INTRODUCTION. Bacillus subtilis has two forms of active movement, swimming and swarming motility, that are powered by rotating flagella (73, 113). Swimming motility takes place via individual cells moving in three dimensions of a liquid volume.

Do all bacteria have flagella?

Yes. Flagella are present in both Gram-positive and Gram-negative bacteria. Bacterial flagella are microscopic coiled, hair-like structures, which are involved in the locomotion.

Is Vibrio flagellated?

Many Vibrio spp. are monotrichous with a single, sheathed polar flagellum (e.g., V. cholerae and V. alginolyticus); however, some Vibrios can also be peritrichous or lophotrichous.
