| Method of cell growth | Treatmenta | Total viable count | Pb |
|---|---|---|---|
| Planktonic | PBS | (1.04 ± 0.08) × 107 | |
| WLBU2 | (0.00 ± 0.00) × 107 | <0.0001 | |
| Amoxicillin | (1.00 ± 0.15) × 107 | NS | |
| Metronidazole | (1.02 ± 0.07) × 107 | NS | |
| Biofilm | PBS | (1.75 ± 0.13) × 104 | |
| WLBU2 | (0.20 ± 0.27) × 104 | NS | |
| Amoxicillin | (2.75 ± 0.07) × 104 | NS | |
| Metronidazole | (2.86 ± 0.57) × 104 | NS |
a
All antimicrobials were used at a concentration of 2 μM.
b
NS, not significant; P > 0.05 by a t test that was adjusted when necessary for unequal variance.
