Porphyromonas gingivalis in saliva associates with chronic and aggressive periodontitis.

ABSTRACT: Objective: To characterize the salivary microbiota of patients with aggressive periodontitis, patients with chronica periodontitis and orally healthy individuals. Methods: A total of 81 unstimulated saliva samples from aggressive periodontitis patients (n = 31), chronic periodontitis patients (n = 25), and orally healthy controls (n = 25) were examined. The V1-V3 region of the 16S rDNA gene was sequenced with Illumina® MiSeqTM, and sequences were annotated to the expanded Human Oral Microbiome Database (eHOMD). Results: A mean percentage of 97.6 (range: 89.8-99.7) of sequences could be identified at species level. Seven bacterial species, including Porphyromonas gingivalis, were identified with significantly higher relative abundance in saliva from aggressive periodontitis patients than in
