Species/Subspecies: Chlamydia caviae
Etymology: Genus name: cloac loving.
Species epithet: of the guinea pig.
Significance:  [Of minor importance]   
Taxonomy:
Phylum
Chlamydiota
Class
Chlamydiia
Order
Chlamydiales
Family
Chlamydiaceae 
Genus
Chlamydia
Type Strain: GPIC = ATCC VR-813
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:
Chlamydia caviae  
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.
Reference(s): No. 68, 140, 177
