Abstract

Abstract There is a knowledge gap in the study of Argasidae soft ticks and the pathogens they can transmit. These hematophagous arthropods are widely distributed and are often considered typical bird ectoparasites. Tick-parasitized birds can act not only as a reservoir of pathogens but also can carry these pathogen-infected arthropods to new areas. Seven griffon vulture nestlings were sampled in northeastern Spain, collecting ticks ( n = 28) from two individuals and blood from each vulture ( n = 7). Blood samples from griffon vultures tested PCR positive for Flavivirus (7/7), Anaplasma (6/7), piroplasms (4/7), and Rickettsia (1/7). A total of 27 of the 28 analyzed ticks were positive for Rickettsia , 9/28 for Anaplasma , 2/28 for piroplasms, and 5/28 for Crimean-Congo Hemorrhagic fever virus (CCHFv). Sequencing and phylogenetic analyses confirmed the presence of Rickettsia spp., Babesia ardeae , and zoonotic Anaplasma phagocytophilum in vultures and Rickettsia spp., B. ardeae , and CCHFv genotype V in ticks.

比利牛斯狮鹫雏鸟中与蜱虫、传播病原体和血液寄生虫相关的健康风险

摘要对软蜱及其传播病原体的研究还存在空白。这些食血节肢动物分布广泛，通常被认为是典型的鸟类外寄生虫。被蜱寄生的鸟类不仅可以作为病原体的储存库，而且可以携带这些感染病原体的节肢动物到新的地区。在西班牙东北部采集了7只秃鹫雏鸟，从2只秃鹫身上采集蜱虫(n = 28)和每只秃鹫的血液(n = 7)。从秃鹫的血液中检测到黄病毒(7/7)、无原体(6/7)、弓形虫(4/7)和立克次体(1/7)的PCR阳性。分析的28只蜱中，27只立克次体呈阳性，9只无原体呈阳性，2只弓形体呈阳性，5只克里米亚-刚果出血热病毒呈阳性。测序和系统发育分析证实，秃鹫中存在立克次体、阿氏巴贝斯虫和人畜共患吞噬细胞无形体，蜱中存在立克次体、阿氏巴贝斯虫和CCHFv基因型。

期刊介绍： European Journal of Wildlife Research focuses on all aspects of wildlife biology. Main areas are: applied wildlife ecology; diseases affecting wildlife population dynamics, conservation, economy or public health; ecotoxicology; management for conservation, hunting or pest control; population genetics; and the sustainable use of wildlife as a natural resource. Contributions to socio-cultural aspects of human-wildlife relationships and to the history and sociology of hunting will also be considered.
