  • Hepatitis B

    Hepatitis B is an inflammation of the liver, caused by the Hepatitis B virus[1], and characterized by diffuse or patchy areas of necrosis[2]. Hepatitis studies that classified the types of Hepatitis began after World War II (1945)[3] just over 70 years ago. Two decades later in 1967, Krugman studies found Hepatitis A and Hepatitis B[3]. Another ten years later, the Prince studies found the specific virus surface antigen that causes Hepatitis B[3]. Taxonomically classified in the Hepadnaviridae family, the Hepatitis B virus mostly affects the liver, but may also affect the kidney, pancreas and mononuclear cells[3]. Structurally, the virus is a double-shelled particle, with an outer lipoprotein envelope that has 3 surface antigens[3]. Replication of the virus occurs via replication in host cells, and the pathophysiology of the immune response is not completely understood.[3] Hepatitis B…

    Globally individuals develop and obtain disease. Among these diseases is the hepatitis B virus (HBV) and breast cancer; two commonly spread/carried diseases, and potentially life threatening diseases.

  • Hepatitis B Virus (HBV)

    The core of the hepatitis B virus is generally in the shape of an icosahedron. Within the virus, there are two strands of DNA, one smaller than the other, which is circular. HBV is around 42 nm in width, and the core is surrounded in a 4nm thick coat. They are enveloped, which means they are more susceptible to being destroyed, because the envelope is very thin. Viruses in general are very small, much smaller than bacteria, and HBV is no different. (Image:…

  • Hepatitis B Summary

    Hepatitis B (HBV) is a viral disease of the liver, discovered by Dr. Baruch S. Blumberg in 1967. As a medical anthropologist, a doctor who studies human health and disease, Blumberg was very interested in the genetics of disease susceptibility. He started a study to see if inherited traits made different groups of people differently susceptible to the same disease. He and his team collected blood samples from around the world, and planned to look for gene differences, and see if the differences…

  • Hepatitis B Virus: A Case Study

    The Microbe Hepatitis B virus belongs to a group called, Hepadnaviridae which consists of diseases that contain deoxyribonucleic acid (DNA) and affect the liver. Hepatitis B is a virus therefore; hepatitis B requires a living host to replicate viral particles. Hepatitis B consists of a nucleic acid core, a protein coat, and a lipid envelope. The hepatitis B virus contains a partially double-stranded DNA within the nucleic acid core because one of the full-length strands is linked to the viral…

    The recombinant hepatitis B vaccine is produced from genetically engineered Saccharomyces cerevisiae, a yeast. The vaccine is noninfectious, and it contains hepatitis B surface antigen (HBsAg) (Keating & Noble, 2003). The first recombinant hepatitis B vaccine, Recombivax HB, was approved by the Food and Drug Administration in 1983, followed by Engerix-B in 1989 (Hepatitis B Vaccine Safety, n.d.). safety.
