A Pili-Driven Bacterial Turbine

open access: yesFrontiers in Physics, 2022
Work generated by self-propelled bacteria can be harnessed with the help of microdevices. Such nanofabricated microdevices, immersed in a bacterial bath, may exhibit unidirectional rotational or translational motion.

More than propellers: how flagella shape bacterial motility behaviors.

open access: yesCurrent Opinion in Microbiology, 2021
Bacteria use a wide variety of flagellar architectures to navigate their environment. While the iconic run-tumble motility strategy of the peritrichously flagellated Escherichia coli has been well studied, recent work has revealed a variety of new ...

Characterization of C-ring component assembly in flagellar motors from amino acid coevolution [PDF]

open access: yesRoyal Society Open Science, 2018
Bacterial flagellar motility, an important virulence factor, is energized by a rotary motor localized within the flagellar basal body. The rotor module consists of a large framework (the C-ring), composed of the FliG, FliM and FliN proteins.

Effects of Bacterial Motility on Dynamic Succession of Biofilms and Settlement of the Mussel Mytilus coruscus

open access: yesProgress in Fishery Sciences, 2023
To study the regulatory role of marine bacterial motility on biofilm formation and settlement of marine bivalves, this study used the economically important marine mussel Mytilus coruscus as the research target, and investigated the wild-type strain and ...

Bacterial tracking of motile algae [PDF]

open access: yesFEMS Microbiology Ecology, 2003
Abstract We investigated whether bacterial motility and chemotaxis in the ocean enables bacteria to approach and follow microscopic, moving, point sources of nutrients. The turbulent nature of the ocean combined with the imprecision of run and tumble chemotaxis has led to the assumption that marine bacteria cannot cluster around microscopic point ...

Single‐Cell Motility Rapidly Quantifying Heteroresistance in Populations of Escherichia coli and Salmonella typhimurium

open access: yesSmall Science, 2022
Heterogeneous bacterial populations can display increased resistance to external threats, such as exposure to antibiotics. Despite the mounting clinical evidence supporting the importance of bacterial heterogeneity in acute infections, current ...

The interaction of thin-film flow, bacterial swarming and cell differentiation in colonies of Serratia liquefaciens [PDF]

open access: yes, 2000
The rate of expansion of bacterial colonies of S. liquefaciens is investigated in terms of a mathematical model that combines biological as well as hydrodynamic processes. The relative importance of cell differentiation and production of an extracellular

Lohmann Brown Rooster Semen: Intrinsic Bacteria and Their Impact on Sperm Progressive Motility and Seminal Biochemical Parameters—A Preliminary Study

open access: yesStresses, 2023
Semen quality plays a crucial role in poultry production; however, it may be impaired by the presence of numerous bacterial species. This study researched the impact of bacterial contamination of Lohmann brown rooster semen on the biochemical parameters ...

An experimental and computational study of the effect of ActA polarity on the speed of Listeria monocytogenes actin-based motility. [PDF]

open access: yesPLoS Computational Biology, 2009
Listeria monocytogenes is a pathogenic bacterium that moves within infected cells and spreads directly between cells by harnessing the cell's dendritic actin machinery. This motility is dependent on expression of a single bacterial surface protein, ActA,

Effect of Viscosity on Bacterial Motility [PDF]

open access: yesJournal of Bacteriology, 1974
The behavior of a number of motile flagellated bacteria toward viscosity characteristics of their fluid environments was observed. All showed an increase in velocity (micrometers per second) in more viscous solutions. Velocity reached a maximum at a characteristic value, however, and thereafter decreased with higher viscosities ...
