Title: [Isolation of non-type-specific protein antigens of Streptococcus group B].
Abstract: Hydrochloride extracts obtained from group B streptococcal strains of different serotypes have proved to be the source of type-nonspecific protein antigens, precipitated with ethanol and studied by gel chromatography and spectrophotometric scanning in ultraviolet rays. Thus, 2 or 3 antigens, one of them found to be common for streptococci of groups A, B and G, as well as the admixture of group-specific polysaccharide, have been detected. In extracts obtained from group B streptococcal strains of different serotypes a common protein antigen, specific only for group B, has been detected. The suitability of gel chromatography with the use Toyopearl gel HW-55F for the preparative isolation of the specific fraction of protein type-nonspecific antigen with a view to the subsequent study of immune response to group B streptococci has been shown.
