  2. 1. 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.

  4. 2. 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

  5. 3. Immune modulation in chronic HBV and HCV infection

    Author : Catharina Hultgren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HBV; HBeAg; HCV; NS3; chronic infection; humoral cellular immune response; Th1 Th2 cells; proliferative response;

    Abstract : Chronic viral hepatitis is a major health problem worldwide. The two major viral causes for chronic hepatitis are the hepatitis B (HBV) and C viruses (HCV). HBV is a DNA virus with a rather limited genetic variability whereas HCV is an RNA virus with a high genetic variability. READ MORE

  6. 4. Molecular epidemiology of hepatitis A, B and C in Estonia

    Author : Tatjana Tallo; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HAV; HBV; HCV; strains; genotype; phylogenetic analysis;

    Abstract : During the last decade changes have occurred in the epidemiology of hepatitis A, B and C in Estonia. A shift from high to intermediate endemicity for HAV has led to a shift in age of susceptible individuals from children to adolescents and adults. READ MORE
