Question

A male presented with urethral discharge as shown in figure. What can be the cause?

• A. Gonorrhea
• B. Hemophilus Ducreii
• C. Syphilis
• D. HIV

Hint:

Think of the most common bacterial STI causing profuse purulent urethral discharge in males.

Answer 1

The Correct Option is A

Approach: A male with purulent urethral discharge -- identify the STI.

Key facts about each option:

• Gonorrhea (Neisseria gonorrhoeae): Gram-negative diplococci; causes profuse purulent urethral discharge; incubation 1-14 days; diagnosed by Gram stain showing intracellular diplococci or culture on Thayer-Martin medium.
• Hemophilus Ducreii: Causes chancroid -- soft, painful genital ulcers with suppurative inguinal lymphadenopathy (bubo), not primarily urethral discharge.
• Syphilis (Treponema pallidum): Primary syphilis = painless indurated chancre; does not cause purulent discharge.
• HIV: A retrovirus causing immunosuppression; does not directly cause urethral discharge.

The image shows classic purulent urethral discharge consistent with gonorrhea.
