GTDB

Release

Porphyromonas circumdentaria

id: s__Porphyromonas circumdentaria · GTDB R232

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

d__Bacteria;p__Bacteroidota;c__Bacteroidia;o__Bacteroidales;f__Porphyromonadaceae;g__Porphyromonas;s__Porphyromonas circumdentaria

Only 3 genomes — below the threshold for detecting a split, so “current” here means unverified, not confirmed.

SILVA

Release

Porphyromonas circumdentaria

id: L26102 · SILVA 138.2

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

Greengenes2

Release

Porphyromonas_A gingivicanis

id: Porphyromonas_A gingivicanis · Greengenes2 2024.09

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

d__Bacteria; p__Bacteroidota; c__Bacteroidia; o__Bacteroidales; f__Porphyromonadaceae; g__Porphyromonas_A; s__Porphyromonas_A gingivicanis

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 4.2

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.
