IL2 and infection: We collectively refer to these three classes of phenotypes as “quantitative infection phenotypes.” We identified a significant association between the ST93 A/B clade and the in vitro macrophage uptake rate and patient CSF interleukin-2 (IL-2) level (Fig. 4C) (nonparametric Wilcoxon rank sum test; uptake W = 226, P = 0.011; IL-2 W = 66.5, P = 0.022).
