61 By using a novel real time genotyping and quantitative PCR (GQ-PCR) assay, we compared with 62 direct sequence analysis, reverse hybridization, and the multiplex PCR by detecting 127 HBV 63 infected patients. We found that GQ-PCR had the highest concordance with sequence analysis and 64 the highest detection rate for mixed genotype detecting. 65

To date the true prevalence of hepatitis C virus (HCV) mixed-genotype infections has not been established mainly because currently available methods are not suitable for the detection of mixed genotypes in a viral population. A novel semiautomated genotyping method, primer-specific and mispair extension analysis (S-PSMEA), which is more reliable than other genotyping assays was developed for de...

Among numerous available genotyping techniques, mass spectrometry (MS) based methods play a major role in providing high quality genotype data at reasonable costs for research and diagnostics, e.g. for pharmacogenetic applications. Ion-pair reversed-phase liquid chromatography hyphenated to electrospray ionization time-of-flight MS (ICEMS) is, for example, a powerful instrument that allows a di...

Purpose: Human adenoviruses are a major cause of epidemic keratoconjunctivitis. Of over 60 genotypes, subgroup D is associated with There are, however, no data regarding the genotypes conjunctivitis-causing in Korea. The purpose this study was to determine types causing keratoconjunctivitis and clinical manifestations Korea.Methods: From November 2016 September 2017, 20 conjunctival swab specim...

Genotyping of hepatitis C virus (HCV) plays an important role in the treatment of HCV. As new genotype-specific treatment options become available, it has become increasingly important to have accurate HCV genotype and subtype information to ensure that the most appropriate treatment regimen is selected. Most current genotyping methods are unable to detect mixed genotypes from two or more HCV i...

PURPOSE Functional polymorphisms of the UGT1A1 gene, particularly the UGT1A1*28 variant, are associated with the severity of the bone marrow suppression in patients with metastatic colorectal cancer receiving irinotecan. This study assesses the cost-effectiveness of screening for UGT1A1*28 polymorphism associated with primary prophylactic Granulocytes Colony Stimulating Factor in patients homoz...

AIMS Persistent infection indicated by detection of human papillomavirus 16 (HPV-16) on repeat testing over a period of time poses the greatest cervical cancer risk. However, variants of HPV-16, HPV-31 and HPV-33 may share several short sequence homologies in the hypervariable L1 gene commonly targeted for HPV genotyping. The purpose of this study was to introduce a robust laboratory procedure ...

multilocus variable number tandem repeat (vntr) analysis (mlva) is a new typing method with several advantages compared to other methods. dissemination of shigella is highly significant in developing countries. whilst shigella is becoming increasingly important as an etiologic agent of pediatric shigellosis in iran, little is known about the genetic diversity of the local strains. therefore, th...
