Detection of Rickettsia helveticain Ixodes ricinusticks collected from Pyrenean chamois in France

Seventy-one Ixodes ricinusticks collected from Pyrenean chamois (Rupicapra pyrenaica) in the French Pyrenees were tested by real-time polymerase chain reaction to detect the presence of Rickettsiaand Bartonella. Four ticks (6%) were positive for R. helvetica. The chamois carries infected ticks, and this enables the dissemination throughout the environment with this bacterium, a potential human pathogen.
