Prevalence of F. alocis. (a): Prevalence of F. alocis in all of the samples collected from GAP patients, CP patients and PR subjects as determined by dot blot hybridization using oligonucleotide probes. (b): Prevalence of F. alocis (F. a.), P. gingivalis (P. g.), P. intermedia (P. i.), A. actinomycetemcomitans (A. a.), T. denticola (T. d.), T. forsythia (T. f.), and F. nucleatum (F. n.) in the deepest pocket of each patient. Asterisks (*) indicate statistically significant differences (p < 0.05) between the GAP and PR groups. Crosses (†) indicate statistically significant differences (p < 0.05) between the CP and PR groups. (c): Percentage of samples positive for F. alocis at probing pocket depths 4-6 mm and 7-9 mm. Statistical analysis was limited to one pocket per patient and depth group. Asterisks (*) indicate statistically significant differences (p < 0.05) between the GAP and PR groups. Crosses (†) indicate statistically significant differences (p < 0.05) between the CP and PR groups.
