Because of the ability of S aureus to produce an endotheliosis, the presence of a continuous bacteremia does not necessarily imply an infected valvular vegetation.

An important clue to continuous bacteremia/IE is the presence of S aureus bacteriuria associated with hematuria. Hematuria in the setting of IE is due to embolic renal infarction or immunologically mediated glomerulonephritis. Echocardiography has developed into a useful tool for meeting this clinical challenge.
