AIDS viruses. Coloured scanning electron micrograph of HIV viruses (red dots) budding from a T- lymphocyte white blood cell (yellow & green). HIV (human immunodeficiency virus) is the cause of AIDS (acquired immune deficiency syndrome). The HIV has hijacked this lymphocyte and is forcing it to produce more viruses. This budding process destroys the white blood cell. The viruses then infect more T- lymphocytes, weakening the immune system and causing AIDS. The majority of the victims of AIDS die as a result of everyday infections which a healthy immune system would easily cope with. Magnification unknown.
