TABLE 2.
Invasion of BAEC by P. gingivalis
| Strain | Bacteria adhering and invading (%)a | Invasion efficiency (%)b |
|---|---|---|
| A7436 | 0.12 ± 0.02 | 0.10 ± 0.03 |
| 381 | 0.11 ± 0.01 | 0.10 ± 0.01 |
| DPG3 | 0.001 ± 0.0003 | 0.001 ± 0.0004 |
a
Defined as the percentage of CFU input that bound to EC; represents both bacteria adhering and invading. Values are the means of triplicate independent determinations from a typical experiment ± standard deviations.
b
Percentage of the inoculum (P. gingivalis) protected from metronidazole killing after the infection period. Values are the means of triplicate independent determinations from a typical experiment ± standard deviations.
