The clinical signs, laboratory findings, diagnosis, epidemiology, treatment, and prevention and control of two emerging causes of placentitis and abortion in horses are described in this article. Leptospirosis has been reported as a significant cause of fetal loss in horses in Kentucky, Northern Ireland, and England. Most abortions result from infection by serovars kennewicki or bratislava. Nocardioform placentitis has become the most common cause of placentitis in central Kentucky horses. Nocardioform placentitis is associated with infection by unnamed, gram-positive, filamentous, branching bacteria, and is characterized by distinctive changes in the placental membranes.
本文描述了马胎盘炎和流产的两种新出现病因的临床症状、实验室检查结果、诊断、流行病学、治疗以及预防和控制方法。在肯塔基州、北爱尔兰和英格兰，钩端螺旋体病已被报道为马胎儿死亡的一个重要原因。大多数流产是由肯尼威克血清型或布拉迪斯拉发血清型感染引起的。诺卡氏菌样胎盘炎已成为肯塔基州中部马匹胎盘炎最常见的病因。诺卡氏菌样胎盘炎与未命名的革兰氏阳性、丝状、分支细菌感染有关，其特征是胎膜有明显变化。
