id: s__Ruminococcoides intestinale / s__Hominimerdicola aceti / s__Ruminococcoides intestinale_A · GTDB R232

Exact taxid. Linked by NCBI taxid — GTDB records the same id NCBI does.

GTDB R232 places this taxon's 1273 genomes in 5 species.

Renamed: GTDB gives this taxon a different name in R207, R214, R220, R226, R232.

SILVA

Release

No record in SILVA 138.2.

Greengenes2

Release

Blautia_A_141781 obeum

id: Blautia_A_141781 obeum · Greengenes2 2024.09

Genome accession. Linked via GTDB R220 genome accessions — the same physical genomes, not a name match.

d__Bacteria; p__Bacillota_A_368345; c__Clostridia_258483; o__Lachnospirales; f__Lachnospiraceae; g__Blautia_A_141781; s__Blautia_A_141781 obeum

Only 2 genomes — below the threshold for detecting a split, so “current” here means unverified, not confirmed.

Renamed: Greengenes2 gives this taxon a different name in 2022.10, 2024.09.

eHOMD

Release 4.2

No record in eHOMD 4.2.

Each panel shows one release. Switch a release to see how that database's answer changes — the taxon is held fixed by NCBI taxid, so every panel describes the same organism. Each panel also says how it was linked; how the databases are joined explains the routes.

Each column is the release its box shows. marks the first rank at which a database's name differs from NCBI's, by exact text; a suffix such as _A counts. SILVA's path and eHOMD's columns end at genus, so their species row is blank; the box above names the species. Levels a source labels outside these seven ranks are in the API's ranks and not drawn here.
