Assessment of the immunogenicity of the leptospiral LipL32, LigAni, and LigBrep recombinant proteins in the sheep model

Veterinary leptospirosis vaccines are composed of bacterins and present limitations, for example, the need for bacteriological culture and serovar-dependent immunity. Recombinant antigens represent a promising alternative. LigAni, LigBrep, and LipL32 proteins have been shown to promote a protective immune response against the homologous challenge in hamsters. Therefore, the next step is to evaluate the immunological properties of these...
