Enzootic abortion of ewes (EAE) is caused by a bacteria Chlamydophila abortus  (Chlamydia psittacci). It is a zoonotic disease that affects humans, birds, sheep, goats and cattle.


How is it transmitted?   Exposure to the birthing fluids and placentas of aborting animals. Drying of the aborted fetus birthing fluids can result in inhalation of the organism.  Ewes rarely abort a second time but remain persistently infected and can shed the organism during their estrus cycles.

birthing fluids
Transmission occurs upon exposure to infected birthing fluids

Signs in animals? C. abortus causes chronic infection of the reproductive tract, abortion and retained placetas in ewes. Vaginal discharges may be suggestive of abortion.
