Genera

The Chlamydiaceae are a family of

ribosomal RNA genes all have at least 90% DNA sequence identity. Chlamydiaceae species have varying inclusion morphology, varying extrachromosomal plasmid
content, and varying sulfadiazine resistance.

The family Chlamydiaceae currently includes one genus and one candidate genus: Chlamydia and candidatus Clavochlamydia.[1]

Chlamydia

Three species belong to Chlamydia:

ribosomal operons
.

Chlamydia trachomatis is the cause of an infection commonly

transmitted sexually (often referred as just "Chlamydia") and also is the cause of trachoma
, an infectious eye disease, spread by eye, nose, and throat secretions.

Phylogeny
