The complete genomes were sequenced for ten hepatitis B virus (HBV) strains. Two of them, from Spain and Sweden, were most similar to genotype D, although encoding d specificity. Five of them were from Central America and belonged to genotype F. Two strains from Nicaragua and one from Los Angeles, USA, showed divergences of 3.1-4.1% within the small S gene from genotype F strains and were recog...

BACKGROUND Hepatitis B virus (HBV), hepatitis D virus (HDV), and human immunodeficiency virus (HIV) are transmitted by blood transfusion. Thus, hemodialysis (HD) patients are more prone to become the carriers of these infections due to their treatment demands. OBJECTIVES The aim of this study was to assess the prevalence of HBV and HIV infections among HD patients in Bandar Abbas, Iran, 2015....

INTRODUCTION Hepatitis B virus (HBV) infection in hemodialysis (HD) patients is a major concern, but limited information exists on the HBV genotyping in patients on maintenance HD in Turkey. AIM To investigate the genotype and subgenotype distribution of HBV in Turkish HD patients with chronic hepatitis B. MATERIAL AND METHODS A total of 248 HBsAg positive patients undergoing long-term HD f...

conclusions the b3, b5, b7, b8 and b9 subgenotypes can be clustered into quasi-sub-genotype b3 and the open reading frame of hbv has a start codon preference; however, whether a mutation in the start codon in the pre-s2 region has an impact on survival and replication of hbv remains to be determined. background the number of cases of hbv infection reported by the who for each district and count...

This study aimed to estimate the distribution of hepatitis B virus (HBV) C/D recombinant in Han and Tibet patients with chronic hepatitis B (CHB) and then learn such strain's replication capacity in vivo. A total of 331 serum samples were collected from Han outpatients from Sichuan Province and Tibetan outpatients from Tibet. Viral genotypes in these samples were identified. An HBV replicative ...

Background & Aims HBV genotype G (HBV/G) is mainly found in co-infections with other genotypes and was identified as an independent risk factor for liver fibrosis. This study aimed to analyse the prevalence of HBV/G healthy European carriers characterize crosstalk genotypes. Methods A total 560 were tested via HBV/G-specific PCR co-infections. Quasispecies distribution analysed deep sequencing,...

Abstract Eritrea is an East African multiethnic country with intermediate endemicity for hepatitis B. Our aim was to establish the most prevalent genotypes of B virus (HBV) among patients liver disease. A total 293 Eritrean disease who were surface antigen (HBsAg) positive enrolled. All sera tested transaminases, HBV DNA viral load, and seromarkers including HBsAg, anti-HBcAb (total), HBeAg, an...

background and aims: hepatitis b virus (hbv) infects the liver and causes acute and chronic hepatitis, hepatocellular carcinoma and cirrhosis. hbv has been divided to eight genotypes (a–h) and subgenotypes of a, b, c and f. for the first time, we determined hbv genotypes in infected samples by inno-lipa method in yazd, central province of iran. materials and methods: this study was performed on...

Various domains of hepatitis B surface antigen (HBsAg) are essential for the assembly and secretion of hepatitis D virus (HDV). This study investigated the influences of the levels and sequences of HBsAg of naturally occurring HBV variants on the assembly and secretion of HDV. Six hepatitis B virus (HBV)-producing plasmids (three genotype B and three genotype C) and six HBsAg expression plasmid...

OBJECTIVE To identify the distribution pattern of Hepatitis B Virus (HBV) genotype in a group of patients and to study its phylogenetic divergence. STUDY DESIGN An observational study. PLACE AND DURATION OF STUDY The clinics of Gastroenterology Unit, Ziauddin University, from January to December 2006. METHODOLOGY Two hundred and one HBV infected patients were genotyped for this study. All...
