Fig 1. Activity of EB, vancomycin and linezolid against intracellular MRSA USA300 in J774A.1 cells.

MRSA infected J774A.1 cells were treated with EB and control antibiotics (vancomycin and linezolid) for 24 h and the percent bacterial reduction was calculated compared to untreated control groups. The results are given as means ± SD (n = 3). P values of (**, # ≤ 0.05) are considered as significant. EB was compared to controls (**) and to antibiotics (#).
