[Isolation and identification of Clamydia psittaci as the pathogen in enzootic abortion of sheep in eastern Slovakia].
Abortions in ewes occurred on a large scale in three localities in eastern Slovakia. Antibodies to the group-type ornithosis antigen were detected in titres of 1 : 128 to 1 : 2048 in the aborting ewes in the mentioned localities. Suspensions were prepared from the four samples of material, obtained either from the placentae and afterbirths of the aborting ewes or from the tissues of the aborted foetuses. Seven-day old yolk sacs of chicken embryos were infected with these suspensions. Four strains of Chlamydia psittaci were isolated and designated EPO-A2-uterus, EPO-B1 aborted foetus-lung, EPO-B2-aborted foetus-lung, EPO-B3-aborted foetus-spleen. Differential diagnosis eliminated some bacteria, toxoplasma, and parainfluenza-3 virus as possible agents responsible for the abortions.
