چکیده
Background: Trichomonas vaginalis (T. vaginalis) is a sexually transmitted protozoan parasite and the causative agent of trichomoniasis. The genetic characterization of T. vaginalis isolates shows notable genetic variation in this parasite. In the present study, we aimed to identify the T. vaginalis genotypes based on analyzing of actin gene in women specimens referred to health centers of Ilam city, southwest Iran. Methods: A total of ۱۷۶۵ female samples were collected from gynecology clinics in the city of Ilam. DNA was extracted from positive samples and nested polymerase chain reaction (Nested PCR) was used to amplify the actin gene. Then, partial sequencing and genotyping of the actin gene was performed. A phylogenetic tree was drawn using the detected genotypes of T. vaginalis and reference sequences. Results: Twenty-one of the ۱۷۶۵ urine and vaginal samples were positive for T. vaginalis. All infected individuals were married and their age in years was between ۲۵ to ۳۴. Further, the majority of infected women had cervical lesions, patchy erythema, and white color discharge. According to sequencing analysis, the isolates were identified as genotype G (n= ۸) and genotype E (n= ۲). Conclusions: From the collected samples, we were able to distinguish at least two genotypes (G and E) of T. vaginalis. However, lesser is known about these genotypes in the city of Ilam. Further studies with a higher number of isolates should be performed in order to understand the implications of these results in this region.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.
