Genetic Diversity of Hepatitis B Virus Strains Derived Worldwide: Genotypes, Subgenotypes, and HBsAg Subtypes
Sequences of 234 complete genomes and 631 hepatitis B surface antigen genes were used to assess the worldwide diversity of hepatitis B virus (HBV). Apart from the described two subgenotypes each forExpand

Genetic relatedness of hepatitis A virus strains recovered from different geographical regions.
A pairwise comparison of the nucleic acid sequence of 168 bases from 152 wild-type or unique cell culture-adapted strains of hepatitis A virus (HAV) revealed that HAV strains can be differentiatedExpand

Genotype H: a new Amerindian genotype of hepatitis B virus revealed in Central America.
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 wereExpand

A broadly reactive one-step real-time RT-PCR assay for rapid and sensitive detection of hepatitis E virus.
Hepatitis E virus (HEV) is transmitted by the fecal-oral route and causes sporadic and epidemic forms of acute hepatitis. Large waterborne HEV epidemics have been documented exclusively in developingExpand

The epidemiology and iatrogenic transmission of hepatitis C virus in Egypt: a Bayesian coalescent approach.
Hepatitis C virus (HCV) is a leading cause of liver cancer and cirrhosis, and Egypt has possibly the highest HCV prevalence worldwide. In this article we use a newly developed Bayesian inferenceExpand

Hepatitis C virus genotype distribution in China: Predominance of closely related subtype 1b isolates and existence of new genotype 6 variants
To determine hepatitis C virus (HCV) genotype distribution in China, a total of 148 HCV RNA positive serum samples were collected from nine geographic areas and subjected to RT‐PCR followed by directExpand

Hepatitis B virus genotype assignment using restriction fragment length polymorphism patterns
Hepatitis B virus (HBV) is classified into genotypes A–F, which is important for clinical and etiological investigations. To establish a simple genotyping method, 68 full‐genomic sequences and 106 SExpand

Hepatitis E virus antibody prevalence among persons who work with swine.
Prevalence of antibody and risk factors to hepatitis E virus (HEV) infection were determined in a cross-sectional study of 2 group-matched populations: swine farmers (n=264) and persons withoutExpand

Nucleotide and amino acid sequence coding for polypeptides of foot-and-mouth disease virus type A12.
The coding region for the structural and nonstructural polypeptides of the type A12 foot-and-mouth disease virus genome has been identified by nucleotide sequencing of cloned DNA derived from theExpand

Epidemiologic patterns of wild-type hepatitis A virus determined by genetic variation.
Hepatitis A virus (HAV) isolates from different parts of the world are a single serotype. However, genetic analysis of the VP1 genome region of published HAV sequences suggested that distinctExpand
