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 …

Molecular biology-based assays are invaluable tools for the management of chronic viral
hepatitis. They can be used to test blood donations, diagnose active infection, help to …

Background & Aims: Recent studies suggest that hepatitis B virus (HBV) genotype B is
associated with less active liver disease than HBV genotype C. The aim of our study was to …

The goals of this retrospective study were to determine whether there is a threshold hepatitis
B virus (HBV) DNA value associated with spontaneous or antiviral therapy–related hepatitis …

There are eight genotypes of HBV designated A to H based on greater than 8% nucleotide
variation over the entire genome. Hepadnaviruses infecting primates like the chimpanzee …

Abstract Background Hepatitis B virus (HBV) isolates have been classified in eight
genotypes, A to H, which exhibit distinct geographical distributions. Genotypes A, D and F …

ABSTRACT A method for genotyping hepatitis B virus by partial HBsAg gene sequencing
with primers common to all known genotypes was developed. Mutations related to anti-HBs …

Some people who are receiving dialysis treatment have virus infection such as hepatitis B,
hepatitis C and/or HIV that is present in their blood. These infections can be transmitted to …

Background Patients under haemodialysis are considered at high risk to acquire hepatitis B
virus (HBV) infection. Since few data are reported from Brazil, our aim was to assess the …

Background: Patients on maintenance dialysis typically show a suboptimal immune
response to hepatitis B virus vaccine compared with the non‐uraemic population. A variety …
