Six new isolates of human immunodeficiency virus type 2 (HIV-2) and the molecular characterization of one (HIV-2CAM2)

Summary We report the isolation of human immunodeficiency virus type 2 (HIV-2) from each of six West Africans with AIDS-related complex or AIDS. One isolate (HIV-2CAM2) was molecularly cloned and shown by restriction mapping to differ in seven out of 22 sites from the prototype HIV-2ROD. Nevertheless, by a number of serological criteria these isolates are all clearly HIV-2.
