Motility of three strains of Proteus mirabilis (G9, P11 and PM5C) in liquid suspension under different environmental conditions.
The effect of compounds on the motility of Proteus mirabilis swarmer cells varies from one strain to another. The effect of compounds on the motility of swarmer cells is mainly at higher concentrations than the concentration used to inhibit swarming. Boric acid only affects the motility of strain G9 swarmer cells, whereas sodium deoxycholate prevented the motility of swarmer cells for three strains. Some antibiotics show their effect on the motility of swarmer cells in anaerobic areas, by slowing the movement of swarmer cells, followed by stopping the movement after a period of time or disappearance of the cells. The differentiation between the strains of Proteus species seems to be better in liquid suspension than on the solid medium.
