– Dermatophytes are very interested in keratin. Keratin is a protein that is produced by skin cells and is placed in the outer layer of the skin. Hair and nails are also made of keratin, that’s why dermatophyte fungi can infect the skin, hair and paws of animals or humans.

Also, dermatophyte fungi can cause small granular lesions on the cat’s skin, which can be felt under the hand as a result of petting. This condition is called millet skin inflammation.


– The symptoms of dermatophytic fungi can be similar to several other skin diseases, so the diagnosis should never be made based only on the appearance and symptoms of hair loss. In case of suspicion of a disease caused by a dermatophytic fungus, the veterinarian can diagnose the disease to some extent by first placing the bald area under the ultraviolet light, which is called Wood’s lamp. Usually, the lesions that some of these dermatophytes cause as a result of their activity turn light green under the Wood’s lamp. However, the absence of these night green seeds does not mean that the animal is not infected, and some dermatophytes do not produce their own color.
