Answer

### Step-by-Step Solution:

1. **Identify the Parasite**: The question refers to Ancylostoma, which is a type of hookworm.

2. **Understand the Disease**: Ancylostoma causes a disease known as ankylostomiasis. This disease is primarily associated with the parasitic infection caused by the larvae of Ancylostoma.

3. **Mode of Entry**: The larvae of Ancylostoma can enter the human body through the skin. This typically occurs when individuals walk barefoot on contaminated soil or when they accidentally ingest soil that contains the larvae.

4. **Symptoms of Infection**: Once the larvae penetrate the skin, they can cause several symptoms:
- **Itching and Inflammation**: The larvae wander through the skin, leading to itchy rashes and inflammation.
- **Pulmonary Symptoms**: As the larvae migrate through the body, they can reach the lungs, causing pulmonary infections.
- **Gastrointestinal Symptoms**: After migrating to the small intestine, they can cause diarrhea, abdominal pain, and sometimes bloody stools.

5. **Conclusion**: Therefore, Ancylostoma can cause itching, inflammation of the skin, and pulmonary infections, making the correct answer "all of these."

### Final Answer:
Ancylostoma causes itching, inflammation of the skin, pulmonary infection, and gastrointestinal symptoms, thus the correct answer is "all of these."
