Description:Magnified 562X, this photomicrograph of a human lung tissue specimen, which had been stained using fluorescein-labeled A. boydii antiglobulin, revealed the presence of the fungus Pseudallescheria boydii, formerly known as Allescheria boydii.
A pathogenic fungus, P. boydii, which is actually the teleomorph, or sexual reproductive stage of the fungus Scedosporium apiospermum, which is the asexual form, has been linked as a cause for the disease in humans known as mycetoma, which is a chronic infection that is progressively inflammatory, and usually involves the subcutaneous tissues, but can become systemically disseminated. Mycetoma occurs after the environmentally-derived pathogen has been introduced into a traumatically-induced wound.
