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: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
