Association of TMEM154 variants with visna/maedi virus infection in Turkish sheep

Small Ruminant Research, 2019
Abstract Visna/maedi (VM) is a multisystemic disease of sheep characterized by persistent lentiviral infection, slow progression and eventually death. The VM virus (VMV) affects sheep throughout the world and is the focus of national eradication campaigns.

Ovine aortic smooth muscle cells allow the replication of visna-maedi virus in vitro

Archives of Virology, 1995
Visna-maedi virus induces in sheep an interstitial lung disease characterised by an accumulation of smooth muscle cells (SMC) or myomatosis. Infection by HIV-1 has been recently associated with disorders of the vessel-derived cells: primary pulmonary hypertension, coronary artery disease and smooth muscle tumors in humans. We hypothesized that, besides

Isolation of visna-maedi virus from the choroid plexus of an apparently healthy sheep in Italy

Veterinary Research Communications, 1985
In 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.

Association of CD80 and CD86 Expression Levels with Disease Status of Visna/Maedi Virus Infected Sheep

Viral Immunology, 2007
In small ruminant lentivirus infections, cellular immune responses are diminished in clinically affected animals. The underlying mechanisms for this are unknown. In this study, we tested the hypothesis that alterations in expression of the co-stimulatory molecules B7-1 and B7-2 are involved in infections with Visna/Maedi virus (VMV), the prototype ...

Characterization of the immunodominant cross-reacting epitope of visna maedi virus and caprine arthritis-encephalitis virus capsid antigen

Virus Research, 1999
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

Visna/Maedi virus genetic characterization and serological diagnosis of infection in sheep from a neurological outbreak

Veterinary Microbiology, 2012
An extensive outbreak characterized by the appearance of neurological symptoms in small ruminant lentivirus (SRLV) infected sheep has been identified in Spain, but the genetic characteristics of the strain involved and differential diagnostic tools for this outbreak remain unexplored.

Presence of a unique parainfluenza virus 3 strain identified by RT-PCR in visna-maedi virus infected sheep

Veterinary Microbiology, 1997
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 ...

[Detection of visna-maedi virus antibodies and antigens by immunoblotting].

Annales de recherches veterinaires. Annals of veterinary research, 1989
The visna-maedi virus was immunologically diagnosed using an immunoblotting technique from an antigenic preparation of the visna-maedi virus K796 purified by sucrose density gradient centrifugation. After SDS-PAGE electrophoresis and transfer onto a nitrocellulose sheet, the immunoblotting procedure was adapted to the search for specific antibodies in ...

La pathogenese du virus Visna-Maedi : modèle expérimental pour l'étude des Lentivirinae

Médecine et Maladies Infectieuses, 1987
Resume 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
