Ovine Abortion due to Toxoplasmosis

ABORTION of infectious origin in sheep, has been attributed to many organisms. Of the bacterial agents Salmonella abortus ovis and Vibrio fetus appear to be the most common ; of less frequent occurrence are other members of the Salmonella and members of the Brucella, Listerella, Leptospira, Bacteroides and Corynebacterium groups. A virus of the Psittacosis-Lymphogranuloma group has been associated with a large number of flock outbreaks of abortion in Great Britain1 and, more recently, in Germany, France, Hungary and the United States.
