ABSTRACT:
Methods and compositions are provided for the cloning and expression of Streptococcus pyogenes M protein genes, and, in particular, types 5, 6 and 24 genes in single-cell host organisms. The streptococcal M protein produced by the recombinant DNA techniques described herein may be formulated for use as immunogens in vaccines to protect against S. pyogenes infections. The gene for the M protein may further be employed as a molecular probe for the accurate identification of streptococci in infected body tissues and fluids.
