South Africa has a diverse fauna of ixodid tick species, several of which are of medical or veterinary importance. Elucidation of which host or environmental characteristics determine the composition and abundance of tick assemblages is, therefore, highly relevant to disease management and wildlife conservation efforts. Here, we analysed the similarity in ixodid tick assemblages of three wildlife and three livestock species in a natural (Great Fish River Reserve) and anthropogenic (an adjacent farm) habitat in South Africa. We compared tick infracommunities of three wild host species between the reserve and the farm; of three wild host species within the reserve and of wild and livestock species on the farm (considering body size). Hosts examined in this study harboured the adults and immature stages of 11 tick species belonging to five ixodid genera. Notably, several tick species of South African wildlife have successfully made the switch to livestock and thus both wild hosts and livestock now contribute to the pool of maintenance hosts for these ticks as well as their associated pathogens. This is an important consideration when translocating wildlife or livestock as part of farming or conservation activities.
南非拥有多种壁虱tick 物种,其中有几种具有医学或兽医重要性。因此,阐明哪些宿主或环境特征决定了壁虱组合的组成和丰度,对于疾病管理和野生动物保护工作非常重要。在这里,我们分析了南非自然(大鱼河保护区)和人为(相邻农场)生境中三种野生动物和三种牲畜物种的壁虱组合的相似性。我们比较了保护区和农场中三种野生宿主物种之间的壁虱亚群落;保护区内三种野生宿主物种之间的壁虱亚群落;以及农场中野生动物和牲畜物种之间的壁虱亚群落(考虑体型)。本研究检查的宿主携带了 11 种壁虱物种的成虫和幼虫阶段,这些壁虱物种属于五个壁虱属。值得注意的是,南非野生动物的几种壁虱物种已成功地转移到牲畜身上,因此野生动物和牲畜现在都为这些壁虱及其相关病原体的维持宿主做出了贡献。这是在作为农业或保护活动的一部分转移野生动物或牲畜时需要考虑的重要因素。
