Using the indirect fluorescent antibody test, a significant antibody titre to T. parva cell culture schizont antigen was demonstrated until 12-73 weeks (mean 29.7 weeks) after infection in the serum of 35 cattle recovered from experimental East Coast fever. In the same animals a significant titre to T. parva piroplasm antigen was only detected until 7-25 weeks (mean 13.5 weeks) after infection. It is recommended, therefore, that the schizont antigen should be preferred to the piroplasm antigen when the indirect fluorescent antibody test is used in epidemiological studies of East Coast fever.
