Etest assessment of WT, Δlaz, and Δlaz/Plac::laz MIC values.
| FA1090 (WT)a | Δlaza | Δlaz/Plac::laza | |
|---|---|---|---|
| Polymyxin B | 64 | 64 | 64 |
| Azithromycin | 0.064 | 0.064 | 0.5b |
| Cefotaxime | 0.004 | 0.004 | 0.004 |
| Ampicillin | 0.125 | 0.064 | 0.125 |
| Tetracycline | 0.125 | 0.125 | 0.125 |
| Benzylpenicillin | 0.064 | 0.064 | 0.064 |
| Vancomycin | 8 | 8 | 8 |
| Gentamicin | 4 | 4 | 4 |
| Tobramycin | 8 | 8 | 8 |
| Ceftazidime | 0.032 | 0.032 | 0.032 |
aMIC values are presented in μg/mL. bConstruct used for complementation encodes erythromycin resistance, which also confers resistance to azithromycin.
