Veterinary bacteriology: information about important bacteria
|Category:||Primarily of interest in human medicin|
|Etymology:||Genus name: cloac loving.|
Species epithet: ofpneumonia.
|Alternative 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.:|
||Species within the family Chlamydiaceae were previously (1999) divided into two genera Chlamydia and Chlamydophila. However, the differences between these two genera were not that great and many research groups have not accepted this division. Therefore, the genus Chlamydophila has been returned (2015) to the genus Chlamydia. See the references below.|
|Comment:||Members of the family Chlamydiaceae are obligately intracellular. The cell envelope contains cystein rich proteins and only a small amount of peptidoglycans.|
