Each donor has a mixed population of corncobs. For each of 14 donors, the imaged corncobs were divided into 5 μm segments and the presence of S. mitis/oralis/infantis, S. cristatus, other Streptococcus spp., and Porphyromonas spp. in each segment was recorded. The relative abundance of each type of corncob in each donor is shown (A). Black bars indicate the total number of 5 μm corncob segments counted in each donor (B). Corncob segments consisting of S. cristatus alone constituted 42.3% of the total and a mean of 42.7% (range 6% to 87%) across the 14 individuals. Segments consisting of pure S. mitis/oralis/infantis were 19.4% of the total, mean 23.8% (range 0 to 55%) and pure Porphyromonas sp. segments were 6.8% of the total, mean 6.1% (range 0–20%). Mixed segments and segments including unidentified Streptococcus spp. were 31.6% of the total and mean 27.4% (range 0–50%)
