我国西北地区蚊虫标本中广平病毒的检测

Detection of Quang Binh virus from mosquitoes in northwestern China

  • 摘要:
      目的   对我国西北地区蚊虫携带病毒开展调查,并快速发现重要的蚊媒病毒。
      方法   通过形态学方法对采集蚊虫进行分类鉴定,深度测序和宏基因组分析方法分析蚊虫携带的病毒,结合Sanger测序法补全病毒基因组全序,应用系统进化分析方法分析病毒分子遗传特征。
      结果   2019年7月采集自陕西省的中华按蚊标本和宁夏回族自治区的三带喙库蚊标本均检测到黄病毒属广平病毒。 进化分析结果显示,这两株广平病毒序列与在中国辽宁省发现的广平病毒JM17156株具有较近亲缘关系,核酸序列同源性为99.8%。
      结论  本研究首次在我国西北地区中华按蚊、三带喙库蚊标本中检测到广平病毒。

     

    Abstract:
      Objective  To investigate the diversity of mosquito-borne virus in northwestern China, and identify important mosquito-borne viruses.
      Methods  The mosquitoes were identified according to morphological methods, the mosquito-borne virus was identified by deep sequencing and metagenomic analysis. Molecular genetic characteristics of identified virus were analyzed by phylogenetic method.
      Results  Quang Binh virus was detected from Anopheles sinensis collected in Shaanxi province and Culex tritaeniorhynchus collected in Ningxia Hui autonomous region in July 2019. Phylogenetic analysis showed that the two strains shared the same evolutionary branch with the JM17156 strain of Quang Binh virus identified in Liaoning province, China, with nucleotide sequence homologous of 99.8%.
      Conclusion  Quang Binh Virus were first successfully identified from Anopheles sinensis and Culex tritaeniorhynchus in Northwestern China.
