Flagella bending affects macroscopic properties of bacterial suspensions
, 2016 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.

Hydrodynamic synchronization of flagellar oscillators [PDF]
, 2016 We survey the theory synchronization in collections of noisy oscillators. This framework is applied to flagellar synchronization by hydrodynamic interactions.

Bacterial swarmer cells in confinement: A mesoscale hydrodynamic simulation study [PDF]
, 2016 A wide spectrum of Peritrichous bacteria undergo considerable physiological changes when they are inoculated onto nutrition-rich surfaces and exhibit a rapid and collective migration denoted as swarming.

Zipping and Entanglement in Flagellar Bundle of E. Coli: Role of Motile Cell Body
, 2015 The course of a peritrichous bacterium such as E. coli crucially depends on the level of synchronization and self-organization of several rotating flagella. However, the rotation of each flagellum generates counter body movements which in turn affect the

Calcium-induced asymmetrical beating of triton-demembranated sea urchin sperm flagella [PDF]
, 1979 Asymmetrical bending waves can be obtained by reactivating demembranated sea urchin spermatozoa at high Ca2+ concentrations. Moving-film flash photography shows that asymmetrical flagellar bending waves are associated with premature termination of the ...

A PAS Domain-Containing Regulator Controls Flagella-Flagella Interactions in Campylobacter jejuni
Frontiers in Microbiology, 2015 The bipolar flagella of the foodborne bacterial pathogen Campylobacter jejuni confermotility, which is essential for virulence. The flagella of C. jejuni are posttranslationallymodified, but how this process is controlled is not well understood.

Frontiers in Microbiology, 2022 The anaerobic bacterium Clostridioides difficile represents one of the most problematic pathogens, especially in hospitals. Dysbiosis has been proven to largely reduce colonization resistance against this intestinal pathogen. The beneficial effect of the

Effects of antibodies against dynein and tubulin on the stiffness of flagellar axonemes [PDF]
, 1981 Antidynein antibodies, previously shown to inhibit flagellar oscillation and active sliding of axonemal microtubules, increase the bending resistance of axonemes measured under relaxing conditions, but not the bending resistance of axonemes measured ...

Beating patterns of filaments in viscoelastic fluids
, 2008 Many swimming microorganisms, such as bacteria and sperm, use flexible flagella to move through viscoelastic media in their natural environments. In this paper we address the effects a viscoelastic fluid has on the motion and beating patterns of elastic ...
