Resumo: Testing 13 serotypes of Leptospira biflexa as antigens, for the diagnosis of leptospirosis in sheeps and goats by means of the microscopic agglutination test, it was observed that the antigens jequitaia and buenos aires presented the best results. If for sheep sera there was no significant difference between the antigens jequitaia and buenos aires (0,70 < p < 0,50), for goat sera the jequitaia antigen was better than buenos aires (0.01 < p < 0.002). The occurence of some false positive results showed limitations in the specificity of the SAT with Leptospira biflexa strains as antigens.

Para os soros de ovinos não houve diferença entre os antígenos jequitáia e buenos aires (0,70<p<0,50); frente aos soros de caprinos a estirpe jequitáia foi superior à buenos aires (0,01<p<0,002). A ocorrência de resultados falsos positivos (6 a 30%) com estas duas estirpes salienta que uma parcela das reações, pode ser de natureza inespecífica.Universidade de São Paulo.
