GTDB
id: s__Metamycoplasma canadense · GTDB R232
Exact taxid. Linked by NCBI taxid — GTDB records the same id NCBI does.
d__Bacteria;p__Bacillota_I;c__Bacilli_A;o__Mycoplasmatales;f__Metamycoplasmataceae;g__Metamycoplasma;s__Metamycoplasma canadense
Only 1 genome — below the threshold for detecting a split, so “current” here means unverified, not confirmed.
SILVA
Metamycoplasma canadense
id: U44769 · SILVA 138.2
Exact taxid. Linked by NCBI taxid — SILVA records the same id NCBI does.
Bacteria;Bacillota;Bacilli;Mycoplasmatales;Mycoplasmataceae;Mycoplasma;
Renamed: SILVA gives this taxon a different name in 132, 138, 138.1, 138.2.
Greengenes2
Metamycoplasma alkalescens
id: Metamycoplasma alkalescens · 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__Mycoplasmatales; f__Metamycoplasmataceae; g__Metamycoplasma; s__Metamycoplasma alkalescens
Only 2 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 4.2No 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.
