Isolation of Brucella canis

These strains of Brucella canis were isolated from seropositive dogs: The strains ES 11/78, from a kennel dog, and the strains 215/79 and Pr/79, from stray dogs. The isolates were identified through the morphological, staining and biochemical characteristics (of the agent) as well as serologically, by the use of the isolated strains as antigen against the hyperimmune serum.
