摘要
Cold spot genes of S. pneumoniae are disclosed that encode surface proteins that are universally conserved among known strains and have exceptionally low incidence of allelic variation. Cold spot polypeptides encoded by the genes that are antigenic on the S. pneumoniae cells on which they are expressed are candidates for immunogenic compositions capable of eliciting antibodies able to react with all or nearly all strains of S. pneumoniae, thus providing an improvement over currently available S. pneumoniae vaccines that protect inoculated individuals against a maximum of about 23 of the 94 or so known serotypes of S. pneumonia. 展开▼
