Scuticociliates and hymenostomes are two groups of the ciliate class Oligohymenophorea, a diverse clade that includes two model genera, Tetrahymena and Paramecium, which have been intensively studied due to their ease of culture and their amenability to a wide range of biochemical and genetic investigations.

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 pentaurelia is one of 15 known sibling species of the Paramecium aurelia complex. It is recognized as a species showing no intra-specific differentiation on the basis of molecular fingerprint analyses, whereas the majority of other species are polymorphic. This study aimed at assessing genetic polymorphism within P. pentaurelia including new

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 ...

New Paramecium (Ciliophora, Oligohymenophorea) congeners shape our view on its biodiversity
Organisms Diversity & Evolution, 2015Paramecium 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 ...

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.

ABSTRACT. Phylogenetic relationships among peritrich ciliates remain unclear in spite of recent progress. To expand the analyses performed in previous studies, and to statistically test hypotheses of monophyly, we analyzed a broad sample of 18s rRNA sequences (including 15 peritrich genera), applying a conservative alignment strategy and several ...

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.

Relationships among members of the ciliate subclass Scuticociliatia (Ciliophora, Oligohymenophorea) are largely unresolved. Phylogenetic studies of its orders Pleuronematida and Loxocephalida were initially based on small subunit ribosomal RNA gene (SSU-rDNA) analyses of a limited number of taxa.
