The sporozoites that cause infection when a female Anopheles mosquito bites a human being are formed in

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where the sporozoites, which cause malaria when a female Anopheles mosquito bites a human, are formed.

2. **Identifying the Organism**: The sporozoites are associated with the malarial parasite known as Plasmodium, specifically Plasmodium vivax.

3. **Role of the Female Anopheles Mosquito**: The female Anopheles mosquito is a vector for the Plasmodium parasite. It carries out part of the parasite's life cycle within its body.

4. **Life Cycle of Plasmodium**: The life cycle of Plasmodium involves two hosts: the mosquito and the human. In the mosquito, the parasite undergoes development, and in the human, it causes infection.

5. **Location of Sporozoite Formation**: In the mosquito, the sporozoites are formed in the salivary glands after the parasite has completed its development in the mosquito's body.

6. **Infection Process**: When the female Anopheles mosquito bites a human, it injects saliva containing the sporozoites into the human bloodstream.

7. **Final Answer**: Therefore, the sporozoites that cause infection when a female Anopheles mosquito bites a human being are formed in the **salivary glands of the mosquito**.

**Answer**: Salivary glands of mosquito.
