Bacterial alpha and beta diversity of chronically diseased tissue and adjacent tissue. (A) Bacterial community composition profiles illustrate abundances of prevalent taxonomic classes. All taxa unassigned at the kingdom level were removed. Patients are arbitrarily labeled A through I with chronically diseased tissue (DT) and adjacent tissue (AT) indicated. (B) Venn diagram of core microbiome (including OTUs found in ≥80% of the samples) presents the number of OTUs that are shared (66.0%) and unique between chronically diseased tissue (DT) (18.9%) and adjacent tissue (AT) (15.1%).
