RESUMO
Present study was undertaken to determine the association of brucellosis with abortions occurring naturally in sheep at an organized local sheep breeding farm. A total of 15 strains of Brucella melitensis biovar I were isolated from the abortion material. Serologically the aborted ewes were positive for brucellosis by one or more tests. During acute infection (abortion), standard tube agglutination test (SAT) detected more positive reactors (70.7%) while counter immunoelectrophoresis (CIE) detected more positive reactors (33.9%) in chronic infection (in-contact and apparently healthy sheep). Personnel handling the abortion material at the farm were found positive clinically as well as serologically for brucellosis. These observations suggest the zoonotic importance of brucellosis.

Experimental brucellosis with Brucella abortus has been studied in chickens, though antibody response and histopathological changes in the tissues of the birds were conspicuous and noticed consistently, it was not possible to isolate Brucella organisms from lung, liver, spleen and faecal samples of the infected chickens. These observations suggested that birds are resistant to Brucella infection and organisms succumb to death in vivo.
