Also known as a tachyzoic merozoite (same journal reference as for "bradyzoic merozoite", above). An oocyst (G. ōon, egg + kystis, bladder) is a hardy, thick-walled spore, able to survive for lengthy periods outside a host. The zygote develops within the spore, which acts to protect it during transfer to new hosts.
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 ...
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 ...
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 ...
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.

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. This reproductive stage of the protozoan organism transforms around 25 °C (77 °F), and thrives best at approximately 42 °C (108 °F), multiplying through binary fission .
