Resumo: | With the aim of supporting the strategic planning of the National Program for Control and Eradication of Brucellosis and Tuberculosis, different Brazilian states have been conducting cross-sectional studies, coordinated by the Ministry of Agriculture, Livestock, and Supply and with scientific support from the University of São Paulo and the University of Brasilia. In Santa Catarina, the State Animal Health Agency (CIDASC) conducted a study on bovine tuberculosis (TB) prevalence and assessment of risk factors in 2012. The state was divided into five regions and, in each region, independent sampling was performed in two steps: (i) cattle herds with reproductive activity were randomly selected; and (ii) in each herd, a sample of females aged 24 months or older underwent the intradermal comparative tuberculin test. A questionnaire was used to collect data on production characteristics and management practices that could be associated with the tuberculosis infection. Herd prevalence of bovine TB was 0.50% (95% confidence interval [CI]: 0.074–0.93%) while the prevalence of TB in adult females was 0.06% (95% CI: 0–0.12%). No significant difference in the prevalence of infected herds and of positive females was observed among the five regions. The logistic regression model revealed that herds with 19 or more females showed an odds ratio (OR) of 7.68 (95% CI: 1.22–48.39) compared to smaller herds, while dairy herds presented an OR of 10.43 (95% CI: 2.00–54.25) relative to beef or dual-purpose herds. The results suggest that dairy herds, in which animals are kept in partial or total confinement, and larger herds, which tend to acquire animals more often, are at a higher risk of bovine TB. Given the low prevalence and the type of higher-risk properties, a bovine TB surveillance system should be targeted at the state’s dairy basins, particularly the western region that accounts for the major industries and more intensive dairy farms. |

Em Santa Catarina, em 2012, a Companhia Integrada de Desenvolvimento Agrícola (CIDASC) realizou o estudo sobre a prevalência e fatores de risco para da tuberculose bovina (TB). O Estado foi dividido em cinco regiões e, em cada uma delas, foi realizada uma amostragem independente em duas etapas: (i) propriedades com atividade reprodutiva foram selecionadas aleatoriamente; (ii) em cada propriedade, uma amostra de fêmeas com idade igual ou superior a 24 meses foi submetida ao teste tuberculínico intradérmico comparativo. Um questionário foi utilizado para recolher dados sobre as características de produção e práticas de gestão que poderiam estar associados com a infecção tuberculosa. A prevalência de focos de tuberculose bovina foi de 0,50% (95% intervalo de confiança [CI]: 0,074-0,93%), enquanto a prevalência de TB em animais foi de 0,06% (IC 95%: 0-0,12%). Não foi observada diferença significativa na prevalência de focos ou animais entre as cinco regiões. O modelo de regressão logística revelou que rebanhos com 19 ou mais vacas apresentaram um odds ratio (OR) de 7,68 (IC 95%: 1,22-48,39) em comparação com rebanhos menores, enquanto rebanhos leiteiros apresentaram um OR de CI 10,43 (95%: 2.00- 54,25) em relação aos rebanhos de corte ou de duplo propósito. Os resultados sugerem que os rebanhos leiteiros, em que os animais são mantidos em confinamento parcial ou total, e rebanhos maiores, que tendem a adquirir animais mais frequentemente, estão sob maior risco de tuberculose bovina. Dada a baixa prevalência e o tipo de propriedades sob maior risco, um sistema de vigilância para tuberculose bovina deve ser orientados para as bacias leiteiras do Estado, em especial a região oeste, onde encontram-se as principais indústrias e a maioria das explorações leiteiras intensivas.UEL2016-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2728210.5433/1679-0359.2016v37n5Supl2p3659Semina: Ciências Agrárias; Vol. 37 No. 5Supl2 (2016); 3659-3672Semina: Ciências Agrárias; v. 37 n. 5Supl2 (2016); 3659-36721679-03591676-546Xreponame:Semina.
