Hepatitis B virus. Coloured transmission electron micrograph (TEM) of the Hepatitis B virus and its naturally occurring antigen. The rounded spheres (called Dane particles) are the complete virus. Hepatitis B virus occurs typically in clusters of three types of particles (as seen here): the virus itself,with smaller spheres and rod-shaped forms made from the protein coat of the virus. The smaller non-infectious spheres are antigenically identical to the virus,and provide raw material for Hepatitis B vaccines. Infection by this virus is more serious than Hepatitis A,can be sexually transmitted,and causes chronic hepatitis | |
