  2. 1. The hepatitis B virus – Insights into genetic variability, evolution and Bayesian phylogeographic inference

    Author : Mikael Ingman; Malmö Klinisk virologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hepatit B; evolutionsbiologi; fylogeni; Hepatitis B; evolutionary dynamics; Phylogeography;

    Abstract : In terms of genome size, the hepatitis B virus is the smallest virus known to infect humans and its compactness with multiple overlapping reading frames puts restraints on the emergence of mutations. In the papers included in this thesis we aimed to investigate genetic variation within the precore and core promoter region and to describe the origin, spread and diversification of HBV genotype A.

  4. 2. Geographic and genetic diversity of hepatitis B

    Author : Erik Alestig; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hepatitis B virus; genotype; phylogeny; molecular epidemiology; sequence analysis; mutation;

    Abstract : Hepatitis B Virus (HBV) infection is a global health problem and may lead to chronic hepatitis, liver cirrhosis and hepatocellular cancer. The ability of HBV to adapt to the host environment by genetic variation has lead to the evolution of 8 established (A-H) and 2 putative genotypes (I-J), each corresponding to a rather well-defined geographical distribution.

  5. 3. Genetic variability of hepatitis B virus in chronic infection

    Author : Charles Hannoun; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hepatitis B virus; mutation; genotype; phylogeny; ; Recombination; coinfection; interferon; response;

    Abstract : Chronic hepatitis B is a major health problem, and may lead to cirrhosis and hepatocellular carcinoma. The liver damage in hepatitis B virus (HBV) infection is considered to be a result of the immune response, and not a cytopathic effect of the virus itself. READ MORE

  6. 4. Prevention and treatment of hepatitis B virus infection

    Author : Per Sangfelt; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Hepatitis B virus; vaccination; treatment; interferon-alpha; larnivudine; famciclovir;

    Abstract : Despite 25 years of effective vaccines and availability of treatment options for 15 years, hepatitis B virus (HBV) infections continue to be a major global health problem. In Sweden, selective screening and vaccination programmes are used in defined high-risk groups such as newborns of chronic HBV carrier mothers and health care workers with risk of blood exposure.

  7. 5. Studies on Hepatitis B Vaccination and Factors Associated with the Vaccine Response

    Author : Kristina Cardell; Aril Frydén; Matti Sällberg; Clas Ahlm; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Hepatitis B virus causes liver disease and up to 2 billion people have been in contact with the virus world wide. It can cause both acute and chronic disease. The routes for transmission are through blood, mother to infant at time of delivery and sexually. READ MORE
