Where will you look for the sporozoites of malarial parasite ?

Options

A. Spleen of infected human
B. Saliva of infected female Anopheles
C. Salivary glands of freshly moulted female Anopheles
D. RBCs of persons suffering from malaria.

Answer

To answer the question "Where will you look for the sporozoites of the malarial parasite?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking specifically about the location of sporozoites, which are a stage in the life cycle of the malaria-causing parasite, Plasmodium.

2. **Identify the Life Cycle of the Malaria Parasite**: The malaria parasite has a complex life cycle that involves both the female Anopheles mosquito and humans. The sporozoites are the infective form of the parasite.

3. **Know the Source of Sporozoites**: Sporozoites are produced in the salivary glands of the female Anopheles mosquito. When the mosquito bites a human, it injects saliva containing these sporozoites into the bloodstream.

4. **Evaluate the Options**:
- **Option 1**: Spleen of infected humans - This is incorrect as the spleen is where red blood cells (RBCs) are processed, not where sporozoites are found.
- **Option 2**: Saliva of infected female Anopheles - This is correct because sporozoites are present in the saliva of the mosquito.
- **Option 3**: Salivary gland of freshly malted female Anopheles - This is incorrect as the term "freshly malted" is not relevant here; sporozoites are formed in the salivary glands but are not found there after transmission.
- **Option 4**: RBC of a person suffering from malaria - This is incorrect because RBCs contain merozoites, not sporozoites.

5. **Conclusion**: Based on the evaluation of the options, the correct answer is **Option 2: Saliva of infected female Anopheles**.

### Final Answer:
You will look for the sporozoites of the malarial parasite in the **saliva of infected female Anopheles**.
