Abstract:To evaluate the effectiveness of brucellosis prevention and eradication measures in livestock within Dejiang county,omprehensive monitoring activities were conducted from 2022 to 2024.A total of 198 pig,cow,and sheep farming households were tested,with serum samples collected including 3 423 from pigs,5 972 from sheep,12 071 from cattle,and 1 609 from dairy cows..The initial screening was performed using the Rose Bengal Plate Agglutination Test(RBPT),followed by confirmatory testing with the Competitive Enzyme-Linked Immunosorbent Assay(cELISA).The results showed that,over the period of 2022 to 2024,a total of 1 positive cattle herd and 6 positive samples were detected according to the distribution of animal herds.Pigs,sheep,and cows were all negative;Specifically,in 2022,a total of 5 070 samples were tested with no positive results;in 2023,out of 8 891 samples tested,there were still no positive findings;whereas in 2024,among 9 114 samples tested,six positive cases were identified,representing a positivity rate of 0.065%,all from cattle herds,None of the pigs,goats,or dairy cow populations showed any signs of brucellosis infection.The results indicate that the outbreak of brucellosis among livestock in Dejiang county has been effectively controlled,reaching stable control standards and effectively preventing the risk of brucellosis among livestock.However,the risk of disease transmission remains,and further monitoring and prevention efforts are needed to accelerate the purification of brucellosis.This study provides data support for the prevention and control of brucellosis in the future.
