Prevalencia de brucelosis bovinas mediante el método de rosa de bengala en fincas ganaderas del Cantón Santa Rosa.

Abstract

The research work was carried out in the province of El Oro, in the parishes of the Santa Rosa canton, we worked with 376 bovines, taking into account the study variables, the blood sample was taken from the coccygeal vein, the same that were transported to the Technical University of Machala, to the LABORATORY OF THE FACULTY OF AGRICULTURAL SCIENCES in a refrigeration cooler to later perform centrifugation and extract the blood serum to which the Rose Bengal reagent was added to determine by observation the agglutination if it is a positive reactor to brucella abortus. For the statistical analysis, 7 parishes of the Santa Rosa canton were selected where, based on the Agrocalidad list, livestock farms with more than 50 animals were chosen, taking into account the 4 variables under study: origin, race, age, sex and type of exploitation. At the end of the investigation, we had 12 positive cases out of the total of 376 samples, thus considering that the prevalence of bovine brucellosis in the Santa Rosa Canton is 3.19%. The positive cases occurred in female bovines with provenances from Bellavista, Bellamaria and La Avanzada, 11 in the Brahmin breed and 1 in the Gyr breed, with a greater predominance of the type of meat exploitation.
