چکیده
Atypical Mycobacterium granulomatous skin infections are often accured by Mycobacterium marinum, M. ulcerans, M. fortuitum, and M. avium colonies. Skin infections probably originate from an environmental source such as contacting with aquatic animals, fish farming and swimming in the pools, and inoculate into skin through skin wounds, scratches, trauma, and surgery. The lesions appear as purple papules, nodules in hands and feet, plaque blisters wart ulcers and markers transmission (sporotrichosis) in the path of lymph nodes. They have granulomatous accumulation with giant cells, and abscess pus appears, and sometimes in the form of ulcerative. Infection is limited to the skin, while in immunosuppressed cases it would be able to infect the whole body. To determine if Mycobacteria were present in granulomatose skin lesion, a total of ۵۸ paraffine embedded tissue blocks were obtained and their DNA was extracted. The polymerase chain reaction (PCR) was used to amplify the HSP-۶۵ gene. PCR amplification demonstrated the presence of Mycobacterium spp. In ۱۸ blocks (۳۱%). Among these ۱۸ blocks, ۸ (۴۴%) were positive for M. marinum, ۳ (۱۷%) for M. ulcerans, ۵ (۲۷%) for M. fortuitum and M. chelonae, and ۲ (۱۲%) for M. avium. We conclude that Mycobacteria ought to be considered in the treatment of skin granulomas in Iran.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.
