History Reported for the first time in 1959 in Germany, then diagnosis of the disease occurred in Bulgaria, Spain, USA, France, India, Japan, United Kingdom, Chad, Greece, and Tunisia. In many areas it is the second cause of abortions, and in areas where Brucellosis is controlled it is the number one cause of infectious abortions. It is seen mostly in ewes, but can have an effect on goat farms also.

Cause of Chlamydial Abortions It is caused by a bacteria known as Chlamydia psittaci . This organism will spread through infected fetuses, placentas, vaginal discharges, feces and nasal secretions. The organism enters the bloodstream but causes no signs of infection in the ewe unless she is, or becomes, pregnant. During pregnancy, the organism enters the uterus and causes inflammation of the placenta and death of the fetus. If infection occurs before conception, the ewe will abort during midpregnancy. If infection occurs during early pregnancy, abortion will occur 60 to 90 days thereafter. If infection occurs during mid or late pregnancy, stillbirths and weak lambs at birth may result.
