Eikenella corrodens is a Gram-negative facultative anaerobic bacillus that can cause severe invasive disease in humans.[1] It was first identified by M. Eiken in 1958, who called it Bacteroides corrodens.[2] E. corrodens is a rare pericarditis associated pathogen.[3] It is a fastidious, slow growing, human commensal bacillus, capable of acting as an opportunistic pathogen and causing abscesses in several anatomical sites, including the liver, lung, spleen, and submandibular region.[4] E. corrodens could independently cause serious infection in both immunocompetent and immunocompromised hosts.[5]
