Swarming Assays

Caption: Part 1: Swarming by the ancestral (wild type) strain, Pseudomonas aeruginosa PA14, shows the typical branching pattern of swarming colonies. Part 2: Swarming by a hyperswarmer mutant, clone #10, shows a very distinct phenotype without branching. Part 3: Repulsion assay for hyperswarmer clone #5 shows that the colony is still repelled by the presence of a immotile strain (flgK-), although less than the wild type or other hyperswarmer clones.
