  1. a - sum of all samples of three individuals; only sequences that were present at least 5 times are included
  2. b - number of unique sequences that were common in all three microbiomes
  3. c - number of all OTUs (sequences that clustered at 3% genetic difference)
  4. d - number of OTUs (sequences clustered at 3% genetic difference) that were common in all three microbiomes
