Synergistic Interaction between Boesenbergia rotunda (L.) Mansf. Essential Oil and Cloxacillin on Methicillin-Resistant Staphylococcus aureus (MRSA) Inhibition

Figure 2

Change in quantity of OD₂₆₀-absorbing material of MRSA DMST 20651 after treatment with BREO and CLX, whether taken alone or in combination. CTR = control, CLX = CLX at 256 µg/mL, BREO = BREO at 2 mg/mL, and CLX + BREO = CLX at 16 µg/mL plus BRE at 1 mg/mL. NIS = nisin at 8 µg/mL. The values were represented by the mean and standard error of the mean (SEM) from triplicates. The one-way ANOVA and Tukey’s HSD post hoc tests were compared between results. The different alphabetical symbols indicate a statistically significant difference between groups ().
