Two-Decade Changes in the Ciliate Assemblage Feeding Pattern Reflect the Reservoir Nutrient Load
DiversityThe perception of the importance of ciliate in freshwater has changed dramatically since the “microbial loop” conceptualisation, reflecting methodological attempts.

Sessile peritrichs (Ciliophora: Peritricha) from freshwater fish in the Transvaal, South Africa [PDF]
, 2017 Sessile peritrichs (Ciliophora: Peritricha) were collected from freshwater fish in lakes, rivers, streams and fish-ponds in the Transvaal, South Africa Nine species of the genus Apiosoma Blanchard, 1885 are described, i.e. seven new species; A.

, 2012 Peritrichs are a diverse, ecologically important ciliate group usually with a complex life cycle. To date, the community of the peritrichs has been investigated by using morphology-based methods such as living observation and silver staining.

Investigating the epibiotic peritrich Zoothamnium intermedium : seasonality and distribution of its relationships with copepods in chesapeake bay (USA) [PDF]
, 2022 Zoothamnium intermedium is an obligate epibiont ciliate on copepods. We examined the life cycle, hostpreferences, and ecological conditions conducive to Z. intermedium presence on copepods inChesapeake Bay. Bacterial abundance in the water column peaked

Multiflagellarity leads to the size-independent swimming speed of peritrichous bacteria
Proceedings of the National Academy of Sciences, 2023 To swim through a viscous fluid, a flagellated bacterium must overcome the fluid drag on its body by rotating a flagellum or a bundle of multiple flagella. Because the drag increases with the size of bacteria, it is expected theoretically that the swimming speed of a bacterium inversely correlates with its body length. Nevertheless,

Predicted Auxiliary Navigation Mechanism of Peritrichously Flagellated Chemotactic Bacteria
PLoS Computational Biology, 2010 Chemotactic movement of Escherichia coli is one of the most thoroughly studied paradigms of simple behavior. Due to significant competitive advantage conferred by chemotaxis and to high evolution rates in bacteria, the chemotaxis system is expected to be strongly optimized.

, 1998 Ciliate communities were studied in the biofilms of three plants with rotating biological contactors (RBCs) over the period of one year. The aims of this study were: (i) to characterize ciliates to species level; (ii) to determine their abundance and ...

The Change from Polar to Peritrichous Flagellation in Chromobacterium spp. [PDF]
Journal of General Microbiology, 1956 SUMMARY: Some strains of Chromobacterium exhibit either polar or mixed polar and peritrichous flagellation according to the conditions of culture. Polar and lateral flagella differ in the site of insertion, the wavelength, ease of staining, and in antigenic composition. Peritrichous flagellation is greatest in young cultures on solid media and is least
