Vaccination delays maedi-visna lentivirus infection in a naturally-infected sheep flock

open access: yesBMC Veterinary Research, 2013
Background The Maedi-Visna (MV) lentivirus causes two slowly progressive eventually fatal diseases of sheep, Maedi, a progressive interstitial pneumonia, and Visna, a progressive demyelinating disease of the central nervous system.

PREVALENCE OF MAEDI-VISNA IN SHEEP HERDS

open access: yesArchives 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.

Mapping and characterization of visna/maedi virus cytotoxic T-lymphocyte epitopes

open access: yesJournal of General Virology, 2008
CD8+cytotoxic T-lymphocyte (CTL) responses have been shown to be important in the control of human and simian immunodeficiency virus infections. Infection of sheep with visna/maedi virus (VISNA), a related lentivirus, induces specific CD8+CTLin vivo, but the specific viral proteins recognized are not known.

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

open access: yesJournal 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.

Oxidant-antioxidant imbalance in the experimental interstitial lung disease induced in sheep by visna-maedi virus [PDF]

open access: yesEuropean Respiratory Journal, 1996
Infection of sheep by visna-maedi virus causes an interstitial pneumonitis similar to that associated with human immunodeficiency virus type-1 (HIV-1). Visna-maedi virus infection of alveolar macrophages leads to their activation. In this study we determined whether an imbalance in oxidant-antioxidant activity may be involved in the pathogenesis of the

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]

open access: yesPesquisa 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.

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

open access: yesSpanish 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.

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

open access: yesJournal 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.

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

open access: yesVeterinární 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.

Neopterin, β2-Microglobulin and Carbohydrate Antigen CA-19-9 in Sporadic Adult Amyotrophic Lateral Sclerosis

open access: yesPteridines, 1993
In 38 patients diagnosed as adult sporadic amyotrophic lateral sclerosis (ALS), and negative for relevant anti -ganglioside, anti-borrelia or anti-Boma disease virus antibodies, we determined serum concentrations of neopterin, ~rmicroglobulin ...
