Fig. 2: Surface colonization on pillars by P. aeruginosa is determined by bacterial motility.
From: The effect of flow on swimming bacteria controls the initial colonization of curved surfaces
Intensity distribution of the fluorescent signal from GFP-tagged motile (PA14 wt, a) and nonmotile (PA14 flgE, b; PA14 motB, c) P. aeruginosa cells attached to a 100-µm pillar after 5 h flow at a rescaled flow velocity of U/V = 6.6. d, e Angular distribution of the normalized attachment density of bacteria on the pillar obtained with a mathematical model for motile (d) and nonmotile (e) cells for the same flow rate and pillar dimension as a–c. f Integrated intensity, IIN obtained for the motile (wt) and nonmotile (flgE, motB) strains from the images in a–c. Error bars correspond to the standard error of the mean.
