Incidencia de Mycobacterium bovis en bovinos faenados en el matadero municipal del cantón Ventanas Provincia de Los Ríos.

Bovine tuberculosis is an infectious disease caused by the GRAN-positive bacterium Mycobacterium bovis, which affects cattle and other domestic and wild animals, being a zoonotic disease that is also present in humans. The present research work, whose main objective was to determine the incidence of Mycobacterium bovis in cattle slaughtered in the municipal slaughterhouse of Cantón Ventanas province of Los Ríos, evaluated bovine tuberculosis and its incidence through the correlation of variables; according to age, sex, racial group and origin; in addition, a macroscopic post mortem analysis of organs, lymph nodes and viscera was carried out. This research work used a descriptive method of macroscopic experimental observation. This method was based on the percentage method to determine the percentage of incidence of Mycobacteriun bovis, taking the following parameters, 95% confidence and 5% error, and by calculating the sample size, a total of 200 animals to be analyzed in the post mortem inspection was estimated, The same was obtained from a population of 420 cattle that are slaughtered on average in the municipal slaughterhouse of the canton of Ventanas that exist between two months that the study lasted, on the other hand it was obtained as a result that of the 200 cattle inspected for Mycobacteriun bovis, through the post mortem analysis of organs, viscera and lymph nodes, 0 cases of antaomopathological alterations compatible with bovine tuberculosis were reflected, reporting 0% in positive cases and 100% in negative cases. In conclusion, during the study carried out on Mycobacterium bovis in slaughterhouses, there were no positive cases compatibles with the disease.

La tuberculosis bovina es una enfermedad infecciosa ocasionada por la bacteria GRAN- positiva Mycobacterium bovis, el cual afecta al ganado bovino y a otros animales domésticos y salvajes, siendo una enfermedad zoonotica que también está presente en humanos. el presente trabajo de investigación, que tuvo como objetivo principal determinar la incidencia de Mycobacterium bovis en bovinos faenados en el matadero municipal del Cantón Ventanas provincia de Los Ríos, se evaluó la tuberculosis bovina y su incidencia mediante la correlación de las variables; según edad, sexo, grupo racial y su procedencia; además se realizó un análisis macroscópico post morten de los órganos, ganglios y viseras. Este trabajo de investigación utilizó un método descriptivo de observación experimental macroscópica. el mismo que se basó en el método porcentual para determinar el porcentaje de incidencia a Mycobacteriun bovis, tomando los siguientes parámetros, de confianza del 95% y de error del 5% y mediante un cálculo del tamaño de la muestra, se estimó un total de (Nº 200) animales a ser analizados en la inspección post morten, el mismo que se obtuvo de una población de 420 bovinos que se faenan en promedio en el matadero municipal del cantón Ventanas que son existente entre dos meses que duro el estudio, por otro lado se obtuvo como resultado que de los 200 bovinos inspeccionados para Mycobacteriun bovis , mediante el análisis post morten de los órganos, viseras y ganglios , se reflejó 0 casos de alteraciones anatomopatológicas compatibles a tuberculosis bovina reportando el 0% en casos positivos y un 100% en casos negativos. En conclusión, durante el estudio realizado sobre Mycobacteriun bovis en mataderos no existieron casos positivos compatible a la enfermedad.
