We have used small subunit rRNA gene sequences to determine the phylogenetic relationships of species in three genera of endosymbiotic ciliates. We have confirmed that the astome Anoplophrya marylandensis is related to ciliates in the Class Oligohyme

Resume Selon leur degre d'evolution, les opalines possedent, a l'etat trophique, de deux a un tres grand nombre de noyaux tous genetiquement identiques. Ce ne sont donc pas des protistes typiques mais des syncitiums plus ou moins complexes. Elles se

The morphology and cytology of two new opalinid species were studied using silver impregnation and fixation, which preserves the microfibrils. Both species, commensal on Acanthixalus spinosus, are host-specific. Light microscopy showed the existence

Summary The cytoskeleton of Cepedea sudafricana was studied by silver staining according to the method of FERNANDEZ-GALIANO 1976) and by electron microscopy after fixation, which preserves the microfibrils better.The fibrillar cytoskeleton of this sp

Summary: From a morphological and morphometrical study of ciliates of genus Prosicuophora which is a commensal of the African toads, Buto regularis and B. maculatus , it appears that two species have to be distinguished. They are P. basoglui de Puyto

Summary At certain phases of the life cycle of Protoopalina pseudonutti silver impregnation according to the technique of Fernandez-Galiano reveals a large axial fibrillar complex which divides into numerous lateral branches linked to the falcular zo

Summary Protoopalina drachi Tuzet & Knoepfler 1968 found in the african frog Ptychadena maccarthensis presents general ultrastructural features of Opalinids: cortical folds substained by longitudinal microtubules associated by bouble strands and inse

Five multinucleate opalinids from Canada and Cameroon, Africa, commensal in anuran amphibians, are redescribed. The relative size of the falx and the presence or absence of a posterior zone of convergence of kineties in silver-impregnated specimens s

Morphology and infraciliature of samples of at least 22 different opalinid populations were investigated using the silver impregnation method of Fernandez-Galiano (1976). Three genera of opalinids: Protoopalina, Cepedea and Opalina were identified in

Using pyridinated ammoniacal silver nitrate and Protargol impregnation, the author characterized the infraciliature of two nyctotheran ciliates from the gut of anuran Amphibia from Quebec. On this basis, he proposes a morphological redescription and
