Abstract: Coxiella burnetii, the etiological agent of human Q fever, can infect mammals, birds, and arthropods. The Canary Islands (Spain) are considered an endemic territory, with a high prevalence in both humans and livestock. Nonetheless, there is no epidemiological information about the wild and peridomestic cycles of C. burnetii. Tissue samples from rodents on farms (100) and wild rabbits (129) were collected and assessed by PCR to detect C. burnetii DNA. In parallel, ticks were also collected from vegetation (1169), livestock (335), domestic dogs (169), and wild animals (65). Globally, eight rodents (8%) and two rabbits (1.5%) were found to be positive, with the spleen being the most affected organ. Tick species identified were Hyalomma lusitanicum, Rhipicephalus turanicus, Rhipicephalus sanguineus, and Rhipicephalus pusillus. Hyalomma lusitanicum (80%) was the main species identified in vegetation, livestock, and wild animals, whereas Rhipicephalus sanguineus was the most prevalent in domestic dogs. Overall, C. burnetii DNA was detected in 6.1% of the processed ticks, distributed between those removed from livestock (11.3%), domestic dogs (6.9%), and from wild animals (6%). Ticks from vegetation were all negative. Results suggest that, in the Canary Islands, C. burnetii develops in a peridomestic rather than a wild cycle.
