The Aspergillicidal capacity of CGD PMN after IFN-γ treatment. Values are expressed as residual % of Aspergillus hyphae compared with wells without PMN added ±SD. Controls are indicated as shaded area ±SD. In the text the effect of the IFN-γ is described as increase in % killing capacity. This is calculated as the percentage of pretreatment residual % hyphae − residual % for each separate day.
