C. canimorsus and C. cynodegmi are dog and cat commensals which can be 
transmitted to humans via bites or scratches and can cause sepsis, meningitis, 
endocarditis, and eye- or wound infections. Recently an additional 
Capnocytophaga species was identified as part of the oral flora of healthy dogs 
and was given the name "C. canis". We previously identified a Capnocytophaga 
isolate that could not be typed with available diagnostic tests including 
MALDI-TOF, 16S rRNA sequencing or species-specific PCR. This strain and 21 other 
Capnocytophaga spp isolated in Sweden from clinical blood- or wound-cultures 
were subjected to whole genome sequencing using the Illumina platform. 
Phylogenetic analysis revealed that the previously non-typable isolate belongs 
to the putative new species "C. canis". Since this strain was isolated from a 
wound it also shows that members of "C. canis" have the potential to be 
pathogenic. In addition, our phylogenetic analysis uncovered an additional 
species of Capnocytophaga, which can be transmitted from dogs and cats to 
humans, suggesting a speciation within the Capnocytophaga family that has not 
been observed before. We propose the name of "C. stomatis" for this putative 
novel species.
