Fig 2. The feline construal of the core microbiota in health and mild periodontitis figure from Abusleme et al. (2013).
OTUs were defined as part of the core microbiota if they represented ≥0.5% of sequence reads in at least 50% of samples. If they were equally prevalent and abundant in healthy and mild periodontitis samples they formed part of the core microbiota (grey rectangles). If they were more prevalent and abundant in healthy samples they formed part of the healthy core (green ovals). If they were more prevalent and abundant in mild periodontitis samples they formed part of the mild periodontitis core microbiota (red ovals). Relative prevalence and abundance data were used for further sub-division. Ovals labelled with 1 contain highly prevalent (≥2/3rd of samples) and highly abundant OTUs (≥2% of sequences). Ovals labelled with 2 contain highly prevalent (≥2/3rd of samples) with lower abundances (<2% of sequences). Ovals labelled with 3 contain less but still highly prevalent OTUs (≥1/2 and <2/3rd of samples).
