Detection of Periodontal Pathogens from Dental Plaques of Dogs with and without Periodontal Disease.

Dental plaque bacteria are one of the main factors responsible for the development of a periodontal disease, which is the most common infectious disease in dogs. The aim of this study was to identify the presence of periodontal disease-related bacteria in the dental plaque of dogs. Plaque samples were taken from dogs with and without periodontal disease. Samples were analyzed for the presence of , and using a PCR technique amplifying 16S rRNA genes of and and genes of species, including . The presence of was confirmed in all samples. was detected in all dogs with periodontal disease and in 71.43% of dogs without periodontal disease. spp. were detected in 64.29% of the samples. Based on Sanger sequencing and Basic Local Alignment Search Tool algorithm, spp. were identified as and . was present in 28.57% of dogs with periodontal disease, while was present in 42.86% of dogs with periodontal disease and in 57.14% of dogs without periodontal disease. was positively correlated with both and , suggesting that it may be involved in the development of periodontal disease.
