[Prevalence of tropical theileriosis in cattle in the Aydin Region and determination of efficacy of attenuated Theileria annulata vaccine].
The present study was carried out to find out the prevalence of tropical theileriosis in the Aydin region and to determine immune status of cattle vaccinated with Theileria annulata schizont vaccine using the indirect fluorescence antibody test (IFAT) during and after the disease season. A total of 236 out of 466 cattle found to be seronegative with IFAT were vaccinated in the Aydin region (Cine, Incirliova, Nazilli, and Centrum) before the disease season (March). The remaining cattle (230/466) served as controls. Blood samples were collected from all cattle following the vaccination once in each month of April, June, September, and December (a total of 4 times) to determine the incidence of the disease using microscopic and serologic evaluations. Results indicated that the incidence of the disease varied among the regions. Clinical theileriosis was found in a total of 22 cattle (10 vaccinated, 12 unvaccinated) during the disease season.
