A trophozoite (G. trophē, nourishment + zōon, animal) is the activated, intracellular feeding stage in the apicomplexan life cycle. After gorging itself on its host, the trophozoite undergoes schizogony and develops into a schizont, later releasing merozoites.
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 ...
In the liver it grows into an ovoid schizont of 30–70 μm in diameter. Each schizont produces merozoites, each of which is roughly 1.5 μm in length and 1 μm in diameter. In the erythrocyte the merozoite form a ring-like structure, becoming a trophozoite. A trophozoite feeds on the haemoglobin and forms a granular pigment called haemozoin.
Some cell types: ookinete, sporozoite, merozoite. The phylum Apicomplexa contains all eukaryotes with a group of structures and organelles collectively termed the apical complex. [7] This complex consists of structural components and secretory organelles required for invasion of host cells during the parasitic stages of the Apicomplexan life ...
The trophozoite stage is the infective phase for humans, during which the organism can actively feed and replicate. The trophozoite attaches to the olfactory epithelium, follows the axons of olfactory receptor neurons through the cribriform plate in the nasal cavity, and enters the brain.
Trophozoite and merozoite growth ruptures the host erythrocyte, leading to the release of vermicules, the infectious parasitic bodies, which rapidly spread the protozoa throughout the blood. [9] It is important to pay attention to particular morphologies of Babesia in blood smears, because of its great similarity to the malarial parasite ...

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]
