Streptococcus bovis bacteremia is an important early clue to the presence of serious and clinically unexpected gastrointestinal disease, particularly carcinoma of the colon. S. bovis bacteremia has also been associated with carcinoma of the esophagus and stomach, gastric lymphoma, pancreatic adenocarcinoma, intestinal diverticulosis and single adenomatous polyps and villous polyps of the colon. We report a patient with S. bovis endocarditis as the initial clinical manifestation of extensive polyposis of the colon and rectum. All patients with S. bovis bacteremia need thorough investigation of their gastrointestinal tract even in the absence of symptoms, signs, or positive laboratory tests suggestive of gastrointestinal pathology.

Diverticular disease has become a very common condition in elder and more recently in younger patients in western countries that emerged at the turn of the 20th century and since then has become epidemic. An increasing incidence and an earlier onset of the disease lead us to update the current therapeutic indications, especially for surgery in elective condition. Whereas elective colectomy was performed for poorly documented suspicions of diverticulitis in the past, a positive diagnosis of diverticulitis on CT scan is needed. Therefore, indications for colectomy are restricted to patients with medical history of related endocarditis, diabetes mellitus, proven structural abnormalities of collagen, immune deficiency, after a second episode of diverticulitis requiring at least an hospitalisation or after a single complicated diverticulitis (abscess, fistula, stricture). A two-months delay between symptoms and surgery is suitable, and permits to perform preoperatively a colonoscopy in a safe condition to rule out concomitant adenoma or colonic cancer. There is no randomised trial of open versus laparoscopic colectomy in this specific indication. As the lesions of resected colon became more severe due to restricted indications, laparoscopic approach will require more surgical skill and conversion rate might increase. In selected cases, open surgery should be preferred.

Gemella haemolysans, Streptococcus equinus and Tropheryma whipplei are rare Gram-positive bacteria which may cause endocarditis and are associated with gastrointestinal disorders. We report on three patients with infective endocarditis caused by these microorganisms. G. haemolysans and S. equinus (Streptococcus bovis group) were isolated from blood cultures, and T. whipplei was diagnosed by molecular typing of an excised heart valve. The association between endocarditis caused by these microorganisms and gastrointestinal disorders warranted further examination. Endoscopic examination revealed a colonic carcinoma in the patient with G. haemolysans endocarditis and diverticulosis in the patient with S. equinus endocarditis. No gastrointestinal tract disorders were found in the patient with T. whipplei endocarditis, but this does not exclude Whipple's disease. Examination of the gastrointestinal tract for a focus of infection should be considered in patients with endocarditis caused by G. haemolysans, S. equinus and T. whipplei if no other source of bacteraemia is apparent.
