Abstract
The protein profiles of Porphyromonas gingivalis (ATCC 33277 and W83) bound to KB gingival epithelial cells were analyzed by SDS-PAGE and immunoblotti ng. We found that a 51-kDa component was formed in bacteria that adhered to the KB cells, whereas 26- to 29-kDa bands were less intensive, in contrast to the protein profile of free bacteria. P. gingivalis ATCC 33277 incubate d with protease-treated KB cells retained the profile of free bacteria. The se results demonstrate the specificity of bacterial recognition of eukaryot ic membrane components.
