TABLE 3.
Susceptibility of S. aureus to tunicamycin
| S. aureusa | MIC (μg/ml)b
|
|
|---|---|---|
| TUN | TUN + RES | |
| RN6390 | 8 | 4 |
| QT7c | 4 | 4 |
| RN6390(pLI50) | 8 | 4 |
| RN6390(pLI50-tet38) | 64 | 16 |
| QT7(pLI50) | 4 | 4 |
| QT7(pLI50-tet38) | 16 | 4 |
All strains harboring plasmid pLI50 were grown in the presence of chloramphenicol (20 μg/ml) and at 37°C.
TUN, tunicamycin; RES, reserpine at 20 μg/ml.
QT7 is a tet38 mutant.
