FIG. 2.

Effect of preincubation of M. fermentans on binding to HeLa cells. Binding was performed as described in Materials and Methods by using microorganisms preincubated for 1 h at 37°C (open bars) in adherence reaction mixtures containing various concentrations of NaCl. Solid bars, control without preincubation. The data are means ± standards deviations of three to five independent experiments.
