Table I: Bacteria compositions of human microbiota #HuA and #HuB from two healthy donors.

Shown are bacteria species in microbiota #HuA and #HuB; bacteria species were identified using MALDI-TOF mass spectrometry (Bruker Biotyper) and 16S rDNA amplicon Sanger sequencing. Four bacteria species, Bacteroides ovatus, Bacteroides thetaiotanomicron, Bacteroides uniformis and Eggerthella lenta, are common in both microbiotas. The majority of the bacteria species (6 out of 10 of microbiota #HuA and 16 of 20 of micriobiota#HuB) are unique among the two microbiota.
