BACKGROUND & OBJECTIVE Glycoprotein B (gB), involved in cell-to-cell transmission of human cytomegalovirus (HCMV), is a critical factor in tissue tropism and viral pathogenesis. The aim of the present study was to compare the efficiency of PCR-based RFLP and multiplex nested PCR for gB gene of HCMV to determine their genotype in clinical specimens from patients with HCMV. METHODS The PCR base...
BACKGROUND It is clinically important to detect and type human papillomavirus (HPV) in a sensitive and specific manner. OBJECTIVES Development of a nested-polymerase chain reaction-restriction fragment length polymorphism (nested-PCR-RFLP) assay to detect and type HPV based on the analysis of L1 gene. METHODS Analysis of published DNA sequence of mucosal HPV types to select sequences of new...
background: anaplasmosis belongs to the complex of several tick-borne diseases and can cause diseases in the livestock with high economical losses. cattle that recover from acute infection become carriers and the parasite can persist most probably for the lifetime in the blood. the aim of the present study was the determination of the persistently infected cattle in a region of iran with the pr...
تعیین گونه های عامل لیشمانیوز پوستی به روش مولکولی pcr-nested و rflpدرشهرستان جهرم. لیشمانیوز یکی از بیماریهای انگلی می باشد که توسط تک باخته ای از جنس لیشمانیا ایجاد می شود. این بیماری به صورت گسترده در مناطق مختلفی از جهان مشاهده می شود . بیماری دارای طیف وسیعی بوده که در یک طرف آن زخمی ساده است و در طرف دیگر طیف اشکال پوستی ، پوستی مخاطی ، و لیشمانیوز احشایی می باشد که حتی می تواند منجر به ...
Objective: The objective of this study was to investigate the group/subgroup phytoplasma agent in peppers showing symptoms. Material and Methods: In study, plants collected from Iğdır province 2020 were analyzed using direct nested PCR tests, BLASTn, iphyClassifier, Mega 7, pDRAW32 programs used. Results: tests performed, approximately 1.2 kb DNA fragments specific obtained. 16S rRNA nucleotide...
In order to detect several new HLA-A class I alleles that have been described since 1998, the original PCR-RFLP method developed to identify the 78 alleles recognized at that time at high resolution level was adapted by us for low and medium resolution levels using a nested PCR-RFLP approach. The results obtained from blood samples of 23 subjects using both the PCR-RFLP method and a commercial ...
هدف: gb ویروس c جزء ویروسهای منتقل شونده از راه خون، فرآوردههای خونی و از طریق جنسی است و از آنجا که راه انتقال آن با ویروسهای عامل هپاتیت مشترک است، طی این مطالعه ویروس را در بین افراد hbsag مثبت با روش حساستر semi nested-pcr جداسازی کرده و ژنوتیپهای ویروس با روش rflp تعیین شد. مواد و روشها: در تحقیقی که بهصورت مقطعی بین سالهای 1389 تا 1390، روی 100 نمونه سرمی افراد hbsag مثبت انجام ش...
Cryptosporidium parvum and C. hominis have been the cause of large and serious outbreaks of waterborne cryptosporidiosis. A specific and sensitive recovery-detection method is required for control of this pathogen in drinking water. In the present study, nested PCR-restriction fragment length polymorphism (RFLP), which targets the divergent Cpgp40/15 gene, was developed. This nested PCR detecte...
objective: gbv-c is a virus transmissible via blood transfusion and sexual routes. because of the shared transmission routes in gbv-c and hepatitis b virus (hbv) we have attempted to detect gbv-c in hbsag-positive patients using the more sensitive semi-nested pcr. we used restriction fragment length polymorphism (rflp) to determine genotype. methods: a total of 100 serum samples were collected...
background: the aim of this study was to detect and characterize cryptosporidium spp. in water samples collected from recreational ponds of chaharmahal va bakhtiyari province of iran . methods: thirty water samples were collected from november 2009 to may 2010. each sample contained 10 liters of water. we used the ssu rrna-based pcr-rflp technique. results: out of thirty samples examined, 6...
