Background

Dermatophytes represent the most numerous and widespread group of all mycoses and have the capacity to invade keratinized tissue of humans and animals to facilitate infections that are generally restricted to the corneocytes of the skin, hair and nails.
Dermatophytes are classified in three genera: Epidermophyton, Microsporum and Trichophyton. Diagnosis of these infections is currently based on microscopy or histology associated with culture on specific agar media. However, direct microscopy lacks specificity and culturing has a long turn-around-time of 2-4 weeks and is prone to contamination. These limitations can be prevented by the use of molecular diagnostics.
