Stomatogenesis during the formation of the tomite of Hyalophysa chattoni (Hymenostomatida: Ciliophora)

open access: yesEuropean Journal of Protistology, 1997
Summary The functioning oral apparatus of the feeding stage of Hyalophysa chattoni Bradbury, 1966 , arises from pre-existing structures in the tomite that change their form and position during a metamorphosis to the trophont. These structures are the relic of a microstome oral apparatus in the non-feeding tomite.

Effects of different malachite green derivatives and metabolites on the fish ectoparasite, Ichthyophthirius multifiliis, Fouquet 1876 (Hymenostomatida, Ciliophora)

open access: yesEuropean Journal of Protistology, 1997
Summary For the control of fish ectoparasites malachite green is one of the most important fishtherapeutics. This triphenyl-methane dye exists in different derivatives, in the acid pH-range as the coloured salt, in the basic range as the carbinolbase and as the reduced leuco-compound.

Frontonia lynni n. sp., a new marine ciliate (Protozoa, Ciliophora, Hymenostomatida) from Qingdao, China

open access: yesZootaxa, 2005
The morphology, infraciliature and silverline system of a new marine ciliate, Frontonia lynni n. sp., isolated from a sandy beach at Qingdao, China, was investigated using live observation and silver staining methods. The new species is recognized by the combination of the following characters: body about 100–210 x 70–150 µm in vivo, elliptical in ...
