Viral infections are commonly associated with honey bee (Apis mellifera) colony mortality. Using metagenomics, we previously identified 8 viruses from populations of honey bees and 11 other bee species around the world. These viruses had not been previously been described as bee-infecting viruses, and belong to viral families that are not commonly described in bees. To provide a fine-scale characterization of these viruses in the USA, we screened bees from the 2015 USDA National Honey Bee Disease Survey. Two viruses are widespread, and thus likely require further characterization, while four may represent emerging or under surveyed infections. We also compare different approaches for screening samples for viral infections. This study demonstrates the importance of creating and maintaining large-scale collections for the broader research community.

最近发现的蜜蜂感染病毒在美国管理的蜜蜂（Apis mellifera）种群中的分布

病毒感染通常与蜜蜂（Apis mellifera）群体死亡率有关。使用宏基因组学，我们之前从蜜蜂种群和世界各地的 11 种其他蜜蜂物种中鉴定了 8 种病毒。这些病毒以前没有被描述为感染蜜蜂的病毒，它们属于蜜蜂中不常见的病毒家族。为了在美国对这些病毒进行精细的表征，我们从 2015 年美国农业部全国蜜蜂疾病调查中筛选了蜜蜂。两种病毒很普遍，因此可能需要进一步表征，而四种可能代表新出现或调查中的感染。我们还比较了筛选病毒感染样本的不同方法。这项研究证明了为更广泛的研究界创建和维护大型馆藏的重要性。
