Abstract

We report a case of Bacteroides zoogleoformans liver abscess and bloodstream infection in a 78-year-old man with hepatocellular carcinoma. The microbe was identified by 16S rRNA gene sequencing after matrix-assisted laser desorption/ionization time-of-flight mass spectrometry failed to identify the pathogen. To our knowledge, this case from Japan represents the first report of invasive B. zoogleoformans infection.
