Typing 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 کاملSubtyping of hepatitis C virus isolates by a line probe assay using hybridization.
A reverse hybridization test (Inno-LiPA HCV; Innogenetics, N.V., Zwijnaarde, Belgium) was used for typing hepatitis C virus. All 38 samples, typed by PCR with primers from core and NS5 genes, were also genotyped by this test. Of the samples, 33 (87%) had the same subtypes by both assays. The correlations between PCR and Inno-LiPA for individual types were 77% for type I (1a), 90% for type II (1...
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 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 ...
متن کاملUse of a commercially available line probe assay for genotyping of hepatitis C virus 5a strains.
To validate a commercially available line probe assay for samples containing the infrequently found hepatitis C virus (HCV) genotype 5a, we sequenced a 511-nucleotide fragment of the NS4b region of Belgian and South African HCV genotype 5a samples. Phylogenetic analysis of the sequence data was performed. For the 77 HCV genotype 5a samples collected, there was 100% concordance between the genot...
