在这里，我们提供了第一个证据表明，黑皇后细胞病毒（BQCV），最流行的蜜蜂病毒之一，可以引起大黄蜂，熊蜂感染，BQCV感染可以传播到大黄蜂的不同组织。检测B肠道中BQCV的负链RNA，这是病毒复制活跃的指标。Huntii认为病毒颗粒在肠道内复制，然后通过血淋巴循环穿过肠道内壁到达其他组织。观察到肠道中BQCV的活跃复制，以及BQCV在野外收集的蜜蜂体内比实验室饲养的蜜蜂更广泛的事实，意味着熊蜂的觅食活动与病毒传播之间可能存在关联。熊蜂和蜜蜂能够在同一领域共享花蜜和花粉资源的事实表明，两种宿主物种的地理接近可能在BQCV的宿主范围宽度中发挥作用。
Here we provide the first evidence that Black Queen Cell Virus (BQCV), one of the most prevalent honey bee viruses, can cause an infection in bumble bees, Bombus huntii, and that the BQCV infection could spread to different tissues of bumble bees. The detection of negative strand RNA of BQCV, an indicator of active virus replication, in the gut of B. huntii suggests that virus particles replicate within the gut and then cross the gut lining to other tissues through hemolymph circulation. The observation of active replication of the BQCV in the gut, together with the fact that BQCV was more widespread in the body of field-collected bees than that of lab-reared bees, implies a possible association between the foraging activities of bumble bees and virus transmission. The fact that bumble bees and honey bees are able to share nectar and pollen resources in the same field suggests that geographical proximity of two host species could play a role in host range breadth of BQCV.
