id: s__Blautia sp900541955 / s__Blautia hansenii · GTDB R232
Database's species id. At its weakest, linked by GTDB's own NCBI species id rather than the genome's raw one.

Warning: GTDB R232 places this taxon's 28 genomes in 2 species.
Renamed: GTDB gives this taxon a different name in R207, R214, R220, R226, R232.
SILVA
Blautia hansenii
id: AB534168 · SILVA 138.2
Walked up to species. At its weakest, linked by walking up 1 level from a strain or subspecies record to the species.

Greengenes2
Blautia_A_141780 hansenii
id: Blautia_A_141780 hansenii · 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_141780; s__Blautia_A_141780 hansenii
Only 1 genome — 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 4.2No 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.
