Dermatophytes are filamentous, hyaline, septate, fungi that have tropism by keratinized structures, causing infections in the skin, hair and nails, called dermatophytosis. These diseases are manifested as chronic lesions and are difficult to treat. The WHO estimates that 25% of the world population is affected by dermatophytes. Molecular diagnosismethods based on detection of fungal DNA have been developed with the advantage of being faster, more sensitive and specific. The early and assertive diagnosis of dermatophytosis should prevent unnecessary treatments. This study proposes to test a method for molecular diagnosis with low cost and easier than regular exams. This method is based on two PCR reactions, which will allow identification of the species belonging to the three genera Epidermophyton, Trichopyton and Microsporum. Sixty-seven suspected samples with from mycologylaboratory at the Lauro de Souza Lima Institute were tested. The extraction method tested showed good yield and low purity. Modifications were tested in order to improve DNA purity, however, the 260/280nm ratio could not be improved, which possibly prevented the function in go the PCRs. Changes in the method of collecting patient material have the potential to improve these
