Group G streptococcal endocarditis.
The group G streptococcus may be a more common human pathogen than previously recognized. A case of group G streptococcal endocarditis is reported and the 11 cases reported previously are reviewed. Group G endocarditis may have significant clinical and prognostic differences from endocarditis caused by the more commonly identified viridans or group D streptococci. Routine serologic grouping of beta-hemolytic streptococcal isolates from serious infections is warranted.
