Exposure to DE enhances influenza induced pulmonary inflammation. BAL was obtained day 1, 4, 8, and 14 p.i. A) Neutrophil counts per ml of BAL. B) Protein concentration (μg/ml) in BAL. C) Pathology scores of mouse lung sections were stained with H & E and visualized and scored using light microscopy in tissues collected on day 4 p.i. Left column is representative of 100× magnification and right column is representative of 400× magnification. *significantly different from air exposed mice (p < 0.05, n = 8 for uninfected; n = 11 for influenza infected).
