Brucella abortus in the bitch: subclinical infection associated with urinary excretion

Brucella abortus infection in the bitch, associated with an aborted bovine fetus, is described. Clinical signs were absent, but the organism was isolated from many sites in the body, including the urine, after death. The response of the dog to B. abortus infection and its possible role as a vector of the disease is discussed.
