Hepatitis C virus (HCV) intergenotypic recombinant forms have been reported for various HCV genotypes/subtypes in several countries worldwide. In a recent study, four patients living in Austria had been identified to be possibly infected with a recombinant HCV strain. To clarify results and determine the point of recombination, full-genome next-generation sequencing using the Illumina MiSeq v2 ...
Prevention programs for intravenous drug users have proven their efficacy in decreasing human immunodeficiency virus transmission but have limited effect on hepatitis C virus (HCV) contamination. A study was conducted to document the presence of HCV genome (HCV RNA) in 620 items of used injecting paraphernalia collected from representative sites. Using sensitive molecular techniques, HCV RNA wa...
To define the best marker for the follow-up and evaluation of HCV infections we determined anti-HCV antibodies, serum transaminases and HCV RNA in patients diagnosed with chronic hepatitis for C virus and treated with alpha-interferon. The presence/absence of HCV RNA was determined in serum, peripheral blood mononuclear cells (PBMC) and lymphocyte subpopulations. Samples were submitted to RT-PC...
Occult infection with hepatitis C virus (HCV) is defined as the presence of the HCV genome in either liver tissue or peripheral blood monocytes, despite constant negative results from tests for HCV RNA in serum. We investigated whether patients who maintained a sustained virologic response 12 weeks after therapy (SVR12) with direct-acting antiviral (DAA) agents for recurrent HCV infection after...
Multiple genotype 1a clones have been reported, including the very first hepatitis C virus (HCV) clone called H77. The replication ability of some of these clones has been confirmed in vitro and in vivo, although this ability is somehow compromised. We now report a newly isolated genotype 1a clone, designated HCV-RMT, which has the ability to replicate efficiently in patients, chimeric mice wit...
Consistent with other members of the family Flaviviridae, hepatitis C virus (HCV) demonstrates a high degree of sequence variation throughout the coding regions of its genome. However, there is a high degree of sequence conservation found within the 5' untranslated region (UTR) of the genome, making this region a target of choice for most nucleic acid amplification-based detection assays. In th...
results the highest prevalent genotype was genotype 4a, which was found in 57 patients (92%) followed by 2 isolates (3%) with genotype 4o, 2 strains (3%) with genotype 1g and one isolate (2%) with genotype 4n. conclusions this molecular epidemiology study revealed high prevalence of hcv genotype 4, subtype 4a among egyptian patients residing in sharkia governorate, egypt. patients and methods t...
In patients with chronic hepatitis C, determination of hepatitis C virus (HCV) genotype could be routinely run in the future to tailor treatment schedules. The suitabilities of two versions of a serological, so-called serotyping assay (Murex HCV Serotyping Assay version 1-3 [SA1-3] and Murex HCV Serotyping Assay version 1-6 [SA1-6]; Murex Diagnostics Ltd.), based on the detection of genotype-sp...
In a prospective study of 33 infants born to hepatitis C virus (HCV)-positive human immunodeficiency virus-negative mothers the vertical transmission of HCV occurred in 6.8%. The evolution of HCV infection in two babies was studied from birth up to 5 or 6 years of age, and the sequencing of the hypervariable region (HVR) of the putative envelope-encoding E2 region of the HCV genome was performe...
A second generation assay for antibody to hepatitis C virus (anti-HCV) was used to screen 78 southern Indian individuals with a high risk of infection. RT-PCR targeted at the 5' end untranslated region (5'UTR) of the HCV genome was used to evaluate evidence of viraemia in 32 anti-HCV positive sera. The PCR products amplified from the 5'UTR of the HCV genome from 24 patients were sequenced, reve...
