Prevalence of Bovine Tuberculosis (BTB) by post-mortem inspection and bacteriological culture in the municipal slaughterhouse of Mejía canton (Pichincha-Ecuador)
Main Article Content
Abstract
This cross-sectional study was carried out at the Municipal Slaughterhouse of Canton Mejía between May 27 - July 17, 2013 in order to estimate the apparent prevalence of TBB tuberculosis in slaughtered cattle based on macroscopic post-mortem inspection and isolation of M. bovis. In total, 395 heads of cattle were examined during the study period, of which 4 animals were diagnosed with tuberculous lesions compatible with the disease at the lung level, giving an apparent prevalence of 1.01% (IC95%: 0.28% - 2.57 %); while, through bacteriological culture, isolates compatible with M. bovis were identified in 6 animals, giving an apparent prevalence of 1.52% (IC95% = 0.56% – 3.28%). Risk factors such as age, biotype, sex and origin of the animals were not significant in the apparent prevalence of the disease. In conclusion, a significant prevalence of macroscopic lesions and of M. bovis was obtained without obtaining significant association of the factors that predispose to a greater presentation of visible lesions and of the pathogen, therefore, control strategies could not be redirected in the different populations that could be at risk.
