PalC increases swarming motility of S. Typhimurium. (a) S. Typhimurium motility was assayed on swarming plates with increasing concentrations of PalC. The images are representative of one of three technical replicates from one of three biological replicates. (b) Fold change in percentage of agar plate covered by swarming area, comparing PalC added at various concentrations to an untreated PalC negative control. Bars: SD (n = 9, three separate experiments, with three technical replicates per experiment); two asterisks (**) indicates significant difference compared to untreated control, P ≤ 0.01; four asterisks (****) indicates significant difference compared to untreated control, P ≤ 0.0001.
