Abstract: This study was carried out with the purpose of determining the genus and species of regional dermatophytes and its importance in providing the ways for preventing these diseases. The study was established as census during a one year period (from 2007 through 2008). Questionnaires were completed for recording necessary information by 294 patients suspected of dermatophytosis and then samples from skin, nail and hair were obtained. All of the specimens were assessed by two methods, direct and culture. The obtained results were analyzed by SPSS 15 software. One hundred and seventy two patients showed different kinds of dermatophytosis. The age average was 23.5 years and the number of affected men was more than that of women. Only Tinea manuum in women was more than in men. Most kinds of dermatophytosis were Tinea corporis (25.6%) and Tinea cruris (25%). Epidermophyton flocosum and trichophyton verrocosum were the most common dermatophytes of the region. Control and prevention of these diseases and also preclusion of the economic losses in regional husbandry industry will be fulfilled. Moreover, definitive diagnosis of dermatophytosis before initiating the therapy and public education concerning this disease can be very effective in reducing the infection rates.
