Empyema caused by eikenella corrodens.

Eikenella corrodens is a fastidious, facultative anerobic, non-motile, gram-negative bacilli that is part of the normal flora of the mouth and upper respiratory tract. It is being increasingly recognized as a human pathogen and has been implicated in a variety of human infections, including, periodontitis, brain abscess, endocarditis, osteomyelitis, intra-abdominal infections, and pleuropulmonary infections. We report, for the first time, from the Himalayan Kingdom of Nepal, a case of left-sided empyema due to Eikenella corrodens, in an 83-year-old man. Eikenella corrodens was isolated as a pure growth from the pleural aspirate, proving its pathogenic potential. Surgical drainage and an appropriate antimicrobial therapy resulted in a therapeutic response. We have discussed the difficulties that can be encountered in isolating Eikenella corrodens and in choosing appropriate antibiotics for its treatment.
