Streptococcus bovis endocarditis as a presenting manifestation of idiopathic ulcerative colitis.

Streptococcus bovis bacteraemia and endocarditis have been associated with several gastrointestinal diseases, mainly malignant or potentially malignant tumours, and less commonly non-malignant gastrointestinal disorders. We describe a 73 year old man in whom Streptococcus bovis endocarditis developed, and was the presenting manifestation of undiagnosed quiescent ulcerative colitis. Such an association has not been described previously.
