The paper examines antibody responses to S. pyogenes antigens in individuals with and without pharyngitis, finding differences in IgG and IgA levels and correlations with prior immunity.

The paper identifies and refines C4BP-binding patterns in Streptococcus pyogenes M and Enn proteins, showing their conservation and utility for vaccine design.

The paper shows that the M protein of S. pyogenes contributes to resistance against phage A25 infection in human serum by binding IgG and albumin, especially in the absence of fatty acids.
