GTDB

Release

Megasphaera micronuciformis

id: s__Megasphaera micronuciformis · 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__Negativicutes;o__Veillonellales;f__Megasphaeraceae;g__Megasphaera;s__Megasphaera micronuciformis

Renamed: GTDB gives this taxon a different name in R207, R214, R220, R226, R232.

SILVA

Release

Megasphaera micronuciformis

id: KC632239 · SILVA 138.2

Walked up to species. At its weakest, linked by walking up 2 levels from a strain or subspecies record to the species.

No record in Greengenes2 2024.09.

eHOMD

Release 4.2

Megasphaera micronuciformis

id: HMT-122 · eHOMD 4.2

Exact taxid. 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.
