a
The experiments were carried out with staphylococci exposed to 1% BSA prior to the experiments.
b
The average standard deviations (n = 4) were as follows: for the initial deposition rate, ±110 cm−2 s−1; for the number of cells adhering after 4 h, ±0.5 × 106 cm−2; for β0, ±124 × 10−3 s−1; for β∞, ±0.3 × 10−3 s−1; and for 1/δ, ±0.3 s.
