Eikenella corrodens is an anaerobic gram-negative rod that usually does not cause infections of the skin and the soft tissue. It should be suspected as being the causative organism when such infections are not responding to typical antibiotic coverage in a patient's wounds, and there is an antecedent history to suggest that the wound may have been contaminated by saliva. Penicillin G and ampicillin are the drugs of choice for treating infections caused by E. corrodens. It is highly resistant to clindamycin and metronidazole.
