|Description:||Under a magnification of 475X, this teased wet mount-prepared specimen revealed some of the ultrastructural details exhibited by two coremia from the saprophytic fugal organism, Pseudallescheria boydii, which is also known as Petriellidium boydii, and Allescheria boydii. The coremia represent the fruiting bodies of some fungal organisms, and consist of a loosely-bound bundle of conidiophores arranged in a manner analogous to stalks of wheat, and giving rise to the conidia, or spores, at their distal tips.|
Pseudallescheria boydii is a true fungal organism, known to be a cause of the disease known as mycetoma, a cutaneous infection, though this organism has also been cultured from infections involving the lungs, cornea, ear, sinuses, and meninges. Immunocompromised individuals are at a greater risk for succumbing to pathologic involvement with this organism. In the case of this particular patient, it was present in this section of heart tissue.
