OBJECTIVE: To compare the ability of adhesion and invasion to epithelial cells by Porphyromonas gingivalis (Pg) strains with different fimA separated from Chinese.
METHODS: Cultured method and antibiotic protection method were used to determine the adhesive and invasive ability of Pg with different fimA genetypes. The adhesion was observed by scanning electron microscope.
RESULTS: All the strains adhered and invaded to KB cells, and the adhesion rate ranged from 0.523% to 37.125% and invasive rate from 0.017% to 3.750%.The adhesive and invasive ability among different fimA genotypes showed no significant difference (P > 0.05).
CONCLUSIONS: There is no significant correlation between fimA genotype and ability in adhesion and invasion to KB cells.
