Abstract

Since the total of 150,000 doses of attenuated cell culture vaccine doses produced anually in Turkey does not meet the requirements of the country, by reducing the number of vaccine cells in a single dose, an increased number of vaccine doses was obtained for cattle, and doses consisting of different numbers of vaccine cells were tested according to their protective efficiency against tropical theileriosis in cattle. Fifty Holstein calves aged 2.5-3 months were used: 42 of them were used in vaccine dose trials while 8 were used in the determination of pathogenicity of the challenge material.
