1Typically, clones with >94% 16S rRNA gene identity to the
nearest cultivated relative were considered members of that genus.2Clones grouped with the Prevotella genus had 92–94% 16S rRNA gene
identity to their closest cultivated relative.3Operational
taxonomic units (OTUs) were calculated at a cutoff of 97% similarity.
