Abstract

The present study was carried out to evaluate some serological tests for brucellosis based on the rate of Brucella isolation on 140 cows from herds suffering from brucellosis.
Results of bacteriological examination revealed that although some cows whose blood serum was negative or showed 1:10 titres in the agglutination reaction, yet these cows secreted Brucella organisms with their milk.
Correlation between different serodiagnostic tests and the rate of Brucella isolation in this study, were 78.9%, 89.47%, 94.73%, 84.2% for TAT, RBT, Rivanol test, CFT and MRT respec tively.
