Relative expression levels of cydA and cydB in M. tuberculosis clinical isolates.
| Clinical isolates # | Fold change in expression relative to H37Rv | |
|---|---|---|
| cydA | cydB | |
| N0153 | 0.64 ± 0.02 | 0.63 ± 0.02 |
| N0157 | 0.59 ± 0.05 | 0.58 ± 0.04 |
| N0052 | 0.35 ± 0.08 | 0.41 ± 0.1 |
| N0155 | 0.31 ± 0.02 | 0.32 ± 0.02 |
| N0145 | 0.15 ± 0.01 | 0.16 ± 0.02 |
RNA was extracted from early log-phase standing cultures growing in 7h9 liquid broth medium. Gene expression was normalized relative to H37Rv, sigA gene was used as an endogenous control.
