Question

Sporozoites of malarial parasite enter
A. Erythrocytes of humans
B. Liver cells of humans
С. Stomach of Mosquito
D. Salivary gland of Mosquito

Answer 1

The sporozoites are cells that develop in the mosquito's salivary glands, leave the mosquito during a blood meal, and enter liver cells ( hepatocytes ), where they multiply. Cells infected with sporozoites eventually burst, releasing merozoites into the bloodstream.

Complete answer:
Let’s discuss the question and find the correct answer.

- People have erythrocytes in their blood. The complete surface zone on erythrocytes is corresponding to multiple times the body's absolute outside surface, representing the effectiveness of hemoglobin at conveying oxygen.

- Within 30 minutes or so after immunization into human blood, all sPorozoites vanish from the blood and infiltrate the parenchyma cells of liver by the lytic activity of their secretary organelles.Within half an hour or so after inoculation into human blood, all sporozoites disappear from the blood and penetrate the parenchyma cells of liver by the lytic action of their secretory organelles.

-The malaria parasite life cycle involves two hosts. During a blood meal, an intestinal sickness contaminated female Anopheles mosquito vaccinates sporozoites into the human host. Sporozoites taint liver cells and develop into schizonts, which burst and deliver merozoites.

-The malaria parasite sporozoite sequentially invades mosquito salivary glands and mammalian hepatocytes; and is the Plasmodium life cycle infective form mediating parasite transmission by the mosquito vector.

So (b) is the correct option.

Note: Malaria is transmitted normally via the bite of an infected mosquito. These mosquitoes, consistently female and of the sort Anopheles, convey intestinal sickness parasites in their salivary organs. The parasites, at this aspect of their life cycle known as sporozoites, are brought into the host's blood when the mosquito takes a blood meal.
