Brucellosis in sheep has received a major focus, since it is a disease that affects the reproductive systemof animals, causing serious impairment in the productive sector. Thus, three methods for the diagnosis of ovinebrucellosis were evaluated as goal, the indirect ELISA test, the AGID technique and the PCR. Therefore, weused 211 sheep blood samples arising from properties of nine municipalities of the homogeneous micro-regionof Teresina, Piaui. The 211 blood samples were subjected to the serologic testing and PCR to detect anti-B. ovisantibodies, and Brucella ovis DNA, respectively. Positive results in serological tests were obtained, 36 (17.06%)positive in the AGID test and seven (3.31%) positive to the ELISA test, however, there were no positive results inthe PCR technique. The use of the techniques for the diagnosis of B. ovis infection is satisfactory, but the choiceof blood as the biological sample for performing the direct diagnosis of ovine brucellosis is not recommended.(AU)
