Huge numbers of camels die in Africa and Saudi Arabia

Analyses are being conducted to confirm or rule out the hypothesis of food intoxication in the countries concerned. Poisoning caused by the ingestion of toxic plants, mycotoxins (microscopic fungi), or mineral deficiencies has also been suggested.

The deaths are probably due to a multitude of factors, which have a detrimental effect on the immune system, including some viruses which could increase the severity of infections or parasitic infestations in animals.

As Bernard Faye, head of the animal resources department at CIRAD, explains: "For years, we have been witnessing new pathologies in camels. There is nothing to suggest that the causes of these diseases are identical because the symptoms are not always the same. "

The morbillivirus of small ruminants

The morbillivirus, which affects small ruminants, is found in Africa, the Arab Peninsula, the Middle East and India. It affects sheep and goats, in particular, but can affect other species. The disease is characterised by a high temperature, body lesions, pneumonia and death within 8 days.

In Ethiopia, during 1995-1996 and in Kenya and Sudan at the start of 2000, the virus PPR (small ruminant virus), was identified as being the potential cause of the death of hundreds of dromedaries. The clinical and epidemiological observations combined with the laboratory results (serology tests, viral detection), would suggest that this virus plays a role in the emergence of an enzootic disease among camel populations in the Horn of Africa. Other pathogens have been isolated but their presence could be due to the fact that the animals’ immuno-defence systems are depressed because of the presence of this virus.

" Additional research is required in order to determine the causes of this disease and to identify whether or not the PPR virus has a role to play, such as continued virology diagnoses, epidemiological studies to measure the respective roles of the virus, other pathogenic agents and environmental risk factors ", according to François Roger, Head of CIRAD’s research unit (UPR) Epidemiology and ecology of animal diseases. " In this way, we could contribute to understanding the causes of the emergence of this disease and its socio-economic impact ".

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
