GTDB
Chlamydia psittaci
id: s__Chlamydia psittaci · 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__Chlamydiota;c__Chlamydiia;o__Chlamydiales;f__Chlamydiaceae;g__Chlamydia;s__Chlamydia psittaci
Renamed: GTDB gives this taxon a different name in R207, R214, R220, R226, R232.
SILVA
Chlamydia psittaci
id: AB001778 · 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.

Greengenes2
Chlamydophila abortus
id: Chlamydophila abortus (+1) · Greengenes2 2024.09
Genome accession. Linked via GTDB R220 genome accessions — the same physical genomes, not a name match.
d__Bacteria; p__Chlamydiota; c__Chlamydiia; o__Chlamydiales_778489; f__Chlamydiaceae; g__Chlamydophila; s__Chlamydophila abortus
Only 2 genomes — below the threshold for detecting a split, so “current” here means unverified, not confirmed.
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.
