Little is known about the role of ticks in maintaining highly prevalent zoonotic viruses in wildlife, such as hepatitis E virus (HEV), which do not require ticks for transmission between animals and humans. In this cross-sectional study, adult female ticks were collected from Eurasian wild boar () in autumn 2015 in Spain. HEV RNA in both ticks and wild boar was evaluated by RT-qPCR. Twenty-nine adult ticks were collected from 29 wild boars. HEV RNA was detected in a total of 10 tick (34.4%) and 11 wild boar serum samples (37.9%). In two cases, detectable HEV RNA was found in a wild boar but not in the tick collected from them. In contrast, one HEV-positive tick was collected from an HEV-negative wild boar. All viral sequences were consistent with genotype 3f. We describe for the first time the presence of HEV RNA in adult ticks.
关于蜱虫在维持野生动物中高流行率的人畜共患病毒（如戊型肝炎病毒，HEV）方面的作用，人们所知甚少，戊型肝炎病毒在动物与人之间传播并不需要蜱虫。在这项横断面研究中，2015年秋季在西班牙从欧亚野猪（）身上采集了成年雌性蜱虫。通过逆转录定量聚合酶链反应（RT-qPCR）评估蜱虫和野猪体内的HEV RNA。从29头野猪身上采集了2-nine只成年蜱虫。在总共10只蜱虫（34.4%）和11份野猪血清样本（37.9%）中检测到了HEV RNA。在两例中，在一头野猪中检测到可检测到的HEV RNA，但从其身上采集的蜱虫中未检测到。相反，从一头HEV阴性的野猪身上采集到一只HEV阳性的蜱虫。所有病毒序列均与3f基因型一致。我们首次描述了成年蜱虫中存在HEV RNA。
