Total number of anaerobic bacterial colony counts, total number of Veillonella species counts and the number of isolates from each subject identified using species-specific primer sets. CFU: colony-forming unit; detection limit <0.1% of the total count. Individual species as a percentage of the number of isolates from each subject identified using species-specific primer sets.
