中文摘要：

目的建立一种快速、敏感、特异的双重实时荧光定量PCR方法，可同时检测马尔堡病毒和埃博拉病毒。方法通过序列比对挑选出两种病毒基因组中高度保守的序列，分别设计引物及Taqman探针，两条探针分别标记FAM和Texas Red荧光报告基因，建立双重实时荧光定量PCR反应体系。结果双重荧光定量PCR方法检测两种病毒阳性标准品的灵敏度分别为30．5拷贝／μl和28．6拷贝／μl，通过检测日本脑炎病毒、黄热病毒、登革热病毒无交叉反应，有较好的灵敏度和特异性。结论建立了马尔堡、埃博拉病毒双重荧光定量PCR检测方法，实现了两种病毒同时实时定量检测，在传染病防控领域有较好的应用前景。

英文摘要：

Objective Marburg virus and Ebola virus are acute infections with high case fatality rates. A rapid, sensitive detection method was established to detect Marburg virus and Ebola virus by multiplex real-time fluorescence quantitative PCR. Methods Designing primers and Taqman probes from highly conserved sequences of Marburg virus and Ebola virus through whole genome sequences alignment, Taqman probes labeled by FAM and Texas Red, the sensitivity of the multiplex real-time quantitative PCR assay was optimized by evaluating the different concentrations of primers and Probes. Results We have developed a real-time PCR method with the sensitivity of 30.5 copies/μl for Marburg virus positive plasmid and 28.6 copies/μl for Ebola virus positive plasmids, Japanese encephalitis virus, Yellow fever virus, Dengue virus were using to examine the specificity. Conclusions The Multiplex real-time PCR assays provide a sensitive, reliable and efficient method to detect Marburg virus and Ebola virus simultaneously.
