RESUMO
The authors describe a fatal case of purpura fulminans with symmetrical peripheral gangrene and sepsis caused by Capnocytophaga canimorsus in a 45-year-old, previously healthy woman who was bitten by a dog at an animal shelter where she was employed. Absent in this patient were the usual risk factors, including immunosuppression, alcohol abuse, corticosteroid therapy, and splenectomy. The patient's presentation to the emergency room late in the course of the infection probably effected her death. C canimorsus should be strongly suspected in any case of septicemia following a dog bite. Prompt therapy may influence the potentially fatal course of systemic infection. Employees and/or volunteers who work in animal shelters should be cognizant of the potential risks of a dog or cat bite and follow recommended procedures when such an incident occurs.
