GTDB
id: s__Chlamydia pneumoniae · 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 pneumoniae
Renamed: GTDB gives this taxon a different name in R207, R214, R220, R226, R232.
SILVA
Chlamydia pneumoniae
id: U68426 · 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;Chlamydiota;Chlamydiia;Chlamydiales;Chlamydiaceae;Chlamydia;
Renamed: SILVA gives this taxon a different name in 132, 138, 138.1, 138.2, 144.
Greengenes2
No record in Greengenes2 2024.09.
eHOMD
Release 4.2Chlamydia pneumoniae
id: HMT-733 · eHOMD 4.2
Exact taxid. Linked by NCBI taxid — eHOMD records the same id NCBI does.
Bacteria;Chlamydiota;Chlamydiia;Chlamydiales;Chlamydiaceae;Chlamydia
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.
