摘要: 目的:检测比较蚊体内的黄病毒。方法:采用RT-PCR技术及常规的C6/36细胞培养结合免疫荧光法。结果:无论实验感染的登革热病毒蚊虫标本,还是从野外捕捉的标本,均表明RT-PCR检出黄病毒的阳性率比常规法高,且快速、敏捷,操作简便;常规法检出周期长(2~3周),操作复杂、繁琐和反复多次,检出率低。但常规法能通过细胞病变,观察病毒的毒力,这是RT-PCR所不及的。结论:以RT-PCR结合常规法进行虫媒病毒的研究,将更有利于探索蚊虫与虫媒病毒的关系和内在规律。

Abstract: We have made a comparison for detecting Flaviviruses in mosquitoes between reverse transcription-polymerase chain reaction (RT-PCR) and C6/36 cell culture-McAb-IFA (conventional method).The results showed that the pasitive rates of flavivirus infection by RT-PCRwhether Dengue viruses infected mosquitoes in laboratory or naturally catched mosquitoes werehighter than that by conventional method.The duration of detected Flavivirus infection was shorterby RT-PCR than by conventional method and the operation was simpler.But toxicity of flaviviruscould be observed through cells pathological changes for the latter and it not for the former.
