Infective endocarditis caused by Streptococcus bovis is known to be associated with colorectal malignancy.

We present a case of disseminated colorectal carcinoma occurring after a confirmed S sanguis endocarditis, that required mitral valve surgery. There may be a need for gastrointestinal surveillance in patients presenting with bacteraemia caused by less common streptococci.
