2002年1月至2004年12月，在葡萄牙大陆圣安德烈自然保护区和孟山都森林公园发现的40只野生鸟类中，共采集到152只扁虱。从22种鸟类中鉴定出5种硬蜱，并对部分种类提供了寄主新记录。此外，用聚合酶链式反应对32只(21%)的硬蜱进行了检测，检测的病原体属于立克次体：吞噬细胞无浆菌、查菲埃立克体病和立克次体。5份样本(15.6%)获得了扩增产物。在边缘透明线虫、腹形硬蜱和图兰氏立克次体中分别发现了与伊氏立克次体、赫氏立克次体和马氏立克次体相似的GLTA序列的立克次体DNA。这是葡萄牙首次报告从野鸟身上采集的壁虱感染立克次体。鉴于上述结果，野生鸟类在维持和传播几个壁虱物种和相关立克次体方面发挥了重要作用。
From January 2002 to December 2004, 152 ticks were collected from 40 wild birds recovered in Santo Andre Natural Reserve and Monsanto Forestal Park, Portugal mainland. Five ticks species were identified from 22 species of birds, and new host record were provided for some species. In addition, 32 (21%) ticks were screened by PCR to detect infections with agents belonging to order Rickettsiales: Anaplasma phagocytophilum, Ehrlichia chaffeensis, and Rickettsia spp. PCR amplicons were obtained in 5 (15.6%) tick samples. Rickettsia DNA exhibiting gltA sequences similar to those of Rickettsia aeschilimannii, R. helvetica and R. massiliae were identified in Hyalomma marginatum, Ixodes ventalloi and in Rhipicephalus turanicus, respectively. This is the first report of rickettsiae infections in ticks collected from wild birds in Portugal. Giving the results presented above wild birds play an important role in the maintenance and dissemination of several tick species and associated rickettsiae.
