Which of the following will occur in the vertebrae host with respect to plasmodium ?
(a) Formation of the motile zygote
(b) Maturation of gametocytes (c) Formation of Sporozoites
(d) Release of homozoin
(e) Recurrent fever

Options

A. a,c,d
B. a,b,c,d,e
C. b,d and e
D. d and e only

Answer

To solve the question regarding what occurs in the vertebrate host with respect to Plasmodium, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Plasmodium Lifecycle**:
- Plasmodium is a genus of parasites that cause malaria. Its lifecycle involves two hosts: the female Anopheles mosquito (vector) and the human (vertebrate host).

2. **Analyzing Each Option**:
- **(a) Formation of the motile zygote**:
- This process occurs in the stomach of the mosquito after fertilization of the gametes. Therefore, this does not occur in the vertebrate host. **(Incorrect)**

- **(b) Maturation of gametocytes**:
- Gametocytes develop from the asexual stages of Plasmodium in the human host, specifically within red blood cells (RBCs). This process does occur in the vertebrate host. **(Correct)**

- **(c) Formation of Sporozoites**:
- Sporozoites are formed in the mosquito's gut after the fertilization of gametes and migrate to the salivary glands of the mosquito. This does not occur in the vertebrate host. **(Incorrect)**

- **(d) Release of hemozoin**:
- Hemozoin is a byproduct of the digestion of hemoglobin by the Plasmodium parasite. It is released into the bloodstream when infected red blood cells burst. This process occurs in the vertebrate host. **(Correct)**

- **(e) Recurrent fever**:
- Recurrent fever is a symptom of malaria caused by the cyclical rupture of red blood cells and the release of merozoites and hemozoin into the bloodstream. This occurs in the vertebrate host. **(Correct)**

3. **Conclusion**:
- The correct options that occur in the vertebrate host are (b) Maturation of gametocytes, (d) Release of hemozoin, and (e) Recurrent fever. However, since the question asks for what occurs specifically with respect to Plasmodium in the vertebrate host, the most direct answer is (b) Maturation of gametocytes.

### Final Answer:
The correct answer is **(b) Maturation of gametocytes**.
