Capsular polysaccharides (CPSs) are known to induce protective antibodies; however, it is not feasible to develop CPS-based vaccines that cover all of the 90 disease-causing serotypes. We applied a genomic approach and described the antibody repertoire for pneumococcal proteins using display libraries expressing 15\u2013150 amino acid fragments of the pathogen's proteome. Serum antibodies of exposed, but not infected, individuals and convalescing patients identified the ANTIGENome of pneumococcus consisting of \u223c140 antigens, many of them surface exposed. Based on several in vitro assays, 18 novel candidates were preselected for animal studies, and 4 of them showed significant protection against lethal sepsis. Two lead vaccine candidates, protein required for cell wall separation of group B streptococcus (PcsB) and serine\/threonine protein kinase (StkP), were found to be exceptionally conserved among clinical isolates (&amp;gt;99.5% identity) and cross-protective against four different serotypes in lethal sepsis and pneumonia models, and have important nonredundant functions in bacterial multiplication based on gene deletion studies. We describe for the first time opsonophagocytic killing activity for pneumococcal protein antigens. A vaccine containing PcsB and StkP is intended for the prevention of infections caused by all serotypes of pneumococcus in the elderly and in children.<\/jats:p>","DOI":"10.1084\/jem.20071168","type":"journal-article","created":{"date-parts":[[2007,12,31]],"date-time":"2007-12-31T20:13:27Z","timestamp":1199132007000},"page":"117-131","update-policy":"https:\/\/doi.org\/10.1084\/jem.crossmarkpolicy","source":"Crossref","is-referenced-by-count":243,"title":["Discovery of a novel class of highly conserved vaccine antigens using genomic scale antigenic fingerprinting of pneumococcus with human antibodies"],"prefix":"10.1084","volume":"205","author":[{"given":"Carmen","family":"Giefing","sequence":"first","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas L.","family":"Meinke","sequence":"additional","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Hanner","sequence":"additional","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tama\u0301s","family":"Henics","sequence":"additional","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duc Bui","family":"Minh","sequence":"additional","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dieter","family":"Gelbmann","sequence":"additional","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Urban","family":"Lundberg","sequence":"additional","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beatrice M.","family":"Senn","sequence":"additional","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Schunn","sequence":"additional","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andre","family":"Habel","sequence":"additional","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Birgitta","family":"Henriques-Normark","sequence":"additional","affiliation":[{"name":"2Department of Bacteriology, Swedish Institute for Infectious Disease Control, 171 82 Solna, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A\u030ake","family":"O\u0308rtqvist","sequence":"additional","affiliation":[{"name":"3Department of Infectious Diseases, Karolinska University Hospital, 171 76 Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mats","family":"Kalin","sequence":"additional","affiliation":[{"name":"3Department of Infectious Diseases, Karolinska University Hospital, 171 76 Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"von Gabain","sequence":"additional","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eszter","family":"Nagy","sequence":"additional","affiliation":[{"name":"1Intercell AG, 1030 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"291","published-online":{"date-parts":[[2007,12,31]]},"reference":[{"key":"2023072915435452300_BIB1","year":"2007"},{"key":"2023072915435452300_BIB2","doi-asserted-by":"crossref","first-page":"1139","DOI":"10.1016\/S0140-6736(05)71876-6","volume":"365","year":"2005","journal-title":"Lancet."},{"key":"2023072915435452300_BIB3","doi-asserted-by":"crossref","first-page":"71","DOI":"10.1016\/S1473-3099(03)00514-0","volume":"3","year":"2003","journal-title":"Lancet Infect.
