Answer

Chlamydial infection can cause disease in many organ systems, including the genitourinary tract. Chlamydiae are small gram-negative obligate intracellular microorganisms that preferentially infect squamocolumnar epithelial cells. They include the genera Chlamydia (of which the type species is Chlamydia trachomatis) and Chlamydophila (eg, Chlamydophila pneumoniae and Chlamydophila psittaci).
