Abstract
The clinical and bacteriological features of septicemia caused by group G streptococci were analyzed in nine patients seen during a period of 28 months. Four of these patients had acute endocarditis with a high rate of serious neurological complications. The clinical response to antibiotic treatment was slow in the endocarditis patients despite sensitivity of the organism in vitro. Group G streptococcal septicemia can be a very serious condition associated with endocarditis of a destructive nature. Comparison with previous reports suggests that group G streptococcal infections are of increasing importance. The virulence of group G streptococci may be changing, resulting in more serious infections and complications. This series stresses the importance of prompt recognition of this infection and the need for aggressive management of these patients.
