Fig. 3From: Expression and regulation of phenol-soluble modulins and enterotoxins in foodborne Staphylococcus aureusPSMs expression in sensitive and drug-resistant foodborne S. aureus. The PSMs in single and multiple antibiotic resistant strains were significantly lower than those in sensitive strains, respectively. Results were expressed as the ratio of PSMs levels in tested strains to those in USA300. **p < 0.01Back to article page
