Fig 3. Movement of the X. fastidiosa PD1671 mutant in microfluidic chambers.

Twitching movement speed of wild-type X. fastidiosa Temecula 1, PD1671 mutant, and complemented PD1671 mutant (PD1671-C) cells in microfluidic flow chambers. Values shown are means and standard errors from three independent experiments. Letters above bars indicate significant differences by Kruskal-Wallis test and means were separated by the Kruskal-Wallis all pairwise comparison test (P = 0.02)
