This study aims to investigate the infection status and epidemiological distribution of Salmonella abortus equi in Nilka County,Ili Kazakh Autonomous Prefecture,Xinjiang.Using a Salmonella abortus equi antibody ELISA detection kit,antigen and antibody testing and a survey were conducted on 120 mare serum samples randomly collected in 2025 from five major townships(Nikla Town,Musi Town,Karasu Township,Subutai Township,and Kokhotohor Mongol Township)in Nilka County,Ili Kazakh Autonomous Prefecture.The results showed that the overall seroprevalence of Salmonella abortus equi in Nilka County was 9.17%(11/120).The positive rate varied among townships,with Musi Town having the highest rate at 12.00%(3/25)and Kokhotohor Mongol Township the lowest at 5.00%(1/20).Among the sampled mares,the positive rate for Salmonella abortus equi was 14.63%(6/41)in primiparous mares and 6.33%(5/79)in pluriparous mares;The positive rate was 10.00%(7/70)in intensive farming operations and 8.00%(4/50)in backyard farming operations.This study indicates that Salmonella abortus equi infection has been well prevented in Nilka County due to the attention of the local government,but it still occurs sporadically.It remains one of the main causes of abortion in pregnant mares in the region,posing a continuous threat to the healthy development of the local horse industry.
