Capnocytophaga canimorsus is a Gram-negative, fusiform, rod-shaped organism that is part of the normal oral flora of dogs, cats, and other animals. A significant number of Emergency Department (ED) patients are surgically or functionally asplenic and may be at marked risk for overwhelming post-splenectomy infection (OPSI). OPSI has a mortality rate estimated to be up to 70%. The risk of sepsis is estimated to be 30-60 times greater after splenectomy, and C. canimorsus is one of the organisms that can cause catastrophic OPSI. ⋯ Patients status-post-splenectomy are at greatly increased risk for infection from encapsulated organisms and other organisms, including C. canimorsus, which is part of the normal oral flora of dogs, cats, and other animals. It can be spread to humans by bites, scratches, or less invasive forms of animal-human contact. C. canimorsus infection can lead to OPSI. Early recognition and aggressive clinical management, including early goal-directed therapy and rapid administration of antibiotics, may minimize the morbidity and mortality of this condition and other etiologies of severe sepsis and septic shock.
