C. Typhoid - Salmonella
D. Kala azar - Leishmania

Answer

To find the mismatch in the given options, we will analyze each disease and its corresponding causative agent step by step.

### Step-by-Step Solution:

1. **Identify the Diseases and Causative Agents**:
- We have the following pairs:
- Sleeping sickness - Trypanosoma
- Syphilis - Trichuris
- Typhoid - Salmonella
- Kala-azar - Leishmania

2. **Analyze Each Pair**:
- **Sleeping Sickness**:
- Causative Agent: Trypanosoma (specifically Trypanosoma brucei)
- This match is correct.

- **Syphilis**:
- Causative Agent: Trypanoma pallidum (not Trichuris)
- This match is incorrect. Here, Syphilis is not caused by Trichuris but by Trypanoma pallidum.

- **Typhoid**:
- Causative Agent: Salmonella (specifically Salmonella typhi)
- This match is correct.

- **Kala-azar**:
- Causative Agent: Leishmania
- This match is correct.

3. **Identify the Mismatch**:
- From the analysis, the only incorrect pair is **Syphilis and Trichuris**. Syphilis is caused by Trypanoma pallidum, not Trichuris.

4. **Conclusion**:
- The mismatch is **Syphilis - Trichuris**. The correct causative agent for Syphilis is Trypanoma pallidum.

### Final Answer:
The mismatch is **Syphilis - Trichuris**.
