|---|---|---|---|
| Bacterial strain | Adherent | Internalized | I/Aa |
| C. jejuni wild-type | (7.1 ± 0.6) × 105 | (3.3 ± 0.5) × 104 | 4.6 |
| C. jejuni Cj1242 | (7.6 ± 1.2) × 105 | (6.2 ± 1.9) × 103 | 0.82b |
| C. jejuni ciaB | (7.2 ± 1.2) × 105 | (4.0 ± 0.6) × 103 | 0.56b |
| E. coli XL1-Blue | (1.8 ± 0.4) × 105 | (1.7 ± 1.2) × 102 | 0.09 |
a
Per cent of internalized bacteria relative to adherent bacteria.
b
Internalization of the C. jejuni Cj1242 and C. jejuni ciaB mutants was significantly different from the wild-type strain (P < 0.01) as judged by analysis using unpaired Student's t-tests.
