S. aureus with D-alanine-deficient LTA and WTA is susceptible to the growth inhibition by NaP. (A) WT, (B) ΔltaS, (C) ΔtagO, (D) Δlgt, (E) ΔdltA, (F) ΔltaS/pM101-ltaS, (G) ΔtagO/pStagO, (H) Δlgt/pSlgt or (I) ΔdltA/p0793 was inoculated and cultured in the presence or absence of 12.5 mM of NaA, NaP, or NaB. The optical density at 600 nm was measured hourly. (J–L) The MIC/MBC test for NaP was conducted using the microdilution method with (J) WT, (K) ΔdltA, or (L) ΔdltA/p0793. The MIC, the concentration of NaP which completely inhibited growth, is indicated with an arrow. Data shown are the mean values ± SD of triplicate samples and are representative of at least three similar independent experiments.
