چکیده

Background and Aim : Bacteriophages (phages) are bacterial intracellular parasites. They are the most abundant organisms in the world and are present in any environment that contains bacteria, including sewage. Lysogenic phages, unlike lytic phages, do not begin to multiply immediately after entering the host and may integrate their genome into a bacterial gene called a prophage. Prophages can have a wide range of phenotypic effects on host bacteria. They can also regulate bacterial populations by altering bacterial gene expression. Enterococcus are gram-positive bacteria whose species cause infections in humans. Recently, Enterococcus has become resistant to a variety of antimicrobials, so that today we see high resistance of Enterococcus to a variety of antibiotics, including vancomycin.Methods : In this study, Enterococcus faecium EntfacMY was isolated from biological samples and its genome was examined.Results : After analyzing the genome of these bacteria, ۲۵۴ prophage genes were identified. The prophage included ۳۹ housekeeping genes, ۴۱ genes related to replication and regulation, ۸۰ genes in the group of structural and packaging genes and ۴۸ genes in the group of lysis. ۴۶ genes with unknown function were also identified.Conclusion : As a result, identification and analysis of prophage genomes can be effective in better understanding their role in the development of bacterial resistance to antibiotics. Identifying and studying prophages can also help develop genetic engineering tools and therapeutic use of bacteriophages. The identified genes were annotated in the DNA Data Bank of Japan.

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.
