Human inferction of taenia solium through food contaminated with

Options

A. Cystecerci
B. Onchospheres
C. Hexacanths
D. Adult worm

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks how humans can become infected with *Taenia solium*, commonly known as the pork tapeworm, through food contamination.

2. **Identifying the Options**: The provided options are:
- Cysticerci
- Onchosperes
- Hexacans
- Adult worm

3. **Analyzing Each Option**:
- **Cysticerci**: These are the larval stage of *Taenia solium* that can develop in the muscles of pigs. However, humans do not get infected directly through cysticerci.
- **Onchosperes**: This term seems to refer to oncospheres, which are the embryonated eggs of *Taenia solium*. These eggs can contaminate food and are ingested by pigs, leading to the formation of cysticerci in their muscles.
- **Hexacans**: This term does not relate to *Taenia solium* infection in humans.
- **Adult worm**: The adult form of *Taenia solium* resides in the intestines of humans but is not what contaminates food.

4. **Correct Answer**: The correct answer is **Onchosperes** (embryonated eggs), as humans can become infected by consuming food contaminated with these eggs, which are often found in human feces.

5. **Conclusion**: Therefore, the human infection of *Taenia solium* is through food contaminated with **onchosperes**.
