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.

Advances in Diagnosis of Respiratory Diseases of Small Ruminants

open access: yesVeterinary Medicine International, Volume 2014, Issue 1, 2014., 2014
Irrespective of aetiology, infectious respiratory diseases of sheep and goats contribute to 5.6 percent of the total diseases of small ruminants. These infectious respiratory disorders are divided into two groups: the diseases of upper respiratory tract, namely, nasal myiasis and enzootic nasal tumors, and diseases of lower respiratory tract, namely ...

Complex Codon Usage Pattern and Compositional Features of Retroviruses

open access: yesComputational and Mathematical Methods in Medicine, Volume 2013, Issue 1, 2013., 2013
Retroviruses infect a wide range of organisms including humans. Among them, HIV‐1, which causes AIDS, has now become a major threat for world health. Some of these viruses are also potential gene transfer vectors. In this study, the patterns of synonymous codon usage in retroviruses have been studied through multivariate statistical methods on ORFs ...

A Genome‐Wide Analysis of RNA Pseudoknots That Stimulate Efficient −1 Ribosomal Frameshifting or Readthrough in Animal Viruses

open access: yesBioMed Research International, Volume 2013, Issue 1, 2013., 2013
Programmed −1 ribosomal frameshifting (PRF) and stop codon readthrough are two translational recoding mechanisms utilized by some RNA viruses to express their structural and enzymatic proteins at a defined ratio. Efficient recoding usually requires an RNA pseudoknot located several nucleotides downstream from the recoding site.

Blood‐Brain Barrier Abnormalities Caused by HIV‐1 gp120: Mechanistic and Therapeutic Implications

open access: yesThe Scientific World Journal, Volume 2012, Issue 1, 2012., 2012
The blood‐brain barrier (BBB) is compromised in many systemic and CNS diseases, including HIV‐1 infection of the brain. We studied BBB disruption caused by HIV‐1 envelope glycoprotein 120 (gp120) as a model. Exposure to gp120, whether acute [by direct intra‐caudate‐putamen (CP) injection] or chronic [using SV(gp120), an experimental model of ongoing ...

Molecular characterization and phylogenetic analysis of small ruminant lentiviruses isolated from Canadian sheep and goats

open access: yesVirology Journal, 2011
Background Small Ruminant Lentiviruses (SRLV) are widespread in Canadian sheep and goats and represent an important health issue in these animals. There is however no data about the genetic diversity of Caprine Arthritis Encephalitis Virus (CAEV) or ...

Infection of Dendritic Cells by the Maedi-Visna Lentivirus [PDF]

open access: yesJournal of Virology, 2000
ABSTRACTThe early stages of lentivirus infection of dendritic cells have been studied in an in vivo model. Maedi-visna virus (MVV) is a natural pathogen of sheep with a tropism for macrophages, but the infection of dendritic cells has not been proven, largely because of the difficulties of definitively distinguishing the two cell types.

Serological diagnostic of maedi-visna (MVV) in sheep and caprine arthritis encephalitis virus (CAEV) in goats in Macedonia [PDF]

open access: yesMacedonian Veterinary Review, 2009
Maedi-Visna in sheep and CAEV in goats are diseases caused by lentiviruses with very similar antigenic characteristics. This diseases are very important for the animal husbandry because of the economical losses they cause (reduced milk yield, lower body ...
