Molecular survey on the presence of zoonotic arthropod-borne pathogens in wild red deer (Cervus elaphus)

Publication date: August 2016 Source:Comparative Immunology, Microbiology and Infectious Diseases, Volume 47 Author(s): Valentina Virginia Ebani, Guido Rocchigiani, Fabrizio Bertelloni, Simona Nardoni, Alessandro Leoni, Sandro Nicoloso, Francesca Mancianti To estimate the prevalence of some zoonotic tick-borne pathogens in red deer (Cervus elaphus) living in Italian areas with high risk of arthropod exposure, blood samples from 60 red deer were tested by PCR for A. phagocytophilum, Borrelia burgdorferi s.l., Coxiella burnetii, Francisella tularensis, and piroplasms. Thirty-four (56.67%) animals resulted positive for one or more pathogens. In particular, 24 (40%) red deer were positive for A. phagocytophilum, 16 (26.67%) for Babesia divergens, 6 (10%) for C. burnetii, 2 (3.33%) for B. burgdorferi s.l. No positive reaction was observed for F. tularensis. Thirteen (21.67%) animals resulted co-infected by two or three pathogens. Red deer is confirmed as competent reservoir of A. phagocytophilum and B. divergens, but not of B. burgdorferi. This is the first report of C. burnetii-positive red deer in central Italy. Hunters may be at risk of infection both through infected ticks and during the infected cervids carcasses dressing.
