Species/Subspecies: Chlamydia suis
Etymology: Genus name: a cloac.
Species epithet: of a pig.
Significance:  [Of minor importance]   
Taxonomy:
Phylum
Chlamydiota
Class
Chlamydiia
Order
Chlamydiales
Family
Chlamydiaceae 
Genus
Chlamydia
Type Strain: S45 = ATCC VR-1474.
Macromorphology (smell):
Micromorphology: Utanför värdcellen: infektiösa elementarkroppar (0,2-0,3 µm).
I värdcellen: icke-infektiösa retikulärkroppar (0,8-1,0 µm). C. trachomatis är orörlig.
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:Enteric infections
Hosts: Pig
Clinical Picture:
16S rRNA Seq.:
Acc-noStrainNumber of NTOperon
U73110 S45T 1545  

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.
Comment:Strictly intracellular. The cell envelope contains cystein rich proteins and only a small amount of peptidoglycans.
Reference(s): No. 68, 140, 177
