| Species/Subspecies: | Chlamydia abortus | ||||||||
|---|---|---|---|---|---|---|---|---|---|
| Category: | Notifiable diseases and bacteria | ||||||||
| Etymology: | Genus name: cloac loving. Species epithet: of abortion. | ||||||||
| Significance: | [Important] | ||||||||
| Alternative Species Name(s): | Chlamydia psittaci | ||||||||
| Taxonomy: | Class Chlamydiia Order Chlamydiales Family Chlamydiaceae Genus Chlamydia |
||||||||
| 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. | ||||||||

| Taxonomy/phylogeny:
|
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. | ||||||||
| 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. | ||||||||
