Answer: • Clinical: Atypical "walking" pneumonia • Culture: Eaton's agar • Treatment: Macrolides or Fluoroquinolones

Extra: Note: Mycoplasma pneumoniae lacks a cell wall, making it naturally resistant to penicillins and cephalosporins. It is associated with high titers of cold agglutinins (IgM).

Flashcard 8: What are the key associations to remember for cold agglutinin?

Answer: IgM, Mycoplasma, Mononucleosis (EBV)
