“…Therefore, the increased abundance of these species may be considered as potential periodontitis salivary bacterial biomarkers. In this context, while M. edwardii have been depicted as pathogen of the respiratory tract in dogs (Jambhekar et al 2019 , Alves et al 2023 ), various species belonging to the genus Elizabethkingia have been recognized as emerging pathogens responsible of various septicemia cases (Bordelo et al 2016 , Zajmi et al 2022 , Weese et al 2023 ). At the same time, a member of the genus Fusobacterium with a high abundance in the human oral cavity, i.e.…”

Periodontal diseases are among the most common bacterial-related pathologies affecting the oral cavity of dogs. Nevertheless, the canine oral ecosystem and its correlations with oral disease development are still far from being fully characterized. In this study, the species-level taxonomic composition of saliva and dental plaque microbiota of 30 healthy dogs was investigated through a shallow shotgun metagenomics approach. The obtained data allowed not only to define the most abundant and prevalent bacterial species of the oral microbiota in healthy dogs, including members of the genera Corynebacterium and Porphyromonas, but also to identify the presence of distinct compositional motifs in the two oral micro-niches as well as taxonomical differences between dental plaques collected from anterior and posterior teeth. Subsequently, the salivary and dental plaque microbiota of 18 dogs affected by chronic gingival inflammation and 18 dogs with periodontitis were compared to those obtained from the healthy dogs. This analysis allowed the identification of bacterial and metabolic biomarkers correlated with a specific clinical status, including members of the genera Porphyromonas and Fusobacterium as microbial biomarkers of a healthy and diseased oral status, respectively, and genes predicted to encode for metabolites with anti-inflammatory properties as metabolic biomarkers of a healthy status.
