What are the symptoms of Chlamydia in sheep?

When chlamydial abortion occurs in a flock, stillborn lambs may be produced one to two weeks before the expected start of lambing although affected ewes may have a vulval discharge and show behavioural changes for up to 48 hours before this. The aborted lamb may look normal or show a degree of subcutaneous oedema.

In flocks infected with Chlamydia psittaci, adding tetracyclines to feed for daily consumption throughout the lambing period may reduce the incidence of abortion.

The route of transmission to humans for C. abortus is uncertain, but direct contact with infected placenta and infective secretions are likely routes. The risk is limited mainly to those actively working with small ruminants, including veterinarians, and their immediate families. Large amounts of C.

Are there any cases of chlamydiosis in sheep?

Chlamydiosis is a highly contagious infection that commonly occurs in sheep flocks of the western U.S. However, because laboratory confirmation of chlamydial abortion can be difficult, the true incidence is not easy to quantify and many infections are not reported.
