Post-antibacterial effects of artonin E and streptomycin in Staphylococcus aureus ATCC 25923 and MRSA BAA-1720.

Bacterial growth inhibition was expressed in mm and measured using the disc diffusion assay. Test was performed in triplets. The mean and standard deviations are provided indicating the inhibition diameter. The MIC/MBCs of artonin E were similar for both S. aureus strains, and comparable MIC and MBCs were obtained using streptomycin. Minimum inhibitory concentration indicates that S. aureus ATCC 25923 was not grown after exposure to 3.9 μg/mL MIC of artonin E or 1.95 μg/mL of streptomycin, respectively 3.9 μg/mL MIC after the exposure of MRSA BAA-1720 to artonin E or less than 1.0 μg/mL MIC to Streptomycin.Post-antibacterial effects of artonin E and streptomycin in Staphylococcus aureus ATCC 25923 and MRSA BAA-1720.
