The titers of anti-Brucella antibodies in naturally Brucellosis affected unvaccinated cattle, previously vaccinated infected cattle and normal healthy vaccinated cattle were estimated by common agglutination assays MAT, STAT, IHA. The mean antibody titers (log10) were found to be 2.856+0.47 by MAT, 2.041+0.39 by STAT and 2.471+0.51 by IHA, respectively in case of Brucellosis affected cattle which had been vaccinated during calf hood. The mean titers in case of naturally infected cattle which had never been vaccinated were 3.759+ 0.35 by MAT, 3.408+0.32 by STAT and 3.508+ 0.32 by IHA, respectively. The mean titers in healthy unaffected cattle vaccinated during calf hood were as follows 1.401+ 0.31 by MAT, 1.401+0.15 by STAT, and 1.45+0.16 by IHA, respectively. It was interesting to find that the antibody titers in naturally affected cattle which had never been vaccinated previously were very significantly (p<0.01) higher than those of Brucellosis affected cattle which had been vaccinated during calfhood and normal healthy vaccinated cattle unaffected by the disease. The mean titer in Brucellosis affected cattle which had been vaccinated during calfhood was very significantly (p<0.01) higher than that of normal healthy vaccinated cattle unaffected by the disease.
