AZT inhibits Visna/maedi virus-induced apoptosis
Archives of Virology, 2004Visna/maedi virus (VMV) causes severe encephalitis and a progressive demyelinating disease in sheep. Previous in vitro studies have demonstrated that VMV-infection leads to apoptosis in sheep choroid plexus cells (SCPC) via induction of both intrinsic and extrinsic pathways with subsequent activation of caspases.

Maedi visna (MV) and caprine arthritis-encephalitis (CAE) are two retroviral infections distributed world wide. Antigenic cross reactions between the viruses have been demonstrated in gag and env encoded structural proteins. Antigens from ovine lentiviruses are easier to produce in cell culture systems and therefore have been used in the development of

The mechanisms leading to the severe lung damage seen in some sheep naturally infected with the visna-maedi virus, and to pulmonary lesions in other lentiviral diseases, appear to involve the recruitment of large numbers of uninfected inflammatory cells.

The presence in farm sheep of a paramyxovirus closely related to parainfluenza virus type 3 (Pi3) from humans or cattle was confirmed using RT-PCR on RNA samples from lung cells from slaughtered animals. Sequencing and restriction enzyme patterns of the amplified fragment of the F gene confirms the distinctness of the isolate, and suitable PCR primers ...

Visna-maedi virus is a lentivirus closely related to the human immunodeficiency virus type I (HIV-I). During spontaneous infection of sheep by Visna-maedi virus an interstitial lung disease is observed. It is characterized by an alveolitis, peribronchovascular lymphoid nodules, alveolar wall thickening and myomatosis. In order to decipher the pathology

A cross-sectional study was carried out to determine Visna/Maedi virus (VMV) seroprevalence and risk factors in semi-intensive lamb-producing flocks as a prelude to establishing a monitoring program in northwestern (NW) Spain. A total of 15,155 serum samples were taken from 78 commercial flocks and were submitted to an indirect VMV ELISA.

Isolation of visna-maedi virus from the choroid plexus of an apparently healthy sheep in Italy
Veterinary Research Communications, 1985In this paper, the presence of visna-maedi in Italy, reported to exist since 1982 on clinical grounds, and the presence of anti-visna-maedi antibody is confirmed by the isolation of the viral agent from choroid plexus cells of an apparently healthy sheep.

Sheep naturally infected by visna-maedi virus often develop a chronic interstitial lung disease characterized by an alveolitis comprising lymphocytes, neutrophils and macrophages. The alpha chemokine interleukin-8 (IL-8) was detected in cell free bronchoalveolar lavage fluid from naturally infected animals, confirmed by RT-PCR, presenting typical ...

La pathogenese du virus Visna-Maedi : modèle expérimental pour l'étude des Lentivirinae
Médecine et Maladies Infectieuses, 1987Resume La pathogenese des Lentivirinae est liee a l'ambiguite pathologique des maladies progressives, lentes, causees par des Retrovirus non oncogenes. Le tropisme de ces virus pour certaines cellules, macrophages pour le Visna-Maedi, CAEV et AIEV, lymphocytes pour le HIV, est du a la presence de recepteurs cellulaires. La maturation ou stimulation
