5S and 5.8S ribosomal RNA evolution in the suborder tetrahymenina (Ciliophora: Hymenostomatida)

Journal of Molecular Evolution, 1985
The nucleotide sequences of the 5S and 5.8S rRNAs of eight strains of tetrahymenine ciliates have been determined. The sequences indicate a clear distinction between Tetrahymena paravorax and its suggested conspecific T. vorax, but leave the taxonomic distinction between T. vorax and T. leucophrys in doubt. The rRNA sequences of six Tetrahymena species

[Ophryoglena faurei n. sp. (Ciliata, Hymenostomatida, Ophryoglenidae). Reproduction cycles].

The Journal of protozoology, 1998
SYNOPSIS. Ophryoglena faurei is a large ophryoglena distinguished by a long theront, either cylindrical or pearshaped, by a very bulky, often lengthened trophont and by a voluminous tomont.During fasting, physiological changes cause a secondary and temporary encystment of the theront which lasts for 15–18 days at 18°C.

Reproducing Singlets with an Inverted Oral Apparatus in Glaucoma scintillans (Ciliophora, Hymenostomatida)¹

The Journal of Protozoology, 1985
A fragment with only an abnormal oral apparatus (OA) was obtained by operation from a doublet of Glaucoma scintillans possessing one normal and one abnormal OA. This singlet could reproduce and produced a cell line. Singlets frequently possessed an inverted OA, whose antero‐posterior axis was rotated 180°.

Salinity acclimation of euryhaline infusoria Paramecium calkinski and P. woodruffi (Ciliophora, Hymenostomatida)

, 1999
The upper levels of salinity tolerance (assumed as 100% survival) after 48 h exposition were 12 and 13‰ in two the White Sea P. calkinski clones and 18‰ in one P. woodruffi clone from the Barents Sea coast. After carrying infusoria from the control medium (practically fresh water) into media of 8.5 and 12‰ salinity (P. calkinski) and 8.5 and 17(20)‰ (P.

Miamiensis avidus n. g., n. sp., a Marine Facultative Parasite in the Ciliate Order Hymenostomatida*

The Journal of Protozoology, 1964
SYNOPSIS. Miamiensis avidus n. g., n. sp., a marine facultative parasite, is described. Morphological studies were made on specimens treated with the Chatton‐Lwoff silver impregnation technique and living material was examined with phase microscopy.

Treatment of fish parasites

Parasitology Research, 1992
For systemic therapy against trophozoites of the skin-inhabiting stage of Ichthyophthirius multifiliis in ornamental fish, the latter were fed medicated food flakes containing malachite green once daily for 1-11 days ad libitum. Naturally or artificially infected cardinal tetras (Paracheirodon axelrodi), blue gouramis (Trichogaster trichopterus), or ...

Paranophrys marina n. g., n. sp., a New Ciliate Associated with a Hydroid from the Northeast Pacific (Ciliata: Hymenostomatida)*

The Journal of Protozoology, 1965
SYNOPSIS. The ciliate, Paranophrys marina n. g., n. sp., is described from a marine hydroid, Plumularia sp., collected in the San Juan Archipelago, Washington. Morphological studies were made on specimens treated with the Chatton‐Lwoff silver impregnation technique.
