Streptococcus bovis bacteremia: unusual complications.

Streptococcus bovis bacteremia is known to be related to neoplastic lesions of the colon. We describe a patient with several complications of S bovis bacteremia and adenocarcinoma of the colon--endocarditis, spondylodiskitis, and splenic abscess. We believe this is the eighth known case of endocarditis and diskitis caused by S bovis and the third case of endocarditis and splenic abscess by S bovis in a patient with adenocarcinoma of the colon.
