Bacterial motility: machinery and mechanisms

Nature Reviews Microbiology, 2021
Bacteria have developed a large array of motility mechanisms to exploit available resources and environments. These mechanisms can be broadly classified into swimming in aqueous media and movement over solid surfaces. Swimming motility involves either the rotation of rigid helical filaments through the external medium or gyration of the cell body in ...

Gastrointestinal motility disorders and bacterial overgrowth

Journal of Internal Medicine, 1995
Abstract.Data on the relationship between small intestinal motility, absorption, and nutrition are sparse and incomplete. Yet, impaired motility is considered to be a plausible cause of bacterial overgrowth, which may have deleterious effects on digestion and absorption.

Bacterial Motility and the Bacterial Flagellar Motor

Annual Review of Biophysics and Bioengineering, 1984
Bacteria are exposed to a wide range of environments, some hostile, some benign. Because of their small size and simple structure, their ability to modify their environment is quite limited. The dominant strategy that has evolved, therefore, is selective motion toward environments that enhance the prospects for survival.

Bacterial effect on sperm motility

Urology, 1975
Human semen containing normal number of sperm was exposed to concentrations of Escherichia coli varying from 500 to 10-8 colonies per cubic centimeter. A significant decrease in motility was abserved at 10-6 colonies per cubic centimeter.

Bacterial Flagella and Motility

Nature, 1948
Flagella, and especially bacterial flagella, have been thoroughly investigated during the past decade. Before that they were rather taken for granted. This awakening of interest was largely due to the electron microscope referred to as the EM) which made them more real, and revealed new features, without solving their mysteries. Perhaps also, as Knaysi

Actin-based bacterial motility

Current Opinion in Cell Biology, 1995
Listeria monocytogenes and other bacterial pathogens move in the host cell cytoplasm, propelled by continuous actin assembly at one pole of the bacterium. This actin-based motility requires the presence of the bacterial proteins ActA on L. monocytogenes and IcsA on Shigella flexneri.
