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: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
