Abstract

Objective. Describe the situation of the bovine brucellosis in the Atlantic Coast and Antioquia (CAA) by analysis of epidemiological indicators during 2005-2013. Materials and methods. The data was obtained from epidemiological reports of the Colombian Agricultural Institute and the National Agricultural Census 2014. The annual departmental average of the variables studied was compared and it was performed a temporal analysis through graphical representation. Results. 44% of the positive farms were focused on the CAA; the positivity rate of farms in the CAA (27.9%) was higher and statistically significant when related to the average rate in the country (24.8%) being promoted by the least producing departments. Regarding to the cattle population, the CAA concentrated 47.0% of positive cattle in the country; however, the bovine positivity rate (5.8%) was statistically equal to the national average (5.3%); yet, the departments with lower cattle population had the highest rates. The best surveillance for bovine brucellosis was observed between 2005 and 2009, in contrast, during 2010, 2011 and 2013 there was a considerable reduction in the number of diagnoses, in both farms and cattle. In the least producing departments the temporary distribution of epidemiological indicators favored more the presence of the disease. Conclusions. The National Prevention Control and Eradication Program of Bovine Brucellosis in the CAA presented promising results, however, the lack of continuity in the diagnostic surveillance during some years and mainly in the least producing departments affected negatively their development.
