This study investigates the presence, identity and infestation prevalence of ticks in different steppe bird species in central Spain, as well as the potential influence of anthropogenic practices, such as grazing, in this regard. In addition, the presence of vector-borne pathogens and the presence of avian malaria in ticks of different bird species is determined using molecular techniques. On the other hand, the variation in prevalence of both ticks and avian malaria is analyzed according to the species of birds and the livestock density in the study area. The prevalence of tick infestation ranged from 1.7% in the Western Black-eared Wheatear (<i>Oenanthe hispanica</i>) to 46.3% in the Dupont’s Lark (<i>Chersophilus</i> <i>duponti</i>), being significantly higher in the Dupont’s Lark. The presence of ticks with avian malaria was found in two of the species analyzed. The percentage of ticks in which avian malaria was detected was 100% for Western Black-eared Wheatear (two ticks analyzed) and 21.6% for the Dupont’s Lark (of the 409 ticks analyzed). The presence of ticks and prevalence of avian malaria was not significantly related to the intensity of livestock density. Our results provide new and relevant information on the probability of tick infestation in steppe birds and their potential role as a vector of infectious diseases.
本研究针对西班牙中部不同草原鸟类宿主的蜱虫存在情况、物种组成及侵染率展开调查,同时探讨放牧等人为活动对此的潜在影响。此外,本研究借助分子技术检测了不同鸟类宿主蜱虫体内的媒介传播病原体与禽疟原虫感染状况。另一方面,本研究依据研究区域内的鸟类物种与牲畜密度,分析了蜱虫侵染率与禽疟感染率的变化差异。研究结果显示,蜱虫侵染率范围为西黑耳䳭(Oenanthe hispanica)的1.7%至杜氏百灵(Chersophilus duponti)的46.3%,其中杜氏百灵的蜱虫侵染率显著更高。在本次分析的鸟类物种中,共有2个物种的蜱虫检出禽疟原虫感染:西黑耳䳭的2只检测蜱虫样本的禽疟原虫检出率为100%,杜氏百灵的409只检测蜱虫样本的禽疟原虫检出率为21.6%。蜱虫侵染与禽疟感染率均与区域牲畜密度无显著相关性。本研究结果为草原鸟类蜱虫侵染风险及其作为传染病传播媒介的潜在作用提供了全新且具有重要参考价值的科学信息。
