Epidermophyton is a genus of fungi that primarily causes skin infections in humans. It is known for leading to conditions such as athlete's foot and ringworm. These fungi thrive in warm, moist environments and can be transmitted through direct contact with infected individuals or contaminated surfaces. The most common species within this genus is Epidermophyton floccosum, which primarily affects the skin and nails. Infections are typically treated with antifungal medications, and maintaining good hygiene can help prevent their spread.
