| Outline of Final Research Achievements |
Both 16S rDNA and 16S rRNA sequence data was obtained from the patients with osteomyelitis of the jaw in stage II (sequestrum was formed but not exposed in the oral cavity). Furthermore, sequence data was obtained from the patients with both peri-implantitis and periodontitis. In the analysis of peri-implantitis and periodontitis, it was revealed that the community structure of core bacteria with high activity differed from that of the core microbiome determined by only 16S rDNA. Moreover, there was no correlation between relative abundance and the bacterial activity. Furthermore, despite the conspicuous difference in bacterial composition, the predicted functional profiles of the 2 diseases were quite similar. Finally, we revealed that the bacterial species forming the core connection of the co-occurrence network and its structures were quite different between the 2 diseases. These data may provide a possible explanation for the differing tractability of these diseases.
