| Strain | Hydrophobicity (%)a |
|---|---|
| Xc | 53.2 ± 2.2 |
| Xc11 | 32.6 ± 2.3b |
| Xc16 | 51.5 ± 3.5 |
| Xc24R | 99.3 ± 0.8b |
| LM7 | 44.2 ± 3.5 |
| LM7DR | 78.6 ± 2.8b |

| KT6219DR | 82.7 ± 1.0b |
a
The bacterial cell suspension (3 ml, OD550 = 0.6) was mixed with 0.3 ml of hexadecane. The cell surface hydrophobicity was calculated as the percentage loss of OD of the aqueous phase relative to the initial bacterial cell suspension. Each value represents the mean ± standard deviation for assays performed five times.
b
P < 0.01 compared with the value of the wild-type strain of each serotype.
