Determinación de la prevalencia de la tuberculosis bovina mediante alergenización en el cantón Morona.

Abstract

The aim of this study was to determine the prevalence of bovine tuberculosis by means of allergenization tests, implemented in the parishes of Macas, Rio Blanco and Proaño, Morona Canton, Province of Morona Santiago. The approach was of documentary and field type, so a strict experimental design that implied the manipulation of the response variable was not used, only the tuberculin testing was applied through intradermal application in the middle third of the right anus - caudal fold of the animal. The first step was to measure the animal's papule and then proceed to the application of 0.1 ml of bovine PPD (purified protein derivative). After 72 hours, the papule of the animal where the applied product was measured again to determine the calculation of averages and frequency. The interpretation of the tuberculin testing measurements are: positive, thickening greater than or equal to 4 mm; inconclusive, thickening greater than 2 mm and less than 4 mm; negative, with thickening less than or equal to 2 mm. As significant findings, 0% prevalence of bovine tuberculosis was found in the parish study areas. It is concluded that based on the sample collection for the 160 tests applied in the parishes of Morona Canton in the province of Morona Santiago, there is a representation of 11.88% of negative prevalence in the diagnosis of bovine tuberculosis in the parish of Macas of Morona Canton, a proportion of 53.13% of negative prevalence in the parish of Proaño and a percentage of negative prevalence in the diagnosis of bovine tuberculosis of 35% in the parish of Rio Blanco. Therefore, strategies are recommended to maintain these findings through the promotion of periodic control campaigns for the eradication of bovine tuberculosis at the national level.
