"Capnocytophaga canimorsus" is a Gram-negative bacillus (rod-shaped) bacterium that causes a zoonotic disease, most commonly in asplenic patients. It is a member of the normal gingival flora of dogs and cats. It causes fulminant sepsis with disseminated intravascular coagulation (DIC).

Treatment

Treatment is via antibiotics with the possible aid of activated protein C or plasmapheresis in severe cases.

Following animal bites, co-amoxiclav is often given to asplenic individuals to prevent disseminated infection; but in patients who are allergic to penicillins, the combination of doxycycline and metronidazole (to cover anaerobic organisms) may be used instead.

In patients with sepsis, treatment with imipenem, clindamycin, or a penicillin-β-lactamase inhibitor combination (e.g., co-amoxiclav or piperacillin-tazobactam) should be used.

"Capnocytophaga canimorsus" was previously known as "dysgonic fermenter type 2" (DF2).
