Research Abstract |
In order to gain insight into the mechanism and significance of host cell invasion by periodontal bacteria in polymicrobial infecti on, we assessedPorphyromonas gingivalis invasion of gingival epithelial cells enhanced by Fusobacterium nucleatum. Confocal scanning laser microscopy and antibiotic protection assay were used to study the role of P. gingivalis invasin (SerB) in this phenomena. The results from the experiment using SerB-mutant strain showed that the P. gingivalis invasin does not play a major role in this phenomenon. It was demonstrated that lipid raft was involved in fusobacterial enhancement of P. gingivalis invasion.
