Distribution and phylogenetic analysis of Dabieshan tick virus in tickscollected from Zhoushan China

摘要

Dabieshan tick virus (DBV) belongs to and its pathogenicityto human and animals is unknown. To investigate the presence of Dabieshan tick virus inZhoushan, 353 ticks were collected from May 2018 to October 2019. The detection resultshowed that the average prevalence rate among these samples was 30.3% (107 positives outof 353 samples), which means DBVs are widely distributed in tick populations in Zhoushanof China. In a phylogenetic analysis based on the nucleotide sequences of the L and Ssegments of the virus (ZS-DBS-2018 tick virus) in the study, it clustered with Dabieshantick virus ( , ) with a 97.1% and 99.6% nucleotide identity,respectively. Further studies involving virus isolation are required to characterizeDabieshan tick virus and to expand the geographical distribution of the sampled ticks.
