  • aChao’s nonparametric total diversity estimates are given. Phylotypes are grouped based on the degree of sequence identity in the V2 regions of their 16S rRNA genes.

  • TS28- and TS29-Deep, deeply sequenced cotwin fecal samples; TS28- and TS29-Shallow, shallow sequenced cotwin fecal samples; TSAll-Shallow, 1,000 randomly selected sequences from 250 fecal samples; TSAll-Co-occur, restricted to co-occurring sequences from 250 fecal samples; WholeBody, 250 randomly selected samples from a total of 814 samples obtained from 27 body sites from 9 individuals, 1,000 sequences/sample).
