title: [Visna and AIDS--various comparative aspects].
abstract: Visna, a lingering meningo-encephalitis in sheep, was one of the diseases on which B. Sigurdsson based his theory of a special group of disorders called slow infections. The cause of the disease, a retrovirus, was isolated in 1957. Visna is now classified in a subgroup of retroviridae, lentivirinae, together with virus types in animals and the human immune deficiency virus HIV. Notwithstanding that Visna has been eradicated among Icelandic sheep for 25 years research into this virus continues since it bears many similarities to HIV and also MS.
