  • Title: Development of a highly infective Babesia bigemina vaccine of reduced virulence.
    Author: Dalgliesh RJ, Callow LL, Mellors LT, McGregor W.
    Journal: Aust Vet J; 1981 Jan; 57(1):8-11. PubMed ID: 7236153.
    Abstract:
    The virulence of a strain of Babesia bigemina was reduced by syringe passaging at 3 to 16-week intervals in a series of 7 calves. The calves were splenectomised 1 to 14 weeks after inoculation to induce the relapse parasitaemias used for passaging. Parasites taken at relapse from the last 3 calves in the series were inoculated into splenectomised calves from which highly parasitised blood for vaccine was obtained. The vaccine produced mild infections in 32 recipient cattle. When challenged either 5 weeks or 7 months after vaccination, the cattle had substantial immunity to a heterologous strain of B. bigemina.
