Chlamydia trachomatis is a gram-negative ovoid bacterium, known for its role in causing the sexually transmitted Chlamydia infection. It transmits through bodily secretions, generally infecting mucosal membranes such as those in the cervix, urethra, rectum, throat, and eyes. It triggers endocytosis within the host cells and incubates inside for about 7 to 21 days, before release by exocytosis. C. trachomatis has a 1 Mbp genome encoding over 800 proteins.
