Taxa summary of ‘core’ OTUs identified in 95% of samples (n = 20) that underwent sequencing of the V2-V3 region of the 16S rRNA gene. The figure depicts the relative contribution of each member of the ‘core’ community to each sample in addition to its overall contribution to the core community over all samples combined. The contribution of taxa to the core community is expressed as a percentage. The letter A next to the patient ID denotes “adjacent” tissue and M denotes “malignant” tissue. The letters in the taxonomy column refer to k – kingdom, p – phylum, c –class, o –order, f – family, g – genus, s – species
