Salmonella Abortusovis primarily infects sheep. Infections can cause abortion storms when the organism is newly introduced into a flock; where this organism is endemic, sporadic abortions occur in young and newly introduced animals. Economic losses result mainly from abortions, stillbirths, and illness in lambs infected at birth. Occasionally, ewes develop metritis and septicemia.
