Abstract
La presente investigación tuvo como fin determinar la prevalencia de brucelosis y los factores de riesgo ligados a la presencia de la enfermedad en las ganaderías de Imbabura que proveen leche a la empresa Floralp S.A. Para establecer la prevalencia se recurrió a la Prueba de Fluorescencia Polarizada (FPA) en leche de tanque, por su alta sensibilidad y especificidad, como prueba de tamizaje y que diagnosticó dos Unidades de Producción Animal (UPAs) positivas a la presencia de anticuerpos de la enfermedad, lo que representó una prevalencia de 4,44%. En las UPAs código 109 y 173 que resultaron positivas, se tomaron muestras serológicas a todos los animales en producción y se aplicó el test de Rosa de Bengala (RB), posteriormente a las muestras positivas se les realizó la prueba de ELISA competitivo como prueba confirmatoria. La prevalencia en cada UPA fue de 10% y 15,79%, respectivamente. Los principales factores de riesgo asociados a la presencia de Brucelosis fueron: desinfección de las parideras, existencia de terneros débiles, procedimientos de cuarentena, realización de pruebas diagnósticas, presencia de metritis e introducción de animales de reemplazo a las UPAs.
The purpose of this research was to determine the prevalence of brucellosis and risk factors linked to the presence of the disease in the Imbabura cattle farms that provide milk to the company Floralp S.A. To establish the prevalence, the Polarized Fluorescence Test (FPA) in tank milk was used, due to its high sensitivity and specificity, also as a screening test and which diagnosed two positive APUs to the presence of disease antibodies, which represented a prevalence of 4.44% (2/45). In the positive APUs code 109 and 173, serological samples were taken from all the animals in production and the Rose Bengal (RB) test was performed, then the competitive ELISA test was applied to the positive samples as a confirmatory test. The prevalence in each APU was 10% and 15.79%, respectively. The main risk factors associated with the presence of Brucellosis were: disinfection of the calves, existence of weak calves, quarantine procedures, performing diagnostic tests, presence of metritis and introduction of replacement animals to the UPAs.
