TLDR
A study of merozoite formation in the rodent malaria parasite Plasmodium vinckei, with both light and electron microscopes, has indicated that the cycle in the red cell has 3 successive phases.Abstract:
A study of merozoite formation in the rodent malaria parasite Plasmodium vinckei, with both light and electron microscopes, has indicated that the cycle in the red cell has 3 successive phases: 1. 1. Several nuclear divisions (usually 3), without cytoplasmic cleavage to produce a true “plasmodium” or syncytium with 8 nuclei. 2. 2. The formation of cytoplasmic protrusions by the plasmodium: each nucleus of the plasmodoum then migrates into one of these protrusions. 3. 3. The nucleated protrusions become detached as merozoites leaving a residual body in which pigment granules are segregated.read more

A Brief Illustrated Guide to the Ultrastructure of Plasmodium falciparum Asexual Blood Stages
TL;DR: An illustrated overview of the three-dimensional (3-D) organization of the merozoite, ring, trophozoite and schizont stages of the parasite, based on available data that include 3-D reconstruc-tion from serial electron microscope sections is given.
Journal ArticleDOI
Daughter cell assembly in the protozoan parasite Toxoplasma gondii.
TL;DR: Time-lapse video microscopy permits the entire cell cycle of these parasites to be visualized in vivo, suggesting fundamental similarities between cell division in T. gondii and other apicomplexan parasites.
Journal ArticleDOI
Plasmodium falciparum apical membrane antigen 1 (PfAMA-1) is translocated within micronemes along subpellicular microtubules during merozoite development.

TL;DR: This result confirms that PfAMA-1 is a micronemal protein, and indicates that within the microneme it is located near or inserted into this organelle's boundary membrane.

Pneumocystis carinii Delanoë, its ultrastructure and ultrastructural affinities.
Jiri Vavra,K. Kucera +1 more
TL;DR: It is concluded from the ultrastructural evidence that Pneumocystis may indeed be a yeast or have a yeast-like stage in its life cycle, but it is not completely similar to any fungus whose ultrastructure has been described so far.

TL;DR: Several major shifts of taxonomic significance have been introduced at all levels treated, including the subphyla, and these revisions are explained in appropriately placed footnotes.

The feeding mechanism of avian malarial parasites
TL;DR: Electron microscope studies of the erythrocytic forms, including gametocytes and asexual schizonts, of the protozoa Plasmodium fallax, P. lophurae, and P. cathemerium have revealed a "cytostome," a specialized organelle of the pellicular membrane which is active in the ingestion of host cell cytoplasm.

Phagotrophy and two new structures in the malaria parasite Plasmodium berghei.
TL;DR: Continuity between these bodies and the host cytoplasm was found in a number of electron micrographs, showing that the bodies are formed by invagination of the double plasma membrane of the parasite.
Journal ArticleDOI
Pinocytotic uptake and the digestion of hemoglobin in malaria parasites.
TL;DR: Electron micrographs showed that all these malaria parasites feed on their host cell by pinocytosis, and they contain all the major nuclear and cytoplasmic organelles present in other cells with the exception of mitochondria, which were found only in P. falciparum.
