What is trichophyton rubrum how is the fungus transmitted to humans?

Trichophyton: Fungal transmission occurs through direct contact with infected persons, animals, soil or fomites. Depending on their habitat, dermatophytes are described as anthropophilic (human), zoophilic (animal) or geophilic (soil). Anthropophilic dermatophytes are the most common sources of tinea infections, but zoophilic sources should be identified (if possible) and treated to prevent human reinfection.
