- Abstract
- This study investigated biofilm formation, cell surface hydrophobicity, colony spreading, and slime production for 112 Staphylococcus aureus strains isolated from various sources (leaf vegetables, pea leaf, perilla leaf, Kim-bab, person, and animal). When biofilm formation was classified by origin, S. aureus isolated from animal origin showed a significantly higher level of biofilm formation than others (p <= 0.05). When S. aureus groups with different levels of biofilm formation (very strong, strong, moderate, and weak) were evaluated for the correlation with cell surface properties, there was a positive correlation between biofilm formation and hydrophobicity (r=0.926). Biofilm formation and colony spreading on tryptic soy broth (without dextrose) also showed positive correlation (r=0.863). In contrast, biofilm formation and slime production were negatively correlated (r=0.973). Based on these results, the biofilm forming ability of S. aureus differs depending on their origin and might be affected by cell surface properties such as cell surface hydrophobicity.
