Hepatitis B virus genotypes.
Eight genotypes of hepatitis B virus (A-H) are currently recognized, and subgenotypes have recently been described in four of these genotypes (A, B, C and F). The genotypes show a distinctExpand

A unique segment of the hepatitis B virus group A genotype identified in isolates from South Africa.
The preS2/S genes of hepatitis B virus isolated from 29 acutely or chronically infected individuals in the Gauteng province of South Africa were sequenced. Phylogenetic analysis of these sequences inExpand

Relationship of serological subtype, basic core promoter and precore mutations to genotypes/subgenotypes of hepatitis B virus
Using phylogenetic analysis and pairwise comparison of 670 complete hepatitis B virus (HBV) genomes, we demonstrated that nucleotide divergence greater than 7.5% can be used to separate strains intoExpand

Outbreake of Marburg virus disease in Johannesburg.
The first recognised outbreak of Marburg virus disease in Africa, and the first since the original epidemic in West Germany and Yugoslavia in 1967, occurred in South Africa in February 1975. TheExpand

Functional consequences of frizzled-7 receptor overexpression in human hepatocellular carcinoma.
BACKGROUND & AIMS The molecular pathogenesis of human hepatocellular carcinoma (HCC) is understood poorly. In some tumors, activation of the Wnt/beta-catenin pathway as a result of beta-catenin geneExpand

Hepatitis B virus and human immunodeficiency virus co‐infection in sub‐Saharan Africa: a call for further investigation
Abstract: A growing body of evidence indicates that human immunodeficiency virus (HIV)‐positive individuals are more likely to be infected with hepatitis B virus (HBV) than HIV‐negative individuals,Expand

The core promoter of hepatitis B virus
The core promoter (CP) of hepatitis B virus (HBV) plays a central role in HBV replication and morphogenesis, directing the transcription of both species of 3.5 kb mRNA: pregenomic (pg) RNA andExpand

High prevalence of 1762T 1764A mutations in the basic core promoter of hepatitis B virus isolated from black africans with hepatocellular carcinoma compared with asymptomatic carriers
The purpose of this study was to identify mutations in the basic core promoter and enhancer II region of the hepatitis B virus (HBV) that might cause the HBV e antigen (HBeAg)‐negative phenotype andExpand
