The splenic cells from p47−/− and WT mice exhibited comparable rate of infection efficiency at 24 h post-incubation that were not statistically different (CD11b+ macrophages: 10.65% versus 16.8%; Ly6+ neutrophils: 3.28% versus 9.45%, p47phox−/− versus WT, respectively, Fig. 2B.b). The gene discussed is ITGAM; the disease is infection.
