핵심 개념

• Impetigo — A highly contagious superficial bacterial skin infection commonly caused by Staphylococcus aureus or Streptococcus pyogenes, characterized by honey-colored crusts or bullae.
• Mupirocin — A topical antibiotic effective against gram-positive bacteria, often used as first-line treatment for limited impetigo by inhibiting bacterial protein synthesis.
• Bullous impetigo — A form of impetigo caused by Staphylococcus aureus, presenting with fluid-filled blisters that rupture easily, more common in infants and young children.
• Cellulitis — A deeper skin infection involving subcutaneous tissues, which may complicate untreated or widespread impetigo and typically requires systemic antibiotics.
• Antibiotic resistance — The ability of bacteria to withstand the effects of an antibiotic, emphasizing the importance of appropriate antibiotic selection in impetigo treatment to prevent misuse.
