Frequência de carcaças condenadas com lesões sugestivas de tuberculose bovina em abatedouro frigorífico em Santo Antônio de Jesus - BA

Abstract

Bovine Tuberculosis (TB) is an infectious disease caused by Mycobacterium bovis, and is usually characterized by the formation of nodular granulomas known as tubers. Although defined as a debilitating chronic disease, Bovine Tuberculosis (TB) may occasionally present an acute, rapid and progressive course. It is a zoonosis that has as its main reservoir cattle, but infects a wide variety of animal species among them being human. The objective of this study was to verify the frequency of condemned carcasses with lesions suggestive of Bovine Tuberculosis in a slaughterhouse in the municipality of Santo Antônio de Jesus-Ba from January 2007 to December 2016 and to verify the statistical correlation between Human Tuberculosis TH) and Bovine Tuberculosis (TB) with the municipalities of origin and the reported cases of HT of these municipalities. 857,776 cattle and 178 carcasses were slaughtered in this period with lesions suggestive of Bovine Tuberculosis (TB), with a frequency of 0.020%. These frequencies varied with higher percentages in 2008 and 2009 and lower percentages in 2011 and 2014. In the mentioned period, a total of 64,114 cases of HT were reported in the municipalities from which the animals that originated the condemned carcasses originated and 178 condemned carcasses with suggestive lesions of TB. A positive correlation was not observed between the variables TB and TH, which was very low and directly proportional (ρ = 0.133), that is, there was no significant correlation between the variables.
