Seroprevalence of Encephalitozoon cuniculi, Francisella tularensis and Toxoplasma gondii in Zoonotic Diseases in European Hares (Lepus europaesus)

Objective:European hares (Lepus europaeus) are among the most important animals that are connected with humans in many countries and natural life. Hares are important for public health, since they carry many zoonotic diseases, such as Encephalitozoon cuniculi, Francisella tularensis and Toxoplasma gondii. The study aimed to determine the seroprevalence of Encephalitozoon cuniculi, Francisella tularensis and T. gondii and the potential zoonotic risk posed by hares that live in provinces of Turkey.Methods:Blood samples were collected from hares during the official hunting season. Serum samples were examined serologically by enzyme-linked immunosorbent assay for E. cuniculi, Sabin-Feldman dye test was used to examine T. gondii, while micro-agglutination test was used to examine F. tularensis.Results:Of the total of 42 hares examined, one (2.4%) was found positive for E. cuniculi, two (4.8%) were found positive for T. gondii and one (2.4%) was found positive for F. tularensis.Conclusion:Anti-T. gondii and anti-E. cuniculi antibodies were serologically detected in hares for the first time in Turkey. Furthermore, this is the first study reporting the seropositivity of F. tularensis infection in hares
