Two hypotrichous ciliates from China were investigated. The common oxytrichid species Tetmemena pustulata (Müller, 1786) Eigner, 1999, isolated from the estuary of the Pearl River in southern China, was investigated with emphasis on its living morphology and infraciliature. Tetmemena pustulata is characterized as follows: body elliptical to obovoid in(More)
The morphology and infraciliature of two novel marine scuticociliates, Metanophrys orientalis spec. nov. and Uronemella sinensis spec. nov., collected from sandy beaches at Qingdao, China, were investigated using live observation and protargol-staining methods. Metanophrys orientalis spec. nov. is distinguished by the following characteristics: marine(More)
The morphology of two freshwater urostylid species, Neourostylopsis flava spec. nov. and Pseudourostyla subtropicaChen et al., 2014, isolated from freshwater ponds in northern and southern China, respectively, was investigated following examination of specimens in vivo and following protargol staining. Neourostylopsis flava spec. nov. is distinguished from(More)
The morphology and infraciliature of three Frontonia species, F. subtropica spec. nov., F. canadensis Roque and Puytorac, 1972, and F. magna Fan et al., 2011, isolated from coastal waters in southern China sea, were investigated using living observation and silver impregnation methods. Frontonia subtropica spec. nov. is recognized by the combination of the(More)
Certain ciliates of the subclass Scuticociliatia (scuticociliates) are facultative parasites of fishes in which they cause a suite of diseases collectively termed scuticociliatosis. Hitherto, comparatively little was known about genetics and genomics of scuticociliates or the mechanism of scuticociliatosis. In this study, a laboratory culture of the(More)
Epidermal growth factor (EGF) induces proliferation of epidermal and epithelial tissues in mammals. However, the effect of EGF on the single-celled eukaryotes is not well characterized, especially in the protists. Ciliates, an important group of protists, are well characterized as both pollution indicators and model organisms for research. Stylonychia(More)
This study investigates the effects of copper and mercury on growth rate, chlorophyll a content, superoxide dismutase (SOD) activity, SOD mRNA gene expression, and frustule morphology of the benthic freshwater diatom Halamphora veneta (Kützing) Levkov and the potential utility of each for toxicity assessment in aquatic habitats. Results showed the(More)
The protargol staining method has proved to be indispensable for revealing the cellular structures of a variety of protozoa, especially the flagellates and ciliates. Protargol provides permanent stains of a variety of cellular structures: nuclei, extrusomes, basal bodies, and microfilamentous constituents of cells. Together with the older silver nitrate(More)
The morphology and infraciliature of one freshwater ciliate, Cyclidium sinicum spec. nov., isolated from a farmland pond in Harbin, northeastern China, was investigated using living observation and silver staining methods. Cyclidium sinicum spec. nov. is distinguished by the following features: body approximately 20-25 × 10-15 μm in vivo; buccal field about(More)
The morphology, infraciliature and SSU rDNA sequence of a new freshwater hymenostomatid ciliate, Anteglaucoma harbinensis gen. nov., spec. nov., collected from a farmland pond in Harbin, China, were investigated. The new genus Anteglaucoma is characterized as follows: small to medium-sized Glaucomidae with oral apparatus in anterior one-third of cell;(More)
