Species/Subspecies: Chlamydia muridarum
Etymology: Genus name: a cloac.
Species epithet: of the family mouse/hamster.
Significance:  [Of minor importance]   
Taxonomy:
Phylum
Chlamydiae
Class
Chlamydiia
Order
Chlamydiales
Family
Chlamydiaceae 
Genus
Chlamydia
Type Strain: MoPn = ATCC VR-123
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). C. muridarum is 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:Respiratory infection in rodents.
Hosts: Rodents

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.
Comment:Members of the family Chlamydiaceae are obligately intracellular. The cell envelope contains cystein rich proteins and only a small amount of peptidoglycans.
