摘要
目的比较硅胶膜法和磁珠法在寨卡病毒核酸检测中的使用效果,以选择适合的核酸提取方法用于临床样本的寨卡病毒检测。方法对北京首例输入性寨卡病毒感染病例的尿液和唾液样本同时用硅胶膜法和磁珠法提取总RNA,用一步法和两步法实时荧光RT-PCR进行寨卡病毒核酸检测,比较检测效果的差异。结果在一步法中,用硅胶膜法从尿液中提取RNA,寨卡病毒检测阳性;用磁珠法从尿液和唾液中提取的RNA,检测均为阴性。在二步法中,用硅胶膜法从尿液和唾液中提取的RNA,检测均为阳性,而磁珠法提取的样本均未检出。结论硅胶膜法提取核酸比磁珠法更适合于寨卡病毒荧光RT-PCR检测。
Objective To compare the performance of two commonly used nucleic acid extraction methods,silica membranes column and magnetic beads,in the detection of Zika virus detection. Methods Total RNA were extracted from urine and saliva samples,which had been collected from the first imported case of Zika virus infection in Beijing,by silica membranes column and magnetic beads,respectively. One-step or two-step Real-time RT-PCR were conducted to detect Zika virus,and the performance of two extraction methods were compared. Results RNA extracted from urine sample treated by silica membranes was detected positive in one-step Real-time RT-PCR,while samples treated by magnetic beads were all negative. In two-step Real-time RT-PCR,RNA were detected positive from both urine and saliva samples extracted by silica membranes,but undetected in all samples extracted by magnetic beads. Conclusion Nucleic acid extraction by silica membranes was more effective for Zika virus detection by using Real-time RT-PCR.
