Chrysosporium is a genus of fungi in the family Onygenaceae. This genus is known for its keratinophilic properties, meaning it can degrade keratin, a protein found in skin, hair, and nails. Chrysosporium species are commonly found in soil and are important in the decomposition of organic matter.

Morphology

Chrysosporium species are characterized by their production of conidia, which are asexual spores. These conidia are typically single-celled, hyaline, and have a thin wall. The conidia are produced on short, simple conidiophores that arise directly from the hyphae. The colonies of Chrysosporium are usually white to cream-colored and have a powdery texture due to the abundance of conidia.

Ecology

Chrysosporium species are saprophytic fungi, meaning they obtain nutrients by decomposing dead organic matter. They are commonly found in soil, especially in areas rich in keratinous debris such as feathers, hair, and skin. Some species of Chrysosporium are also known to be thermophilic, thriving in high-temperature environments such as compost heaps.

Medical Significance

While most Chrysosporium species are not pathogenic, some have been implicated in opportunistic infections in humans and animals. These infections are rare and typically occur in immunocompromised individuals. Chrysosporium infections can manifest as skin lesions, respiratory infections, or systemic mycoses.
