Answer

To determine which of the diseases listed is a bacterial disease, we will analyze each option one by one:

1. **Chicken Gunia**:

2. **Rabies**:
- Rabies is caused by the rabies virus, which is typically transmitted through the bite of an infected animal, such as a dog. Since it is caused by a virus, it is also not a bacterial disease.

3. **Encephalitis**:
- Encephalitis is primarily caused by viral infections, with the herpes simplex virus being one of the common causes. Thus, encephalitis is not a bacterial disease.

4. **Plague**:
