许多蜱传病毒,包括多里病毒和口蹄疫病毒,被分离出来。为了识别在肯尼亚和周边地区传播的蜱传病毒,我们在肯尼亚内罗毕的屠宰场进行了监测。蜱类种类主要有美丽扇头蜱(56%)、芽花钝眼蜱(14%)、革蜱(14%)、扇头蜱(14%)、花钝眼蜱(14%)、花钝眼蜱(14%)、花钝眼蜱(14%)、花钝眼蜱(14%)。apaculatus(8%),A.杂色花(6%)等。共分离到56株病毒,其中26株来自A. gemma,R. pulchellus,A. variegatum和7个其他物种。病毒分离株包括Dugbe病毒(DUGV),一种与DUGV、Thogoto、Bhanja、Kadam、Dhori、Barur和口蹄疫(FMDV)病毒相关的未知病毒。这是首次在东非分离到Dhori病毒,也是首次发现与蜱虫采集相关的口蹄疫病毒。我们的研究结果表明,蜱传传播的地方性和新出现的病毒的潜力和A。芽孢在维持蜱传病毒在这一地区。
Numerous tickborne viruses, including Dhori virus and foot-and-mouth disease virus, were isolated. To identify tickborne viruses circulating in Kenya and the surrounding region, we conducted surveillance at abattoirs in Nairobi, Kenya. Species of ticks collected included Rhipicephalus pulchellus (56%), Amblyomma gemma (14%), R. appendiculatus (8%), A. variegatum (6%), and others. A total of 56 virus isolates were obtained, 26 from A. gemma, 17 from R. pulchellus, 6 from A. variegatum, and 7 from other species. Virus isolates included Dugbe virus (DUGV), an unknown virus related to DUGV, Thogoto, Bhanja, Kadam, Dhori, Barur, and foot-and-mouth disease (FMDV) viruses. This is the first report of Dhori virus isolation in East Africa and the first known isolation of FMDV associated with tick collection. Our results demonstrate the potential for tickborne dissemination of endemic and emergent viruses and the relevance of A. gemma in the maintenance of tickborne viruses in this region.
