TABLE 4.
CadF protein is required for maximal T84 cell association regardless of MOI
| C. jejuni strain | No. of cell-associated bacteria at increasing MOIa:
|
||
|---|---|---|---|
| 3 | 30 | 300 | |
| F38011 | (4.3 ± 0.7) × 104 | (4.3 ± 0.8) × 105 | (2.1 ± 0.2) × 106 |
| cadF mutant | (1.5 ± 0.2) × 104b | (1.3 ± 0.4) × 105b | (1.1 ± 0.2) × 106b |
a
Assays were performed as outlined in Materials and Methods. C. jejuni cell association was measured at 4 h after infection of T84 polarized cells.
b
Value significantly different (P < 0.01) from that obtained with the C. jejuni F38011 wild-type isolate.
