Warning: GTDB R232 places this taxon's 584 genomes in 3 species.
SILVA
Clostridium botulinum
id: JN617053 · SILVA 138.2
Walked up to species. At its weakest, linked by walking up 3 levels from a strain or subspecies record to the species.

eHOMD
Release 4.2No 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.
