Simian immunodeficiency virus. Colour transmission electron micrograph of simian immunodeficiency viruses (SIV) in bone marrow culture. The viruses are the small yellow/green bodies with dark centres. The dark centres are nucleoids,which contain the genetic material of the viruses. The culture cell is lying adjacent to a white blood cell,the boundary (red) of which runs diagonally across the image at top left. SIV causes an AIDS- like disease in monkeys. It is thought to be related to the recently discovered,second AIDS (Acquired Immune Deficiency Syndrome) virus,HIV-2 (Human Immunodeficiency Virus type 2).
