Minor criteria include the following:

  • Predisposing heart condition or intravenous drug use

  • Fever of 38°C (100.4°F) or higher

  • Vascular phenomenon, including major arterial emboli, septic pulmonary infarcts, mycotic aneurysm, intracranial hemorrhage, conjunctival hemorrhage, or Janeway lesions

  • Immunological phenomenon such as glomerulonephritis, Osler nodes, Roth spots, and rheumatoid factor

  • Positive blood culture results not meeting major criteria or serologic evidence of active infection with an organism consistent with IE (eg, Brucella, C burnetii [ie, Q fever], Legionella)

  • Echocardiogram results consistent with IE but not meeting major echocardiographic criteria
