A merozoite (G. meros, part [of a series] + zōon, animal) is the result of merogony that takes place within a host cell. During this stage, the parasite infects the host's cells and then replicates its own nucleus and induces cell segmentation in a form of asexual reproduction.
A trophozoite (G. trope, nourishment + zoon, animal) is the activated, feeding stage in the life cycle of certain protozoa such as malaria-causing Plasmodium falciparum and those of the Giardia group. [1] The complementary form of the trophozoite state is the thick-walled cyst form. They are often different from the cyst stage, which is a ...
A trophozoite feeds on the haemoglobin and forms a granular pigment called haemozoin. Unlike those of other Plasmodium species, the gametocytes of P. falciparum are elongated and crescent-shaped, by which they are sometimes identified. A mature gametocyte is 8–12 μm long and 3–6 μm wide. The ookinete is also elongated measuring about 18 ...
Plasmodium is a eukaryote but with unusual features.. The genus Plasmodium consists of all eukaryotes in the phylum Apicomplexa that both undergo the asexual replication process of merogony inside host red blood cells and produce the crystalline pigment hemozoin as a byproduct of digesting host hemoglobin.

Inside the host, the sporulated oocyst opens, and eight sporozoites are released. Each one finds a home in an intestinal cell and starts the process of reproduction. These offspring are called merozoites. When the cell is stuffed full of merozoites, it bursts open, and each merozoite finds its own intestinal cell to continue the cycle. [3]
A woman who underwent a trial immunotherapy as a child for neuroblastoma — an aggressive nerve tissue tumor that occurs often in children under 5 — has since been in remission for 18 years ...
Plus, as Dr. Clark notes, exercise can help you, too. Research shows that physical activity not only improves your overall health and well-being, but it can reduce the risk of morbidity and ...
The trophozoite is conical in shape. Two types of schizogony occur in this family. In the first type the schizonts divide into merozoites with small nuclei. These are known as mycetoids merozoites. These develop into trophozoites.
