Immunocompetent (IC) or FK506-treated (5 mg/kg/day) C57BL/6 WT mice were infected with AF CEA10 (1 × 107 conidia/mouse) i.n. C, D Flow cytometry analysis of the CD45+leucocyte populations in BAL. Representative dot plots for CD45+ cells (C) and percentages of Ly-6G-positive neutrophils infiltrating the infected lungs over a 48-h p.i. time course (D). The bars indicate the mean percentage (± SEM) of neutrophils of total CD45+ leucocytes (n = 5 mice per group). Neutrophil influx was significantly impaired in immunosuppressed mice at 6 h p.i.
