Abstract:
Phocaeicola (Bacteroides) dorei is a Gram-negative anaerobic bacillus that is rarely isolated from human specimens. Its accurate identification can be hampered by its close taxonomic relationship with Bacteroides vulgatus. We report on two patients with bacteremia due to P. (B.) dorei, which was initially identified as B. vulgatus by MALDI-TOF MS.
