Trachoma is primarily caused by Chlamydia serotypes which of the following?

Explanation:
Trachoma is caused by the ocular serovars of Chlamydia trachomatis, specifically the serovars A, B, Ba, and C. These strains preferentially infect ocular tissue and drive the chronic follicular conjunctivitis, scarring, and potential eyelid deformities characteristic of trachoma. In contrast, serovars D through K are mainly associated with genital infections and adult inclusion conjunctivitis, while L1 through L3 cause lymphogranuloma venereum. Therefore, the serotypes linked to trachoma are the ocular ones (A, B, Ba, and C).
