FIG. 4.
Quantification of the initial bacterial attachment. Bacteria attached to the liquid-air interface of the glass coverslips at 2 and 4 h after inoculation of the wild-type (wt) and Δbps strains were counted under a light microscope. For DspB-treated samples, the strains were cultured overnight in presence of DspB, followed by inoculation of the fresh medium with the respective pretreated strains. Data are averages of at least four random 50-μm2 regions of the coverslip. The experiment was performed in duplicate. Error bars, standard deviations.
