Background and purpose: 

The species of Capnocytophaga and Aggregatibacter are normal flora and mostly cause periodontal diseases. The soft tissue infection caused by Aggregatibacter often is associated with Actinomyces species. Beside, most Capnocytophaga infections are described in immunocompromised patients. We identified facial cellulitis caused by Capnocytophaga spp and Aggregatibacter (Actinobacillus) actinomycetemcomitans in a 16-year-old immunocompetent female.
