Abstract：The study aimed to understand the prevalence of brucellosis in cattle and sheep in some townships of Yongshan County,Zhaotong City,Yunnan Province.In 2022,a random blood samples was conducted from cattle and sheep in 11 townships of Yongshan County,collecting a total of 6 078 fresh blood samples,including 354 bovine samples and 5 724 sheep samples.The Rose Bengal Plate Agglutination Test was used for the preliminary screening of Brucella antibodies,and the positive samples were confirmed using the cELISA.The results showed that the overall detection rate of brucellosis in cattle and sheep in Yongshan County was 0.05％(3/6 078).Among different sampling areas,the positive rates of brucellosis in cattle and sheep in Makou Town and Huanghua Town were 0.23％(2/872)and 0.25％(1/391),respectively,with no detection in other townships.The difference in brucellosis positive rates among different regions was not significant(P＞0.05).Among different types of livestock,the positive rate of brucellosis in cattle was 0.28％(1/354),and in sheep was 0.03％(2/5 724).The positive rate of brucellosis in cattle was significantly higher than that in sheep(P＜0.05).The results indicate that there are a few positive individuals of brucellosis in some areas of livestock farming in Yongshan County,suggesting that the overall prevention and control work is good,but continued monitoring and active prevention are still needed.
