Stomatococcus mucilaginosus: an emerging pathogen in neutropenic patients

Clin Infect Dis. 1992 Mar;14(3):641-6. doi: 10.1093/clinids/14.3.641.


Stomatococcus mucilaginosus was isolated from eight neutropenic patients during nine febrile episodes over a 13-month period. Five of these isolates were from definite infections, including one case of fatal meningitis. This slime-producing, catalase-variable, gram-positive coccus is a component of the normal oral flora of humans. Its biochemical profile may result in misidentification; however, unlike most micrococci, it characteristically fails to grow on media containing 5% NaCl. All but one of our isolates were sensitive to benzylpenicillin, and all were sensitive to vancomycin. S. mucilaginosus may prove to be an important pathogen in severely immunocompromised patients.
