-Local infections:
-respiratory=pneumonia w/ cavitation
-Systemic Infections: acute endocarditis, meningitis, osteomyelitis, septic arthritis, pyelonephritic
-Toxin mediated: toxic shock syndrome (TSST1), scalded skin syndrome (ritter’s disease), food poisoning
-LESS COMMON: pneumonia+UTI
-1/4 most common cause of nosocomial infections (surgery wounds)
