## Abstract

We report a case of Moraxella osloensis bacteremia in a 66-year-old male presenting with acute abdominal pain and intermittent low-grade fevers following a dental extraction. The patient was diagnosed on return to the emergency department after cultures drawn during an initial visit produced a positive result for the organism on polymerase chain reaction (PCR). He was discharged without complication following admission to the hospital for intravenous antibiotics. Clinically significant M. osloensis infection is rare, and we have not found other reports describing a similar presentation with this organism.
