Find out the correct match

Options

A. AIDS-Bacillus anthracis
B. Syphilis -Treponema pallidum
C. Gonorrhoea-Leishmania donovanii
D. Urethritis - Entamoeba gingivalis.

Answer

To solve the question of finding the correct match, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Option 1: AIDS - Bacillus anthracis**
- **Analysis**: Bacillus anthracis is a bacterium that causes anthrax, while AIDS (Acquired Immunodeficiency Syndrome) is caused by the Human Immunodeficiency Virus (HIV). Since these two are not related, this option is incorrect.

2. **Option 2: Syphilis - Treponema pallidum**
- **Analysis**: Syphilis is a sexually transmitted disease caused by the bacterium Treponema pallidum, which is a spirochete. This pairing is correct as both the disease and the causative agent are accurately matched.

3. **Option 3: Gonorrhea - Leishmania donovani**
- **Analysis**: Gonorrhea is a sexually transmitted disease caused by the bacterium Neisseria gonorrhoeae. Leishmania donovani, on the other hand, is a protozoan that causes Leishmaniasis. Therefore, this option is incorrectly matched.

4. **Option 4: Urethritis - Entamoeba gingivalis**
- **Analysis**: Urethritis is the inflammation of the urethra, which can be caused by various bacteria or viruses. Entamoeba gingivalis is a protozoan that is not typically associated with urethritis. Thus, this option is also incorrectly matched.

### Conclusion:
The correct match is **Option 2: Syphilis - Treponema pallidum**.
