Scopulariopsis spp

Scopulariopsis is a filamentous fungus that inhabits soil, plant material, feathers, and insects. It can be found worldwide. Several species of Scopulariopsis have teleomorphs, the sexual reproductive stage typically known as a fruting body, which are classified in the genus Microascus. While Scopulariopsis is often considered to be a contaminant, it may cause infections in humans, particularly in immunocompromised patients. It is resistant to the benomyl fungicide.Scopulariopsis spp. colonies can grow moderately or rapidly. They can mature within 5 days. They are usually granular to powdery in texture. From a frontal view they appear white in color initially and becomes light brown to a darker tan with time. There has been known to be some species that form darker colored colonies.

scopulariopsisScopulariopsis spp. has been known to cause various types of infections in humans. It is one of the fungi that can cause onychomycosis. It is especially common on the toe nails. Other health problems that Scopulariopsis is known to cause are mycetoma, skin lesions, invasive sinusitis, endophthalmitis, keratitis, endocarditis, pulmonary infections, brain abscess, and disseminated infections. Infections are normally seen mainly in immunocompromised hosts. These infections have a high risk of being mortal.
An interesting feature of a species of Scopulariopsis (brevicaulis) is its association with human deaths by producing arsine gas from arsenate dyes found in wallpapers. Arsenic is a minor constituent of soil. Arsenic is found in pesticides as well. Arsine is the most toxic form of arsenic. At certain concentrations it gives off a garlic-like odor.
