    Abstract:
    We review the syndrome of Capnocytophaga canimorsus (DF-2) septicemia after exposure to dogs or cats. We describe a previously healthy patient who developed diffuse intravascular coagulation and symmetrical peripheral gangrene as a result of C. canimorsus septicemia after a dog bite. To our knowledge, this patient was the first to receive combined plasmapheresis and leukapheresis for C. canimorsus septicemia. Symmetrical peripheral gangrene is frequently associated with C. canimorsus septicemia and may lead to an early diagnosis in patients who become severely ill after a dog bite. Other complications include arthritis, meningitis, and endocarditis. These manifestations can also be found in previously healthy patients, although a prior splenectomy or other causes of impaired host defense clearly enhance the risk. Prompt treatment with penicillin G is required.
