Streptococcus agalactiae-Related Splenic Abscess in Uncontrolled Diabetes Mellitus.

The spectrum of microorganisms causing splenic abscess is large, and commonly involved organisms include Enterobacteriaceae, gram-positive cocci and anaerobes. Group B Streptococcus (GBS) commonly causes infection in newborns and pregnant women, but there is increasing incidence of GBS causing invasive infection among nonpregnant adults, particularly among diabetics. Common presentations of GBS infection in adults include bacteremia, soft-tissue and skin infection, pneumonia, urinary tract infection, meningitis and endocarditis. We report a case of splenic abscess due to Streptococcus agalactiae infection without endocarditis in a diabetic patient.
