TABLE 3.
Enhanced expression of type 1 pili in E. coli LF82-ΔyfgL isogenic mutant does not modify invasion level
| Strain | Yeast aggregation (titer)a | Invasion level (%)b |
|---|---|---|
| LF82 | 1/8 | 100.00 ± 0.00 |
| LF82-ΔyfgL | 1/2 | 8.31 ± 0.69 |
| LF82-ΔyfgL/pPBI01 | 1/8 | 9.64 ± 0.44 |
a
Yeast cell aggregation was monitored visually, and the titer was recorded as the last dilution giving a positive aggregation reaction.
b
Percentage of intracellular bacteria relative to that obtained for AIEC strain LF82, which was set at 100%. Each value is the mean ± standard error of the mean of at least four separate experiments.
