difference between dermatophyte and non-dermatophyte
Dermatophyte infections
These infections are caused by a group of fungi that can invade the skin, hair, and nails. Symptoms include rashes, scaling, and itching. Dermatophytes are the most common cause of nail infections, accounting for about 90% of cases. The most common dermatophyte is Trichophyton rubrum. Dermatophyte infections are usually treated with topical or oral preparations.
Non-dermatophyte infections
These infections are caused by fungi that are found in soil, decaying plant debris, or plant disease. Non-dermatophyte infections can also affect the skin and nails, but they are more common in patients with other diseases that affect the nails, in the elderly, and in immunocompromised patients. Non-dermatophyte infections require specific diagnostic criteria to differentiate them from contamination. One recommended treatment for non-dermatophyte nail infections is oral itraconazole
