- Fungal organism with thin-walled, septate, branching hyphae; sized 2.5-5 microns.
- P. boydii is the sexual form of Scedosporium apiospermum.
- Ubiquitous; typically found in soil, sewage, brackish/polluted water.
- Identificaiton through fungal culture is imperative as histopathology is indistinguishable from Aspergillus.
- Acquisition through inhalation or traumatic inoculation through the skin.
- High concentrations of Scedosporium species can be found near gas stations, in urban parks, at industrial sites, and within agricultural areas (this is related to nitrogen concentration and pH).
