近5年白云鄂博矿区牛羊布鲁氏菌病 流行状况分析.

In order to understand the recent epidemic status of brucellosis in cattle and sheep (referred to as brucellosis) in Baiyun Obo mining area, and provide references for the prevention and control of brucellosis in livestock, the tiger red plate agglutination test (RBPT) method was used to detect the serum of cattle and sheep in Baiyun Obo mining area from 2018 to 2022 to analyze the prevalence of brucellosis. The results showed that from 2018 to 2022, a total of 38 farmers and 5435 serum samples were tested, and 25 (sheep) positive serum were tested, with an average individual positive rate of 1.83%. Among them, there were three positive farmers, and the average positive rate of farmers was 5.36%. The positive rates of (sheep) individuals in each year were 0, 0, 1.12%, 0.71% and 0. The positive rates of farmers were 0, 0, 16.67%, 9.09% and 0. The positive rates of 2018 and 2019 were 0, which suddenly increased in 2020 and followed by a downward trend. According to the statistics of different livestock species, the average individual positive rate of cattle and sheep was 0 and 0.36%, respectively. The results found that the incidence of brucellosis in Baiyun Obo mining area from 2018 to 2022 was at a low level, and the average individual positive rate was only 1.83%, indicating that the prevention, control and purification of brucellosis in the whole region had a significant effect. The study also found that the incidence of brucellosis in female animals was higher than that of male animals, and the onset of brucellosis was mostly from July to August, which was different from the common time distribution of brucellosis.
