Brucellosis, caused by Brucella abortus is a major disease of cattle and zoonosis. In order to estimate the bovine brucellosis prevalence in Costa Rica (CR), total 765 herds (13078 bovines) from six regions CR were randomly sampled during 2012–2013. A non-random sample 7907 (532199 regions, arriving for diagnoses 2014–2016 Rican Animal Health Service was also studied. The estimated Rose Bengal test (RBT) ranged 10.5%-11.4%; alternatively, testing RBT positives iELISA, 4.1%-6.0%, respectively. However, are not vaccinated with B. S19 but RB51 (vaccination coverage close 11%), under these conditions displays 99% specificity sensitivity. Therefore, herd depicted random analysis stands as feasible assessment then, recommended value case planning an eradication program CR. Studies three decades reveled that has increased identified biochemical molecular studies etiological agent brucellosis. Multiple locus variable-number tandem repeat analysis-16 revealed four clusters. Cluster one intertwined isolates other countries, while clusters two have only representatives widely distributed all country may be primary source. seem restricted specific areas implications our findings, relation control CR, critically discussed.
