- +8 more — see all names below
id: s__Bifidobacterium longum / s__Bifidobacterium infantis · GTDB R232
At its weakest, linked by GTDB's own NCBI species id rather than the genome's raw one.
d__Bacteria;p__Actinomycetota;c__Actinomycetes;o__Actinomycetales;f__Bifidobacteriaceae;g__Bifidobacterium;s__Bifidobacterium longum
Warning: GTDB R232 places this taxon's 1305 genomes in 2 species.
SILVA
Bifidobacterium longum
id: JN656707 · SILVA 138.2
Linked by name — the SILVA table we ingest carries no NCBI taxid, so the binomial is the only join.
Bacteria;Actinomycetota;Actinobacteria;Bifidobacteriales;Bifidobacteriaceae;Bifidobacterium;
Name differs between releases: Name differs across SILVA releases.
Greengenes2
Bifidobacterium longum
id: Bifidobacterium longum (+2) · Greengenes2 2024.09
Linked via GTDB R220 genome accessions — the same physical genomes, not a name match.
d__Bacteria; p__Actinomycetota; c__Actinomycetes; o__Actinomycetales; f__Bifidobacteriaceae; g__Bifidobacterium_388775; s__Bifidobacterium longum
eHOMD
release 4.2Bifidobacterium longum
id: HMT-862 · eHOMD 4.2
Linked by NCBI taxid — eHOMD records the same id NCBI does.
Bacteria;Actinomycetota;Actinomycetes;Bifidobacteriales;Bifidobacteriaceae;Bifidobacterium
Only 1 genome — below the threshold for detecting a split, so “current” here means unverified, not confirmed.
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.
