    Estudio retrospectivo de la prevalencia de brucelosis bovina (Brucella abortus) en el Ecuador desde los años 2015 – 2023
    (2024-11) Barragán Taco Edison Macgyver; Núñez Torres Oscar Patricio
    Bovine brucellosis, caused by Brucella abortus, is a zoonotic disease of global importance due to its consequences for both public health and the economy, especially in developing countries in Latin America, Africa, and Asia where control and eradication practices are ineffective. In this study, the prevalence of bovine brucellosis (Brucella abortus) in Ecuador from 2016 to 2023 was analyzed. A total of 1,279 cases of bovine brucellosis reported according to the records of the PhytoZoosanitary Regulation and Control Agency - AGROCALIDAD from 2016 to 2023 were analyzed to evaluate possible differences in the prevalence percentages of brucellosis through the years of study, variations in the months of the year, provinces that make up Ecuador, as well as the regions. Overall, the Sierra and Oriente regions showed the highest prevalence rates, with averages of 15.80 and 15.87%, respectively, while in the Costa Region the average rate reached 10.53%. In the Costa Provinces, prevalence ranged from 6.0% in the province of Santa Elena to 15.2% in Guayas. In the Sierra Region, a wider variation in prevalence levels was observed, ranging from 7.8% in the province of Carchi to 29.6% in the province of Loja, while in the Oriente Region seroprevalence ranged from 6.8% in Morona Santiago to 22.9% in the province of Napo. Finally, bovine brucellosis in Ecuador showed wide variations between the years 2016 to 2023, with values of 14.75% in 2016, which tended to decrease until 2018 with a variation of up to -44% compared to the two previous years, while in 2019 an increase was observed with a variation of 84%, after which it decreased until 2021 and a slight rebound in 2022.
