Fulminant septicaemia caused by multi-drug-resistant Streptococcus mitis following unrelated cord blood transplantation.

Streptococcus mitis (a common and usually harmless bacterium found in the nose, mouth and throat) can have an unusually high level of resistance to β-lactam antibiotics. We report a patient who developed fatal Streptococcus mitis septicaemia following unrelated cord blood transplantation. Administration of vancomycin to patients with recurrent fever during allogeneic stem cell transplantation might be indicated. [ABSTRACT FROM AUTHOR]
