Abstract

The prevalence of Capnocytophaga canimorsus and C. cynodegmi in the oral cavities of 120 dogs and 80 cats was investigated using species-specific PCR and culture methods between 2011 and 2012. The PCR detected the C. canimorsus gene in 62% of the dogs and 49% of the cats, whereas the C. cynodegmi gene was detected in 82% of the dogs and 86% of the cats. C. canimorsus was isolated from 4% of the dogs and 4% of the cats, whereas C. cynodegmi was isolated from 38% of the dogs and 41% of the cats. Capnocytophaga spp. from oral swab samples was correctly identified using both the species-specific PCR and culture methods; however, C. cynodegmi was not detected by only the species-specific PCR in some samples. The antimicrobial susceptibility profiles of the isolates to five drugs were examined, with 10 strains showing resistance to ampicillin, one strain showing resistance to erythromycin and one strain showing resistance to ciprofloxacin. Accordingly, penicillin-based antibiotics with a β-lactamase inhibitor are recommended for antimicrobial treatment for Capnocytophaga infections.
