Options

A. Filaria or Wuchereria
B. Ancylostoma
C. Enterobius
D. Ascaris

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for an intestinal parasite that specifically feeds on tissue and blood. This indicates that we are looking for a parasite that has a more invasive feeding mechanism rather than just consuming the contents of the intestine.

2. **Analyzing the Options:**
We have four options to consider:
- **Filaria (or Wuchereria)**
- **Ancylostoma**
- **Enterobius**
- **Ascaris**

3. **Evaluating Each Option:**
- **Filaria (Wuchereria):** This parasite is known to inhabit the lymphatic system and primarily feeds on tissue fluids rather than directly on blood and tissue in the intestinal tract.
- **Ancylostoma:** This is a type of hookworm that attaches to the intestinal wall and feeds on blood and tissue. It is known for causing anemia in hosts due to its blood-feeding behavior.
- **Enterobius:** Commonly known as pinworm, this parasite primarily feeds on the contents of the intestine rather than on blood or tissue.
- **Ascaris:** This is a large roundworm that lives in the intestines and feeds on the luminal content, such as digested food, rather than directly on tissue or blood.

4. **Identifying the Correct Answer:**
After evaluating all the options, **Ancylostoma** is the only parasite that feeds on blood and tissue, making it the correct answer to the question.

5. **Final Answer:**
The intestinal parasite that feeds on tissue and blood is **Ancylostoma**.
