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.
