Ixodes ricinus and Borrelia prevalence at the Arctic Circle in Norway
The distribution limit of Ixodes ricinus ticks in northwestern Europe (Brønnøy, Norway, 1◦ south of the Arctic Circle), has been known since the 1930s. To reconfirm this finding and extend studies in the areas adjacent to the Arctic Circle (66◦33 N), ticks were collected from dogs and cats in 8 dist...
