New anaerobic bacteria causing infection: Bacteremia due to Murdochiellaasaccharolytica.

ABSTRACT

Murdochiella asaccharolytica is a Gram-positive anaerobic coccus firstly isolated from wound specimens, since then, it was very rarely isolated from human infections. We report the first case of bloodstream infection due to this bacterium in a 90 years-old-man. The patient had a history of B-cell lymphoma and presented with pain and induration of the base of penis along with fever. A blood culture was obtained yielding M. asaccharolytica in pure culture. Only resistance to clindamycin was demonstrated. Treatment with metronidazole was started and the clinical evolution improved with antimicrobial treatment, being discharged after 6 days.
