Summary 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.
