Type II = predominantly Group A strep

Front 11

Necrotizing fasciitis description

Back 11

o Swollen, shiny, hot, without margins, tender
• Progresses rapidly to gangrene
• Skin becomes anesthetic because of thrombosis
• Crosses fascial planes, compartment syndrome with myonecrosis

Back 12

o Form of necrotizing fasciitis that occurs in the scrotum
o Mixed organisms (gram negs and anaerobes)
• High mortality; requires immediate surgical debridement

CA-MRSA (community associated staph aureus is more likely to

Back 16

• In younger patients
• In non-white patients
• With skin/soft tissue or otitis media
• Broadly susceptible to antibiotics
-Use bactrim and clindamycin
• Much shorter doubling time (grows faster)
