By sporadic examination of 492 wild animals and regular weekly checks of dogs (179), cattle (288) and sheep and goats (141), 13 Ixodides were identified in the province of Salamanca. Some of these were only detected on the northern (I. ricinus) or southern (H. lusitanicum and B. annulatus) slopes of the mountains to the south of the province. Except for occasional introductions, H. lusitanicum and B. annulatus are not found on the Castillian plateau. In wild animals, 12 species were found of which only 4 are monotropic for some of these animals. In dogs, the most important species were R. turanicus and R. sanguineus. The latter shows only one generation per year and its nymphs are held to be the most important vector for the cases of boutonneuse fever registered in the provincial setting. In cattle, R. bursa is the most important tick, in terms of its prevalence in June/July (adults) and from November to January (immature forms). It also displays a much higher parasitization intensity than that of any of the other 7 species found on cattle. These remaining tick species (D. marginatus, H. marginatum, H. lusitanicum, I. ricinus, R. turanicus, Hae. punctata and B. annulatus) are abundant when R. bursa is absent; that is, in spring and at the end of summer, which thus are periods of richness in Ixodides but of low parasitism intensity. The ticks found on sheep and goats are the same as those detected on cattle, but in some of them prevalence and intensity vary as result of the kind of pasture frequented by the ovine and caprine hosts.
通过对492只野生动物进行不定期检查，以及对狗（179只）、牛（288头）和绵羊与山羊（141只）进行每周定期检查，在萨拉曼卡省发现了13只蜱虫。其中一些仅在该省南部山脉的北坡（蓖麻硬蜱）或南坡（卢西塔尼亚血蜱和环形牛蜱）被检测到。除偶尔引入外，在卡斯蒂利亚高原未发现卢西塔尼亚血蜱和环形牛蜱。在野生动物中，发现了12个物种，其中只有4种对其中一些动物具有专一性。在狗身上，最重要的物种是图兰扇头蜱和血红扇头蜱。后者每年仅繁殖一代，其若虫被认为是该省记录的纽扣热病例的最重要传播媒介。在牛身上，从6月/7月（成虫）到11月至1月（未成熟形态）的患病率来看，囊形扇头蜱是最重要的蜱虫。它的寄生强度也比在牛身上发现的其他7种蜱虫中的任何一种都要高得多。当囊形扇头蜱不存在时，这些剩余的蜱虫物种（边缘革蜱、边缘血蜱、卢西塔尼亚血蜱、蓖麻硬蜱、图兰扇头蜱、微小牛蜱和环形牛蜱）数量丰富；也就是说，在春季和夏末，因此这些时期是蜱虫丰富但寄生强度较低的时期。在绵羊和山羊身上发现的蜱虫与在牛身上检测到的相同，但其中一些蜱虫的患病率和强度因羊和山羊宿主所光顾的牧场类型而有所不同。
