Ticks are obligate hematophagous arthropods that can transmit pathogens and are important vectors of diseases affecting wild and domestic animals, as well as humans, thus representing a serious risk to public health. Despite the growing concern about arboviruses, our understanding of tick-borne viruses remains limited compared to those transmitted by mosquitoes. We performed metagenomic analysis, focusing on the virome of ticks collected from wild animals in the countryside of the state of São Paulo, Brazil. The experimental analysis highlighted important molecular evidence of a potential new virus from the group in ticks collected from wild animals. The four pools that were positive included and ticks, collected from , and . These data suggest that it is a new member of the group, which we propose to be named Rio Preto tick virus (RPTV). In addition, the RPTV genome was analysed , and proteins with high homology to those of the group were identified. Here, we report the identification of a potentially novel virus found in ticks from wild animals in southeastern Brazil. This study contributes to the epidemiological surveillance of the region and helps to understand the potential risks of the emergence of zoonoses, which can impact human health, in addition to the potential impacts on the fauna.
蜱是专性吸血节肢动物,可传播病原体,是影响野生动物、家畜以及人类疾病的重要传播媒介,因此对公共卫生构成严重风险。尽管人们对虫媒病毒的关注日益增加,但与蚊子传播的病毒相比,我们对蜱传病毒的了解仍然有限。我们进行了宏基因组分析,重点关注从巴西圣保罗州农村野生动物采集的蜱的病毒组。实验分析突出了从野生动物采集的蜱中存在一种潜在新病毒的重要分子证据。四个呈阳性的样本池包括从[具体地点1]、[具体地点2]和[具体地点3]采集的[蜱的种类1]和[蜱的种类2]蜱。这些数据表明它是[病毒组名称]组的一个新成员,我们提议将其命名为里奥普雷图蜱病毒(RPTV)。此外,对RPTV基因组进行了分析,鉴定出与[病毒组名称]组蛋白具有高度同源性的蛋白质。在此,我们报告在巴西东南部野生动物蜱中发现一种潜在新病毒。这项研究有助于该地区的流行病学监测,并有助于了解人畜共患病出现的潜在风险,这不仅会影响人类健康,还会对动物群产生潜在影响。
