Genetic variability in hepatitis B viruses.
In 1988, it was reported that the full nucleotide sequences of 18 hepatitis B virus (HBV) strains clustered into four genetic groups (A to D) with more than 8% divergence between the groups. This classification of strains in terms of genome sequence has since proven to be an important tool in the understanding of HBV epidemiology and evolution and has been expanded to include three more genotyp...
متن کاملSeroprevalence of Hepatitis A and Hepatitis B Viruses Among Blood Donors in North of Iran
Background and Objective: Hepatitis A virus (HAV) and hepatitis E virus (HEV) are both transmitted by the fecal-oral route and are known as leading causes of acute viral hepatitis in the world, especially in developing countries. There is a lack of updated data on HAV and HEV seroprevalence in the north of Iran. This study aimed to determine the seroprevalence of HAV and HEV among blood donors ...
متن کاملGenetic variability of Hepatitis B virus in Morocco
Results The mean age of patients was 44 ± 12.2. Most of them were HBeAg negative (90%). The mean HBV DNA was 475104 ± 160591 UI/mL. Phylogenetic analysis identified 90% isolates in genotype D and 10% in genotype A. Most genotypes D isolates belonged to subgenotype D7 (80%) followed by subgenotype D1 (25%) and one isolate belonged to subgenotype D2. All genotype A strains belonged to subgenotype...
متن کاملGenotypes and genetic variability of hepatitis B virus.
Sequence heterogeneity is a feature of hepatitis B virus (HBV), the prototype member of the family Hepadnaviridae. Based on an intergroup divergence of greater than 7.5% across the complete genome, HBV has been classified phylogenetically into 9 genotypes, A-I, with a putative 10th genotype 'J', isolated from a single individual. With between approximately 4 and 8% intergroup nucleotide diverge...
متن کاملDistribution of Genotypes of B and C Hepatitis Viruses in Guilan Province
Today, chronic viral hepatitis is considered as a public health problem in the world. Totally, 5% of the world population, especially in Asia and Africa suffer from this problem. The prevalence of acute hepatitis in America is 0.1-0.2 percent, 50% of those with hepatitis C (HCV) and 5-10% of them with hepatitis B (HCV) develop chronic hepatitis. Determining HBV and HCV genotypes is important to...
