Genotyping hepatitis C viruses from Southeast Asia by a novel line probe assay that simultaneously detects core and 5' untranslated regions.
Hepatitis C viruses (HCVs) display a high level of sequence diversity and are currently divided into six genotypes. A line probe assay (LiPA), which targets the 5' untranslated region (5'UTR) of the HCV genome, is widely used for genotyping. However, this assay cannot distinguish many genotype 6 subtypes from genotype 1 due to high sequence similarity in the 5'UTR. We investigated the accuracy ...
متن کاملSecond-generation line probe assay for hepatitis C virus genotyping.
Because of the enormous variability of hepatitis C virus (HCV), the development of reliable genotyping assays is a formidable challenge. The optimal genotyping region appears to be the 5' untranslated region (UR) because of high conservation within, but considerable variability between, genotypes. In this study, 21 probes dispersed over seven variable 5' UR areas were applied to a line probe as...
متن کاملTyping of hepatitis C virus isolates and characterization of new subtypes using a line probe assay.
A reverse-hybridization assay, the line probe assay (LiPA), based on variations found in the 5' untranslated regions of the different hepatitis C virus (HCV) genotypes was developed, permitting simple and fast determination of four HCV genotypes and their subtypes. Using this assay, 61 PCR-positive Brazilian HCV sera were typed. Of the sera, 33% had a type 1 HCV infection, 38% had type 1b (rela...
متن کاملEvaluation of Versant hepatitis C virus genotype assay (LiPA) 2.0.
Hepatitis C virus (HCV) genotyping is a tool used to optimize antiviral treatment regimens. The newly developed Versant HCV genotype assay (LiPA) 2.0 uses sequence information from both the 5' untranslated region and the core region, allowing distinction between HCV genotype 1 and subtypes c to l of genotype 6 and between subtypes a and b of genotype 1. HCV-positive samples were genotyped manua...
متن کاملdevelopment and application of an in-house line probe assay for hepatitis c virus genotyping
background hepatitis c virus (hcv) is the major cause of chronic liver disease. hcv is a single stranded positive sense rna of approximately 9.6 kb. because of high conservativeness of 5΄untranslated region of hcv genome, it is widely used for virus genotyping. different methods are used for the virus genotyping, but all involve some difficulties. objectives the aim of the present study was to ...
