The cytolethal distending toxin (CDT) of Actinobacillus actinomycetemcomitans is a typical member of this Gram-negative bacterium holotoxin family that targets a wide spectrum of eukarytotic cells, typically causing cell cycle arrest at either the G(1) or G(2)/M phase of the cell cycle. In view of the possible role of the CDT as a prominent A. actinomycetemcomitans virulence factor in periodontal diseases, we have examined the effects of the toxin on primary cultures of human periodontal ligament fibroblasts (HPLF).
