Give the correct matching of causative agent/germ and disease

Options

A. Anopheles - malaria
B. Leishmania - sleeping sickness
C. Glossina - kala-azar
D. Wuchereria - filariasis

Explanation

To solve the question of matching the causative agent/germ with the disease, we will analyze each option provided in the question:

1. **Anopheles - Malaria**:
- Anopheles is a genus of mosquitoes that act as vectors for the malaria parasite. However, the actual causative agent of malaria is **Plasmodium**. Therefore, this match is **incorrect**.

2. **Leishmania - Sleeping sickness**:
- Sleeping sickness, also known as African trypanosomiasis, is caused by the protozoan parasite **Trypanosoma brucei**, not Leishmania. Leishmania is responsible for leishmaniasis. Hence, this match is also **incorrect**.

3. **Glossina - Kalazar**:
- Kalazar, or visceral leishmaniasis, is caused by the protozoan **Leishmania donovani** and is transmitted by sandflies, not by Glossina (which is the tsetse fly). Therefore, this match is **incorrect**.

4. **Wuchereria - Filaria**:
- Wuchereria bancrofti is a parasitic filarial nematode that causes lymphatic filariasis. This is the correct match as Wuchereria is indeed the causative agent for filariasis.

Thus, the correct matching of causative agent/germ and disease is:
- **Wuchereria - Filaria**.

### Summary of Correct Matches:
- Anopheles - Malaria: Incorrect (Causative agent is Plasmodium)
- Leishmania - Sleeping sickness: Incorrect (Causative agent is Trypanosoma)
- Glossina - Kalazar: Incorrect (Causative agent is Leishmania)
- **Wuchereria - Filaria: Correct**
