Characterization of novel human oral isolates and cloned 16S rDNA sequences that fall in the family Coriobacteriaceae: description of olsenella gen. nov., reclassification of Lactobacillus uli as Olsenella uli comb. nov. and description of Olsenella profusa sp. nov.

Abstract excerpt

The diversity of organisms present in the subgingival pockets of patients with periodontitis and acute necrotizing ulcerative gingivitis (ANUG) were examined previously. The 16S rRNA genes of subgingival plaque bacteria were amplified using PCR with a universal forward primer and a spirochaete-selective reverse primer. The amplified DNA was cloned into Escherichia coli. In one subject with ANUG, 70 clones were...
