Asexual cycle of Plasmodium in man comprises of phases [In order]:
Correct answer: E. Pre-erythrocytic phase ⟶ Erythrocytic phase ⟶ Post-erythrocytic phase ⟶ Gamogony
- A. Erythrocytic phase ⟶ Pre-erythrocytic phase ⟶ Gamogony ⟶ Post-erythrocytic phase
- B. Erythrocytic phase ⟶ Gamogony ⟶ Pre-erythrocytic phase ⟶ Post-erythrocytic phase
- C. Pre-erythrocytic phase ⟶ Post-erythrocytic phase ⟶ Gamogony ⟶ Erythrocytic phase
- D. Post-erythrocytic phase ⟶ Pre-erythrocytic phase ⟶ Erythrocytic phase ⟶ Gamogony
- E. Pre-erythrocytic phase ⟶ Erythrocytic phase ⟶ Post-erythrocytic phase ⟶ Gamogony
Explanation
The Plasmodium life cycle in humans starts with the pre-erythrocytic phase, where sporozoites infect liver cells and multiply. It is followed by the erythrocytic phase, characterized by the infection and destruction of red blood cells, causing malaria symptoms. The post-erythrocytic phase entails further development in the blood. Finally, gamogony occurs, where gametocytes form, ready for transmission to a mosquito. Options A, B, C, and D present incorrect sequences that do not correspond to the actual life cycle of Plasmodium in humans.
