What bacteria is involved in erysipelas?
Show answer and explanation
Correct answer: B. Streptococcus (beta-hemolytic)
Erysipelas is a superficial skin/soft-tissue infection caused classically by group A beta-hemolytic Streptococcus (Streptococcus pyogenes), producing a sharply demarcated, raised, erythematous plaque. Staphylococcus is more associated with cellulitis with less sharply defined borders, or with impetigo (bullous type).
