Bile salts reduce biofilm formation through vtrA. Levels of biofilm growth from strains grown statically in (a) non-inducing (MLB) media, (b) T3SS1 inducing (DMEM) media, and (c) T3SS2-inducing (MLB + 0.05% bile salts) media. Resulting biomass was stained with 0.1% crystal violet and measured at absorbance 595 nm. Asterisks indicate statistical significant differences using two-tailed t-test (**P < 0.005, ***P < 0.0005), and error bars show standard deviation (n = 8).
