As Clamidiáceas (Chlamydiaceae) é unha familia de bacterias que pertencen ao filo Chlamydiae, orde Chlamydiales. Todas as especies de Chlamydiaceae son Gram negativas e expresan un epitopo lipopolisacárido específico da familia chamado αKdo-(2→8)-αKdo-(2→4)-αKdo (previamente denominado epitopo específico de xénero). Os xenes do ARN ribosómico de todas Chlamydiaceae teñen polo menos unha identidade de secuencia do 90% no seu ADN. As especies de Chlamydiaceae teñen unha variada morfoloxía de inclusión, variado contido doplásmido extracromosómico, e diferente resistencia á sulfadiazina.

Chlamydiaceae currently includes two genera and one candidate genus: Chlamydia, Chlamydophila and Candidatus Clavochlamydia.

Chlamydia

Artigo principal: Chlamydia (bacterium).

Three species belong to Chlamydia: C. trachomatis, C. muridarum, and C. suis. C. trachomatis has been found only in humans, C. muridarum in hamsters and mice (family Muridae), and C. suis in swine. Chlamydia spp. produce a small amount of detectable glycogen and have two ribosomal operons.

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

Chlamydophila

Six species belong to Chlamydophila: C. pneumoniae (often also called Chlamydia pneumoniae), C. pecorum, C. psittaci, C. abortus, C. caviae, and C. felis. Chlamydophila spp. do not produce detectable glycogen and have one ribosomal operon. These species are naturally found living in a variety of animals.
