Thus far, attempts to develop effective leptospirosis vaccines, both for humans and animals, have failed to induce immune responses capable of conferring protection and simultaneously preventing renal colonization. In this study, we evaluated the protective immunity induced by subunit vaccines containing seven different recombinant\n            <jats:named-content content-type=\"genus-species\">Leptospira interrogans<\/jats:named-content>\n            outer membrane proteins, including the carboxy-terminal portion of the immunoglobulinlike protein A (LigA\n            <jats:sub>C<\/jats:sub>\n            ) and six novel antigens, combined with aluminum hydroxide (alum) or\n            <jats:named-content content-type=\"genus-species\">Salmonella<\/jats:named-content>\n            flagellin (FliC) as adjuvants.

Immunization with LigA\n            <jats:sub>C<\/jats:sub>\n            , either with alum or flagellin, conferred protective immunity but did not prevent renal colonization. Similarly, animals immunized with LigA\n            <jats:sub>C<\/jats:sub>\n            or LigA\n            <jats:sub>C<\/jats:sub>\n            coadministered with six leptospiral proteins with alum adjuvant conferred protection but did not reduce renal colonization. In contrast, immunizing animals with the pool of seven antigens in combination with flagellin conferred protection and significantly reduced renal colonization by the pathogen. The present study emphasizes the relevance of antigen composition and added adjuvant in the efficacy of antileptospirosis subunit vaccines and shows the complex relationship between immune responses and renal colonization by the pathogen.\n          <\/jats:p>","DOI":"10.1128\/cvi.00285-15","type":"journal-article","created":{"date-parts":[[2015,6,25]],"date-time":"2015-06-25T01:55:52Z","timestamp":1435197352000},"page":"965-973","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":37,"title":["Protective Immunity and Reduced Renal Colonization Induced by Vaccines Containing Recombinant Leptospira interrogans Outer Membrane Proteins and Flagellin Adjuvant"],"prefix":"10.1128","volume":"22","author":[{"given":"D.","family":"Monaris","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Bacteriologia, Instituto Butantan, S\u00e3o Paulo, SP, Brazil"},{"name":"Faculdade de Medicina Veterin\u00e1ria e Zootecnia, Universidade de S\u00e3o Paulo, S\u00e3o Paulo, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
