Maedi-Visna, Aids of sheep

16.10.2002


The disorder Maedi-Visna that is detected in sheep affects on mammary gland. As it says in the source language, Icelander, it affects lungs and nervous system. The disorder is produced by the lentivirus Maedi-Visna, which belongs to the family of Aids. This virus infects sheep, and until now, there is no evidence of the transmission to humans. This virus, which is known since many years, causes a very slow evolution of the disorder. Therefore, shepherds often do not detect the infection, because sheep die before the disease develops.



In the consensus conference held last September, experts on immunology, diagnosis, prevision and epidemiology of Maedi-Visna disorder participated. Among them we would like to mention the participation as an expert of Beatriz Amorena from the Public University of Navarre, Basque Country. All of them gave the reasons for the need to set a control programme for this disorder. Evidences produced by this disorder were also presented: financial consequences derived from a lower production of cattle caused by the lentivirus and the need to reinforce the health of cattle.

In the meeting representatives of 18 countries participated. In fact, it has been the first strategic action of consensus in the European Union about animal disease and in which the criteria “medicine based on evidence” has been applied. However, these kinds of actions are common in case of human diseases.


Researches to develop a vaccine in Pamplona

The Institute of Agrobiotechnology and Natural Resources of Navarre is actually working on three research projects about Maedi-Visna: two European projects and a national one. Those projects are carrying out under the supervision of Beatriz Amorena.

One of the European projects is the “Evaluation of Strategies on DNA Vaccine against the virus in sheep”. The aim of that research is to analyse the behaviour of the immune system against the virus, which vaccine strategies improve the immune response and which responses may be related to the protection against Maedi-Visna. In the project that will be carried out in three years, also participate researchers and organisations of other countries: such as France, Iceland, Italy and United Kingdom.

The second European project is on the “Improvement of tools to control lentivirus in sheep and goats”. This research is under development collaboration with 15 companies, one of them is the Basque Institute of Lactology Lekunberri, and 7 research centres of Europe. The aim of this project is to develop a method capable to detect the virus by using molecular diagnosis. The project is expected to finish next year.

Finally, at national level, the aim of the Institute of Agrobiotechnology and Natural Resources is to improve the control tools of the virus and properly understand mechanisms of the pathogenic nature of the virus. For that aim, DNA vaccines and molecular diagnosis will be used.

In the development of this project, apart from the Institute of Lactology of Lekunberri, various cattle farmers, the Centre of Insemination of Oscoz, ITG cattle raising company and the association of sheep of Latxa Navarra, Navarre Race and Aragon Race participate.

Im Focus: Energy-saving new LED phosphor

The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one sixth, which can significantly improve the energy efficiency of lighting systems.

Light emitting diodes or LEDs are only able to produce light of a certain colour. However, white light can be created using different colour mixing processes.

Im Focus: Quantum gas turns supersolid

Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.

Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...

Im Focus: Explosion on Jupiter-sized star 10 times more powerful than ever seen on our sun

A stellar flare 10 times more powerful than anything seen on our sun has burst from an ultracool star almost the same size as Jupiter

  • Coolest and smallest star to produce a superflare found
  • Star is a tenth of the radius of our Sun
  • Researchers led by University of Warwick could only see...

Im Focus: Quantum simulation more stable than expected

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.

Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
