    Maedi Visna (MV) virus infection is becoming more commonly diagnosed as a cause of major production and economic losses in commercial flocks and is an increasing threat to the UK sheep industry. The importance of MV accredited flocks should not be understated. Abstract: Maedi and visna are contagious sheep diseases which were introduced into Iceland in by imported sheep of Karakul breed. Maedi, a slowly progressing pneumonia, and the central nervous system disease visna were shown to be transmissible in sheep and most likely caused by a virus.

Visna virus (also known as Visna-maedi virus, Maedi-visna virus and Ovine lentivirus) from the genus Lentivirus and subfamily Orthoretrovirinae, is a "prototype" retrovirus that causes encephalitis and chronic pneumonitis in sheep.

It is known as visna when found in the brain, and maedi when infecting the lungs. Lifelong, persistent infections in sheep occur in the lungs, lymph nodes, spleen Family: Retroviridae.

Maedi-visna (MV) (also known as ovine progressive pneumonia, OPP) is an incurable viral disease of sheep with very long incubation period that leads to life-long infection [].It is caused by non-oncogenic exogenous retroviruses [], namely, maedi-visna virus (MVV) and caprine arthritis-encephalitis virus (CAEV), both belonging to a subgroup of viruses known as small ruminant lentiviruses (SRLVs).

3 Summary - The maedi-visna virus (MVV) is classified as a lentivirus of the retroviridae family. The genome of MVV includes three genes: gag, which encodes for group-specific antigens; pol, which encodes for reverse transcriptase, integrase, RNAse H, protease and dUTPase and env, the gene encoding for the surface glycoprotein responsible for receptor binding and.

It was originally a significant cause of death in the epizootic of maedi-visna that occurred in Iceland from to Maedi-visna (MV) in sheep is caused by maedi-visna virus (MVV), a small ruminant lentivirus (SRLV) that causes chronic infection and inflammatory lesions in infected animals.

Pneumonia and mastitis are its predominant clinical manifestations, and the tissues infected by MVV are mainly the lungs, the mammary gland, the nervous system and the joints. Introduction. Visna-maedi, one of the so-called slow viral diseases of sheep, is caused by a non-oncogenic retrovirus of the Lentivirus Icelandic name denotes the two most common forms of the disease, maedi referring to the respiratory form of the disease (“breathlessness”, chronic interstitial pneumonia) and visna referring to the neurologic form of the disease (“wasting.
