新出现的 RNA 病毒的治疗受到高突变和复制率的阻碍,而高突变率和复制率使这些病毒能够作为准种发挥作用。蜜蜂数量下降归因于外寄生螨瓦螨及其与变形翅病毒(DWV)的关系。在当前的研究中,我们使用下一代测序来研究已知遭受越冬蜂群损失的养蜂场中的 DWV 准种。我们证明 DWV 物种复合体由三个主要变体组成。我们的结果表明,新的 DWV C 型变体与之前描述的 A 型和 B 型不同,但与 iflaviridae 的其他成员相比,它们一起形成了一个独特的进化枝。分子钟估计预测 C 型在大约 319 年前就与其他变体发生了分歧。 DWV 新主变种的发现对于在全球蜜蜂种群中积极鉴定真正的病原体具有重要意义。
Treatment of emerging RNA viruses is hampered by the high mutation and replication rates that enable these viruses to operate as a quasispecies. Declining honey bee populations have been attributed to the ectoparasitic mite Varroa destructor and its affiliation with Deformed Wing Virus (DWV). In the current study we use next-generation sequencing to investigate the DWV quasispecies in an apiary known to suffer from overwintering colony losses. We show that the DWV species complex is made up of three master variants. Our results indicate that a new DWV Type C variant is distinct from the previously described types A and B, but together they form a distinct clade compared with other members of the Iflaviridae. The molecular clock estimation predicts that Type C diverged from the other variants ∼319 years ago. The discovery of a new master variant of DWV has important implications for the positive identification of the true pathogen within global honey bee populations.
