GTDB

Release

Streptococcus downei

id: s__Streptococcus downei · GTDB R232

Database's species id. At its weakest, linked by GTDB's own NCBI species id rather than the genome's raw one.

d__Bacteria;p__Bacillota;c__Bacilli;o__Lactobacillales;f__Streptococcaceae;g__Streptococcus;s__Streptococcus downei

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

SILVA

Release

Streptococcus downei

id: AY188350 · 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.

Bacteria;Bacillota;Bacilli;Lactobacillales;Streptococcaceae;Streptococcus;

Greengenes2

Release

Streptococcus sobrinus

id: Streptococcus sobrinus · Greengenes2 2024.09

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

d__Bacteria; p__Bacillota_I; c__Bacilli_A; o__Lactobacillales; f__Streptococcaceae; g__Streptococcus; s__Streptococcus sobrinus

Only 4 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

Streptococcus downei

id: HMT-594 · eHOMD 4.2

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

Bacteria;Bacillota;Bacilli;Lactobacillales;Streptococcaceae;Streptococcus

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.
