Community-Associated MRSA


Community-associated MRSA (CA-MRSA) is MRSA contracted outside of the healthcare setting, usually in healthy individuals. CA-MRSA is associated with many serious infections; however, skin infections are the most common presentation of CA-MRSA. 

Lethal Toxin

CA-MRSA often carries the Panton-Valentine leukocidin  (PVL) gene allowing it to produce a lethal toxin. 

  • The cytotoxin (cell toxin) can destroy both tissue and white blood cells. This categorizes it as a flesh-eating bacteria

MRSA Skin Infections 

Skin infections are the most common presentation of CA-MRSA.

Superficial MRSA Skin Infections include:

  • Pimples, boils and impetigo 

    If left untreated, superficial infections have potential to progress into serious, invasive infections. 

Deep MRSA Skin Infections include:

  • MRSA Cellulitis – a deep skin infection extending into underlying tissue.
  • MRSA Abscess – a deep pocket of pus.
  • Cellulitis and abscesses may be small and localized, or progress into serious/invasive infections
