چکیده
Tuberculosis (TB) is one of the most important AIDS associated infectious diseases worldwide. It is a leading cause of illness and death among people with HIV/AIDS in resource-poor areas of the world. The annual incidence of TB among indigenous Iranians stands at ۱۴ cases per ۱۰۰,۰۰۰ inhabitants. This study aimed to identify Mycobacterium infection among Iranian HIV positive patients. Two sputum specimens were collected from smear positive AIDS patients. Samples were cultured on Lowenstein-Jensen media for three weeks. DNA was extracted from two samples based on van Embden protocol. To identify Mycobacterium tuberculosis complex, a PCR was conducted to amplify a ۲۴۵ bp fragment of IS۶۱۱۰ element, followed by RD۱۲ method to confirm PCR result. Whole DNA-RFLP with PvuII restriction enzyme was employed to genotype the cultured isolates. The results obtained by colonial morphology, PCR, and RD۱۲ methods showed that both isolates were belonging to M. tuberculosis, and Genotyping of the isolates by RFLP technique displayed that two isolates were belonging to different strains of M. tuberculosis.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.
