|Category:||Notifiable diseases and bacteria|
|Etymology:||Genus name: cloac loving. |
Species epithet: of abortion.
|Alternative Species Name(s):||Chlamydia psittaci|
|Type Strain:||B577 = ATCC VR-656.|
|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:||Enzootic abortion of ewes, ovine chlamydiosis.
|Hosts:||Cattle, sheep, goat, pig|
|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.|
|Legislation:||The disease in cattle and sheep is notifiable (to the Swedish Board of Agriculture) in Sweden.|
|Comment:||Strictly intracellular. The cell envelope contains cystein rich proteins and only a small amount of peptidoglycans.|
|Reference(s):||No. 68, 140|

|The revised taxonomy of the mollicutes|
The revised taxonomy of mollicutes (mycoplasmas) has now been introduced on VetBact, which means that many of the species have been given new genus names or moved to another higher taxon.Published 2021-11-25. Read more...
