Question

Which of the following is the causative agent for acne fulminans?

• A. Actinomyces
• B. Propionibacterium
• C. Mobiluncus
• D. Bifidobacterium

Hint:

Acne fulminans is a rare, severe form of acne that requires prompt treatment with antibiotics and sometimes steroids to control inflammation and prevent scarring.

Answer 1

The Correct Option is B

Actinomyces: This is a genus of bacteria that is typically associated with actinomycosis, a chronic granulomatous infection that can affect the face, neck, chest, and abdomen. It is not related to acne fulminans.
Propionibacterium: This is the correct answer. Propionibacterium acnes, now called Cutibacterium acnes, is the primary causative agent of acne vulgaris and is also implicated in acne fulminans, a severe and often sudden onset of inflammatory acne. This condition is more common in young males and is characterized by the development of severe, painful, and ulcerative lesions.
Mobiluncus: This genus is typically associated with bacterial vaginosis, not acne fulminans.
Bifidobacterium: This genus is associated with the microbiota of the gut and has no known connection with acne fulminans. Thus, the correct answer is Propionibacterium (2), as it is the primary causative agent for acne fulminans.
