Spatial and temporal analyses of culls due to bovine tuberculosis in slaughterhouses of Minas Gerais state, Brazil, 2008 to 2012

ABSTRACT: The application of spatial and temporal analysis in epidemiology aims to understand the causes consequences heterogeneity studies infectious diseases. Bovine tuberculosis (bTB) is a chronic progressive disease caused by Mycobacterium bovis an important zoonosis worldwide. aim this study was conduct analyses secondary database bTB-positive cases registered Federal Inspection Service two slaughterhouses from West Minas mesoregion Gerais state, Brazil, 2008 2012 suggest its use epidemiological surveillance. culled cattle with bTB macroscopic lesions during post mortem inspection were considered positive study. data used on “Sistema de Informações Gerenciais do Serviço Inspeção Federal” (SIG/SIF - Management Information System Service) “Ministério da Agricultura, Pecuária e Abastecimento” (MAPA Ministry Agriculture, Livestock Supplies), number animals slaughtered monthly their municipalities origin, per slaughterhouse. prevalence (%) calculated, relationship between these human (hTB) GDP capita mesoregions comprising surveyed evaluated. 1,030 (0.28%). lowest case numbers rates obtained 2010, while highest observed 2011. Slaughterhouse 1 showed stationarity, 2 increasing annual trend for since October 2009. A statistical correlation bovine TB (p=0.006, r=0.148) observed. Slaughterhouses not correlated (p>0.05). origin demonstrated randomness distribution.
