Chlamydia psittaci experimental abortion in goats.

To study abortive chlamydiosis in goats, 11 pregnant goats were inoculated intradermally at the 3rd month of pregnancy with 2 X 10(7) or 2 X 10(6) plaque-forming units of a strain of Chlamydia psittaci isolated from naturally occurring abortions in goats. The 11 inoculated does aborted 24 to 56 days after they were inoculated and shed Chlamydia. This shedding began at least 9 days before abortion (1 goat) and persisted 12 days after abortion (1 goat). Retained placenta or metritis were observed in 4 of the goats.
