Birds are important hosts in the maintenance and spread of ticks worldwide, including several species of Amblyomma which harbor rickettsial agents as members of the spotted fever group (SFG). The current survey shows the diversity of tick and rickettsial agents infecting ticks on wild birds from an Atlantic rainforest in the state of Bahia, Brazil. A total of 365 birds were captured, representing two orders, 22 families and 51 species, among which 68 specimens (18.6%) were parasitized. Overall, 132 immature ticks (81 larvae and 51 nymphs) were identified to species level, representing six recognized species of the genus Amblyomma: Amblyomma longirostre (n = 45), Amblyomma nodosum (n = 40), Amblyomma varium (n = 5), Amblyomma parkeri (n = 2), Amblyomma coelebs (n = 3) and Amblyomma calcaratum (n = 1). Amplification by PCR and sequencing of rickettsial genes (gltA and ompA), detected the presence of Rickettsia DNA in 12 (9.1%) of the ticks. Rickettsia amblyommatis was the only agent detected in nine larvae and two nymphs of A. longirostre and one nymph of A. varium with 99–100% similarity.

鸟儿在蜱全世界的维护和传播的重要宿主，包括数种花蜱其怀有立克次体代理为一体的斑点热群（SFG）的成员。当前的调查显示，of虫和立克次氏病菌的多样性感染了巴西巴伊亚州大西洋雨林中的野生鸟类的tick虫。总共捕获了365只鸟，代表了两个订单，22个科和51种，其中寄生了68个标本（18.6％）。总体上，132未成熟蜱（81幼虫和51个若虫）被鉴定为物种水平，代表属六个识别物种花蜱：花蜱longirostre（N = 45），花蜱藻（N = 40），花蜱varium（n = 5），Amblyomma parkeri（n = 2），Amblyomma coelebs（n = 3）和Amblyomma calcaratum（n = 1）。通过PCR扩增和立克次体基因（gltA和ompA）的测序，在12个（中（9.1％）检测到立克次体DNA的存在。立克次体是在九个幼虫和两个若虫A. longirostre和一个若虫A. varium中检出的唯一病原，具有99-100％的相似性。
