Flagellar Motility and Structure in the Hyperthermoacidophilic Archaeon Sulfolobus solfataricus [PDF]

, 2007
Flagellation in archaea is widespread and is involved in swimming motility. Here, we demonstrate that the structural flagellin gene from the crenarchaeaon Sulfolobus solfataricus is highly expressed in stationary-phase-grown cells and under unfavorable ...

Interspecies interactions induce exploratory motility in Pseudomonas aeruginosa

eLife, 2019
Microbes often live in multispecies communities where interactions among community members impact both the individual constituents and the surrounding environment. Here, we developed a system to visualize interspecies behaviors at initial encounters.

The HP0256 gene product is involved in motility and cell envelope architecture of Helicobacter pylori [PDF]

, 2010
Background Helicobacter pylori is the causative agent for gastritis, and peptic and duodenal ulcers. The bacterium displays 5-6 polar sheathed flagella that are essential for colonisation and persistence in the gastric mucosa.

Novel cyclic di-GMP effectors of the YajQ protein family control bacterial virulence [PDF]

, 2014
Bis-(3',5') cyclic di-guanylate (cyclic di-GMP) is a key bacterial second messenger that is implicated in the regulation of many critical processes that include motility, biofilm formation and virulence. Cyclic di-GMP influences diverse functions through

Machine learning-based motion tracking reveals an inverse correlation between adhesivity and surface motility of the leptospirosis spirochete

Nature Communications, 2023
Bacterial motility is often a crucial virulence factor for pathogenic species. A common approach to study bacterial motility is fluorescent labeling, which allows detection of individual bacterial cells in a population or in host tissues.

Production and Characterization of Motile and Chemotactic Bacterial Minicells [PDF]

ACS Synthetic Biology, 2021
Minicells are nanosized membrane vesicles produced by bacteria. Minicells are chromosome-free but contain cellular biosynthetic and metabolic machinery, and they are robust due to the protection provided by the bacterial cell envelope, which makes them potentially highly attractive in biomedical applications. However, the applicability of minicells and

A Simple Quantitative Assay for Bacterial Motility [PDF]

Journal of General Microbiology, 1977
It is argued that the average motility of bacterial populations should be identified with a diffusivity parameter. A simple capillary assay for quantifying this parameter is described, and some results obtained by using this procedure are presented. It is concluded that the assay combine speed and simplicity of operation with sufficient accuracy to ...

Functional characterization of the transcription factor YjjQ in Escherichia coli [PDF]

, 2013
YjjQ is a FixJ/NarL‐type transcriptional regulator conserved in commensal and various pathogenic bacteria such as enterohaemorrhagic Escherichia coli (EHEC), uropathogenic E. coli (UPEC) as well as Citrobacter and Enterobacter.
