Question

differentiation between the Sporozoites and merozoites.

Answer 1

A merozoite is a daughter cell of a protozoan parasite. Merozoites are the result of asexual reproduction (schizogony, merogony). In coccidiosis, merozoites form the first phase of the internal life cycle of coccidian.

In malaria, these spores infect red blood cells and then rapidly reproduce asexually. These merozoites then can break and destroy the red blood cell hosts and infect others. Antimalarial drugs can cure these infections.

A trophozoite is the activated, feeding stage in the life cycle of protozoan parasites such as the malaria-causing Plasmodium falciparum (the opposite of the trophozoite state is the thick-walled cyst form).

The trophozoite develops into a schizont which is a mother cell which asexually produces daughter cells known as merozoites. Another type of Balantidium coli is cysts.

In the life-cycle of apicomplexan protozoa, sporozoites are cells that infect new hosts. In the parasites that cause malaria (Plasmodium), for instance, the sporozoites are cells that develop in the mosquito's salivary glands, leave the mosquito during a blood meal, and enter the liver where they multiply. Cells infected with sporozoites eventually burst, releasing merozoites into the bloodstream.

Sporozoites are formed by sporogony, a type of sexual or asexual reproduction by multiple fission of a spore or zygote, characteristic of many sporozoans.
