The sporozoites that cause infection, when a female Anopheles mosquito bites a person, are formed in

Options

A. liver of human
B. RBCs of mosquito
C. salivary glands of mosquito
D. intestine of mosquito

Answer

To solve the question regarding where sporozoites that cause infection are formed when a female Anopheles mosquito bites a person, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Life Cycle of the Malaria Parasite**:
- The malaria parasite, specifically Plasmodium, has a complex life cycle that involves both humans and mosquitoes.

2. **Infection Process**:
- When a female Anopheles mosquito bites an infected person, it ingests the blood containing the malaria gametocytes (the sexual form of the parasite).

3. **Sporozoite Formation**:
- Inside the mosquito's body, specifically in its **intestine**, the gametocytes develop into sporozoites. This is the stage of the parasite that is capable of causing infection.

4. **Storage of Sporozoites**:
- After their formation in the intestine, the sporozoites migrate to the **salivary glands** of the mosquito. This is where they are stored until the mosquito bites another person.

5. **Conclusion**:
- Therefore, the correct answer to the question is that sporozoites are formed in the **intestine of the mosquito**.

### Final Answer:
The sporozoites that cause infection when a female Anopheles mosquito bites a person are formed in the **intestine of the mosquito**.
