Examination findings that may indicate a specific etiology for consideration are as follows:

  • Bradycardia may indicate a Legionella etiology.

  • Periodontal disease may suggest an anaerobic and/or polymicrobial infection.

  • Bullous myringitis may very rarely indicate Mycoplasma pneumoniae infection (largely disproven).

  • Physical evidence of risk for aspiration may include a decreased gag reflex.

  • Cutaneous nodules, especially in the setting of central nervous system (CNS) findings may suggestion Nocardia infection.
