Recurrent high fever in malaria is due to completion of

Options

A. Erythroctic schizony
B. Sporogony
C. Gamogony
D. Exoerythrocytic schizogony

Answer

**Step-by-Step Text Solution:**

1. **Understanding Malaria and Its Causative Agent**: Malaria is caused by the parasite Plasmodium, which has a complex life cycle involving two hosts: the female Anopheles mosquito and humans.

2. **Life Cycle of Plasmodium**: The life cycle of Plasmodium is divided into two main phases:
- **Sexual Cycle**: This occurs in the female Anopheles mosquito.
- **Asexual Cycle**: This occurs in humans, specifically in the red blood cells (RBCs).

3. **Infection Process**: When an infected female Anopheles mosquito bites a healthy human, it injects sporozoites into the bloodstream. These sporozoites travel to the liver, marking the beginning of the exoerythrocytic cycle, which occurs outside the RBCs.

4. **Erythrocytic Cycle**: After the exoerythrocytic phase, the sporozoites develop into merozoites and invade the RBCs. This phase is known as erythrocytic schizogony.

5. **Symptoms of Malaria**: The clinical symptoms of malaria, including recurrent high fever, arise after the completion of the erythrocytic schizogony. This is when the merozoites multiply within the RBCs and eventually lead to their rupture, causing fever and other symptoms.

6. **Conclusion**: Therefore, the recurrent high fever in malaria is due to the completion of erythrocytic schizogony.

**Final Answer**: The correct option is **A. Erythrocytic schizogony**.
