Question

A person suffering from a disease caused by Plasmodium, experiences recurring chill and fever at the time when?

• A. The trophozoites reach maximum growth and give out certain toxins
• B. The microgametocytes and megagametocytes are being destroyed by the WBCs
• C. The parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs
• D. The sporozoites released from RBCs are being rapidly killed and broken down inside spleen

Answer 1

The correct option is C

The parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs

The correct option is C.

Explanation of correct option:

1. Plasmodium is a parasitic protozoan that causes malaria in humans.
2. Plasmodium enters our body in the form of sporozoites.
3. After entering the human body, the sporozoites reach the liver cells and grow into schizonts. Later, merozoites are released by the rupture of sporozoites.
4. Merozoites attack RBCs and multiply rapidly inside them. This process eventually ruptures RBCs and releases a toxin called ‘hemozoin’ that causes recurring chill and fever.

Final answer: A person suffering from a disease caused by Plasmodium, experiences recurring chill and fever at the time when the parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs.
