Causative Agents
Chlamydia trachomatis is one of three Chlamydia species (Chlamydia pneumoniae and Chlamydia psittaci) which are human pathogens. The bacteria mainly cause sexually transmitted disease (STDs) and trachoma. While the genovars A, B, Ba and C result trachoma; LGV-I,-II and –III result lymphogranuloma (LGV) and genovars D and K result oculogenital disease. Chlamydia trachomatis’ genome is 1,042,519 base pairs long with 894 predicted protein-coding sequences. (1, 2)
