Abstract
One group of 28,714 bovine sera were tested by both the brucellosis tube serum agglutination test and the brucellosis card test. The tube serum agglutination test confirmed 99.8% of the negative brucellosis card test results. The brucellosis card test identified 63% of the tube serum agglutination test reactors. In a second group of 496 sera reacting to either the tube serum agglutination test, complement fixation test, plate serum agglutination test or acid antigen serum agglutination test the brucellosis card test identified 99.1% of the complement fixation test positive sera and 91.3% of the sera reacting to any of the other serological tests. The brucellosis card test showed satisfactory agreement with both the complement fixation test and tube serum agglutination test. It appears to be a useful screening test in operations involving large numbers of animals since under these conditions the reactors can be quickly identified and isolated.
