The role of some brucella carriers (stray dogs and rats) in maintenance of brucella infection [electronic resource].

Includes references.

The role of stray dogs and wild rats as brucella carriers as well as their role in spreading and maintenance of brucella infection were investigated. A total of 1640 sheep from different flocks and areas were serologically examined for brucellosis using Rose Bengal and Rivanol tests. At the same time, a total of 182 dogs and 120 rats were collected from both brucella infected and non-infected areas and examined serologically. In addition, tissue sections from their spleens were examined for brucella antigen using the immunoperoxidase technique. Tissue sections from spleens and udders of seropositive ewes were histopathologically examined where different pathological changes could be detected. Brucella antibodies could be detected in sera of 42 ewes as well as 18 dogs and 6 rats that were associated with brucella infected sheep. Brucella antigen could be detected in the spleen of 12 seropositive dogs and 4 rats as well as spleen of 20 ewes.
