Both senX3 ::Tn and regX3 ::Tn are attenuated, but there appears to be a senX3 -independent contribution of regX3 for long-term Mtb survival in mouse lungs. Separate groups of BalB/c mice (4–5 mice per group) were aerosol-infected with the wild-type CDC1551, senX3::Tn, senX3::Tn Comp, regX3::Tn, and regX3::Tn Comp. *p <0.05; **p <0.01.
