Minimal Inhibitory Concentration (MIC) of penicillin, vancomycin and daptomycin for growth of wild-type and srtA mutant bacteria

Actinomyces oris strain		MIC (μg ml−1)a
		Vancomycin	Daptomycin	Penicillin
MG-1		2.03 ± 0.45b	4.00 ± 1.73b	<0.016
ΔsrtA/ pTetR-Ω-SrtA	0 ng/ml AHT	1.08 ± 0.29b	1.67 ± 0.29b	<0.016
	10 ng/ml AHT	1.37 ± 0.13	3.17 ± 0.29	<0.016
	100 ng/ml AHT	2.45 ± 0.58	3.33 ± 0.58	<0.016

^aThe MICs were determined with Etest stripes as described in the Experimental Procedures. Mean values and standard deviations were calculated from three independent experiments.
