Iron Deprivation Affects Drug Susceptibilities of Mycobacteria Targeting Membrane Integrity

Figure 6

Passive diffusion in response to iron deprivation. (a) Passive diffusion displayed by extracellular concentrations of EtBr for M. smegmatis cells grown in the absence (control) and the presence of 2,2, BP (35 μg/mL) as described in Section 2. Means of O.D₂₈₅ ± SD of three independent sets of experiments are depicted on -axis with respect to time (minutes) on -axis ( depicts significant difference with ). (b) Passive diffusion displayed by extracellular concentrations of EtBr for M. smegmatis cells grown in RIF alone (control) and in the presence of 2,2, BP (35 μg/mL) as described in Section 2. Means of O.D₂₈₅ ± SD of three independent sets of experiments are depicted on -axis with respect to time (minutes) on -axis ( depicts significant difference with ).
