Defining the Normal Bacterial Flora of the Oral Cavity
ABSTRACT More than 700 bacterial species or phylotypes, of which over 50% have not been cultivated, have been detected in the oral cavity. Our purposes were (i) to utilize culture-independentExpand

The human oral microbiome.
The human oral cavity contains a number of different habitats, including the teeth, gingival sulcus, tongue, cheeks, hard and soft palates, and tonsils, which are colonized by bacteria. The oralExpand

Molecular Analysis of Bacterial Species Associated with Childhood Caries
ABSTRACT Although substantial epidemiologic evidence links Streptococcusmutans to caries, the pathobiology of caries may involve more complex communities of bacterial species. Molecular methods forExpand

Phylogeny of the Pasteurellaceae as determined by comparison of 16S ribosomal ribonucleic acid sequences.
Previously, virtually complete 16S ribosomal ribonucleic acid sequences were determined for 54 strains of species in the family Pasteurellaceae. The sequences for 16 additional strains have beenExpand
