TABLE 3.
Ratio of HOB to MOB and measured CFU concentration after 4 days of incubation in a microtiter plate. Ratios were inferred from selective plating. Values of ratios are expressed as mean values ± standard deviation (n = 3).
| Combination | Ratio HOB to MOB | Measured CFU concentration (CFU/ml) |
|---|---|---|
| MOB1·HOB7 | 0.60a | 1.6 × 107a |
| MOB4·HOB13 | 1.16 ± 0.01 | 1.19 × 107 ± 0.7 × 106 |
| MOB5·HOB16 | 1.56 ± 0.42 | 1.26 × 107 ± 2.8 × 106 |
| MOB6·HOB15 | 1.30 ± 0.55 | 1.20 × 107 ± 0.3 × 106 |
| MOB6·HOB16 | 0.83 ± 0.12 | 1.13 × 107 ± 3.3 × 106 |
| MOB8·HOB13 | 0.93 ± 0.32 | 1.78 × 107 ± 2.0 × 106 |
| MOB8·HOB15 | 0.89 ± 0.01 | 1.56 × 107 ± 3.4 × 106 |
