FIG. 6.

The effect of lectin site inhibition of opsonophagocytosis of GBS serotypes Ia, II, III, and V by NADG (50 mM) (solid bars), fructose (50 mM) (stippled bars), or OKM1 (10 μg/ml) (open bars). The mean (± SEM) inhibition mediated by NADG was significantly greater for serotypes Ia, III, or V than for serotype II (P ≤ 0.02 for each serotype versus type II GBS). Similarly, the mean (± SEM) inhibition mediated by OKM1 was significantly greater for serotypes Ia, III, or V GBS than for type II GBS (P < 0.03).
