To avoid any misunderstanding, it is worth noting here the definite distinction between flagellum (prokaryotic) and cilium (eukaryotic). The two structures only have in common the fact that they are thin mobile protrusions with a precise and stable organization, and also a definite position in the cell (unlike, for example, the pseudopods of eukaryotic

On the uniqueness of the flagellum ofThiobacillus thiooxidans
Antonie van Leeuwenhoek, 1967The flagellum of the obligate chemolithotrophThiobacillus thiooxidans was found to retain its integrity and function under environmental conditions that characterize it as among the most stable of alloplasmatic structures. Although a simple, presumably unsheathed organelle approximately 17 mµ in diameter, it is operationally active at a hydrogen ion ...

CONSIDER a simple homogeneous filament with a wave passing in the direction indicated and suppose that the filament is immersed in water (a). Allow also that the wave is passing along the filament with both an increase in velocity and amplitude and hence an increase in resistance from the water.

Genetic analysis of the bacterial flagellum
Trends in Genetics, 1991Escherichia coli and Salmonella typhimurium invest considerable resources in making flagella, motor organelles that function much like the propellers on a ship. Both classical and molecular genetic studies have begun to reveal how flagellar genes are regulated and how their products build and operate these remarkable devices.

Dynein motors of the Chlamydomonas flagellum
2001Chlamydomonas is a biflagellate unicellular green alga that has proven especially amenable for the analysis of microtubule (MT)-based molecular motors, notably dyneins. These enzymes form the inner and outer arms of the flagellum and are also required for intraflagellar transport.

Inflammasome Recognition and Regulation of the Legionella Flagellum
2016The Gram-negative bacterium Legionella pneumophila colonizes extracellular environmental niches and infects free-living protozoa. Upon inhalation into the human lung, the opportunistic pathogen grows in macrophages and causes a fulminant pneumonia termed Legionnaires' disease. L.
