Résumé

Staphylococcus aureus persistently colonizes the nasopharynx of about one-third of the human population, a key risk factor for community- and hospital-acquired invasive infections. Current strategies for S. aureus decolonization include topical and systemic administration of antibiotics, which is associated with selection for antibiotic resistance and posttreatment recolonization. Using a mouse model for S. aureus colonization, we show here that systemic administration of a recombinant monoclonal antibody neutralizing staphylococcal protein A (SpA) can stimulate antibacterial immunoglobulin G and immunoglobulin A responses and promote S. aureus decolonization. These results suggest that antibody neutralizing SpA, a B-cell superantigen, may also be useful for S. aureus decolonization in humans.
