Abstract

Ticks are major vectors of various pathogens of health importance, such as bacteria, viruses and parasites. The problems associated with ticks and vector-borne pathogens are increasing in mountain areas, particularly in connection with global climate change. We collected ticks (n = 2,081) from chamois and mouflon in 4 mountainous areas of France. We identified 6 tick species: Ixodes ricinus, Rhipicephalus bursa, Rh. sanguineus s.l., Haemaphysalis sulcata, H. punctata and Dermacentor marginatus. We observed a strong variation in tick species composition among the study sites, linked in particular to the climate of the sites. We then analysed 791 ticks for DNA of vector-borne pathogens: Babesia/Theileria spp., Borrelia burgdorferi s.l., Anaplasma phagocytophilum, A. marginale, A. ovis, and Rickettsia of the spotted fever group (SFG). Theileria ovis was detected only in Corsica in Rh. bursa. Babesia venatorum (2 sites), Borrelia burgdorferi s.l. (B. afzelii and B. garinii; 2 sites) and Anaplasma phagocytophilum (3 sites) were detected in I. ricinus. Anaplasma ovis was detected at one site in I. ricinus and Rh. sanguineus s.l. SFG Rickettsia were detected at all the study sites: R. monacensis and R. helvetica in I. ricinus at the 3 sites where this tick is present; R. massiliae in Rh. sanguineus s.l. (1 site); and R. hoogstraalii and Candidatus R. barbariae in Rh. bursa in Corsica. These results show that there is a risk of tick-borne diseases for humans and domestic and wild animals frequenting these mountain areas.

从法国 4 个地区的野生山地羚羊和驼鹿身上采集的蜱虫中蜱传病原体的流行情况

蜱虫是细菌、病毒和寄生虫等对健康具有重要意义的各种病原体的主要传播媒介。在山区，与蜱虫和病媒传播的病原体有关的问题越来越多，特别是与全球气候变化有关的问题。我们在法国的 4 个山区收集了羚羊和骡身上的蜱虫（n = 2,081 只）。我们确定了 6 种蜱虫：Ixodes ricinus、Rhipicephalus bursa、Rh. sanguineus s.l.、Haemaphysalis sulcata、H. punctata 和 Dermacentor marginatus。我们观察到，不同研究地点的蜱虫物种组成差异很大，这尤其与研究地点的气候有关。然后，我们对 791 只蜱虫进行了病媒病原体 DNA 分析：这些病原体包括：巴贝西亚/弓形虫属、勃氏波氏杆菌、噬细胞嗜血杆菌、边缘型弓形虫、蜱弓形虫和斑疹热立克次体（SFG）。仅在科西嘉岛的法氏囊中检测到了猫尾丝虫。在蓖麻中检测到了巴贝西亚原虫（2 处）、勃氏波氏杆菌 s.l.（B. afzelii 和 B. garinii；2 处）和噬细胞嗜血杆菌（Anaplasma phagocytophilum；3 处）。所有研究地点都检测到了 SFG 立克次体：在有蓖麻蜱存在的 3 个地点，在蓖麻蜱中检测到了 R. monacensis 和 R. helvetica；在山狗（Rh. sanguineus s.l.）（1 个地点）中检测到了 R. massiliae；在科西嘉岛的布尔萨蜱中检测到了 R. hoogstraalii 和 Candidatus R. barbariae。这些结果表明，经常出入这些山区的人类、家畜和野生动物都有可能感染蜱传疾病。

期刊介绍： Parasite is an international open-access, peer-reviewed, online journal publishing high quality papers on all aspects of human and animal parasitology. Reviews, articles and short notes may be submitted. Fields include, but are not limited to: general, medical and veterinary parasitology; morphology, including ultrastructure; parasite systematics, including entomology, acarology, helminthology and protistology, and molecular analyses; molecular biology and biochemistry; immunology of parasitic diseases; host-parasite relationships; ecology and life history of parasites; epidemiology; therapeutics; new diagnostic tools. All papers in Parasite are published in English. Manuscripts should have a broad interest and must not have been published or submitted elsewhere. No limit is imposed on the length of manuscripts, but they should be concisely written. Papers of limited interest such as case reports, epidemiological studies in punctual areas, isolated new geographical records, and systematic descriptions of single species will generally not be accepted, but might be considered if the authors succeed in demonstrating their interest.
