This is another high-power photomicrograph of the thrombus stained to outline the Mucor organisms (arrows).
File:IPLab10Mucor7.jpg
This is an even higher-power photomicrograph of the thrombus stained to outline the Mucor organisms (arrows).
File:IPLab10Mucor6.jpg
This medium-power photomicrograph shows the thrombus stained to outline the Mucor organisms (arrows). Note again the ribbon-like morphology and the wide-angle branching.
File:IPLab10Mucor5.jpg
This is another high-power photomicrograph of the wall of the artery and the thrombus. Within the thrombus there are multiple variably-shaped clear areas that represent longitudinal sections and cross sections of the Mucor organisms (arrows).
File:IPLab10Mucor4.jpg
This is a higher-power photomicrograph of just the wall of the carotid artery. Note the ribbon-like clear structure with roughly parallel walls (non-septate hyphae) and right-angle branching (arrow). This is the Mucor organism.
File:IPLab10Mucor3.jpg
This is an even higher-power photomicrograph of the wall of the carotid artery (1) and the thrombus (2). Within the wall of the artery and in the thrombus there are multiple variably shaped clear areas (3). At this magnification and with this stain, it...

File:IPLab10Blasto10.jpg
This is a very high-power photomicrograph showing Blastomyces organisms stained with PAS. Note the budding organism (arrow) and the underlying pyogranulomatous inflammatory reaction in the background.
File:IPLab10Blasto9.jpg
This high-power photomicrograph shows Blastomyces organisms stained with PAS. Note the budding organism (arrow). Blastomyces has a characteristic presentation of budding which aids in diagnosis of the fungus.
File:IPLab10Blasto8.jpg

File:IPLab10Blasto7.jpg
This high-power photomicrograph shows an alveolus filled with numerous round bodies up to 25 mm in diameter. Some of these double-contour bodies (1) have a dense center and a clear halo. These are the Blastomyces organisms. The typical B. dermatitides ...
