Fatal capnocytophaga infection associated with splenectomy

A case of fatal sepsis due to Capnocytophaga species is described. Capnatophaga canimorsus and C. cynodegmi can cause localized wound infections and/or systemic infections in people who have been bitten, licked, scratched, or merely exposed to cats or dogs, especially splenectomized individuals. A thorough social, medical, and surgical history, the clinical presentation, and cultures are important in making the diagnosis of Capnocytophaga infections. It is important that the forensic pathologist be aware of this zoonotic disease.
