Diagnosing limb paresis and paralysis in sheep

In Practice, Volume 37, Issue 10, Page 490-507, November 2015., 2015
Paresis and paralysis are uncommon problems in sheep but are likely to prompt farmers to seek veterinary advice. A thorough and logical approach can aid in determining the cause of the problem and highlighting the benefit of veterinary involvement. While this may not necessarily alter the prognosis for an individual animal, it can help in formulating ...

Advances in Diagnosis of Respiratory Diseases of Small Ruminants

Veterinary 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 ...

Worldwide prevalence of small ruminant lentiviruses in sheep: A systematic review and meta-analysis [PDF]

, 2021
Small Ruminant Lentiviruses (SRLV) are highly prevalent retroviruses with significant genetic diversity and antigenic heterogeneity that cause a progressive wasting disease of sheep called Maedi-visna.

Complex Codon Usage Pattern and Compositional Features of Retroviruses

Computational 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 Polytropic Caprine Arthritis Encephalitis Virus Promoter Isolated from Multiple Tissues from a Sheep with Multisystemic Lentivirus-Associated Inflammatory Disease [PDF]

, 2013
Caprine arthritis encephalitis virus (CAEV) is a lentivirus that infects both goats and sheep and is closely related to maedi-visna virus that infects sheep; collectively, these viruses are known as small ruminant lentiviruses (SRLV).

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

BioMed 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.

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 ...
