In Vitro Antibacterial Experiments of Qixingjian Decoction and Its Synergistic Interaction with Oxacillin against Clinical Isolates of Methicillin-Resistant Staphylococcus aureus

Figure 7

Different concentrations of QXJT, OX, and QXJT + OX were added to the final concentration of 5 × 105 CFU/mL and incubated at 37°C for 24 h. The expression levels of sea, seb, and tst were compared. vs. control group; vs. 1/2OX or OX group. (a) Relative gene expression of MRSA2007118 strain sea under different concentrations of drug treatment. (b) Relative gene expression of MRSA2008043 strain sea under different concentrations of drug treatment. (c) Relative gene expression of MRSA2007118 strain seb under different concentrations of drug treatment. (d) Relative gene expression of MRSA2008043 strain seb relative gene expression. (e) MRSA2002118 strain tst relative gene expression under different concentrations of drug treatment. (f) MRSA2008043 strain tst relative gene expression under different concentrations of drug treatment. (g) Relative gene expression of mecA in strain MRSA2007118 under different concentrations of drug treatment. (h) Relative gene expression of mecA in strain MRSA2008043 under different concentrations of drug treatment.
