Chlamydia trachomatis

Chlamydia trachomatis, an obligate intracellular human pathogen, is one of three bacterial species in the genus Chlamydia. C. trachomatis is Gram-indeterminate (i.e. cannot be stained with the Gram stain); structurally the organism is Gram-negative. Identified in 1907, C. trachomatis was the first chlamydial agent discovered in humans.

C. trachomatis includes three human biovars: trachoma (serovars A, B, Ba or C), urethritis (serovars D-K), and lymphogranuloma venereum (LGV, serovars L1, 2 and 3). Many, but not all, C. trachomatis strains have an extrachromosomal plasmid.
