BSF has not been reported in the city of Rio de Janeiro in the last three decades, and the present description should alert the clinicians to its presence in urban Rio de Janeiro, and to the differential diagnosis with dengue fever, gastroenteritis, leptospirosis...

Objectives: To describe aspects of S. bovis endocarditis. Methods: This is a case series of patients admitted to a cardiac surgery referral center, during the years 2005-2014. Clinical, laboratory, echochardiographic, colonoscopic, treatment, surgical and outcome variables were studied. Results: Nine patients with S. bovis endocarditis were included; all cases fulfilled the modified Duke criteria. Incidence was 8/220 (4%) in years 2006-2014. There were seven male and two female patients; mean age was 56.7 years, standard deviation 13.4. All patients had native aortic valve involvement....
