Control of important causes of infectious abortion in sheep and goats

This article summarizes control measures for the most common causes of abortion in North America, New Zealand, the United Kingdom, and Europe. When dealing with an abortion outbreak in a flock or herd, diagnostic investigation is critical to assuring that any future control measures are effective and worthwhile. Biosecurity is an important consideration for any abortion control program, and should be promoted regardless of whether an abortion problem exists in the flock. Many of the infectious agents that cause abortion in small ruminants are also zoonotic pathogens, and producers should be educated to avoid risk to themselves and their families.
