Bending Moments in Free-Swimming Flagella [PDF]
The bending of a flagellum, such as the flagellum which forms the tail of a sea-urchin spermatozoon, is the result of active mechanochemical processes occurring within the flagellum itself, which cause it to bend actively throughout its length (Gray ...

Proximity-Dependent Biotinylation and Identification of Flagellar Proteins in Trypanosoma cruzi
The flagellated kinetoplastid protozoan and causative agent of human Chagas disease, Trypanosoma cruzi, inhabits both invertebrate and mammalian hosts over the course of its complex life cycle. In these disparate environments, T.

The Periplasmic Flagellum of Spirochetes
Although spirochete periplasmic flagella have many features similar to typical bacterial flagella, they are unique in their structure and internal periplasmic location. This location provides advantages for pathogenic spirochetes to enter and to adapt in the appropriate host, and to penetrate through matrices that inhibit the motility of most other ...

Flagella bending affects macroscopic properties of bacterial suspensions
To survive in harsh conditions, motile bacteria swim in complex environment and respond to the surrounding flow. Here we develop a PDE model describing how the flagella bending affects macroscopic properties of bacterial suspensions.

Isolation of the Buchnera aphidicola flagellum basal body complexes from the Buchnera membrane.
Buchnera aphidicola is an intracellular bacterial symbiont of aphids and maintains a small genome of only 600 kbps. Buchnera is thought to maintain only genes relevant to the symbiosis with its aphid host.

Trypanosoma brucei possesses a motile flagellum that determines cell morphology and the cell division plane. Inheritance of the newly assembled flagellum during the cell cycle is controlled by the Polo-like kinase homolog TbPLK, which also regulates ...

Irradiation of Sperm Tails by Laser Microbeam [PDF]
1. Sea-urchin and starfish sperm tails were irradiated at pre-selected points along the flagellum and at pre-selected phases of the beat cycle by means of a pulsed ruby laser microbeam. Multiple-exposure dark-field photomicrographs were taken immediately

In-phase and anti-phase flagellar synchronization by waveform compliance and basal coupling
We present a theory of flagellar synchronization in the green alga Chlamydomonas , using full treatment of flagellar hydrodynamics and measured beat patterns.

Direction of flagellum beat propagation is controlled by proximal/distal outer dynein arm asymmetry
Significance The motile flagellum/cilium is found across eukaryotic life, and it performs critical functions in many organisms including humans. A fundamental requirement for a motile flagellum is that it must undergo the appropriate waveform for its ...

Modelling the Mechanics and Hydrodynamics of Swimming E. coli
The swimming properties of an E. coli-type model bacterium are investigated by mesoscale hy- drodynamic simulations, combining molecular dynamics simulations of the bacterium with the multiparticle particle collision dynamics method for the embedding ...
