Diversity and morphology of members of the phylum "synergistetes" in periodontal health and disease.

ABSTRACT: Members of the phylum "Synergistetes" have frequently been detected in the human oral cavity at sites of dental disease, but they have rarely been detected in studies of oral health. Only two oral "Synergistetes" taxa are cultivable. The aims of this study were to investigate the diversity of "Synergistetes" in the oral cavity, to establish whether "Synergistetes" taxa are more strongly associated with periodontitis than with oral health, and to visualize unculturable "Synergistetes" in situ. Sixty samples (saliva, dental plaque, and mucosal swabs) were collected from five subjects with periodontitis and five periodontally healthy controls. Using phylum-specific 16S rRNA gene primers, "Synergistetes" were identified by PCR, cloning, and sequencing of 48 clones per PCR-positive sample. Subg
