  • Chemotherapy of experimental Besnoitia besnoiti infection in rabbits 
    Shkap, Varda; De Waal, D.T.; Potgieter, Fred T.; Bigalke, R.D. (Published by The Government Printer, Pretoria, 1985)
    Rabbits were infected with a bovine strain of Besnoitia besnoiti parasites derived from VERO cell cultures. Oxytetracycline*, given at 30 mg/kg i.m. simultaneously with infection, prevented the development of orchitis. The ...
  • An in vivo comparison of the efficacy of the heartwater blood and ground-up tick suspension vaccines in calves 
    Bezuidenhout, J. Dürr; Spickett, Arthur M.; Bigalke, R.D. (Published by The Government Printer, Pretoria, 1985)
    Two groups of calves were respectively immunized with heartwater blood (BV) and ground-up tick suspension (GUTS) vaccine. A third group was left unimmunized as controls. No difference in the immune status conferred could ...
