Abstract
We report a rare case of polymicrobial anaerobic bacteremia caused by four different gut anaerobes: Bacteroides fragilis, Eggerthella lenta, Bilophila wadsworthia, and Ruminococcus gnavus. Early initiation of appropriate therapy and species identification with matrix assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF MS) resulted in full recovery from the infection. Our case highlights the clinical significance of polymicrobial cultures and the importance of performing anaerobic cultures for blood specimens to ensure proper identification and treatment.
