S. aureus binds sIgA epitope-independently via SpA. sIgA deposition of nasal sIgA of individual study participants (n = 46) on S. aureus USA300 JE2 wildtype (WT) and the SpA-AA mutant deficient for binding of antibody Fab regions. Statistical differences were tested by paired t test. A single sample (#) did not follow the trend of lower sIgA deposition on the SpA-AA mutant
