Group G streptococcus has been increasingly reported as a cause of bacteremia and infective endocarditis. The association between various groups of streptococcus with malignancy has been well established. Such association is particularly observed in group D Streptococcus bovis which is commonly reported in association with carcinoma of the colon. We herein report a case of a 72-year-old male who presented with severe sepsis, iron deficiency anemia and newly diagnosed cardiac murmur. Further workup confirmed group G streptococcus bacteremia, infective endocarditis and newly diagnosed carcinoma of the colon. This case highlights a unique association between invasive form of group G streptococcus and colon cancer.
