The reproducibility of results in bovine brucellosis serology and their correlation with the isolation of Brucella abortus.
In both the complement fixation test (CFT) and the serum agglutination test (SAT) titres were reproducible for the most part within a twofold range. They seldom exceeded these limits and never a fourfold range. Brucella abortus was successfully isolated in 86% of serologically positive cases and evidence is presented to confirm the use of the 30 International Units/ml level in the CFT as being diagnostically significant. The SAT, when done in microtitration plates, is even more reproducible than when done in tubes. The incidence of infected animals aborting or calving down with negative titres was found to be low.
