Onygenaceae
Onygenaceae[edit | edit source]
The Onygenaceae is a family of fungi within the order Onygenales. This family is notable for its members that are often associated with keratin-rich environments, such as animal hair, skin, and feathers. The Onygenaceae family includes several genera that are of medical and veterinary importance due to their ability to cause infections in humans and animals.
Characteristics[edit | edit source]
Members of the Onygenaceae family are typically characterized by their ability to degrade keratin, a tough protein found in skin, hair, and nails. This ability makes them well-suited to colonize and decompose keratinous materials. The fungi in this family are usually found in soil, particularly in areas rich in animal remains or waste.
The spores of Onygenaceae fungi are often small and can be easily dispersed by air or contact. These spores can infect hosts by penetrating the skin or being inhaled, leading to various infections.
Medical Importance[edit | edit source]
Some species within the Onygenaceae family are known to cause dermatophytosis, commonly referred to as ringworm, in humans and animals. These infections are typically superficial, affecting the skin, hair, and nails. However, certain species can cause more severe infections, particularly in immunocompromised individuals.
The genus Trichophyton, for example, includes species that are common causes of athlete's foot, jock itch, and other skin infections. Another genus, Microsporum, is also known for causing similar infections.
Ecology[edit | edit source]
Onygenaceae fungi are saprophytic, meaning they feed on dead or decaying organic matter. They play a crucial role in the ecosystem by breaking down keratinous materials, thus recycling nutrients back into the environment.
These fungi are commonly found in soil, especially in areas where there is an abundance of animal remains or waste. They can also be found in bird nests, where they decompose feathers and other keratin-rich materials.
Genera[edit | edit source]
The Onygenaceae family includes several genera, some of which are:
Each of these genera contains species that are adapted to specific ecological niches and have varying degrees of pathogenicity.
