Size of the 95% core microbiome by body site.

Abstract

<p>The oral cavity sites show the greatest number of core OTUs with both the V1–V3 and the V3–V5 tags, followed by the stool, the anterior nares, then the skin and the vaginal sites. Core OTUs are defined as those OTUs appearing in at least 95% of all samples for a given body site. Body site labels in order are: saliva (SV), supragingival plaque (SUPP), hard palate (HP), palatine tonsils (PT), tongue dorsum (TD), throat (TH), buccal mucosa (BM), subgingival plaque (SUBP), keratinized gingiva (KG), anterior nares (AN), stool (ST), right (RAF) and left (LAF) antecubital fossae, left (LRC) and right (RRC) retroauricular creases, posterior fornix (PF), mid-vagina (MV), and vaginal introitus (VI).</p
