The structure of archamoeba Pelomyxa paradoxa Penard, 1902—an organism that has been reisolated for the first time since its redescription—has been studied at the light and electron-microscopy levels. During movement, pelomyxa have a cigarlike body shape, at the sides of which conical and fingerlike hyaline pseudopodia are formed. At the posterior end of(More)
The morphology of the Pelomyxa secunda (Gruber, 1884) comb. nov. pelobiont was studied at light and ultrastructural levels. The locomotive forms are oblong and cigar-shaped. The size range of moving specimens constitutes from 200 to 300 μm. Larger specimens reaching 400 μm are not capable of directed movement. At the sides of the body and at the frontal(More)
The morphology of Mastigamoeba aspera, a typical species of the genus Mastigamoeba Schulze, 1875, was studied at the optical and electron microscopy level. During movement, M. aspera has an oval or pyriformic shape, with the motile flagella being located at the anterior end of mononuclear forms. In the process of movement, the mastigamoeba surface forms(More)
The structure of a new pelomyxa species was investigated with the use of light- and electron-microscope technique. Motile individuals reach 800 microm in length. There is a thin layer of amorphous glycocalix on the cell surface. Many non-motile flagellae are found mainly in the uroidal zone. The axoneme has a non-stable set of microtubules. There are no any(More)
The mitosis in the free-living flagellate Bodo saltans Ps+ with prokaryotic cytobionts in perinuclear space has been studied. The nuclear division in B. saltans Ps+ occurs by closed mitosis type without condensation of chromosomes. Two spatially separated mitotic spindles begin to form consistently at the initial stages of nuclear division. The spindle(More)
Cell organization of a multinuclear pelobiont Pelomyxa prima has been studied at the light and electron microscopic levels. Motile individuals demonstrate a characteristic drop-like or pyriform shape and reach 550 microkm in length. The cell cover is represented by a well-developed, morphologically differentiated glycocalyx 80-100 nm thick. The cytoplasm(More)
The ultrastructure of a marine, free-living heterotrophic kinetoplastid Cruzella marina was investigated with special attention being paid to the mitochondrion and flagellar organization. The flagellates have a polykinetoplastidal mitochondrion. Two flagella emerge from the pocket; one of these turns anteriorly being forward-directed, while the other is(More)
The analysis of ultrastructure organisation and divergent processes in Colpodellida, Perkinsida, Gregarinea and Coccidea has confirmed the presence of unique basic structures in all of these organisms and the necessity to combine them into the single phylum Sporozoa. A taxonomic rank and place of Colpodellida in the system of living organisms is represented(More)
