TABLE 3.
Comparison of biofilm formationa on borosilicate glass by V. vulnificus C7184 (wild type), C7184AΩ (pilA mutant), and C7184AΩ (pilA)+
| Strain | A595b |
|---|---|
| C7184 (wild-type) | 4.823 ± 0.10* |
| C7184AΩ (pilA mutant) | 3.571 ± 1.15† |
| C7184AΩ (pilA)+ | 4.730 ± 0.19* |
| Control (no bacteria) | 0.642 ± 0.38‡ |
a
Biofilms were stained with 1% crystal violet, solubilized in 95% ethanol, and the A595 was measured.
b
Values represent the mean ± standard deviation of an average of 24 replicate samples. Values with different symbols significantly differ when compared by one-way ANOVA and Fisher's PLSD at P ≤ 0.001.
