Seroprevalencia y factores de riesgo asociados a Brucella spp. en ovinos en Ecuador

Abstract

Abstract: This study analyzes the seroprevalence and risk factors associated with Brucella spp. in sheep in Ecuador, a zoonotic disease that affects both animals and humans, representing a challenge for public and veterinary health. Its economic impact is significant, as it reduces livestock productivity, and the lack of accurate epidemiological data makes it difficult to design effective control strategies. The study was conducted on 970 sheep sera obtained in 11 provinces of Ecuador, using Rose Bengal screening, complemented by indirect ELISA verification. Associated risk factors were determined using a Logistic Regression model. This study highlights the need to implement measures such as strengthening biosecurity, vaccination programs, ongoing monitoring, and training for livestock farmers, emphasizing the importance of proper sanitary management. These actions will not only reduce the incidence of the disease, but also protect human health and ensure the sustainability of the livestock sector in Ecuador.
