Geometric mean minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) in broth and porcine serum and MBC/MIC and Mueller-Hinton broth (MHB)/serum ratios for gamithromycin against selected Streptococcus suis isolates (n = 47).
| Test matrix | MIC (mg/L) | MBC (mg/L) | MBC/MIC ratio |
|---|---|---|---|
| MHB | 0.443 | 1.534 | 3.45 |
| Serum | 0.015 | 0.137 | 8.87 |
| MHB/serum ratioa | 28.86 | 11.23 | NA |
P <0.005 for MIC or MBC differences between MHB and serum (paired Student's t-test); NA, not applicable.
