Biofilm formation in 13  S. aureus (A) and 7  S. epidermidis (B) strains studied. The strains were grown in BHI medium or in BHI supplemented with 1% glucose or 4% NaCl at 37°C for 24 h. Biofilm formation in tissue culture-treated 96-well plates was measured three times, and standard deviations, which were less than 20%, are indicated.
