Abstract excerpt
A total of 188 Porphyromonas gingivalis strains isolated from 13 periodontal pockets of 8 periodontitis patients were investigated by means of restriction fragment length polymorphism (RFLP) analysis using the fimA gene as a pobe. A total of 5 RFLP genotypes were identified, and over half of the isolates belonged to type I. Four of the 8 patients harbored only 1 RFLP genotype of P. gingivalis, and 1 patient...
