We isolated an encysted ciliate from a geothermal field in Iceland. The morphological features of this isolate fit the descriptions of Dexiotricha colpidiopsis Kahl, 1926) Jankowski, 1964 very well.

Nuclear events during conjugation in the poorly studied model ciliate Paramecium jenningsi [PDF]
Ciliated protists are highly differentiated unicellular eukaryotes that possess special sexual processes (conjugation and autogamy) that rely on their unique nuclear dimorphism, i.e., the presence of both a germline micronucleus (MIC) and a somatic ...

Phylogenetic Relationships of the Subclass Peritrichia (Oligohymenophorea, Ciliophora) Inferred from Small Subunit rRNA Gene Sequences1 [PDF]
ABSTRACT. The phylogenetic relationships among peritrichs remain unresolved. In this study, the complete small subunit rRNA (SSrRNA) gene sequences of seven species (Epistylis galea, Campanella umbellaria, Carchesium polypinum, Zoothamnium arbuscula, Vaginicola crystallina, Ophrydium versatile, and Opercularia microdiscum) were determined.

The neotypification of Frontonia vernalis (Ehrenberg, 1833) Ehrenberg, 1838 and the description of Frontonia paravernalis sp. nov. trigger a critical revision of frontoniid systematics [PDF]
Background: Among Oligohymenophorea (Ciliophora, Alveolata) the subclass Peniculia stands as one of the most well-known groups. Frontonia is the largest genus of Peniculia, and its representatives are spread in any type of water bodies as well as in ...

New Paramecium (Ciliophora, Oligohymenophorea) congeners shape our view on its biodiversity
Paramecium is one of the best known and most intensely studied ciliate genera. It currently comprises 18 morphospecies including the P. aurelia complex of 15 sibling species. Here, we describe the new morphospecies Paramecium buetschlii sp. nov. from a freshwater pool in Norway, featuring unusual combinations of morphological characters and a high ...

The morphology and infraciliature of a new oligohymenophorean ciliate, Cinetochilum ovale n. sp., isolated from the littoral sediment of the Bohai Sea, northern China, were investigated using live observations and silver impregnations. This new species as follows: size about 20–30 × 15–25 µm in vivo, body oval in outline, with 12–13 bipolar somatic ...

Paramecium tredecaurelia: A Unique Non-Polymorphic Species of the P. aurelia spp. Complex (Oligohymenophorea, Ciliophora) [PDF]
New stands of Paramecium tredecaurelia, a rare species of the P. aurelia spp. complex, were identified in Thailand and Madagascar on the basis of mating reactions and molecular markers (rDNA and mtDNA).

Alpha-Tubulin and Small Subunit rRNA Phylogenies of Peritrichs Are Congruent and Do Not Support the Clustering of Mobilids and Sessilids (Ciliophora, Oligohymenophorea) [PDF]
Peritrich ciliates have been traditionally subdivided into two orders, Sessilida and Mobilida within the subclass Peritrichia. However, all the existing small subunit (SSU) rRNA phylogenetic trees showed that the sessilids and mobilids did not branch ...

“Candidatus Sonnebornia yantaiensis”, a member of candidate division OD1, as intracellular bacteria of the ciliated protist Paramecium bursaria (Ciliophora, Oligohymenophorea) [PDF]
An intracellular bacterium was discovered in an isolate of Paramecium bursaria from a freshwater pond in Yantai, China. The bacteria were abundant and exclusively found in the cytoplasm of the host which, along with the green alga Chlorella, formed a three-partner consortium that could survive in pure water for at least one week.
