ABSTRACT Ilha Grande, Rio de Janeiro State, is an important island remnant of Atlantic Forest and presents four conservation units. Although dogs are forbidden inside conservation units, in Ilha Grande they are present in all villages, many of them are bred loose, interacting with the tourists, the surrounding forest, and the wild animals. The entry of dogs into forests and encounters with wild animals can promote the exchange of parasites such as ticks and their associated pathogens. We sought to survey the tick fauna of dogs and verify whether host-related factors, as well as localities, and street access are associated with the presence of ticks. We sampled 11 villages, totalling 388 dogs. Ticks were collected off 118 dogs. The most prevalent tick was Rhipicephalus sanguineus sensu lato accounting for 28.87% of tick individuals. Amblyomma ovale and Amblyomma dubitatum were present on seven and one dog, respectively. Dogs with street access, bad body condition, medium and large size, and without defined breed showed a higher occurrence of R. sanguineus s.l. Although we observed dogs on trails, within the forest, and the owners themselves indicated a strong relationship of dogs with the forest, we found a low prevalence of ticks associated with wild animals.

巴西里约热内卢州格兰德岛影响犬蜱发生的宿主相关因素

摘要里约热内卢州的格兰德岛是大西洋森林的重要岛屿遗迹，拥有四个保护单位。虽然在保护单位内禁止养狗，但在格兰德岛，它们存在于所有村庄，其中许多是松散饲养的，与游客、周围的森林和野生动物互动。狗进入森林和与野生动物接触会促进蜱等寄生虫及其相关病原体的交流。我们试图调查狗的蜱动物群，并验证宿主相关因素、地点和街道通道是否与蜱的存在有关。我们采样了 11 个村庄，总共 388 只狗。从 118 只狗身上收集蜱虫。最流行的蜱是Rhipicephalus sanguineus sensu lato，占蜱个体的28.87%。分别在 7 只和 1 只狗身上出现了 Amblyomma ovale 和 Amblyomma dubitatum。有街道通道、身体状况不佳、中型和大型且没有明确品种的狗显示出较高的血红血丝 sl 虽然我们在小径上观察过狗，但在森林内，主人自己表明狗与在森林中，我们发现与野生动物相关的蜱的流行率很低。
