Quick Summary

Dermatophytes are a group of fungi that infect the skin, hair, and nails of humans and animals. The genus Trichophyton is one of the primary causes of these infections, commonly leading to conditions such as athlete's foot, jock itch, and ringworm. These fungi are found worldwide, with certain species being more prevalent in specific regions.123

Dermatophytes thrive by feeding on keratin, a protein found in skin, hair, and nails. They form colonies composed of thread-like filaments called hyphae. Treatment for dermatophyte infections typically involves antifungal drugs, which work by either damaging the fungal cell membrane or inhibiting the synthesis of essential components like ergosterol.314
