Mean log-transformed numbers of A.actinomycetemcomitans 16s rDNA and cdtB in shallow, moderate and deep periodontal pockets. a. Mean log-transformed numbers of A.actinomycetemcomitans 16 s rDNA in shallow (n = 48), moderate (n = 20), deep (n = 11) periodontal pockets from CP subjects were 1.9 ± 0.8, 2.1 ± 0.8 and 2.5 ± 1.0, respective. Mean log-transformed numbers of A.actinomycetemcomitans 16 s rDNA in shallow (n = 52), moderate (n = 29), deep (n = 24) periodontal pockets from AgP subjects were 1.7 ± 0.8, 2.3 ± 0.8 and 3.4 ± 1.1, respective. * The quantity of A.actinomycetemcomitans in deep periodontal pockets from AgP was higher than CP (P < 0.05). b. Mean log-transformed numbers of A.actinomycetemcomitans cdtB in shallow (n = 48), moderate (n = 20), deep (n = 11) periodontal pockets from CP subjects were 0.8 ± 0.1, 1.5 ± 0.8 and 1.3 ± 0.7, respective. Mean log-transformed numbers of A.actinomycetemcomitans 16 s rDNA in shallow (n = 52), moderate (n = 29), deep (n = 24) periodontal pockets from AgP subjects were 0.8 ± 0.1, 1.6 ± 0.8 and 2.6 ± 1.0, respective. * The quantity of A.actinomycetemcomitans cdtB in deep periodontal pockets from AgP was higher than CP (P < 0.05).
