Spirochete Flagella and Motility [PDF]
Biomolecules, 2020 Spirochetes can be distinguished from other flagellated bacteria by their long, thin, spiral (or wavy) cell bodies and endoflagella that reside within the periplasmic space, designated as periplasmic flagella (PFs). Some members of the spirochetes are pathogenic, including the causative agents of syphilis, Lyme disease, swine dysentery, and ...

Wavelengths of Bacterial Flagella [PDF]
Journal of General Microbiology, 1954 SUMMARY: In sunlight dark-ground microscopy the flagella of a packet of motile sarcina appear as a smooth tail. The tails often stiffen into helices of two different wavelengths, one being twice as long as the other. The short and the long wavelengths are identical in Sarcina ureea and S. agilis. This phenomenon of two wavelengths, one twice as long as

A mathematical model of flagellar gene regulation and construction in Salmonella enterica.
PLoS Computational Biology, 2020 Millions of people worldwide develop foodborne illnesses caused by Salmonella enterica (S. enterica) every year. The pathogenesis of S. enterica depends on flagella, which are appendages that the bacteria use to move through the environment ...

Hydrodynamics with spin in bacterial suspensions [PDF]
Phys. Rev. E 93, 062404 (2016), 2016 We describe a new kind of self-propelling motion of bacteria based on the cooperative action of rotating flagella on the surface of bacteria. Describing the ensemble of rotating flagella in the framework of the hydrodynamics with spin the reciprocal theorem of Stokesian hydrodynamics is generalized accordingly.

Flagellar energetics from high-resolution imaging of beating patterns in tethered mouse sperm
eLife, 2021 We demonstrate a technique for investigating the energetics of flagella or cilia. We record the planar beating of tethered mouse sperm at high resolution. Beating waveforms are reconstructed using proper orthogonal decomposition of the centerline tangent-

eLife, 2021 The canonical chemotaxis network modulates the bias for a particular direction of rotation in the bacterial flagellar motor to help the cell migrate toward favorable chemical environments.

Coordinated Beating of Algal Flagella is Mediated by Basal Coupling [PDF]
Proc. Natl. Acad. Sci. U.S.A. 113(20), E2784-E2793 (2016), 2015 Cilia and flagella often exhibit synchronized behavior; this includes phase locking, as seen in {\it Chlamydomonas}, and metachronal wave formation in the respiratory cilia of higher organisms. Since the observations by Gray and Rothschild of phase synchrony of nearby swimming spermatozoa, it has been a working hypothesis that synchrony arises from ...

Flagellar membranes are rich in raft-forming phospholipids
Biology Open, 2015 The observation that the membranes of flagella are enriched in sterols and sphingolipids has led to the hypothesis that flagella might be enriched in raft-forming lipids.

A Minimal Model of the Hydrodynamical Coupling of Flagella on a Spherical Body with application to Volvox [PDF]
Phys. Rev. E 102, 033114 (2020), 2020 Flagella are hair-like appendages attached to microorganisms that allow the organisms to traverse their fluid environment. The algae Volvox are spherical swimmers with thousands of individual flagella on their surface and their coordination is not fully understood.
