Chlamydia trachomatis cytotoxicity associated with complete and partial cytotoxin genes.

ABSTRACT: Chlamydia trachomatis is an obligate intracellular human bacterial pathogen that infects epithelial cells of the eye and genital tract. Infection can result in trachoma, the leading cause of preventable blindness worldwide, and sexually transmitted diseases. A common feature of infection is a chronic damaging inflammatory response for which the molecular pathogenesis is not understood. It has been proposed that chlamydiae have a cytotoxic activity that contributes to this pathology, but a toxin has not been identified. The C. trachomatis genome contains genes that encode proteins with significant homology to large clostridial cytotoxins. Here we show that C. trachomatis makes a replication-independent cytotoxic activity that produces morphological and cytoskeletal changes in epithelial cel
