Examples of spores present in granulomata. Section of weasel lung showing a granuloma surrounding a central spore with a PAS positive cell wall (arrow); in this example the spore appears to be devoid of content. The spore is surrounded by a loose aggregation of macrophages and an outer layer of mostly lymphocytes and fibroblasts. Per-iodic Schiff stain, bar = 50 μm. Inset: High magnification view of a spore within a granuloma of a stoat showing the double-wall and the inner body. H & E stain, bar = 25 μm
