a
Mean and standard deviation values were derived from triplicate experiments.
b
Significantly different from the wild type (P < 0.05) as calculated by one-way analysis of variance, followed by the Student-Newman-Keuls test.
c
-, The number of adhering cells was too low for accurate analysis (<0.15 × 106/cm2).
