GB virus C/hepatitis G virus groups and subgroups: classification by a restriction fragment length polymorphism method based on phylogenetic analysis of the 5' untranslated region.
نویسندگان
چکیده
A phylogenetic tree based on 150 5' untranslated region sequences deposited in GenBank database allowed segregation of the sequences into three major groups, including two subgroups, i.e., 1, 2a, 2b, and 3, supported by bootstrap analysis. Restriction site analysis of these sequences predicted that HinfI and either AatII or AciI could be used for genomic typing with 99.4% accuracy. cDNA sequencing and subsequent alignment of 21 Argentine GB virus C/hepatitis G virus strains confirmed restriction fragment length polymorphism patterns theoretically predicted. This method may be useful for a rapid screening of samples when either epidemiological or transmission studies of this agent are carried out.

Genomic and phylogenetic analysis of hepatitis C virus isolates from argentine patients: a six-year retrospective study.
Typing of hepatitis C virus (HCV) isolates from Argentine patients was performed by using different methodologies in a population of 243 patients. HCV subtype was assigned based upon restriction fragment length polymorphism (RFLP). HCV RNA genomes obtained from serum samples were classified as belonging to clade 1 (53.5%), 2 (23. 0%), or 3 (8.6%); 14.8% of samples showed HCV mixed infections, m...

Introduction: Hepatitis D virus (HDV) is a 35 nm in diameter agent that depends on hepatitis B surface antigen in order to proliferate and accumulate. Infection with delta agent can occur spontaneously with hepatitis B virus infection and it cause acute hepatitis or develop as secondary infection in the patients with hepatitis B. Hepatitis D virus (HDV) has several genotypes based on genome seq...

Background and Aim: Cytokines are believed to play an important role in the regulation of cellular immune response in hepatitis B virus infection. Interleukin 10 is a member of cytokine family. The overall expression of these molecules is mainly controlled by single nucleotide polymorphisms at specific sites on the promoter region of the Interleukin 10 gene. The aim of this study was to a...

Introduction: Hepatitis B virus (HBV) infection is a major health problem worldwide and may lead to serious clinical complications, including chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. The host’s genetic background in immune system genes is a crucial etiologic factor in progression of HBV infection to chronic disease or clearance of the virus from the body. Interleu...

INTRODUCTION Molecular biology procedures to detect, genotype and quantify hepatitis C virus (HCV) RNA in clinical samples have been extensively described. Routine commercial methods for each specific purpose (detection, quantification and genotyping) are also available, all of which are typically based on polymerase chain reaction (PCR) targeting the HCV 5' untranslated region (5'UTR). This st...
