摘要：
We report a case of bloodstream infection with the anaerobic bacterium Ruminococcus gnavus (R. gnavus), associated with intestinal perforation in a patient undergoing chemotherapy for multiple myeloma and cancer of the sigmoid colon. Gram staining of positive anaerobic blood cultures revealed both diplococci and short chains of gram-positive cocci. MALDI-TOF MS done directly on the blood culture bottle identified the bacterium as R. gnavus, and 16S rRNA gene sequencing confirmed the identification. (C) 2018 Elsevier Ltd. All rights reserved.
