Interesting stuff I found:
-A few dermatophyte species are soil inhabitants (geophilic), eg, M gypseum and T terrestre, and cause disease in animals that are exposed while digging or rooting.
-….the housefly, Musca domestica, can transmit M canis mechanically with its outer body surface for as long as 5 days
-Broken hairs infected with spores are important sources for spread of the disease.

-feet are a reservoir of fungus and ringworm can easily make its way into the home on your shoes.
