Determinación de la prevalencia y factores de riesgo de la brucelosis bovina en la parroquia La Belleza.

Abstract

The objective of this study was to determine the prevalence and risk factors of bovine brucellosis in the parish of La Belleza, province of Orellana. The research was carried out at field and laboratory level, using a proportional stratified sampling based on the total number of cattle in each herd of the members of the "Asociación de Ganaderos 11 de Abril". The research plan included a pre-diagnosis by means of an epidemiological survey, directed to each of the owners of the investigated farms, to determine the main risk factors associated with the presentation of this disease. After this survey, blood samples were collected from 356 animals older than 6 months of age, females and males belonging to the 34 members of the cattle association; blood samples, which consisted of extracting 5 ml of blood from the coccygeal vein of the tail of each animal for the diagnosis of Brucella abortus using the Rose Bengal agglutination test, were transported in refrigerated thermos containers to the veterinary diagnostic and food biosecurity laboratory (LIVEXLAB), certified by the Agency for Regulation and Control of Animal and Plant Health (AGROCALIDAD) in the city of Quito, for analysis and interpretation of the results. Of the total cattle sampled, 100% of the population tested negative for the presence of Brucellosis, presenting a bovine brucellosis prevalence rate of 0% of the population studied. Due to the results of 0% prevalence, it is not possible to determine the possible risk factors associated with the disease; therefore, it is recommended that epidemiological studies be carried out to prevent the presence of bovine brucellosis every year and to maintain the animal health status of the province.
