Histological features of IA vary depending on the underlying host risk factor. Shown are representative H&E and GMS stains from A. fumigatus-infected lungs in CGD mice, steroid-treated mice and neutropenic mice at days 1, 3 and 5 post-infection. Magnification, 20x and 200x. Two independent experiments yielded similar results with a total of 4–6 mice per time-point.
