Symptoms: Lesions tend to be circular, with grayish flakes present. Pruritis can be intense, or may not be present.
Diagnostics: Fungal culture, especially from hair follicles pulled from the edges of the lesions.
Special Notes: In horses this condition tends to be an acute problem and is generally easier to manage than in the small animals; however, it can be very infectious and travel through a barn rapidly on shared equipment.
Principles for Supplementation: Support for the immune system is important in these patients.
