title: Comparison of serological tests for Brucella melitensis infection in sheep.
abstract: A comparative study of the standard tube agglutination test (SAT), Rose Bengal plate agglutination test and counter immuno-electrophoresis (CIEP) was made on 647 sera from naturally aborting ewes, orchitic, in-contact and apparently healthy sheep with no history of vaccination against brucellosis. No individual test could detect all the 13 known positive reactors (the foetuses of which yielded Brucella melitensis) but by combination of two tests all 13 were positive. The SAT detected more reactors during the early stage of infection while CIEP performed better in later stages of infection. All these tests may be carried out in a field laboratory at very low cost.
