FIG. 2.
Adhesion of L. monocytogenes to macrophages following treatment of the organism with increasing concentrations of the carbohydrate-oxidizing compound sodium metaperiodate at pH 5.0. Binding data were generated by IFA. Controls were untreated L. monocytogenes (column 1) and L. monocytogenes in acetate buffer at pH 5.0 buffer (column 2). Bars represent standard deviation of the mean. Statistical significance at all concentrations: P < 0.0001.
