Phylogeny of Novel Naked Filose and Reticulose Cercozoa: Granofilosea cl. n. and Proteomyxidea Revised

Protist, 2009
Naked filose and reticulose protozoa were long lumped as proteomyxids or left outside higher groups. We cultivated eight naked filose or reticulose strains, did light microscopy, 18S rDNA sequencing and phylogeny (showing all are Cercozoa), and sequenced 80 environmental 18S-types.

Stramenopiles and Cercozoa dominate the heterotrophic protist community of biological soil crusts irrespective of edaphic factors

, 2020
Biological soil crusts (biocrusts) are terrestrial micro-habitats distributed in drylands and also in temperate coastal dunes. Biocrusts harbor phototrophic and heterotrophic microorganisms in the upper soil layer, which fulfil important ecological ...

Morphology and Phylogeny of Sainouron acronematica sp. n. and the Ultrastructural Unity of Cercozoa

Protist, 2008
Sainouron are soil zooflagellates of obscure taxonomy. We studied the ultrastructure of S. acronematica sp. n. and sequenced its extremely divergent 18S rDNA and that of Cholamonas cyrtodiopsidis (here grouped as new family Sainouridae) to clarify their phylogeny.

Structure of filose amoeba Rhogostoma minus Belar 1921 (Cryomonadida, Cercozoa) cell

Inland Water Biology, 2012
The structure of the unicellular cell of filose amoeba, Rhogostoma minus Belar, 1921, is studied. Zoospores, cysts, and multinuclear plasmodia have not been found. The cell is covered by a thin shell made out of organic matter. Narrow and branched pseudopodia arise from the pseudostome.

A novel paramyxean parasite, Marteilia tapetis sp. nov. (Cercozoa) infecting the digestive gland of Manila clam Ruditapes philippinarum from the southeast coast of Korea.

Journal of Invertebrate Pathology, 2019
Paramyxean parasites in the genus Marteilia deteriorate digestive tissues of the host organisms, resulting in mortality of oysters, cockles, and mussels. Most reports of infection by Marteilia spp.

Házas amőbák (Amoebozoa: Arcellinida és Cercozoa: Filosea) Gyűrűfű térségében

Natura Somogyiensis, 2009
The purpose of this study was to extend our knowledge of the testate amoebae in Hungary. Soil and to a lesser extent sediment samples were investigated in the frame of the 2. Biodiversity Day in Hungary, organized in a 1 km2 area around the abandoned south-transdanubian village Gyűrűfű in the Zselic Hills.

SSU rDNA Phylogeny Indicates the Scale-lacking Trivalvulariida ord. nov. as a Sister Group to the Euglyphida (Cercozoa, Rhizaria).

Protist, 2019
The testate amoeba Leptogromia operculata was described by Valkanov in 1970 from marine waters. We re-discovered this species in brackish water along the North Sea in the Netherlands.

Mikrocytos mytilicoli n.sp. (Cercozoa, Mikrocytida, Mikrocytiidae) infecting the copepod Mytilicola intestinalis (Arthropoda, Cyclopoida, Mytilicolidae), a symbiont of Mytilus galloprovincialis in Galicia (NW Spain).

Journal of Invertebrate Pathology, 2020
During a histopathological survey of Mytilus galloprovincialis in Galicia (NW Spain), microcells were observed infecting several organs of the symbiont copepod Mytilicola intestinalis.

Eat Prey, Love? Diverse Soil Cercozoa Tell Tales of Climate Change

Microbe Magazine, 2016
The enormous species diversity of Cercozoa, important soil protozoans that feed on bacteria there, might provide a means for following climate change trends, according to Flemming Ekelund at the University of Copenhagen in Denmark and his collaborators.

An Orphan Protist Quadricilia rotundata Finally Finds Its Phylogenetic Home in Cercozoa

Journal of Eukaryotic Microbiology, 2018
AbstractQuadricilia rotundata is a heterotrophic flagellate with four flagella. However, because this species has no clear morphological characteristics or molecular data affiliating it with any known group, Q. rotundata has been treated as a protist incertae sedis, for a long time. Here, we established a clonal culture of Q.
