title: [The enhancement of the immunogenicity of streptococcal group-A M protein by conjugation with a synthetic polyelectrolyte].
abstract: Immunization with the polypeptide fragment of group A streptococcal protein M conjugated with the copolymer of acrylic acid and N-vinylpyrrolidone in complete Freund's adjuvant has been found to lead to a sharp increase in the level of antibodies to the type-specific determinants of protein M, detected in the enzyme immunoassay (EIA). The possibility of the application of such sera to preliminary typing of streptococci in EIA with the use of whole microbial cells as antigens has been shown. The data on high activity of the sera thus obtained in the bactericidal test with streptococci of the homologous type are presented. Recommendations on the use of sera obtained by the above method for highly precise typing of the virulent cultures of group A streptococci in the bactericidal test are given.
