Attenuation of Babesia bovis by in vitro cultivation. 1987

C E Yunker, and K L Kuttler, and L W Johnson

A virulent strain of Babesia bovis was adapted to grow in erythrocyte culture in the presence of equine serum and in lieu of bovine serum. Four splenectomized calves inoculated with the adapted strain, 429, developed hematologic signs of infection and a low grade fever, but remained free of central nervous system (CNS) signs and recovered. All of six control animals inoculated with a virulent strain reacted severely and five showed CNS signs and died. The calves injected with the attenuated strain were solidly immune when challenged with the virulent strain at 44 or 78 days after vaccination.
