Figure 4. Non-bacterial members of the metagenomes of periodontal health and disease.

Distribution of viral species by sample is shown in (A) and viral genes in (B). Relative abundances of species belonging to the archaebacterial kingdom in each sample is shown in (C,D) shows the distribution of species belonging to the fungal kingdom by sample. Genes and taxa that were significantly different between deep-diseased and shallow-healthy sites (p < 0.05, FDR adjusted Wald test) are indicated by an asterisk (*) in the legend.
