FIG. 3.

Bactericidal capacity of CGD PMNs after IFN-γ treatment in vivo. CFU were counted after 90 min of incubation with S. aureus. The shaded area illustrates the bactericidal capacity of control PMNs (± SD); controls were not treated with IFN-γ. Pretreatment there was no killing capacity of CGD PMNs at all, leaving 159% residual bacteria, i.e., a bacterial growth. However, on day 3 a maximal killing capacity, leaving 75% residual bacteria, was noted. Error bars indicate SDs.
