Question

A male patient came to OPD with white discharge from urethra [Image Shown]. What is the most probable organism involved?

• A. Nisseria gonorrhoeae
• B. Haemophilus ducreyi
• C. Calymmatobacterium granulomatis
• D. Treponema pallidum

Hint:

Think about the most common sexually transmitted organism causing purulent urethral discharge in males.

Answer 1

The Correct Option is A

Clinical picture: Male with white urethral discharge -- this is urethritis, most commonly a sexually transmitted infection.

Most probable organism: Neisseria gonorrhoeae (gonococcus) is the classic cause of urethritis with profuse purulent discharge in males. It is a gram-negative diplococcus and causes gonococcal infection (gonorrhea).

Key facts:
- Males: symptomatic (discharge + dysuria)
- Females: often asymptomatic, may present as endocervicitis
- Incubation period: 2-5 days

Why not the others?
- H. ducreyi: painful genital ulcer (chancroid), not discharge
- C. granulomatis: painless beefy-red ulcer (granuloma inguinale)
- T. pallidum: painless indurated chancre (primary syphilis)

\[\boxed{\text{Neisseria gonorrhoeae}}\]
