aThe order of appearance of the three Domains of life is defined by the taxon with the highest PHI-Blast bit score. The taxa of a given Domain are then listed by decreasing bit score. Strains/isolates are indicated.
bTaxa with bit score ≥ 90 in the initial PHI-Blast (see Methods section) are listed here. additional file 2, Table S2 has the complete taxa and sequences accessions list. The listed eukaryotes and Archaea were the only taxa recovered in the search. The numbers in brackets are the corresponding numbers of hits from a PSI-Blast search - two iterations with e-score ≤ 1e-5 following the aforementioned PHI-Blast search. The complete list of taxa and sequences accessions for the PSI-Blast search are in additional file 3, Tables S3 (Trichomonas and Entamoeba) and additional file 9, Table S6 (Bacteria and Archaea).
cTaxa isolated from human tissues might be present in other mammalian species as well. HMP: indicates species being sequenced in the context of the Human Microbiome Project [101].
