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.
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.
Treatment for CA-MRSA
- Most CA-MRSA skin infections can be treated successfully in the outpatient setting. However, if treatment is delayed, serious or life-threatening infections can occur.
