PREVALENCE OF MAEDI-VISNA IN SHEEP HERDS

Archives of Veterinary Medicine, 2008
Progressive sheep pheumonia and maedi are terms that denote chronic virus sheep disease. Maedi-visna virus causes a disease named visna, which is a disease of nervous system with the symptoms of paresis and paralyses.

Experimental infection of sheep with visna/maedi virus via the conjunctival space

Journal of General Virology, 2008
Experiments were performed to determine whether visna/maedi virus (VMV), a small ruminant lentivirus (SRLV), could infect sheep via ocular tissues. The EV1 strain of VMV was administered into the conjunctival space of uninfected sheep, and the animals monitored for the presence of provirus DNA and anti-VMV antibodies in blood.

Comparison of immunoassay and real-time PCR methods for the detection of Jembrana disease virus infection in Bali cattle [PDF]

, 2009
A sensitive diagnostic assay for the detection of infections with the bovine lentivirus Jembrana disease virus (JDV) is required in Indonesia to control the spread of Jembrana disease. Immunoassays are used routinely but are compromised by cross-reactive

Produção de antígeno nucleoprotéico do vírus da artrite-encefalite caprina e comparação com o do vírus Maedi-Visna para utilização em teste de imunodifusão em ágar gel [PDF]

Pesquisa Veterinária Brasileira, 1998
Foi feita uma comparação entre os antígenos (Ag), preparados a partir dos vírus Maedi-Visna (MVV) e Artrite-encefalite Caprina (CAEV) para detecção de anticorpos contra o CAEV em 120 amostras de soro caprino.

Mutational analysis of a principal neutralization domain of visna/maedi virus envelope glycoprotein

Journal of General Virology, 2008
We have shown previously that a type-specific neutralization domain is located within a 39 aa sequence in the fourth variable domain of gp135 in visna/maedi virus. We now show that neutralizing antibodies detected early in infection are directed to this epitope, suggesting an immunodominant nature of this domain.

Characterization of the lymphocytic alveolitis in visna-maedi virus-induced interstitial lung disease of sheep [PDF]

Clinical and Experimental Immunology, 1992
SUMMARYIn order to investigate the contribution of lymphocytes to interstitial lung disease in animals with visna-maedi infection, we studied in parallel bronchoalveolar cells and lung tissue from slaughterhouse animals (n = 29) and from colostrum-deprived lambs transtracheally inoculated with field isolates of visna-maedi virus (n = 9) or saline (n ...

Lack of relationship between Visna/maedi infection and scrapie resistance genetic markers

Spanish Journal of Agricultural Research, 2014
The relationship between Visna/maedi virus (VMV) antibody status and scrapie genetic resistance of 10,611 Rasa Aragonesa sheep from 17 flocks in Aragón (Spain) was investigated.

Etiology, Epizootiology and Control of Maedi-Visna in Dairy Sheep: A Review

Animals, 2020
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.

Purification of Escherichia coli-expressed HIS-tagged Maedi-Visna p25 core antigen by Ni2+-chelate affinity chromatography

Veterinární Medicína, 2001
In this study, recombinant histidine tagged p25 capsid protein of Maedi-Visna virus was developed. Part of the viral genome coding p25 protein was positioned downstream and in frame with a metal binding domain in pRSET-B vector.
