oral bacterial infections, we investigated dog owners’ methods of caring for their dogs’
teeth and the characteristics of the microbial communities inhabiting the canine dental
surface.
The survey included 161 households whose dogs received physical examination at
the “Seoul Transport Physical Examination Center”. We found that dog owners’ home
oral care is insufficient to ensure their dogs’ proper dental health. Bacteria were isolated
from the dental surfaces of 119 dogs and identified using MALDI-TOF MS systems.
Among the 119 samples, 216 strains and 27 bacterial genera were identified. The
isolated bacterial genera in the order of abundance were Pasteurella spp.(23.6%),
Neisseria spp.(19.9%), Staphylococcus spp.(15.3%), and Streptococcus spp.(11.6%). In
addition, using the Columbia CNA agar culture method, bacteria were isolated from the
dental surfaces of 45 dogs. Among the 45 samples,
