Detection of Quang Binh virus from mosquitoes in northwestern China

  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.
