Phagocytosis score (mean value sumarized in C) for the treatments across the emm types. For all emm types, MOP 50 was used in the experiments, except for emm 179 (MOP 25) and emm 4 (MOP 100). Statistical comparison was done by comparing all treatments to Ab25 IgGh 47 with one-way ANOVA with multiple comparisons and post hoc Dunnett’s test to correct for multiple comparisons. **** denotes P -value < 0.0001, *** denotes P -value < 0.001, ** denotes P -value < 0.01 * denotes P < 0.05 and P -value > 0.05 is ns. The mean is shown and the error bars are SEM throughout the figure. In D – F , for emm 4 and emm 179, N = 4 independent experiments were performed, while for emm 12, 28, 79, and 81, N = 5 independent experiments were performed.
