Results Figure 1 summarizes the mean levels ( 10 5 SEM) of the 40 individual test species in 1971 subgingival plaque samples from GAgP, GCP and PH subjects. All of the species tested were detected in subjects from the three clinical groups. Actinomyces naeslundii 1, A. viscosus, Corynebacterium matruchotii, Peptostreptococcus micros and Veillonella parvula were the species that presented the highest mean levels in all three clinical groups. PH subjects harboured higher mean levels of only A. naeslundii 1 and Streptococcus intermedius than subjects in either periodontitis group. GAgP subjects harboured higher mean levels of A. israelii, Campylobacter showae, Neisseria mucosa, P. endodontalis, Propionibacterium acnes, both Selenomonas spp. and all Streptococcus spp. tested except S. sanguinis and S. oralis, than GCP subjects. However, the levels of most of the microbial species tested in both periodontitis groups, tended to be very similar. A. actinomycetemcomitans was among the species detected in the lowest levels in all clinical groups (GAgP 5 0.5 0.2 10 5 ; GCP 5 1.2 0.4 10 5 ; PH 5 0.3 0.1 10 5 ). The differences between the three clinical groups and between GAgP and healthy subjects, were only statistically significant for P. gingivalis (GAgP 5 5.6 1.4 10 5 ; GCP 5 9 1.8 10 5 ; PH5 1.6 0.8 10 5 ; po0.001 and po0.05, respectively), P. nigrescens (GAgP 5 2.3 0.4 10 5 ; GCP 5 2.5 0.4 10 5 ; PH5 0.9 0.4 10 5 ; po0.05) and T. forsythia (GAgP 5 5 2 10 5 ; GCP 5 5.6 1.5 10 5 ; PH5 0.6 0.4 10 5 ; po0.001 and po0.01, r 2006 The Authors.

Comparing GCP and healthy subjects, the mean levels of P. gingivalis (po0.001), P. nigrescens (po0.05), T. forsythia (po0.001) and Treponema denticola (GCP 5 3 0.5 10 5 ; PH5 0.8 0.3 10 5 ; po0.05) were also significantly different. The differences between GAgP and GCP subjects were not statistically significant for any of the species tested. The mean proportion ( SEM) of individual species in each clinical group is summarized in Fig. 2. Samples from PH subjects harboured larger proportions of 11 of the 40 test species, including A. georgiae, A. naeslundii 1, Capnocytophaga ochracea, N. mucosa, P. acnes and S. intermedius, than those from either periodontitis group. The proportion of a number of putative and recognized periodontal pathogens, on the other hand, was higher in both GAgP and GCP subjects than in healthy individuals. Such species included C. rectus, Eikenella corrodens, Fusobacterium nucleatum, F. periodonticum, P. micros, P. gingivalis, P. melaninogenica, P. nigrescens, T. forsythia and T. denticola. It was notable, that A. actinomycetemcomitans was among the species that represented the lowest proportion in samples from both GAgP and PH subjects (0.5 0.1% and 0.7 0.3%, respectively). F. periodonticum, P. gingivalis and P. intermedia, were among the species that represented r 2006 The Authors.

The differences between the three clinical groups, as well as between GCP and healthy subjects, were statistically significant for P. gingivalis (GAgP 5 7.7 1.7%; GCP 5 9.9 1.4%; PH 5 2.3 1.4%; po0.01 and po0.001, respectively) and T. forsythia (GAgP 5 5.9 1.4%; GCP 5 5 0.9%; PH 5 0.9 0.6%; po0.01 and po0.01, respectively).
