RESUMO
OBJECTIVE@#To determine the exposure of wild brown hares [Lepus europaeus (L. europaeus), pallas] to Anaplasma phagocytophilum (A. phagocytophilum), Borrelia burgdorferi (B. burgdorferi) sensu lato, Encephalitozoon cuniculi (E. cuniculi), Leishmania sp., Neospora caninum (N. caninum) and Toxoplasma gondii (T. gondii).@*METHODS@#Two hundred twenty-two blood serum samples of wild brown hares captured in protected areas of the province of Pisa (Central Italy) were tested to detect antibodies against the reported pathogens.@*RESULTS@#Thirty one (14.0%) animals resulted positive for at least one tested agent, with antibody titres ranging from 1:20 to 1:320. In particular, 13 (5.8%) samples were positive to B. burgdorferi s.l., 11 (4.9%) to N. caninum, 3 (1.3%) to T. gondii, 2 (0.9%) to A. phagocytophilum and 2 (0.9%) to Leishmania sp. No samples scored positive to E. cuniculi. Four animals (14.8%) resulted coinfected with 2 different pathogens.@*CONCLUSION@#The obtained results showed that B. burgdorferi s.l. N. caninum, T. gondii, A. phagocytophilum and Leishmania sp. circulate in wild brown hares in Central Italy, suggesting a possible role of L. europaeus as reservoir of these pathogens. The obtained results showed that autochthonous wild brown hares living in Central Italy have been exposed to several pathogens circulating in this area, suggesting a possible role of L. europaeus as reservoir.

Methods Two hundred twenty-two blood serum samples of wild brown hares captured in protected areas of the province of Pisa (Central Italy) were tested to detect antibodies against the reported pathogens.

RESUMO
Objective: To determine the prevalence of vector-borne bacteria and protozoa in hunting dogs living in Central Italy. Methods: Molecular testing was executed on DNA which was extracted from blood specimens collected from 117 asymptomatic dogs to detect Anaplasma phagocytophilum, Babesia canis (B. canis), Bartonella spp., Coxiella burnetii (C. burnetii), Ehrlichia canis, Hepatozoon canis, and Leishmania infantum. Results: A total of 48 dogs (41.0%) were infested by Ixodes ricinus and Rhipicephalus sanguineus ticks. Tick-borne infections were observed in 64 (54.7%) animals. More in detail, 38 dogs (32.5%) screened positive for Hepatozoon canis, 24 (20.5%) for Bartonella vinsonii subsp. berkhoffii, 20 (17.1%) for Leishmania infantum, 6 (5.1%) for C. burnetii, 5 (4.3%) for B. canis (3 B. canis vogeli and 2 B. canis canis), 3 (2.5%) for Anaplasma phagocytophilum, and 2 (1.7%) for Ehrlichia canis. Mixed infection by 2 agents occurred in 17 (14.5%) subjects, by 3 agents in 7 (6.0%) dogs, and by 4 agents in 1 (0.9%) animal. Conclusions: The results demonstrated that several vector-borne pathogens were circulating in this region and dogs infected by these agents were usually asymptomatic. A relevant finding was the presence of DNA of C. burnetii, a severe zoonotic agent, in the 5.1% of tested dogs, which can be source of infection for their owners not only through tick bites, but also directly with urine, feces and birth products.
