Bite infections caused by Capnocytophaga canimorsus are rare. Severe and fatal 
infections are more frequently reported in patients with immunodeficiency, 
splenectomy or alcohol abuse. We describe the case of a 63-year-old man who 
developed flu-like symptoms and presented after some delay with severe sepsis 
and purpura fulminans. He was found to be infected with C. canimorsus without a 
bite injury and did not demonstrate immunodeficiency or any other typical 
predisposition. Despite extensive intensive care, his conditions deteriorated 
and he died from multiorgan failure.
LEARNING POINTS: Pet owners with banal, for instance flu-like, symptoms should 
urgently seek medical advice when symptoms are unusual.Capnocytophaga canimorsus 
infection should be considered and empirical antibiotic therapy immediately 
started or adjusted in the presence of purpura fulminans in the absence of 
animal bites or immunodeficiency.
