A brain abscess caused by Porphyromonas gingivalis / 대한내과학회지

ABSTRACT

Porphyromonas gingivalis is a gram-negative, anaerobic, rod-shaped bacterium originally classified within the Bacteroides genus, and a major etiological agent in the initiation and progression of severe periodontal disease. P. gingivalis has occasionally been involved in otitis media, lung abscesses, gas gangrene, appendicitis, sinusitis, paranasal mucocele, peri-tonsillar abscesses, pleura-pulmonary infections, and thoracic empyema. We report the case of a 44-year-old male who presented with a brain abscess in which the organism, presumably originated from his poor dentition. He was successfully treated with surgical drainage and antibiotics.
