Salmonella enterica subsp. enterica serovar Abortusequi is frequently reported as a cause of abortion in mares and neonatal septicemia and polyarthritis in Asian and African countries, but only sporadically in Europe and the United States. We report an outbreak of S. Abortusequi in foals in Italy, characterized by high mortality. In a herd of Murgese horses, 10 of 34 newborns died at birth and a further 7 died, after developing severe clinical signs, during the first 10 d of life. Tissue specimens from different organs of 2 dead foals, synovial fluids from 4 sick foals, and vaginal and rectal swabs from their dams were cultured. A total of 16 isolates, all as pure cultures, were obtained and identified as Salmonella. The isolates exhibited the same antimicrobial resistance pattern and the same sequence type, ST251, a type that has been associated with S. Abortusequi. Six of 16 isolates were serotyped and found to be S. Abortusequi 4,12:-:e,n,x. Equine practitioners should be aware of S. Abortusequi infection as a cause of neonatal mortality in foals.
肠炎沙门氏菌亚种肠炎血清型马流产沙门氏菌在亚洲和非洲国家常被报道为母马流产、新生驹败血症和多关节炎的病因，但在欧洲和美国仅偶尔出现。我们报告了意大利发生的一起马流产沙门氏菌在驹中的暴发，其特征为高死亡率。在一群穆尔盖赛马中，34匹新生驹中有10匹出生时死亡，另有7匹在出生后的头10天内出现严重临床症状后死亡。对2匹死亡驹不同器官的组织标本、4匹患病驹的滑液以及它们母马的阴道和直肠拭子进行了培养。共获得16株分离菌，均为纯培养物，鉴定为沙门氏菌。这些分离菌表现出相同的抗菌药物耐药模式和相同的序列类型ST251，该类型与马流产沙门氏菌有关。16株分离菌中有6株进行了血清分型，发现为马流产沙门氏菌4,12:-:e,n,x。马医应意识到马流产沙门氏菌感染是驹新生期死亡的一个病因。
