title: Immunoprecipitation and opsonic cross-reaction between type-14 pneumococcus and group-B streptococcus type III.
abstract: Antisera directed against type-14 pneumococcus was opsonic for several strains of type-III group-B streptococcus. Furthermore, the polysaccharide antigen in the polyvalent pneumococcal vaccine reacted to form precipitation lines with antisera directed against type-14 pneumococcus and group-B streptococcus type III Immunisation with currently available pneumococcal vaccine may provide opsonic antibody against group-B streptococci and provide a method of preventing neonatal group-B streptococcal infections.
