Species code:	CHLTR
Taxonomy:	Bacteria; Chlamydiae; Chlamydiales; Chlamydiaceae; Chlamydia (TaxID: 813) [NEWT/ NCBI]
Description:	Chlamydia trachomatis infection is an important cause of preventable blindness and sexually transmitted disease (STD) in humans. There are 15 serovariants that exhibit distinct organotropism for the eye or the urogenital tract and are separated according to the pathobiotypes. Trachoma biovariants consist of serovars A, B, Ba, C, D, E, F, G, H, I, J and K. LGV (Lymphogranuloma venereum) biovariants consist of serovars L1, L2 and L3. Trachoma biovariants are noninvasive and epitheliotropic strains that cause blinding trachoma (A to C) or sexually transmitted diseases. LGV biovariants cause sexually transmitted diseases with disseminating infection of draining regional lymph nodes. The trpBA operon encoding tryptophan synthase is functional in STD serovars, whereas trpBA harbors mutations that inactivate the enzyme in ocular serovars. Chlamydia trachomatis is an obligate intracellular parasite depending on the host machinery for ATP synthesis. Chlamydial life cycle comprehends an intracellular metabolically- active "reticular body" and an inert extracellular spore-like "elementary body" equipped with a unique disulfide-cross-linked protein envelope. Chlamydia trachomatis (strain D/UW-3) is a genitotropic isolate.
