Synergistic Effect between Cryptotanshinone and Antibiotics against Clinic Methicillin and Vancomycin-Resistant Staphylococcus aureus

Figure 5

Time-kill curves of MIC or 1/2 MIC of cryptotanshinone (CT), ampicillin (AMP), oxacillin (OXA), and vancomycin (VAN) alone and its combination with 1/2 MIC of AMP or OXA, and VAN against MRSA 7, 8, and 9 isolates. Bacteria were incubated with MIC of CT (●), AMP (○), OXA (), and VAN (), and 1/2 MIC of CT + 1/2 MIC of AMP (●), 1/2 MIC of CT + 1/2 MIC of OXA (○), and 1/2 MIC of CT + 1/2 MIC of VAN () over time. CFU: colony-forming units.
