Coccidioides immitis G. W. Stiles 1896

This photomicrograph revealed some of the histopathologic characteristics found within a pus specimen, which was prepared using periodic acid-Schiff (PAS), and which had been harvested from a skin lesion in a case of cutaneous coccidioidomycosis. In this particular specimen you’ll note the chlamydospore, or immature spherule of a Coccidioides immitis fungal organism. As the reproductive structure of this, as well as other types of fungi, this spherule is also known as a chlamydoconidium, and contains the organism’s endospores.Created: 1975

This photomicrograph revealed some of the histopathologic characteristics found within a pus specimen, which was prepared using potassium hudroxide (KOH), and which had been harvested from a skin lesion in a case of cutaneous coccidioidomycosis.
