DNA were extracted from buccal cell samples using the PowerSoil Pro kit (MoBio Laboratories, Inc.). The extracted DNA were then sent to BGI Genomics, where pair-ended whole metagenome shotgun sequencing was performed using a minimum of 300 nanograms (ng) of DNA via the Illumina HiSeq2000 platform with a read length of 100 base pairs (bp) (insert size 350 bp).
