El presente trabajo se desarrolló con el objetivo de evaluar y comparar dos de los esquemas de inmunización reportados para la obtención de sueros hiperinmunes específicos a Leptospira en conejos. Los esquemas recomendados fueron comparados por el Subcomité Taxonómico Internacional de Leptospira (TSCL) y por el Ministerio de la Agricultura de Cuba (MINAGRI), empleando como antígenos cepas de referencia correspondientes a los serogrupos Australis y Tarassovi. Se evaluaron las dinámicas de aglutininas desarrolladas frente a cada antígeno mediante cada esquema utilizando la técnica de aglutinación microscópica. Se evaluó asimismo la especificidad de los antisueros obtenidos frente a 11 serogrupos de Leptospira interrogans. Los títulos de aglutininas obtenidos mediante el esquema recomendado por el TSCL fueron superiores a los obtenidos mediante el esquema recomendado por el MINAGRI. Los antisueros producidos mediante ambos esquemas de inmunización fueron altamente específicos para sus respectivos serogrupos homólogos con ausencia de reactividad cruzada detectable por microaglutinación frente a todos los serogrupos heterólogos evaluados.]]></p></abstract>

The purpose of this study was to evaluate and compare two immunization schedules reported for obtaining Leptospira specific hyperimmune sera in rabbits. The schedules recommended by the International Taxonomic Subcommittee on Leptospira (TSCL) and the Cuban Ministry of Agriculture (MINAGRI) were compared using reference strains of the serogroups Australis and Tarassovi as antigens. Agglutinin dynamics were evaluated by the microscopic agglutination test and crossreactivity of antisera was determined using 11 different serogroups. Agglutinin titers obtained with the schedule recommended by TSCL were higher than those obtained with the schedule recommended by MINAGRI. Antisera produced by both schedules were highly specific and no cross-reactivity was detected.]]></p></abstract>
