PAS stain. An example of Aspergillus fumigatus.
(PAS-stained) in a patient with chronic granulomatous disease showing a 45 degree branching hypha within a giant cell. Rather bulbous hyphal ends are also seem, which is sometimes found inAspergillus spp. infections, histologically. (x800)

Notes:
Comparison of GMS and PAS stains. Patient with disseminated Trichosporon spp. infection. Both x60. In the GMS image, substantial background staining of elastin is seen, with more prominent yeasts superimposed. In contrast, the PAS stain shows the tissue morphology, with bright pink yeasts also visible.

Aspergillosis in penguins. Lesions found in fatal cases of captive Magellanic penguins (Spheniscus magellanicus) with aspergillosis. Air sacs thickened with abundant plaque-like caseous and necrotic debris covering the wall with greyish-green fungal colonies on the internal surface.
