Ixodes ricinus infesting snakes: Insights on a new tick-host association in a Borrelia burgdorferi sensu lato endemic area.

The castor bean tick Ixodes ricinus is one of the most abundant tick species in Europe, being able to parasitize a wide number of vertebrate hosts, including mammals, birds, and reptiles. This tick species has an important role as vector of zoonotic pathogens, including the causative agents of Lyme borreliosis (i.e. Borrelia burgdorferi sensu lato). Here, we provide insights on a new tick-host association (i.e. I. ricinus infesting snakes) in an area recently recognized as endemic for reptile-associated zoonotic species of Borrelia burgdorferi s.l.
