Abstract

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...

Abstract

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 ...

Abstract

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...

Abstract

In studies in Australia, Babesia bovis that had recently been exposed to gamma -radiation or had been re-isolated from cattle infected 12 months previously with irradiated parasites were not transmitted transovarially by Boophilus microplus (Can.), though the parent strain of the pathogen that had...

Abstract

Two groups (groups 2 and 3) of susceptible two-year-old non-splenectomized Hereford cattle and a group (group 1) of splenectomized three-month-old calves of mixed breeds were infected with a virulent Babesia bovis strain. All non-splenectomized cattle were severely affected, and one of six animals...

Abstract

The haemolytic activity of serum complement was measured in cattle during B. bovis infection. It fell significantly on the 5th day after infection and was not detectable by the 10th day. After clinical recovery between 15 and 20 days after infection it was again detected in serum and gradually...

Abstract

Serum carboxypeptidase B (SCPB) levels were measured in splenectomized calves and in non-splenectomized cattle infected with three virulent and one avirulent strains of B. bovis, and in splenectomized calves infected with virulent B. bigemina. SCPB levels began falling three days after infection in ...

Abstract

Five splenectomised calves were immunised with a soluble extract prepared from erythrocytes infected with B. bovis and then challenged by the intravenous inoculation of virulent B. bovis along with appropriate control animals. All controls died but 4 of the 5 immunised animals survived. All...

Abstract

The abnormal plasma proteins, produced during Babesia bovis infection in cattle, which form gels with protamine sulphate and ethanols were characterized. Their sizes and chain structures suggest they are intermediates in the conversion of fibrinogen to cross-linked fibrin. In addition, comparison...
