All the chemicals tested for synergy with penicillin G (Table ) were purchased from ChemBridge. Purity was standard, at 85-100% based on HPLC profiles. All standard chemicals and reagents were purchased from Sigma Aldrich and/or Fisher Scientific. All bacterial strains used in this study are reported in Table . MRSA growing without antibiotic served as the positive control for growth, while uninoculated CA-MHB served as negative control. We ensured MRSA status by testing the MIC of vancomycin was ≤2 μg/mL and MIC of oxacillin was >2 μg/mL. In comparison, Escherichia coli strains ATCC 35218 and ATCC 25922, and were unaffected by vancomycin.
