Motility of C. jejuni chemotaxis mutants was impaired, and the motility of flagellar biosynthesis mutants was abolished. Motility was tested by spotting a constant amount of C. jejuni onto soft agar plates (A) and measuring the diameter of the resulting bacterial swarm (B). Shown is the mean ± the standard deviations, with the dotted line indicating the zone of bacterial grown resulting from the spot. The presence and length of the flagellar filament was also determined by staining the flagellum (C). Each measurement is represented by a circle (n > 35 cells measured per isolate) with the mean represented by a bar. Significant differences from wild-type were determined by a Kruskal–Wallis test followed by Dunn’s multiple comparisons test (p < 0.05).
