چکیده
Background: Dermatophytes are the most common fungal agents causing superficial skin infections in worldwide. Species identification of these fungi is important for therapeutic and epidemiological apects. The purpose of this study was to determine the epidemiology of dermatophytosis in patients referring to medical mycology laboratory of Razi hospital in Tehran, during ۲۰۱۴. Materials and Methods: In this study, ۶۱۰ clinical specimens were collected from patients with suspected dermatophytosis. Direct microscopy and culture examinations were performed for all samples. DNA was extracted from fungal colony using phenol chloroform. Then ITS۱-۵.۸s-ITS۲ region of ribosomal DNA (rDNA) was amplified by the universal fungal primers ITS۱ and ITS۴ and digested with enzymes mva۱. Results: In the present study, ۲۳۶ subjects (۳۸.۶%) were positive for dermatophytosis. Of these, ۶۴.۸% were male and ۳۵.۲% female. The most frequent dermatophytes isolated were Trichophyton interdigitale (۴۰.۳%), Trichophyton rubrum (۲۲.۹%) and Trichophyton tonsurans (۱۸.۷%) respectivly. Also ۵۸ samples were improperly diagnosed by morphological method, they were re-identified as Trichophyton interdigitale and Trichophyton rubrum by using PCR-RFLP. Conclusion: The survey showed that PCR-RFLP is a rapid and reliable method for discrimination of dermatophytes. We suggest using of PCR-RFLP as a valuable method along with morphological examination for diagnostic dermatophytes particularly in clinical and epidemiological settings.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
