Staphylococcus aureus is a leading cause of both community-acquired and healthcare-acquired bacteremia. Several important underlying conditions predispose patients to the development of S. aureus bacteremia (SAB). The morbidity and mortality of SAB is high even when appropriate therapy is given.
There are some common illnesses caused by Staphylococcus aureus:
Skin and Soft Tissue Infections
- Folliculitis
- Furuncle, carbuncle
- Cellulitis
- Impetigo
- Mastitis
- Surgical wound infections
- Hidradenitis suppurativa
Musculoskeletal Infections
- Septic arthritis
- Osteomyelitis
- Pyomyositis
- Psoas abscess
Respiratory Tract Infections
- Ventilator-associated or nosocomial pneumonia
- Septic pulmonary emboli
- Postviral pneumonia (e.g., influenza)
- Empyema
Bacteremia and Its Complications
- Sepsis, septic shock
- Metastatic foci of infection (kidney, joints, bone, lung)
- Infective endocarditis
Infective Endocarditis
- Injection drug use–associated
- Native-valve
- Prosthetic-valve
- Nosocomial
Device-Related Infections (e.g., intravascular catheters, prosthetic joints)
Toxin-Mediated Illnesses
- Toxic shock syndrome
- Food poisoning
- Staphylococcal scalded-skin syndrome
Invasive Infections Associated with Community-Acquired MRSA
- Necrotizing fasciitis
- Waterhouse-Friderichsen syndrome
- Necrotizing pneumonia
- Purpura fulminans
