Motility Clause Samples

Motility. To gain entry to the urinary tract, P. mirabilis must utilize a form of motility that allows it to migrate across the catheter surface. The form of motility P. mirabilis utilizes for movement over catheters is swarming motility, a population-dependent form of surface migration where highly flagellated and elongated swarmer cells form rafts to traverse solid surfaces (16, 17). Following contact with a solid surface, such as a catheter, vegetative, short-rod shaped P. mirabilis cells undergo a process known as differentiation into highly flagellated, elongated, multinucleate swarmer cells (18). Consolidation is the process by which swarmer cells revert back to vegetative cells following a period of migration (16). Swarming motility is covered in detail later in this chapter.
