Description
The Chlamydiaceae are a family of Gram-negative bacteria that belongs to the phylum Chlamydiae, order Chlamydiales.
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.
C. 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.
