[Studies on the pleomorphism of trachoma inclusion].

A series of trachoma inclusion color photograph is taken from the conjunctival smears of 48 trachoma cases. These smears were Giemsa-stained and stored in the slide-boxes for more than 30 years with no distinct changes in color. A description is given to the Pleomorphism of trachoma inclusion and its relation to the host cells. According to the gradual morphological changes of Chlamydia trachomatis multiplied in the infected cells, a 5-staged classification for trachoma inclusions is provided which may be benefit to understanding the pleomorphism of the trachoma inclusion and clinical laboratory diagnosis.
