GTDB
Klebsiella pneumoniae
id: s__Klebsiella pneumoniae · GTDB R232
At its weakest, linked by GTDB's own NCBI species id rather than the genome's raw one.

SILVA
Klebsiella pneumoniae
id: AB004753 · SILVA 138.2
Linked by name — the SILVA table we ingest carries no NCBI taxid, so the binomial is the only join.

- Klebsiella granulomatis
- Kluyvera georgiana
- +8 more — see all names below
id: Klebsiella granulomatis / Kluyvera georgiana (+8) · Greengenes2 2024.09
Linked via GTDB R220 genome accessions — the same physical genomes, not a name match.
d__Bacteria; p__Pseudomonadota; c__Gammaproteobacteria; o__Enterobacterales_737866; f__Enterobacteriaceae_A_725029; g__Klebsiella_724518; s__Klebsiella granulomatis
Warning: Greengenes2 2024.09 places this taxon's 2056 genomes in 2 species.
Name differs between releases: Name differs across Greengenes2 releases.
eHOMD
release 4.2Klebsiella pneumoniae
id: HMT-731 · eHOMD 4.2
Linked by NCBI taxid — eHOMD records the same id NCBI does.

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.
