GTDB

Release

Fusobacterium_A necrogenes

id: s__Fusobacterium_A necrogenes · GTDB R232

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

d__Bacteria;p__Fusobacteriota;c__Fusobacteriia;o__Fusobacteriales;f__Fusobacteriaceae;g__Fusobacterium_A;s__Fusobacterium_A necrogenes

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

SILVA

Release

Fusobacterium necrogenes

id: X55408 · SILVA 138.2

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

Greengenes2

Release

Fusobacterium_A mortiferum

id: Fusobacterium_A mortiferum · Greengenes2 2024.09

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

d__Bacteria; p__Fusobacteriota; c__Fusobacteriia; o__Fusobacteriales; f__Fusobacteriaceae; g__Fusobacterium_A; s__Fusobacterium_A mortiferum

Only 3 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.
