Resumo: | Bovine tuberculosis is a zoonosis with worldwide distribution. Its control has a direct impact on public health and livestock production. This study estimated the prevalence of infected herds and adult bovines and evaluated risk factors associated with the presence of tuberculosis within herds in the state of Paraná. The state was divided in seven livestock regions and independent sampling was performed. A total of 1,419 farms were sampled and 16,045 animals were tested using the intradermal comparative cervical tuberculin diagnostic test. The apparent and estimated prevalence rates in farms and adult bovine animals were 2.15% (95% CI: 1.31-3.00) and 0.42% (95% CI: 0.04-0.81), respectively. It was not possible to state with 95% confidence that the disease prevalence in any region was significantly different from that in other regions. There were no positive animals in the western region, and the prevalence of positive herds and animals in the other regions ranged from 1.03% to 3.89% and 0.17% to 1.08%, respectively. The logistic regression model identified larger herd size (OR = 2.4) and mechanical cmilking (OR = 5.18) as risk factors associated with the presence of bovine tuberculosis. The combination of low prevalence with risk factors associated to larger herds and more intensive dairy farming, renders the state of Paraná a good candidate for the implementation of industry-based free-herd accreditation schemes and makes a case for planning risk-based surveillance targeted at major dairy basins. |

Neste trabalho, estimou-se a prevalência aparente de rebanhos e de bovinos adultos infectados, assim como os fatores de risco associados à presença da tuberculose nos rebanhos do estado do Paraná. O estado foi dividido em sete regiões pecuárias para amostragem independente. No total foram amostradas 1.419 propriedades e testados 16.045 animais. A prova diagnóstica utilizada foi a tuberculinização intradérmica cervical comparada. A prevalência aparente em propriedades e em bovinos adultos no estado do Paraná foi estimada em 2,15% [IC 95%: 1,31–3,00] e 0,42% [IC 95%: 0,04–0,81], respectivamente. Em relação às prevalências estimadas por região do estado, foram observadas heterogeneidades, não foi possível afirmar com 95% de confiança que alguma região se destacou das demais em relação à presença da tuberculose bovina. A região Oeste não apresentou animais positivos na amostra e nas demais regiões as prevalências de rebanho e animais variaram entre 1,03% - 3,89% e 0,17% - 1,08%, respectivamente. O modelo de regressão logística múltipla identificou como fatores de risco associados à presença de tuberculose bovina, o aumento do tamanho de rebanho (OR = 2.4) e a existência de ordenha mecanizada na propriedade (OR = 5.18). Assim, os resultados demonstraram que a tuberculose bovina tem prevalência baixa na maioria das regiões do Estado do Paraná e sugerem que o risco da presença da infecção aumenta em rebanhos maiores e nas propriedades leiteiras com maior grau de tecnificação. Estes resultados permitem sugerir que o Paraná está em boas condições para introduzir sistemas de vigilância baseados em risco e para implementar programas de certificação de rebanhos livres, associados às indústrias de laticínios.UEL2016-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2727710.5433/1679-0359.2016v37n5Supl2p3611Semina: Ciências Agrárias; Vol. 37 No. 5Supl2 (2016); 3611-3624Semina: Ciências Agrárias; v. 37 n. 5Supl2 (2016); 3611-36241679-03591676-546Xreponame:Semina.
