Sensitivities of P. gingivalis strains to hydrogen peroxide. P. gingivalis 33277, the oxyR mutant, and the trx (pgn0373) mutant were grown in standard TSB for 48 h. Hydrogen peroxide (HP, 400 μm) was added to each bacterial culture 8 h after the initial inoculation. Data are the mean optical densities (OD600) of bacterial cultures from four experiments. Error bars represent standard deviations.
