Anaerocyclidiidae fam. nov. (Oligohymenophorea, Scuticociliatia): A newly recognized major lineage of anaerobic ciliates hosting prokaryotic symbionts

open access: closedEuropean Journal of Protistology, 2023
The research on anaerobic ciliates, to date, has mainly been focused on representatives of obligately anaerobic classes such as Armophorea or Plagiopylea. In this study, we focus on the anaerobic representatives of the subclass Scuticociliatia, members of the class Oligohymenophorea, which is mainly composed of aerobic ciliates.

Transcriptome analysis on chlorpyrifos detoxification in Uronema marinum (Ciliophora, Oligohymenophorea)

open access: closedEnvironmental Science and Pollution Research, 2018
Chlorpyrifos (CPF) pollution has drawn widespread concerns in aquatic environments due to its risks to ecologic system, however, the response mechanisms of ciliates to CPF pollution were poorly studied. In our current work, the degradation of CPF by ciliates and the morphological changes of ciliates after CPF exposure were investigated.

Paramecium (Oligohymenophorea, Ciliophora) diversity in Thailand sheds light on the genus biogeography and reveals new phylogenetic lineages

Journal of Eukaryotic Microbiology, 2023
AbstractParamecium (Ciliophora, Oligohymenophorea) is a good model to study ciliate biogeography. Extensive sampling mainly in northern hemisphere has led to 16 valid morphological species description thus far. However, a majority of hard‐to‐reach regions, including South East Asia, are underinvestigated.

Insights into the origin and evolution of Peritrichia (Oligohymenophorea, Ciliophora) based on analyses of morphology and phylogenomics

Molecular Phylogenetics and Evolution, 2019
Peritrichia is a large and distinctive assemblage of ciliated protists that was first observed by Antonie van Leeuwenhoek over 340 years ago. In the last two decades the evolutionary relationships of this subclass have been increasingly debated as morphological and molecular analyses have generated contrasting conclusions.

Morphology, morphogenesis and phylogeny of Anteglaucoma orientalis n. sp. (Ciliophora, Oligohymenophorea), a freshwater hymenostomatid from northeastern China

European Journal of Protistology, 2021
A new hymenostomatid ciliate, Anteglaucoma orientalis n. sp., isolated from a freshwater pond in Harbin, northeastern China, was investigated using live observation and silver staining methods. Anteglaucoma orientalis is characterized as follows: size in vivo about 50-60 × 30-35 μm; oval body shape; buccal area occupies about 25% of body length; 28-36 ...

Identification of the pathogenic ciliate Pseudocohnilembus persalinus (Oligohymenophorea: Scuticociliatia) by fluorescence in situ hybridization

European Journal of Protistology, 2014
Many scuticociliatid ciliates are regarded as devastating pathogens in aquaculture. Among these, Pseudocohnilembus persalinus is a facultative pathogen that often results in refractory diseases of mariculture fish. Although traditional silver staining methods have been successfully used to identify these ciliates, their identification is hampered by ...
