Abstract

Bacteoides finegoldii is a Gram-negative, rod-shaped and obligate anaerobic bacteria isolated in human feces during studies of intestinal microbiota. We present a case report in which B. finegoldii was isolated and identified from the blood culture of a 93-year-old patient with abdominal pain. Microbiological identification was performed by MALDI-TOF MS and confirmed later by 16S rRNA sequencing. An abdomino-pelvic CT scan was conducted, showing a mass of neoplastic appearance that infiltrated the sigmoid colon and bladder, probably producing a colo-vesical fistula. Up to now, this is the first report of B. finegoldii causing human infection.
