Nineteen ewes were injected subcutaneously with the agent of enzootic ovine abortion, Chlamydia psittaci serovar 1, at 50 days gestation. Placental and fetal tissues were examined at 15 days postinfection and thereafter at ten day intervals. Placental infection was detected at 15 days postinfection. Only postinoculation sera collected from postinfected ewes contained antibodies reactive to C. psittaci. Five (26%) chlamydial infected ewes experienced inapparent fetal loss before day 105 of gestation. This finding is significant since C. psittaci infection in sheep is commonly associated with abortion and not infertility.
19只母羊在妊娠50天时皮下注射了地方流行性绵羊流产病原体——鹦鹉热衣原体血清型1。在感染后15天检查胎盘和胎儿组织，此后每隔10天检查一次。感染后15天检测到胎盘感染。仅从感染后的母羊采集的接种后血清中含有对鹦鹉热衣原体有反应的抗体。5只（26%）衣原体感染的母羊在妊娠第105天前发生隐性胎儿丢失。这一发现具有重要意义，因为绵羊感染鹦鹉热衣原体通常与流产而非不育有关。
