A.actinomycetemcomitans cells secrete synthetic cytolethal distending toxin(CDT) and outer membrane protein(OMP), which can be easily planted into the host to destroy immunity function. Thus, the presence of these molecules leads to the progression of periodontal tissue destruction and periodontal diseases. This paper mainly describes the structural function and pathogenic mechanism of the two virulence factors, namely, CDT and OMP, for further research.<br>中图分类号
