Some aspects of the epidemiology and control of bovine babesiosis in Australia.
A short account of the epidemiology and control of babesiosis in Australia is presented. Epidemiological topics discussed include differences in the transmission of Babesia bovis and B. bigemina by the cattle tick, Boophilus microplus and the relative prevalence, disease incidence and pathogenicity of B. bovis and B. bigemina. Circumstances under which babesiosis occurs in Australia are described. In the Section on control, only vaccination is discussed. Changes in the preparation of babesial vaccines, particularly those resulting in a highly infective vaccine containing relatively avirulent B. bovis are described. Fluctuations in demand, such as the increase from about 100,000 to over 1,000,000 doses in 4 years in the mid-1960s are shown. An unexpected increase in the use of A. centrale in 1973 is discussed, and the supply of B. bigemina for cattle exported from Australia reported.
