TABLE 3.
CAT and d,d-dipeptidase activities of and chloramphenicol MICs for E. gallinarum BM4174 and derivatives
| Strain | Sp acta (nmol/min/mg of protein) of:
|
Chloramphenicol MIC (μg/ml) | |
|---|---|---|---|
| CAT | d,d-Dipeptidase | ||
| BM4174 | 0 | 92 ± 15.3 (without Van), 73 ± 8.9 (with Van)b | 8 |
| BM4174/pAT78 | 110 ± 41 | 16 | |
| BM4174/pCA11 | 5,889 ± 2,707 | 64 | |
| BM4174/pCA12 | 5,314 ± 128 | 64 | |
a
CAT and d,d-dipeptidase activities were determined in the absence of vancomycin. Values are the means and standard deviations from three independent experiments.
b
Vancomycin (Van) at 4 μg/ml was added to the growth medium to test for the induction of d,d-dipeptidase activity.
