Bacterial motility detected on agar plates.

<p>Appropriately diluted bacteria were grown overnight at 37°C on LB plates containing 0.6% or 0.27% agar. No differences of bacterial colonies are seen in panel (A) (0.6% agar) whereas panel B (0.27% agar) shows that the parental BW25113 gave strong swarming activity that is not seen with the <i>ΔfliG</i> mutant.
