Comparison of AAG and hydrophobicity of C. jejuni strain 81-176 and its isogenic mutants
| Strain | Genotype | AAG activitya | Hydrophobicityb |
|---|---|---|---|
| 81-176 | Wild type | 0.031 ± 0.003 | 0.031 |
| 98-248 | flbA | 0.654 ± 0.004c | 4.0c |
| 98-255 | flaA flaB | 0.731 ± 0.008c | 4.0c |
| 98-311 | peb1A | 0.065 ± 0.002 | 0.031 |
a
Bacterial cells were suspended in PBS after extraction twice with DW, and AAG activity was assayed after incubation for 24 h at 25°C. Values are given in AAG optical density units (A600).
b
Minimum concentration (molar) of ammonium sulfate permitting agglutination. Results shown are the mean of three determinations.
c
P < 0.001 compared with wild type.
