Capnocytophaga canimorsus has been recognized as an opportunistic pathogen 
causing systemic infections in immunocompromised individuals. It is part of the 
normal oral flora of the dog, and can be responsible for localized wound 
infections in humans in consequence of bites. This microorganism causes also 
septicemia, meningitis, endocarditis, ocular infections and rarely brain 
abscess. We describe the case of an immunocompetent 28-year-old male with 
temporal brain abscess from Capnocytophaga canimorsus secondary to dog's bite.
