*1.2.9 Conjunctivitis*

Serovars D through K of *C. trachomatis* can cause genital disease in the conjunctival epithelium. The most common method for achieving this goal is directly inoculating infected genital secretions. Inclusion conjunctivitis, which may appear cobbled, is a typical presentation of sexually acquired chlamydial conjunctivitis. Serovars A through C cause endemic trachoma, but this type of infection differs.

#### *1.2.10 Pharyngitis*

There is no evidence that *C. trachomatis* is a significant cause of pharyngitis. However, nucleic acid amplification testing has detected C trachomatis in the pharynx, and some investigators believe this site serves as a reservoir for the infection.
