A case of bacterial empyema caused by Gemella morbillorum

Abstract

A 44-year-old female with diabetic ketoacidosis was admitted due to right back pain and dyspnea. A chest roentgenogram showed accumulation of fluid in the right pleural space. A drain was inserted into the right thoracic cavity and pleural fluid yielded a putrid odor. Gemella morbillorum was diagnosed based on culture of the fluid. She was treated with clinidamycin and panipenem/betamipron intravenously and insertion of a drainage tube. The in vitro activity of CLDM and PAPM/BP against G. morbillorum were less than 0.025 micrograms/ml and 0.05 micrograms/ml, respectively. She was cured and discharged after 28 days of hospitalization, the portal of entry was thought to be connected with dental caries.
