Physiological parameters of <i>M</i>. <i>tuberculosis</i> during reaeration.

<p>(A) Metabolic activity after extended hypoxia. Reducing activity was determined with XTT. Data are shown in arbitrary units. (B) The ratio of NADH to NAD. (C) Oxygen consumption was measured by methylene blue decolorization. (D) ATP levels in arbitrary units normalized to cell number. Black circles–WT, green squares–RVW7, red triangles–RVW7 pAld-Gen21. Asterisks indicate statistical significance (p<0.05) of the comparison of RVW7 with WT.
