An abortion outbreak occurred in a herd of 38 horses, 26 of which were pregnant mares. Twenty-one mares aborted between 5-10 months of gestation. In no case were there indications of impending abortion. Pathoanatomical, histopathological, virological and bacteriological examinations were carried out on 4 aborted fetuses. Histopathology identified Gram-negative bacteria compatible with salmonella in all 4 placentae. By subsequent bacteriological examination Salmonella abortusequi was isolated as the single causative agent in each case. Nonmotile Salmonella abortusequi with antigenic formula 4,12:-:- was isolated from one of the 4 fetuses. The described episode of equine abortion clearly indicates that Salmonella abortusequi has not been eradicated from Europe as previously thought.
在一群38匹马中发生了一次流产疫情，其中26匹是怀孕母马。21匹母马在妊娠5至10个月期间流产。在任何情况下都没有即将流产的迹象。对4个流产胎儿进行了病理解剖、组织病理学、病毒学和细菌学检查。组织病理学在所有4个胎盘标本中均鉴定出与沙门氏菌相符的革兰氏阴性菌。通过随后的细菌学检查，在每个病例中均分离出马流产沙门氏菌作为唯一病原体。从4个胎儿中的1个分离出抗原型为4,12:-:-的无动力马流产沙门氏菌。所描述的马流产事件清楚地表明，马流产沙门氏菌在欧洲并未如之前所认为的那样被根除。
