Question

In malaria, shivering occurs when

• A. Schizonts enter R.B.C
• B. Sporozoites enter human body
• C. Merozoitos are liberated from R.B.C along with toxin
• D. Signet ring stage is attained

Answer 1

The correct option is C Merozoitos are liberated from R.B.C along with toxin

Each merozoite can infect a red blood cell. Within the RBCs, the merozoite matures either into a uninucleated gametocyte, the sexual stage, infectious for Anopheles mosquitoes. The fever and the shivering are associated with the rupture of erythrocytic-stage schizonts. In severe malaria, parasitized RBCs may obstruct capillaries and postcapillary venules, leading to local hypoxia and the release of toxic cellular products.

So, the correct answer is option C.
