Plasma samples from cattle recovering from acute B. bovis infection contain cryoprecipitable immune complexes (IC). Production of bovine and rabbit antisera to IC and subsequent serological assays indicated IC contained antigens of both babesial and erythrocytic origin. Vaccination of naive cattle...

The optimum gel filtration fraction from lysate of B. bovis infected erythrocytes was determined for use as an antigen in an ELISA to diagnose B. bovis infection in cattle. Of 4 enzyme labels tested, horseradish peroxidase was the most suitable. The assay is both sensitive and specific in detecting ...

The presence of protective antibodies to Babesia bovis has been demonstrated by the passive transfer of immunity with serum from carriers to highly susceptible splenectomized calves. The effector mechanism was mediated by antibodies which reacted with the parasitized erythrocytes and emerging...

A generalized approach to modelling the epidemiology of tick-borne diseases is outlined after reviewing previous approaches to model Babesia spp. Approaches are described for investigating the distribution, abundance and management of such parasites. Geographical distributions can be explored using ...

Experiments were conducted on the induction of immunity to Babesia bovis in cattle with antigen extracted from erythrocytes infected with the parasite. Protection after inoculation with crude parasite-erythrocyte stroma mixtures was as strong as that induced by natural infection. B. bovis appears...

An account is given of living and killed vaccines against bovine babesiosis, with particular reference to Babesia bovis.

Studies undertaken to determine the underlying epidemiological mechanisms that caused endemic babesiosis in areas of Australia infested with Boophilus microplus and to find methods for prediction that would assist babesiosis control are described. It was concluded that the failure of individual...
