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.

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.

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

Apofrontonia dohrni, a new peniculine ciliate, was discovered in a slightly brackish water sample from Mediterranean coastline puddle in Naples, Italy. Its morphology was studied in vivo, in silver‐ and Feulgen‐stained preparations, as well as at the scanning electron microscope; 18S rRNA gene sequence was also determined. The species is characterized

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 ...

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 ...

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.

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 ciliate genus Malacophrys has been incertae sedis for more than 50 years in what is now subphylum Intramacronucleata, provisionally assigned to three different classes by various authors. Of the three species included in the genus, M. sphagni and the type species, Malacophrys rotans, have not been studied by modern methods and M.
