Streptococcus bovis, a group D non-enterococcal organism has recently received increased attention, especially for its role as a cause of infective endocarditis and associated colorectal neoplasm. Infectious endocarditis due to group D streptococci include two non-enterococcal species, S. bovis and S. equinas, which may be mistaken for enterococci in clinical laboratory. However, S. bovis is readily distinguished from the enterococci by screen with bile-esculin hydrolysis and growth in 6.5% NaCl broth. Although endocarditis caused by S. bovis or enterococci share common clinical findings, therapeutically and prognostically, S. bovis endocarditis more resembles infection with viridans group organism. Also the infection of S. bovis significantly increased the prevalence of colorectal cancer in previous report. As discussed above, the patients with S. bovis endocarditis are carried out study of colorectal cancer. We report a case of endocarditis with colon cancer caused by S. bovis in 54 year old female.
