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.
斯洛伐克东部三个地区的母羊发生了大规模流产。在所提及地区流产的母羊中，检测到针对群型鸟疫抗原的抗体，效价为1:128至1:2048。从四个样本材料制备了悬液，这些材料要么取自流产母羊的胎盘和胎衣，要么取自流产胎儿的组织。用这些悬液感染7日龄鸡胚的卵黄囊。分离出四株鹦鹉热衣原体，分别命名为EPO - A2 -子宫、EPO - B1 -流产胎儿 - 肺、EPO - B2 -流产胎儿 - 肺、EPO - B3 -流产胎儿 - 脾。鉴别诊断排除了一些细菌、弓形虫和副流感3病毒作为可能导致流产的病原体。
