|Etymology:||Genus name: cloac loving. |
Species epithet: of cat.
|Alternative Species Name(s):||Chlamydophila psittaci|
|Type Strain:||FP Baker = ATCC VR-120.|
|Macromorphology (smell):||Does only grow intracellularly and can, therfore, not be cultivated on artificial substrates.|
|Micromorphology:||Outside the host cell: infectious elementary bodies (0.2-0.3 µm).
Within the host cell: non-infectious reticulate bodies (0.8-1.0 µm). Non-motile.
|Gram +/Gram -:||G-, difficult to gram stain|
|Metabolism:||Aerobic, but members of the family Chlamydiaceae have only limited resources to to synthesize their own ATP. Therefore, they can ingest ATP from the host cell.|
|Disease:||Eye and airway infections
|16S rRNA Seq.:|
||Five species have been described within genus Chlamydia and six species have been described within genus Chlamydophila. Species within the family Chlamydiaceae form two relatively distinct clusters and have, therefore, been divided into two genera Chlamydia and Chlamydophila. However, some research groups have not accepted this, but include all species within genus Chlamydia.|
|Comment:||Members of the family Chlamydiaceae are obligately intracellular. The cell envelope contains cystein rich proteins and only a small amount of peptidoglycans.|

|New names of taxa within the classification category phylum|
During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.Published 2022-09-28.
