Atlantic Canadian oral microbiome composition is dominated by the genus Veillonella and is relatively similar at the genus level but highly variable at the ASV level. Samples were from the Atlantic Partnership for Tomorrow’s Health project (n = 1,049). Samples were subsampled to a depth of 5,000 reads. (A) Genera that had a mean relative abundance of less than 1% were grouped into “Other.” (B) Genera were removed at different sample presence cutoffs, and the remaining total mean relative abundance of nonfiltered genera was then calculated. (C) ASVs were removed at different sample presence cutoffs, and the remaining total mean relative abundance of nonfiltered ASVs was then calculated.
