Cells were Gram-negative, chemoheterotrophic, short rod-shaped and motile with a polar flagellum.

Cells of this isolate were Gram-negative, curved rods, motile by means of a polar flagellum.

We report a major deviation from the current paradigm for the regulation of bacterial polar flagellum genes.

Cells of strain ZFJT-2T were Gram-stain-negative, strictly aerobic, rod-shaped and motile by means of a single polar flagellum.

It has been described that Brucella expresses a polar flagellum under certain conditions, but its function is still unknown.
