Ophryoglena mugardi n. sp. (Ciliata Hymenostomatida Ophryoglenidae). Cycles de reproduction*

The Journal of Protozoology, 1962
SYNOPSIS. Ophryoglena mugardi is an Ophryoglena of medium size characterized by its spindle‐shaped and bimicronuclear theront, by its rather bulky trophont and by its physiological reproductive cycle. During starvation its physiological evolution causes a secondary and temporary encystment of the theront lasting 6 or 7 days (at 18°C). The ultimate re‐

Tetrahymena dimorpha sp.nov. (Hymenostomatida: Tetrahymenidae), a new ciliate parasite of Simuliidae (Diptera) with potential as a model for the study of ciliate morphogenesis

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1983
Abstract A new species of hymenostome ciliate, Tetrahymena dimorpha sp.nov., is described. This ciliate occurs as a parasite in the haemocoel of larval, pupal and adult Simuliidae (Diptera). In larval hosts the total number of parasites never exceeds about 240 and the infection is benign. Within larval hosts the ciliates are large and

A Paradigm for the study of insect-ciliate Relationships: Tetrahymena sialidos sp. nov. (Hymenostomatida: Tetrahymenidae), Parasite of Larval Sialis Lutaria (Linn.) (Megaloptera: Sialidae)

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1985
Abstract A new species of hymenostome ciliate, Tetrahymena sialidos sp.nov., is described and proposed as a model for studies upon insect-ciliate interactions. This ciliate occurs as a parasite in the haemocoel of larval Sialis lutaria (Megaloptera) and exhibits field and laboratory characteristics favourable for two particular areas ...

Interactions between Paramecium bursaria (Protozoa, Ciliophora, Hymenostomatida) and their nuclear symbionts: I. Phenomenon of symbiogenic lysis of the bacterium Holospora acuminata.

European journal of protistology, 2012
In experimental infections the phenomenon of the lysis of symbiotic bacteria (SB) in the host-cell nucleus was discovered for the first time. Light optical investigations were made of 308 possible combinations of experimental infections of 44 clones of originally symbiont-free Paramecium bursaria by 7 strains of SB Holospora acuminata of different ...
