  • a Shown is the percentage of aggregating cells, measured by decrease in OD700, of the total number of added bacteria. Also shown is the percentage of adhering cells of the total number of added bacteria. Values in parentheses represent the adherence (percentage) of bacteria to hydroxyapatite beads coated with a larger amount (12 μg/ml) of gp340.
