EVALUATION OF THE ENZYME-LINKED IMMUNOSORBENT ASSAY FOR DETECTING BRUCELLA-ABORTUS ANTIBODIES

Abstract

The specificity of enzyme-linked immunosorbent assays (ELISA) corresponds to conventional methods for detecting Brucella antibodies [Ab] in bovine serum. The ELISA test detected Brucella Ab early in only 12.5% of the cattle sera tested. The sensitivity of ELISA was comparable to complement-fixation and Rivanol methods but less sensitive than the standard tube agglutination method.
