Abstract

We report a case of a 76-year-old Caucasian male with bacteremia caused by Porphyromonas gingivalis and splenic abscess caused by Parvimonas micra. This patient presented with nonspecific symptoms: fever, chills, body aches, and shortness of breath. He was treated with IV piperacillin-tazobactam that was later switched to ampicillin sodium/sulbactam sodium during his hospital course and underwent a splenectomy. He ultimately expired due to acute respiratory failure and cardiac arrest, secondary to post-surgical complications. To our knowledge, this is the first case of P. micra and P. gingivalis coinfection.

Keywords: bacteremia; bacterial co-infection; parvimonas micra; porphyromona gingivalis; splenic abscess.
