Q

CAP pathogens?

A
  • Strep pneumo most common (also most frequent cause of bacteremic PNA from community)

  • Klebsiella = alcoholism
  • Pseudomonas = structural lung disease, chronic steroids
  • Staph aureus = think if CAP follows influenza, cavitary PNA, IVDU, recent MRSA skin/soft tissue infection
