High circulating immunoglobulin A levels in infants are associated with intestinal toxigenic <i>Staphylococcus aureus</i> and a lower frequency of eczema

Early intestinal colonization by toxigenic S. aureus strains seems to promote systemic IgA responses. Furthermore, high levels of APRIL and IgA in the circulation at 4 months of age seem to correlate negatively with allergy development.
