Abstract
Leptospirosis vaccines that elicit broad protection against a range of pathogenic Leptospira spp. would overcome a major drawback of currently licensed bacterin vaccines. Live attenuated vaccine produced from a lipopolysaccharide (LPS) mutant strain of L. interrogans serovar Manilae M1352 (Live M1352) stimulated better protective efficacy than heat killed M1352 (HK M1352) against a heterologous challenge with L. interrogans serovar Pomona. To identify antigens of Live M1352 potentially responsible for cross protection, in vivo-induced antigen technology (IVIAT), a powerful tool to identify in vivo-induced (ivi) genes expressed during infection, was employed in this study. Pooled sera from ha..
