The disease in cattle, water buffalo, and bison is caused almost exclusively by Brucella abortus; however, B suis occasionally is isolated from seropositive cows but does not appear to cause clinical signs and is not contagious from cow to cow.

Infection spreads rapidly and causes many abortions in unvaccinated cattle. In a herd in which disease is endemic, an infected cow typically aborts only once after exposure; subsequent gestations and lactations appear normal.

Diagnosis is based on bacteriology or serology. B abortus can be recovered from the placenta but more conveniently in pure culture from the stomach and lungs of an aborted fetus. Most cows cease shedding organisms from the genital tract when uterine involution is complete. Foci of infection remain in some parts of the reticuloendothelial system, es...
