TABLE 5.
Susceptibility of four S. agalactiae strains against five antimicrobial agents
| Antimicrobial | MIC (μg/ml)a
|
|||
|---|---|---|---|---|
| COH1 (serotype III, cc17) | NEM316 (serotype III, cc23) | 2603V/R (serotype III, cc19) | H36B (serotype Ib, cc1) | |
| Erythromycin | 0.25 | 0.125 | 0.25 | 0.25 |
| Chloramphenicol | 4 | 4 | 4 | 2 |
| Norfloxacin | >8b | >8b | 4 | 4 |
| Acriflavine | 8 | 8 | 8 | 8 |
| Berberine | 32 | 64 | 64 | 32 |
a
MICs were determined from 3 experiments.
b
Value of 8 μg/ml was the higher detection limit for norfloxacin due to acidification and precipitation of media components.
