Which is showing accurate pairing

Options

A. Syphilis- Treponema pallidum
B. AIDS - Bacillus anthracis
C. Gonorrhoea- Leishmania donovani
D. Typhoid - Mycobacterium leprae

Answer

To determine which pairing of diseases and their causative agents is accurate, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the first disease and its causative agent:**
- **Disease:** Syphilis
- **Causative Agent:** Treponema pallidum
- **Analysis:** Syphilis is indeed a sexually transmitted disease (STD) caused by the bacterium Treponema pallidum.
- **Conclusion:** This pairing is accurate.

2. **Identify the second disease and its causative agent:**
- **Disease:** AIDS
- **Causative Agent:** HIV (Human Immunodeficiency Virus)
- **Analysis:** AIDS is also an STD and is caused by the HIV virus.
- **Conclusion:** This pairing is accurate.

3. **Identify the third disease and its causative agent:**
- **Disease:** Gonorrhea
- **Causative Agent:** Leishmania donovani (incorrect)
- **Analysis:** Gonorrhea is an STD, but it is caused by the bacterium Neisseria gonorrhoeae, not Leishmania donovani, which is associated with a different disease (leishmaniasis).
- **Conclusion:** This pairing is inaccurate.

4. **Identify the fourth disease and its causative agent:**
- **Disease:** Typhoid
- **Causative Agent:** Salmonella typhi
- **Analysis:** Typhoid is not an STD; it is a water-borne disease caused by the bacterium Salmonella typhi.
- **Conclusion:** This pairing is inaccurate.

### Final Conclusion:
The accurate pairings are:
- **Syphilis - Treponema pallidum**
- **AIDS - HIV**
