Dermatiaceous fungi are pigmented, saprophytic organisms - Phaeohyphomycetes
*They usually infect animals secondary to traumatic implantation of the organisms, and are therefore most often seen in subcuticular or cutaneous sites.
*In immunuocompromised hosts they may develop systemic infections.
Phaeohyphomycosis:
*It occurs sporadically in cats, horses, cattle, fish, reptiles, amphibians, and birds, and rarely in dogs.
Fungi implicated in animal phaeohyphomycosis include: Exophiala sp., Phialophora sp., Pseudomicrodochium sp., Bipolaris sp., Moniella sp., Cladosporium sp., Wangiella sp., Curvularia spp., Exserohilum sp., Alternaria sp., Staphylotrichum sp., and Xylohypha sp.
*Culture is necessary for definitive diagnosis.
