Comparison of the indirect enzyme-linked immunosorbent assay (ELISA) with the complement fixation test (CFT) for the serodiagnosis of bovine brucellosis.
Complement fixation and ELISA tests were carried out on 8772 bovine sera. Results showed that ELISA titres were, on average, approximately sixteen times higher than the corresponding C.F. titres. The specificity of ELISA appeared comparable to that of the C.F.T. There was no evidence to show that the ELISA could detect infection earlier than the C.F.T.
