AirSR regulated exported proteins inhibit complement and antibody mediated opsonophagocytic killing of S. aureus. Sterile TSB and culture supernatants of ATc (250 ng/ml) induced control (Control Cult. Sup) and AirR overproducing S. aureus (WAirR Cult. Sup) were concentrated 50-fold. The serum (A) and complement (B) components of the assay were pre-incubated 30 min with concentrated sterile TSB or individual culture supernatants before addition to the assay. Data represents the mean and standard error of four individual experiments.
