Chlamydia trachomatis

Chlamydia trachomatis is a Gram-negative, anaerobic bacterium responsible for the sexually transmitted infection chlamydia and for trachoma, an eye disease. It exists in two forms, an infectious extracellular elementary body that attaches to and enters host cells, and a non-infectious intracellular reticulate body into which it transforms once inside a cell. The reticulate bodies replicate rapidly before converting back into elementary bodies, which are released to infect new host cells.
