Etymology: Chlamydia trachomatis is a bacterium named in the late nineteenth and early twentieth century from Greek roots, not an ancient term. The genus name "Chlamydia" was coined in 1907 by Ludwig Halberstaedter and Stanislaus von Prowazek, who gave it the name from Greek "chlamys," a short cloak, because the cell-inclusions they observed looked like cloaks draped over the host cell's nucleus. Its species epithet, "trachomatis," comes from Greek "trachoma," meaning a rough or granular condition, which is also the root of the eye disease trachoma, the infection that the bacterium was later found to cause in the eye. The grainy appearance that gave trachoma its name refers to the rough, raised granules that form on the inner surface of the eyelid during infection. Trachoma, from Greek "trachys," rough, was a long-recognised disease of the eye, and the name was transferred to the bacterium once it was linked to that condition. The species name therefore records a clinical observation rather than a discovery about the organism's shape or behaviour.
