Brucellosis in a dairy herd was controlled by a 5-year vaccination programme with strain 45/20 (dead) B. abortus vaccine, together with gradual elimination of reactors to the rapid plate agglutination test. Non-reactors increased from 37.5% to 96.7% and abortion rate declined from 15.9% to 2.1% in...
