Rare cases reported in the literature suggest possible extraintestinal dissemination by unclear mechanisms. We followed a 43\u2010year\u2010old Peruvian woman presenting with low\u2010grade fever and gastrointestinal symptoms who was diagnosed with a liver abscess by ultrasound and CT imaging. Identification of the causative agents was achieved through a combination of mass spectrometry, molecular methods (PCR and Sanger sequencing) and culture\u2010based methods in blood, tissue and faecal samples. We detected gut\u2010associated aerobic and anaerobic bacteria, including\n                    <jats:italic>Escherichia coli<\/jats:italic>\n                    ,\n                    <jats:italic>Eikenella corrodens<\/jats:italic>\n                    and\n                    <jats:italic>Bacteroides fragilis<\/jats:italic>\n                    .
