The purpose was to compare the results obtained by ELISA and the following conventional methods used for the diagnosis of bovine brucellosis: Rose Bengal test (RBT), serum agglutination test (SAT) and complement fixation test (CFT). Three different ELISA test kits from various producers were used. The same 362 sera from cattle were examinated by each kit. The sera were represented by: 35 sera positive in RBT, 19 sera coming from naturally infected cattle (received from Great Britain), 3 sera recognized as positive or doubtful in national routine examination and 305 sera negative in RBT. In ELISA, depending on the kit used: 18, 19 and 26 positive and respectively 0.2 and 5 doubtful results were obtained. All remaining sera were negative. A high degree of correlation between ELISA and CFT was obtained. This indicates a high value ELISA diagnosis of bovine brucellosis.
