AIDS viruses. Coloured transmission electron micrograph (TEM) of rounded Human Immunodeficiency viruses (HIV) budding from the surface of an infected T-lymphocyte blood cell (T-cell). HIV is the causative agent of AIDS (Acquired Immune Defi- ciency Syndrome). At top are clusters of virus particles. Part of the cell is seen at lower frame with its granular cell contents. After infection, HIV instructs the cell to reproduce more viruses which bud away from the cell. By this process the T-cell of the blood immune system dies. Lower numbers of T-cells is the main reason for the destruction of a person's immune system in AIDS. Magnification: x10,850 at 5x7cm size.
