摘要:

目的 了解云南省西南边境地区蚊媒分布及相关蚊媒传染病的存在及流行情况,为该病的预防控制提供科学依据。方法 2013-2015年在云南省孟连傣族拉祜族佤族自治县、勐海和江城哈尼族彝族自治县采用诱蚊灯法和人工诱捕法进行蚊虫采集,采用试剂盒提取蚊虫DNA及RNA,通过反转录-聚合酶链式反应和核苷酸序列测定方法获得病原体基因序列,采用Clustal X1.83、DNASTAR 7.1和MEGA 5.0等生物学软件进行核苷酸序列分析及系统进化分析。结果 共捕获成蚊10属39种126 893只,其中捕获三带喙库蚊104 476只、中华按蚊18 422只、白纹伊蚊1 212只、致倦库蚊891只,分别占82.33%、14.52%、1.00%和0.70%。分离出2株流行性乙型脑炎病毒(JEV),均来自三带喙库蚊,未检出疟原虫、丝虫及其他黄病毒。结论云南省边境地区蚊媒传染病媒介种类较多,三带喙库蚊和中华按蚊为优势蚊种,自然界中存在着JEV,应加强重要蚊媒监测工作。

Abstract:

Objective To investigate the distribution of mosquito vectors and prevalence of mosquito-borne diseases in the southwest border regions of Yunnan province, China, and to provide a basis for the prevention and control of such diseases. Methods From 2013 to 2015, the methods of mosquito lamp and human landing collection were used to collect mosquitoes in Dai-Lahu-Va Autonomous County of Menglian, Menghai, and Hani-Yi Autonomous County of Jiangcheng of Yunnan. A kit was used to extract DNA and RNA, and RT-PCR and nucleotide sequencing were used to obtain the gene sequence of pathogens. Biological software including Clustal X1.83, DNASTAR 7.1, and MEGA 5.0 were used for nucleotide sequence analysis and phylogenetic analysis. Results A total of 126 893 mosquitoes of 39 species in 10 genera were collected, among which there were 104 476 Culex tritaeniorhynchus mosquitoes (82.33%), 18 422 Anopheles sinensis mosquitoes (14.52%), 1 212 Aedes albopictus mosquitoes (1.00%), and 891 Cx. pipiens quinquefasciatus mosquitoes (0.70%). Two strains of Japanese encephalitis virus (JEV) were isolated from Cx. tritaeniorhynchus, and Plasmodium, filaria, and other flaviviruses were not detected. Conclusion There are various vector mosquitoes in the border regions of Yunnan. Cx. tritaeniorhynchus and An. sinensis are dominant species in the local area. The isolated JEV suggest that the virus be prevalen in the southwest border regions of Yunnan, and therefore, the monitoring of key vector mosquitos should be enhanced.
