Biofilm formation. Upper panel showed representative photographs of biofilms formed by wild type V. cholerae (A) and toxR mutant strain (B). Lower panel showed representative measurement of the absorbance, which is directly proportional to the concentration of biofilm-associated crystal violet formed by wild type V. cholerae (A) and toxR mutant (B) strains. Data indicates mean ± SD of three independent experiments.
