Figure 6.

(A) Swarming morphology of different strains of V. alginolyticus on NBE carrageenan plates (scale bar, 10 mm), with the top half of the swarming edge highlighted by a dashed line. (B) Phase-contrast image of the swarming front of the slow-swarming strain V. alginolyticus ATCC 17749 highly elongated cells and a lack of a clearly defined front is shown at the start of the time-lapse image series. (C) Whole-image-series temporal variance analysis indicates only low-motion activity compared with fast swarmers. To see this figure in color, go online.
