Eikenella corrodens isolated from a polymicrobial hepatic abscess.

A 71-yr-old woman developed a hepatic abscess from which Eikenella corrodens was isolated as part of a polymicrobial flora. This facultatively anaerobic organism is now recognized as a true pathogen. Selective culture media may be required to isolate Eikenella corrodens, and it may be resistant to antibiotics commonly used for anaerobic infections. Special attempts to isolate this organism may be indicated when hepatic abscesses are likely to have resulted from spread of oral or abdominal infections.
