Delivery and expression of a heterologous antigen on the surface of streptococci

Abstract excerpt

We have developed a system in which a foreign antigen replaces nearly all of the surface-exposed region of the fibrillar M protein from Streptococcus pyogenes and is fused to the C-terminal attachment motif of the M molecule. The fusion protein is thus expressed on the surface of Streptococcus gordonii, a commensal organism of the oral cavity. The antigen chosen to be expressed within the context of the M6...
