Question

Which of the following is a causative organism for Syphilis:

• A. \( \text{Vibrio cholerae} \)
• B. \( \text{Treponema pallidum} \)
• C. \( \text{Bacillus pertussis} \)
• D. \( \text{Clostridium tetani} \)

Hint:

Syphilis progresses through several stages: primary, secondary, latent, and tertiary. Early diagnosis and treatment with antibiotics like penicillin are critical to preventing severe complications.

Answer 1

The Correct Option is B

Step 1: Understanding Syphilis. Syphilis is a sexually transmitted infection (STI) caused by the bacterium \( \text{Treponema pallidum} \). It is a spirochete bacterium that primarily spreads through sexual contact or from mother to fetus during pregnancy (congenital syphilis). 

Step 2: Comparison with other organisms. - Option \( (A) \): \( \text{Vibrio cholerae} \) causes cholera, an acute diarrheal disease. 
- Option \( (C) \): \( \text{Bacillus pertussis} \) causes whooping cough (pertussis). 
- Option \( (D) \): \( \text{Clostridium tetani} \) causes tetanus, characterized by severe muscle spasms. 

Step 3: Conclusion. Only \( \text{Treponema pallidum} \) is the causative organism for syphilis. 

Conclusion: The correct answer is \( (B) \ \text{Treponema pallidum} \).
