Inhibition growth parameters of M. tuberculosis H37Rv variants exposed to oxidative stress

Strain	Diamide	H2O2	NaClO
		mm
H37Rv	NDa	4.25 ± 0.25	1.35 ± 0.07
Tb461b (Δ-rv2466c)	>8	7.0 ± 0.06b	1.4 ± 0.2
Tb462 (complemented)	ND	4.1 ± 0.1	1.2 ± 0.01
ST49 (Δ-sigH)	>8	>8c	1.25 ± 0.07

^a ND, no inhibition zone was detected.

^b Statistically significant difference compared with values of H37Rv and complemented strain; p < 0.01.

^c Statistically significant difference compared with values of H37Rv and complemented strain; p < 0.005.
