Bluetongue disease has been seen in northern Europe and continental France for the first time

07.09.2006
CIRAD and its partners are in the front line

Since 1999, Bluetongue (BT) has been spreading from the southern and eastern Mediterranean towards northern Europe. Between 2000 and 2004, foci were also observed in Corsica. Vast vaccination campaigns subsequently overcame the disease, which is transmitted to sheep by biting midges of the genus Culicoides.

As Emmanuel Camus, Director of CIRAD's Animal Production and Veterinary Medicine Department, explains: "global warming is favouring the arrival of diseases previously seen as exotic". He adds "we also need to cope with the appearance of different strains serotypes) of the Bluetongue vieus, which means using specific vaccines".

CIRAD is the national reference laboratory for the disease, and will be analysing samples taken by veterinary services from sheep and cattle on 60 farms in six of the départements most concerned (Moselle, Meurthe et Moselle, Meuse, Ardennes, Aisne and Nord), and will be trapping vector insects in those areas.

It is also carrying out research, primarily on:

- molecular characterization of vector insects: this will enable the precise identification of species in terms of morphologically indistinguishable groups or complexes and characterization of their reproduction sites, since it is impossible to identify species at the larval stage;

- the development of a new recombinant vaccine effective on all serotypes (in partnership with AFSSA and INRA);

- assessing Bluetongue serological diagnostic kits;

- spatial modelling of the zones propitious to vectors and dynamic modelling of viral infection so as to pinpoint the zones to be monitored in continental France. Several models are currently being developed and evaluated;

- application of the risk evaluation methodology concerning introduction of the virus into disease-free zones through commercial animal movements.

CIRAD is also coordinator of the European Med_Reo_Net project on Bluetongue and another disease caused by a similar virus: African horse sickness. The project, which involves 17 countries, will be launched in Autumn 2006.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
