sensitivity up to 1×101 copies/μl,and the coefficient of variation of cycle threshold for repeatability testing was less than 2.00%.Through this method,two groups of ALSV-positive specimens and one group of SGLV-positive specimens were detected from 30 groups of tick specimens collected from Heilongjiang,China in 2019.This method was verified to be 100%consistent with the general PCR method in terms of test results.Conclusion In this study,a highly sensitive and highly specific multiplex real-time qRT-PCR method for rapid detection of ALSV and SGLV has been successfully established.
