Resumo: | A cross sectional study was carried out between May and November 2011 to investigate the epidemiological situation of bovine tuberculosis (bTB) in the state of São Paulo, Brazil. The state was divided into seven regions. Three hundred farms from each region, with reproductive activity, were randomly chosen and included as primary sample units. A fixed number of bovine females, older than 2 years of age, were randomly selected and tested, using the comparative cervical tuberculin test. An epidemiological questionnaire based survey was conducted in the selected farms. Our results show that in the state of São Paulo, the apparent prevalence of positive farms was 9% (95% confidence interval, 95% CI = 7.8 – 10.5%). The prevalence in the individual regions varied between 3.5% (95% CI = 1.7 ? 6.8%) and 13.9% (95% CI = 10.2 – 18.8%). The apparent prevalence of positive animals in the state was 1.3% (95% CI = 0.9 – 1.7%) and varied from 0.3% (95% CI = 0.2 – 0.6%) to 2.5% (95% CI = 1.4 – 4.5%) in the regions. The risk factors associated with tuberculosis in the state were (i) number of adult females in a herd is ? 24 (Odds ratio, OR = 1.91, 95% CI = 1.32 – 2.75), (ii) type of farm enterprise (dairy: OR = 2.70, 95% CI = 1.40 – 5.21; mixed: OR = 2.03, 95% CI = 1.08 – 3.82), (iii) milking process (milking parlor: OR = 4.12, 95% CI = 1.46 – 11.64; portable milking machine: OR = 2.94, 95% CI = 1.42 – 6.09), and (iv) pasture sharing (OR = 1.58, 95% CI = 1.07 – 2.33). The state of São Paulo should implement a structured surveillance system to detect and mitigate the disease. Further, an efficient animal health education program, which encourages the farmers to test replacement animals for bTB prior to introduction in their herds and to avoid pasture sharing with farms of unknown sanitary conditions should also be implemented. |

O estado foi dividido em sete regiões. Trezentas propriedades com atividade reprodutiva de bovinos de cada região foram aleatoriamente selecionadas e consideradas unidades primárias de amostragem. Um número fixo de fêmeas bovinas com idade superior a dois anos foram aleatoriamente selecionadas e testadas usando o teste cervical comparativo. Um inquérito epidemiológico, utilizando um questionário específico, foi realizado em cada propriedade selecionada. Os nossos resultados indicam que no estado de São Paulo, a prevalência aparente de propriedades positiva foi de 9% (intervalo de confiança de 95%, IC95% = 7,8 – 10,5%). A prevalência nas diferentes regiões variou entre 3,5% (IC95% = 1,7 – 6,8%) e 13,9% (IC95% = 10,2 – 18,8%). A prevalência aparente de animais positivos no estado foi 1,3% (IC95% = 0,9 – 1,7%) e variou de 0,3% (IC95% = 0,2 – 0,6%) até 2,5% (IC95% = 1,4 – 4,5%) nas regiões. Os fatores de risco associados à tuberculose no estado foram (i) número de fêmeas adultas nos rebanhos ? 24 (Odds ratio, OR = 1,91, IC95% = 1,32 – 2,75), (ii) tipo de exploração (leite: OR = 2,70, IC95% = 1,4 – 5,21), misto: OR = 2,03, IC95% = 1,08 – 3,82), (iii) tipo de lactação (sala de ordenha: OR = 4,12, IC95% = 1,46 – 11,64; ordenha mecânica: OR = 2,94, IC95% = 1,42 – 6,09) e (iv) compartilhamento de pastagens (OR = 1,58, IC95% = 1,07 – 2,33). O estado de São Paulo deve implementar um sistema de vigilância estruturado capaz de detectar e mitigar a doença. Além disso, um programa de educação em saúde animal eficiente, capaz de encorajar os proprietários a testar animais de reposição para bTB previamente à introdução no rebanho e evitar o compartilhamento de pastagens com propriedades cuja condição sanitária é desconhecida, deve ser implementado.UEL2016-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2728310.5433/1679-0359.2016v37n5Supl2p3673Semina: Ciências Agrárias; Vol. 37 No. 5Supl2 (2016); 3673-3684Semina: Ciências Agrárias; v. 37 n. 5Supl2 (2016); 3673-36841679-03591676-546Xreponame:Semina.
