Prevention of Bacteriophage Adsorption to Staphylococcus aureus by Immunoglobulin G

AUTOR(ES)
RESUMO

Normal human and rabbit sera when incubated with Staphylococcus aureus inhibit the adsorption of bacteriophages. The bacteriophage adsorption was also inhibited by separated normal immunoglobulin M (IgM), F(ab′)2, and Fab-fragments of IgG. No inhibition was obtained with myeloma IgG or Fc-fragments of normal human and rabbit IgG. The results indicate that the serum inhibition of bacteriophage adsorption to S. aureus is not due to a binding of IgG to protein A on the surface of S. aureus.
