Tetrahymena, along with other genera of the family Frontoniidae, have been the subject of many scientific investigations concerning problems in protozoan physiology. Unfortunately in many instances, difficulty arises when attempting to identify properly the form that was used in the particular study. Until rather recently, relatively little had been accomplished by way of a comprehensive study ...

In accordance with the International Code of Zoological Nomenclature with the express purpose of clarifying the systematic status of some species, neotypes are designated for Apion atratum Gravenhorst, 1807, Apion chloris Gravenhorst, 1807, Apion longirostre Gravenhorst, 1807 and Apion pilosellum Gravenhorst, 1807. Three new synonymies are proposed: Perapion hydrolapathi (Marsham, 1802) = Apion...

Ciliates use phagocytosis to acquire edible particles. The polymorphic ciliate Tetrahymena vorax appears in two forms ('microstomes' and 'macrostomes'). Transformation of microstomes into macrostomes takes place in the presence of the ciliate Tetrahymena thermophila and enables the macrostome to phagocytose the latter species. The non-specific, constitutive phagocytosis in microstomes thereby c...
