Characteristics in adherence of streptococci and Staphylococcus aureus isolated from various infective skin lesions: serum IgA decreases adherence of Streptococcus pyogenes but not Staphylococcus aureus.
We characterized adherence of streptococci and Staphylococcus aureus strains isolated from various infective skin lesions in terms of hydrophobicity, negative charge, tube adherence, slime production, and influence on adherence to coverslips by plasma and serum immunoglobulins. High hydrophobicity was more frequently observed in Streptococcus pyogenes strains than in Streptococcus agalactiae strains (P < 0.01) and S. aureus strains (P < 0.001) and slime production was more frequently observed in S. agalactiae strains than in S. pyogenes strains (P < 0.05). Serum IgA decreased adherence to coverslips of S. pyogenes strains but not that of S. aureus strains.
