Comparison of agar gel precipitation and complement fixation test for the detection of Brucella ovis infection.

Blood samples from 710 sheep raised in 20 different farms were examined for Brucella ovis antibodies. Thirty samples were positive with complement fixation, 35 samples with precipitation, and 58 samples with both tests. It has been concluded that the gel precipitation technique is adequate for screening but for individual testing both methods should be used simultaneously.
