Charcot-Leyden particles are found in faeces of man during infection of

Options

A. E. histolytica
B. Ascaris
C. T. gambiens
D. Entamoeba coli

Answer

**Step-by-Step Solution:**

1. **Understanding Charcot-Leyden Particles**:
- Charcot-Leyden particles are microscopic crystals that are typically found in human feces. They are derived from the breakdown of eosinophils, which are a type of white blood cell involved in the body's immune response.

2. **Identifying the Source of Infection**:
- These particles are often associated with parasitic infections. One of the key infections that lead to the presence of these particles in feces is caused by the protozoan parasite Entamoeba histolytica.

3. **Mechanism of Infection**:
- When Entamoeba histolytica infects the human body, it forms cysts that can lead to intestinal issues. The presence of this parasite triggers an immune response, resulting in an increase in eosinophils, which eventually break down and contribute to the formation of Charcot-Leyden particles.

4. **Conclusion**:
- Therefore, the presence of Charcot-Leyden particles in the feces of humans is indicative of an infection by Entamoeba histolytica.

**Final Answer**: Charcot-Leyden particles are found in the feces of man during infection of **Entamoeba histolytica**.
