Figure 6From: Bacterial community composition of chronic periodontitis and novel oral sampling sites for detecting disease indicatorsBubble plot of indicator OTUs associated with health and disease. Each bubble represents an OTU identified by Dufrêne-Legendre indicator species analysis as being associated with health (green) or disease (pale red). (A) Pooled SupG, SubG, and tongue samples; (B) SubG samples; (C) SupG samples; and (D) tongue samples. Bubble area is proportional to OTU sequence abundance. Only OTUs with indicator values >0.5 and taxa with a total of ≥100 sequences are shown. Complete indicator OTU lists are available in Additional file 7.Back to article page
