Annual Review of Microbiology, 1977
Flagella are responsible for bacterial motility and chemotaxis. They are subcellular organdies that originate in the membrane of the cell and extend 15-20 µm from the cell surface. The bacterial flagellar system has been studied from a variety of points of view, including as a model for the regulation of organelle formation and morphogenesis, as a ...

Current Opinion in Microbiology, 2006
Flagellar gene networks are fascinating, owing to their complexity - they usually coordinate the expression of more than 40 genes - and particular wiring that elicits temporal expression coupled to organelle morphogenesis. Moreover, many of the lessons learned from flagellar regulation are generally applicable to type III secretion systems.

Bacterial Flagella and Motility
Nature, 1948Flagella, 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

Construction of bacterial flagella
Nature, 1975The flagella of Salmonella can adopt a number of distinct helical forms. This article discusses the design of a subunit which packs to give a helical filament. Polymorphism is explained by small changes in the geometry of the subunit.

The Quarterly Review of Biology, 1980
Most bacterial movement is the result of the action of a subcellular structure, the flagellar organelle. Bacterial flagella propel the cell by rotating, and this rotation is regulated in response to information transmitted by chemoreceptors on the surface of the cell. Rotation is driven by a motor anchored in the cell membrane.

Disintegration of flagella by acid
Archives of Biochemistry and Biophysics, 1965Abstract During the disintegration of flagella from cells of Proteus vulgaris, hydrogen ions are taken up; thus one can determine the rate of this disintegration by measuring the number of hydrogen ions consumed at a constant pH. The rate of disintegration was studied in this manner over the pH range 2.5–3.4.

Undulipodia, flagella and cilia
Biosystems, 1980The term flagella is ambiguous. It refers to bacterial structures composed of flagellin protein and to eukaryotic structures composed of microtubule proteins and ATPase (tubulin and dynein). The fact that cilia are nearly identical to eukaryotic flagella and have nothing in common with prokaryotic flagella is not apparent from the terminology.

Journal of Experimental Biology, 1967
ABSTRACT Equations are derived for the propulsive velocities and power dissipation of undulating hispid flagella. The observed rates of movement of water around the flagella of two chrysomonad flagellates and the translational speed of Ochromonas malhamensis agree closely with values calculated if it is assumed that the flagellar ...

Flagella and bacterial pathogenicity
Journal of Basic Microbiology, 2012AbstractAs locomotive organelles, flagella allow bacteria to move toward favorable environments. A flagellum consists of three parts: the basal structure (rotary motor), the hook (universal joint), and the filament (helical propeller). For ages, flagella have been generally regarded as important virulence factors, mainly because of their motility ...
