| Species/Subspecies: | Chlamydophila abortus | ||||||||
|---|---|---|---|---|---|---|---|---|---|
| Category: | Notifiable diseases and bacteria | ||||||||
| Etymology: | Genus name: cloac loving. Species epithet: of abortion. | ||||||||
| Significance: | [Important] | ||||||||
| Old Species Name(s): | Chlamydia psittaci | ||||||||
| Taxonomy: | Class Chlamydiia Order Chlamydiales Family Chlamydiaceae Genus Chlamydophila |
||||||||
| 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. | ||||||||
| Catalase/Oxidase: | |||||||||
| Spec. Char.: | |||||||||
| Disease: | Enzootic abortion of ewes, ovine chlamydiosis. |
||||||||
| Hosts: | Cattle, sheep, goat, pig | ||||||||
| Clinical Picture: | Abortion | ||||||||

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