Flow-induced bending of flagella restricts Pseudomonas aeruginosa surface departure [PDF]
mBioShear force associated with flow can bend, twist, or stretch cellular appendages. Bacterial appendages such as flagella can rotate and generate forces. However, it is unclear how environmental and cell-generated forces interact as bacteria associate with

Morphology, Ultrastructure, and Classification of Barthelonids (Metamonada Incertae Sedis): With Descriptions of Microbarthelona Gen. Nov., and Parabarthelona Gen. Nov. [PDF]
J Eukaryot MicrobiolABSTRACT Barthelona is a genus of anaerobic flagellates that forms a sister lineage to Fornicata along with Skoliomonas. Although “Barthelona spp.” are known to separate into three distinct lineages, their detailed morphology has not been examined, and their taxonomic classification is incomplete.

A Revised Understanding of Petalomonad Diversity (Petalomonadida; Euglenida) Enabled by a Cultivation Approach, With Five New Species and Two New Genera. [PDF]
J Eukaryot MicrobiolABSTRACT Euglenids are an important group of free‐living phototrophic, osmotrophic, or phagotrophic protists, with most of the phylogenetic diversity represented by phagotrophs. One major subgroup of phagotrophs is the petalomonads: rigid, often relatively small cells with few pellicle strips (usually 4–8).

Analysis of a Spontaneous Non-Motile and Avirulent Mutant Shows That FliM Is Required for Full Endoflagella Assembly in Leptospira interrogans. [PDF]
PLoS ONE, 2016 Pathogenic Leptospira strains are responsible for leptospirosis, a worldwide emerging zoonotic disease. These spirochetes are unique amongst bacteria because of their corkscrew-like cell morphology and their periplasmic flagella.

MODIFIED STAINING FOR OBSERVATION OF FLAGELLA IN Bacillus amyloliquefaciens BY OPTICAL MICROSCOPY
Tropical and Subtropical Agroecosystems, 2021 Background: Bacillus amyloliquefaciens is a plant growth-promoting rhizobacterium and produces several secondary metabolites with antimicrobial activity. One of its most important morphological characteristics is the presence of flagella.

Gram-Negative Flagella Glycosylation [PDF]
International Journal of Molecular Sciences, 2014 Protein glycosylation had been considered as an eccentricity of a few bacteria. However, through advances in analytical methods and genome sequencing, it is now established that bacteria possess both N-linked and O-linked glycosylation pathways. Both glycosylation pathways can modify multiple proteins, flagellins from Archaea and Eubacteria being one ...

Synthesis of Bacterial Flagella: Chromosomal Synchrony and Flagella Synthesis [PDF]
Journal of Bacteriology, 1969 Synchronous cultures of Bacillus subtilis 168 M were obtained from light-density spores germinated at 46 C and grown at 37 C. This procedure synchronizes both cell division and chromosome replication. The chromosome synchrony was demonstrated by using transformation to measure changes in marker frequency during the ...

iScience, 2019 Summary: Bacteria use flagella, the protein nanofibers on their surface, as a molecular machine to swim. Flagella are polymerized from monomers, flagellins, which can display a peptide by genetic means.

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 ...

Oscillatory movement of a dynein-microtubule complex crosslinked with DNA origami
eLife, 2022 Bending of cilia and flagella occurs when axonemal dynein molecules on one side of the axoneme produce force and move toward the microtubule (MT) minus end.
