RESUMO Prevalência de infecção por tuberculose bovina em gado na prefeitura de Aksu determinada por teste cutâneo tuberculínico (TST) entre 1985 e 2016 foi avaliada. O gado foi analisado de acordo com região, padrão alimentar, rebanho e idade. Um total de 890009 animais foram testados, com prevalência de 0,13% de tuberculose bovina (1172/890009). Diferença estatisticamente significativa foi encontrada em padrão alimentar e rebanhos. Prevalência em vacas (0,19%, 615/327022) foi mais alta que em bois (P< 0,01, OR= 1,903, 95% CI = 1,696 a 2,134). Diferenças significativas (P< 0,01; OR= 2,238, 95%; CI= 1,937 a 2,585) foram evidentes em taxas para tuberculose bovina em casas de camponeses (0,12%, 942/802343) e grupos de fazendeiros (0,26%, 230/87666). A prevalência de bTB caiu na prefeitura Aksu, a taxa positiva se encontrava abaixo de 0.1% a partir de 2010. Conclui-se que as medidas de controle para tuberculose bovina na região de Aksu foram eficazes.

ABSTRACT Prevalence of bovine tuberculosis infection in cattle in Aksu Prefecture determined by intradermal tuberculin skin test (TST), between 1985 and 2016. Cattle were analyzed according to region, feeding pattern, herds and age. A total of 890,009 cattle were tested, with overall bovine tuberculosis prevalence of 0.13% (1172/890009). Statistically significant difference was found in feeding pattern and herds. Prevalence in cows (0.19%, 615/327022) was higher than that in beeves (P< 0.01, OR= 1.903, 95% CI = 1.696 to 2.134). Significant difference (P< 0.01; OR= 2.238, 95%; CI= 1.937 to 2.585) was evident for rates for bovine tuberculosis in the peasant household (0.12%, 942/802343) and farm groups (0.26%, 230/87666). The overall prevalence of bTB was decreased in the Aksu Prefecture, especially the positive rate was under 0.1% in 2010s. We concluded that the control measures forbovine tuberculosis in the Aksu region cattle herds are effective.
