|Etymology:||Genus name: cloac loving.|
Species epithet: ofpneumonia.
|Old Species Name(s):||Chlamydia pneumoniae|
|Type Strain:||ATCC VR-2282|
|Macromorphology (smell):||Does only grow intracellularly and can, therfore, not be cultivated on artificial substrates.|
|Micromorphology:||infectious elementary bodies (0.2-0.3 µm).
Within the host cell: non-infectious reticulate bodies (0.8-1.0 µm). C. pneumoniae is 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:||Humans: respiratory infection.
Horse: respiratory infection.
Koalas: eye infection.
|Hosts:||Humans (and horse and koala)|
|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.|

For a long time, Rhodococcus hoagii was referred to Rhodococcus equi on VetBact, because we experienced some resistance to the name that is now considered to be the correct one, i.e. Rhodococcus hoagii. Now you can find the bacterium in question under the correct name in VetBact, but you can also find the bacterium when searching for the old name.Published 2021-10-10. Read more...
