Host-induced spermidine production in motile Pseudomonas aeruginosa triggers phagocytic uptake
eLife, 2020 Exploring the complexity of host–pathogen communication is vital to understand why microbes persist within a host, while others are cleared. Here, we employed a dual-sequencing approach to unravel conversational turn-taking of dynamic host–pathogen ...

Swimming of bacterium \textit{Bacillus subtilis} with multiple bundles of flagella [PDF]
Soft matter 2019, 2019 We characterize the bundle properties for three different strains of \textit{B. subtilis} bacteria with various numbers of flagella. Our study reveals that, surprisingly, the number of bundles is independent of the number of flagella, and the formation of three bundles is always the most frequent case.

The chiral beat of algal flagella: force and torque via imaging [PDF]
arXiv, 2022 Flagella allow eukaryotic cells to move and pump fluid. We present the first three-dimensional, time-resolved imaging of the flagellar waveform of Chlamydomonas reinhardtii, a model alga found in fresh water. During the power stroke, we find that the flagella show rotational symmetry about the cell's centreline, but during the recovery stroke they ...

Frontiers in Microbiology, 2018 Listeria monocytogenes is a food-associated bacterium that is responsible for food-related illnesses worldwide. In the L. monocytogenes EGD-e genome, FlhB, FliM, and FliY (encoded by lmo0679, lmo0699, and lmo0700, respectively) are annotated as putative ...

Frontiers in Cellular and Infection Microbiology, 2021 Trypanosomatids have a cytoskeleton arrangement that is simpler than what is found in most eukaryotic cells. However, it is precisely organized and constituted by stable microtubules.

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 ...

Microorganisms, 2022 The flagella of enteropathogenic Escherichia coli (EPEC) O127:H6 E2348/69 mediate adherence to host proteins and epithelial cells. What environmental and nutritional signals trigger or down-regulate flagella expression in EPEC are largely unknown.

, 1999 The bacterial flagellum is probably the most complex organelle found in bacteria. Although the ribosome may be made of slightly more subunits, the bacterial flagellum is a more organized and complex structure. The limited number of flagella must be targeted to the correct place on the cell membrane and a structure with cytoplasmic, cytoplasmic membrane,

Isolation of Leishmania Promastigote Flagella [PDF]
, 2020 Eukaryotic flagella are conserved multifunctional organelles with roles in motility, intercellular interactions, and signal transduction. Leishmania possess a single flagellum at all stages of their life cycle. Flagella of promastigote forms in the fly are long and motile, with a canonical 9 + 2 microtubule axoneme and an extra-axonemal paraflagellar ...

Swarm behavior of self-propelled rods and swimming flagella [PDF]
Phys. Rev. E 82, 031904 (2010), 2010 Systems of self-propelled particles are known for their tendency to aggregate and to display swarm behavior. We investigate two model systems, self-propelled rods interacting via volume exclusion, and sinusoidally-beating flagella embedded in a fluid with hydrodynamic interactions.
