Stomatococcus mucilaginosus septicemia in two bone marrow transplanted patients

A 44-year-old man with chronic myeloid leukemia and a 10-year-old boy with adrenoleukodystrophy, both admitted for bone marrow transplantation in December 1992, developed clinical signs of septicemia within 2 weeks after transplantation. Three strains of Stomatococcus mucilaginosus were isolated from blood cultures. These were among the first cases of S. mucilaginosus infection diagnosed at our Laboratory and the first reported from Scandinavia. S. mucilaginosus is part of the endogenous oral flora. Both patients had signs of oral mucositis. All 3 strains were isolated earlier with the Laboratory's present blood culture system, compared with the one in use before spring 1992.
