Hepatic abscess due to Dialister pneumosintes - A case report

Abstract

Dialister pneumosintes is an obligate anaerobic Gram-negative rod associated with infections of the oral cavity. We report on a previously healthy, 51-year-old woman who presented with a liver abscess caused by Dialister pneumosintes as a complication of a dental abscess. The microorganism was identified by using a broad-range bacterial 16S rRNA gene PCR in the liver exudate. The patient was cured after abscess drainage and 4-week antibiotic treatment. Our case highlights the importance of a good history and physical examination when taking care of patients admitted for pyogenic liver abscess.
